DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18072507 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes several transistors and a light emitting element. Here is a simplified explanation of the abstract:
- The display device has a first transistor that controls a control current based on the voltage of a first node.
- A second transistor connects a second node (first electrode of the first transistor) to a first data line when a scan write signal is received.
- A third transistor controls a driving current based on the voltage of a third node.
- A fourth transistor connects a fourth node (first electrode of the third transistor) to a second data line when the scan write signal is received.
- A fifth transistor controls the driving current based on the voltage of a fifth node, which has received the control current.
- A light emitting element receives the driving current.
- The fifth transistor is of a different type from the first to fourth transistors.
Potential applications of this technology:
- Display devices: This technology can be used in various types of display devices, such as televisions, computer monitors, smartphones, and wearable displays.
- Electronic signage: The display device can be used for creating electronic signs and billboards.
- Virtual reality and augmented reality: This technology can be utilized in VR/AR headsets and devices to provide high-quality displays.
Problems solved by this technology:
- Efficient control of current: The use of multiple transistors allows for precise control of the driving current, resulting in improved efficiency and performance of the display device.
- Enhanced image quality: The technology helps in achieving better image quality by accurately controlling the current flowing through the light emitting element.
- Compatibility with different transistor types: The inclusion of a fifth transistor of a different type allows for flexibility in the design and integration of the display device.
Benefits of this technology:
- Improved energy efficiency: The precise control of current helps in reducing power consumption, leading to improved energy efficiency of the display device.
- High-quality display: The technology enables better image quality with vibrant colors, high contrast, and accurate brightness levels.
- Design flexibility: The inclusion of a different type of transistor provides flexibility in the design and integration of the display device, allowing for customization and optimization based on specific requirements.
