Abstract

An embodiment of the invention relates to the technical field of laser display and discloses a liquid crystal display device and an HUD (head up display) system. The liquid crystal display device comprises a laser light source, a reflector, a driving device, a controller and a display module; the driving device is connected with the reflector, the controller is connected with the driving device, and the reflector is arranged between the laser light source and the display module; the laser light source is used for emitting laser beams, the reflector is used for receiving the laser beams and reflecting the laser beams to the display module, and the controller is used for controlling the driving device to drive the reflector to move, so that the laser beams reflected by the reflector cover the whole back side of the display module, and backlight is provided for the display module. Through the scheme, the problem of heating due to long-time irradiation of the display module can be solved,and the image brightness can be enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser display, and in particular, relate to a liquid crystal display device and a head-up display system. Background technique [0002] Head Up Display (HUD) refers to a driver-centered, blind-operated multifunctional instrument panel, which is used to project important information such as speed and navigation onto the windshield in front of the driver, allowing the driver to You can see important information without looking down or turning your head. [0003] The virtual image generated by the HUD is mainly formed through a reflector, wherein the reflector is generally a windshield. In order not to affect the driving vision, the windshield must have a high transmittance. When the windshield reflects the HUD image, only about 10% of the light can enter the human eye, and the reflection efficiency is low. [0004] The inventor of the present invention found in the process of realizi...
