Abstract: A scan driver includes a plurality of stages. Each of the plurality of stages includes a control circuit which controls a voltage of a first node and a voltage of a second node in response to an input signal, a first clock signal and a second clock signal, a carry output circuit which outputs a carry signal in response to the voltage of the first node and the voltage of the second node, an enable node controlling circuit which controls a voltage of an enable node in response to the carry signal, an enable signal and an inverted enable signal, a masking circuit which controls a voltage of a third node in response to the voltage of the second node and the voltage of the enable node, and a scan output circuit which outputs a scan signal in response to the voltage of the first node and the voltage of the third node.

Abstract: A pixel includes a first transistor coupled to a first node, a second transistor receiving a writing signal, a third transistor receiving a compensation signal, a first terminal coupled to the third node, and a second terminal coupled to a fourth node, a fourth transistor receiving an initialization signal, a first terminal coupled to the fourth node, and a second terminal coupled to an initialization voltage line, a fifth transistor receiving a first emission signal, a first terminal coupled to the first power supply voltage line, and a second terminal coupled to the second node, a light emitting element coupled to the third node and a second power supply voltage line, and an eighth transistor receiving a second emission signal, a first terminal coupled to the first node, and a second terminal coupled to the fourth node.

Abstract: Disclosed is a circular stapler. The circular stapler includes a head cover (100) formed in a tubular shape so that a space is defined therein, a cartridge (200) provided in one end of the head cover (100) to accommodate a staple therein, a staple drive (300) provided inside the head cover (100) to extrude the staple from the cartridge (200) while moving toward the cartridge (200), a sensor drive (400) provided inside the head cover (100) and configured to come into contact with the cartridge (200), and a pressure sensor (500) provided inside the head cover (200) to measure pressure applied to the cartridge (200) by receiving the pressure from the sensor drive (400).

Abstract: The present disclosure relates to an airbag including a vent hole. The airbag including a vent hole, according to the present disclosure, comprises: a protection means (100) mounted on a predetermined part of a user, and inflated when gas is injected therein, thereby protecting the user; a body part (200) inserted into the vent hole (150), which is formed in the protection means (100), so as to enable fluid to flow through the inner and outer sides of the protection means (100); an elastic body (300) closing the body part (200), and inflated by the pressure of the gas inside the protection means (100) when the gas is injected into the protection means (100); and an opening and closing means (400), which opens the body part (200) by tearing the inflated elastic body (300) after the user falls, so as to discharge, to the outside, the gas injected into the protection means (100).
