Pin Definition

Pin1,  C2P /  Pin2, C2N /  Pin3, C1P /  Pin4, C1N   

Positive Terminal of the Flying Inverting Capacitor, Negative Terminal of the Flying Boost Capacitor. The charge-pump capacitors are required between the terminals. They must be floated when the converter is not used.

Pin5,  VDD2 VBAT        

Power Supply for DC/DC Converter Circuit. This is the power supply pin for the internal buffer of the DC/DC voltage converter.It must be connected to external source when the converter is used. It should beconnected to VDD when the converter is not used.

Pin6,  VBREF     NC

Pin7,  VSS          

Ground of Logic CircuitThis is a ground pin. It acts as a reference for the logic pins. It must beconnected to external ground.

Pin8,  VDD1          

Power Supply for Logic. This is a voltage supply pin. It must be connected to external source.

Pin9,   RES#       

Power Reset for Controller and Driver. This pin is reset signal input. When the pin is low, initialization of the chip isexecuted. Keep this pin pull high during normal operation.

Pin10, SCL       

 IIC Bus Clock Signal. The transmission if information in the I2C bus is following a clock sigmal. Eachtransmission of data bit is taken place during a single clock period of this pin.

Pin11, SDA         

I2C Bus Data Signal. This pin acts as a communication channel between the transmitter and the receiver.

Pin12, IREF        

Current Reference for Brightness Adjustment. This pin is segment current reference pin. A resistor should be connectedbetween this pin and VSS. Set the current at 12.5uA maximum.

Pin13, VCOMH   

Voltage Output High Level for COM Signal. This pin is the input pin for the voltage output high level for COM signals. Acapacitor should be connected between this pin and VSS.

Pin14, VCC         

Power Supply for OEL Panel. This is the most positive voltage supply pin of the chip. A stabilization capacitorshould be connected between this pin and VSS when the converter is used. Itmust be connected to external source when the converter is not used.

Note 1: All the above voltages are on the basis of “VSS = 0V”.

Note 2: When this module is used beyond the above absolute maximum ratings, permanent breakage of themodule may oPPur. Also, for normal operations, it is desirable to use this module under theconditions aPPording to Section 3. “Optics & Electrical Characteristics”. If this module is usedbeyond these conditions, malfunctioning of the module can oPPur and the reliability of the modulemay deteriorate.

Note 3: The defined temperature ranges do not include the polarizer. The maximum withstoodtemperature of the polarizer should be 80°C.

Note 4: VPP = 7.5V, Ta = 25°C, 50% Checkerboard.Software configuration follows Section 4.4 Initialization.End of lifetime is specified as 50% of initial brightness reached. The average operating lifetime atroom temperature is estimated by the aPPelerated operation at high temperature conditions.

* Optical measurement taken at VDD1 = 2.8V, VPP = 8.0V & 7.4V.Software configuration follows Section 4.4 Initialization.
