The TC3220 is a highly integrated eDP Timing Controller (Tcon) embedded driver (TED) IC developed for thin-profile LCD display panels.  It supports all panel resolutions up to 1920×1200 using an 18 or 24-bit color format.  The Tcon input is eDP 1.4b compliant but does not support the optional PSR (Panel Self-Refresh) or PSR2 featurs; for PSR and PSR2 support, please refer to the TC3210.  TC3220 provides a single-chip display driver solution that replaces the traditional multi-chip solution consisting of an eDP Tcon mated up with separate source driver chips.  The TC3220 is designed for Chip-on-Glass (COG) panel assembly to support the new generation of sleek LCD panel modules.

The TC3220 is designed for Flip Chip on Glass application on both LTPS (Low-Temperature Polycrystalline Silicon) and Oxide TFT (thin-film transistor) panels. Mounting the highly integrated TC3220 directly onto the LCD panel results in reduced display form factor, BOM cost, and power consumption, all of which benefit portable, battery-powered systems.  The TC3220 requires no external crystal or timing reference, includes a programmable gamma buffer, and includes Parade’s exclusive Smart-Backlight™ feature for additional color and power optimization.  Fully programmable row and column driver timing enables the TC3220 to serve a broad range of panels types.
