Abstract

The invention discloses a method for welding panel glass of a display. Ultrashort pulse laser is utilized to generate an optical near-field enhancement effect near contact points of the inner surfaces of the panel glass of the display and a glass fiber (or glass bead) spacer (which is positioned between the panel glass of the display), so as to generate multiphoton absorption (ionization) and provide seed electrons, and long pulse laser can be absorbed by the seed electrons; and when melting threshold values of the glass fiber (or glass bead) spacer and the panel glass of the display are reached, two pieces of panel glass of the display are fused and connected together. Along with movement of a laser focus according to a predesigned route, welding and packaging of the panel glass of the integral display are implemented. The method reduces cost of only using the ultrashort pulse laser to weld the glass, improves welding efficiency and implements welding and packaging of the panel glass of the display.

Description

technical field [0001] The invention relates to welding of transparent materials, in particular to a method for welding display panel glass. Background technique [0002] Displays are widely used in many fields. However, the connection (encapsulation) problem of display panel glass has not been well resolved. At present, chemical adhesives are mainly used. Such a connection cannot guarantee good mechanical properties, as well as good thermal and chemical stability. [0003] Recently, a method for welding glass with ultrashort pulse laser has been proposed. The ultrashort pulse laser has a very high peak power, which can realize multi-photon absorption (ionization), that is, the laser beam can pass through the glass surface, and the energy flux density at the laser focus can reach or exceed the multi-photon absorption (ionization) threshold, and the glass will melt , to achieve laser welding. However, ultrashort pulse laser has high cost and low power, and the welding eff...
