Abstract

A cellular phone has a black-and-white LCD that displays characters and communication information and a color LCD that displays an image. The image and the characters are displayed on the separate LCDs. Thus, the characters are not superimposed on the image, and they are easy to see. When the image is not needed (the user is not using the phone or the user is talking on the phone), only the black-and-white LCD displays the characters and the color LCD is turned off to save energy.

Claims

1. A portable communication terminal, comprising:

a communicating device that transmits and receives image data and character data;

a storage device that stores image data and character data received by the communicating device;

an image displaying device and a character displaying device that display an image and characters according to the image data and the character data stored in the storage device, respectively; and

a display control device that controls the displays of the image displaying device and the character displaying device.

2. The portable communication terminal as set forth in

claim 1

, further comprising an imaging device;

wherein the display control device makes the image displaying device display the image according to the image data stored in the storage device or display an image captured by the imaging device.

3. The portable communication terminal as set forth in

claim 1

, further comprising a character inputting device;

wherein the display control device makes the image displaying device display the characters according to the character data or display characters inputted by the character inputting device.

4. The portable communication terminal as set forth in

claim 1

, wherein the image displaying device is color and the character displaying device is black-and-white.
