Only, the 5th transistor T5 conductings, control line signal input module 50 is input into the first signal to control line CL.Wherein, if pixel is electric
Road normal work, then because data signal line DL is input into shutdown signal, the not output driving current signal of drive module 10, thus it is right
Fusing module 30 is without influence；If image element circuit has often bright bad, the meeting output driving current signal of drive module 10, mould is driven
The driving current signal of the output of block 10 can flow to earth terminal GND, so that the connection of light emitting module 20 and drive module 10 disconnects, from
And the driving current signal of the output of drive module 10 is then flowed to light emitting module 20, light emitting module 20 no longer lights.
When scan signal line SL is input into shutdown signal, during data signal line DL input data signals, the 4th transistor T4
Conducting, the 5th transistor T5 cut-offs, under the control of tertiary voltage end V3, control line signal input module 50 is defeated to control line CL
Enter secondary signal, on fusing module 30 without influence.
It should be noted that first, when the 4th transistor T4 and the 5th transistor T5 are P-type transistor, the 3rd electricity
Pressure side is then high voltage end, and the first signal is low voltage signal, and secondary signal is high voltage signal.Based on this, when fusing control
When module 40 includes third transistor T3, third transistor T3 is also P-type transistor.
When the 4th transistor T4 and the 5th transistor T5 are N-type transistor, tertiary voltage end is then low-voltage end, the

Number output；Meanwhile, the 5th transistor T5 conductings, the 4th transistor T4 cut-offs are input into low voltage signal (i.e. first to control line CL
Signal), third transistor T3 conductings, but because transistor seconds T2 is exported without driving current signal, fuse element FU two ends
Voltage is unchanged, and fuse element FU does not fuse.
When scan signal line SL is input into scanning signal, data signal line DL input shutdown signals, if transistor seconds T2
Due to design and the reason such as technology stability cause it is approximate normally opened, then as fig. 6 c, the first transistor T1 conductings, second is brilliant
Body pipe T2 has driving current signal to export；Meanwhile, the 5th transistor T5 conductings, the 4th transistor T4 cut-offs are defeated to control line CL
Enter low voltage signal, third transistor T3 conductings, the driving current signal for exporting transistor seconds T2 flows to earth terminal GND,
Now because the voltage at fuse element FU two ends changes so that fuse element FU fuses, so that luminescent device is closed.
When scan signal line SL is input into shutdown signal, data signal line DL input data signals, as shown in fig 6d, first
