Description

Mobile phone with touch screen {PORTABLE RADIOTELEPHONE WITH TOUCH SCREEN}

The present invention relates to a mobile phone, and more particularly, to a mobile phone having a touch screen for inputting data such as letters and numbers by a touch operation.

Typically, a portable terminal refers to a portable device such as a handheld phone (HHP), a PCS phone, a digital phone, a cellular phone, or the like. The portable terminal mainly uses voice transmission through a link of a terminal, a base station, a mobile switching center, and a public telephone network.

At present, such portable terminals are being followed by the trend of miniaturization and light weight of electronic components, and bar-type, flip-type, and folder-type mobile phones coexist.

Among these mobile phones, flip type or folder type mobile phones with excellent sound sensitivity are becoming more common. The reason why flip-type cell phones and folder-type cell phones are common is to protect a plurality of keys to prevent malfunction of the keys and to collect sound by performing the role of a sound reflector during a call. Moreover, the flip type or folder type mobile phone is advantageous for miniaturization of the main body.

Currently, mobile phones are becoming smaller, but there is a limit to miniaturization in order to secure the distance between the user's ear and the mouth. That is, in the case of a portable terminal, the distance between the talker (part where the microphone device is located) and the receiver (part where the speaker device is located) should be 14 cm or more. Therefore, in a flip type mobile phone, a microphone device is installed in a flip, and in a folder type mobile phone, an attempt is made to maintain a communication distance by installing an LCD module or a speaker in a folder.

A typical bar type mobile phone has an antenna device installed at the top edge of a housing, an ear piece including a speaker under the antenna device, and an LCD module for displaying various information under the ear piece. In addition, the keypad as a data input device is disposed below the CD module, and the microphone device is installed below the keypad.

A typical flip type mobile phone is composed of a main body, a flip cover, and a hinge device for mechanically connecting the main body and the flip cover. An antenna device is located at the top edge of the main body, and an ear piece is located below the antenna device, The LCD module is located, the keypad is located under the LCD module, and the microphone device is located under the keypad. The flip cover rotates about the hinge axis in the main body.

A folder type mobile phone is composed of a main body, a folder, and a hinge device that mechanically connects the main body and a folder to open and close the call angle. In this case, the LCD module displaying various information may be mounted on a main body or a folder.

However, due to the development of technology that enables high-speed data transmission and increased user's desire to receive not only voice but also text services, hardware is required to implement data transmission services including text transmission in existing terminals. .

You can enter text using the keypad of current portable terminals. However, it is quite inconvenient to enter a sentence.

For example, if you input English "OEM" by pressing a finger, press key "6" to indicate "O", "M" is displayed on LCD, press volume key to find "O" You need to find and type "E" and "M" again. In the case of a simple name or place name is abbreviated, this inconvenience is somewhat resolved, but if you need to text services, it is very inconvenient to enter a sentence in this way. In addition, Hangeul is composed of initial, neutral, and final characters, which makes it more difficult to enter characters.

Due to this conventional problem, it is necessary to manufacture a terminal equipped with an input device capable of receiving text and numeric data and software capable of recognizing and processing the input data.

However, as an input device for inputting letters and numbers in a conventional mobile phone, if the touch screen is additionally occupied by a separate space, the size of the terminal will be increased. A detailed discussion of the matter is needed. That is, a new letter and number input method should be implemented while minimizing the increase in the volume of the mobile phone body.

In addition, since the attached touch screen is easily damaged due to the material, there is a need for protection and the need for easy repair due to damage has emerged.

The present invention has been made to solve the above-mentioned problems, an object of the present invention is to provide a mobile phone configured with a touch screen by mounting a touch sensitive panel on the LCD module.

Another object of the present invention is to provide a mobile phone with a means for protecting in consideration of the damage of the touch sensitive panel mounted on the LCD module.

Still another object of the present invention is to provide a mobile phone, which is advantageous in miniaturization, in which there is no functional deterioration and does not affect size increase even when the touch sensitive panel is attached on the LCD module.

Another object of the present invention is to provide a mobile phone easy to input letters or numbers due to the touch sensitive panel attached.

Another object of the present invention is to provide a mobile phone easy to maintain the attached touch sensitive panel.

In order to achieve the above objects, the present invention provides a flip type mobile phone comprising a main body (a), a flip cover (b), and a hinge device (c) for mechanically connecting the main body (a) and the flip cover (b). ,
