Embodiment

[0037] This embodiment provides a vehicle-mounted head-up display.

[0038] Please refer to Figure 1-2 , the vehicle-mounted head-up display includes a casing 100 , a light-emitting component 200 , a display glass 300 and a brightness adjustment component 400 .

[0039] The housing 100 defines an accommodation cavity 101 and an opening 102 communicating with the accommodation cavity 101 , the accommodation cavity 101 provides an installation place for the light emitting component 200 and the brightness adjustment component 400 , and the opening 102 provides an installation place for the display glass 300 .

[0040] In this embodiment, the casing 100 should be configured as a sealed structure except for the above-mentioned opening 102. At this time, after the light-emitting component 200, the display glass 300, etc. are installed in place, on the one hand, the entire vehicle-mounted head-up display can be avoided. Light leakage improves the utilization rate of light; on the o...

Abstract

The invention discloses a vehicle-mounted head-up display. The vehicle-mounted head-up display comprises a shell, a light emitting component, display glass and a luminance adjusting component, whereinthe shell is used for defining a receiving cavity and an opening connected with the receiving cavity; the light emitting component is arranged in the receiving cavity and comprises a plurality of light emitting units with different light-emitting luminance; the luminance adjusting component is used for controlling the light emitting units to be turned on and off and / or changing the luminance of the light emitting units so as to enable the plurality of light emitting units to be matched with different light-emitting luminance. The luminance of the vehicle-mounted head-up display can be adjusted in a large range; meanwhile, the luminance can be uniformly changed in the adjusting process; and the vehicle-mounted head-up display has good visual presentation under various illumination conditions.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a vehicle-mounted head-up display. Background technique [0002] In order to display navigation, speed, fuel level and other information to the driver in an intuitive way, more and more vehicles are equipped with a head-up display (HUD), so that the driver does not need to take his eyes off the road when obtaining relevant information. Conducive to driving safety. [0003] In order to enable the various signals of the display to be clearly displayed under various lighting conditions, it is usually required that the brightness of the display can change with the environment, usually 10,000 cd / m2 during the day 2 ~40,000 cd / m 2 The brightness needs to be 30cd / m at night 2 to 100cd / m 2 brightness. However, the screen brightness of the existing head-up display is fixed, or the range of change is too small, or the change is uneven, which cannot meet the use requirements. Conten...
