Note:
*1. This rating applies to all parts of the module. And should not be exceeded.
*2. The operating temperature only guarantees operation of the circuit. The contrast, response speed,
and the other specification related to electro-optical display quality is determined at the room temperature, T OP =25 ℃
*3. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional
operation of this device at other conditions beyond those listed in the specification is not implied and prolonged
exposure to extreme conditions may affect device reliability.
