Problems solved by technology

The design of the three-stage radius of curvature will bring the following problems. At the sudden change of curvature, because the display panel is subjected to shear stress, the glass substrate of the display panel is no longer optically isotropic, but has birefringence, making linear polarization After the light...

Embodiment Construction

[0033] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a curved surface display panel and a stress detecting and voltage adjusting method thereof, and relates to the technical field of display. According to the invention, the display area of the curved surface display panel is provided with a pixel area arranged in an array mode. The non-display area of the curved surface display panel is provided with a voltage adjusting unitand at least one set of stress sensing units. Each stress sensing unit comprises a plurality of pressure sensing sensors arranged in sequence. The connecting line of all the centers of the pressure sensing sensors is a curve in a first plane. The first plane intersects with the extending direction of the bending axis of the curved surface display panel. Each pressure sensing sensor is electricallyconnected with the voltage adjusting unit through a pressure sensing signal line. The voltage adjusting unit is used for receiving the pressure sensing detection signals of the pressure sensing sensors through the pressure sensing signal lines, and adjusting the voltage of at least one part of the pixel area according to the pressure sensing detection signals. Therefore, the voltage of a sub-pixel area can be adjusted according to the pressure sensing signals. As a result, the display brightness of the curved surface display panel in a pure-color display state is uniform, and the non-uniformbrightness phenomenon is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a curved display panel and methods for stress detection and voltage regulation thereof. Background technique [0002] In recent years, with the development of display panels, the existing technology proposes a curved display panel. The curved display panel can give users a better visual experience. The reason is that human eyeballs are convex and curved, and the curved display panel The radian can ensure that the distance between each position on the eyeball and the display panel is more equal, so as to bring a better sensory experience. In addition to the different visual experience, the curved display panel gives people a wider field of view, because the edge slightly curved towards the user can It is closer to the user and achieves basically the same viewing angle as the central position of the curved display panel. In addition to being a large-size display panel, ...
