Description

Technical Field

[0001] The utility model relates to the technical field of display backlight, in particular to a display backlight installation structure with positioning protection. Background Art

[0002] LCDs are thin, lightweight, and portable, and offer lower radiation emissions than CRT monitors, leading to a rapid increase in demand in recent years. Backlight modules, in particular, are a key component of LCD panels. With advancements in LCD manufacturing technology, backlight module development is trending towards thinner form factors, higher brightness, and lower costs.

[0003] The traditional display backlight module structure generally includes backlight film, plastic frame, light guide plate, reflective sheet and metal back plate. The light inlet of the light guide plate is provided with a light strip. The backlight film includes upper brightening film, lower brightening film and lower diffuser. When the LCD display is subjected to vibration, drop or roller test, the backlight film is easy to move up and down, left and right in the plastic frame groove and each film material is misaligned. The materials rub against each other, and the back coating of the upper brightening film is easy to scratch the lower brightening film; the lower diffuser rubs against the light guide plate, and the light-emitting surface of the light guide plate is easy to be scratched. Finally, the LCD display will show white spots or bright edges, affecting the product display effect. For this reason, we propose a display backlight installation structure with positioning protection. Utility Model Content
