1. What are the voltages of VDD, VDDIO and VCC?

  VDD is the logic drive voltage of OLED screen, different driver IC, the voltage range is different, such as SSD1305, its range is 2.4-3.5V.

  VDDIO is the logic voltage of the IO port, which is usually equal to the voltage of the high level of the data line.

  VCC is the driving voltage of the screen of the OLED module, and the voltage value is different for different screen bodies. (Some specifications also write VCC as VPP)

2. What is the relationship between power consumption and lifetime and brightness?

  Power consumption is directly related to the number of pixel dots, compared with LCD with backlight, its power consumption is much smaller, the same product, life expectancy and brightness have a direct relationship, inversely proportional.

3. What are the advantages of OLED?

  Compared with LCD, OLED has active light, no backlight, no perspective problems, light weight, thin thickness, high contrast, fast response, wide range of use temperature, can achieve a soft display, shock resistance, simple process and a series of advantages.

4.OLED why wide temperature?

  OLED light-emitting material is solid, in different ambient temperatures, the physical properties of stable. Liquid crystal is between liquid and solid material, in the temperature is too high will become liquid, and too low will become solid, the physical form will change, seriously affect the display.

5. What is the difference between the drive interface of OLED and LCD?

  OLED's driver interface is more extensive, not only supports 8080, 6800 parallel port, but also supports SPI, I2C and other interfaces commonly used in LCD, which is very convenient in circuit connection.

6. What is the difference between the software of OLED and LCD?

  The software process of OLED is basically the same as LCD, and Aisunjia technical staff will provide customers with the relevant initialization code to assist customers in rapid embedding development.

7.What do I need to pay attention to in the process of OLED structure design?

  Because the screen substrate is glass and thin, it needs structural positioning in the design process, fixing the display with PCB clamping or structural clamping, and increasing the corresponding anti-vibration foam to strengthen the product's anti-vibration performance.

8.OLED in the process of driving the booster circuit design needs to pay attention to what issues?

  The general requirement is that the load capacity of the boost IC is greater than the maximum power consumption of the screen, and it is recommended that the peripheral circuit design be confirmed by Aisunjia technical personnel after completion.

9.How to adjust the brightness of OLED display?

  Adjusting the hardware drive voltage and software code value can adjust the OLED display brightness, please consult SINDA technical personnel for details.
