Embodiment 1
[0033] Based on the above ideas, an embodiment of the present application provides a display driving method, which is used to drive a display with a four-color sub-pixel structure whose resolution includes the second resolution.
[0034] refer to figure 1 , the driver method includes:
[0035] Step S11: providing first display data, the first display data includes three-color sub-pixel data of a first resolution. Wherein, the first display data is baseband information.
[0036] In this embodiment, the first display data includes RGB three-color sub-image data, but is not limited to the RGB three-color sub-image data. The first display data is RGB three-color sub-image data so that it can be used to drive a display with an RGB three-color sub-pixel structure and a resolution including the first resolution. Each pixel unit of the display is composed of red R-type pixels, green The G sub-pixel and the blue B sub-pixel are composed of three sub-pixels.
[0037] The first displ...
Embodiment 2
[0053] Based on the driving method described in the above embodiments, another embodiment of the present invention further provides a driving circuit for a display, the display is a display with a four-color sub-pixel structure whose resolution includes a second resolution.
[0054] refer to image 3 , the drive circuit includes: a first circuit 21 , a second circuit 22 and a third circuit 23 . Wherein, the first circuit 21 is connected to the third circuit 23 through the second circuit 22 .
[0055] The first circuit 21 is used for providing first display data, and the first display data includes three-color sub-pixel data with a first resolution. The output terminal of the first circuit 21 is used to output the first display data.
[0056] The input terminal of the second circuit 22 is connected with the output terminal of the first circuit 21 . The second circuit 22 is used for converting the first display data into second display data, and the second display data includ...

Abstract
The invention discloses a driving method of a displayer, a driving circuit of the displayer and a display device. The displayer is of a four-color sub-pixel structure, and the resolutions of the displayer include the second resolution. The driving method comprises the steps that first display data are provided, wherein the first display data include three-color sub-pixel data of the first resolution; the first display data are converted into second display data, wherein the second display data include four-color sub-pixel data of the first resolution; the second display data are converted into third display data, wherein the third display data include four-color sub-pixel data of the second resolution, and the second resolution is larger than the first resolution. According to the driving method,the driving circuit and the display device, power consumption in the driving control process of the displayer is reduced, and the cost is reduced.
Description
technical field [0001] The present invention relates to the display field, and more specifically, relates to a display driving method, a driving circuit thereof, and a display device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Liquid crystal display devices have become mainstream display devices due to their advantages such as good driving performance, low power consumption, good image display quality, and large-screen display. The liquid crystal display device with RGBW four-color sub-pixel stru...
