TAILOR PIXELS TECHNOLOGY CO., LTD. 1.5 Power Supply for Logic This is a voltage supply pin. It must be connected to external source. Ground of Logic Circuit This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground. Power Supply Power Supply for OEL Panel This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used. Voltage Output High Level for COM Signal This pin is the input pin...

TAILOR PIXELS TECHNOLOGY CO., LTD. 2. Absolute Maximum Ratings Parameter Supply Voltage for Logic Supply Voltage for Display Supply Voltage for DC/DC （Internal DC/DC Enable） 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...

TAILOR PIXELS TECHNOLOGY CO., LTD. 4. Functional Specification 4.1 Commands Refer to the Technical Manual for the SSD1315 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. 2. 3. 4. 5. 6.
