Abstract

Generally, displays, like liquid crystal displays (LCDs), use a DC-free addressing voltage in order to prevent decomposition of the display. Here, an integrated circuit (IC) is provided that compensates for temperature dependencies. This IC typically uses a thermistor or temperature varying element to measure the temperature of the display and adjusts the common reference voltage in response to the measured temperature.
