Embodiment Construction

[0027] figure 1 It is a schematic flowchart of a display driving method according to an embodiment of the present invention. Please refer to figure 1 , the driving method of the display in this embodiment is suitable for driving a display with red sub-pixels, green sub-pixels, blue sub-pixels and white sub-pixels, when a red-green-blue image data is input to the display, the display can display A maximum color gamut. At this point, the maximum color gamut that the display can display is determined, as in step S100. After determining the maximum color gamut that can be displayed by the display (as shown in step S100 ), then select a target color gamut within the maximum displayable color gamut of the display, as in step S110 . Afterwards, the red-green-blue image data is converted into a red-green-blue-white image data, so that the display can display the target color gamut, as in step S120. Finally, the red-green-blue-white image data is input to the display to drive the d...

Abstract

A drive method of a display is suitable for driving the display having red secondary pixel, green secondary pixel, blue secondary pixel and white secondary pixel, when inputting a red-green-blue image data to the display, the display can display a max color area, the drive method of the display comprises: selecting a target color area in the max color area displayed by the display; converting thered-green-blue image data into the red-green-blue-white image data in order to display the target color area by the display; inputting the red-green-blue-white image data into the display to drive the display. The drive method can effectively increase the image brightness and improve the condition that the display image is not continuous under the condition without losing the color saturation greatly.

Description

technical field [0001] The present invention relates to a display driving method, and in particular to a display driving method for converting red-green-blue image data (R-G-B image data) into red-green-blue-white image data (R-G-B-W image data). Background technique [0002] Liquid crystal displays (Liquid Crystal Displays, LCDs) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of displays. In order to meet the needs of users, various manufacturers are committed to the development of high color reproduction (color reproduction) technology, and the development of high color reproduction technology has nothing to do with the color saturation (colorsaturation) of the backlight source of the liquid crystal display and the color filter film. closely related. [0003] In order to allow the display to have better brightness performance, a display with four sub-...
