[0002] PET (polyethylene terephthalate) is a flexible substrate material characterized by its thinness, transparency, flexibility, and chemical resistance, making it suitable as a substrate or surface protective film for electronic ink displays. In electronic paper manufacturing, PET is often used as a carrier for transparent conductive films or combined with optical adhesives to form a protective layer to enhance the screen's scratch resistance. As a flexible substrate, its low surface roughness and high light transmittance help optimize the clarity and durability of electronic ink displays.
[0003] FPL (electronic paper film) is the core display layer of electronic paper, which is composed of electronic ink microcapsules, transparent electrodes, etc., and is directly responsible for realizing the electrophoretic display effect of electronic ink.
[0004] The FPL is typically laminated with other materials, such as a flexible substrate and a PS (polystyrene) protective film, to form a multi-layered electronic paper display. The FPL (electronic paper film) can also include a driver circuit (IC) and a flexible printed circuit board (FPC).

[0034] like Figure 1 The overall electronic paper nail cover module includes multiple electronic paper nail cover modules.
[0035] like Figure 2 and Figure 3 , an electronic paper nail cover production process component, including: two or more electronic paper nail cover modules; Figure 2 The electronic paper nail cover module includes a flexible base PET layer, an electronic paper film FPL, and a transparent protective layer; the electronic paper film FPL is on the flexible base PET layer, and the transparent protective layer is on the electronic paper film FPL.
[0036] like Figure 3 The flexible base PET layer includes a test point, which is connected to the circuit electrical signal in the electronic paper film FPL.
[0037] like Figure 4 During the production process, the test probe of the production test device is connected to the test point by electrical signals, and the production test device drives the electronic paper nail cover module to display the test pattern.
[0038] like Figure 3 and Figure 4 , the test point is electrically connected to two or more electronic paper nail modules; during the production process, the test probe of the production test device is electrically connected to the test point, and the production test device drives the electronic paper nail module connected to the electrical signal to display the test pattern.
[0039] like Figure 1 The electronic paper nail modules are arranged in M rows and N columns, where M is greater than 2 and N is greater than 2. Each column may include a test point that is in electrical signal communication with the electronic paper nail modules in that column. Each row may include a test point that is in electrical signal communication with the electronic paper nail modules in that row.
[0040] like Figure 1 The arrangement direction of the electronic paper nail cover modules in each column is consistent, and the arrangement directions of adjacent columns differ by 180 degrees.
[0041] An embodiment of a method for producing an electronic paper nail cap includes the following steps: Step A: producing a flexible substrate PET layer, setting two or more electronic paper nail cap module positions on the flexible substrate PET sheet, setting a test circuit and a test point on the flexible substrate PET layer, wherein the test point is electrically connected to at least two electronic paper nail cap module positions; Step B: producing an electronic paper membrane FPL, setting two or more electronic paper nail cap module positions on the electronic paper membrane FPL sheet, setting a test circuit on the electronic paper membrane FPL layer, wherein the test circuit corresponds to the test point position of the flexible substrate PET layer; Step C: laminating the flexible substrate PET layer and the electronic paper membrane FPL layer accordingly; forming the above-mentioned electronic paper nail cap production process component; Step D: placing the production process component on a production test device; Step E: the production test device driving the production process component to display a test pattern; Step F: taking a photo to identify an electronic paper nail cap module with abnormal display; and Step G: cutting the electronic paper nail cap module according to the designed electronic paper nail cap module edge and discarding the electronic paper nail cap module with abnormal display.
[0042] Step C includes step C11, after the flexible base PET layer and the electronic paper film FPL layer are correspondingly laminated, a transparent protective layer is laminated on the electronic paper film FPL layer.

In some embodiments, the production test device includes multiple rows or columns of test probes, which drive multiple rows or columns of the electronic paper nail module to display a pattern at a time.
[0045] Prior art uses a single-piece attachment method to produce and test e-paper nail modules. However, due to the module's relatively small size, this method results in low production efficiency. The relevant production efficiency data for prior art is as follows: cutting PET into single-piece product sizes (capacity 2,500 pieces / hour); cutting FPL into single-piece product sizes (capacity 2,500 pieces / hour); attaching PET and FPL together (capacity 150 pieces / hour / person); and functionally testing the attached product (capacity 200 pieces / hour / person).

The electronic paper is cut to the same size as the PET and attached to the surface. Functionality testing is then performed directly on all products using test points on the bottom of the PET. After testing, the products are laser-cut to the individual product dimensions for subsequent fabrication.
[0047] The technical solution in this application has the following production efficiency data: cutting FPL into PET size (capacity 24,000+ pcs / hour); attaching PET and FPL together (capacity 8,000+ pcs / hour / person); functional testing all attached products (capacity 8,000+ pcs / hour / person); laser-cutting the functionally tested products into single-piece sizes (capacity 2,500 pcs / hour / person). In particular, the efficiency of both the attachment production and testing processes has increased by more than tenfold.
[0048] In the electronic paper nail cover production method and process components of the present application, more than two electronic paper nail cover module positions are set on the flexible base PET plate, and test circuits and test points are set on the flexible base PET layer, and the test points are electrically connected to at least two electronic paper nail cover module positions; more than two electronic paper nail cover module positions are set on the electronic paper membrane FPL plate, and a test circuit is set on the electronic paper membrane FPL layer, and the test circuits correspond to the test point positions of the flexible base PET layer; the flexible base PET layer and the electronic paper membrane FPL layer are correspondingly bonded to form an electronic paper nail cover production process component; it is placed on a production test device; the production test device drives the production process component to display a test pattern; a photo is taken to identify the electronic paper nail cover module with abnormal display; the electronic paper nail cover module is cut according to the designed electronic paper nail cover module edge, and the electronic paper nail cover module with abnormal display is discarded.
[0049] As shown in the accompanying drawings, the above are only embodiments of the present invention and are not intended to limit the patent scope of the present invention.
