Abstract

The invention provides a display device, a display system and a control method thereof, and relates to the field of display technology. In the present invention, a phase delay structure is provided on the light output side of the display panel, and a viewing angle adjustment structure is provided on the side of the phase delay structure away from the display panel. The viewing angle adjustment structure includes a plurality of mirror units, and the first polarized light formed by the phase delay structure and the second polarized light to adjust the outgoing direction. Through the viewing angle adjustment structure, the output direction of the first polarized light and the second polarized light formed by the phase retardation structure is adjusted, so as to ensure that the transmittance of the first polarized light and the second polarized light is not lost, and the product yield is high. In this case, the vertical viewing angle of the display device can be adjusted.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display system and a control method thereof. Background technique [0002] With the increasing development of display technology, 3D display has become an important development trend in the field of display, which can make the picture more realistic and give users an immersive feeling. However, the existing polarized 3D display devices have a small vertical viewing angle and vertical Problem with narrow viewing area. [0003] At present, two methods can be used to solve the problem of small vertical viewing angle of existing polarized 3D display devices. The first is to reduce the thickness of the upper glass substrate to reduce the distance between the display unit and the phase retardation structure. Add light-shielding stripes on the inside or outside of the phase delay structure. [0004] However, because the first method reduces the thickness o...
