Abstract

The invention relates to an embedded self-capacitance touch liquid crystal display device and a data processor and a screen body thereof. The embedded self-capacitance touch liquid crystal display device comprises reuse electrodes, touch controlled switch devices and data processing chips. The touch controlled switch devices are divided into N touch sets. When the data processing chips are used for conducting touch detection and controlling, and after touch controlled ends of the touch controlled switch devices of all touch sets receive connected touch control signals according to touch time slices, all reuse electrodes in the same touch set are electrically connected with a touch module in one touch time slice. Through the scheme of electrode reuse and pin reuse, the pins of the data processing chips of the embedded self-capacitance touch liquid crystal display device are reduced, then the number of the contact bump of a touch detection channel is reduced, the area of the chips is reduced, and the boundary range of a touch display panel is reduced.

Description

technical field [0001] The invention relates to a circuit connection structure and a circuit structure for reducing connection pins of a data processing chip, in particular to a circuit connection structure of an embedded touch screen and a circuit structure for reducing the connection pins of a data processing chip. Background technique [0002] The prior art embedded self-capacitance touch LCD display, also known as In-Cell self-capacitance touch LCD, includes a liquid crystal display body and a data processing chip, and detects changes in self-capacitance through electrodes covering the touch area of ​​the screen, thereby Determine whether a touch to the screen has occurred, and determine the location of the touch. Regardless of whether the data processing chip solution of the In-Cell self-capacitance touch LCD adopts the integrated drive and control Integrated Drive & Controller solution referred to as IDC, or adopts the Touch and Display Drive Integration solution refer...
