Abstract:
Devices and methods for reducing display-to-touch crosstalk are provided. In or more examples, an electronic display panel may include a pixel. The pixel may include a pixel electrode, a common electrode, and a first transistor having a first source coupled to a data line, a first gate coupled to a gate line, and a first drain coupled to the pixel electrode. The pixel may also include a second transistor having a second source coupled to the common electrode, a second gate coupled to the gate line, and a second drain coupled to a common voltage source. The second transistor may be configured to cause a parasitic capacitance between the gate line and the second drain of the second transistor and to reduce an effect of a parasitic capacitance between the gate line and the first drain of the first transistor.
