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 There is also possibility exact model may be outdated and no longer available in the market or price is very expensive.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: 1366x768 is given the name HD (High Definition) and 1920x1080 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 1366x768 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 1024x600
WXGA 1280X800
WXGA 1440x900
WSXGA 1680x1050, 1680x945
WUXGA 1920x1200, 
SXGA 1400x1050
UXGA 1600x1200
QXGA 2048x1536
XGA 1024x768
SXGA 1280x1024
“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
BOE-Hydis – HB or HM or HT or HV
IVO – M
K & D – KD
LG Philips - LP
Matsushita - ED
Mitsubishi - AA
NEC – NL
Quanta - QD
Samsung - LTN or LT
Sharp - LQ or LM
Toshiba - LTM or LTD
Tianma - TM

Here are some examples of different manufacturers screen part numbers.

Question: If I purchase a screen from laptopspares.pk 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: 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:

Apple

Dell

HP

Toshiba

Sony

Acer
