Problems solved by technology

[0005] However, although increasing the cross-sectional width of the gate lines or data lines can alleviate the signal delay, on the premise that the area of ​​the array substrate is relatively fixed, increasing the cross-sectional width of the gate lines or data lines will reduce the effective display area of ​​the array substrate, resulting in The aperture ratio of TFT-LCD decreases

Abstract

The invention provides a driving method and a driving circuit of a display device and the display device and relates to the technical field of displays in order to increase the aperture ratio. The display device comprises an array substrate, at least one grid electrode driving circuit and at least one source electrode driving circuit, wherein the array substrate comprises a plurality of grid lines and a plurality of data lines. The method includes the steps that a display area of the array substrate is divided into at least two sub-areas in the direction of the data lines, and each sub-area comprises at least one grid line; corresponding charging time is set for the grid lines of the sub-areas, the average charging time of the grid lines in the sub-areas tends to be prolonged along with increase of vertical distances between the sub-areas and areas where the source electrode driving circuits at the specific ends of the data lines are located; the grid lines of the sub-areas are sequentially charged for the corresponding period of time. The driving method and the driving circuit of the display device and the display device are mainly used in the display technology.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a driving method, a driving circuit and a display device of a display device. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. For TFT-LCD, the structure and manufacturing process of the array substrate have an important impact on product performance. Among them, parameters such as pixel charging rate and aperture ratio are important parameters to measure product performance, but the loading (RCloading) of the array substrate is an important factor affecting the charging rate and aperture ratio. [0003] As the resolution of the TFT-LCD increases, the PPI (Pixelperinch) increases, and the number of pixels in the array substrate of the same size increases, resulting in an increase in the load...
