Problems solved by technology

In the traditional process, the mark point processing method is to process the sealing cover first, and then process the mark point. The main defect of this process is that the cover plate processing and mark processing point positioning have to be carried out twice, resulting in inaccurate mark point positioning. Marking accuracy is not high

Embodiment Construction

[0014] The method for processing the mark points of the sealing cover plate of the organic light emitting display of the present invention comprises the following steps:

[0015] ⑴ During the mask exposure process of the sealing cover, the Mark point positioning is realized while the size of the cover is positioned. The positioning method is to attach a positioning film substrate to the upper and lower surfaces of the sealing cover, and each positioning film substrate is The graphic size of the sealed cover plate and the relative position of the Mark point are marked. In this way, the positioning of the Mark point is realized.

[0016] ⑵ Place the exposed sealing cover on the machining center console, and align the drill bit with the Mark positioning point obtained in step ⑴.

[0017] (3) Start the machining center, the drill speed is 1700-2100 rpm, preferably 1800-1900 rpm, the drill angle is perpendicular to the sealing cover, and the running time is 2-4 seconds. Among the...

Abstract

The invention discloses a method for processing Mark points on a sealing cover plate of an organic light emitting display (OLED), belonging to the technical field of sealing of the OLED. In a mask exposure process of a sealing cover plate, the positioning of Mark points is realized at the same time when the dimension of the cover plate is positioned; and in the positioning method, the positioning of the Mark points is realized by respectively attaching a positioning film substrate on the upper surface and the lower surface of the sealing cover plate and respectively labeling the graph dimension of the sealing cover plate and the relative positions of the Mark points on both the positioning film substrates. In the method for processing the Mark points on the sealing cover plate of the OLED, the positioning and the exposure of the Mark points are simultaneously carrier out so as to greatly diminish the positioning errors, and thus, technological breakthroughs on clearness in labeling, accuracy in positioning, easiness for automatic recognition by a production line, and the like are realized, the processing time is shortened and the production efficiency is improved.

Description

technical field [0001] The invention discloses a method for processing Mark points of a sealing cover plate of an organic light emitting display, and belongs to the technical field of sealing of organic light emitting displays. Background technique [0002] The traditional organic light-emitting display sealing cover processing technology is divided into glass substrate cleaning, masking, protective film application, etching (including mask exposure process), mark point processing, stripping, finished product cleaning, inspection and other processes. [0003] Mark point is a necessary and important mark in the mass production of organic light emitting display (OLED). According to the mark point on the OLED sealing cover, the organic light emitting display (OLED) production line can automatically identify and align automatically. In the traditional process, the Mark point processing method is to process the sealing cover first, and then process the Mark point. The main defect...
