The invention discloses a method for improving poor bubbles in a full-lamination blind hole of a touch display screen of a blind hole type mobile phone. The technical scheme is that the method comprises the following steps: S1, cleaning; s2, two-point positioning is carried out; s3, assembling a CG + OCA component; s4, performing vacuum pumping; s5, defoaming is carried out; the CG + OCA assembly is made of protective glass and a touch screen in an attached mode, and the method for improving the bad bubbles of the full-attached blind holes of the touch display screen of the blind hole type mobile phone has the beneficial effects that after a pre-assembly process is changed from overall contact positioning of the CG + OCA assembly and an LCD attaching face to two-point position contact positioning, the positions of the blind holes are in a hollowed-out and unclosed state; the air in the blind holes can be effectively discharged after vacuum-pumping lamination to form blind hole vacuum bubbles, the blind hole v
