Problems solved by technology

However, after a period of time, the static electricity in this area dissipates, and turning on Demura will cause overfilling problems
In order to make the display panel free of static electricity at the location corresponding to the optical collection element during Demura, the current method is usually to place the display panel for a long time before Demura or to increase the alcohol wiping process. However, this greatly reduces the efficiency of Demura. Increased time and labor costs

Abstract

The embodiment of the invention discloses a foam, a manufacturing method of a display device and a display device, including a protective film, a first adhesive layer, a foam body layer and a second adhesive layer, the first adhesive layer is located on one side of the protective film, The foam body layer is located on the side of the first adhesive layer away from the protective film, and the second adhesive layer is located on the side of the foam body layer away from the first adhesive layer; the foam includes a first area, a second area and a third area, and the second area The second area separates the first area from the third area and is respectively adjacent to the first area and the third area; the foam body layer includes a first foam part located in the first area and a second foam located in the second area The cotton part, the third foam part located in the third area; the second foam part includes a hollow part and a first connection part. Thereby reducing the generation of static electricity and reducing the defect rate of Demura overfilling.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a foam, a method for manufacturing a display device and a display device. Background technique [0002] With the development of display technology, in order to achieve a higher screen-to-body ratio of the display panel, optical acquisition components (such as fingerprint identification modules, cameras, etc.) are generally placed in the display area. In order to prevent the service life of the display panel from being impacted or affected by external force, foam is usually pasted on the side of the display panel facing away from the light-emitting surface, so as to play a role of cushioning and protection. In order to achieve an effective combination of the display panel and the optical collection element, a hollow groove is provided on the foam at the position corresponding to the optical collection element, so as to ensure that the optical collection element can collect enough...
