Embodiment Construction

[0035] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0036] The embodiment of the present invention provides a mask, please refer to image 3 The reticle includes a light-shielding area 101 , an opening area 102 and a light-shielding plate 103 , and the light-shielding plate 103 can be arranged in different predetermined sections on the opening area 102 and cover the predetermined sections.

[0037] In this embodiment, the opening area 102 is ring-shaped, and the opening area 102 is a light-transmitting area.

[0038] The light-shielding area 101 includes a first light-shielding pattern surrounded by the opening area 102 and a second light-shielding pattern surrounding the opening area 102 .

[0039] The shading plate 103 can be made of the same material as that of the shading area 101 . The shading plat...

Abstract

The invention provides a mask and a display device packaging method using the mask. The mask comprises a shading area, an opening area and a shading plate; the shading plate can be arranged into different preset section area on the opening area and used for shading the preset section area. According to the mask and the display device packaging method using the mask, when irradiating the sealant with a laser head, the laser head is controlled to be within the preset section area on the opening area, covered with the shading plate during being accelerated or decelerated, thus the laser head can be kept in a constant-speed moving state to the maximum during irradiating the sealant, the same laser energy can be irradiated to the silicon sealant in each area, the problem of different solidifying degree of the sealant can be solved, and as a result, the effect of packaging a display device can be improved.

Description

technical field [0001] The invention relates to the field of packaging technology, in particular to a mask plate and a display device packaging method using the mask plate. Background technique [0002] In the process of preparing organic light emitting diode (OLED) devices, encapsulation is a very important process step, and the quality of encapsulation directly affects the service life of OLED devices. Because the organic materials used in the preparation of OLED devices are all materials that are very sensitive to water and oxygen, once they come into contact with water and oxygen, they will lose their original characteristics, thus making the OLED device invalid. [0003] At present, in small and medium-sized OLED devices, the best encapsulation method is glass glue (Frit) encapsulation method, and this encapsulation method is very good for water and oxygen barrier properties. However, the glass glue encapsulation method has relatively high technological requirements, a...
