And a multimedia service processor and other switching unit, a microphone, a speaker, and the like, for outputting and outputting the voice data through the modulator.

Therefore, how to arrange the various components in a small wireless terminal to manufacture a compact wireless terminal, there is a problem how to overcome the electromagnetic interference problem caused by the integration of a large number of devices in the small terminal.

Conventionally, in the arrangement of such components, it is a general configuration method that the display device module includes only a display portion, a display portion driver portion, or a part or all of the image processing portion, and all the remaining portions are accumulated near the terminal body, that is, the key input portion.

However, in the case of such a configuration method, by placing the multimedia service processor in a limited space, the distance of each chip is too close, causing enormous disruption to their electromagnetic characteristics due to electromagnetic interference, etc., as the space becomes narrower. There is a problem that there is not enough space to install the chips required to provide new functions required in the future.

In particular, in the case of a folding type wireless cellular phone, even though the entire terminal is divided into upper and lower parts, only the display unit is located at the upper part and many devices except the lower part are located, so that the spatial distribution of the device is not balanced. There is this.

In order to solve the problems of the prior art as described above, the present invention provides a display device module for a wireless terminal including a multimedia service processing unit that can prevent the devices are concentrated in a narrow space in a small wireless terminal causing electromagnetic interference. For the purpose of

In addition, an object of the present invention is to provide a display device module for a wireless terminal including a multimedia service processing unit for securing a space for additionally installing a device required for various services to be made through the wireless terminal in the future.
