Abstract: A method for identifying a display current includes: acquiring grayscales of pixels in a to-be-displayed image, where the grayscale of each pixel includes grayscales of a plurality of color channels; calculating an average grayscale of a same color channel of all pixels in the to-be-displayed image; identifying a current value of each color channel and a current offset value of each color channel according to the average grayscale of each color channel, where the current offset value represents a difference between a display current value of a nonmonochromatic image and a display current sum of monochromatic images corresponding to the nonmonochromatic image; and calculating a display current of the to-be-displayed image based on the current value and the current offset value of each color channel.

Abstract: A full-panel display with hybrid regional subpixel layouts is provided. The full-panel includes a display panel having a first region with an array of first subpixels of respective a first color, a second color, and a third color, and a second region with an array of second subpixels of respective the first color, the second color, and the third color. The array of first subpixels and the array of second subpixels are collectively configured to achieve a higher transmission rate in the first region to an accessory installed therein while keep a luminance ratio between the first subpixels unchanged from that between the second subpixels. Optionally, a number density and/or a unit subpixel area of the first subpixels of at least one color is smaller in the first region than that in the second region.
