ACTIVE MATRIX DISPLAY DEVICES AND PORTABLE ELECTRONIC PRODUCTS USING THE SAME

1 . An active matrix display device, comprising:

a display area, having a plurality of pixels arranged in rows and columns;

at least one source driving device, providing power or electric charges for the pixels through source lines, wherein the number of source lines is equal to the number of columns;

at least one gate driving device, controlling on/off of the pixels through gate lines, wherein the number of gate lines is equal to the number of rows; and

a boundary switch, separating the display area into a plurality of sub-display areas and placed between the sub-display areas to connect or disconnect the source lines and/or the gate lines,

wherein when the boundary switch disconnects the source lines and/or the gate lines, the sub-display areas directly connecting with the source driving device and the gate driving device are driven.

2 . The active matrix display device of claim 1 , wherein:

the source driving device and the gate driving device are arranged one separately; and

the boundary switch separates the display area into a first sub-display area and a second sub-display area and is configured between the two sub-display areas to connect or disconnect the source lines, wherein the first sub-display area and second sub-display area are disposed at the upper and lower side of the boundary switch, respectively,

wherein when the boundary switch disconnects the boundary switch disconnects the source lines, the sub-display area which is not directly connecting with the source driving device is not driven.

3 . The active matrix display device of claim 2 , further comprising:

a second source driving device, configured at the other side of the display area opposite to the source driving device,

wherein the gate driving device has two sub-driving areas connected or disconnected by the boundary switch, and

when the boundary switch disconnects the source lines, the sub-display area which is not directly connecting with the source driving device is driven by the second source driving device and one of the sub-driving areas directly connecting this sub-display area.

4 . The active matrix display device of claim 1 , wherein:

the source driving device and the gate driving device are arranged one separately; and

the boundary switch separates the display area into a first sub-display area and second sub-display area and is configured between the two sub-display areas to connect or disconnect the gate lines, wherein the first sub-display area and second sub-display area are disposed at the left and right side of the boundary switch, respectively,

wherein when the boundary switch disconnects the gate lines, the sub-display area which is not directly connecting with the gate driving device is not driven.

5 . The active matrix display device of claim 4 , further comprising:

a second gate driving device, configured at the other side of the display area opposite to the gate driving device,

wherein when the boundary switch disconnects the gate lines, the sub-display area which is not directly connecting with the gate driving device is driven by the second gate driving device.

6 . The active matrix display device of claim 1 , wherein:

the boundary switch has a plurality of switch elements;

the switch elements are arranged in a line and inserted into the source lines or the gate lines of the sub-display areas; and

the control terminals of the switch elements all connect to a switch driving device and the switch elements do on/off controls through control signals provided by the switch driving device at the same time.

7 . The active matrix display device of claim 6 , wherein each of the switch elements has at least one of an n-channel TFT, a p-channel TFT, and a transmission gate.

8 . The active matrix display device of claim 1 , wherein:

the boundary switch has a plurality of demultiplexers when there are different pixels between the sub-display areas;

the demultiplexers have switch elements of which the number of switch elements corresponds to the ratio of the number of pixels between the sub-display areas;

the demultiplexers are arranged in a line and inserted into the source lines or the gate lines between the sub-display areas; and

the control terminals of the switch elements all connect to a switch driving device and the switch elements do on/off controls at the same time through control signals provided by the switch driving device.

9 . The active matrix display device of claim 1 , wherein:

the sub-display area separated from the source driving device or the gate driving device has a plurality of pixels with memories, and

the memories store the statuses of the pixels of when the boundary switch disconnects the source lines and/or the gate lines.

10 . The active matrix display device of claim 1 , wherein the active matrix display device is a liquid crystal display device.

11 . The active matrix display device of claim 1 , wherein the active matrix display device is an organic light-emitting diode display device.

12 . A portable electronic product, comprising the active matrix display device of claim 1 .
