Sizes and resolutions ,backlight type decides the model of  laptop LCD screen. The laptop LCD resolution should not be upgraded or downgraded. Before choosing a screen, please according to your laptop in SIZE , in RESOLUTION and in BACKLIGHT TYPE, order the right screen.

2.Resolution Matters.

NOTE: Laptop LCD resolution should not be upgraded or downgraded, otherwise LCD Cable & Inverter will be burnt.

We recommend  customers to buy the same LCD resolution as they have.

You can find the LCD resolution of your Laptop by the following way:

For Windows XP or older: go to Start -> Control Panel -> Display Properties

For Windows Vista: Right-Click on Desktop -> Graphics Properties 

Here is some common used reference for you:

Or you can use on-line check service, please note that the on-line tool tells your screen resolution and it only makes sense if you did not change factory default screen settings in Windows or Mac OS.

On-line Resolution Check.

3. Backlight Type.

Generally, there are two types of backlight in the market, CCFL  and LED backlight. CCFL(Cold Cathode Fluorescent Lamp) needs an inverter, but LED backlight needn’t, which uses light-emitting diodes as a source of light.  Now the used most is CCFL backlight.  As we know that desktop has double or three backlight for the monitor brightness, but taking account of power issue, notebooke screen brightness is reduced, so most of notebook screens only use  Single backlight, especially in small size, and some use Dual backlight. 

Single backlight,only one bulb with only one inverter connector in the screen, most used in the market.

So Dual backlight means: two bulbs in the screen with two inverter connector, not so much used.

LED backlight is a new type, used in some latest models. Led screen only has one socket to connect a video cable, no inverter cable. Usually, users can find the specifics in its laptop if using a LED screen.

NOTE:

There are mainly two types of LCD screen on the market, Matte and Glossy screens.  In order to scatter reflected light on the LCD screen surface, there’s a anti-glare finish on Mattescreens. And Glossy screens remove the optical coating, increasing a highly reflective coating, that will effectively improve the performance of contrast and color.   So Glossy screens are better for graphics and video display. Matte screens are beneficial to eyesight protection, especially work for a long time.

HERE comes a diagram for different companies call its own glossy screens:
