LCD Screen Size
This is measured diagonally from top corner to an opposite bottom corner and is usually stated in inches.
LCD Screen Backlight Type
Essentially there two types of backlights currently on the market:
- LED (newer technology)
- CCFL (older technology)
It is extremely important to know your original screen backlight type as they are not interchangeable.
CCFL backlit screens typically have two extra wires, white and pink, sometimes green and blue, that connect to a high voltage inverter which provides high voltage power to the tube light hidden within the screen. LED backlit screens typically only have one connector and no extra wires, since the LED backlight low voltage power is supplied directly via the video cable.
LCD screen resolution
Screen resolution is the number of unique dots (pixels) that the screen is built with. Resolution is recorded with two numbers, first the number of pixels from left to right followed by the number of pixels from top to bottom: e.g. 1920 x 1080. It is not recommended to upgrade your resolution because a higher resolution may put increased loads onto the laptop’s graphics chip causing it to run hotter and to wear out quicker. Upgrading may also require additional parts other than the LCD.
Matt or Glossy
This is an easy one, simply put it is entirely your choice, Matt and Glossy screens are completely interchangeable.
Matt screens are coated with an anti-reflective (haze) coating or plastic film and will prevent reflections from windows and lights. Glossy screens have a mirror-like surface and will reflect external light sources, but at the same time will appear sharper with more vivid colours.
