摘要： An image processing method, an image processing method device, a display device and a computer-readable storage medium are provided. The image processing method includes: receiving an original display screen; determining a target area in the original display screen, wherein an initial brightness of the target area is larger than a maximum allowable brightness; determining a target grayscale value of the target area; and adjusting a grayscale value of the target area to the target grayscale value, so that the brightness of the target area does not exceed the maximum allowable brightness.

摘要： A method and device for detecting compensation parameters of brightness, a method and device for compensating brightness, a display device, and a non-volatile storage medium are disclosed. The method for detecting compensation parameters is applied for a display panel, and the display panel includes a first region and a second region, which include first pixel units arranged and second pixel units arranged, respectively. The method includes selecting a first target region from the first region, and determining a first compensation parameter, according to brightness of the first target region, for at least part of the first pixel units in the first region to perform brightness compensation; and selecting a second target region from the second region, and determining a second compensation parameter, according to brightness of the second target region, for at least part of the second pixel units in the second region to perform brightness compensation.

摘要： The present disclosure provides a display panel, a control method, and a control device thereof. The display panel includes a bending area. The bending area includes a plurality of sub-pixels. The control method includes: obtaining an attenuation parameter of a sub-pixel of at least one color in the bending area, wherein the attenuation parameter is a pre-attenuation amount of brightness attenuation of the sub-pixel; obtaining a pre-register value of the sub-pixel of the at least one color corresponding to grayscale data of a pixel to which the sub-pixel of the at least one color belongs; and adjusting light emission brightness of the sub-pixel of the at least one color based on the pre-register value and the attenuation parameter of the sub-pixel of the at least one color.
