Problems solved by technology

[0005] However, the problem with the above method is that it needs to double the number of metal wiring and driving devices to drive the sub-pixels, so that the light-transmitting opening area is sacrificed, which affects the light transmittance of the panel, and the cost is also higher.

Abstract

The invention discloses a driving method and equipment of a display panel. In the present invention, the scanning of at least two rows of pixel units is used as the driving cycle, and the common electrodes of the sub-pixels in the pixel units of the preset row are respectively driven with different preset voltages in the current driving cycle, without adding a double the number of metal wires and driving devices to drive sub-pixels to achieve the purpose of cost saving, and when the preset voltage is positive and negative driving voltages, the high-voltage sub-pixels and low-voltage sub-pixels in the pixel unit The pixel is driven by a preset driving method, so that the sub-pixels in the pixel unit are arranged in a way of crossing high and low voltages, thereby achieving the purpose of solving the angular deviation of viewing angle.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to a method and device for driving a display panel. Background technique [0002] Most large-size liquid crystal display panels adopt a negative vertical alignment (Vertical Alignment, VA) type or an in-plane switching (In Panel Switching, IPS) type. Compared with IPS liquid crystal technology, VA liquid crystal technology has the advantages of higher production efficiency and lower manufacturing cost, but compared with IPS liquid crystal technology, it has more obvious defects in optical properties. LCD panels suffer from color casts. [0003] When displaying an image, ideally, the brightness of a pixel should change linearly with the change of the voltage, so that the driving voltage of the pixel can accurately represent the gray scale of the pixel and reflect it through the brightness. Such as Figure 1a As shown, when VA-type liquid crystal technology is used, when vi...
