Abstract

A presentation device. The presentation device includes a display panel, a touch panel, and an image projector. The display panel having a display region displays presentation data. The touch panel obtains a coordinate from touch screen input. The image projector projects an indicating point according to the coordinates of the input region and the presentation data to a corresponding region on a screen.

Claims

1. A data processing device, comprising:

a touch panel for obtaining a coordinate from touch screen input; and

a display panel having a display region for displaying a predetermined data and an indicating point on the display region according to the coordinates of the input region.

2. The data processing device as claimed in claim 1, wherein the display panel is a liquid crystal display panel.

3. The data processing device as claimed in claim 1, further comprising a function key for enabling function of the indicating point.

4. A presentation device, comprising:

a display panel having a display region for displaying presentation data;

a touch panel for obtaining a coordinate from touch screen input; and

an image projector for projecting an indicating point according to the coordinates of the input region and the presentation data to a corresponding region on a screen.

5. The presentation device as claimed in claim 4, wherein the display panel is a liquid crystal display panel.

6. The presentation device as claimed in claim 4, further comprising a function key for enabling function of the indicating point.

7. A projection method of a presentation using a display panel and a touch panel, the method comprising the following steps:

projecting presentation data shown on the display panel onto a screen;

obtaining a coordinate of an input region detected by the touch panel; and

displaying an indicating point according to the coordinates of the input region.
