Display apparatus including a gate driving part having a transferring stage and an output stage and method for driving the same
View Patent ↗In a display apparatus and a method for driving the display apparatus, the display apparatus includes a display panel and a gate driving part. The display panel has a gate line, and a gate driving part has a plurality of stages and a plurality of signal lines. At least one of the stages includes a transferring stage sequentially driving the stage, and an output stage partially driving the gate line, in response to a signal outputted from the transferring stage and a driving area selection signal. Accordingly, the display apparatus is partially driven, so that current consumption may be decreased, the display apparatus may be more safely driven, and a position, a size and the number of a non-display area may be more easily controlled.
1. A display apparatus comprising:
a display panel having a plurality of gate lines; and
a gate driving part having a plurality of stages and a plurality of signal lines, the plurality of stages including:
a plurality of transferring stages that sequentially drive the plurality of stages; and
a plurality of output stages that sequentially output a gate signal to the gate lines in response to signals outputted from the transferring stages,
wherein clock pulses applied to the plurality of stages have substantially the same pulse duration during both the outputting of the gate signal to the at least one of the plurality of gate lines and the skipping of the outputting of the gate signal to a same one of the at least one of the plurality of gate lines, and
wherein at least one of the transferring stages applies a carry signal to one of next transferring stages to operate the one of next transferring stages, applies a delivery signal to a current output stage, and applies a first reset signal to one of previous transferring stages, and
wherein the current output stage is configured to selectively skip outputting the gate signal to at least one of the gate lines in response to the delivery signal and a driving area selection signal applied thereto.
2. The display apparatus of claim 1 , wherein a first period of the driving area selection signal includes a high-level period, and a second period of the driving area selection signal includes a low-level period.
3. The display apparatus of claim 2 , wherein at least one of the transferring stages comprises:
a first transferring pull-up driving control part that generates a first control signal;
a second transferring pull-up driving control part that generates a second control signal; and
a transferring pull-up driving part that generates an output signal including the carry signal, the delivery signal and the first reset signal in response to the first and second control signals.
4. The display apparatus of claim 2 , wherein at least one of the output stages comprises:
a first output pull-up driving control part that generates a third control signal;
a second output pull-up driving control part that generates a fourth control signal; and
an output pull-up driving part that generates an output signal in response to the third and fourth control signals.
5. The display apparatus of claim 4 , wherein the output signal comprises a gate signal.
6. The display apparatus of claim 5 , wherein the output signal further comprises a second reset signal.
7. The display apparatus of claim 6 , wherein the first output pull-up driving control part comprises:
a control terminal that receives an output signal of a transferring pull-up signal;
an input terminal that receives the driving area selection signal; and
an output terminal that outputs the third control signal.
8. The display apparatus of claim 2 , wherein the driving area selection signal has a first phase in an area corresponding to a display period, and has a second phase different from the first phase in an area corresponding to a non-display period.
9. The display apparatus of claim 8 , wherein the driving area selection signal has a high level in the area corresponding to the display period, and has a low level in the area corresponding to the non-display period.
10. The display apparatus of claim 2 , wherein at least one of the output stages comprises:
a first output pull-up driving control part that generates a third control signal;
a second output pull-up driving control part that generates a fourth control signal; and
an output pull-up driving part that generates a gate signal in response to the third and fourth control signal,
wherein the driving area selection signal has a high level in an area corresponding to a display period, and has a low level in an area corresponding to a non-display period, and the first output pull-up driving control part includes:
a control terminal that receives an output signal of a transferring pull-up driving part;
an input terminal that receives the driving area selection signal; and
an output terminal that outputs a third control signal.
