TODAY’S PATENT – DISPLAY DEVICE
The said invention (US11721269B2) was invented by Yang Wan Kim, Su Jin Lee, Sun Ja Kwon, Byung Sun Kim, Hyun Ae Park, Hyung Jun Park, Jae Yong Lee, and Yu Jin JEON on 22nd September 2016. Currently; it stands assigned to Samsung Display Co Ltd.
This display device features a substrate with different pixel areas and a surrounding peripheral area. It uses a dummy part in the peripheral area to balance load differences between pixel lines, ensuring uniform brightness. The dummy part overlaps the lines, providing parasitic capacitance, and includes an insulating layer with contact holes connecting an active pattern to a metal layer linked to the power supply.
The device also includes layers like passivation, pixel-defining, and sealing layers for durability. Scan and emission control lines are connected to the pixels and overlap with the dummy part to enhance performance and stability, maintaining consistent display quality.
