Problems solved by technology
[0005] However, a problem in the transparent display device in the prior art is that if the transmittance of the transparent display film is greater than 80%, most of the imaging light will be lost through the transparent display film, and the imaging clarity will inevitably decrease, and the display effect will be reduced. bad

Embodiment Construction
[0027] In order to improve the display effect of a vehicle-mounted display device, an embodiment of the present invention provides a vehicle-mounted display device. In the technical solution of the embodiment of the present invention, the phosphor powder emits red, green, and blue colors by scanning the phosphor powder with a laser projector. The color light is displayed, thereby improving the display effect of the display device. In order to make the object, technical solution and advantages of the present invention clearer, the following non-limiting examples are taken as examples to further describe the present invention in detail.
[0028] Such as figure 2 as shown, figure 2 A schematic structural diagram of a vehicle-mounted display device provided by an embodiment of the present invention is shown.
[0029] An embodiment of the present invention provides a vehicle-mounted display device, which includes:
[0030] A transparent display screen 30 arranged on the windsh...

Abstract
The invention relates to the technical field of display devices, and discloses a vehicle-mounted display device which comprises a transparent display screen, phosphor, at least one laser projector and a driver. The transparent display screen is arranged on a windscreen; the phosphor is arranged in the transparent display screen; the laser projector is rotationally arranged on a vehicle body, and emits ultraviolet light of first, second and third frequencies, and when the ultraviolet light of the first, second and third frequencies irradiates the phosphor, red, green and blue light is respectively excited; and the driver drives the laser projector to move in a reciprocating manner, and the laser projector scans the transparent display screen during reciprocate movement. According to the technical scheme, the laser projector scans the phosphor, so that the phosphor emits red, green and blue light for display, thereby improving the display effect of the display device; and the phosphor is transparent when not being irradiated by ultraviolet light, and thus, does not influence the sight of a driver.
Description
technical field [0001] The present invention relates to the technical field of display devices, in particular to a vehicle-mounted display device. Background technique [0002] At present, the mainstream of vehicle display is flat panel display, which is installed in the center console. Due to the limited space in the car, the transparent display screen should not be too large, and the display range is limited, which will affect the viewing effect of the driver. [0003] Because the windshield of the car has a large area, and the driver must observe the road conditions through the windshield, if the navigation map can be displayed translucently on the windshield, the driving safety will be greatly improved. [0004] Such as figure 1 as shown, figure 1 A structure of a transparent display device is shown, the transparent display device includes a projector 1 and a projection screen 2, and the projection screen 2 is a transparent display film with a transparency greater than...
