DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18221944 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device with multiple pixels, each consisting of a driving thin film transistor and a storage capacitor. Each pixel includes several components:

  • A driving semiconductor layer with a driving channel region, driving source region, and driving drain region.
  • A first electrode layer that partially overlaps the driving channel region.
  • A second electrode layer that overlaps the first electrode layer.
  • A node connection line connected to the first electrode layer.
  • A pixel electrode that overlaps the first electrode layer and the second electrode layer.
  • A shielding layer between the first electrode layer and the pixel electrode, overlapping the first electrode layer, node connection line, and pixel electrode.

Bullet points explaining the patent/innovation:

  • The display device includes a driving thin film transistor and storage capacitor in each pixel, allowing for individual control and storage of pixel information.
  • The driving semiconductor layer provides the necessary components for the transistor's operation, including the channel, source, and drain regions.
  • The first electrode layer partially overlaps the driving channel region, enabling efficient control of the transistor's conductivity.
  • The second electrode layer overlaps the first electrode layer, contributing to the overall functionality of the pixel.
  • The node connection line connects to the first electrode layer, facilitating the transmission of electrical signals.
  • The pixel electrode overlaps the first and second electrode layers, serving as the main contact point for the pixel's electrical signals.
  • The shielding layer between the first electrode layer and pixel electrode helps prevent interference and ensures accurate signal transmission.
  • This display device design offers improved performance and reliability, making it suitable for various applications requiring high-quality visual output.


Original Abstract Submitted
