Abstract
A voltage reference circuit and method for producing a voltage as a reference voltage for a liquid crystal display (LCD) panel. The voltage reference circuit with controllable temperature coefficients includes a logic operation unit and a voltage selection circuit. The logic operation unit receives a command corresponding to the temperature coefficient of an LCD panel and provides a selection signal according to the command. The selection signal is applied to the voltage selection circuit. Depending on the selection signal, the voltage selection circuit generates a selected voltage which is used to produce a reference voltage.
