Abstract

An adaptive Vcom level generator circuit generates a variable Vcom voltage level. A variable Vcom voltage can be used for variable refresh rate display technology to prevent flicker on a display panel. The Vcom level can be changed based on the vertical frequency being used or can be changed based on external control signals.
