1. A physical article of manufacture including one or more non-transitory computer-readable storage media, storing computer-executable instructions for executing on a computer system a computer process, the computer process comprising:
measuring a liquid crystal (LC) common voltage (VCOM) over a predetermined period of operation of an LCD panel having a plurality of LCs;
determining a shift in the VCOM (VCOM shift) over the predetermined period based at least in part on the measured VCOM;
storing the VCOM shift as a function of time in a table of an embedded controller;
receiving a power-on signal for the LCD panel after the storing; and
adjusting, responsive to the receiving, a VCOM reference level applied to the LCs based at least in part on the stored values of the VCOM shift to maintain the VCOM of the LCD panel at a level relative to a voltage level during a positive frame and a voltage level during a negative frame.
