Publication number: 20240065057Abstract: A display may include pixels arranged in rows and columns in an active area and display driver circuitry in an inactive area. Data lines for the pixels may be positioned in the active area. Fanout lines may be routed through the active area. Each fanout line may electrically connect the display driver circuitry to a respective data line. One or more pixels may include a drive transistor and a light-emitting diode that are connected in series between a first power supply terminal and a second power supply terminal. A conductive layer may form a first terminal (such as the source terminal, the gate terminal, or the drain terminal) for the drive transistor. A conductive shielding layer may be interposed between the conductive layer and a fanout line to mitigate capacitive coupling between the terminal of the drive transistor and the fanout line.Type: ApplicationFiled: June 2, 2023Publication date: February 22, 2024Inventors: Shin-Hung Yeh, Abbas Jamshidi Roudbari, Chien-Ya Lee, I-Cheng Shih, Shyuan Yang, Tsung-Ting Tsai

Patent number: 8013334Abstract: The present invention provides a bonding structure of circuit substrates for instant circuit inspecting. The connecting wire design of the bonding structure has an instant inspection ability of circuit connection in bonding two circuit substrates. In two bonded circuit substrates, the signal inputted at the circuit part passes the conductive particles to the first connecting wire, and then passes the conductive particles again to the detecting part from the first connecting wire. Therefore, measuring the output signal can inspect the reliability of the circuit connection of the bonded circuit substrates. If the output signal is the same as the input signal, the bonding structure between the first connecting wire and the circuit part is validated, or, if not, the bonding structure is invalidated.Type: GrantFiled: May 7, 2010Date of Patent: September 6, 2011Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Ming-Tan Hsu, I-Cheng Shih
