Embodiment Construction

[0034] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] see image 3 , which is a schematic diagram of the first embodiment of a dual-view display device according to the present invention.

[0036] The present invention provides a dual-view display device, which includes: a display panel 21 , a double-layer grating 22 and a backlight source 23 arranged adjacently. In this embodiment, the double-layer grating 22 is disposed between the display panel 21 and the backlight source 23 . Certainly, the position of the double-layer grating 22 is not limited thereto, for example, the display panel 21 is arranged between the double-layer grating 22 and the backlight source 23 . The display panel 21 , the double-layer grating 22 and the backlight source 23 are basically arranged in parallel.

[0037] The display panel 21 is used to provide display information. When implementing dual-view display,...

Abstract

The invention discloses a double-vision display device, which comprises a display panel used for providing display information, and a double-layer grating arranged adjacent to the display panel, wherein the double-layer grating comprises a first grating and a second grating which are arranged adjacent to each other; and the first grating is a slit grating. A grating period of the first grating satisfies the following formula shown in the description. By adopting the double-vision display device, double-vision display can be realized by sticking the double-layer grating to glass substrates of any thickness of different display panels, thereby solving the problem that the realization of double-vision display cannot be guaranteed by sticking the double-layer grating when the thicknesses of the glass substrates of the display panels are different.

Description

technical field [0001] The invention relates to the display field, in particular to a dual-view display device. Background technique [0002] Dual-vision display technology is a technology that uses slit gratings to display two images simultaneously displayed on the display in different directions in front of the display. It is mainly used in vehicle displays, so that passengers in different positions in the vehicle can see different images. In the same way, multi-view display technology is a technology that uses slit gratings to guide multiple images simultaneously displayed on the display to different display directions. [0003] see figure 1 , which is a schematic diagram of an optical path of an existing dual-view display device, which includes: a backlight source 11, a slit grating 12, and a thin film transistor (Thin Film Transistor, TFT) display panel 13, and the slit grating 12 is located between the backlight source 11 and the Between the TFT display panels 13 . ...
