Mobile communication terminal with hot checking style key area

Abstract

The present invention relates to a mobile communication terminal with an improved key input section, which is characterized in that it includes: a keypad, which includes a thermal detection member separated in a lattice shape and a keyboard mapping member located on its upper part, and the keypad is detected by a thermal detection signal. The key input command is output; the storage unit is used to store the keyboard mapping data of the control command corresponding to each key input command; the heat detection signal processing unit reads out each heat from the keyboard mapping data when the heat is detected from the key input command. The control command corresponding to the detected key is output; for the mobile communication terminal with the keypad part of the user input command, a data input and output part is provided, which is used to update the keyboard mapping number in the storage part, and is used for input and output data at the same time. . When the keypad in the mobile communication terminal needs to be changed, the form of the keyboard can be changed by updating the keyboard mapping data, which is very convenient to use.

Description

technical field [0001] The present invention relates to a mobile communication terminal with an improved key input section, more specifically, a mobile communication terminal having a thermal detection type keypad section in which a key value can be input through a thermal detection operation. keypad. Background technique [0002] figure 1 It is a drawing of a mobile communication terminal body with a keyboard 20 in the prior art; figure 2 is for illustration figure 1 A simple structural block diagram of the mobile communication terminal in which the key input corresponds to the control command output action in the mobile communication terminal. [0003] As mentioned above, in the keypad 11 of the prior art mobile communication terminal, the inside of the upper shell 30 (case) of the body 10 is provided with a PCB type circuit board (not shown) for generating key input signals. A rubber plate-type keyboard 20 composed of a plurality of keys protruding upward for key inp...

Problems solved by technology

[0004] However, in the above-mentioned mobile communication terminal of the prior art, the keypad part has a fixed keyboard mapping according to the design of the keypad, so that it is necessary to redesign the keypad part when changing the keyboard mapping, so the above-mentioned change operation is relatively difficult.
