DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18750067 titled 'DISPLAY DEVICE
The display device described in the patent application consists of several layers, including a base layer, a circuit element layer, a light emitting element layer, a thin film sealing layer, and an input sensing layer.
- The base layer has an active area and a peripheral area, with the circuit element layer containing a pixel circuit in the active area and driving voltage wiring in the peripheral area.
- The light emitting element layer houses multiple light emitting elements on top of the circuit element layer, with the thin film sealing layer covering them.
- The input sensing layer, located on the thin film sealing layer, includes a sensing electrode and a sensing signal wiring part connected to it.
- The circuit element layer features a connection wiring part that overlaps the driving voltage wiring in the peripheral area and contacts the sensing signal wiring part, with the connection wiring part being at a different layer from the driving voltage wiring.
Potential Applications: - This technology could be used in the development of high-resolution displays for electronic devices. - It may find applications in the creation of touch-sensitive screens with enhanced functionality.
Problems Solved: - The technology addresses the need for efficient driving voltage supply to pixel circuits in display devices. - It enables seamless integration of input sensing capabilities into display screens.
Benefits: - Improved display performance and resolution. - Enhanced user interaction through touch-sensitive features.
Commercial Applications: Title: Advanced Display Technology for Enhanced User Experience This technology could be utilized in the production of smartphones, tablets, and other electronic devices with interactive display screens, catering to the growing demand for high-quality visuals and user-friendly interfaces.
Questions about the technology: 1. How does the input sensing layer enhance the functionality of the display device? 2. What are the advantages of having the connection wiring part at a different layer from the driving voltage wiring?
Original Abstract Submitted
A display device includes a base layer including an active area and a peripheral area outside the active area, a circuit element layer including a pixel circuit in the active area and a driving voltage wiring located in the peripheral area to supply a driving voltage to the pixel circuit. A light emitting element layer including a plurality of light emitting elements on the circuit element layer, a thin film sealing layer to cover the light emitting element layer, and an input sensing layer on the thin film sealing layer and including a sensing electrode and a sensing signal wiring part connected to the sensing electrode. The circuit element layer includes a connection wiring part overlapping the driving voltage wiring in the peripheral area and contacts the sensing signal wiring part. The connection wiring part is at a different layer from the driving voltage wiring.
