Problems solved by technology

[0005] The above-mentioned capacitive embedded touch screen that multiplexes the common electrode layer generally adopts a common square graphic design when dividing the common electrode layer, that is, as figure 1 As shown, the touch driving electrode Tx and the touch sensing electrode Rx are in a square shape, and the mutual capacitance generated between the touch sensing electrode Rx and the touch driving electrode Tx is small, so that the electric field of the human body has little effect on the mutual capacitance change. The impact is small. When the human body touches the touch screen, the power signal coupled by the touch sensing electrode changes little, making the sensitivity of the touch screen low.

Abstract

The invention discloses a capacitance type touch module, a capacitance type in cell touch panel and a display device, and adopts the scheme that a whole surface-connected public electrode layer in an array substrate is divided to form touch inducting electrodes and touch driving electrodes which are insulated with one another, and the touch inducting electrodes and touch driving electrodes are driven in a time-shared manner, so that a touch function and a display function are achieved; each of touch inducting electrodes comprises a plurality of touch inducting subelectrodes, each of touch driving electrodes comprises a plurality of touch driving subelectrodes, and the opposite side edges of the adjacent touch inducting subelectrode and the touch driving subelectrode are fold lines, so that the opposite area between the adjacent touch driving electrode and the touch inducting subelectrode is increased, the mutual capacitance between the touch driving electrodes and the touch inducting subelectrodes in a unit area is increased, and further the sensitivity of the touch panel during touch is improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive touch module, a capacitive embedded touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread throughout people's lives. At present, touch screens can be divided into three types according to their structure: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel. Among them, the plug-in touch screen is produced separately from the touch screen and Liquid Crystal Display (LCD), and then bonded together to form a touch-enabled LCD screen. The plug-in touch screen has high production costs and low light transmittance. Low, thick modules and other shortcomings. The embedded touch screen embeds the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and grea...
