In this paper, we present a fast TFT threshold voltage extraction method adapting iterative feedback. Using this method we can obtain relative TFT threshold voltage Vth of all pixels in the AMOLED display. According the relative TFT threshold voltage, we can compensate the driving data to significantly improve the uniformity of AMOLED display.

Equivalent lifetime method to estimate the luminance degradation degree and improve the lifetime of the OLEDs was proposed. The equivalent lifetime was calculated by converting the display time at different luminance with the same degradation degree with ascertained luminance decay curve. The calculation accuracy can reach 99.98% and lifetime can extend 13.3%.

This paper proposes an implementation framework based on local contrast enhancement (LCE). The framework, implemented on Xilinx Kintex‐7 FPGA platform, is lighted on the 55″ Ultra‐High Definition (UHD) LCD panel and shows the result of image contrast enhancement. In accordance with the hardware design concept, the implementation framework adopts the module partition, hardware parallel processing structure and pipeline processing architecture. The hardware implementation fully achieves the real‐time requirements.
