Polarity inversion driving method and polarity inversion driving circuit

Abstract

A polarity-reversal driving method comprises: when a picture is displayed, sequentially connecting pixel units corresponding to a first gate line by using a first gate line, loading first data voltage signals to the connected pixel units by using odd-numbered columns of data lines, and loading second data voltage signals to the connected pixel units by using even-numbered columns of data lines, polarities of the first data voltage signals being opposite to those of the second data voltage signals; and sequentially connecting pixel units corresponding to a second gate line by using a second gate line, loading third data voltage signals to the connected pixel units by using odd-numbered columns of data lines, and loading fourth data voltage signals to the connected pixel units by using even-numbered columns of data lines, polarities of the third data voltage signals being opposite to those of the fourth data voltage signals. The polarity-reversal driving method reduces the number of times of the polarity reversal, thereby reducing the power consumption of a display panel. Also disclosed is a polarity-reversal driving circuit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarity inversion driving method and a polarity inversion driving circuit. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD for short) is a mainstream product in the liquid crystal display. Array substrates are important components of liquid crystal displays. The array substrate includes: a base substrate and gate lines and data lines formed on the base substrate, and the gate lines and data lines define pixel units. figure 1 It is a schematic diagram of a pixel unit array of an array substrate in the prior art, such as figure 1 As shown, the gate lines G1 to G7 and the data lines D1 to D7 define a plurality of pixel units, and the gate lines G1 to G7 are all connected to the timing controller. The timing controller...
