Abstract

The invention discloses a pixel matrix driving method. The pixel matrix includes a plurality of sub-pixels arranged in a matrix, the polarity of the data line is reversed every two columns, and the voltage applied along the direction of the data line is exchanged every N sub-pixels. polarity, and every N sub-pixels, each data line alternately applies a voltage to the I-th column and the I+2-th column sub-pixel, wherein the method includes: receiving image data, and obtaining original pixel data according to the image data ; Generate a first driving voltage and a second driving voltage according to the original pixel data; within a frame, load the first driving voltage or the second driving voltage to the pixel matrix along the data line, where I≥1 , N≥2. In addition, the invention also provides a display device. The invention prevents the pixels in the pixel matrix from being affected by the polarity, avoids problems such as crosstalk, bright and dark lines, reduces panel power consumption, lowers the temperature of the driving IC, reduces costs, and improves user experience.

Description

technical field [0001] The invention belongs to the field of pixel matrix display, and in particular relates to a pixel matrix driving method and a display device. Background technique [0002] VA-type LCD panels are widely used in current display products. At present, VA-type panels are mainly divided into two types, one is MVA (Multi-domain Vertical Alignment, multi-region vertical alignment) type, and the other is PVA (Patterned Vertical Alignment) type. Alignment, pattern vertical arrangement) type. The principle of MVA technology is to increase protrusions to form multiple viewing areas. The liquid crystal molecules are not completely vertically aligned when static, and the liquid crystal molecules are aligned horizontally after voltage is applied, so that light can pass through each layer. PVA is an image vertical adjustment technology, which directly changes the structure of the liquid crystal unit, so that the display performance can be greatly improved, and the br...
