Abstract

A non-volatile display module has a display panel and a driving circuit. The display panel has a substrate at which at least one scan line, at least one data line and at least one thin film transistor (TFT) are disposed. The TFT is located at an intersection area of the scan line and data line. The driving circuit has a driving unit, a power converting unit and a multiplexing unit. The driving unit receives at least one image controlling signal according to a clock signal. The power converting unit generates a plurality of power signals. The multiplexing unit is electrically connected with the scan line, the data line, the driving unit and the power converting unit, and outputs one of the power signals to the scan line or the data line according to the image controlling signal. A non-volatile display apparatus is also disclosed.

Claims (31)

1. A non-volatile display module, comprising:

a display panel having a substrate, wherein at least one scan line, at least one data line and at least one thin film transistor (TFT) are disposed on the substrate, and the TFT is disposed at an intersection area of the scan line and the data line; and

an integrated driving circuit having:

only a driving unit receiving at least an image controlling signal according to only a clock signal, wherein the image controlling signal has a plurality of first driving signals and a plurality of second driving signals;

a power converting unit generating a plurality of power signals; and

a multiplexing unit directly connected with the scan line, the data line, the driving unit and the power converting unit, respectively;

wherein the multiplexer transmits one of the power signals to the scan line according to one of the first driving signals to determine a voltage level of a scan signal transmitted by the scan line, and the multiplexer transmits one of the power signals to the data line according to one of the second driving signals to determine a voltage level of an image signal transmitted by the data line.

2. The display module as recited in claim 1 , wherein the driving unit has:

at least one shift register receiving the image controlling signal according to the clock signal; and

at least one latch electrically connected with the shift register and receiving the image controlling signal according to a latch signal.

3. The display module as recited in claim 1 , wherein the power converting unit is a DC/DC converting unit.

4. The display module as recited in claim 1 , wherein at least one portion of the display module is made through a mono-crystalline process, a multi-crystalline process or an amorphous process.

5. The display module as recited in claim 4 , wherein the amorphous process is an amorphous silicon TFT process or an organic TFT process.

6. The display module as recited in claim 1 , wherein the driving unit, the power converting unit and the multiplexing unit are configured in an integrated circuit (IC).

7. The display module as recited in claim 1 , wherein the driving unit and the multiplexing unit are configured in an integrated circuit (IC).

8. A non-volatile display apparatus, comprising:

a non-volatile display module, comprising:

a display panel having a substrate, wherein at least one scan line, at least one data line and at least one thin film transistor (TFT) are disposed on the substrate, and the TFT is disposed at an intersection area of the scan line and the data line; and

an integrated driving circuit having:

only a driving unit receiving at least an image controlling signal according to only a clock signal, wherein the image controlling signal has a plurality of first driving signals and a plurality of second driving signals;

a power converting unit generating a plurality of power signals; and

a multiplexing unit, directly connected with the scan line, the data line, the driving unit and the power converting unit, respectively;

wherein the multiplexer transmits one of the power signals to the scan line according to one of the first driving signals to determine a voltage level of a scan signal transmitted by the scan line, and the multiplexer transmits one of the power signals to the data line according to one of the second driving signals to determine a voltage level of an image signal transmitted by the data line.

9. The display apparatus as recited in claim 8 , wherein the driving unit has:

at least one shift register, receiving the image controlling signal according to the clock signal; and

at least one latch, electrically connected with the shift register and receiving the image controlling signal according to a latch signal.

10. The display apparatus as recited in claim 8 , wherein the power converting unit is a DC/DC converting unit.

11. The display apparatus as recited in claim 8 , wherein at least one portion of the display module is made by a mono-crystalline process, a multi-crystalline process or an amorphous process.

12. The display apparatus as recited in claim 11 , wherein the amorphous process is an amorphous silicon TFT process or an organic TFT process.

13. The display apparatus as recited in claim 8 , wherein the driving unit, the power converting unit and the multiplexing unit are configured in an integrated circuit (IC).

14. The display apparatus as recited in claim 8 , wherein the driving unit and the multiplexing unit are configured in an integrated circuit (IC).
