DISPLAY DEVICE WITH CONSISTENT LUMINANCE AT DIFFERENT REFRESH RATES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240127751 titled 'DISPLAY DEVICE WITH CONSISTENT LUMINANCE AT DIFFERENT REFRESH RATES
Simplified Explanation
The subject matter described in this disclosure includes a pixel circuit with an LED and a driving transistor connected to supply power to the LED. The pixel circuit also includes two additional transistors connected between the LED and an initialization voltage line, with one transistor connected to a scan line and the other connected to a reset line. The pixel circuit is designed so that activating the scan line at a certain frequency and the reset line at half that frequency causes the LED to be initialized every other time the scan line is activated.
- LED pixel circuit with driving transistor and two additional transistors
- Transistors connected to scan line and reset line for LED initialization
