Assumed an LCD with a certain resolution, a defined LCD drive mode (commonly called multiplex rate) and a defined LCD bias configuration (commonly called bias system), the display contrast depends on the VLCD voltage, also called operating voltage of the display.
This document describes the NXP UM10782, an LCD driver featuring an integrated charge pump and regulator designed to generate the VLCD (operating) voltage. The primary function of this component is to optimize display contrast by precisely setting the VLCD voltage based on the specific characteristics of the connected LCD panel.
| Operating temperature range (Industrial) | -40 °C to 85 °C |
|---|---|
| Operating temperature range (Automotive) | -40 °C to 95 °C or 105 °C |
| Document identifier | UM10782 |
The device supports an operating temperature range from -40 °C to 85 °C.
Automotive qualified versions support temperatures up to 105 °C.
Optimization is achieved by programming a register through an interface.
