Application note
Using the STVM100 to fully auto adjust LCD flicker
Introduction
Liquid crystal displays (LCDs), from advanced VGA computer monitors to wide-screen TVs,
are very popular with consumers. Compared to its conventional cathode-ray tube (CRT)
counterpart, the LCD screen is superior as it is lightweight, thin, and consumes less power.
Another advantage is that in principle the LCD screen does not flicker as much as a CRT
screen and the flicker on an LCD screen can be minimized. This application note presents
the principle of LCDs and the cause of flicker. We also propose a solution of automatically
minimizing flicker using the STVM100 (LCD VCOM calibrator).
