Display timing that tunes itself to every panel
A self-tuning display timing controller. Instead of fixed correction tables, a small on-chip NPU calibrates to the specific panel at every power-on, it generates a test pattern, measures the error, and adjusts its own correction parameters, with no CPU, no firmware and no factory calibration station. It also retrains over the panel lifetime to counter aging.

RISC-V Architecture
A small RISC-V core runs control and lifetime retraining while a tightly-coupled NPU performs per-pixel correction at pixel rate, and the self-tuning loop calibrates the panel at every boot. The RISC-V core replaces the traditional microcontroller with no license fee.
Key Features
Self-calibration at every boot
The chip calibrates itself to the specific panel on every power-on, no external station needed.
No firmware or factory tuning
No CPU firmware to maintain and no factory calibration line, the silicon tunes itself.
Lifetime retraining
It retrains over the panel lifetime to counter aging and keep the picture accurate.
Tiny NPU footprint
A compact on-chip NPU delivers per-pixel correction without a large area cost.
SDR, HDR and low-power banks
Dedicated parameter banks switch the panel between SDR, HDR and low-power modes.
RISC-V replaces the microcontroller
Our own RISC-V core handles control and retraining, removing the licensed microcontroller.
