Abstract
Methods and devices for improving image quality in a display having multiple common voltage layers (VCOMs) are provided. In one example, a method may include maintaining a deactivation signal on pixels of the display after programming a frame of data onto the pixels of the display, but before a touch sequence. The method may also include supplying a first data signal to each pixel of a first set of pixels coupled to a first VCOM while maintaining the deactivation signal. The method may include supplying a second data signal to each pixel of a second set of pixels coupled to a second VCOM while supplying the first data signal. The first data signal is supplied to each pixel of the first set of pixels and the second data signal is supplied to each pixel of the second set of pixels to inhibit image distortion during the touch sequence.
