T2 is all not turned on switch element T3.Reset voltage Vrst is high-voltage level, therefore switch element T4 is not turned on, and node Q is
Low voltage level so that switch element T5 turns on switch element T6.Operating voltage VDD is provided to node by switch element T5
BT, therefore node BT is high-voltage level.Node BT is high-voltage level, therefore switch element T1 is not turned on.Operating voltage VDD
There is provided by switch element T6 to output end OUT, therefore output end OUT is high-voltage level.Signal shade unit 120 will not
Pulse signal CLK one of is exported to multi-strip scanning line G1~GN.Therefore, pulse signal CLK is low when period P12
Voltage level, because signal shade unit 120 one of does not export pulse signal CLK to multi-strip scanning line G1~GN,
It is high-voltage level now to scan line voltage G [n], therefore one of multi-strip scanning line G1~GN does not update and multi-strip scanning
The active area 130 that one of line G1~GN is mutually coupled.
Refer to Figure 18.Figure 18 is a kind of stream of signal shade method 600 according to depicted in some embodiments of this case
Cheng Tu.As shown in figure 18, signal shade method 600 comprises the steps of：
Step S610：Drive circuit is set to receive the first control signal and the second control signal according to drive signal；
Step S620：Make drive circuit return pulse signal；
Step S630：When the first control signal is in first voltage level and the second control signal is in second voltage level
When, make drive circuit output pulse signal；
Step S640：When the first control signal is in second voltage level and the second control signal is in first voltage level
When, drive circuit is stopped output pulse signal；And
Step S650：Drive circuit is set selectively to receive reset voltage according to reset voltage and the first control signal, wherein
Reset voltage has second voltage level, and reset voltage makes drive circuit stop output pulse signal.
To make the signal shade method 600 of this case embodiment it can be readily appreciated that also referring to Fig. 3~Figure 18.
In step S610, drive circuit is set to receive the first control signal and the second control signal according to drive signal.
In some embodiments, drive circuit can be the signal shade unit 120 shown as depicted in fig. 3.For example, in some embodiments
In, when drive signal En is low voltage level, switch element T2 turns on switch element T3, then signal shade unit 120 connects
Receive control signal Vin_1 and control signal Vin_2.
In step S620, make drive circuit return pulse signal.In certain embodiments, and pulse signal CLK be by
The switch element T1 of signal shade unit 120 is received.
In step S630, when the first control signal is in first voltage level and the second control signal is in second voltage
During level, make drive circuit output pulse signal.For example, show as depicted in fig. 7, now control signal Vin_1 is in high electricity
Voltage level, control signal Vin_2 are in low voltage level.Node Q is high-voltage level, therefore switch element T5 and switch element
T6 is not turned on.Node BT is low voltage level, and switch element T1 is turned on.Signal shade unit 120 by pulse signal CLK export to
One of multi-strip scanning line G1~GN.Now, pulse signal CLK is low voltage level, therefore in multi-strip scanning line G1~GN
One of the active area 130 that mutually couples of one of renewal and multi-strip scanning line G1~GN.
In step S640, when the first control signal is in second voltage level and the second control signal is in first voltage
During level, drive circuit is set to stop output pulse signal.For example, as depicted in Figure 12 to Figure 17, in Figure 12 to Figure 17,
Control signal Vin_1 is in low voltage level, and control signal Vin_2 is in high-voltage level, and switch element T1 is all not turned on,
Therefore signal shade unit 120 one of does not export pulse signal CLK to multi-strip scanning line G1~GN.
In step S650, drive circuit is set selectively to receive reset voltage according to reset voltage and the first control signal,
Wherein reset voltage has second voltage level, and reset voltage makes drive circuit stop output pulse signal.For example, please
Refering to Fig. 8, when reset voltage Vrst is low voltage level, switch element T4 conductings, now node Q is low voltage level, and
Turn on switch element T5 and switch element T6.Now node BT is high-voltage level, and switch element T1 is not turned on, therefore signal
Shade unit 120 one of does not export pulse signal CLK to multi-strip scanning line G1~GN.
In certain embodiments, drive signal En is as produced by the signal generator 110 as depicted in Fig. 1 and inputted extremely
Signal shade unit 120.In some other embodiment, drive signal En is hidden by the previous stage signal in display panel 100
Produced by cover unit 120 and input to the signal shade unit 120 for working as level.
In certain embodiments, the reset voltage Vrst depicted in Fig. 4 and Figure 11 and pulse signal CLK changes for periodicity
Become.
As shown in Fig. 4~Figure 17, when control signal Vin_1 is in high-voltage level, and control signal Vin_2 is in low electricity
One of during voltage level, signal shade unit 120 exports pulse signal CLK to multi-strip scanning line G1~GN.And if pulse
Signal CLK is low voltage level, and scanning line voltage G [n] is low voltage level, therefore one of multi-strip scanning line G1~GN is more
The active area 130 newly mutually coupled with one of multi-strip scanning line G1~GN.On the other hand, when control signal Vin_1 is in
Low voltage level, and when control signal Vin_2 is in high-voltage level, signal shade unit 120 all will not be by pulse signal CLK
Output is one of to multi-strip scanning line G1~GN, therefore one of multi-strip scanning line G1~GN will not update and multi-strip scanning
The active area 130 that one of line G1~GN is mutually coupled.By the above-mentioned means, the embodiment of this case can be by controlling control letter
Number Vin_1 and control signal Vin_2, display panel 100 is set only to need to update the part active area 130 that needs update, with reduction
The power consumption of display panel 100.
From the embodiment of above-mentioned this case, the embodiment of this case is by providing a kind of signal shade unit, Yi Zhongxin
Number shade method and a kind of display panel, and more particularly to signal shade unit, signal shade method and the display surface of low-power consumption
Plate, use the power consumption for effectively while the efficiency of display device is not reduced, reducing display device.
