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.
