Problems solved by technology

However, in the current AMOLED flexible display products, both sides of the AMOLED are curved surfaces, and the curved display area presents a display with different curvatures. Offset phenomenon, that is, when viewed from different angles, there will be different degrees of color shift in different positions of the display area

Abstract

The invention provides a gamma voltage adjusting method, driving method and device for a curved display panel, and the method comprises the steps: determining the first gamma voltage of the plane display region of the curved display panel in a white balance state when the curved display panel is placed horizontally; according to the bending degree of the curved-surface display panel, dividing thecurved-surface display panel into at least one curved-surface display region, and bending each curved-surface display region by a preset angle relative to the plane display region; determining a second gamma voltage corresponding to each curved surface display region in a white balance state; and determining a compensation voltage corresponding to each column of data lines in each curved surface display region according to the first gamma voltage and the second gamma voltage. The display effect of the curved 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, driving method and device for a curved display panel. Background technique [0002] 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 excellent characteristics. [0003] Generally, after each piece of AMOLED is prepared, it is necessary to modulate the brightness of each level of grayscale according to a predetermined gamma (Gamma) standard curve, so that the brightness of each level of the AMOLED conforms to the gamma standard curve, so that the display When viewing an image, ensure that the AMOLED can accurately display details of different bri...
