Problems solved by technology

[0004] However, since the light 110 reflected by the plane reflector 200 is projected to the concave reflector 300 at an angle (that is, the transmission path of the light 110 reflected by the plane reflector 200 has an included angle θ with the optical axis 310 of the concave reflector 300 ), thus causing the transmission path of the light 110 to increase, making it difficult to miniaturize the size of the head-up display in the prior art

Embodiment Construction

[0040] Hereinafter, embodiments of the head-up display of the present invention will be described with reference to related drawings. For ease of understanding, the same components in the following embodiments are described with the same reference numerals.

[0041] see figure 2 , figure 2 It is a schematic diagram of the first embodiment of the head-up display of the present invention. The head-up display of the present invention at least includes a display unit 10 , a beam splitter 20 , a reflection mirror 30 and a light combining mirror 40 .

[0042] The display unit 10 is used for providing the first light 11 to be projected to the beam splitter 20 disposed on the transmission path of the first light 11 . Wherein, the first light 11 can be unpolarized non-polarized light; the beam splitter 20 can be a non-polarized beam splitter, and can be a block type non-polarized beam splitter or a plate type non-polarized beam splitter; and the display unit 10 can be Liquid Cryst...

Abstract

The invention discloses a head-up display. The hat-type head-up display at least comprises a hat, a reflector, and an image module. The reflector is pivotedly connected to the front edge of the hat. The image module is arranged on the hat and is used to project the images on the reflector. The reflector can reflect the images so as to form visual images on at least one eye of a user. The provided display overcomes the shortages that in the prior art, the head-mounted display is uncomfortable after being worn for a long time and only one eye can see the visual images. The advantages of head-mounted display and head-up display are integrated so that a user can see the visual images in both eyes, and the comfort level is improved after long-time wearing.

Description

technical field [0001] The present invention relates to a head-up display, in particular to a miniaturized head-up display. Background technique [0002] In recent years, with the development of high-tech products, the public's demand for vehicles has gradually changed from the performance of vehicles to the requirements for vehicle safety equipment. Therefore, in order to ensure that the driver does not need to move his eyes to the dashboard to obtain driving information in a complex traffic environment, the setting of the Head Up Display (HUD) can make the driving information appear in front of the driver's sight, so as to Prevent drivers from ignoring external road conditions and affecting driving safety. [0003] Please refer to the figure 1 , figure 1 It is a schematic diagram of a head-up display in the prior art. A head-up display in the prior art includes a display unit 100 , a flat mirror 200 , a concave mirror 300 and a windshield 400 . The display unit 100 pr...
