Claim 19:
20. The method according to claim 19, wherein the touch insulating layer comprises a first insulating layer and a second insulating layer; and
forming the touch layer on the side of the encapsulation layer distal from the light-emitting device comprises:
forming a first insulating material film layer on the side of the light-emitting device distal from the drive back plate;
forming the first touch electrode layer on the drive back plate formed with the first insulating material film layer;
forming a second insulating material film layer on the drive back plate formed with the first touch electrode layer;
performing a patterning process on the second insulating material film layer and the first insulating material film layer, to form the first insulating layer from the second insulating material film layer, and form the second insulating layer from the first insulating material film layer; and
forming the second touch electrode layer on the first insulating layer.
