Preliminary
■ Output timing (HD66787)
HD66787 outputs timing signals (FLM, CL1, SFTCLK) for controlling low-temperature poli-Si TFT
(LTPS-TFT) panels with incorporated gates. The output timing of CL1 can be adjusted by instructions for
controlling LTPS-TFT interface. Set an optimum timing for the configuration of gate circuits incorporated
in the LTPS-TFT panel in use.
