DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17944313 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with multiple display areas and subpixels.
- The display device includes a substrate with three display areas: a first display area, a second display area with a light-transmitting part, and a third display area between the first and second display areas.
- Each subpixel consists of a thin-film transistor (TFT) and a light-emitting element.
- The first subpixel has a TFT and a light-emitting element on the first display area.
- The second subpixel has a TFT on the third display area and a light-emitting element on the second display area, which does not overlap with the TFT.
- A thin-film encapsulation layer covers both subpixels.
- A transparent conductive layer is placed between the second TFT and the second light-emitting element to establish an electrical connection.
- The thin-film encapsulation layer has a refractive index between 1.5 and 1.7.
Potential applications of this technology:
- Display devices with improved image quality and clarity.
- Flexible or curved displays with multiple display areas.
- Displays with enhanced light transmission and reduced reflection.
Problems solved by this technology:
- Overlapping of TFTs and light-emitting elements in a display device can cause interference and reduce image quality. This design eliminates the overlap, improving display performance.
- The thin-film encapsulation layer with a specific refractive index helps reduce reflection and enhance light transmission, resulting in better image quality.
Benefits of this technology:
- Improved image quality and clarity in display devices.
- Enhanced light transmission and reduced reflection for better visibility.
- Potential for flexible or curved displays with multiple display areas.
Original Abstract Submitted
A display device includes: a substrate including a first display area, a second display area including a light-transmitting part, and a third display area between the first and second display areas; a first subpixel including a first TFT on the first display area and a first light-emitting element on and electrically connected to the first TFT; a second subpixel including a second TFT on the third display area and a second light-emitting element, which is on the second display area and does not overlap with the second TFT in a plan view; a thin-film encapsulation layer on the first and second subpixels,; and a first transparent conductive layer between the second TFT and the second light-emitting element to electrically connect the second TFT and the second light-emitting element. The thin-film encapsulation layer has a refractive index of about 1.5 to about 1.7.
