Description

Terminal recognition method based on contact recognition and terminal applied thereto {METHOD FOR MANAGING TOUCH RECOGNITION-BASED TERMINAL, AND TERMINAL APPLIED TO THE SAME}

The present invention relates to a terminal having a touch screen, and more particularly, when performing a display function and a control input function of a user through a screen of a terminal having a touch screen, a body part such as a user's hand and the like; The present invention relates to a function for switching the display of a terminal screen through contact recognition between external housings of a terminal and a touch recognition-based terminal manipulation method for controlling whether a user inputs a control to a terminal and a terminal applied thereto.

In modern times, as the spread of mobile terminals spreads and their functions are improved, mobile terminals have been developed to provide various multimedia functions by mounting various applications as well as existing voice call functions.

As such, as the multimedia functions are integrated into the mobile terminal, an increase in the amount of information to be processed requires an enlargement of the display device of the mobile terminal, and the liquid crystal display of the mobile terminal, particularly the clamshell mobile terminal, is limited by the size of the mobile terminal. It developed in a long form in the vertical direction rather than the direction.

The PCB is located inside the case of the mobile terminal. On the upper surface of the PCB, key terminals are installed as many as the number of buttons on the pad. And the dome switch part is mounted on the upper surface of the PCB. On the bottom of the dome switch part, a dome-shaped metal dome is attached to a point corresponding to the key terminal of the PCB, and the upper surface of the dome switch part is positioned so that the metal dome is positioned corresponding to the key terminal. Covering.

And the upper surface of the dome switch unit, the pad is installed at a point corresponding to the metal dome of the dome switch unit, the pad is generally composed of a flexible synthetic resin material.

The dome switch unit with the metal dome disposed as described above is disposed in the case of the mobile terminal in a state where the PCB is stacked.

Therefore, when the user presses any button of the keypad, the center portion is recessed by the button and connected to the lower key terminal. As the key terminal is connected, an electrical signal corresponding to the button pressed by the user is input. When the user removes the force, the metal dome is elastically restored and the key terminal is dropped.

In general, a keypad having such a structure is provided in a mobile terminal. However, in recent years, as the size of the keypad is limited due to the portability of the mobile terminal, a touch screen is used to efficiently perform a user's control input while further expanding the terminal screen. Equipped mobile terminals are on the trend.

In the touch screen terminal, when a user presses a specific point on the touch screen using a finger or a predetermined input tool, an output signal corresponding to the point is generated, and the linked information is displayed on the terminal screen. The desired information can be obtained.

However, the touch screen terminal merges a display function and a function for partially executing a user's control input through the touch screen as described above, and the user can carry the touch screen terminal while implementing the merged function. In order to prevent a malfunction such as control input with a touch screen, the hold switch provided in the terminal is adjusted to switch to a hold mode state to prevent a user's control input.

Accordingly, the user's point of view was the inconvenience of having to adjust the hold switch separately by executing control input through the touch screen or by not executing it. In order to execute the switching function, the terminal itself may be rotated through a physical method or an input of a specific button, and thus the hand movement may be an obstacle to the use of the terminal for the disabled or the elderly.

Due to these problems, there is a need for a solution to solve this problem.
