Abstract

The present invention discloses a touch panel and an operation method thereof. The Touch panel comprises a touch circuit, a substrate, a first metal layer, at least a light emitting diode, and a second metal layer, wherein the touch circuit is used for providing a touch scanning signal, the first metal layer is disposed at a side of the substrate, the light emitting diode is provided with a first end and a second end, the first end of the light emitting diode is coupled to the first metal layer in an electrical manner; the second metal layer is coupled to the second end of the light emitting diode and the touch circuit, and the touch control circuit transfers a touch control signal to the second metal layer; the first metal layer and the second metal layer are disposed at two opposite sides of the light emitting diode, and the first metal layer and the second metal layer are used for transmitting the current that goes through the light emitting diode.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a display panel with touch function. Background technique [0002] Today's electronic systems (such as notebook computers, mobile phones, and tablets) have many different types of input devices, such as buttons, mice, trackballs, and touch screens, etc., which can provide users with operating and controlling the system. In recent years, due to the reduction of the manufacturing cost of the touch screen and the more intuitive man-machine interface of the touch screen, the touch screen gradually replaces the traditional input device. [0003] Based on the operating principle of touch screen, touch screen can be mainly divided into resistive type, capacitive type and acoustic wave type. Among them, in the resistive touch screen, the control circuit senses the potential change between the internal conductive film and the glass substrate to locate the touch position; in the capacitive t...
