  • Publication number: 20240122041
    Abstract: A display device and a method of manufacturing the same are provided. The display device comprises a substrate comprising a display area in which emission areas are arranged, a main non-display area around the display area, a hole area surrounded by the display area, and an additional non-display area between the hole area and the display area; a circuit layer; a light emitting element layer; a sealing layer; a through portion in the hole area and penetrating at least the substrate; and sealing auxiliary structures in the additional non-display area and sequentially surrounding the hole area. Each of the sealing auxiliary structures comprises a first undercut portion in which a first cover layer protrudes from a first main layer; and a second undercut portion in which a second cover layer protrudes from a second main layer.

  • Patent number: 5162681
    Abstract: There is disclosed a differential sense amplifier for amplifying a small voltage difference between a pair of input signals including: a pair of first complementary drivers for producing signals of different states in response to the pair of input signals and determining the voltage level including one of the pair of input signals; a pair of output terminals connected with the respective outputs of the pair of complementary drivers; and a pair of a second complementary drivers connected between the pair of output terminals to respectively respond to the signals of different states of the first complementary drivers. Each of the first and second complementary drive means includes two insulated gate transistors connected in series and having different operating voltages. A feedback may be provided between the pair of output terminals for fast charging with the power supply voltage and bi-stable output operation.
