BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly, to a mobile phone that can be displayed on a keypad capable of displaying numbers and letters by a combination of numeric key and function key buttons on the keypad.

In general, a mobile phone is a phone that can randomly move within a mobile communication area and talk to a general subscriber or another mobile phone through a base station. Like a car phone, a mobile phone randomly moves a base station in a wireless zone. It is a term used to refer to a general telephone subscriber or another mobile communication telephone subscriber and can be called by various names such as a mobile phone, a mobile phone, a wireless mobile phone, a wireless mobile phone, and a pocket phone.

Initially, mobile phones also used analogue methods, but they are expensive to maintain and their capacity is low. Currently, digital phones using code division multiple access (CDMA) are the dominant type. In addition, mobile phones with improved performance have been introduced every day, such as PCS (Personal Mobile Communication) phones, which use the same code division multiple access method but have higher frequency bands than ordinary digital mobile phones. have.

The principle is that when a person in the mobile communication area calls with a mobile phone, the wireless base station is first connected wirelessly, and when it leaves the area, the mobile station automatically switches to the next base station. The user can hardly notice the change because the base station changes time very short.

That is, there are a large number of wireless zones in the mobile communication service area, and there are wireless base stations for each wireless zone, so that the base station and the mobile phone are wirelessly connected. In addition, when connecting with a general subscriber, the wireless network is connected to a base station, and then a call is made through a control station or an exchange station through a wire.

In the early days when mobile phones began to be developed, there were disadvantages of being affected by the topography of buildings and mountainous areas.However, since 2000, manufacturing technology has developed so rapidly that these disadvantages are almost overcome. In addition to voice calls, you can leave texts on the LCD screen, and voice recognition phones that extract and memorize the features of the voice and find the closest to the features of the voice next time and make a phone call have appeared. In addition, mobile phones that fully implement alarm functions, traffic and securities information, and even videos have appeared, and as the functions become more diverse, the cost of mobile phones increases.

Hereinafter, a general mobile phone will be described with reference to the accompanying drawings.

1 is a view showing a typical mobile phone.

As shown in FIG. 1, a general mobile phone has a folder part 1 composed of a display part 2 for displaying a character or an image, a sign language part 3 for outputting a sound signal, and a number or character input. The mobile phone main body 14, which is composed of the keypad 5 and the talker 6 for inputting sound signals, can be broadly divided.

The display unit 2 provides functions for checking incoming / outgoing numbers and various menu screens.

However, in the manufacture of such a general mobile phone, only the display unit occupies up to 25% or more of the material cost of the mobile phone, which is causing a material cost increase.

In addition, there is a problem in the silver generation or the kids generation that they need to purchase an expensive mobile phone only for the purpose of a minimum call even though they do not feel the necessity and necessity of providing video information including traffic and stock information.

In addition, due to the miniaturization of mobile phones, it is true that the buttons of the keypad are difficult for the silver generation.

Accordingly, an object of the present invention is to provide a mobile phone that can be displayed on a keypad capable of designing a mobile phone of low cost and various designs at the same time displaying numerals and letters on a keypad to solve the above problems.

A feature of the present invention for achieving the above object is a main body, a transmitter / receiver unit provided at any part of the front and bottom of the main body, and a keypad unit provided between the transmitter / receiver unit and displaying incoming / outgoing signals. It is configured to include.

Preferably, the keypad unit is composed of numeric keys and function keys.

The display of the incoming / outgoing signal is performed by a combination of numeric keys and function keys of the keypad.

The incoming / outgoing signal is characterized in that the number, caller number or letter.

And, the display of the incoming signal is characterized in that the caller number or letter is roll-played.

In addition, the display of the outgoing signal is displayed each time a receiver number or character is input, and when the receiver number or character is input, the input receiver number or character is roll-played.

Hereinafter, a mobile phone that can be displayed on a keypad according to the present invention will be described with reference to the accompanying drawings.

2 is a view showing a mobile phone displayable on the keypad according to the present invention.

As shown in FIG. 2, a configuration of a mobile phone that can be displayed on a keypad according to the present invention includes a main body 10 and a receiver 11 provided at an arbitrary portion of an upper front of the main body 10 to output a sound signal. The receiver 12 is provided at an arbitrary portion of the front lower end of the main body 10 and is provided between the receiver 11 and the transmitter 12 for inputting a sound signal, and inputs or receives a signal. It consists of a keypad 13 for displaying a signal.

Here, the keypad portion 13 is formed between a circuit board, a dome switch located above the circuit board, the circuit board and the dome switch, and a thin film EL lamp (Electro Luminescent lamp) for providing backlighting and the dome. It has a number of keys that press the switch.

The circuit board is made of a rigid flexible wiring board (FPC) commonly used to be bent freely, the upper surface of the circuit board is formed with a fixed contact formed in the same direction as the central axis of each key.

The spacer is bonded to the upper side of the circuit board, and the spacer is formed of an adhesive layer coated with an adhesive on both sides thereof and has a certain thickness, and a plurality of grooves are formed in the same arrangement as the arrangement of the keys.

That is, the fixed contact of the circuit board is located in the spacer and the groove.

A sheet-shaped LED lamp or an EL lamp is bonded to the upper side of the spacer. If the EL lamp is bonded, a conductive moving contact is formed on the bottom of the EL lamp to maintain a predetermined distance from the fixed contact located in the groove formed in the spacer. The movable contact is positioned in one state.

The above-described EL lamps are used in instrument panels such as aircrafts, and when an electric field is applied, electrons and holes are recombined to make surface emission.

And since the EL lamp is made of a thin film type, it is possible to minimize the installation space rather than the LED lamp applied for backlighting.

In addition, the above-described EL lamps can be assembled by simply attaching them in a sheet shape, so that the assembly time of the keypad can be greatly shortened.

The dome switch is bonded to the upper side of the EL lamp, and the dome switch is composed of a sheet-shaped flat part made of a single body and a dome protruding upward from the flat part.

The dome may be made of a material having a predetermined elastic force and having the same arrangement as that of the same key.

Above the dome switch is a sheet-shaped key formed of a thin and transparent synthetic resin film, which is a printed surface on which a number or letter is printed, and a contact portion directly contacted by a finger for generating a signal. It is comprised by the processus | protrusion formed in the outer peripheral part of this contact part.

The central portion of the contact portion is located on the same axis as the central portion of the dome, and is partitioned so that the region of the contact portion can be accurately known by the projection.

As such, when the keypad 13 is manufactured in a thin film form using the keypad film, the thickness of the keypad can be minimized, thereby making it possible to manufacture a slim mobile phone that is easy to carry and use.

The keypad unit 13 manufactured as described above is described as an example and may be manufactured by another method.

Subsequently, the display operation in the keypad unit 13 according to the present invention, first, the keypad unit 13 is composed of a combination of numeric keys and function keys. Is roll-played and displayed on the keypad unit 13.

For example, if the caller ID is "010-123-4567", the keypad 13 will display ... → 7 → 0 → 1 → 0 → 1 → 2 → 3 → 4 → 5 → 6 → 7 → 0. → 1 → 0 → ... is rolled and displayed.

On the other hand, when a call connection request (outgoing) is attempted to reach an arbitrary mobile phone from the user's mobile phone, the receiver number or letters are displayed each time they are input. Or characters are roll-played and displayed on the keypad unit 13.

For example, when the recipient number is "010-321-4567", when the numeric key "0" of the keypad 13 is pressed, "0" is displayed by the combination of the numeric and function keys of the keypad 13. When "1" is pressed, the numeric and function keys of the keypad 13 corresponding to "1" are displayed in combination.

Thereafter, when all of the recipient numbers are input, the screen is roll-played and displayed as ... → 7 → 0 → 1 → 0 → 3 → 2 → 1 → 4 → 5 → 6 → 7 → 0 → 1 → 0 →. .

As described above, display of the incoming / outgoing signal on the keypad according to the present invention can be performed by controlling the inside of the mobile phone.
