DEP 20203-Y Production Specification 10. Precautions in use of OLED Modules (1) Avoid applying excessive shocks to module or making any alterations or modifications to it. (2) Don’t make extra holes on the printed circuit board, modify its shape or change the components of OLED display module. (3) Don’t disassemble the OLED display module. (4) Don’t operate it above the absolute maximum rating. (5) Don’t drop, bend or twist OLED display module. (6) Soldering: only to the I/O terminals.
DEP 20203-Y Production Specification (7) Do not apply stress to the LSI chips and the surrounding molded sections. (8) Do not disassemble nor modify the OLED display module. (9) Do not apply input signals while the logic power is off. (10) Pay sufficient attention to the working environments when handing OLED display modules to prevent occurrence of element breakage accidents by static electricity. * Be sure to make human body grounding when handling OLED display modules.
DEP 20203-Y Production Specification 11.3 Designing Precautions (1) The absolute maximum ratings are the ratings which cannot be exceeded for OLED display module, and if these values are exceeded, panel damage may be happen. (2) To prevent occurrence of malfunctioning by noise, pay attention to satisfy the VIL and VIH specifications and, at the same time, to make the signal line cable as short as possible. (3) We recommend you to install excess current preventive unit (fuses, etc.
