DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310952 titled 'DISPLAY DEVICE
The patent application describes a display device that includes unit pixels, each consisting of display pixels, a light sensing pixel, and touch electrodes for sensing touch.
- The unit pixels are arranged in a way that display pixels and a light sensing pixel are surrounded by touch electrodes in different regions.
- A main driving circuit analyzes the light sensing signal from the light sensing pixel to detect fingerprints.
- The touch electrodes have open areas between the light sensing pixel and display pixels in each unit pixel.
Potential Applications: - Biometric security systems - Interactive displays - Touchscreen devices
Problems Solved: - Enhanced security through fingerprint detection - Improved touch sensitivity and accuracy
Benefits: - Increased security features - Enhanced user experience with precise touch detection
Commercial Applications: Title: Advanced Biometric Security Display Technology This technology can be used in smartphones, tablets, laptops, and other devices requiring secure authentication methods. It can also be applied in public kiosks, ATMs, and access control systems.
Questions about the Technology: 1. How does the main driving circuit analyze the light sensing signal to detect fingerprints?
The main driving circuit analyzes variations in the light sensing signal to identify unique fingerprint patterns.
2. What are the potential challenges in implementing this technology in mass-produced devices?
Ensuring consistent performance across different devices and environments may pose challenges in mass production.
Original Abstract Submitted
a display device includes unit pixels, each unit pixel including display pixels and a light sensing pixel, touch electrodes sensing a touch and, when viewed in a plan view, surrounding a first region where each of at least two display pixels is disposed and a second region where the light sensing pixel and one of the display pixels that is different from the at least two display pixels are disposed, and a main driving circuit receiving a light sensing signal from the light sensing pixel and sensing a fingerprint by analyzing the light sensing signal. the touch electrodes define at least one open area in which no touch electrode is formed between the light sensing pixel and at least one display pixel in each unit pixel.
