Semiconductor. It contains two voltage-feedbacks (1.20V and 0.90V) to adapt to a wide range of LCD contrast settings. Its GPM feature allows for reduction of power consumption and precise dimming control. To conform to various power standards, the IC is equipped with an integrated DC/DC converter, and ±5V and PWM outputs for backlight drive. It also supports various protections including VCOM Over-voltage Protection, ESD protection, and will reduce power consumption especially in scenes with bright displays.
