Problems solved by technology

Therefore, in the case of multi-finger or multi-touch, the front-end circuit may falsely report ghost points (Ghost Points), and cannot determine the actual coordinate point of the touch
Therefore, with the current technology, the self-capacitance sensing method is not suitable for the functional requirements of real multi-touch

Abstract

The invention provides an integrated touch control display panel comprising a plurality of sub pixel units, a first touch control unit, a second touch control unit, at least two first touch control wires, at least two second touch control wires, at least two third touch control wires, and at least two fourth touch control wire. Each sub pixel unit at least comprises a pixel electrode. The first touch control unit comprises a first transmitting electrode and a first sensing electrode. The first transmitting electrode at least includes a first sub electrode and a plurality of second sub electrodes which are staggered with the first sub electrode. The first sensing electrode at least includes a plurality of third sub electrodes, and is arranged in a first accommodating area. The second touch control unit comprises a second transmitting electrode and a second sensing electrode. The second transmitting electrode at least includes a fourth sub electrode and a plurality of fifth sub electrodes which are staggered with the fourth sub electrode.

Description

technical field [0001] The present invention relates to a display panel, in particular to a display panel integrated with touch. Background technique [0002] The capacitive touch screen combined with the user interface for gesture recognition leads the trend of introducing touch screen functions into electronic products. The operating principle of the general projected capacitive touch panel mainly utilizes the capacitive induction formed by contact between the touch electrodes on the touch panel and human fingers or conductive objects, and converts it into an image that can be interpreted by the operating system through back-end calculations. coordinate data. [0003] In order to realize coordinate interpretation, in the structure of the projected capacitive touch panel, there are usually single-layer or double-layer touch electrodes arranged in a staggered manner in different axes (eg defined as X-axis and Y-axis). These touch electrodes are then electrically connected ...
