Abstract

The invention discloses a display panel, a touch test method and electronic equipment. The display panel comprises a substrate, a touch test terminal, a multiplexing circuit, a touch unit and a touch display chip, according to the display panel, before the touch display chip is bound, the number of wires, connected to the touch test terminal, of the touch unit is reduced through the multiplexing circuit, so that a touch test is smoothly carried out; and meanwhile, the use number of the touch test terminals is reduced, and the occupied space of the frame can be saved.

Description

technical field [0001] The present application relates to the technical field of touch display, in particular to a display panel, a touch test method and electronic equipment. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display has the advantages of active light emission, large viewing angle, wide color gamut, high brightness, fast response speed, low power consumption and flexible structure, etc., and it is more and more popular in the market. Welcome to become the mainstream of display technology. [0003] At present, most of the Direct On-Cell Touch (DOT) on the screen adopts a mutual capacitance touch screen design scheme, and its touch chip (TIC, Touch IC) and source driver chip (Drive IC) are independent of each other. Two ICs (Integrated Circuit, integrated circuit), usually DIC is located on the flexible substrate of AMOLED (Active-matrix organic light-emitting diode, active matrix organic light-emitting diode) typ...
