Abstract

The invention provides a head up display with adjustable backlight. A light sensor is arranged on a display; the light sensor acquires light strength of the environment, brightness of a backlight lamp is automatically adjusted according to a light strength signal from the light sensor by a central processor, and brightness of an image source screen itself can be adjusted. Initial setting of the brightness of the image source screen itself can enable a driver to freely select the habitual image brightness, and automatic backlight adjustment enables the displayed image to adapt to different light environments. According to the head up display, due to the initial setting of the brightness of the image source screen itself, the function of adaptive display backlight adjustment according to environment light can be realized, a virtual image reflected on a projection lens can meet requirements of different drivers, display brightness can also be automatically changed according to environment lights, the displayed virtual image can be seen clearly when the environment light changes, and display effects of the head up display are better.

Description

technical field [0001] The invention relates to a head-up display for vehicles, in particular to a head-up display with adjustable backlight. Background technique [0002] Head Up Display (HUD) is a kind of glass imaging that projects the main information needed by the driver in the form of icons or text in front of its field of vision, so that the driver can pay attention to the driving environment and related driving conditions at the same time. Information, to avoid the distraction of the driver's attention to the road conditions ahead due to the diversion of the driver's line of sight due to viewing the driving data during driving, which can effectively increase the safety of driving. [0003] Such as figure 1 As shown, the structure adopted by the current common HUD product is as follows: the front windshield 2 of the car is used as the reflective surface, the display 1 is set above the instrument panel, and the image is projected on the front windshield 2 through the ...
