Embodiment 1
[0037] See figure 2 , figure 2 It is a schematic diagram of a pixel matrix driving device provided by an embodiment of the present invention. An embodiment of the present invention provides a pixel matrix driving device, which can improve the whitening and yellowing phenomenon in the side view of the multi-domain VA design. The pixel matrix driving device may be a display device having matrix pixel units, such as an LCD display device, a PDP display, an OLED display, and the like.
[0038] Before specifically introducing the pixel matrix driving device of this embodiment, it needs to be further explained that, for liquid crystal display devices in vertical alignment mode (VA mode), in order to obtain a better viewing angle, current liquid crystal display devices in vertical alignment mode usually Using a multi-domain approach, this display method is called "Multi-Domain Vertical AlignmentMode" (MVA mode). It is mainly realized by making protrusions or slits on the surface...
Embodiment 2
[0048] In order to better describe the data driving module, this embodiment specifically describes the driving manner of the data driving module on the basis of the foregoing embodiments.
[0049] In order to further improve the design method of multi-domain VA, which may appear whitish and yellowish when viewed from the side, in this embodiment, within one frame, for the sub-pixels driven by the same data line, along the direction of the data line, every other M sub-pixels (the first interval is every M sub-pixels, and M is an integer greater than or equal to 1), the data line alternately loads the first driving voltage and the second driving voltage to several X chip sub-pixels of the same sub-pixel , that is, if the first interval is M sub-pixels, for a certain column of sub-pixels, it is assumed that the sub-pixels are driven with a high voltage from the first time to the M-th time, and the sub-pixels are driven at a low voltage from the M+1 time to the 2M time Sub-pixels,...
Embodiment 3
[0053] In this embodiment, on the basis of the above-mentioned embodiments, the pixel matrix takes 6×6 sub-pixels, each sub-pixel is 8 chips, and is divided into two 4-chip A region and B region as an example, and the working principle of the present invention is described in detail as follows.
[0054] For a more convenient description, each sub-pixel is marked, and each sub-pixel includes several sub-pixel units, and the sub-pixel in the nth row and mth column in the pixel matrix is recorded as A nm , for example, the sub-pixel in the first row and the first column is A 11 .
[0055] For example, see Figure 4 , in one frame, sub-pixels are divided into A area and B area, and the first interval is set to be every other sub-pixel, then along the direction of the data line, for the first column of sub-pixels, at the first moment, at the A scan signal is loaded on a row of scan lines G1, and loaded to sub-pixel A with a high voltage 11 area A and area B; at the second mom...
