Abstract

The invention discloses a gamma voltage regulating method and device for curved surface display panel, when a panel display area of a curved surface display panel is arranged horizontally, first gamma voltage in a white balance state is determined, and the first gamma voltage serves as the gamma voltage of the panel display area of the curved surface display panel; according to the bending degree of a curved surface display area of the curved surface display panel, the curved surface display area of the curved surface display panel is divided into a plurality of sub-areas, and inclination angles matched with the bending degrees of the sub-areas are determined; when the plane display area of the curved surface display panel inclines in inclination angles relative to the horizontal arrangement, the determined second gamma voltages in the white balance state respectively serve as gamma voltages of corresponding sub-areas, so that when the curve surface display panel performs display output, the plane display area and the curved surface display area are in white balance state without having color error, and the display quality of the curve surface display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gamma voltage adjustment method and device for a curved display panel. Background technique [0002] With the continuous development of display technology, the development process of flexible display panels is gradually accelerated. Due to its low power consumption, bendable and foldable characteristics, flexible display panels will have a profound impact on the application of wearable devices, and in the future flexible display panels will also continue to penetrate with personal smart terminals And be widely used. [0003] Active-matrix Organic Light-Emitting Diode (AMOLED) is an important flexible display panel, which has self-illumination, no backlight, wide color gamut, high contrast, thin thickness, viewing angle Wide range, fast response, can be used for flexible panels, wide operating temperature range, simple structure and manufacturing process and other exc...
