Abstract
The present invention provides a method for sealing a peripheral frame of a display screen. The method for sealing a peripheral frame of a display screen includes providing a display screen that comprises a first substrate and a second substrate and the first substrate comprises a panel zone covered by the second substrate and a peripheral frame located outside the panel zone and making the display screen suction-attached to a substrate suction-holding platform to have one side of the second substrate that is distant from the first substrate attached to a separation and protection film provided on the substrate suction-holding platform with an edge of the first substrate set at predetermined spacing from a positioning plate provided on the substrate suction-holding platform so that a sealant injection device is operable to inject sealant along and into a gap between the edge of the first substrate and the positioning plate to achieve coating uniformity of sealant on the peripheral frame and precise control of thickness of sealant, and only a low level of accuracy of the sealant injection device is required to thereby greatly reduce manufacturing costs.
