Abstract

A dual screen point-of-sale system includes a point-of-sale device and a tablet computer. The point-of-sale device includes a first display screen and a first connection part. A first picture of the point-of-sale device is shown on the first display screen in response to a first device signal. The first connection part receives the first device signal. The tablet computer includes a second connection part and a second display screen. When the first connection part and the first connection part are in communication with each other, the first device signal is transmitted from the point-of-sale device to the tablet computer. Consequently, a picture corresponding to the first device signal is shown on the second display screen. When the first connection part and the first connection part are not in communication with each other, a second picture is shown on the second display screen.

First claim

What is claimed is:

1. A dual screen point-of-sale system, comprising:
a point-of-sale device comprising:
a first display screen, displaying a first picture of the point-of-sale device in response to a first device signal, wherein the first device signal contains a first picture signal corresponding to the first picture and an extended picture signal corresponding to an extended picture;
a first connection part, receiving the first device signal;
a connection interface; and
a first converter, electrically connected with the connection interface and the first connection part, wherein when the first picture signal or the extended picture signal is transferred through the connection interface to be received and converted into a serialized signal by the first converter, and the serialized signal is transmitted to the first connection part; and

a tablet computer, detachably assembled with the point-of-sale device, comprising:
a second display screen, displaying a second picture of the tablet computer or a picture corresponding to the first device signal;
a second connection part wherein when the first connection part and the second connection part are in communication with each other, the serialized signal is transmitted from the point-of-sale device to the tablet computer through the first connection part and the second connection part, so that the picture corresponding to the first device signal is shown on the second display screen, wherein when the first connection part and the second connection part are not in communication with each other, the second picture is shown on the second display screen;
a second converter, electrically connected with the second connection part, wherein when the serialized signal is received by the second converter through the first connection part and the second connection part, and the serialized signal is converted into the first picture signal or the extended picture signal by the second converter;
a controlling unit, issuing a second picture signal corresponding to the second picture; and
a switch element, electrically connected with the second converter, the controlling unit and the second display screen, wherein the first device signal or the second picture signal is selectively transmitted to the second display screen through the switch element, so that the picture corresponding to the first device signal or the second picture is shown on the second display screen, wherein:
when the first picture signal of the first device signal is received by the switch element and the first picture signal is transmitted to the second display screen through the switch element, the first picture is shown on the second display screen in response to the first picture signal,
when the extended picture signal of the first device signal is received by the switch element and the extended picture signal is transmitted to the second display screen through the switch element, the extended picture is shown on the second display screen in response to the extended picture signal, and
when the second picture signal is received by the switch element and the second picture signal is transmitted to the second display screen through the switch element, the second picture signal is shown on the second display screen in response to the second picture signal.

2. The dual screen point-of-sale system according to claim 1 , wherein the first converter is a serializer.

3. The dual screen point-of-sale system according to claim 1 , wherein a number of electrically-connected pins of the connection interface is larger than a number of electrically-connected pins of the first connection part.

4. The dual screen point-of-sale system according to claim 1 , wherein the first picture, the second picture or the extended picture is shown on the second display screen in a full screen mode.

5. The dual screen point-of-sale system according to claim 1 , wherein the second converter is a deserializer.

6. A dual screen point-of-sale system, comprising:
a point-of-sale device, comprising:
a first display screen displaying a first picture of the point-of-sale device in response to a first device signal, wherein the first device signal contains a first picture signal corresponding to the first picture and an extended picture signal corresponding to an extended picture;
a first connection part receiving the first device signal;
a connection interface; and
a first converter electrically connected with the connection interface and the first connection part, wherein when the first picture signal or the extended picture signal is transferred through the connection interface to be received and converted into a serialized signal by the first converter, the serialized signal is transmitted to the first connection part; and

a tablet computer detachably assembled with the point-of-sale device, comprising:
a second display screen displaying a second picture of the tablet computer or a picture corresponding to the first device signal;
a second connection part, wherein when the first connection part and the second connection part are in communication with each other, the serialized signal is transmitted from the point-of-sale device to the tablet computer through the first connection part and the second connection part, so that the picture corresponding to the first device signal is shown on the second display screen, wherein when the first connection part and the second connection part are not in communication with each other, the second picture is shown on the second display screen;
a second converter electrically connected with the second connection part, wherein when the serialized signal is received by the second converter through the first connection part and the second connection part, the serialized signal is converted into the first device signal by the second converter;
a camera module providing a camera signal corresponding to a camera-captured picture;
a switch element electrically connected with the second converter and the camera module, wherein the switch element receives the first device signal and the camera signal and selectively outputs the first device signal or the camera signal; and
a controlling module electrically connected with the second converter, the second display screen and the switch element, wherein a second picture signal corresponding to the second picture is outputted from the controlling module to the second display screen, or the camera-captured picture is shown on the second display screen under control of the controlling module, wherein if the controlling module judges that the first connection part and the second connection are not in communication with each other, the second picture is shown on the second display screen under control of the controlling module, wherein if the controlling module judges that the first connection part and the second connection are in communication with each other, the picture corresponding to the first device signal is shown on the second display screen under control of the controlling module.

7. The dual screen point-of-sale system according to claim 6 , wherein the controlling module comprises:
a detecting element electrically connected with the second converter, and judging whether the first connection part and the second connection are in communication with each other, wherein if the detecting element judges that the first connection part and the second connection are in communication with each other, the detecting element issues an enabling signal, wherein if the detecting element judges that the first connection part and the second connection are not in communication with each other, the detecting element issues a disabling signal; and
a controlling unit electrically connected with the switch element, the secon
