A display panel is provided. At least two of each of first pixels, each of second pixels, and each of third pixels of the display panel are alternately arranged. A shape of each of first pixels includes an ellipse or a circle. A shape of an edge of each of the second pixels or each of the third pixels corresponds to a concave arc. A sum of a radius of curvature of an edge of each of the first pixels and a width of a predetermined gap is equal to a radius of curvature of the concave arc corresponding to the edge of one of each of the second pixels and each of the third pixels. An aperture ratio of a pixel is effectively increased.

A display panel has a ratio y1 of an aperture ratio of the red pixel to an aperture ratio of the green pixel being in the range of 0.78e{circumflex over (&#x2003;)}(&#x2212;1.98r)&#x2264;y1&#x2264;2.297{circumflex over (&#x2003;)}(&#x2212;1.85r), and 0.1&#x2264;y1&#x2264;3, where r is a ratio of a luminous efficiency of the red pixel to a luminous efficiency of the green pixel. A ratio y2 of an aperture ratio of the blue pixel to the aperture ratio of the green pixel is in a range of 1.32e{circumflex over (&#x2003;)}(&#x2212;10.7b)&#x2264;y2&#x2264;5.95e{circumflex over (&#x2003;)}(&#x2212;14.1b), and 0.3&#x2264;y2&#x2264;4, where b is a ratio of a luminous efficiency of the blue pixel to the luminous efficiency of the green pixel.

A display panel is provided. The display panel includes at least two first pixels, at least two second pixels, and at least two third pixels. An area of the first pixel, an area of the second pixel, and an area of the third pixel are inversely proportional to a luminous efficiency of a luminescent material of the first pixel, a luminous efficiency of a luminescent material of the second pixel, and a luminous efficiency of a luminescent material of the third pixel, respectively. The disclosure can avoid the drawback of color shift of the display panel.

A Mura compensation method and device for a curved screen are disclosed. The method includes: dividing each of curved portions into blocks; acquiring measured luminance values of each of the illuminated sub-pixels in a non-curved portion and measured luminance values of each of the illuminated blocks in the curved portions according to grayscale values, wherein each of measured luminance values has a corresponding relationship with one of the grayscale values; and using the measured luminance values and the grayscale values in a gamma relational expression, solving for coefficients and a gamma value in the gamma relational expression by a fitting process, finding a theoretical luminance value corresponding to each of the grayscale values in a gamma curve according to the gamma value, and using the theoretical luminance value, the coefficients, and the gamma value in the gamma relational expression to solve for a compensation grayscale value.

First photographed images taken at a plurality of angles and brightness information of each of the first photographed images are obtained. According to the brightness information of each of the colors, a relational model is established. Second photographed images taken at a plurality of angles and brightness distribution information of each of the second photographed images are obtained. The brightness distribution information is corrected based on the relational model. Measured brightness values are obtained, and gray level correction values for a preset gray level is calculated. Color deviation is corrected based on the gray level correction values.
