Title: MULTI-ZONED VARIABLE VCOM CONTROL
Abstract:
The disclosure relates to systems and methods for reducing VCOM settling periods. A number of pixels is sub-divided into a plurality of regions. The pixels are configured to transmit light. A common voltage (VCOM) driving circuit is configured to drive a common electrode of the pixels. Moreover, each of a number of VCOM driving circuits includes a variable resistor configured to be driven to a resistance level based at least in part on which region of the plurality of regions includes an active pixel within the region. Furthermore, a resistance level is set and based at least in part on where the active pixel is located.
