240-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 64-GRAY SCALES)

NEC => Renesas Technology 

µPD161830

·MODE = H (GND output driving)

When a MODE pin is set as H, the output change function by AP pin is changed as follows.

AP Pin

H

Sn Pin (source output) Drive

GND output (VSS fixed)

Normal AMP operation

As for sauce output, output is fixed to ground (VSS) in falling of AP signal at the time of GND output drive (MODE =

H). Moreover, the return to an APM drive usually returns from the next STB = H period which latched AP = H by the

rising edge of STB signal. The relationship of the CLK signal at the time of a GND output drive, a STB signal, AP

signal, and Sn state is shown as follows.
