FREQUENTLY ASKED QUESTIONS
GENERAL INFORMATION ABOUT LAPTOP SCREENS
Question: How do we find the right screen for you?
Ans: We source authentic information from manufacturers and then personally verify it to advertise the screen with appropriate models.
Question: Do you sell genuine screens, and what is the quality of the product?
Ans: We source laptop screens directly from the manufactures like Samsung, LG, AUO, Sharp, ChiMei, Chunghwa, Toshiba and many more. We only sell genuine high quality screens which are exactly same installed in laptops by laptop manufacturers like Apple, Dell, HP, Sony, IBM Lenovo, Asus, Acer, Samsung, Packard Bell, MSI and Toshiba etc.
Question: Do you sell “Brand New” screens?
Ans: We sell brand new screens unless otherwise stated.
Question: What is compatible screen?
Ans:Laptop screen manufacturers release new model (version) of LCD screens from time to time. New model may have better quality, updated electrical parameters etc. As a result, there is may be hundreds of compatible LCD models available in the market. It will require millions of investment to stock every model of the screen. There is also possibility exact model may be outdated and no longer available in the market or price is very expensive.
We offer replacement screens which are 100% compatible with original LCD screen. It may be cheaper in price. This allow us to offer you better deals on new LCD models.
Question: What is the difference between CCFL and LED screens?
Ans: LCD panels are divided according to the backlight into two types CCFL and LED.
CCFL (Cold Cathode Fluorescent Light – High Intensity Discharge Lamps) was mostly used in older laptops. It comes in two types 1-CCFL or 2-CCFL and also required an inverter to power the lamps. 1-CCFL or “single backlight” contains one bulb to light it up and a pair of wires at the bottom. It has one white inverter connector that is used for plugging into inverter board. 2-CCFL or “dual backlight” contains 2 bulbs, has 2 inverter pair cables as well as 2 inverter connectors.
LED (Light Emitting Diodes) type of lighting has been widely used since the early 2010s. LED’s are becoming more famous because of higher efficiency in terms of size, resolution, power consumption, heat generation etc.
Question: Is screen backlight upgrade CCFL to LED possible?
Ans: Upgrading CCFL to LED backlight is generally not possible. It is so because these screens have totally different connectors and power supplies which makes them incompatible. However, there are cable adapters available that allow LED screen to work with CCFL screen. These adapters are only compatible with certain laptop models. For the rest, in order to change or upgrade CCFL to LED, the motherboard will have to be replaced, which may result even more than the cost of the laptop.
Question: Laptop screen surface Glossy vs Matte?
Ans: Laptop screen surface play a key factor while we are doing some professional work on laptop or playing games, watching movies, or sports etc. Laptop manufacture sell laptop with Gloss or Matte finish display depending on type of the laptop. When you purchase a replacement laptop screen, you might be offered with a choice. If original (faulty) screen has matte finish, you can replace it with a new one that is glossy, and same can happen vice versa.
Glossy Screen
Pros
These screens shine like a mirror if blank and are highly effective for indoor work. These are meant for having good visibility in darker environment. You can watch videos and play games with more vividly colours. So there is a sharp and bright colour that you can look for a good work.
Cons
If glossy screens are used in daylight or in very well lit environment then you might not be able to catch a glimpse of what is going on the screen. It is something problematic to use this otherwise valuable version in the screen introduction.
Matte Screen
Pros
Matt finish screen have rough surface. It does not glow or shine, and that is why it is most suitable for the office environment where there is a strong light. It can be easily used in the daylight, and not causes a reflection in the eyes.
Cons
Matte finish allows you to work in bright light, and can be used in daylight as well with quite an ease. It is not going to show you that bright picture if you want to see videos or play games.
Technical Details
All screens are prepared with the finishing touch of Polarized Plastic, and it is the prime factor that determines whether the screen would be glossy or matte at end. The backlighting concept has made glossy screens popular as gloss panels are able to produce sufficient light that there is no room left for the external light that reflects form screen itself.
The fact is that most of laptops come with glossy display now but it doesn’t mean that matte finish is not in demand. You can easily replace one with another.
Laptop manufacturers have given different names for their glossy display. For example, Acer has named its glossy laptop screen as CrystalBrite, Asus, as Colour Shine and Dell as True Life.
Here are the names by which glossy display are called by laptop manufacturers:
Acer – CrystalBrite
Acorn – Vybrio
Apple – Glossy
ASUS – Colour Shine
Dell – True Life
SONY – XBRITE, X-black, Clear Bright, Clear Photo LCD
Gateway – Ultra Brite
HP-Compaq Bright View
IBM-Lenovo Vibrant View
LG – Fine Brite
NEC OptiClear, SuperShineAG Neovo – NeoV Optical Filter
Ahtec – Glare
Alienware – Clear View
Averatec – Avera Brite
Everex – Diamond Brite
Fujitsu – Crystal View, SuperFine
Packard Bell – Diamond View
Sager – Super Clear
Toshiba – Clear SuperView
Question: What is screen resolution and how do I know my laptop screen Resolution?
Ans: The screen resolution refers to the number of pixels within the display.
Resolution name:
Different names are given to different types of resolution by the LCD industry. These are identified with abbreviations. For example: 1366×768 is given the name HD (High Definition) and 1920×1080 for FULL HD. The latter has a very high resolution and displays an image that is twice the amount of pixels as compared to an HD screen.
Pixel length X Pixel width
This kind of measurement denotes the pixels or dots horizontally times by the pixels or dots vertically. For example 1366×768 means 768 horizontal lines each containing 1366 pixels and giving a total pixel count of 1049088 which is just over a million pixels to make up the entire image.
Shorthand name:
Manufacturers have coined additional shorthand names for the same product. These shorthand names may be numbers and letters in an abbreviated form that signify the screen resolution. For example, the shorthand name 768p is also known as HD and 1080p as FULL HD.
You can find your screen resolution by visiting following links “What is My Screen Resolution“ or “How to Check Screen Resolution on Laptop“.
Another way is to go through laptop manual. It is always mentioned in the specifications section. You can also go to manufacturer’s website and search laptop model and its specification.
Most common display resolutions
WSVGA 1024×600
WXGA 1280X800
WXGA 1440×900
WSXGA 1680×1050, 1680×945
WUXGA 1920×1200,
SXGA 1400×1050
UXGA 1600×1200
QXGA 2048×1536
XGA 1024×768
SXGA 1280×1024
“W” stands for widescreen aspect ratio of 16:9 or 16:10.
Some latest screen resolution displays
Retina Display
Retina Display is used by Apple for screens having a higher pixel density. For the third generation MacBook Pro (15”), the resolution is 2880X1800 which makes the total pixel count of 5,184,000 and for the MacBook Pro (13”), the resolution is 2560X1600 making the pixel count to 4,096,000. With such high resolution, the quality of display is very high.
Ultra HD
Leading laptop manufacturers are launching laptops with ultra HD screen which has a very high resolution of 3840x2160p which is four times higher than that of the standard Full HD screen.
Question: Can screen Resolution upgrade or downgrade?
Ans: Laptop screen display upgrade or downgrade is generally not recommended. The reason being the resulting distorted display. Problems like improper working of video cards may occur. Video cards are used for image processing and get overloaded when connected to a higher resolution LCD screen because higher processing power requirement. So improper working of video card will directly affect the image display. But you can always replace an old laptop screen with a new one if both of them have same resolution and other specification.
Question: How to find laptop screen model?
Ans: If you want to buy new screen with screen part number, you will need exact part number of the screen. Sometimes it is tricky to find screen part number. Usually screen part number is written either on back side of screen or inverter. The most important information is the manufacturer’s code and the screen size. Fortunately, the information for both can be found in one place, on the back side of the screen itself. For example let’s say the code you find on the back of your laptop screen is LP156WH2(TL)(A1).
This translates into having a LG Philips 15.6 inch screen. The “LP” is the code for LG Philips and the “156” is the code for the screen size of 15.6 inches. You’ll often see this code next to or above the UPS bar code for the screen.
A list of LCD screen manufacturers along with their abbreviations is given below. The first few letters of the model number correspond to the manufacturers.
AU Optronics – B
ChiMei Innolux – N
Chunghwa – CLAA
HannStar – HSD
Hitachi – TX

Here are some examples of different manufacturers screen part numbers.
Question: If I purchase a screen from CAPRICTECH.CO.UK .CO.UK and one directly from the manufacturer what is the difference between these two?
Ans: There will be no difference in quality but we offer a wide range of screens and competitive prices than manufacturers.
Question: Do you send a VAT invoice?
Ans: We are a UK VAT registered company and we do provide a VAT invoice with every purchase. This will be emailed to you when the item has been dispatched along with the tracking number.
Question: What is Dead Pixel policy?
Ans: Dead/ defective pixels are the pixels that do not perform properly. Few dead pixels do not make a screen completely useless because the pixel count goes in millions. Many standards have been set from time to time which provide the guidelines for the permissible defective pixel limit such as ISO 13406-2, ISO 9241-302, ISO 92341-303 etc. If 4 or 5 pixels are defected or dead, screen manufacturers consider it acceptable as it does not make screen poor quality or affect screen quality
We sell brand new screens and normally the error ratio is less than 0.1%. “Screen display up to 2 fixed pixels is within industry standards and is therefore considered acceptable display” However if there is any issue, please email us and we will try to resolve it.
Different laptop manufacturers have different dead-pixel policies. Here are the links to some leading laptop manufacturer’s dead pixel policy which will give you a better understanding:

Question: How much is delivery cost?
Ans: We offer free shipping within the UK on all our products. For shipping to cost and rest of the world, please visit link delivery tariff.
LAPTOP CHARGER BUYERS GUIDE
Laptops are mobile gadgets that use rechargeable batteries as their power supply. If the laptop has not been plugged in for a while, the batteries will have to be recharged using a charger which is plugged into an electrical outlet. There are hundreds of different laptops models in the market, each one uses its own kind of adapter. Adapters come in different power output and connectors. Using an adapter with different technical specification may not work with laptop. Buying a correct replacement Laptop Charger require some technical information of existing faulty (original) charger. Replacing a laptop adapter or buying a spare adapter require doing some homework before making the final purchase. First need to look at laptop model, voltage and amperage of laptop required replacement power adapter.
With this info on hand finding a correct replacement laptop chapter from website will be easier. Adapter voltage and connector type must match with original (faulty) adapter, but it is ok if the amperage is same or little above the amperage of the original (faulty) adapter. A universal power adapter is a great option as most new universal adapter can adjust their power settings automatically to match the laptop and they also come with a variety of connector tips.
Types of Laptops Adapters
The two main kinds of power adapters for laptops are AC adapters and DC adapters. Adapters often called chargers, are used to convert the electricity from the outlet into power that the laptop can use.
AC Adapter
AC adapters transform the AC power from electrical outlets into DC power that is used by small appliances like computers, cell phones, laptops and DVD players. Laptop batteries provide DC power when the laptop isn’t connected to the outlet.
DC Adapter
It might not seem necessary to use a DC adapter when plugging the adapter into a DC electrical outlet, but the voltage supplied by most DC outlets is not high enough to meet the requirements of a laptop. That is why a DC power adapter is needed to boost the voltage so that it can be safely used to charge a laptop. Cars, outlets on planes, batteries and solar power panel all supply DC power.
Universal Laptop Adapters
The universal power adapter is another power option for laptop owners. These adapters usually cost more, however, they are able to adapt to any voltage and power source. In theory, universal adapters can power any kind of laptop, which makes them very useful for those who travel often and don’t know what kind of power source they might run into. Universal adapters come with different connectors tips that fit a variety of laptops. Some laptops use unique tips so it might be challenging to find a universal adapter for those unique connections.
Laptops Use DC Power
All laptops are powered by Direct Current (DC), which is the flow of electricity in only one direction. The majority of electrical outlets use Alternating Current (AC), but laptops cannot operate on this constantly varying electric current and this is why an adapter is required to convert the AC into DC.
The adapters, which are those small weighty black boxes that are connected to the laptop and the electrical outlet, allow the laptop to use AC power directly from the electrical outlet. There are also special DC adapters for electrical outlets that only output DC power.
About Voltage
Electrical energy is pulled into the laptop using voltage. Picture the wheels on a paddle boat, which are used to steer and propel the paddle board across the water. The paddle boat in this situation represents electrons. If the laptop and adapter voltages were different, the proper charge won’t be produced and not enough electrical energy will be pulled into the laptop. It is also important to get the correct voltage or the laptop might short out. If the voltage is too high, it could overload the circuits on the laptop. Either high or low voltages can seriously damage the laptop, so it is important that the adapter and the laptop voltages match exactly.
About Amperage
Amperage is the power that the laptop needs to operate and is sometimes called current. It is how much electrical energy that is flowing into the laptop at any given instant. For laptops to function properly, they need a constant amount of the right energy flowing to all its circuits. Voltage is the measure of the amount of potential energy that a laptop is able to use. Laptop power adapters must have amperage that is equal to or exceeds the amperage that is needed by the laptop.
Types of Connectors
Laptop adapters come in different types of connector tips. If you are looking to replace a laptop adapter, you have to closely look at the connector going into the power port of the laptop. Although all laptops are powered by DC connectors, some of them have different shapes.
How to Find the Right Type of Laptop Charger
You need to know the exact type of adapter that your laptop notebook require before you buy. There are many different types of adapters available. They may have same power voltage and amperage but different connector tip or same connector tip but different power. Thus, they are incompatible with each other. Most of the laptop adapters are only compatible with specific laptop brand and model. The laptop model number, power requirements of the adapter and connector type of adapter are required in order to find compatible replacement adapter.
● Look for laptop model number, which is often on a sticker on the bottom of the laptop or back side of the laptop.
● Find the laptop’s power requirements, which are also usually printed on a sticker at the back side of the laptop. Sometimes it might be printed on the power port of the laptop. Take note of the voltage and amperage required.
● See which charger is compatible by checking out the Laptop model number from website by searching with laptop model. It is important that the voltage and amperage of the replacement charger must match written on the the laptop or match with faulty (original) adapter.
● Also, make sure that the charger connector tip matches the connection port on the laptop; otherwise, the adapter won’t work if it cannot connect to the laptop even if specification else is ok.
Although laptops are meant to be mobile, their batteries do have to be charged using adapters ever so often. The 2 main kinds of adapters for laptops are AC & DC power adapters. They both convert power from an electrical source into a form that can be used to power the laptop. For the adapters to work properly, the amperage, voltage and connector type all have to match the requirements on the laptop. Otherwise, the laptop will not charge properly. Only one kind of connector will work on any given laptop, so it is important to get the right connector.

In order for the screen to work correctly, the replacement screen must have same size, backlight type, data connector and resolution as faulty screen. However, to ensure that you are purchasing the correct replacement screen, we’ve created a buyer’s guide to help you through the process so you can quickly select the type of screen that will work for your laptop. But, if you have any doubts, feel free to contact us and we’ll help you in every way possible.
The terms CCFL and LED are the two different types of screens that laptops can use. This is important information to know because one type will not work on a laptop that requires the other. For those needed CCFL model, there are two types of backlights 1-CFFL and 2-CCFL.
CCFL (Cold Cathode Fluorescent Light – High Intensity Discharge Lamps) was mostly used in older laptops. It comes in two types 1-CCFL or 2-CCFL and also required an inverter to power the lamps. 1-CCFL or “single backlight” contains one bulb to light it up and a pair of wires at the bottom. It has one white inverter connector that is used for plugging into inverter board. 2-CCFL or “dual backlight” contains 2 bulbs, has 2 inverter pair cables as well as 2 inverter connectors.
LED screens are the most common, especially in new laptops and they are available in several different types in terms of resolution, data/video connectors and the type of fittings needed depending on the laptop you own. LED’s are becoming more famous because of higher efficiency in terms of size, resolution, power consumption, heat generation etc.
If you have never purchased laptop screen before, then you’ll need to know a little information about your existing faulty screen before you buy replacement. The most important information is the manufacturer’s code and the screen size. Fortunately, the information for both can be found in one place, on the back side of the screen itself.
If you have removed your faulty screen from laptop, simply turn it around and look for the manufacturer’s code which is written on the back. This is the information you need to search for in order to get correct replacement screen. For example let’s say the code you find on the back of your laptop screen is LTN156AT01.
This translates into having a Samsung 15.6 inch screen. The “LTN” is the code for Samsung and the “156” is the code for the screen size of 15.6 inches. You’ll often see this code next to or above the UPS bar code for the screen.
