Abstract

The invention relates to a pixel driving circuit, a driving method and a display device. The driving circuit comprises a pixel array, data lines and scanning lines. The pixel array comprises multiple pixel units, and each of the pixel units comprises four sub pixels in different colors. The sub pixels are arranged in a way that the polarity of one sub pixel is opposite to the polarity of an adjacent sub pixel. The data lines and the scanning lines are orthogonally configured in the pixel array. Two scanning lines are arranged on each line of the pixel units and two data lines are arranged on each row of the pixel units. When each data line passes through one line of the pixel unit, two nearest sub pixels with the same polarity are connected, the polarities of all the sub pixels which are connected on the same data line in the row direction are the same and the polarities of adjacent sub pixels connected with the corresponding data line are opposite. By use of the pixel driving circuit, polarity switching is not required in one frame of a source electrode voltage signal, so power consumption of the whole panel and the temperature of a source integrated circuit are reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a driving method and a display device. Background technique [0002] With the continuous improvement of display resolution and scan rate, in consideration of reducing the number of source ICs used, many products adopt pixel wiring design based on half source driving (HSD) architecture in panel design . [0003] However, for the conventional HSD pixel wiring design, the source voltage (source voltage) signal needs to be converted in polarity within one frame, which significantly increases the power consumption of the source IC. In addition, the temperature of the IC also rises during display on the image surface, resulting in deterioration of reliability and quality. Contents of the invention [0004] Based on this, it is necessary to provide a pixel driving circuit, a driving method and a display device for the problem that the source voltage...
