Abstract

The present invention is an expanded structure which is mainly composed of at least one layer; in particular, the layer is a linear Finnel structure with a very small spacing, thereby effectively reducing the thickness of the edge-expanding structure, and at the same time Achieve a linear enlargement of the image of a screen, so that the image displayed on the screen has a borderless effect.

Description

Expanded structure

The present invention relates to the technical field of display devices, and more particularly to an expanded structure applied to a screen.

With the development and advancement of electronic technology, the screens of today's smart phones are pursuing larger and larger screens in response to the demands of more functions and consumers. At the same time, consumers do not want to have too large a body, which affects handheld operations. Smoothness and increased inconvenience in carrying.

Therefore, consumers and related companies are pursuing a larger screen and a higher proportion of the screen ratio (the ratio of the screen display size to the overall size of the mobile phone); however, the main components of the screen are: a cover glass layer, a touch sensor And a display layer, wherein the touch sensing layer and the display screen layer have a frame due to technical limitations. 1 is a cross-sectional view showing a conventional narrow-edge display. As shown in FIG. 1, the narrow-sided display 1' is mainly composed of a light-transmissive glass 11', a frame 12', and a display module 13'. composition. It is conceivable that when the user splicing a plurality of narrow-sided displays 1', there are obvious seams between the adjacent narrow-sided displays 1', which will affect the smoothness and overall feeling of the user's viewing. .

Therefore, how to effectively and conveniently bring the display to a borderless effect is a problem that the relevant industry is trying to solve. In view of this, the creator of the present invention has tried to research and invent, and finally developed an expanded structure of the present invention.

The present invention is an expanded structure which is mainly composed of at least one layer; in particular, the layer is a linear Finnel structure with a very small spacing, thereby effectively reducing the thickness of the edge-expanding structure, and at the same time Achieve a linear enlargement of the image of a screen, so that the image displayed on the screen has a borderless effect.

In order to achieve the above-mentioned main purpose of the present invention, the creator of the present invention provides an embodiment of the expanded structure, which is applied to a screen, and includes: at least one layer of a layer disposed on an edge of the screen and a Between the cover sheets, and having a linear Fresnel structure; wherein the enamel layer has a height of less than 500 micrometers (μm); and the ruthenium layer has a pitch of less than 500 micrometers (μm).

1 is a cross-sectional view showing a conventional narrow-edge display; FIG. 2 is a cross-sectional view showing a first embodiment of a flared structure of the present invention; and FIG. 3 is a schematic view showing a first embodiment of the expanded structure of the present invention; Figure 4 is a cross-sectional view showing a second embodiment of the expanded structure of the present invention; Figure 5 is a cross-sectional view showing a third embodiment of the expanded structure of the present invention.

In order to more clearly describe an expanded structure proposed by the present invention, a preferred embodiment of the present invention will be described in detail below with reference to the drawings.

First embodiment

Referring to Figure 2, there is shown a cross-sectional view of a first embodiment of a flared structure of the present invention. As shown in FIG. 2, the expanded structure 1 is applied to a screen 2, and mainly includes at least one layer 11 disposed between the edge of the screen 2 and a cover glass 3, and has a linear phenanthrene. A linear Fresnel structure; wherein the height of the ruthenium layer 11 is less than 500 micrometers (μm), and the pitch of the ruthenium layer 11 is less than 500 micrometers (μm). Referring to Figure 3, there is shown a schematic view of a first embodiment of the expanded structure of the present invention. It can be seen from FIG. 3 that the expanded structure 1 further includes an adhesive layer 1a disposed between the cover glass 3 and the enamel layer 11 for adhering the enamel layer 11 to the cover. On the glass 3. It should be noted that the adhesive layer 1a is a UV glue (ultraviolet light curing resin). Moreover, the enamel layer 11 is made of any one of the following: polymethylmethacrylate (PMMA), epoxy resin (Epoxy), thermoplastic polyurethane (TPU), polyurethane ( Polyurethane, PU), or Silicone.

Second embodiment

With continued reference to Figure 3, and also to Figure 4, a cross-sectional view of a second embodiment of the expanded structure of the present invention is shown. As shown in the figure, it can be seen that in the present embodiment, the flared structure 1 further includes a protective layer 12 disposed on the enamel layer 11 as compared with the first embodiment. The design is such that the expanded structure 1 is more durable when used. Moreover, the protective layer 12 is made of any one of the following: polymethylmethacrylate (PMMA), polyethylene terephthalate (PET), epoxy resin (Epoxy), thermoplastic Polyplastic Polyurethane (TPU), Polyurethane (PU), or Silica.

Third embodiment

With continued reference to Figure 2, and also to Figure 5, a cross-sectional view of a third embodiment of the expanded structure of the present invention is shown. As shown in the figure, it can be seen that in the present embodiment, the enamel layer 11 is formed on the cover glass 3 and located in the cover glass 3 and the screen 2 as compared with the first embodiment. between.

Thus, the above-mentioned system has completely and clearly explained the structure of all embodiments of the expanded structure of the present invention. From the above, we can know that the present invention has the following advantages:

(1) The expanded structure 1 of the present invention is effective in reducing the thickness of the expanded structure 1 by a layer having a linear Finnel structure, and simultaneously linearly magnifying the image of the screen 2 to Renders a borderless effect. In addition, there is no doubt that the use range is increased, that is, the structural thickness is increased and the process is difficult.

It must be emphasized that the above detailed description is specific to the possible embodiments of the present invention, but the embodiment is not intended to limit the scope of the patent of the present invention. Equivalent implementations or modifications that are within the spirit of the present invention are intended to be included in the scope of the patent.
