To achieve the purpose of controlling visual luminance of LED, the pixel circuit adjust the length of illumination time in a frame. The current and luminance remain constant when LED is turned on. The driving method avoids color shift. In addition, its luminance is comparable to that of the traditional analog driving mode.
