7. RELATIONSHIP BETWEEN MODE, STB, SRC, ORC, POL, AND OUTPUT WAVEFORM

When MODE = H or open and STB = H, all outputs are reset (short) and the gray-scale voltage is output to LCD in

synchronization with the falling edge of STB.

When MODE = L and STB = H, all outputs became Hi-Z and the gray-scale voltage is output to the LCD in

synchronization with the falling edge of STB.

Also, setting the SRC pin to H level allows the bias current value of the output amplifier to rise temporarily, and

setting the ORC pin to H level allows the output resistance value of the amplifier to lower temporarily.

For the timing and the processing of STB, SRC, or ORC during a high-level period, We recommend a thorough

evaluation of the LCD panel specifications in advance.
