The case 110 may have a structure that can cover a rear surface and a side surface of a cell phone (not shown) to be protected. For example, the case 110 may have the shape of a rectangular parallelepiped box with one side thereof opened, corresponding to the shape of the cellular phone.

The rectangular parallelepiped box-shaped case 110 may include a side surface portion 112 surrounding the side surface of the cellular phone, a rear surface portion 114 adhering to the rear surface of the cellular phone, and a rim portion 116 surrounding the cellular top surface portion . In particular, the rim 116 surrounds the upper surface of the cellular phone, thereby allowing the cellular phone to firmly engage with the cellular phone case 100 and also to fix the cellular phone so as not to escape from the cellular phone case 100 can do.

In the mobile phone protective case 100 of the present embodiment, the case 110 is not limited to a rectangular parallelepiped box shape and may have various structures. For example, the case may be formed in a structure having a rear portion that is in close contact with the rear surface of the cellular phone, and a latch portion to which the four vertexes of the cellular phone can be inserted and fixed. In addition, the case may have a structure in which only the rear portion exists, and such rear portion is bonded to the cellular phone through an adhesive tape or the like. Furthermore, the case may be formed in the same shape as the lid of the mobile phone, and may be coupled to the mobile phone instead of the lid of the mobile phone.

The case 110 may be formed of a material having flexibility in terms of protecting the cellular phone. For example, the case 110 may be formed using at least one of urethane resin, polycarbonate resin, silicone, leather, and leather (artificial leather). In the mobile phone protective case 100 of the present embodiment, the case 110 may be formed by applying urethane or PC injection molding, or leather or leather.

Although not shown, an antenna module having an antenna, for example, an NFC (Near Field Communication) antenna module may be incorporated in the rear portion 114 of the case 110. Which will be described in more detail in Figures 3 to 5.

The lid cover 130 rotates about the connecting portion 134, thereby covering or opening the liquid crystal portion of the cellular phone. The lid cover 130 may be formed of leather or leather. Of course, the material of the cover 130 is not limited to leather or leather. That is, the lid cover 130 may be formed of various materials capable of protecting the liquid crystal screen.

A plurality of open portions 132 may be formed on the top surface of the cover 130 so that the light emitting unit 122 may be exposed. In some cases, the upper surface of the lid cover 130 may be formed of a transparent material, and when the transparent cover 130 is formed of such a transparent material, light from the light emitter 122 may be seen through, .

The FPCB 120 may be embedded in the lid cover 130, and a plurality of light emitters 122 may be mounted on the FPCB 120. Here, the light emitting body 122 may be, for example, an LED chip or an LED lamp. The FPCB 120 may have a structure in which the light emitting unit 122 is mounted on the FPCB 120 and the FPCB 120 operates in a top emission mode so that the light emitting unit 122 can operate in a manner of emitting light to the upper surface of the cover 130 .

For reference, the FPCB 120 is a type of a printed circuit board (PCB) using an insulating substrate having flexibility, and is advantageous in that three-dimensional wiring can be performed and miniaturization and weight reduction can be achieved. Accordingly, it is widely used in small and medium sized electronic products such as mobile phones, digital cameras, notebook PCs, and camcorders.

Although a plurality of light emitting bodies 122 may be disposed, only one light emitting body 122 may be disposed. In addition, the illuminant 122 may be arranged to have a specific pattern, for example, a constellation such as the illustrated pit dullness or various patterns such as an animal or character popular with people. Further, by applying a 3D lens or the like to the background portion of the pattern of the light emitting body 122, that is, the upper surface of the cover 130 or the FPCB, the cellular phone protection case can be made more colorful and beautiful. Here, the 3D Lensel refers to a sheet that allows a two-dimensional image to be recognized as three-dimensional (3D), that is, a three-dimensional image using an optical lens. Sometimes called a 3D lenticular sheet.

2, the light emitter 122 is not visible on the lower surface of the cover 130, but a portion where the light emitter is positioned is indicated by a small dotted line in order to indicate the corresponding position.

The cellular phone protection case 100 of the present embodiment receives a signal through an antenna (not shown) disposed on the rear portion 114 of the case 110 when a phone or a character is turned on by a cellular phone, It is possible to turn on / off the light emitting body 122 on the FPCB 120 by transmitting the used power to the FPCB 120. [ Accordingly, even when the mobile phone is operated in a silent or vibration mode, the user can easily recognize that a call is received or characters or the like are received through light emission of the light emitting body 122.

Hereinafter, the operation of the antenna, the FPCB 120, the light emitting body 122 and the like will be described in more detail with reference to FIGS. 3 to 5.

FIG. 3 is a conceptual view schematically showing an illuminator pattern disposed on a cover cover of the mobile phone protective case of FIG. 1 and an antenna module disposed on a case bottom.

And is electrically connected to the light emitting body 122 mounted on the FPCB 120 through the wirings formed on the FPCB 120. In FIG. 3, the NFC antenna module 140 and the light emitting body 122 are directly connected through the wiring 150 for the sake of understanding. However, in reality, the NFC antenna module 140 is first connected to the input / output terminal (not shown) of the FPCB 120, and is connected to the light emitting body 122 through the wires formed in the FPCB 120.

For reference, NFC may refer to a technique of transmitting data between terminals at a close distance of 10 cm or less with a contactless short-range wireless communication module using a specific frequency, for example, a frequency band of 13.56 MHz as one kind of RFID. Such NFC technology can be widely used not only for payment but also for travel information transmission, transportation and access control locks for goods information and visitors in supermarkets and general shops.

In most cases, most of the mobile phones incorporate an NFC module in the rear portion thereof. In the mobile phone protection case 100 of the present embodiment, the signal from the NFC module disposed on the back of the mobile phone through the NFC antenna module 140 built in the case 110 , In particular a signal indicating that a telephone or a text has been received. Meanwhile, the NFC antenna module 140 according to the present embodiment can generate power using the received radio wave, and can turn on a light emitting device, for example, an LED lamp using such power source. For reference, a module built in the case 110 is also referred to as an NFC module. Herein, the reception side using the antenna is emphasized to be referred to as an NFC antenna module.

Although the NFC antenna module 140 is illustrated as being very small in the drawing, the NFC antenna module 140 may be disposed over the entire surface of the case 110 in view of increasing signal detection and power generation efficiency. For example, the NFC antenna module 140 may include a loop antenna, an RF chip on board (COB), a condenser, a diode, and the like, and a loop antenna receiving the signal may be formed across the entire surface of the case 110 . In some cases, only a loop antenna is disposed on the bottom surface of the case 110, and RF COBs, capacitors, diodes, and the like may be disposed on the FPCB 120.

The operation of the cellular phone protection case 100 according to the present embodiment will be briefly described. When an incoming call is received or a character is received, the NFC module in the cellular phone operates to generate a signal, And the FPCB 120 applies the received power to the light emitting body 122 to receive the light emitted from the light emitting body 122. The light emitted from the light emitting body 122 is transmitted to the FPCB 120 through the NFC antenna module 140, On / off operation.

The FPCB 120 may directly apply the power from the NFC antenna module 140 to the light emitting body 122 to turn on the light emitting body 122 but may alternatively turn on the light emitting body 122 through another method, . For example, the FPCB 120 may further include a controller circuit (not shown), and such a controller circuit may control ON / OFF of the light emitting body 122. [

When the control unit circuit is used, the light emitting body 122 can emit light with various rules. For example, when the light emitters 122 are arranged in a pit pattern as shown in the drawing, the light emitters may be sequentially turned on or off from above or below. Alternatively, the light emitters may emit light with various rules such that the odd-numbered emitters and the even-numbered emitters flicker alternately.
