The present invention provides a display device having an asymmetric prism and a head display device thereof. The display device includes a light emitting module, a prism and an image generating module. The light emitting module is configured to emit light. The prism is arranged on the light ray; the surface of the prism facing the light emitting module is provided with an asymmetric notch so that the light rays are refracted in a predetermined direction after passing through the prism. The image generating module is disposed on one side of the prism and relative to the light emitting module; the image generating module is configured to receive the refracted light, and the projection surface of the image generating module projects the image light in the predetermined direction, thus forming the image in the predetermined position. The display device and head display device enable the displayed image to have a higher, more uniform brightness.
Description
technical field [0001] The invention relates to a display device, in particular to a display device with an asymmetric prism used in a car and a head-up display device. Background technique [0002] Head Up Display (HUD), originally equipped on fighter jets, is used to allow pilots to see important information such as navigation information, fuel and ammunition storage, weapon radar lock status, etc. header image for . Then, with the vigorous development of the civil aviation industry and the improvement of flight safety requirements, general large-scale civil aircrafts are also generally equipped with head-up displays. However, driving a car also requires a high degree of concentration. Therefore, the head-up display has been gradually applied in automobiles in recent years, so that the driver can watch the screen of the electronic product without diverting his eyes. [0003] In the head-up display in the prior art, most of the light sources directly and straightly send ...
