Display panel, display and a method of raising a pure color image brightness of four primary colors
First Claim
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.

Abstract
The present invention provides a method of raising a pure color image brightness of four primary colors, employed to raise a display brightness of a four primary colors display panel as showing a pure color image, and the method comprises: deactivating a W pixel of the display panel and changing gamma values of a R pixel, a G pixel, a B pixel from a first predetermined values to a second predetermined value; and activating the W pixel, and adjusting a gray scale image of the entire display panel to be a first predetermined value. The present invention further provides a display panel and a display. The display panel, the display and the method of the present invention can raise the display brightness of the display panel as showing the pure color image.
