Interface
Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low, initialization of the chip is
executed. Keep this pin pull high during normal operation.
Chip Select
This pin is the chip select input. The chip is enabled for MCU communication only
when CS# is pulled low.
Data/Command Control
This pin is Data/Command control pin. When the pin is pulled high, the input at
D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0
will be transferred to the command register.
When the pin is pulled high and serial interface mode is selected, the data at SDIN
will be interpreted as data. When it is pulled low, the data at SDIN will be
transferred to the command register. In I2C mode, this pin acts as SA0 for slave
address selection.
For detail relationship to MCU interface signals, please refer to the Timing
Characteristics Diagrams.

This pins acts as a communication channel. The input data through SDIN are latch
at the rising edge of SCLK in fhe sequence of MSB first and converted to 8-bit
parallel data and handled at the rising edge of last serial clock.

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 the
module may occur. Also, for normal operations, it is desirable to use this module under the
conditions according to Section 3. “Optics & Electrical Characteristics”. If this module is used
beyond these conditions, malfunctioning of the module can occur and the reliability of the module
may deteriorate.
Note 3: The defined temperature ranges do not include the polarizer.
The maximum withstood
temperature of the polarizer should be 80°C.
Note 4: VCC = 9.0V, 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 at
room temperature is estimated by the accelerated operation at high temperature conditions.

4. Functional Specification
4.1 Commands
Refer to the Technical Manual for the CH1116
4.2 Power down and Power up Sequence
To protect OEL panel and extend the panel life time, the driver IC power up/down routine should include
a delay period between high voltage and low voltage power sources during turn on/off. It gives the
OEL panel enough time to complete the action of charge and discharge before/after the operation.

Note 13:
1) Since an ESD protection circuit is connected between VDD and VCC inside the driver IC, VCC
becomes lower than VDD whenever VDD is ON and VCC is OFF.
2) VCC / VBAT should be kept float (disable) when it is OFF.
3) Power Pins (VDD, VCC, VBAT) can never be pulled to ground under any circumstance.
4) VDD should not be power down before VCC / VBAT power down.
4.3 Reset Circuit
When RES# input is low, the chip is initialized with the following status:
1. Display is OFF
2. 128×64 Display Mode
3. Normal segment and display data column and row address mapping (SEG0 mapped to column
address 00h and COM0 mapped to row address 00h)
4. Shift register data clear in serial interface
5. Display start line is set at display RAM address 0
6. Column address counter is set at 0
7. Normal scan direction of the COM outputs
8. Contrast control register is set at 7Fh
9. Normal display mode (Equivalent to A4h command)
