In a first aspect, an embodiment of the present invention provides a head-up display, please refer to fig. 1, the head-up display includes: imaging device 10, reflection device 40, beam splitting device 30, measurement device 20 and windshield 50.
The imaging device 10 is disposed on a first side of the light splitting device 30, the measuring device 20 is disposed on a second side of the light splitting device 30, the reflecting device 40 is disposed on a third side of the light splitting device 30, and the windshield 50 is disposed in a reflecting direction of the reflecting device 40. The imaging device 10 is configured to generate a first light L1 with image information. The light splitting device 30 is used for emitting the first light L1 to the reflection device 40. The reflection device 40 is used for reflecting the first light L1 to the windshield 50. The windshield 50 is used for reflecting the first light L1 to human eyes. The measuring device 20 is used for detecting the light intensity of the second light L2 transmitted through the windshield 50, reflected by the reflecting device 40 and emitted by the light splitting device 30 to the measuring device 20, and/or the measuring device 20 is used for detecting the temperature of the position where the measuring device 20 is located.
The imaging device 10 includes a Liquid Crystal Display (LCD). In the head-up display, after the first light L1 generated by the imaging device 10 is emitted by the light splitting device 30, reflected by the reflecting device 40, and reflected by the windshield 50, the first light L1 can enter human eyes, and the human eyes can observe image content, thereby realizing head-up display.
When the sunlight flows backward, that is, after the external second light L2 is transmitted to the interior of the head-up display through the windshield 50, the second light L2 is reflected to the light splitting device 30 by the reflecting device 40, and the light splitting device 30 emits the second light L2 to the measuring device 20 and transmits the second light L2 to the imaging device 10, so that the measuring device 20 can detect the light intensity of the second light L2, and/or the measuring device 20 can detect the temperature of the position where the measuring device 20 is located.
It can be seen that, in the head-up display, the light intensity and/or the resulting temperature of the external light entering the interior of the head-up display can be obtained by the measuring device 20, and then the operations such as turning off the display can be performed according to the light intensity and/or the temperature, so that the head-up display can be protected. Moreover, the light splitting device 30 is used for emitting the second light to the measuring device 20, so that compared with a mode of directly arranging the measuring device 20 on the imaging device 10, the first light can be prevented from being shielded by the measuring device, and a picture emitted by the imaging device 10 is ensured not to be shielded.

If the light intensity detection module comprises the light power meter, the light power meter is arranged on the second side of the light splitting device, light intensity data detected by any point on the light power meter can be used as light intensity of the second light, and light intensity data detected by a plurality of points on the light power meter can be processed and then used as light intensity of the second light.

In practical applications, after the substrate 22 is set, the corresponding relationship or the relationship diagram between the temperature of the substrate 22 and the temperature of the imaging device 10 can be obtained according to experiments, so that the temperature of the imaging device 10 can be obtained quickly by combining the corresponding relationship or the relationship diagram after the temperature of the substrate 22 is obtained according to the temperature detection module.
