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.
  • Helps in achieving consistent color reproduction and brightness levels.
  • Improves overall image quality and viewing experience.

Benefits of this technology:

  • Enhanced visual quality with accurate color representation.
  • Improved energy efficiency by optimizing gamma voltage generation.
  • Enables better calibration and adjustment of display parameters.
  • Provides a more immersive and enjoyable viewing experience.


Original Abstract Submitted

A driving device of a display panel includes a reference voltage generator, a capacitor circuit, and a gamma voltage generator. The reference voltage generator is configured to generate a maximum gamma voltage and a minimum gamma voltage. The capacitor circuit is configured to, response to receiving the first driving voltage, charge a first charge based on a voltage difference between a first driving voltage and the maximum gamma voltage and charge a second charge based on a voltage difference between the first driving voltage and the minimum gamma voltage. The capacitor circuit is configured to, in response to receiving a second driving voltage, output a first gamma reference voltage and a second gamma reference voltage. The gamma voltage generator is configured to generate a plurality of gamma voltages based on the first gamma reference voltage and the second gamma reference voltage.
