The difference in the structure of the LED backlight module lies in the backlight light guide plate
Dec 23, 2021
From the perspective of the development of desktop computer monitors, the current new change is that LED backlights have gradually replaced CCFL backlights. Both desktop computer LCD displays with backlights require light guide plates. Therefore, the application of the light guide plate will not change for a long time. From the perspective of notebook computers, with the application of LED backlights and the development of light guide plate extrusion technology, extruded ultra-thin flat light guide plates have a tendency to replace injection-type wedge-shaped light guide plates, which may occupy the current share of light guide plates for notebook computers. market share.
For the backlight module factory, the main difference in the structure of the LED backlight module lies in the change of the light guide plate. When using CCFL, due to the limitation of the tube diameter of 1.8mm~4mm, the light guide plate must be maintained at about 2.0mm on the light entrance side, and it becomes a wedge-shaped board, which makes it impossible for the notebook computer panel to be very thin; however, using LEDs When used as a backlight, the original thickness limit of the light guide plate no longer exists, and the entire light guide plate can be made uniform and thinner, so it can meet the laptop's pursuit of lightness, thinness and shortness.
Therefore, most of the current notebook computers have adopted LED backlights.
