Embodiment 1

[0034] like figure 1 As shown, the emission device 20 is a transparent display device 21, and the transparent display case is arranged on the front windshield. substrate, and a liquid crystal layer 213 is disposed between the two substrates.

[0035] Specifically, the transparent display device 21 can be inlaid on the front windshield 10 or directly integrally formed with the front windshield 10 . Wherein, the transparent display device 21 is a display panel without a backlight, and its specific structure is as follows: figure 2 As shown, the display panel includes a polarizer 211, two layers of substrates arranged on the polarizer 211, the two layers of substrates are respectively the first substrate 212 and the second substrate 214, and the filling between the two layers of substrates There is a liquid crystal layer 213 . When the transparent display device 21 is working, the external sunlight or light is irradiated on the transparent display device 21, so that the trans...

Embodiment 2

[0039] like image 3 As shown, the emission device 20 is a projection device 22 arranged on the vehicle body, and the projection device 22 irradiates on the front windshield 10 to form an anti-peeping image, wherein the projection device 22 includes a backlight The source is the polarizer 211 arranged on the backlight source, and the two-layered substrate of the polarizer 211 is arranged on the cell, and a liquid crystal layer is arranged between the two-layered substrates.

[0040] Specifically, the emission device 20 provided in this embodiment is displayed in a projection mode, that is, the emission device is arranged in the vehicle body, and the light emitted by it is projected onto the front windshield 10 to form a peep-proof image, and passengers can pass polarized glasses 30 to watch the resulting privacy image. Wherein the display device is a projector, and the display part of the projector includes a backlight, a polarizer 211, and two layers of substrates for the bo...

Abstract

The invention relates to the technical field of display devices, in particular to a display device and a transportation vehicle. The display device comprises an emission device which forms peeping prevention pictures on a front windshield of a vehicle body and polarized glasses used for viewing the peeping prevention pictures. According to the technical scheme, the peeping prevention pictures are formed on the front windshield of the vehicle body through the emission device, and therefore the formed pictures can not interfere the driving of a driver, the driver can drive attentively, and meanwhile passengers can wear the polarized glasses to view the pictures on the front windshield. By means of the display device and the transportation vehicle, the emission device forms the peeping prevention pictures on the front windshield, so that the display area is increased, meanwhile, the view of the passengers is facilitated, the passengers located on the rear portion of the vehicle body can observe the pictures clearly, and the visual effect displayed when the passengers view the pictures is improved.
