Problems solved by technology

However, the size of the keys is an obstacle to terminal miniaturization
Although the keys of the keyboard should be correspondingly reduced in size to miniaturize the terminal, too small keys cause inconvenience for users to press the keys
On the other hand, although the enlarged keys will make data input convenient, it will increase the size of the terminal body.
Furthermore, conventional terminals suffer from electrostatic discharge (ESD) problems when static electricity is introduced through key insertion holes in the frame

Abstract

Disclosed are a wide keypad and a wide keypad mounting structure in a portable terminal. In the wide keypad, a plurality of key tops are arranged in tight contact in a matrix of rows and columns. A key film has a plurality of upper protrusions in contact with the bottom surfaces of the key tops, a plurality of lower protrusions as contact points spaced from metal domes, and recesses between the upper protrusions. A key frame is inserted into the recesses of the key film and has at least one spacer extended upward for providing space in which the key tops move up and down between the upper casing frame and the key film.

Description

technical field [0001] The present invention generally relates to a keyboard for inputting information including letters and numbers in a terminal, and in particular to a wide keyboard and a wide keyboard support structure. This wide keyboard and its support structure increase the contact area for convenient pressing of keys and enable Static electricity on the keyboard is minimized. Background technique [0002] A portable terminal is a mobile station that provides radio communication services to users through radio contact with a base station. In addition to transmitting sound and pictures, the terminal can also provide radio communication services such as e-mail or Internet chat. Generally, terminals are classified into a strip type, a clamshell type, and a folder type according to the appearance. Typically a terminal includes a data entry device, a liquid crystal display (LCD) to display incoming data, a voice transmitter / receiver, and an antenna assembly. Figure 1 sh...
