DISPLAY DEVICE, METHOD OF MANUFACTURING THE SAME AND TILED DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17856464 titled 'DISPLAY DEVICE, METHOD OF MANUFACTURING THE SAME AND TILED DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The patent application describes a display device that includes a first substrate, fan-out lines, a second substrate, connection lines, a thin film transistor, a third metal layer, and a flexible film. The device has specific etching angles for the contact holes.
- The display device includes a first substrate with a contact hole, fan-out lines, a second substrate with a contact hole, connection lines, a thin film transistor, a third metal layer, and a flexible film.
- The etching angle of the first contact hole is smaller than the etching angle of the second contact hole.
- The fan-out lines are connected to the flexible film through the first contact hole.
- The connection lines are connected to the fan-out lines through the second contact hole.
- The thin film transistor is located in an active layer and the third metal layer is on top of the second metal layer.
Potential applications of this technology:
- Display devices in electronic devices such as smartphones, tablets, and televisions.
- Flexible displays that can be bent or curved.
- High-resolution displays with improved connectivity.
Problems solved by this technology:
- Ensures proper connection between the fan-out lines and the flexible film.
- Provides a reliable and efficient display device.
- Reduces the risk of damage or disconnection of the connection lines.
Benefits of this technology:
- Improved display quality and resolution.
- Enhanced flexibility and durability of the display device.
- Simplified manufacturing process for display devices.
Original Abstract Submitted
A display device includes a first substrate including a first contact hole, fan-out lines in a first metal layer, a second substrate on the first metal layer and including a second contact hole, connection lines in a second metal layer and into the second contact hole connected to the fan-out lines, a thin film transistor in an active layer and a third metal layer on the second metal layer, and a flexible film on a surface of the first substrate and into the first contact hole connected to the fan-out lines. An etching angle of the first contact hole between a top surface of the first substrate and an inner surface of the first contact hole is less than an etching angle of the second contact hole between top surfaces of the fan-out lines and an inner surface of the second contact hole.
