LCD Screen Explained


A laptop screen also known as LCD screen displays an image generated by the laptop video card. The LCD screen receives data signal from the video card through the LCD cable.

Laptop screens come in many different sizes and resolutions. In order to find the LCD screen size (in inches), you’ll have to measure the screen between the two diagonal corners.

Older laptops had mostly full screen LCD displays. Newer laptops have mostly widescreen LCD displays.

A backlight lamp (also known as CCFL bulb) is the main source of light in any LCD screen. The backlight lamp powers up by the inverter board.


The LCD screen mounts inside the laptop display panel between the screen bezel and display cover. The LCD screen is attached to the screen brackets (display brackets) which are permanently attached to the display hinges.
