Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The embodiments of the present invention control the luminous flux output of one or more micro-projectors according to the brightness of ambient light, so that the luminous flux output of one or more micro-projectors can adapt to ambient light with different brightness, and then transmit the driving information Projected on the windshield, a clearer and softer driving information image is displayed, which makes the human eye more clear and comfortable to observe, greatly improves the display effect of the head-up display, and saves on the premise of ensuring the display effect. energy consum...

Abstract

The invention is applicable to the technical field of electronic display, and provides a head-up display method and system. The method comprises the following steps of detecting the brightness of environment light; controlling the luminous flux output of more than one miniature projector according to the brightness of the environment light, wherein the miniature projector adopts a laser light source; receiving traffic information, transmitting the traffic information to the more than one miniature projector, and projecting the traffic information on a windshield by the miniature projector. By the method and the system, the luminous flux output of the more than one miniature projector is controlled according to the brightness of the environment light, so that the luminous flux output of the more than one miniature projector is adapted to the environment light with different brightness; then the traffic information is projected on the windshield by the more than one miniature projector, so that a clearer and softer traffic information image is displayed, and is clearer and more comfortable to observe by human eyes, the display effect of head-up display is greatly improved, and the energy consumption of the head-up display system is reduced on the premise of ensuring the display effect.

Description

technical field [0001] The invention belongs to the technical field of electronic display, and in particular relates to a head-up display method and system. Background technique [0002] The general method adopted by the head-up display system of the car is to use the reflection of the windshield of the car to form a virtual image in front of the windshield, thereby projecting the driving information to the front of the driver, so that the driver needs to refer to the driving information during driving There is no need to lower your head when driving, so you can concentrate on the road ahead. The national standard requires that the transmittance of the windshield of the car must be greater than 70%, so as to ensure that the driver can see the road ahead clearly. That is to say, the reflectivity of the windshield is lower than 30%, and the reflected light intensity of the image reaching the human eye is relatively weak. [0003] The brightness of the image that the human ey...
