Energy-saving type vehicle-mounted backlight source adopting FPC folding type design

Abstract

The invention discloses an energy-saving vehicle-mounted backlight source adopting an FPC folding design, and relates to the technical field of electro-optics, the energy-saving vehicle-mounted backlight source comprises a vehicle-mounted backlight source body, a middle frame, an FPC light bar and a lower frame, the vehicle-mounted backlight source body further comprises glass fixing foam rubber, the middle frame is installed at the bottom of the glass fixing foam rubber, a clamping groove is formed in the outer surface of one side of the middle frame, and the FPC light bar is arranged in the clamping groove. The bottom of the middle frame is provided with a light control film, the bottom of the light control film is provided with a lower brightness enhancement film, the bottom of the lower brightness enhancement film is fixedly connected with a diffusion film, the bottom of the diffusion film is provided with a light guide plate, the bottom of the light guide plate is fixedly connected with a reflecting film, and the inner side of the middle frame is provided with an FPC light bar. The vehicle-mounted backlight source has the advantages that the structure is simple, the design is novel, materials are fully utilized, a base does not need to be additionally arranged to fix the FPC flat cable, the stability of the FPC flat cable is improved, the market competitiveness of the backlight source is improved, popularization is facilitated, the light-emitting efficiency and uniformity of the vehicle-mounted backlight source are improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of electro-optic technology, in particular to an energy-saving vehicle backlight with FPC folding design. Background technology [0002] With the continuous development of the automobile market, the competition of on-board backlight in the industry is becoming more and more fierce. There is a lot of waste of materials in the traditional FPC structure design. The new design scheme can improve the utilization rate of materials, so as to reduce the cost of backlight and enhance the market competitiveness. Therefore, FPC folding design is applied. At present, the conventional on-board display screen usually adopts direct backlight or side light backlight, Among them, the display screen with direct backlight has higher contrast, color saturation and display fineness. [0003] The prior art has the following shortcomings: the existing side light FPC needs to supply power to the driving main board through the FPC cable, but the e...

[0002] With the continuous development of the automobile market, the industry's automotive backlight competition is becoming more and more fierce. There is a lot of material waste in the traditional FPC structure design. The new design scheme can improve the utilization rate of materials, thereby reducing the cost of the backlight and enhancing market competition. For this reason, the FPC folding design application was born. At present, conventional vehicle display screens usually use direct-lit backlight or edge-lit backlight. Among them, the contrast and color saturation of the display screen with direct-lit backlight and higher fineness

[0003] The existing technology has the following deficiencies: the existing edge-lit FPC needs to supply power to the main board through the FPC cable, but the existing FPC cable needs to be additionally provided with a base to fix the FPC cable, the structure is complex, and the stability is not high. If it is not fixed, it will be easy to loosen, resulting in poor contact and damage. The luminous efficiency of the light source is not high, the light source is unstable, and it is easy to cause local darkening
