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.
