Description

Appearance board

The present invention relates to an appearance panel, and more particularly to an appearance panel having a quasi-photonic crystal structure for being disposed on an information display window of a device.

Generally, electronic devices such as mobile phones, tablets, monitors, and the like display information on the screen for the user to view, but the panel of the screen is usually reflective, especially the light reflected by the sunlight may seriously interfere with the line of sight, and the screen display may not be clearly seen. Message. In order to avoid reflected light from interfering with the line of sight, it is common practice to plate a multi-layer anti-reflection film on the panel or use surface atomization to scatter glare.

However, the existing methods for improving the reflected light have their own disadvantages. In the case of plating a multi-layer anti-reflection film, an anti-reflection film can only destroy light of a specific wavelength and light of a wavelength close thereto. For example, the visible light of the human eye can be roughly divided into "red, orange, yellow, green, blue, enamel, purple". If it is an anti-reflective film for green light, the anti-reflection effect on yellow, green and blue is better. Ok, but there is still a lot of reflection on red and purple light. Although it is possible to plate a multi-layer anti-reflection film to destroy reflected light of various wavelengths, the process is complicated and expensive, and there is no way to uniformly weaken the light of various colors. Surface atomization allows glare to disperse In terms of the method of shooting, there is a direct disadvantage that the surface of the panel looks foggy and the transmittance of light decreases.

In addition to the problem that the screen of the electronic device has reflected light to interfere with the line of sight, a device generally having an information display window, such as a clock, is usually covered with transparent glass, and the surface of the glass also reflects light and interferes with the line of sight.

As described above, the conventional device with an information display window usually has a problem that reflected light interferes with the line of sight, and how to effectively reduce the reflected light is an object that needs improvement.

Therefore, the object of the present invention is to provide an appearance panel which can effectively reduce the reflectance for setting in an information display window of a device.

Thus, the novel appearance panel is disposed in an information display window of a device for allowing a user to view information displayed by the device through the appearance panel. The appearance panel has: a panel body and a body formed on the panel body A quasi-photonic crystal structure for the side surface, the quasi-photonic crystal structure being disposed toward the user, and reducing the reflection of light in the environment to the user's eyes when the user views the information displayed by the device.

The appearance board of the present invention, wherein the quasi-photonic crystal structure is formed by an array of a plurality of studs and the array arrangement has at least twelve-fold symmetry.

The appearance board of the present invention, wherein the quasi-photonic crystal structure has a period of 50-1000 nm, preferably 200-350 nm.

The appearance board of the present invention, wherein the quasi-photonic crystal junction The height of the studs is between 50 and 2000 nm, preferably between 300 and 500 nm.

In the appearance board of the present invention, the top end of the pillar of the quasi-photonic crystal structure is tapered.

The novel effect board has a quasi-photonic crystal structure, can effectively reduce the reflectance, and has excellent anti-reflection effect, and is suitable for being disposed in the information display window of the device to reduce the reflection of light in the environment to the eyes of the user. To avoid disturbing the line of sight.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 and FIG. 2, a preferred embodiment of the present invention 1 is configured to be disposed in an information display window 101 of a device 100 such that a user (not shown) views the device through the appearance panel 1. 100 shows the information. In this embodiment, the device 100 is exemplified by a tablet computer, and the device may also be a device having an information display window, such as a mobile phone, a display, a clock, a watch, etc., and is not limited to the embodiment.

The appearance board 1 has a board body 11 and a quasi-photonic crystal structure 12 formed on one side of the board body 11. In the present embodiment, the quasi-photonic crystal structure 12 is formed by an array of a plurality of studs 121, and the array arrangement has twelve-fold symmetry (see FIG. 3). It can also be designed as a highly symmetrical structure of a symmetrical square-triangle lattice of more than twelve weights. The period d of the quasi-photonic crystal structure 12, that is, the distance between the central axes of two adjacent protrusions 121, may be between 50 and 1000 nm, and the height h of the protrusions may be between 50 and 2000 nm. The quasi-photonic crystal structure 12 is configured to be disposed toward the user, and can reduce the reflection of light in the environment into the user's eyes when the user views the information displayed by the device 100. That is, when the appearance panel 1 is disposed on the device 100, the quasi-photonic crystal structure 12 is outwardly located on the surface of the device 100, so that light in the environment is first incident on the quasi-photonic crystal structure 12, Photonic crystal junction The structure 12 increases the transmittance of light entering the plate body 11 at different angles, thereby reducing light reflection and achieving an anti-reflection effect. Further explanation is as follows.

4 to FIG. 9 are the reflectance (R%) of the incident photon crystal structure 12 with the visible light wavelength of 550 nm as the GD-CALC software simulation analysis, wherein FIG. 4 shows the formation of the pillars 121 having a substantially cylindrical shape.

The quasi-photonic crystal structure 12 formed by the tapered pyramid 121 is shaped, and FIG. 9 is the reflectance corresponding to the quasi-photonic crystal structure 12 shown in FIG. 8 under different periods d and different pillar heights h (R%). ).

5, 7, and 9, the period d of the quasi-photonic crystal structure 12 is preferably between 200 and 350 nm, and the height of the stud 121 is between 300 and 500 nm, which can have a better effect of reducing the reflectance and making the reflection The rate can be less than 1%. Further, by the shape comparison of the studs 121, the tips of the studs 121 shown in FIG. 4 are flat, and the tips of the studs 12 shown in FIGS. 6 and 8 are tapered, and the convexities are shown in comparison with FIGS. 5, 7, and 9. The tip of the post 12 tapers to have a lower reflectivity, i.e., has a better anti-reflective effect.

The material of the appearance panel 1 of the present embodiment can be selected according to the use requirements, such as enamel, sapphire, glass, etc., and generally has sufficient strength and transparency to clearly see the displayed information. Moreover, the quasi-photonic crystal structure 12 can be processed by a nano imprint process or an E-beam process. The quasi-photonic crystal pattern is transferred to the surface of the board body 11 to be formed.

In summary, the novel appearance panel 1 has a quasi-photonic crystal structure 12, which can effectively reduce the reflectivity, and has an excellent anti-reflection effect, and is suitable for being disposed in the information display window 101 of the device 100 to reduce light reflection in the environment.
