1. A display panel, and the display panel comprises a plurality of pixel units aligned in array, and each pixel unit comprises a R pixel, a G pixel, a B pixel and a W pixel, wherein a gamma value of the W pixel of the display panel is set to be a first predetermined value, and gamma values of the R pixel, the G pixel, the B pixel of the display panel are set to be a second predetermined value smaller than the first predetermined value, wherein the display panel is implemented with process steps of:

  • changing the gamma values of the R pixel, the G pixel, the B pixel from the first predetermined values to the second predetermined value as deactivating the W pixel; and

    adjusting a gray scale image of the entire display panel including the R pixel, the G pixel, the B pixel and W pixel to be the first predetermined value as activating the W pixel to raise brightness values of gamma middle gray scales of the R pixel, the G pixel and the B pixel to increase a contribution of the R pixel, the G pixel and the B pixel to a brightness of the display panel as showing a pure color image.
