Abstract

The invention discloses a display unit, which comprises a plurality of pixel cells, a plurality of gate lines, a reading line and a plurality of touch control units. The gate lines are used for determining whether to open the pixel cells; and the touch control units are respectively and electrically coupled to the reading line and corresponding gate lines, and comprise switch elements. When one of the touch control units is touched, the switch element of the touched touch control unit is conducted to couple the waveform of the gate line corresponding to the touched touch control unit to the reading line, and the time sequence of the waveform of the reading line is utilized for judging the position of the touched touch control unit. The invention also provides a touch control detection method, which couples the waveform of the gate line to the reading line and judges the position, quantity and / or touch time span of the touched touch control unit by using the waveform of the reading line.

Description

technical field [0001] The invention relates to a display device capable of performing a touch screen function and a touch detection method. Background technique [0002] The touch screen provides a new interface for human-computer interaction, which is more intuitive and humane in use. The traditional touch screen technology detects signals through an additional indium tin oxide (ITO) module, which has the disadvantages of high cost, low contrast, and increased module thickness. In order to solve the above problems, many countermeasures have been proposed to directly integrate the touch function into the panel manufacturing of the display device. Among them, the press type touch screen has the advantages of not being affected by ambient light and being in line with human intuition. For example, the signal is obtained by detecting the common voltage (Vcom) potential transmitted when the thin film transistor array (TFT Array) substrate is in contact with the color filter (C...
