Description

Technical Field

[0001] This application relates to the field of display module manufacturing, specifically to a display module easy-tear adhesive production apparatus and method for display module manufacturing. Background Technology

[0002] With the widespread application of display modules in electronic devices such as supermarket price tags, e-books, and mobile phones, the increased demand has placed new requirements on production efficiency.

[0003] The manufacturing process of display modules involves numerous steps. Before being assembled into a finished product and applied to the customer, many processes occur. If the screen is contaminated or subjected to impacts during these processes, the display module can easily be damaged. To protect the display module, a protective film is usually applied after it is manufactured. This protective film remains in place throughout production and distribution, and must be removed before reaching the customer.

[0004] In existing technologies, because both the protective film and the display module are flat, the protective film is usually tightly adhered, making it difficult to find a tear point when removing it, which is inconvenient for customers. In some cases, especially when there is adhesive on the edges of the protective film and the display module, it is not easy to peel off, and forceful tearing can easily damage it. Making the peeling process easy and smooth requires continuous improvement in production. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to avoid the shortcomings of the prior art in terms of poor user experience when removing the protective film on the display module.
