Description
12-Bit Data Input for Even Channels. VID(0, 2, 4, 6, 8, 10), MSB = DBA11.
12-Bit Data Input for Odd Channels. VID(1, 3, 5, 7, 9, 11), MSB = DBB11.
Simultaneously initiates a new data loading sequence and transfers data
loaded previously, to the outputs.
Digital Power Supplies.
These pins are normally connected to the digital ground plane.
Clock Input.
Selects Single Buss or Dual Buss Operating Modes.
Selects Left Direction or Right Direction Operating Mode.
Enables and Disables Column Inversion.
Changes the Polarity of the Analog Output Signals.
Enables and Disables Grounded Mode.
Enables and Disables Long-Term Output Protection.
Analog Supply Returns.
Analog Power Supplies.
A 0.1 μF capacitor connected between BYP and AGND ensures optimum
settling time.
Connect This Pin to AGND.
No Connect. No internal connection.
These pins are connected directly to the analog inputs of the LCD panel.
This Voltage Sets the Video Center Voltage. The video outputs are above
this reference while INV = HIGH and below this reference while INV = LOW.
Twice the voltage applied between VRH and VRL sets the full-scale
video output voltage.
