DISPLAY APPARATUS AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18454420 titled 'DISPLAY APPARATUS AND METHOD OF MANUFACTURING THE SAME
Simplified Explanation
The abstract describes a display apparatus that includes a substrate with different areas, such as a main display area, a component area, and a peripheral area. The component area has a transmission area, and the peripheral area is located outside the main display area. The display apparatus includes various components such as thin-film transistors and organic light-emitting diodes (OLEDs) arranged in different areas of the substrate.
- The main display area includes a main thin-film transistor and a main OLED connected to it.
- The component area includes an auxiliary thin-film transistor and an auxiliary OLED connected to it.
- A lower metal layer with an undercut structure is placed between the substrate and the auxiliary thin-film transistor in the component area.
Potential applications of this technology:
- Display devices: This display apparatus can be used in various display devices such as televisions, computer monitors, smartphones, and tablets.
- Wearable devices: The compact and efficient design of this display apparatus makes it suitable for integration into wearable devices like smartwatches and augmented reality glasses.
- Automotive displays: The display apparatus can be utilized in the automotive industry for in-car displays, instrument clusters, and heads-up displays.
Problems solved by this technology:
- Efficient use of space: The arrangement of components in different areas of the substrate allows for efficient use of space, maximizing the display area while accommodating necessary components.
- Improved display quality: The use of OLEDs and thin-film transistors in the main and auxiliary areas ensures high-quality and vibrant displays.
- Enhanced manufacturing process: The inclusion of a lower metal layer with an undercut structure helps in the fabrication process, ensuring proper connectivity and functionality of the auxiliary thin-film transistor.
Benefits of this technology:
- Compact design: The display apparatus allows for a compact and slim design, making it suitable for various applications where space is limited.
- High-quality display: The use of OLEDs and thin-film transistors ensures excellent display quality with vibrant colors and high contrast ratios.
- Efficient manufacturing: The inclusion of the lower metal layer with an undercut structure simplifies the manufacturing process, improving production efficiency and yield.
