Abstract: Disclosed is a method for regulating brightness and chromaticity of a display panel. The method includes: obtaining original gray-scale data; regulating gray-scales of green, so that brightness values of pixels match a standard gamma curve; matching color coordinates of red and blue using the gray-scales of green; determining a weight coefficient according to a gradation of the gray-scales of green; and calculating and recording color coordinates of target gray-scales of red and blue using the determined weight coefficient.

Abstract: Disclosed are a pixel unit and a display device. The pixel unit includes two sub-pixels of different colors. Each of the sub-pixels is in a regular hexagon shape, and the two sub-pixels share one side. The display device includes two types of the pixel units which include sub-pixels of four different colors of red, green, blue, and white. The pixel unit and the display device can be applied to an OLED display device or other types of display devices.
