Abstract

The embodiment of the invention provides a display panel, a test method and a manufacturing method thereof, and a display device, relates to the technical field of display, and is used for narrowing the frame width of the display panel. A plurality of pixels in a display area of the display panel are divided into a plurality of pixel column groups arranged in the row direction. The pixel column group is divided into first pixel units arranged in the column direction, and two adjacent pixels in at least one first pixel unit in the column direction are different in color. The test unit is positioned on one side, far away from the display area, of the multiplexer unit. One test unit is electrically connected with one pixel column group through one multiplexer. The test unit comprises a plurality of second switches of which the number is greater than or equal to the number of colors of pixels in the first pixel unit. For the same first pixel unit, the second switch is electrically connected between one first switch and one test signal line. The second switches are sequentially turned on, and test signals are sequentially transmitted to each pixel in the first pixel unit.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method, a testing method and a display device. 【Background technique】 [0002] In the production process of the display panel, before the display panel is bound to the driver chip IC, it is usually necessary to perform a visual test (Visual Test, hereinafter referred to as VT test) on the display panel through a shorting bar to detect whether the display panel is There are defects, so as to avoid making defective products enter the next IC binding process. [0003] At present, when VT testing is performed on a display panel, the shorting bar used for testing is usually directly connected to the pixel circuit located in the display area. A demux is usually provided on the side of the shorting bar away from the display area, resulting in a larger size of the lower frame of the display panel, which is not conducive to the narrow frame des...
