In this state, when the smart phone is turned on, an information screen of the smart phone is displayed. At this time, light exhibiting the information screen of the smartphone is seen by a user through transmitting a touch screen and atransparent member 110 having an image, that is, a transparent protective cover having an image, and animage coating layer 120 included in a back side of the transparent protective cover is not seen by a user through transmitting with the light of information screen, and the information screen is only seen by a user. Meanwhile, when the smartphone is turned off, there is no light exhibiting an information screen on the smartphone, so that external light is transmitted to the transparent protective cover and refraction-reflected by theimage coating layer 120. For this reason, in a state in which the smartphone is turned off, the image of theimage coating layer 120 is seen by a user. - As described above, in a case in which the transparent member having an image according to the present invention is a transparent cover of a touch screen of a smartphone, when the smartphone is turned on, an information screen of the smartphone is seen by a user through transmitting the transparent cover and an
image coating layer 120. At this time, theimage coating layer 120 included in a back side of the transparent cover is not seen by eyes of a user and the information screen is only seen by eyes of user through transmitting the light of the information screen. Meanwhile, when the smartphone is turned off, there is no light exhibiting an information screen on the smartphone, so that external light is transmitted to the transparent cover of the touch screen, and refraction-reflected by theimage coating layer 120. For this reason, in a state in which the smartphone is turned off, the image of theimage coating layer 120 is seen by a user. - As set forth above, according to exemplary embodiments of the invention, since an
image coating layer 120 is formed by using one part of the process for producing semiconductors, the production process is simple, and the production cost is low. - As described above, according to exemplary embodiments of the invention, a damage of an image is prevented when using IT devices, because an image having various shapes such as logos of manufacturer, texts, for example, a name of a user, and shapes of animals or human being, are not formed on the side in contact with a user, but included in an inner side surface.
- In addition, according to exemplary embodiments of the invention, since when IT devices are turned off, an image such as a logo or character are seen on the display area of IT devices, while when IT devices are turned on, the image such as a logo or character are not seen, but an information screen is only seen, a user does feel comfortable seeing the information screen, and also a user can feel a mysterious feeling and aesthetic effect. In addition, when the image is a logo of the manufacturer, a successful advertising can be obtained.
- While the present invention has been shown and described in connection with the exemplary embodiments, it will be apparent to those skilled in the art that modifications and variations can be made without departing from the spirit and scope of the invention as defined by the appended claims.
