Clamped‐inverter circuit architecture for luminescent‐period‐control driving of active‐matrix OLED displays

— An innovative pixel-driving technology for high-performance active-matrix OLED flat-panel displays is described. Called “clamped-inverter circuit architecture,” it uses luminescent-period-control driving to reduce the inter-pixel non-uniformity caused by the device-to-device variability of low-temperature poly-Si TFTs. A prototype full-color display shows a luminous deviation of less than 1.6%, which corresponds to only the LSB-error in 6-bit gray-scale.
