PIXEL AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17971445 titled 'PIXEL AND DISPLAY DEVICE INCLUDING THE SAME

Simplified Explanation

The abstract describes a pixel structure for a display device, which includes various transistors and capacitors to control the emission of light from the pixel.

  • The pixel includes a light-emitting element and several transistors.
  • The first transistor has two gate electrodes and is connected to the light-emitting element.
  • The second transistor is connected between a data line and the second gate electrode of the first transistor.
  • The third transistor is connected between two nodes and is turned on by a second scan signal.
  • The fourth transistor is connected between the first node and a power line and is turned on by a first scan signal.
  • The fifth transistor is connected between the first power line and the first transistor and is turned off by a first emission control signal.
  • The sixth transistor is turned off by a second emission control signal.
  • A first capacitor is connected between the first power line and the first node.

Potential Applications:

  • This pixel structure can be used in various display devices such as televisions, computer monitors, and mobile devices.
  • It can be applied in both OLED (organic light-emitting diode) and LCD (liquid crystal display) technologies.

Problems Solved:

  • The pixel structure provides precise control over the emission of light from the pixel, resulting in improved image quality and energy efficiency.
  • It solves the problem of unwanted light emission and leakage in display devices.

Benefits:

  • The pixel structure allows for efficient control of light emission, resulting in better contrast and color accuracy in display devices.
  • It helps in reducing power consumption and extending the battery life of devices.
  • The structure enables high-resolution displays with improved image quality.


Original Abstract Submitted

A pixel may include a light-emitting element, a first transistor including first and second gate electrodes, a second transistor which is connected between a data line and the second gate electrode, and turned on in response to a third scan signal, a third transistor which is connected between first and second nodes, and turned on in response to a second scan signal, a fourth transistor which is connected between the first node and a third power line, and turned on in response to a first scan signal, a fifth transistor which is connected between the first power line and the first transistor, and turned off in response to a first emission control signal, a sixth transistor which is turned off in response to a second emission control signal, and a first capacitor connected between the first power line and the first node.
