TAILOR PIXELS TECHNOLOGY CO., LTD. 1.5 Power Supplly for OEL Panell This is the most positive voltage supply pin of the chip. It must be supplied externally. Power Supplly for Logiic This is a voltage supply pin. It must be connected to external source. Ground of OEL System This is a ground pin. It also acts as a reference for the logic pins, the OEL driving voltages, and the analog circuits. It must be connected to external ground. Power Supply Driver Current Reference for Brightness Adjustment This pin is segment current reference pin. A resistor should be connected between this pin and VSS....

TAILOR PIXELS TECHNOLOGY CO., LTD. 2. Absolute Maximum Ratings Parameter Supply Voltage for Logic Supply Voltage for Display Operating Temperature Storage Temperature 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...

TAILOR PIXELS TECHNOLOGY CO., LTD. 4. Functional Specification 4.1 Commands Refer to the Technical Manual for the SSD1312 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 VDD 2. Send Display off command 3. Initialization 4. Clear Screen 5. Power up VPP 6. Delay 100ms (When...
