The invention discloses a method for carrying out vacuum encapsulation binding on reinforcing glass of a liquid crystal display module. The method comprises the following steps that foam double-face adhesive tapes are pasted on the periphery outside an effective display zone of a liquid crystal box in a covering mode, and the foam double-face adhesive tapes define a foam rectangle which is provided with an air outlet and an adhesive tape inlet on the diagonal lines respectively; the reinforcing glass is placed on the foam double-face adhesive tapes and is fixed in a pasting mode through the foam double-face adhesive tapes, and then sealants are arranged on the zone, except the air outlet and the adhesive tape inlet, on the outer edge between the reinforcing glass and the liquid crystal box in a coating mode; a vacuum generator and a dispenser are connected to the air outlet and the adhesive tape inlet respectively, and vacuum encapsulation of optical cement is carried out; and then the optical cement is solidified to form an optical cement layer, and the whole vacuum encapsulation binding process is completed. The method has the advantages that the thickness, the bubble number, excessive cement and the like of the optical cement layer can be well controlled, the finished product pass percent is improved, displaying quality is improved, and cost is lowered.
