DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display filter for an electronic device, and more particularly, to a display filter for an electronic device which can prevent a display surface of the electronic device from reflecting external light, thereby preventing an operator's eyes from being damaged. It concerns display filters.

[0002]

2. Description of the Related Art In recent years, with the introduction of computers and word processors due to the OA of office work, the display surface of these electronic devices reflects external light, causing adverse effects such as causing obstacles to workers' eyes. Giving it was a problem.

[0003] This means that not only does the display surface of these electronic devices reflect external light not only cause fatigue and haze in the eyes of workers, but also eventually impair eyesight, such as deterioration of vision. Things.

[0004] Therefore, as one method of improving the adverse effects of the display surface of these electronic devices, a mask made of a hard plastic plate is mounted on the display surface of the electronic devices. A method has been taken to prevent this.

However, according to such a conventional method, it is not possible to remove all of the adverse effects caused by the display surface of the electronic device, but only to remove a part thereof. Not only is it inevitable, but the progress of electronic devices is too early to respond, and there is no effective countermeasure.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, a main object of the present invention is to provide a filter which can be mounted on a display surface of an electronic device by using a specific structure, and It is an object of the present invention to provide a display filter for an electronic device, which can effectively prevent a display surface from reflecting external light and causing an adverse effect such as an obstacle to an operator's eyes.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a display filter for enhancing the usability of an electronic device by being attached to a display of the electronic device. This is achieved by providing a display filter for an electronic device, wherein a plurality of anti-reflection grooves and a plurality of anti-reflection grooves in the lateral direction are provided.

[0008]

As described above, according to the present invention, it is possible to effectively prevent a display surface of an electronic device from reflecting external light and causing an adverse effect such as an obstacle to an operator's eyes. Attaching a display filter of an electronic device having a large number of anti-reflection grooves and lateral anti-reflection grooves on the surface thereof to the display surface of the electronic device causes external light to be reflected and adversely affects the eyes of workers. Can be effectively prevented.

That is, by mounting the display filter of the electronic device according to the present invention on the display surface of the electronic device, when external light from above or behind sunlight or lighting is incident on the display surface of the electronic device, The upper external light and the rear external light impinge on the inclined surface of the antireflection groove in the lateral direction of the display filter and are reflected obliquely downward, thereby preventing the light from entering the eyes of the operator. Further, when the upper external light or the rear external light incident toward the display surface hits the radiation surface of the antireflection groove in the lateral direction of the display filter, the external light is reflected upward and enters the eyes of the worker. Will be blocked.

On the other hand, when side external light is incident on the display surface of the electronic device, such as when the electronic device is on the window side, the display filter of the electronic device according to the present invention is mounted on the display surface of the electronic device. By
When external light such as sunlight from the side or the rear enters the display surface of the electronic device, the external light or the rear external light impinges on the inclined surface of the vertical anti-reflection groove of the display filter and is reflected obliquely to the side. And is prevented from entering the eyes of the worker. Also, when the lateral external light or the rear external light incident toward the display surface hits the radiation surface of the vertical anti-reflection groove of the display filter, the external light is reflected laterally and may enter the eyes of the worker. Will be blocked. Therefore, by mounting the display filter of the electronic device according to the present invention on the display surface of the electronic device, external light such as sunlight or the like from above, from the side, or from the rear may enter the display surface of the electronic device. However, the upper external light, the lateral external light, or the rear external light impinges on the inclined surface or the radiation surface of the horizontal antireflection groove or the vertical antireflection groove of the display filter, and is reflected in an oblique direction (downward or lateral). Therefore, the light is prevented from entering the eyes of the worker, and external light is reflected on the display surface of the electronic device, so that the effect of preventing the bad influence on the eyes of the worker is almost perfect.

This impinges on a vertical anti-reflection groove 5 provided on the surface 3 of the light source 1 and is reflected laterally to prevent the lateral external light and the rear external light from entering the eyes of the operator. At this time, of the vertical antireflection grooves 5 provided on the surface 3 of the display filter 1 of the electronic device, a rightward inclined surface 8 inclined to the right and formed to the left from the center is provided from the left and rear. Is reflected on the right side and is prevented from entering the eyes of the operator from the left side and the rear side. Also,
Of the antireflection grooves 5 in the vertical direction, outside light from the right side or the rear shines on a leftward inclined surface 9 inclined to the left side formed on the right side from the center and is reflected to the left side. And outside light from behind is prevented from entering the operator's eyes. Furthermore,
Of the antireflection grooves 5 in the vertical direction, the left-right inclined surfaces 8,
When external light from the left and right sides and the rear strikes the vertical radiation surface 10 in the vertical direction that is continuous with the respective 9, the external light from the left and right sides and the rear is reflected by the left and right sides, respectively. From the eyes of others. Further, since the entire surface 3 of the display filter 1 of the electronic device is formed in a dark color such as black capable of absorbing external light, the external light from the left and right sides and the rear is absorbed by the dark color, Reflection of external light from the left and right sides and from the rear is greatly reduced.

Therefore, by mounting the display filter 1 of the electronic device according to the present invention on the display surface of the electronic device, external light, such as sunlight, from above, from the side, or from the rear is directed to the display surface 12 of the electronic device 11. Even when the light is incident on the display filter 1 of the electronic device, the upper external light, the left and right lateral external light or the rear external light
