双色球连号走势图 1.VDD, VDDIO, VCC what is the voltage?
VDD is the OLED screen logic drive voltage, different driver IC, the voltage range is not the same, such as SSD1305, its range is 2.4-3.5V.
VDDIO is the IO port of the logic voltage, generally with the data line of the high voltage level.
双色球连号走势图 VCC is the OLED module screen drive voltage, different screen body, the voltage value is not the same. (Some specifications also write VPP to VCC)
双色球连号走势图 2. Power and life and brightness have anything to do?
The size of the power consumption and the number of pixels lit up directly related to the LCD with a backlight compared to its much smaller power consumption, the same product, life and brightness are directly related, inversely.
双色球连号走势图 3. What are the advantages of OLED?
Compared with LCD, OLED with active light, no backlight, no viewing angle, light weight, thin thickness, high contrast, fast response, wide temperature range, soft display, seismic ability, simple process and a series of advantage.
4. Why OLED wide temperature?
双色球连号走势图 OLED light-emitting materials are solid, in different ambient temperature, the physical characteristics of stability. The liquid crystal is between the liquid and solid material between the high temperature will become liquid, and too low will become a solid state, the physical form will change, seriously affect the display.
双色球连号走势图 5. OLED driver interface and LCD What is the difference?
双色球连号走势图 OLED drive interface more widely, not only support 8080,6800 parallel port, also supports SPI, I2C and other commonly used LCD interface, the circuit connection is very convenient.
6. OLED software with the LCD than what is the difference?
OLED software processes and LCD the same basic, Ai Shun good technical staff will provide customers with the relevant initialization code to help customers quickly embedded development.
双色球连号走势图 7. OLED structure design process need to pay attention to?
双色球连号走势图 Because the screen body substrate is glass, and relatively thin, so the need for structural positioning in the design process, with the PCB card position or structure of the card position fixed display, and increase the corresponding anti-shock foam to enhance the product's seismic performance.
8.OLED in the drive boost circuit design process need to pay attention to what the problem?
General requirements boost IC load capacity is greater than the maximum power consumption of the screen body can be recommended after the completion of the external circuit design by Ai Shun good technical staff to confirm.
9. OLED display how to adjust the brightness?
双色球连号走势图 Adjust the hardware drive voltage and software code values can be adjusted OLED display brightness, please consult the specific Ai Shun good technical staff.
