Abstract:
1. A display device switchable between a display mode and a touch mode, the device comprising: at least a first and second drive region, each having a plurality of display pixels having storage capacitors connected together along first and second, different directions by first and second common voltage lines; a sense region positioned between the first and second drive regions, the sense region having a plurality of display pixels having storage capacitors connected together along the first and second directions by third and fourth common voltage lines, the first common voltage lines of the first drive region electrically bypassing the sense region to couple to the first common voltage lines of the second drive region; each display pixel of the sense region having a data line configured to transmit a display data signal and a sense line configured to transmit a touch signal, the sense line coupled to a touch circuit, and the sense line being distinct from the data line; a switch configured to switch the data line between a first configuration associated with a display mode and a second configuration associated with a touch mode; and wherein in the second configuration, the data lines of at least some of the display pixels of the sense region are coupled to ground while others of the data lines are coupled to the sense line, the sense line being coupled to a touch circuit in order to sense a touch or near touch on the device.
