DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18139848 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with a substrate that includes a display area and a non-display area with a pad area adjacent to one side of the display area. The device also includes a light emitting element, a pad portion with output pads, a driving chip, and a control signal line.
- The driving chip has a base portion facing the substrate, dummy bump areas, an output bump area, and a data output area.
- Dummy bumps are attached to the base portion and overlap the dummy bump areas and the output bump area.
- Output bumps are attached to the base portion, overlap the output bump area, and are connected in parallel through transistors.
- Detection bumps are attached to the base portion, electrically connected to the output bumps, and overlap the output bump area.
- The control signal line is connected through the transistors to the output bumps.
Potential applications of this technology:
- Display devices in electronic devices such as smartphones, tablets, and laptops.
- LED screens for advertising displays and digital signage.
Problems solved by this technology:
- Efficient and reliable connection between the driving chip and the output pads.
- Improved performance and functionality of display devices.
Benefits of this technology:
- Enhanced display quality and brightness.
- Increased durability and longevity of display devices.
- Simplified manufacturing process for display devices.
Original Abstract Submitted
A display device includes: a substrate including a display area and a non-display area positioned around the display area and including a pad area adjacent to one side of the display area, a light emitting element disposed in the display area on the substrate, a pad portion disposed in the pad area on the substrate and including a plurality of output pads, a driving chip, and a control signal line. The driving chip includes a base portion facing the substrate, overlapping the pad area, and including dummy bump areas, an output bump area positioned between the dummy bump areas, and a data output area positioned between the dummy bump areas, a plurality of dummy bumps attached to a lower surface of the base portion and overlapping the dummy bump areas and the output bump area, respectively, a plurality of output bumps attached to the lower surface of the base portion, overlapping the output bump area, and connected in parallel to each other through transistors, and a plurality of detection bumps attached to the lower surface of the base portion, each of the detection bumps is electrically connected to the output bumps and overlapping the output bump area. The control signal line electrically connected through the transistors to the output bumps.
