Driving method and driving circuit for liquid crystal display, and liquid crystal display

Abstract

The embodiment of the invention provides a driving method and a driving circuit for a liquid crystal display, and the liquid crystal display. The method comprises the following steps of: dividing the time of any frame into two operation time buckets in a line inversion or dot inversion driving mode; and in one operation time bucket, sequentially enabling odd-line scanning lines, and writing odd-line data signals into odd-line pixels, and in the other operation time bucket, sequentially enabling even-line scanning lines, and writing even-line data signals into even-line pixels. The odd-line scanning lines and the even-line scanning lines of the liquid crystal display are driven respectively, the driving of each time is finished within 1 / 2 of the time length of one frame, and the load capacitance of the pixels is not required to be converted from positive voltage to negative voltage within one operation time bucket, and is most just converted from the positive voltage or the negative voltage to reference level, so that reduction in the power consumption of the data logic of the liquid crystal display can be learned according to a power consumption formula.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a driving method, a driving circuit and a liquid crystal display for a liquid crystal display. Background technique [0002] Power consumption is an important performance index of liquid crystal displays, and an important component of it is the logic power consumption of data signals. [0003] In liquid crystal displays, common storage capacitors include gate storage capacitors (Cs on gate) and common electrode storage capacitors (Cs on common). The storage capacitor is routed using the common electrode. Each thin-film transistor (TFT) is connected to the storage capacitor Cst, which represents a display point. A basic display unit (pixel) needs three such points to represent the three primary colors of red (R), green (G), and blue (B). ; A thin film transistor liquid crystal display (TFT LCD) with a resolution of 1024×768 needs 1024×768×3 such points in total. With the wav...
