Abstract

The invention provides a source electrode drive device and method for a liquid crystal panel with the unequal row drive widths. An input signal decoding control unit electrically connected with multiple data signal output channels is arranged, start address signals and stop address signals of the data signal output channels are coded in the packaging process of data signal transmission and transmitted to the input signal decoding control unit, the input signal decoding control unit controls the number of the started data signal output channels according to the received start address signals and the received stop address signals of the data signal output channels so as to adjust the row drive width in the scanning process every time, the row drive width of each row can be dynamically adjusted in the scanning process, the data signals are only transmitted in pixels needing to be displayed in each row, the device and method are suitable for non-rectangular display, and the output power consumption of the liquid crystal panel is reduced. The source electrode drive device for the liquid crystal panel with the unequal row drive widths is designed on the basis of an existing drive framework and the structure is simple.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a source driver and a source drive method of a liquid crystal panel with unequal row drive widths. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Active Matrix Liquid Crystal Display (AMLCD) is the most commonly used display device at present. The active matrix liquid crystal display includes a plurality of scanning lines extending in the horizontal direction and data lines extending in the vertical direction. The crossing of the wire and the multiple data lines forms a plurality of pixel areas, each pixel area is provided with a pixel,...
