True black and high-fidelity colors in TFT-LCD systems require state-of-the-art system solutions. A 12.3-inch backlight panel that houses a full-array of 256 LEDs implements local dimming for true-black using only four chips. A gamma buffer IC delivers 16 voltage references with 10-bit resolution, providing the least amount of gamma variation from panel to panel. A complete TFT bias chip provides the panel with all the necessary rails. Finally, a slew of standby, low-noise, and POL voltage regulators provide the necessary high-voltage and low-voltage rails for a complete TFT-LCD display system solution.
