**Chip Select**
This pin is the chip select input. The chip is enabled for MCU communication
only when CSB is pulled low.
**Power Reset for Controller and Driver**
This pin is reset signal input. When the pin is low, initialization of the chip is
executed.
**Data/Command Control**
This pin is Data/Command control pin. When the pin is pulled high, the input at
D7~D0 will be interpreted 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 SI
will be interpreted as data. When it is pulled low, the data at SI 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.
**Serial Data Input/Output and clock**
When serial mode is selected, D1 will be the serial data input SI and D0 will be the
serial clock input SCL.
When I2C mode is selected, D1 be the serial data input SDA and D0 is the serial
clock input, SCL.|

- Note 1: All the above voltages are on the basis of “GND B = 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: End of lifetime is specified as 50% of initial brightness reached. The reference average operation life time at room temperature is estimated by the accelerated at high temperature conditions.

## **`4. Functional Specification`**
## 4.1 Commands
Refer to the Technical Manual for the SH1107
## 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.
## 4.2.1 Power up Sequence:
1. Power up VB `DD`
- B B
- 2. Send Display off command
3. Initialization
4. Clear Screen
5. Power up VB `PP` B
6. Delay 100ms
- (When VB `PP` is stable)
7. Send Display on command
- 4.2.2 Power down Sequence:
1. Send Display off command
2. Power down VB `PP` B
3. Delay 100ms (When VB `PP` is reach 0 and panel is completely discharges)
4. Power down VB `DD` B

**----- End of picture text -----**
Note 9:
- 1) Since an ESD protection circuit is connected between VB `DD` B and VB `PP` B inside the driver IC, VB `PP` B becomes lower than V B `DD` B whenever VB `DD` B is ON and VB `PP` B is OFF.
- 2) V `PP` B should be kept float (disable) when it is OFF.
- 3) Power Pins (VB `DD` B, V `PP` ) can never be pulled to ground under any circumstance.
- 4) VB `DD` B should not be power down before V `PP` power down.
## 4.3 Reset Circuit
When RESB input is low, the chip is initialized with the following status:
1. Display is OFF. Common and Segment are in high impedance state.
2. 128 × 128 Display Mode
3. Normal segment and display data column and row address mapping (SEG0 is mapped to the top line of the display).
4. Shift register data clear in serial interface
5. Column address counter is set at 0
6. Normal scan direction of the COM outputs
7. Contrast control register is set at 80h
8. Internal DC-DC is selected
