Display Apparatus and Electronic Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18253108 titled 'Display Apparatus and Electronic Device
Simplified Explanation
The abstract describes a display panel that includes a substrate, a photoelectric detector, and a display surface. The photoelectric detector is located on the substrate side close to the display surface and includes a PN junction or a PIN junction. The detector is biased in a specific way during an ambient light detection stage to generate a photo-generated current and detect ambient light information. The detector is positioned above the substrate, allowing ambient light to penetrate only a part of the display panel's film layer structure to be received.
- The display panel includes a photoelectric detector that detects ambient light information.
- The photoelectric detector is located on the substrate side close to the display surface.
- The detector includes a PN junction or a PIN junction.
- The detector is biased in a specific way during an ambient light detection stage.
- The detector generates a photo-generated current under illumination of ambient light.
- The detector is positioned above the substrate, allowing ambient light to penetrate only a part of the display panel's film layer structure to be received.
Potential Applications
This technology can be applied in various display devices, such as:
- Smartphones and tablets, where the display panel can adjust brightness based on ambient light conditions.
- Televisions and monitors, where the display can optimize image quality based on ambient light levels.
- Automotive displays, where the panel can adapt to different lighting conditions for better visibility.
Problems Solved
The technology addresses the following problems:
- Inaccurate ambient light detection in display devices, leading to suboptimal brightness or image quality.
- Limited ability to adapt to changing lighting conditions, resulting in discomfort or reduced visibility.
- Inefficient use of energy by not adjusting display brightness based on ambient light levels.
Benefits
The benefits of this technology include:
- Improved accuracy in detecting ambient light, allowing for better adjustment of display brightness and image quality.
- Enhanced user experience by automatically adapting the display to different lighting conditions.
- Energy efficiency by optimizing display brightness based on ambient light levels, reducing power consumption.
Original Abstract Submitted
A display panel includes a substrate, a photoelectric detector, and a display surface. The photoelectric detector is located on a side that is of the substrate and that is close to the display surface. The photoelectric detector includes a PN junction or a PIN junction. The photoelectric detector is configured to be reverse biased or zero biased when the display apparatus works in an ambient light detection stage to generate a photo-generated current under illumination of ambient light and detect ambient light information. The photoelectric detector is disposed above the substrate, and ambient light needs to penetrate only a part of a film layer structure of the display panel to be received by the photoelectric detector.
