Embodiment Construction
[0023] The PGU temperature overheating protection method of the head-up display of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0024] refer to figure 1 and figure 2 , the present invention improves the head-up display, and further proposes a method for detecting the temperature of the head-up display PGU. The head-up display is referred to as HUD, which is usually arranged on the CCB beam bracket 50 in front of the vehicle instrument. You can see important driving information such as speed, navigation, etc. without looking down or turning your head, so that the line of sight does not have to shift back and forth, and driving safety is enhanced. As the projection unit of HUD, PGU is the core component of HUD. Its function is to generate HUD output image, which is composed of light source, optical diaphragm, screen and other optical components.
