Problems solved by technology

However, this method requires a lot of wiring, and M*N touch signal readout lines are required, especially for large-size screens, the integration method and signal reading are very difficult.
[0010] Therefore, although the self-capacitance touch has high precision and can be operated with wet hands, the inability to multi-touch due to ghost points and the need for more touch signal readout lines seriously restrict the further development of self-capacitance touch technology. and application

Abstract

The invention discloses a touch control structure and a touch control display panel, the touch control structure comprises a plurality of touch control units, a plurality of touch control row selection lines and a plurality of touch control column read-out lines, one column of touch control units is configured with one touch control column read-out line, and needed touch control signals can be read only through N touch control column read-out lines; meanwhile, one touch control row selection line is electrically connected with one row of touch control units, required touch control signals can be read out one row by one row, and ghost points are avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch structure and a touch display panel. Background technique [0002] The integrated touch sensing performance of the display panel can bring more diverse and more convenient user experiences. Projected capacitive touch screens are mainly used in the market today, which are divided into self-capacitive touch screens and mutual-capacitive touch screens. [0003] Among them, such as figure 1 and figure 2 As shown, the self-capacitance touch screen includes a plurality of touch electrodes 1, and each touch electrode 1 has a capacitance CP to the ground. When the human hand approaches the corresponding touch electrode 1, the gap between the human hand and the touch electrode 1 The sensing capacitance CF will change, so that the touch position can be determined. [0004] Such as image 3 and Figure 4 As shown, the mutual capacitance touch screen includes a plura...
