Virtual curved surface display panel and display device

Abstract

The invention discloses a virtual curved surface display panel and a display device. A concave lens array is arranged on the display surface namely a light-exiting surface of a flat panel display panel according to the image-forming principle of a concave lens; focal lengths of all concave lenses are designed to be symmetrically distributed relative to the vertical central symmetry axis of the display surface, and in all concave lenses on the same side of the central symmetry axis, the focal lengths of the concave lenses, with the distances being the same as the central symmetry axis, are the same, and the focal lengths of the concave lenses, with the distances being not the same as the central symmetry axis, are not the same; by adjusting the focal lengths of all the concave lenses, the image distances of images formed by all pixel units in the flat panel display panel are guaranteed to be not the same, and an adjusted image formed by imaging presents a curved surface in space, so that the screen effect of a virtual curved surface in turns of flat panel display is realized, and visual impact effect during viewing is improved.

Description

Technical field [0001] The invention relates to the field of display technology, 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, and the use of curved display can make the user's visual experience more comfortable, the scene feeling of the painting is more realistic, and it can bring better immersive effects. [0003] In order to achieve curved display in the prior art, a curved display panel is usually formed by physically and mechanically bending a flat display panel. However, this method of achieving curved display will cause problems such as light leakage of the display panel and abnormal color display due to the deformation of the fringe field. .

AI Technical Summary

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.
