In this case, the 'line segments toward one direction' appear in the first direction and the 'line segments toward the other direction' appear in the second direction.

The second layer 205 is superimposed on the transparent ink pattern. The second layer 205 may be made of a transparent material such as a UV material or a urethane. The second layer 205 is made transparent so that the first pattern 202a of the first layer 202 is exposed to the outside.

The second layer 205 refracts the light reflected through the transparent ink pattern. Therefore, according to the embodiment of the present invention, the transparent ink pattern is not exposed in the thickness direction of the assembly (direction of stacking of the layers), and the transparent ink pattern can be identified in a direction deviated from the lamination direction by a certain angle.

According to the present invention, the transparent ink pattern is printed so as to have a thickness of not less than 10 μm and not more than 12 μm using a pearl coating rather than a simple solid color, and the second layer has a thickness of not less than 15 μm and not more than 18 μm As shown in FIG. When the thickness of the transparent ink pattern and the second layer exceeds the above range, the printed pattern is not seen and only the first pattern is seen, so that the object of the present invention can not be achieved. Therefore, accurate measurement of the thickness of the transparent ink pattern and the second layer is required.

6 is a conceptual diagram showing a transparent ink pattern of the present invention.

The battery cover 200 shown in FIG. 6 includes a mold member 201, a first layer 202, a coating layer 203, and a transparent pattern layer 204 stacked. That is, the second layer 205 is not laminated, and a transparent ink pattern is visible in the stacking direction.

Referring to FIG. 6, the battery cover 200 includes a small hexagonal first pattern 202a formed on the entire cover, and a transparent ink pattern forming 'LG' characters.

Before the second layer 205 is laminated, the transparent ink pattern is seen in the stacking direction of the layers. However, after the second layer 205 is laminated, the direction in which the light is reflected or refracted is changed, and the transparent ink pattern is seen in a direction deviating from the lamination direction of the second layer 205 by a certain angle. That is, by laminating the second layer 205, the transparent ink pattern becomes invisible in the stacking direction of the layers.

Fig. 6 is shown to look down in the overlap direction of the layers. The second layer 205 overlaps a part of the 'L' character among the transparent ink patterns. At this time, the transparent ink pattern of the portion overlapped with the second layer 205 is invisible. When the second layer 205 moves in the arrow direction, the remaining portion of the 'L' character and the 'G' character are also invisible.

FIG. 7 is a conceptual diagram showing that different patterns are revealed according to the angle of view.

According to one embodiment of the present invention, the transparent ink pattern is formed by a combination of lines oriented in one direction and a combination of lines oriented in the other direction. That is, the transparent ink pattern may include two different patterns. In the first direction, a first transparent pattern (LG) made of the 'line segments facing in one direction' appears in the first direction and a second transparent pattern (PRO) made of the 'line segments directed in the other direction' ) Appears.

According to another embodiment of the present invention, the battery cover 200 includes a mold member 201, a first layer 202, a coating layer 203, a first transparent pattern layer 204, a second layer 205 ), A second transparent pattern layer 204, and a third layer may be sequentially stacked.

The second transparent pattern layer 204 has a different pattern from the first transparent pattern layer 204. Referring to FIG. 7, the first transparent pattern layer 204 has the 'LG' shape and the second transparent pattern layer 204 has the 'PRO' shape. The first transparent pattern is composed of lines oriented in one direction and the second transparent pattern is composed of lines oriented in the other direction.

In addition, the first transparent pattern and the second transparent pattern may be formed of lines oriented in the same direction. The first transparent pattern appears in one direction and the second transparent pattern appears in the other direction because the direction of refraction of the light is changed through the second layer 205 and the third layer even if the lines are oriented in the same direction.

FIG. 8 is an exploded view showing that a transparent ink pattern related to the present invention is applied to a display portion of a terminal, and FIG. 9 is a sectional view of a multi-pattern assembly viewed through line A-A of FIG.

Referring to FIG. 8, a circuit board 182 is disposed inside the terminal body. The circuit board 182 may be mounted to the rear case 102 as shown or may be installed in a separate internal structure. The circuit board 182 may be configured as an example of a control unit for operating various functions of the mobile terminal 100. As shown in the figure, the first sound output unit 152, the first camera unit 121, and the like may be mounted on the circuit board 182.

A display unit for displaying information processed by the mobile terminal 100 is disposed on one side of the terminal body. The display unit may be arranged to occupy most of the front surface of the terminal main body. The display unit includes a display 151 and a window 155 covering the display 151. [

The mobile terminal 100 has a frame for receiving the display 151. In this embodiment, it is shown that the frame is formed of the front case 101 forming the outer appearance of the terminal body. In contrast to this figure, the frame may be formed as a separate internal structure different from the front case 101.

The front case 101 may have a seating portion 101a. The seating portion 101a is recessed on one surface of the front case 101 to provide space for the window 155 to be mounted. Holes 121a 'corresponding to the first camera unit 121 and sound holes 153a' corresponding to the first sound output unit 152 are formed in the seating part 101a. The acoustic hole 153a 'may be disposed adjacent to the side wall of the front case 101.

The window 155 is mounted on the seat portion 101a. The portion through which the light is transmitted in the window 155 may have an area corresponding to the display 151. Accordingly, the user can recognize the time information output from the display 151 from the outside.

The window 155 may be made of a material that can transmit light, for example, a light transmitting synthetic resin, a tempered glass, or the like. The window 155 is divided into a central region corresponding to the display 151 and an edge region surrounding the central region. The edge region is seated and supported on the seating portion 101a and overlapped with the multi-pattern assembly 158. [

8 and 9, the multi-pattern assembly 158 includes a base member 158a, a first layer 158b covering one side of the base member 158a, a first layer 158b covering the first layer 158b, A transparent pattern layer 204 formed on the coating layer 158c and a second layer 158d formed to cover the transparent pattern layer 204 and the like.

According to an embodiment of the present invention, the first layer 158b is disposed to cover one side of the base member 158a. A first pattern 202a is formed on the first layer 158b. The first pattern 202a may correspond to a normal battery cover 200 pattern. According to another embodiment of the present invention, the first layer 158b may be integrally formed with the base member 158a. In other words, the first pattern 158a may be made such that the first pattern 158a and the base member 158a do not have a boundary therebetween and the first pattern 202a is drawn on the base member 158a.

The first pattern 202a may be etched into the first layer 158b through a laser or may be drawn by cutting the surface of the first layer 158b through machining, Can be produced immediately.

A paint layer 158c is deposited on the first layer 158b to cover the first pattern 202a. The coating layer 158c is formed to have a high luminance. The coating layer 158c may be formed on the upper surface of the first layer 158b in such a manner that the metal is heated and evaporated at a high temperature to closely adhere metal with the vapor.

In order to further increase the brightness of the coating layer 158c, the coating layer 158c may be manufactured by a multi-deposition method. The coating layer 158c may be deposited to form a multilayer layer using a material such as tin (Sn) or aluminum (Al).

A transparent ink pattern is drawn on the painting layer 158c. The transparent ink pattern can be formed by gathering lines drawn in one direction. That is, according to an embodiment of the present invention, as shown in FIG. 4, a specific character is drawn by a combination of lines oriented in one direction.

The transparent ink pattern is made up of a combination of lines oriented in one direction, so that light is reflected in a specific direction. Therefore, the transparent ink pattern remains transparent and is not exposed to the eye, but appears when viewed in the specific direction.

The transparent ink pattern can be formed by a combination of lines oriented in one direction and a combination of lines oriented in the other direction. That is, the transparent ink pattern may include two different patterns. In this case, the 'line segments toward one direction' appear in the first direction and the 'line segments toward the other direction' appear in the second direction.

The second layer 158d is superimposed on the transparent ink pattern. The second layer 158d may be made of a transparent material such as a UV material or a urethane. The second layer 158d is made transparent so that the first pattern 202a of the first layer 158b is exposed to the outside.

The second layer 158d refracts the light reflected through the transparent ink pattern. Therefore, according to the embodiment of the present invention, the transparent ink pattern is not exposed in the thickness direction of the assembly (direction of stacking of the layers), and the transparent ink pattern can be identified in a direction deviated from the lamination direction by a certain angle.

According to another embodiment of the present invention, the second layer 158d may be replaced with a window.

Referring to FIG. 8, a groove may be formed on a side surface of the window 155, which is disposed facing the side wall of the front case 101 and forms an assembly gap. Since the sound generated from the first sound output unit 152 is emitted along the assembly gap 153a between the front case 101 and the window 155 according to the above structure, The appearance of the mobile terminal 100 can be simplified.

The display 151 is disposed on the back surface of the window 155 and accommodated in the front case 101 to constitute a display portion together with the window 155. [ The display 151 is electrically connected to the circuit board 182 and is configured to output time information under the control of the control unit. The display 151 may have an area corresponding to a portion through which the light of the window 155 is transmitted.

The touch sensor 157 may be disposed to cover the back surface of the key button portion 131 of the window 155 to detect a touch input to the pictorial portion. The touch sensor 157 may be configured to cover not only the edge area where the key button unit 131 is formed but also the center area, so that the touch sensor 157 can detect the touch input to the time information output through the display 151.

The touch sensor 157 is configured to convert a change in a voltage, an amount of charge, and the like occurring in a specific portion of the window 155 into an electrical input signal. The touch sensor 157 has transparency so that time information formed on the display 151 can be transmitted.

The touch sensor 157 may have a conductive pattern patterned in such a manner that a conductive material is deposited on the window 155 itself or on a separate film. As the conductive material, ITO (Indium Tin Oxide), CNT (Carbon Nano Tube), conductive polymer, In203, SnO2, Au and the like can be used.

The touch sensor 157 may be in the form of a film and attached to the back surface of the window 155. At this time, an adhesive layer for bonding the window 155 and the touch sensor 157 may be disposed therebetween. As the adhesive layer, OCA (Optical Clear Adhesive), SVR (Super View Resin), or the like may be used.

The above-described multi-pattern assembly and the mobile terminal 100 including the same are not limited to the configurations and the methods of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments are selectively As shown in FIG.
