Reducing touch pixel coupling

摘要

A touch screen to reduce touch pixel coupling. In some examples, the touch screen can include a first display pixel and a second display pixel in a row of display pixels, where the first display pixel can be configurable to be decoupled from the second display pixel during at least a touch sensing phase of the touch screen. In some examples, the touch screen can include a display pixel having a first and a second transistor, where the second transistor can be electrically connected to a gate terminal of the first transistor, and can be diode-connected. In some examples, the touch screen can include two display pixels, each display pixel having two transistors, where two of the transistors can be electrically connected to a first gate line, and the remaining two transistors can be individually electrically connected to a second and third gate line, respectively.

主权项

1. A touch screen comprising:
a first drive region; a first sense region; and a first display pixel in the first drive region coupled to a first gate line, wherein the first display pixel includes a first transistor, and wherein the first transistor includes a first gate; and a second display pixel in the first sense region coupled to a second gate line, different from the first gate line, wherein the second display pixel includes a second transistor, and wherein the second transistor includes a second gate; wherein the first gate line is coupled to the first gate and the second gate line is coupled to the second gate, wherein the first gate line is decoupled from the second gate line during at least a touch sensing phase of the touch screen, and wherein the first gate line is coupled to the second gate line at least during a display phase of the touch screen.
