ELECTROLUMINESCENT DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18231576 titled 'ELECTROLUMINESCENT DISPLAY DEVICE AND METHOD OF DRIVING THE SAME

Simplified Explanation

The abstract describes an electroluminescent display device with a pixel driving circuit.

  • The device includes a light emitting element and a circuit to drive the element.
  • The pixel driving circuit consists of several transistors and a storage capacitor.
  • The transistors are connected to different nodes and lines to control the driving current.
  • The first transistor is connected to three nodes, while the second and third transistors are connected between nodes.
  • The fourth transistor is connected to a driving voltage line and the first node.
  • The fifth transistor is connected between the second node and a fourth node.
  • The seventh transistor is connected between the fourth node and a reset voltage line.
  • The storage capacitor is placed between the first driving voltage line and the third node.


Original Abstract Submitted

An electroluminescent display device can include a light emitting element; and a pixel driving circuit for applying a driving current to the light emitting element, in which the pixel driving circuit includes a first transistor connected to the first, second and third nodes; a second transistor connected between the third node and the second node; a third transistor connected between the first node and a data line; a fourth transistor connected between the first node and a first driving voltage line; a fifth transistor connected between the second node and a fourth node; a seventh transistor connected between the fourth node and a reset voltage line, and a storage capacitor disposed between the first driving voltage line and the third node.
