Problems solved by technology

[0003] RGBW technology has the advantages of high brightness, high contrast, and backlight energy saving of 30% to 50% under white screens. However, due to the need to add "W" (white, white) pixels to the RGBW panel, this increases the LCD (Liquid Crystal Display, liquid crystal display) panel makers' manufacturing costs

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0038] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a driving method of a display panel and a driving device. The driving method of a display panel includes the steps: receiving an image signal to be displayed and acquiring a gray scale signal of the first pixel; according to the gray scale signal of the first pixel, obtaining a gray scale signal of the first sub pixel through calculation, and forming a gray scale signal ofthe second pixel; and driving the first pixel by means of the gray scale signal of the first pixel, and driving the first sub pixel by means of the gray scale signal of the first sub pixel. The technical scheme of the driving method of a display panel integrates an RGB panel with the RGBW technology, and can reduce the manufacturing cost of the display panel.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a method for driving a display panel and a driving device using the method for driving a display panel. Background technique [0002] RGBW technology is a new technology recently developed in the field of display technology. RGBW technology adds white sub-pixels to the original three primary colors of red / green / blue to become a four-color pixel design. Compared with RGB display technology, RGBW display technology has lower power consumption. As people's awareness of energy saving and emission reduction gradually increases, the energy-saving advantages of RGBW technology are becoming more and more obvious. [0003] RGBW technology has the advantages of high brightness, high contrast, and backlight energy saving of 30% to 50% under white screens. However, due to the need to add "W" (white, white) pixels to the RGBW panel, this increases the LCD (Liquid Crystal Displa...
