Data signal DATA；One electrical characteristic of data signal DATA stabilizing output circuit 50, in other words, number
The number of it is believed that DATA stablizes an electrical characteristic of learning type drive circuit 30.
Switching circuit 40 comprises multiple transistor M1, M2, and transistor M1 has an input, a control
End and an outfan, input couples data signal DATA, controls end and couples scanning signal VS, outfan
Coupling transistors M2, what the gate driver circuit that wherein scanning signal VS is display 10 was exported sweeps
Retouching signal VS, scanning signal VS is via multiple pixels of scan line scanning display 10.
Transistor M2 has an input, control end and an outfan, an input coupling transistors M1
Outfan, control end equally couple scanning signal VS, outfan couples output circuit 50 and a capacitor
First end of CST.Scan the signal VS control end controlling end and transistor M2 via transistor M1,
And control the transmission of data signal DATA.In other words, scanning signal VS control switching circuit 40 transmits number
The number of it is believed that DATA is to output circuit 50.
With reference to Fig. 1, output circuit 50 can be a transistor M3, transistor M3 have an input, one
Controlling end and an outfan, input couples one first signal VDD, controls end and couples in switching circuit 40
The outfan of transistor M2, second end of outfan coupling capacitor CST and the first end of luminescence component 20.
Transistor M3 produces according to data signal DATA and the first signal VDD and drives signal Ids to luminescence component
20.In other words, output circuit 50 receives data signal DATA and the first signal VDD, and data signal DATA
Control output circuit 50 and produce driving signal Ids to luminescence component 20 according to the first signal VDD.
Accepting above-mentioned, the first end of luminescence component 20 couples driving signal Ids, and the 1 of luminescence component 20 the
Two ends couple secondary signal VSS, and in other words, luminescence component 20 is coupled to drive signal Ids and second
Between signal VSS, and luminescence component 20 according to drive signal Ids produce light for display picture,
Wherein secondary signal VSS can be a reference power source.
Furthermore, sample circuit 60 can be a transistor M4, and transistor M4 has an input, a control
End processed and an outfan, input couples the outfan of output circuit 50 and the first end of luminescence component 20,
In other words, the input of transistor M4 is coupled to the of the outfan of output circuit 50 and luminescence component 20
Between one end.Furthermore, the control end of transistor M4 couples control signal VC, the output of transistor M4
End couples learning controller 70.Control signal VC controls transistor M4 and opens (conducting) and believe sampling
Number Ids2 samples, and wherein control signal VC can be produced by other circuit of display 10 with designed, designed
Raw, the present invention is not limiting as the source of control signal VC.
It is a current signal when driving signal Ids, and output circuit 50 produces when driving signal Ids, electricity
Stream can branch to luminescence component 20 and transistor M4, produces a shunting signal Ids1 respectively via after shunting
With sampled signal Ids2, shunting signal Ids1 is used for driven for emitting lights assembly 20, and sampled signal Ids2 is
The signal that sample circuit 60 to be sampled.Furthermore, shunting signal Ids1 is with sampled signal Ids2 between the two
Being the first proportionate relationship, this ratio can change via the design of transistor M4, and this is not compared by the present invention
Example makees a restriction.Therefore, sampled signal Ids2 that sample circuit 60 samples is relevant to drive signal Ids
With shunting signal Ids1.
In like manner, sampled signal Ids2 the most also has the second proportionate relationship with driving signal Ids.Institute
After repeating to receive sampled signal Ids2 so that, learning controller 70 couples the outfan of sample circuit 60,
The change driving signal Ids can be learnt according to the change of sampled signal Ids2, and drive signal Ids

Again seeing Fig. 1, in the time that display 10 shows picture, (time of display picture is in the present embodiment
Referred to as one display time) interior (period), output circuit 50 must produce driving signal Ids, and when defeated
Going out circuit 50 when being intended to produce driving signal Ids, the input of output circuit 50 receives one first signal VDD,
The control end of output circuit 50 receives data signal DATA, and the first signal VDD with data signal DATA is
One positive voltage (0N), and drive the level of signal Ids to believe less than data via the coupling of a capacitor CST

Signal Ids and secondary signal VSS, and drive the level of signal Ids need to be higher than the level of secondary signal VSS.
Otherwise, it is embodiment of the present invention learning formula drive circuit non-driven for emitting lights assembly refering to Fig. 2, Fig. 2
Produce principle schematic during light.As it can be seen, do not show that the time of picture (does not shows at display 10
Show that the time of picture is referred to as the non-display time in the present embodiment) in, output circuit 50 drives without output
During dynamic signal Ids, the first signal VDD can be 0 volt, and namely shunting signal Ids1 is 0 ampere,
And secondary signal VSS is similarly 0 volt, such luminescence component 20 will not produce light.Or, will
Shunting signal Ids1 and secondary signal VSS are set as that the level of shunting signal Ids1 is less than secondary signal VSS
Level, then luminescence component 20 will not produce light, by that analogy, the level of the first signal VDD equally
Less than the level of secondary signal VSS, then luminescence component 20 also will not produce light.
Additionally, when display 10 shows picture for a long time, transistor M3 (as shown in Figure 2) is long-time
It is in the duty of output drive signal Ids, the decay that the electrical characteristic of such transistor M3 can continue.
Because the electrical characteristic of transistor M3 can decay along with the working time, so driving the level meeting of signal Ids
Along with the working time of transistor M3 is the longest and the lowest.Furthermore, because of shunting signal Ids1 and sampled signal
Both Ids2 all become a proportionate relationship with driving signal Ids, so when the level driving signal Ids reduces
Time, the level of shunting signal Ids1 and sampled signal Ids2 is as well as reduction.In other words, transistor
The electrical characteristic of M3 can cause the level of shunting signal Ids1 and sampled signal Ids2 to be varied from, otherwise,
When the level of shunting signal Ids1 and sampled signal Ids2 reduces, the electrical characteristic representing transistor M3 declines
Subtract.
Accept above-mentioned, when the electrical characteristic of transistor M3 is when showing time decay, and the present invention is at display
The non-display time of 10 recovers the electrical characteristic of transistor M3, in an embodiment of the present invention, transistor M3
The time recovering electrical characteristic is referred to as a turnaround time.In other words, output circuit 50 has turnaround time,
And the electrical characteristic of output circuit 50 adjusted within turnaround time, and it is positioned at the non-of display 10 turnaround time
The display time.
Output circuit 50 of the present invention has the working time, and the working time comprises display time and turnaround time,
Within turnaround time, control the level of data signal DATA and make the electrical characteristic of output circuit 50 recover.As
Shown in Fig. 3, Fig. 3 is the sequential chart of embodiment of the present invention learning formula drive circuit, inventive display
10 turnaround time control scanning signal VS the level that level is high level and data signal DATA be one
Low level (negative voltage ,-Vdn), the control end (node A) of such transistor M3 receives the number of negative level
The number of it is believed that DATA, and now for the non-display time so the first signal VDD is 0 volt.Furthermore, return
How long the multiple time need and how low the negative level of data signal DATA need, and is all based on sampled signal Ids2
Change and determine.In other words, after learning controller 70 of the present invention repeats to receive sampled signal Ids2, depend on
Number in determining the turnaround time needed for output circuit 50 according to the change of sampled signal Ids2 and control turnaround time
The level of the number of it is believed that DATA.
Additionally, be positioned at the non-display time of display 10 turnaround time, and data signal DATA in turnaround time
Be a negative voltage, and time that data signal DATA is negative voltage need how long can also designed, designed,
The present invention is not limiting as.Refering to Fig. 2 and Fig. 3, when data signal DATA is negative voltage, drive signal
The level (0 volt) of Ids is higher than the level of data signal DATA and less than (or being same as) described second
The level of signal VSS.
As shown in the above, when showing the time, data signal DATA is that positive voltage can cause transistor
The electrical characteristic decay of M3, then the level of sampled signal Ids2 can be gradually lowered.Returning at transistor M3
The multiple time, data signal DATA is that negative voltage can make the electrical characteristic of transistor M3 gradually recover, then adopt
The level of sample signal Ids2 can gradually promote.In other words, data signal DATA can make sampled signal Ids2
Level be gradually lowered, can also gradually promote the level of sampled signal Ids2.I.e. when data signal DATA
For can be with the electrical characteristic of stabilizing output circuit 50 during negative voltage.
Referring to Fig. 4, Fig. 4 is the work driving signal, sampled signal and data signal in the embodiment of the present invention
Make time transition diagram.In conjunction with reference to Fig. 1 and Fig. 4, when showing the time, learning controller 70 is by adopting
Sample circuit 60 obtains primary sampled signal Ids2 at initial time point (t=0), and in subsequent point in time
(t=10,20 or 30 etc.) repeat to receive sampled signal Ids2, and such learning controller 70 can obtain
Sampled signal ratio.Furthermore, within the display time, door threshold value VTH (electrical characteristic) meeting of transistor M3
Increase over time and be gradually increasing, and the rising of door threshold value VTH can cause the level of sampled signal Ids2
Reduce.Therefore, the electrical characteristic recovering transistor M3 turnaround time, now learning controller 70 are utilized
Calculate sampled signal Ids2 received and calculate sampled signal ratio, and determine to reply according to sampled signal ratio
The level height of data signal DATA in the length of time and turnaround time, such as :-25 volts or-30
Volt.Additionally, the Δ VTH shown in Fig. 4 is used for representing a threshold difference, namely between door threshold value VTH
Difference.
It is the running schematic diagram of embodiment of the present invention learning controller with reference to Fig. 5, Fig. 5.As it can be seen,
The learning controller 70 of the present invention has more a learning table 72, and learning table 72 is adopted in recording the display time
The change of sample signal Ids2, the number of each turnaround time and post-sampling signal Ids2 each turnaround time
Change, such learning controller 70 control according to the record in learning table 72 output circuit 50 return
Multiple time and the level of data signal DATA in turnaround time.
Again, learning table 72 further include a comparison sampled signal ratio, one refer back to complex voltage and one with reference to reply
Time, as shown in the table:
Therefore, learning controller 70 can sampled signal Ids2 that recorded of numerology habit table 72 and obtain and adopt
Sample signal ratio (such as: 0.98), then by sampled signal than with compare sampled signal ratio and compare, so
What learning controller 70 can obtain corresponding sampled signal ratio refers back to complex voltage (-25 volts) and reference
Turnaround time (1000 seconds).Wherein, with reference to being returning of transistor M3 recovery electrical characteristic turnaround time
The multiple time, and refer back to complex voltage and be the level of data signal DATA in turnaround time, in other words, return
Multiple time correspondence is with reference to turnaround time, and data signal DATA correspondence refers back to complex voltage.So present invention shows
Show that device 10 obtains sampled signal Ids2 via sample circuit 60 and learning controller 70 calculates sampled signal
After Bi, in that case it can be decided that turnaround time and the level of data signal DATA within turnaround time.
Referring again to Fig. 5, the display time during N-1 task, the learning table of learning controller 70
72 can recording data signal DATA, the change of length and sampled signal Ids2 of display time, afterwards in the
Turnaround time during N-1 task, learning controller 70 can utilize previous record to calculate reply
The level of voltage (data signal DATA), and make learning type drive circuit 30 recover electrical characteristic.
Furthermore, at the end of the turnaround time during N-1 task, learning controller 70 can be remembered equally
Record sampled signal Ids2, and calculates sampled signal ratio, so at the end of turnaround time it is known that
Whether learning type drive circuit 30 has recovery electrical characteristic, or whether electrical characteristic is in permissible range.
If the electrical characteristic of learning type drive circuit 30 is not in permissible range, then learning table 72 also can record
In the result of N-1 task, the so turnaround time during n-th works, learning controller 70 can
With according to learning table 72 recorded data, and be increased or decreased turnaround time and within turnaround time data
The level of signal DATA, so that electrical characteristic will not dissipate, therefore can keep the display quality of display 10
