Abstract
The embodiment of the invention discloses a head-up display. The head-up display comprises a backlight source, a display panel and a light ray adjusting structure, wherein the first end of the backlight source is in contact with the first end of the display panel, and an included angle between the plane where the display panel is located and the plane where the backlight source is located is a first preset angle; the light ray adjusting structure is located on the surface, away from one side of the backlight source, of the display panel and is used for allowing light rays generated by the backlight source to be emitted through the display panel to be slant in the direction of the first end of the display panel, and therefore the amount of light rays entering the eyes of a user after the light rays generated by the backlight source are emitted through the display panel is increased; the brightness and the contrast ratio of display images are increased on the display effect observed by the user, the brightness and the contrast ratio of the head-up display are increased, and the requirements of the user are met.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a head-up display. Background technique [0002] With the development of display technology, head up displays (Head Up Display, HUD for short) are more and more widely used. The existing head-up display includes a backlight and a display panel for generating images. The angle between the plane where the display panel is located and the plane where the backlight is located is 19°. In specific use, when the display panel is placed horizontally, the The image generated by the above display panel needs to maintain high brightness and contrast in the full viewing angle of 25° direction, but it is difficult for the existing head-up display to meet the requirements of customers. Contents of the invention [0003] In order to solve the above problems, the embodiments of the present invention provide the following technical solutions: [0004] A head-up display comprising: [0005] ...
