7. ການປະຕິບັດການພິຈາລະນາ
To ensure optimal performance and longevity of your OLED module, please observe the following:
- ການເຊື່ອມຕໍ່ພະລັງງານ: Be careful not to reverse the power connection (VCC and GND) as this can damage the module.
- Self-Luminous Display: OLED displays are self-luminous and do not have a backlight. Simply connecting VCC and GND will not illuminate the display. You must use program control to highlight the OLED and display content.
- ການຮັກສາຮູບພາບ: Avoid displaying the same static screen content for prolonged periods. Continuous display of static images can lead to residual images (burn-in) and potentially damage the OLED panel.
8. ການແກ້ໄຂບັນຫາ & FAQ
- Q: How many volts can the OLED module be used in a system?
- A: The OLED module is designed for use in a 3.3V system by default. However, extensive testing has shown that it functions reliably in a 5V system as well.
- Q: How many hours does the OLED module last?
- A: Under normal operating conditions, the OLED module typically has a lifespan of approximately 50,000 hours.
- Q: OLED module connected to the power supply why does not light?
- A: OLED displays are self-luminous and do not have a backlight. The display will not light up by simply connecting VCC and GND. You must use program control to initialize the display and send data to illuminate the OLED and show content.
