Abstract

The invention discloses a touch panel, a manufacturing method thereof and a display device. A multiplex cathode of the touch panel is used as a touch electrode, and the cathodes distributed in a matrix mode are connected with a touch chip through touch electrode wires so as to achieve a touch function, wherein the first lead part of the touch electrode wire covers the surface of the first supporting column; so that the cathode can be directly connected with the first lead part; the first lead part can be connected with the touch chip through the second lead part, so that the touch function canbe realized. Compared with the prior art, the touch control electrodes achieve the touch control function through the touch control wires located on the same layer of the peripheries of the touch control electrodes, touch control blind areas can be avoided, meanwhile, a plurality of cathodes which are arranged in a matrix mode and consistent in size are multiplexed as the touch control electrodes, and the problem that due to the fact that the touch control electrodes are not uniform in size, the touch control uniformity is poor is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch panel, a manufacturing method thereof and a display device. Background technique [0002] With the advancement of display technology, organic light-emitting display (OLED, Organic Light Emitting Diode) is one of the hot spots in the field of flat panel display research today, and more and more active matrix organic light-emitting diodes (AMOLED, Active Matrix Organic Light Emitting Diode) Display panels have entered the market. Compared with traditional thin film transistor liquid crystal display panels (TFT LCD, Thin Film Transistor Liquid Crystal Display), AMOLED has faster response speed, higher contrast ratio and wider viewing angle. [0003] At present, OLEDs have begun to replace traditional LCD displays in display fields such as mobile phones, PDAs, and digital cameras. At the same time, with the progress of the display technology, the in-cell touch techn...
