Abstract

An apparatus and method for displaying a multimedia screen in a mobile terminal. A first memory selectively stores multimedia image data received at a service request of the mobile terminal or text data and background screen image data provided for a display service of the mobile terminal. A second memory stores the text data and the background screen image data. An image output processor reads data from the first memory and the second memory, and provides the read data to a display unit of the mobile terminal.

Claims

1. A screen display apparatus in a mobile terminal, comprising:

a first memory for selectively storing multimedia image data received at a service request of the mobile terminal or text data and background screen image data provided for a display service of the mobile terminal;

a second memory for storing the text data and the background screen image data; and

an image output processor for reading data from the first memory and the second memory, and for providing the read data to a display unit.

2. A screen display apparatus in a mobile terminal, comprising:

a first memory for storing data of a first resolution;

a second memory for storing data of a second resolution lower than the first resolution;

a first selector for selectively providing, in response to a first control signal, the first memory with image data received at a service request of the mobile terminal or text data and background screen image data provided for a display service of the mobile terminal;

a second selector for selectively providing the text data and the background screen image data to the first selector or the second memory in response to a second control signal; and

an image output processor for reading data from the first memory and the second memory, and for providing the read data to a display unit of the mobile terminal.

3. A screen display method in a mobile terminal including a first memory for outputting data of a first resolution and a second memory for outputting data of a second resolution lower than the first resolution, comprising:

selectively storing, in the first memory, multimedia image data received at a service request of the mobile terminal or text data and background screen image data provided for a display service of the mobile terminal;

storing the text data and the background screen image data in the second memory; and

reading data from the first memory and the second memory, and displaying the read data on a display unit of the mobile terminal.

4. The screen display method as claimed in claim 3, wherein the first resolution is substantially equivalent to a level of a real color.
