A display module and a bonding accuracy detection method

Abstract

The invention discloses a display module, comprising: a display panel, including an effective area and a wiring area; and a cover plate, including a visible area and a frame area; mark, each of at least one pair of light-sensitive luminous marks is a preset distance from the boundary line between the effective area and the routing area, and the preset distance is required by the bonding of the display panel and the cover plate. The fitting accuracy and the projection distance between the effective area and the visible area are determined, wherein the light-sensitive luminescent mark is set in the effective area and the distance between the edge of the light-sensitive luminescent mark far away from the dividing line and the dividing line is the fitting accuracy; or the light-sensitive The luminescent mark is arranged in the wiring area, and the distance between the edge of the light-sensitive luminescent mark and the boundary line close to the boundary line is the sum of the bonding accuracy and the projection distance. The invention can rapidly detect the lamination accuracy of the display module.

Description

Technical field [0001] TECHNICAL FIELD The present invention relates, more particularly to a bonding module and accuracy of the detection method of a display. Background technique [0002] With the technological development of the flexible display module, the display module frame module is more narrow, bonded to the display module accuracy requirements have become more sophisticated, present in the bonding process of the module (the display panel and the cover after bonding plate), is usually required to be bonded to the display module detection accuracy, it is determined whether the display panel and the deviation of the distance between the cover plate fit within the accuracy of the distance, in order to detect bonding accuracy required for the display module full inspection or sampling, and detection is often the way with artificial microscopic examination, however, it requires a lot of energy and time for staff members, inefficient and manual microscopic examination of the me...

Problems solved by technology

[0002] With the development of flexible display module technology, the frame of the display module is becoming narrower and narrower, and the requirements for the accuracy of display module bonding are getting higher and higher. At present, in the module bonding process (display panel and cover board bonding), it is usually necessary to test the bonding accuracy of the display module to determine whether the deviation distance between the display panel and the cover plate is within the bonding accuracy distance. In order to detect the bonding accuracy, the display module needs to be tested Sampling inspection or full inspection, and the detection method often uses manual microscope inspection, but this requires a lot of energy and time for the staff, the efficiency is low, and the detection method of manual microscope inspection is not convenient enough
