7. RELATIONSHIP BETWEEN STB CLK AND OUTPUT WAVEFORM
loaded with the rising edge of the next CLK[1′]. Latch operation of display data is completed with the falling edge of the
next CLK which loaded STB = H. Therefore, in order to complete latch operation of display data, it is necessary to input
at least 2 CLK in STB = H period. Besides, after loading STB=H to the timing of [1], it is necessary to continue inputting
CLK.
