DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18442816 titled 'DISPLAY DEVICE
The patent application describes a display device with light-emitting elements, pixel circuits, drive transistors, and coupling switching transistors to control the emission of light from the elements.
- The display device includes a plurality of light-emitting elements arranged in a display region.
- Each light-emitting element is connected to a first pixel circuit and a second pixel circuit.
- A first drive transistor supplies a first drive current to the light-emitting element through the first pixel circuit.
- A second drive transistor supplies a second drive current to the light-emitting element through the second pixel circuit.
- A drive circuit provides a video signal to both the first and second drive transistors.
- A first coupling switching transistor is placed between the first drive transistor and the light-emitting element.
- A second coupling switching transistor is placed between the second drive transistor and the light-emitting element.
- The coupling switching transistors are turned off during non-emission periods of the light-emitting element.
Potential Applications: - This technology can be used in various types of display devices, such as televisions, monitors, and digital signage. - It can also be applied in wearable technology, augmented reality devices, and automotive displays.
Problems Solved: - The technology helps improve the efficiency and performance of display devices by controlling the emission of light more effectively. - It enhances the overall image quality and reduces power consumption.
Benefits: - Enhanced image quality and brightness. - Improved energy efficiency and longer battery life for portable devices. - Better control over the light emission process, leading to more accurate display of colors and images.
Commercial Applications: - The technology can be utilized by display manufacturers to create high-quality and energy-efficient products for consumer electronics, automotive, and industrial applications.
Questions about the technology: 1. How does the use of coupling switching transistors improve the performance of the display device? 2. What are the potential cost implications of implementing this technology in mass-produced devices?
