What is WLED

ByBrietta Boatman 2020-01-04 1944

WLED full name White Light Emitting Diode (white light diode), WLED as an alternative to CCFL backlight, there is not much improvement in technology. After the backlight of the display screen is changed to use LED, it will have the characteristics of power saving (about 20% less power compared to CCFL), long life and shock resistance.

Side WLED backlight

The side backlight needs to use the light guide plate (glue) to distribute the LED light evenly to the display area, so the concept of light leakage also arises. When the quality of the light guide film (plate) is not good or there is a problem in the adhesion between the structural layers, the light leakage will be very obvious.

Bottom WLED backlight

The bottom uniformly distributed LED module is also a design method, which looks more complex than the first one, and the whole backlight needs to consider the problems of welding and wiring. From the point of view of Tianyuan, when the device is too dispersed, it must have a negative impact on the stability. If RGB LED, it will definitely cause a delay to the response of RGB LED.

Advantages of WLED backlit screen: Low driving voltage, long life, small size, light weight, good color level performance, more uniform brightness, more environmental protection, impact resistance.

Disadvantages of WLED backlight screen: low brightness and contrast compared to (RGB LED).
