Backlight module and vehicle-mounted display

Abstract

The embodiment of the invention provides a backlight module and a vehicle-mounted display. The backlight module comprises a middle frame, an LED light bar, a light guide plate and a back frame, wherein the LED light bar is fixedly arranged on the inner side of the side plate of the back frame; the light guide plate is arranged in an accommodating cavity; and a fixed connecting piece is arranged onone side of the light guide plate facing the back frame. Therefore, the light guide plate and the back frame are of an integrated structure, the light guide plate and the optical film material in thebacklight module can be guaranteed not to slide on the four sides and the center in the back-and-forth vibration process of a vehicle, the relative position between the light guide plate and the optical film material is kept unchanged, the display stability of the vehicle-mounted displayer is improved, and the use experience and satisfaction of a user are improved.

Description

Technical field [0001] This application relates to the field of folding display technology, and in particular to a backlight module and a vehicle display. Background technique [0002] With the gradual development of in-vehicle electronic technology, the current demand for in-vehicle electronic products is increasing. As cars become more and more used as vehicles for modern people, vehicles exhibit up and down vibrations on the road. Reliability requirements are getting higher and higher. [0003] Common vehicle displays are mainly composed of a backlight module and a display module. The backlight module includes a back plate, a reflector in the back plate, a light source on the surface of the reflector, a light guide plate on the surface of the light source, and an optical film on the surface of the light guide plate. material. As the vehicle vibrates back and forth, the backlight module usually moves horizontally and vertically. The light guide plate and the optical film slide ...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides a backlight module and a vehicle-mounted display, which can solve the problem that in the prior art, the backlight module usually moves relative to each other in the horizontal and vertical directions, and the light guide plate and the optical film material slide on the four sides and the center. It even jumps in the vertical direction, resulting in relative displacement friction between the light guide plate and the optical film material, resulting in white spots on the backlight module when vibrating, which affects the user experience and reduces user satisfaction.
