Problems solved by technology
[0003] For TFT-LCD, the scanning lines and data lines control the charging of pixels through thin film transistors. When charging, the load of data lines and scanning lines has a decisive impact on the charging efficiency of pixels, which determines whether the charging of pixels is sufficient. Due to the parasitic capacitance and resistance of the data line and the scanning line, the load is large, which affects the charging effect. Therefore, there is a problem of insufficient pixel charging.

The invention discloses a display panel and a display device, and the display panel comprises a common line, a plurality of data lines and a plurality of scanning lines are crisscrossed to form a plurality of pixel regions, and each pixel region is correspondingly provided with a sub-common line; the number of the data lines is m, and the number of the scanning lines is n; each horizontal line is arranged in a manner of being crossed with the corresponding data line, and two adjacent sub common lines in the direction of the scanning line are communicated; in the plurality of vertical wires, each vertical wire and the corresponding scanning wire are arranged in a crossed manner, and the two adjacent sub common wires in the direction of the data wire are communicated; the number of the horizontal wires is smaller than or equal to m; the number of the vertical wires is smaller than or equal to n-1; and all the sub common lines are communicated to form the common line through the horizontal lines and the vertical lines, and the delay of the data lines and the scanning lines is reduced by reducing the number of the horizontal lines and the vertical lines.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] TFT-LCD (Thin Film Transisitor Liquid Crystal Display) is a thin film field effect transistor LCD, which is one of the active matrix liquid crystal displays. It has excellent performance, good mass production characteristics, high degree of automation, low cost of raw materials, and development Wide space, has become the mainstream product in the new century; [0003] For TFT-LCD, the scanning lines and data lines control the charging of pixels through thin film transistors. When charging, the load of data lines and scanning lines has a decisive impact on the charging efficiency of pixels, which determines whether the charging of pixels is sufficient. The data line and the scan line are heavily loaded due to factors such as parasitic capacitance and resistance, which affects the charging effect. There...
