Description

Light Case External Case for Light Emitting NFC Terminal {LIGHT EMITTING CASE BY LIGHT GUIDE PLATE FOR NFC}

The present invention relates to an external case of a mobile terminal, and more particularly, includes a light emitting member in an auxiliary case overlaid on the outside of the mobile terminal, and emits light without a separate battery and controller configuration according to the NFC activation signal of the mobile terminal. This is possible, but the light guide plate emitting type NFC to perform a variety of beautiful aesthetics and functions by allowing the emitted light to be emitted in a variety of shapes and shapes represented by the light guide plate provided therein, instead of being directly expressed directly to the outside. A light emitting outer case for a terminal.

Recently, portable terminals such as smart phones, tablet PCs, notebook PCs, PDAs, etc. are designed and released to have a thinner thickness. In addition, these portable terminals include a large number of precision parts inside them to perform a small, thin, high and various functions, and a large portion of the display panel is required to meet the trend of larger screens.

Therefore, the external rigidity of the portable terminal for protecting each internal component is important, and it is common to add an external auxiliary case made of synthetic resin on the outside to reinforce the strength of its own case. The outer case has a function of protecting the inner portable terminal from external shocks and scratches and improving grip, and at the same time, expressing a monotonous shape and design of the portable terminal in various shapes and designs.

Recently, a case has been found in which an LED lamp is coupled to an outer case to cause the lamp to blink at a specific time, such as during a telephone call.

1 is a view showing a configuration of a conventional light emitting outer case. 1, in a conventional light emitting outer case, when a reception signal is applied to the cellular phone 1, a radio wave generated from the cellular phone is detected by the radio wave reception sensor 2, and the detected reception signal is supplied to the microcontroller 3 When the intensity of the signal is different from that of the reference signal, the microcontroller 3 electrically applies the current from the battery 4 through the switch-on control so that the light emitting member 6 emits light. At this time, the mobile phone battery 5 is also used as a power source.

The prior art is a method of sensing a mobile phone incoming signal itself by a sensor, requires a control means such as a micro-colroller, and also uses the power of the battery. Such a structure emits light during telephone transmission and reception, and a microcomputer chip for control must be configured in a circuit, and a separate power source is required.

Accordingly, the present applicant has devised an improvement technique as shown in FIG. 2, but the biggest difference is that the proximity signal of the mobile terminal 1 including the NFC function is used as the object of light emission, not detecting the incoming call signal. will be.

2, the portable terminal 1 is provided with a loop antenna coil 10 for performing the NFC function. NFC, or Near Field Communication, is a non-contact short-range wireless communication module that uses 13.56Mhz frequency band as one of RFID and transmits data between terminals at a distance of about 10cm.It is not only payment but also market, travel information, traffic, and access control. , A lock device and the like are widely used, and the portable terminal 1 equipped with this function has recently been released.

The antenna coil 10 may be provided on the cover side of the mobile terminal 1 or surrounded by the outside of the battery, but is not limited thereto. The antenna coil 10 of the mobile terminal 1 may be set to be activated when a telephone call is transmitted or received, or may be activated when communicating between P2P devices with another smartphone or PC, or may be attached to a reader to which an RFID tag is attached. It can be activated at close proximity or at the time of E-commerce authentication or payment as a card emulation. That is, instead of sensing the call signal of the portable terminal 1, a method of receiving induction power by the loop antenna coil 10 of the portable terminal 1 which is activated separately upon reception of the call signal is utilized. This setting will be selectable in the application, app or option menu on the NFC terminal. In addition, by adjusting the NFC output using the app, it is possible to adjust the light emitting frequency of the light emitting device, for example, to increase the flicker when the incoming signal.

At this time, an induction current is also generated in the induction wire 24 of the outer case 20 arranged in a similar manner facing the antenna coil 10 that is activated, and thus light is also generated in the light emitting member 22. At this time, the light emitting operation can be performed without any control of the controller or supply of battery power.

As a result, the light emitting outer case has a light emitting function without a separate power source or a controller, and the parts are simplified to reduce production costs, facilitate production, and significantly reduce defects or failures.

However, since the external case is only localized point emission through a point light source, there is a disadvantage in that there is a limit in the expression and expressive power of light depending on the arrangement of the light emitting device. However, there is a problem in that the number of light emitting devices to increase the number of light emitting devices for the purpose of various light emission and expression is complicated in the manufacturing process, it is limited to express the appearance having a more diverse and beautiful aesthetic.
