Abstract

A driving circuit according to an embodiment of the present invention includes an input terminal, unit circuits connected to the input terminal, and output terminals electrically connected to the input terminals. Each of the unit circuits is enabled in response to a control signal inputted via the input terminal.

Claims (14)

1. A driving circuit comprising:

an input terminal;

unit circuits connected to the input terminal; and

output terminals electrically connected to the input terminal,

wherein each of the unit circuits comprises a plurality of output pins and a selected number of the output pins of the unit circuits is enabled in response to a control signal inputted via the input terminal and the control signal is a signal having two bits,

wherein the number of the output pins is larger than the number of gate lines of a display devise connected to the driving circuit.

2. The driving circuit of claim 1 , wherein the driving circuit is a gate driving integrated circuit.

3. The driving circuit of claim 2 , wherein the gate driving integrated circuit comprises 400 output pins.

4. The driving circuit of claim 3 , wherein the selected number of enabled output pins is one of 342, 350, 384 and 400.

5. The driving circuit of claim 1 , wherein the gate driving integrated circuit comprises 642 output pins, and a selected number of output pins are enabled in response to the control signal.

6. The driving circuit of claim 5 , wherein the selected number of enabled output pins is one of 600, 618, 630 and 642.

7. The driving circuit of claim 1 , wherein each of the unit circuits comprises a portion having a shift register, a latch, a digital to analogue converter and an output buffer.

8. A driving circuit comprising: unit circuits including a plurality of output pins, wherein a part of output pins are used and the other part of output pins are not used and the number of the output pins is larger than the number of gate lines of a display device connected to the driving circuit.

9. The driving circuit of claim 8 , further comprising output terminals, wherein the output pins of the unit circuit are electrically connected to the output terminals.
