The invention discloses a touch display panel. The touch display panel comprises a first electrode and a second electrode which are arranged oppositely; a conductive layer is arranged between the first electrode and the second electrode; the conductive layer and the first electrode, and the conductive layer and the second electrode are insulated mutually; pressure detection is carried out according to capacitance variable quantity of a series capacitor which consists of the first electrode, the conductive layer and the second electrode; the conductive layer comprises a plurality of conductive blocks in array distribution; the touch display panel comprises a first region and a second region which is arranged around the first region; and the area of the conductive blocks in the first region is smaller than that of the conductive blocks in the second region. The invention provides a driving method for driving the touch display panel provided by the invention. When the touch display panel provided by the invention suffers from the same pressure at different positions, pressure signal semaphore of the same magnitude can be detected, so that uniformity of touch detection is improved; and in addition, the pressure signal semaphore of the overall touch display panel can be improved, so that the user experience is enhanced.
Description
technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display panel and a driving method for the touch display panel. Background technique [0002] The touch display panel has the advantages of display and position touch detection, easy to use, and good human-computer communication experience, so it is widely favored by the market. With the development of touch technology, there is now a relatively new touch technology - pressure-sensitive touch technology, which is slowly attracting attention. When the touch display panel combined with the pressure-sensitive touch technology is subjected to external pressure, it can feed back different information according to different pressures, thereby providing more user experience. However, in the prior art, when the touch display panel is pressed by the same pressure from a finger, the deformation of the glass at the center and edge of the touch display panel is inconsistent, ...
