* Question
| What are the characteristics of the OLED driver? |
* Answer
| (1) OLED is a low-voltage driving device with a driving voltage of 0V to 30V.(2) The OLED pixel can be equivalent to a light-emitting diode and a capacitor in parallel. The capacitance value is related to the pixel area, and the range is 20pF to 30pF.
(3) OLED is an active light-emitting device, and the luminance of the light is proportional to the injection current, so the 0LED is driven by a constant current source. |
