Parade Technologies Sampling Power-Saving Tcon-Embedded Driver (TED) for TFT Panels

Parade Technologies, a San Jose, California, supplier of high-speed interface, video display, and touch controller ICs, announced a new offering in its eDP Timing Controller with Embedded Driver (TED) product category. The TC3230 features support for higher resolutions as well as the most advanced Embedded DisplayPort features for power savings.

TC3230 is compliant with the eDP 1.5 standard and supports Multi-SST Operation (MSO), Panel Self-Refresh, DSC 1.2a, ALPM, and more. The TC3220 is configurable to support all panel resolutions up to 2560×1600 using an 18 or 24-bit color format. Adding a second TC3230, in MSO+DSC mode, enables panel resolutions up to 3840×2160. With support for the standard based embedded video interface protocols offered by major CPU, GPU and SoC vendors, system implementation is straight-forward. The integrated source drivers support up to 2562 output channels with support for dual-gate and MUX2/MUX3 sub-pixel driving structures.

The TC3230 is designed for Chip on Glass (COG) application on LTPS (Low Temperature Polycrystalline Silicon), a-Si (Amorphous Silicon) or Oxide type TFT panels. It requires no external crystal or timing reference, includes a programmable gamma buffer, as well as Parade’s exclusive Smart-Backlight™ feature for additional color and power optimization. The fully programmable row and column driver timing enables the TC3230 to serve a broad range of panels types, and it provides synchronization signals that support a wide range of touch controllers.

“At the same time that the displays on our mobile and portable devices push to higher and higher resolutions, the search for extended battery life only intensifies. By offering the TC3230 we address both of these market desires with one product,” said Jimmy Chiu, Executive VP of Marketing at Parade Technologies. “By offering both the TC3230 and the recently announced TC3222, we are delivering targeted solutions, with highly integrated TED solution for both high-end and main-stream slim TFT panels, whether in a-Si, Oxide, or LTPS, and at resolutions from 1080P to 4K and beyond.”

For solutions that are less power-sensitive, and don’t require the support of PSR (Panel Self Refresh) the TC3222 offers many of the same features as the TC3230 but targets the value segment.


The TC3230 is offered in a gold-bumped COG (Chip-on-Glass) physical form factor. Samples are available now.
