Embodiment Construction

[0059] The laser packaging device and packaging method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the invention will be apparent from the claims and the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0060] refer to figure 1 , this embodiment provides a laser packaging device, which can be formed on a packaging substrate such as Figure 4 , Figure 5 As shown in the appearance of the spot, the light intensity from the edge of the spot to the center of the spot on the surface perpendicular to the direction of the laser beam travels gradually decreases. Figure 4 , the light intensity distribution of the spot can be divided into the first section B a...

Abstract

The present invention provides a laser packaging device and a packaging method. The laser packaging device irradiates a laser beam onto a packaging substrate to form a spot. On the surface perpendicular to the direction of the laser beam traveling route, the spot edge reaches the The light intensity at the center of the light spot decreases gradually, the light spot includes a first section close to the edge of the light spot and a second section close to the center of the light spot, and the light intensity decrease ratio of the first section is smaller than the first section The light intensity reduction ratio of the two sections, the boundary position between the first section and the second section is the first inflection point. The encapsulation of the encapsulation substrate by using the laser beam of the light spot provided by the present invention can effectively improve the uniformity of the dose irradiated on the glass frit, and further improve the sealing performance of the frit.

Description

technical field [0001] The invention relates to the field of optoelectronic semiconductors, in particular to a laser packaging device and a packaging method. Background technique [0002] Optoelectronic semiconductor devices have been widely used in various fields of life. Among them, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has become a research hot spot due to its good color ratio, wide viewing angle, high response speed and other characteristics, and has a good application prospect. However, electrodes and organic layers in OLED devices are very sensitive to oxygen and moisture. Oxygen and moisture permeating into OLED devices from the external environment will seriously shorten the lifetime of OLED devices. Therefore, it is very important to provide an effective hermetic seal for OLED devices. The hermetic sealing of OLED devices has the following requirements: [0003] The hermetic seal shall provide protection against oxygen (10 -3 cm 3 / ...
