DISPLAY APPARATUS INCLUDING A THIN-FILM TRANSISTOR INCLUDING A SILICON SEMICONDUCTOR AND A THIN-FILM TRANSISTOR INCLUDING AN OXIDE SEMICONDUCTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18095076 titled 'DISPLAY APPARATUS INCLUDING A THIN-FILM TRANSISTOR INCLUDING A SILICON SEMICONDUCTOR AND A THIN-FILM TRANSISTOR INCLUDING AN OXIDE SEMICONDUCTOR

Simplified Explanation

The patent application describes a display apparatus that includes a display area and a non-display area. The display area has a display element and the non-display area has a pad portion.

  • The display apparatus includes a first thin-film transistor (TFT) made of silicon and a first gate electrode arranged in the display area.
  • A second TFT made of an oxide and a second gate electrode is arranged on a first insulating layer covering the first gate electrode.
  • A first voltage line extends in a first direction and a data line is spaced apart from the first voltage line.
  • A connection wire is present in the display area and connects the data line to the pad portion.
  • The connection wire has a first portion that extends in the first direction and a second portion that extends in a second direction crossing the first direction. The first portion overlaps the first voltage line.

Potential applications of this technology:

  • Display devices such as televisions, computer monitors, and mobile phone screens.
  • Electronic signage and billboards.
  • Virtual reality and augmented reality headsets.

Problems solved by this technology:

  • Improved connectivity between the data line and the pad portion.
  • Enhanced performance and reliability of the display apparatus.
  • Reduction in manufacturing complexity and cost.

Benefits of this technology:

  • Higher quality display with improved connectivity.
  • Increased durability and reliability of the display apparatus.
  • Simplified manufacturing process leading to cost savings.


Original Abstract Submitted

A display apparatus is provided including a display area and a non-display area. The display area includes a display element and the non-display area includes a pad portion. A first thin-film transistor (TFT) is arranged in the display area. The first TFT includes silicon and a first gate electrode. A second TFT is arranged on a first insulating layer covering the first gate electrode and includes an oxide and a second gate electrode. A first voltage line extends in a first direction. A data line is spaced apart from the first voltage line. A connection wire is disposed in the display area and connects the data line to the pad portion. The connection wire includes a first portion extending in the first direction and a second portion extending in a second direction crossing the first direction, and the first portion overlaps the first voltage line.
