Abstract

The invention discloses a touch panel and a display device, the touch panel and the display device comprise a display area, the touch panel comprises a plurality of touch blocks, wherein one side of each column of touch blocks is provided with a corresponding blind area, and the plurality of touch blocks and the plurality of blind areas are all located in the display area; and a test circuit comprising test lines, wherein the test lines are located in the corresponding blind area; according to the scheme, the test lines can be prevented from crossing the touch blocks, so that the structural difference between part of the touch blocks and other touch blocks is avoided, and the touch performance of the touch panel and the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of display panel manufacturing technology, in particular to a touch panel and a display device. Background technique [0002] In the under-display camera technology, laser cutting is usually used to form a through hole to place the camera. Laser cutting is prone to cracks and leads to circuit breakage, so the detection circuit is particularly important. [0003] Among them, since the mutual capacitive touch panel includes a bridging layer arranged on a different layer from the touch electrodes, the detection circuit can be arranged on the same layer as the bridging layer to avoid straddling the touch electrodes; however, a large number of touch electrodes in the self-capacitive touch panel The control blocks are all set on the same layer, and the detection circuit and a large number of touch blocks are set on the same layer across some touch blocks, resulting...
