DIGITAL ANALOG MULTIPLICATION DRIVING METHOD FOR A DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18164266 titled 'DIGITAL ANALOG MULTIPLICATION DRIVING METHOD FOR A DISPLAY DEVICE
Simplified Explanation
The present disclosure describes methods and apparatuses for operating a display device, specifically a micro-LED display. The method involves driving each pixel in the display, where the pixels are arranged in an array of rows and columns.
- Each frame is divided into Nd time sections.
- In each time section, one of Ba different voltage levels is applied to the pixel.
- Ba is equal to or greater than 3.
- The brightness, grey scale color, or luminance of the pixel is determined by the sum of the results of multiplying the length of each time section by the applied voltage level.
Potential applications of this technology:
- Micro-LED displays in various electronic devices such as smartphones, tablets, and televisions.
- High-resolution displays for virtual reality (VR) and augmented reality (AR) applications.
- Automotive displays for dashboards and infotainment systems.
Problems solved by this technology:
- Provides a method for driving each pixel in a display device, ensuring accurate control of brightness, grey scale color, or luminance.
- Enables the use of micro-LED technology in displays, which offers advantages such as high brightness, low power consumption, and fast response time.
Benefits of this technology:
- Improved image quality with precise control of brightness and color.
- Energy-efficient displays with low power consumption.
- Faster response time for smooth and seamless visuals.
Original Abstract Submitted
The present disclosure provides operating methods and apparatuses of a display device. In an implementation, a method includes driving each pixel for each frame, wherein a plurality of pixels of the display device are disposed in an array of rows and columns, where a period of one frame comprises Nd time sections, one of Ba different voltage levels is applied to the pixel in each time section, Ba is greater than or equal to 3, the sum of the results of multiplying the length of each time section by the applied voltage level corresponds to a brightness, grey scale color, or luminance. One of suitable applications of the present invention is a micro-LED display.
