DATA DRIVER AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18429200 titled 'DATA DRIVER AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation:
The patent application describes a display device with a display panel containing a sub-pixel, which includes components like capacitors, transistors, and a light-emitting element. A data driver and a timing controller are also included in the device to control the display operation.
- The display panel includes a sub-pixel with a first capacitor, a first transistor for generating a driving current, and a second transistor for providing data or reference voltage to the first capacitor.
- A light-emitting element is present to emit light by receiving the driving current.
- A data driver selectively outputs data voltage or reference voltage to the first capacitor through a source channel.
- The timing controller controls the data driver to ensure proper functioning of the display device.
Key Features and Innovation:
- Integration of capacitors, transistors, and a light-emitting element in a sub-pixel for efficient display operation.
- Use of a data driver and timing controller to manage the display functions effectively.
Potential Applications:
- This technology can be used in various display devices such as smartphones, tablets, and televisions.
- It can also be applied in digital signage, automotive displays, and wearable technology.
Problems Solved:
- Enhances display performance by efficiently controlling the driving current and voltage distribution.
- Improves image quality and overall user experience.
Benefits:
- Higher display resolution and brightness.
- Energy-efficient operation.
- Enhanced visual experience for users.
Commercial Applications:
The technology can be utilized in the consumer electronics industry for manufacturing high-quality display devices with improved performance and energy efficiency.
Questions about Display Devices:
1. How does the integration of capacitors and transistors in a sub-pixel improve display performance? 2. What role does the timing controller play in controlling the data driver for display operation?
Original Abstract Submitted
A display device includes: a display panel including a sub-pixel, the sub-pixel including: a first capacitor; a first transistor to generate a driving current, and including a control electrode connected to the first capacitor; a second transistor connected to the first capacitor, and to provide a data voltage or a reference voltage to the first capacitor in response to a write gate signal; and a light emitting element to receive the driving current to emit light; a data driver to selectively output the data voltage or the reference voltage to the first capacitor through a source channel; and a timing controller to control the data driver.
