Description
technical field [0001] The present invention relates to the field of touch technology, in particular to a touch device and a touch display device. Background technique [0002] With the development of touch display technology, touch display devices have been widely used in people's daily life. The existing embedded touch display device usually adopts a time-sharing driving mode during the working process, that is, the time required for one frame is divided into two parts: the display time and the touch time, and during the touch time, all In the above touch display device, the electrodes used as common electrodes during the display time are multiplexed as touch electrodes, so as to adapt to the development trend of thinner and lighter. [0003] However, as the resolution of the touch display device increases, the time that each frame of the screen in the touch display device can occupy becomes shorter and shorter, correspondingly, its touch time is also shorter and shorter,...
