DISPLAY PANEL DRIVING DEVICE AND DISPLAY PANEL DRIVING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18061588 titled 'DISPLAY PANEL DRIVING DEVICE AND DISPLAY PANEL DRIVING METHOD
Simplified Explanation
The driving device of a display panel described in the patent application includes a reference voltage generator, a capacitor circuit, and a gamma voltage generator. The reference voltage generator generates a maximum and minimum gamma voltage. The capacitor circuit charges based on the voltage difference between the driving voltage and the maximum/minimum gamma voltage. In response to a second driving voltage, the capacitor circuit outputs a first and second gamma reference voltage. The gamma voltage generator generates multiple gamma voltages based on the gamma reference voltages.
- The reference voltage generator generates maximum and minimum gamma voltages.
- The capacitor circuit charges based on the voltage difference between the driving voltage and the gamma voltages.
- The capacitor circuit outputs gamma reference voltages in response to a second driving voltage.
- The gamma voltage generator generates multiple gamma voltages based on the gamma reference voltages.
Potential applications of this technology:
- Display panels in electronic devices such as smartphones, tablets, and televisions.
- LCD screens in computer monitors and laptops.
- OLED screens in wearable devices like smartwatches.
Problems solved by this technology:
- Ensures accurate and precise gamma voltage generation for optimal display performance.
