Problems solved by technology
[0007] But the problem that exists in the above prior art is that when the user slowly closes the flip of the flip-type mobile communication terminal 72, even if the user cannot see the LCD screen from the angle of view, since the magnet detection type element 71 is not implemented at this time, Magnetization, from a certain angle until the cover is fully closed, can only continue to supply unnecessary power to the LCD screen
[0008] On the contrary, when the user flips up the flip cover, below a certain angle, although the LCD screen has not yet entered the range of the user's viewing angle, the moment the flip cover is opened, the magnet detection element 71 immediately detects that the flip cover is opened, thereby passing Supplying power for the LCD screen early increases the energy consumption of the battery

The invention provides a mobile communication terminal with menu-control function. The terminal comprises: hinge part provided with circular variable resistor and two contacts in the hinge rotating part for outputting corresponding voltage value based on the distance between two contacts; AD converter converting the analog signal outputted from the variable resistor in the hinge part to the digital signal and supporting to the mobile station modem; mobile station modem controlling the on-off of the LCD menu based on the changable voltage value due to the hinge part rotation and controlling the calling connection state; LCD display part turning on / off the menu based on the MSM display control signal. The hinge part of the flip-type mobile communication terminal has two contacts and variable resistor and gets a more effectively controlled LCD menu effect using the changable voltage value followed by the hinge part rotation.
Description
technical field [0001] The present invention relates to an additional function of a mobile communication terminal, more specifically, to a flip-type mobile communication terminal with two contacts and a variable resistor on the hinge, using the voltage value change generated when the hinge is rotated, A mobile communication terminal with a screen control function that can control an LCD screen more effectively. Background technique [0002] Recently, with the rapid development of communication technology, mobile communication systems that allow individuals to communicate with others at any place or while moving from one place to another are being developed and applied. [0003] The mobile communication terminal used in the above-mentioned mobile communication system has gone beyond the existing simple call function, and has added various additional service functions, and according to the different preferences of different users, it has changed from the original bar type mobi...
