Embodiment 1

[0034] like figure 2 As shown, this embodiment provides a display device, including a display panel 200, and a dynamic grating 100 is provided on the light-emitting surface side of the display panel. The dynamic grating 100 can change the width and position of its opening S1 to control the outgoing direction of light. , can be obtained as Figure 5 In the display results shown, 1 is the image observed in the first viewing area, and 2 is the image observed in the second viewing area.

[0035] The width and position of the opening S1 of the dynamic grating 100 of the display device in this embodiment can be changed, and the direction of light passing through the dynamic grating 100 can be changed, so it can display two images with adjustable angles.

[0036] As known to those skilled in the art, the viewing angle of the display device is related to the pitch of the grating (the sum of the adjacent light-shielding area S2 of the grating and the width of the opening S1), the wid...

Embodiment 2

[0049] This embodiment provides a display method for the display device of Embodiment 1. The display panel of the display device is divided into a first display area and a second display area. The display method specifically includes: during the display process, changing the dynamic grating The width and / or location of the opening.

[0050] Preferably, during the display process, by changing the width and / or position of the opening of the dynamic grating, the first display area and the second display area can be observed in turn in the first view area, and the first display area and the second display area can be observed in turn in the second view area To the second display area and the first display area; wherein, when the first display area can be observed in the first viewing area, the second display area can be observed in the second viewing area, and when the first viewing area can be observed When reaching the second display area, the first display area can be observed ...

Abstract

The invention provides a display device and a display method thereof, belongs to the technical field of displaying, and can solve the problem that the visual angles of the conventional double-vision display device cannot be adjusted. The display device provided by the invention comprises a display panel and dynamic grids arranged on the light emitting sides of the display panel, wherein the widths and the positions of the dynamic grid can be changed, so as to control the emitting directions of light.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display device and a display method thereof. Background technique [0002] Flat panel displays have the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range. Therefore, it is widely used in consumer electronics or computer products such as medium and small portable TVs, mobile phones, video recorders, notebook computers, desktop monitors, car monitors, and projection TVs, and has gradually replaced cathode ray tubes. (Cathode Ray Tube; CRT) has become the mainstream of displays. In recent years, the flat panel display market has grown significantly, especially in computer applications. Requirements such as large area, high resolution, wide viewing angle and fast response time have also become the key points for consumers to judge the quality of liquid crystal displays. [0003] Although a...
