Abstract

The invention provides an adjusting structure for reducing bubbles in a fritting sealing process. A laser beam adjusting lens and a semi-transparent semi-reflective lens are sequentially arranged between a laser head and a fritting material along a principal optic axis of the laser head. The fritting process is completed by irradiating the fritting material with a laser spot. The adjusting structure for reducing the bubbles in the fritting sealing process provided by an embodiment of the invention utilizes the semi-transparent performance of a light transmitting film to improve energy distribution of the laser beam, so that the energy uniformity of the laser beam is improved. Furthermore, combination of the lens and the light transmitting film enables the energy distribution and the spot shape to be well matched, so that requirements for the fritting dimension of the Frit packaging technology can be flexibly met.

Description

technical field [0001] The invention relates to a sintered structure, in particular to a sintered structure of glass powder. Background technique [0002] The Frit (fusion bonding) packaging process of AM-OLED is to avoid the penetration of moisture and oxygen to the greatest extent. The fritted glass powder is used between the transparent anode and the metal reflective cathode on the edge of the panel. The laser heats the fritted glass powder through the transparent anode to fuse the glass powder to form a moisture and oxygen barrier. [0003] However, due to laser uniformity, the energy distribution of the laser beam is normally distributed from the center to the edge. In order to ensure that the average energy intensity of the beam can meet the fusion energy threshold, the energy intensity at the center of the beam is often much higher than the fusion energy threshold, so that the H in the LTPS film layer on the side of the frit glass frit + Released, gasified during th...
