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.
