Abstract: The disclosure provides a pressure detection method of a bonding device and a bonding system. The pressure detection method of a bonding device includes forming a backplane substrate including a light emitting element, disposing a pressure detection sheet on the backplane substrate, transferring the backplane substrate and the pressure detection sheet into a chamber, bonding the light emitting element by pressurizing the pressure detection sheet, photographing the pressure detection sheet, and detecting a color developing area of the pressure detection sheet. In the pressure detection method of the bonding device and the bonding system, it can be inspected whether uniform pressure is applied to a pressure detection sheet.

Abstract: A laser pressure head module including: a pressure member including: a first light-transmitting member; a second light-transmitting member; and a sealed space between the first light-transmitting member and the second light-transmitting member; and a gas supply unit to supply gas to the sealed space to generate a pressing force. The second light-transmitting member is to be expanded or moved in an external direction by the pressing force.

Abstract: A suction unit control method includes simulating an air flow about a suction port, through which fumes generated when a laser beam is radiated on a target substrate on a stage unit to cut the target substrate are sucked up, installing an air blower on three or four sides around a laser cutting end at a height close to the suction port, controlling on and off of first to fourth solenoid valves of the air blower based on a movement of the stage unit while performing laser cutting on the target substrate while moving the stage unit.

Abstract: A cylinder head, a transfer and bonding system and a method of driving the same to produce a display device that includes light emitting elements provides uniform pressure to light emitting elements during a transfer and bonding process. The cylinder head may include a first bracket accommodating the first transmissive portion; a second transmissive portion spaced apart from the first transmissive portion in a direction by an air layer; a second bracket accommodating the second transmissive portion; and an elastic member surrounding side surfaces of the first bracket and the second bracket, wherein one of the first bracket and the second bracket includes an air path that extends to the air layer.
