Problems solved by technology
[0004] However, for the PSVA type liquid crystal panel, because the optical path difference of the liquid crystal in the side view direction is larger than that in the front view direction, it will appear white when viewed from the side.
Moreover, the power consumption and temperature of the 1+N Line Inversion driving method are relatively large, and due to the RC (Resistance Capacitance, resistance / capacitance) delay effect, the problem of insufficient charging of the pixels will occur, resulting in horizontal equidistant on the LCD panel. Horizontal stripes

The invention relates to a pixel matrix driving device, a pixel matrix driving method and a display thereof. The pixel matrix driving device includes a pixel matrix, a timing controller and a driving module. The column sub-pixels have different polarity inversion positions; the timing controller is used to obtain the initial pixel value, and obtain the first grayscale value and the second grayscale value according to the initial pixel value; the driving module is used to obtain the first grayscale value according to the first grayscale value. The first loading voltage is obtained from the level value, the second loading voltage is obtained according to the second gray level value, and the first loading voltage and the second loading voltage are loaded to the pixel matrix. In the present invention, the polarity inversion positions of the sub-pixels in two adjacent columns are different, and the sub-pixels in a certain row and a certain column of sub-pixels are alternately loaded with the first loading voltage or the second loading voltage to the sub-pixels. The horizontal equidistant stripes are improved and the whitening phenomenon that occurs when the display panel is viewed sideways is improved, so that both front view and side view have good display quality.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a pixel matrix driving device, a pixel matrix driving method and a display thereof. Background technique [0002] With the development of display technology, liquid crystal display (LCD) has gradually replaced cathode ray tube (CRT) display devices due to its advantages of lightness, thinness and low radiation. Information terminals such as navigation devices and e-books have become the most common display devices. [0003] As the display specifications of liquid crystal displays continue to develop toward large sizes, the market demands more and more features such as high contrast, fast response and wide viewing angle for the performance of liquid crystal displays. In order to overcome the viewing angle problem of large-sized liquid crystal displays, the wide viewing angle technology of liquid crystal displays must be constantly improved and made breakthroughs.
