BACKLIGHT UNIT, DISPLAY DEVICE COMPRISING SAME, AND METHOD FOR MANUFACTURING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18247789 titled 'BACKLIGHT UNIT, DISPLAY DEVICE COMPRISING SAME, AND METHOD FOR MANUFACTURING DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with multiple metal wiring layers and insulating layers.
- The device includes a substrate, first metal wiring layers, and a first insulating layer covering the wiring.
- A second metal wiring layer is stacked on top of the first insulating layer, with a gap between them.
- The second metal wiring layer consists of a first metal layer with lower conductivity and a second metal layer with higher conductivity.
- The first metal layer acts as a barrier to prevent diffusion of the second metal layer.
Potential applications of this technology:
- Display devices such as LCD screens, OLED displays, or touchscreens.
- Electronic devices like smartphones, tablets, laptops, or televisions.
- Automotive displays, wearable devices, or gaming consoles.
Problems solved by this technology:
- Prevents diffusion of high-conductivity metal layers into insulating layers, ensuring proper functioning of the display device.
- Reduces the risk of short circuits or electrical interference between different metal layers.
- Enhances the overall performance and reliability of the display device.
Benefits of this technology:
- Improved durability and longevity of display devices.
- Enhanced electrical conductivity and signal transmission within the device.
- Enables the production of more efficient and high-quality displays.
Original Abstract Submitted
A display device according to embodiments of the present invention comprises: a substrate; a plurality of first metal wiring layers formed on the substrate; a first insulating layer stacked on the substrate to cover the first metal wiring; a second metal wiring layer stacked on at least a portion of the first insulating layer so as to be spaced apart therefrom; and a second insulating layer stacked on the second metal wiring. The second metal wiring layer comprises: at least one first metal layer having a first conductivity; and at least one second metal layer having a higher conductivity than the first metal layer, wherein the first metal layer may block diffusion of the second metal layer.
