DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18094924 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes various layers and components to improve light sensing and display capabilities. Here are the key points:
- The display device includes a light sensing array layer (LSAL), a substrate, a selective light transmission layer (SLTL), a pixel circuit layer (PCL), a display element layer (DEL), and pixels.
- The LSAL has an optical sensor to sense incident light.
- The substrate is placed on top of the LSAL and consists of a display area (DA) with pixel areas (PAs) and a non-DA area adjacent to it.
- The SLTL is located on the substrate and has through-holes that create a path for light to reach the optical sensor. It also includes a light-blocking conductive pattern (LBCP) between the through-holes.
- The PCL is positioned on the SLTL and consists of a conductive layer and an insulation layer.
- The DEL is placed on the PCL and emits light.
- Each pixel includes a pixel circuit on the PCL and a light emitting element on the DEL in a corresponding pixel area.
- The LBCP is electrically connected to the conductive layer.
Potential applications of this technology:
- High-resolution displays: The display device can be used in high-resolution screens for smartphones, tablets, televisions, and other electronic devices.
- Augmented reality (AR) and virtual reality (VR): The improved light sensing capabilities can enhance AR and VR experiences by accurately detecting and responding to ambient light conditions.
- Automotive displays: The display device can be integrated into vehicle dashboards, infotainment systems, and heads-up displays to provide clear and vibrant visuals.
Problems solved by this technology:
- Improved light sensing: The LSAL and SLTL layers enhance the device's ability to sense and measure incident light accurately, allowing for better display performance under different lighting conditions.
- Light-blocking: The LBCP helps prevent unwanted light from reaching the optical sensor, reducing interference and improving the accuracy of light measurements.
Benefits of this technology:
- Enhanced display quality: The combination of improved light sensing and pixel circuitry allows for more precise control over the emitted light, resulting in sharper images and better color reproduction.
- Energy efficiency: The device's ability to accurately measure ambient light can optimize the display's brightness and power consumption, leading to energy savings.
- Versatility: The display device can be integrated into various electronic devices and applications, providing flexibility and adaptability to different user needs.
Original Abstract Submitted
A display device including a light sensing array layer (LSAL), a substrate, a selective light transmission layer (SLTL), a pixel circuit layer (PCL), a display element layer (DEL), and pixels. The LSAL includes an optical sensor to sense incident light. The substrate is on the LSAL and includes a display area (DA) including pixel areas (PAs), and a non-DA adjacent to the DA. The SLTL is disposed on the substrate and includes through-holes to form a path of light onto the optical sensor, and a light-blocking conductive pattern (LBCP) between the through-holes. The PCL is disposed on the SLTL and includes a conductive layer and an insulation layer. The DEL is disposed on the PCL and emits light. Each pixel includes a pixel circuit disposed on the PCL, and a light emitting element on the DEL in a corresponding pixel area. The LBCP is electrically connected to the conductive layer
