Backlight system, display device and automobile

Abstract

The invention relates to the field of display technology and automobile parts and especially relates to a backlight system, a display device and an automobile. The backlight system comprises a backlight module having a backboard, and an optical fiber light guide device. The optical fiber light guide device comprises a light acquisition assembly for collecting and gathering external light rays, at least one optical fiber for conducting the external light rays collected and gartered by the light acquisition assembly, and a scattering assembly for scattering the light rays conducted by the optical fiber to serve as a backlight source. The input end of the optical fiber is connected with the light acquisition assembly; the output end of the optical fiber is connected with the scattering assembly; and the scattering assembly is arranged on the backboard. The backlight system, the display device and the automobile can realize low power consumption and high brightness in a certain extent, effectively ensure display effect and meanwhile, can also extend the service life of corresponding parts, reduce maintenance and repairing cost, can reduce the number of corresponding components, simplify structure, reduce overall weight of the corresponding device and system and save cost and vehicle inner space.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology and auto parts, in particular to a backlight system, a display device and an automobile. [0003] 【Background technique】 [0004] To improve driver convenience, vehicles may be provided with a heads-up display (HUD) that displays information to the driver. The information displayed through the HUD can be projected on the front of the vehicle (such as on the windshield) while the driver is driving so that it can be displayed within the driver's head-up line of sight, so that the driver can pay attention to the driving environment and related driving information at the same time, avoiding The diversion of the driver's line of sight leads to distraction and increases the safety of driving. Among them, the HUD can present the vehicle information displayed on the central dashboard of the vehicle, such as vehicle speed, fuel level, engine temperature and other related information; in addition,...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a backlight system, a display device and an automobile, so that the external light can be gathered and transmitted to the backlight module through an optical fiber light guide device to act as a backlight source, so as to at least solve the problem of synchronously improving the light emission due to the need to enhance the display contrast. The luminous brightness of the diode will greatly increase the power consumption, so that the temperature will be too high, which will affect the display effect, display stability and service life of the corresponding device, or need to increase the bulky and bulky heat dissipation device to occupy the space in the car.
