Abstract

The utility model relates to a decorative panel with a light adjustment function. The decorative panel with the light adjustment function comprises a carrier, a polarizing plate arranged on the carrier, and a decorative layer arranged on the polarizing plate. An ink layer is formed around the lower surface of the decorative layer. When the decorative panel is installed at the front end of a display device, the ink layer corresponds to a non-visible area around the display device. The polarizing plate is arranged so that the color of the non-ink layer area on the decorative panel under natural light has a low contrast with the color of the ink layer. Therefore, when the backlight source of the display device is in a closed state, the screen color of the display device will be consistent.

Description

Decorative panel with light adjustment function

technical field

The utility model relates to a decorative panel, in particular to a decorative panel applied to electronic products with liquid crystal screens.

Background technique

Generally, for electronic products with operation screen display, such as mobile phones, a layer of ink is usually coated on the periphery of the panel of the display device to cover the part of the non-visible area on the panel, so as to make the overall picture more beautiful. Usually it is the wiring layout area of the panel or other unnecessary exposed structures.

However, when the ink layer of the panel and the visible area it surrounds are in a standby or closed state, that is, when the backlight module is not emitting light, the picture pattern in the visible area is still clearly visible under the projection of external light. See, so the visible area and the ink layer cannot be integrated in appearance, and can be easily distinguished from the color difference, which will make the contrast effect of the screen under the two states of the product turned off and in use not significant enough.

In order to improve, some manufacturers first form a mirror coating on the top and bottom of the display device of electronic products, and then set the ink layer, and use the mirror coating to reflect most of the external light, so that the visible area and the ink layer are in the standby state. However, the lack of this method is that in addition to reflecting external light, the mirror coating will also affect the light penetration of the backlight module of the electronic product, which reduces the display brightness of the electronic product and must enhance the luminescence of the backlight module Brightness, resulting in accelerated power consumption of electronic products; and the degree of improvement of the mirror coating is limited, and the visual effect provided by the overall interface is still insufficient.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a decorative panel with light adjustment function, which can make the ink layer and the surrounding visible area blend together in color appearance.

In order to achieve the above purpose, the technical means used in the utility model is to provide a decorative panel with light adjustment function, which is installed on the front end of a display device. The display device has a visible area and a non-visible area. The trim panel for tweaking features contains:

a carrier;

a polarizing plate is provided on the carrier; and

A decorative layer is arranged on the polarizing plate, the lower surface of the decorative layer is an ink layer corresponding to a non-visible area of a display device, and the non-ink layer area of the decorative layer passes through the aforementioned polarizing plate to filter light in natural light The color shown below is consistent with the color of the ink layer.

The beneficial effect of the utility model is that when the decorative panel is installed on the front end of a display device of an electronic product, the non-visible area of the display device is covered by its ink layer, and the external natural light is filtered through the setting of the polarizer, so when the electronic product After the backlight of the product is turned off, the color presented in the non-ink layer area will be consistent with the color of the ink layer itself under natural light, and the contrast between the non-visible area and the visible area around the screen is extremely low, so when the machine is turned off or in standby The color of the screen of the display device in this state is consistent, which relatively makes the contrast effect of the electronic product when the backlight is turned on is more remarkable.

Detailed ways

The decorative panel with light adjustment function of the utility model is installed at the front end of a display device. The display device has a visible area and a non-visible area. Please refer to Figure 1 and Figure 2, which is the light adjustment function of the utility model. An exploded perspective view and a cross-sectional view of a preferred embodiment of the decorative panel include a carrier 10 , a polarizer 20 and a decorative layer 30 .

The carrier 10 can be a separate substrate, or can be a touch device so that the decorative panel of the present invention has a touch function.

The polarizer 20 is disposed on the carrier 10 to filter external light. In this embodiment, the polarizer 20 is adhered to the carrier 10 by optical glue 100 .

The decoration layer 30 is disposed on the polarizer 20 , wherein the lower surface of the decoration layer 30 corresponds to the non-visible area of the display device to form an ink layer 31 .

In order to reduce the reflection of external light, this embodiment further includes an anti-reflection plate 40 disposed on the decoration layer 30 .

Alternatively, the surface of the decoration layer 30 can be further processed to form an anti-reflection surface to reduce the reflection of external light. The anti-reflection treatment can form an anti-reflection coating on the upper surface of the decoration layer 30 .

Please refer to Figure 3, Figure 4 and Figure 5 for further cooperation. When the aforementioned carrier 10 is a touch device, its detailed structure may include:

The lower conductive layer 11 has a conductive line 110 formed on the periphery of its upper surface. The lower conductive layer 11 is conductive glass, such as indium tin oxide conductive glass (Indium Tin Oxide Conductive Glass), but not made of indium tin oxide conductive glass. For example, as shown in FIG. 5, the lower conductive layer 11 can also be made of a substrate 11A and a conductive film 11B disposed on the substrate 11A through an optical glue 111. For example, the conductive film can be an indium tin oxide conductive film, But not limited to indium tin oxide conductive film; the substrate 11A can be a plastic or glass substrate, but not limited to these two substrates;

An upper conductive layer 12 is located above the lower conductive layer 11 and on the lower surface of the aforementioned polarizer 20. The lower surface periphery of the upper conductive layer 12 also forms a conductive circuit 120. The upper conductive layer 20 can be an indium tin oxide conductive film; and

A gap layer 13, located between the lower conductive layer 11 and the upper conductive layer 12, the gap layer 13 includes a plurality of spacers (Dot Spacers) 130 and double-sided adhesive tape 131 that is located at the periphery and surrounds the spacers 130 , the double-sided adhesive tape 131 adheres the upper conductive layer 12 and the lower conductive layer 11 .
