Pixel matrix driving device, pixel matrix driving method and display thereof

Abstract

The invention relates to a pixel matrix driving device, a pixel matrix driving method and a display thereof. The pixel matrix driving device comprises a pixel matrix, a time schedule controller and adriving module; the pixel matrix comprises a plurality of sub-pixels, and different polarity inversion positions are arranged between the i-th column of sub-pixels and the (i + 1)-th column of sub-pixels; the time sequence controller is used for obtaining an initial pixel value and obtaining a first gray-scale value and a second gray-scale value according to the initial pixel value; and the driving module is used for obtaining a first loading voltage according to the first gray-scale value, obtaining a second loading voltage according to the second gray-scale value, and loading the first loading voltage and the second loading voltage to the pixel matrix. According to the invention, the polarity reversal positions of two adjacent columns of sub-pixels are different; and the voltage is alternately loaded to the sub-pixels by the first loading voltage or the second loading voltage in a certain row of sub-pixels and a certain column of sub-pixels, so the horizontal equidistant cross grainscan be improved, the whitening phenomenon of the display panel in side view can be improved, and the display panel has good display quality in front view and side view.

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 for short) has gradually replaced cathode ray tube (Cathode Ray Tube, CRT for short) display devices due to its advantages of lightness, thinness and low radiation. It has become the most common display device in information terminals such as navigation devices and e-books. [0003] As the display specifications of liquid crystal displays continue to develop towards larger sizes, the market's performance requirements for liquid crystal displays are increasingly focused on characteristics such as high contrast, fast response, and wide viewing angles. In order to overcome the viewing angle problem of large-size liquid crystal displays, the wide viewing angle technology of liquid crysta...

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.
