Abstract

Embodiments of the present invention provide a display component and its control method, a head-up display, and an automobile, which relate to the field of display technology and can solve the problem of increased cost caused by the need for two display screens to provide image sources in the existing HUD. Including: a light-emitting component; a DMD device, used to reflect the light emitted by the light-emitting component, the DMD device includes a plurality of micro mirrors, each micro mirror has a first deflection direction and a second deflection direction; the first projection system is used to receive the The light reflected by the micro mirror deflected in a deflection direction; the second projection system is used to receive the light reflected by the micro mirror deflected in the second deflection direction; the control device is used to alternately output the first image signal and the second image to the DMD device signal, and control when outputting the first image signal, only the first projection system outputs the first image after receiving the light reflected by the microlens, and when outputting the second image signal, only the second projection system outputs the light reflected by the microlens second image.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a display component and a control method thereof, a head-up display and an automobile. Background technique

[0002] HUD (Head Up Display), also known as head-up display, can project important driving information on the windshield or other optical devices of the car, so that the driver can observe important driving information without bowing his head, so that the driver The line of sight can always be kept on the road, thus improving driving safety.

[0003] At present, the HUD is generally a status projection HUD, that is, a short-distance projection, which images the common driving information displayed by the image source, such as vehicle speed, rotation speed, fuel level, etc., into a virtual image suspended on the hood. With the development of technology, AR-HUD (Augmented Reality, Augmented Reality HUD), that is, long-distance projection has attracted more and more attent...
