Transversely arranged RGBW pixel structure, driving method thereof and display panel

Abstract

The invention discloses a bigrid-driven transversely arranged RGBW (Red Green Blue White) pixel structure, a driving method thereof and a display panel. The pixel structure comprises a plurality of pixel units in array repeated permutation, wherein each pixel unit comprises two main pixel areas, eight thin film transistors, two grid lines and four data cables; each main pixel area comprises four subsidiary pixel areas; each data cable is electrically connected with the source electrodes of the two thin film transistors, and different data cables are electrically connected with different thin film transistors; and the grid electrodes of the two thin film transistors electrically connected with the same data cable are respectively in electric connection with different grid lines. According to the embodiment of the invention, when the grid lines of the pixel structure scan pixels in different rows in the same frame, the potential polarity of a signal of each data cable is always unchanged, so that a reversion picture of the pixel points is obtained; and as the polarities of the data cables do not need to be frequently reversed, the driving frequency of the data cables is lowered, and accordingly, the power consumption of a panel is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a dual gate-driven laterally arranged RGBW pixel structure, a driving method thereof, and a display panel. Background technique [0002] In the prior art, the arrangement of four sub-pixel regions in one main pixel region of a liquid crystal display panel with double brightness is as follows: figure 1 As shown, the part included in the dotted line in the figure represents a main pixel area, and the four sub-pixel areas of R (red), G (green), B (blue), and W (white) are arranged in a "square shape", wherein each sub-pixel The area can be square or rectangular, and the mutually perpendicular two sides of each sub-pixel area are substantially parallel to the gate lines G1-G4 and data lines D1-D4 respectively, and the brightness of the white sub-pixel is the sum of the brightness of the other three sub-pixels, thus Increased the brightness of the display panel.

Problems solved by technology

[0005] In general, the power consumption of a signal is proportional to its frequency. In the prior art, the polarity of the data line is reversed every time the gate line scans a row of pixels, resulting in high power consumption of the entire panel.
