Problems solved by technology
[0004] Among them, at the edge of the display panel, the display pixel and the dummy pixel share a data line for charging, but in order to ensure that the dummy pixel is not displayed, the data line connected to the dummy pixel is usually disconnected.
In such a case, the display pixels and dummy pixels that originally share a data line for charging will become that the data line is only used to charge the corresponding display pixels, resulting in a smaller load on the data line and making the charging of the display pixels at the edge higher resolution than other pixels, resulting in poor display effects at the edge of the display panel, such as bright lines at the edge of the display panel

The application provides an array substrate and a display panel. The array substrate includes a display area and a non-display area adjacent to the display area; the array substrate includes a plurality of scanning lines extending in the horizontal direction, a plurality of data lines extending in the vertical direction, and a plurality of pixel units; the pixel unit includes a display pixel unit and dummy pixel units; the data lines include a plurality of first data lines and at least one second data line, and the second data lines are located between the display pixel units and the dummy pixel units; wherein, the projection of the second data lines is at least partially The dummy pixel electrodes overlap to form overlapping regions. This application changes the design method of the data line between the display pixel unit and the dummy pixel unit on the array substrate, thereby reducing the charging rate of the display pixel unit corresponding to the data line, ensuring that the charging rate is equivalent to that of other pixel units, thereby improving the display panel. The phenomenon that the display effect at the edge is not good.
Description
technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate and a display panel. Background technique [0002] Among flat-panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) panels have the characteristics of small size, low radiation and relatively low manufacturing cost, and are widely used in electronic products such as mobile phones, computers, and televisions. Applications. [0003] In order to ensure the etching uniformity of the display pixels located at the edge of the display area during the manufacturing process of the liquid crystal display, several rows or columns of dummy pixels are usually arranged on the edge of the display area of the array substrate, so that the edge of the display area has dummy thin film transistors and dummy pixel electrodes ( dummy pixel). [0004] Wherein, at the edge of the display panel, the display pixel and the dummy pixel share a dat...
