Problems solved by technology

[0008] However, when the user applies an external force to the touch panel 1, since the common electrode 15 is a one-piece structure, the local recessed area may include other non-touch positions in addition to the touch position.
At this time, it may cause misjudgment of the touch position by the touch panel 1

Abstract

The invention discloses a touch panel which is provided a thin film transistor substrate and a color filter substrate, wherein the thin film transistor substrate is arranged opposite to the color filter substrate. A public electrode is arranged at one side of the color filter substrate near the thin film transistor substrate and is provided with a plurality of opening parts. The touch panel comprises an induction reading loop, a touch unit and at least one pixel unit, wherein the pixel unit is arranged near the touch unit; the touch unit is provided with a plurality of parallel first induction lines and is arranged at one side of the thin film transistor substrate near the color filter substrate, wherein each first induction line is arranged opposite to each corresponding opening part; and the pixel unit is provided with a pixel electrode and is arranged on the thin film transistor substrate, and the electric property of the pixel electrode is electrically controlled by a scan line and a data line.

Description

technical field [0001] The invention relates to a touch panel. Background technique [0002] With the continuous advancement of science and technology, various information devices are constantly being introduced. Wherein, as far as the data input device is concerned, in addition to generally inputting data with a keyboard or a mouse, using touch technology to input data is also another option for inputting data. In addition to vision and hearing, people also have a sense of touch, and with the continuous update and breakthrough of sensor technology, touch sensors have become another choice for people to communicate with information equipment. [0003] On the other hand, traditional computer input interfaces (such as keyboards or mice) have a certain degree of difficulty in operation for people who are not familiar with computers, and have become one of the obstacles to the popularization of computers. In order to provide a more intuitive operating device, recently, the ind...
