A virtual curved surface display panel and display device

Abstract

The invention discloses a virtual curved surface display panel and a display device. Using the light-splitting principle of the micro-nano grating structure, the imaging height of each micro-nano grating structure is designed to be symmetrically distributed relative to the vertical central symmetry axis of the display surface, and located at Among the micro-nano grating structures on the same side of the central symmetry axis, the imaging heights of the micro-nano grating structures with the same distance from the central symmetry axis are the same, and the imaging heights of the micro-nano grating structures with different distances from the central symmetry axis are not equal to each other. Adjust the imaging height of each micro-nano grating structure so that the image distance of each pixel unit in the flat display panel is different, and the image formed by adjusting the imaging is a curved surface in space, realizing the effect of displaying a virtual curved surface on the flat display. The visual impact effect of viewing is enhanced.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a virtual curved display panel and a display device. Background technique [0002] The curved display screen can better satisfy people's visual experience. The use of curved display can make the user's visual experience more comfortable, and the scene of the picture is more realistic, which can bring a better immersive effect. [0003] In order to realize curved display in the prior art, a flat display panel is usually formed by physically and mechanically bending a curved display panel. However, this method of realizing curved display will cause problems such as light leakage and abnormal color display of the display panel due to the deformation of the fringe field. .

Problems solved by technology

[0003] In the prior art, in order to realize curved display, the curved display panel is usually formed by physical and mechanical bending of the flat display panel, but this method of realizing curved display will cause problems such as light leakage and abnormal color display of the display panel due to the deformation of the fringe field.

[0004] In addition, in the prior art, in order to realize the curved surface display, many modules inside the display panel have to have a flexible design, so the yield rate of the product is low, and the cost of the corresponding product is relatively high.
