Signal Processing & Driving: Converts low-voltage digital video signals (e.g., via RGB, LVDS, MIPI DSI interfaces) into the complex timing and voltage waveforms needed to activate individual pixels on the LCD glass. Power Management: Generates and regulates the various specific voltage levels required by the LCD panel (logic power, gate/source driver voltages) and often the backlight (LED driver). Timing Control: Generates critical clock signals (Hsync, Vsync, Dot Clock) to synchronize the row-by-row, pixel-by-pixel updating of the display.
