Embodiment 1

[0036] Such as figure 1 As shown, this embodiment provides a head-up display device, including: a light source 1, a scanning unit, an angle adjustment unit 3, a display unit 4, and a projection unit 5; wherein, the scanning unit is used to scan the light emitted by the light source 1, Form the scanning light; the angle adjustment unit 3 is used to expand the outgoing angle of the scanning light; the display unit 4 is used to form an image according to the scanning light passing through the angle adjustment unit 3; the projection unit 5 is used to image the image formed on the display unit 4 Perform projection on a preset area.

[0037] It should be noted here that the light source 1 in the head-up display device in this embodiment emits modulated light according to the driving information (such as speed display and navigation display) collected by the image collection unit. Afterwards, the scanning unit scans the modulated light emitted by the light source 1 in a two-dimensio...

Embodiment 2

[0053] This embodiment provides a driving device, including a windshield 6 and the above-mentioned head-up display device provided in Embodiment 1, wherein the preset area is a partial area on the windshield 6 . Specifically, the traveling device includes, but is not limited to, any one of automobiles, trains, airplanes, and ships.

[0054] Since the driving device in this embodiment includes the above-mentioned head-up display device provided in Embodiment 1, driving information can be displayed on a partial area of ​​the windshield 6 of the driving device to make the driver's travel safer.

Abstract

The invention provides a head-up display device and a driving device, which belong to the technical field of display. The head-up display device of the invention includes a light source, a scanning unit used for scanning the light emitted by the light source to form scanned light, an angle adjustment unit used for expanding the exit angle of the scanned light, a display unit used for forming an image according to the scanned light passing through the angle adjustment unit, and a projection unit used for projecting the image formed on the display unit in a preset area. In the head-up display device of the invention, the angle adjustment unit is added to expand the exit angle of the scanned light formed by the scanning unit, so as to shorten the optical path of the scanned light and to reduce the volume of the head-up display device.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a head-up display device and a driving device. Background technique [0002] Heads Up Display, also known as head-up display, is used to project driving information (such as speed display and navigation display, etc.) onto the front windshield side as a virtual image, so that the driver can see clearly without looking down. important information. [0003] With the application of AR (Augmented Reality, AR) technology in the field of HUD, dual-layer display has become a better implementation form of AR HUD at this stage. At present, most of the double-layer display HUD uses two TFT-LCD (liquid crystal display panel) or DLP+TFT-LCD as the display unit (DLP is a display technology of TI company), which has different advantages in terms of power consumption, volume, brightness and cost. insufficient. Contents of the invention [0004] The present invention aims at at...
