The invention is not limited in this regard. Further, the transistors in the pixel circuit may be divided into an enhancement transistor and a depletion transistor according to the conduction method of the transistors. The invention is not limited in this regard.
In addition, the present invention is described by taking the first transistor M1 in the reset sub-circuit 31 as a P-type transistor, and the other transistors are N-type transistors as examples. And, the first signal terminal ELVDD constantly outputs a high level. Where "0" represents a low level and "1" represents a high level.
In this case, the operation of the display panel shown in fig. 11 at different stages (P1 to P3) will be described in detail with reference to the signal timing chart shown in fig. 13.
In the Reset phase P1, Gate is 0, Reset is 0, Con is 1, EM is 0, and Data is 0.
In this case, the fifth transistor M5 is turned off due to a low-level signal from the scanning signal line Gate. Meanwhile, since the signal from the control signal terminal Con is at a high level, the fourth transistor M4 is turned on, and thus the first electrode of the third transistor M3 is connected to the first electrode of the first transistor M1 through the fourth transistor M4. At this time, the signal from the Reset signal terminal Reset is at a low level, the first transistor M1 is turned on, the first transistor M1 transmits the low level signal from the Reset signal terminal Reset to the first pole of the third transistor M3 through the fourth transistor M4, so that the potential of the first pole of the third transistor M3 is at a low level, thereby realizing the discharge of the third transistor M3 in the Reset phase P1, and at this time, the third transistor M3 is turned off.
In addition, due to the low level signal from the light emitting signal enable terminal EM, the second transistor M2 is turned off and the first signal terminal ELVDD is not transmitted to the fourth transistor M4, and at this time, the light emitting device L is not driven to emit light.
In summary, in the reset phase P1, the light emitting device L does not emit light.
In the data writing phase P2, Gate is 1, Reset is 1, Con is 0, and EM is 0.
In this case, the signal on the scanning signal line Gate is at a high level, so that the fifth transistor M5 is turned on, and the signal from the Data signal line Data is transmitted to the first electrode of the storage capacitor C, and the storage capacitor C is charged until the potential of the signal stored in the storage capacitor C is equal to the potential of the signal from the Data signal line Data.
At the same time, a signal from the Data signal line Data is transmitted to the gate of the third transistor M3, so that the third transistor is turned on. In this case, since the second transistor M2 is turned off by the low-level signal of the light emitting signal enable terminal EM and the fourth transistor M4 is turned off by the low-level signal of the control signal terminal Con, the signal of the first signal terminal ELVDD is not transmitted to the second transistor M2, and at this time, the light emitting device L is not driven to emit light.
Further, the first transistor M1 is turned off under the control of the high level signal of the Reset signal terminal Reset.
In summary, the light emitting device L does not emit light during the data writing phase P2.
In the light emitting phase P3, Gate is 0, Reset is 1, EM is 1, and Data is 0.
In this case, since the signal from the emission signal enable terminal EM is at a high level, the second transistor M2 is turned on to transmit the signal from the first signal terminal ELVDD to the fourth transistor M4.
Meanwhile, the storage capacitor C maintains the potential of the gate of the third transistor M3 at a high potential, so that the third transistor M3 remains turned on. The high potential is a potential of a signal from the Data signal line Data stored in the storage capacitor C in the previous stage.
On this basis, when the signal from the control signal terminal Con is at a high level, the fourth transistor M4 is turned on under the control of the high level signal from the control signal terminal Con, so that the third transistor M3 and the second transistor M2 are connected, so that the signal from the first signal terminal ELVDD is transmitted to the light emitting device L through the second transistor M2, the fourth transistor M4 and the third transistor M3, and the light emitting device L is driven to emit light.
When the signal from the control signal terminal Con is at a low level, the fourth transistor M4 is turned off under the control of the low level signal from the control signal terminal Con, so that the third transistor M3 and the second transistor M2 are not connected, and at this time, the signal from the first signal terminal ELVDD is not transmitted to the light emitting device L through the second transistor M2, the fourth transistor M4 and the third transistor M3, so that the light emitting device L is turned off to emit no light.
In summary, in the light emitting period P3, the light emitting device L emits light, and the light emitting duration of the light emitting device L is modulated by the duty ratio of the signal of the control signal terminal Con.
In order to ensure uniformity of luminance of the plurality of light emitting devices L controlled by the signal of the same control signal terminal Con, a person skilled in the art may adjust the potential of the signal of the Data signal line Data corresponding to each light emitting device L. For example, in the Data writing phase P2, the potential of the signal of the Data signal line Data is increased, and the potential of the signal stored in the storage capacitor C is also increased, so that in the light emitting phase P3, the potential of the gate of the third transistor M3 is increased, and the current of the light emitting device L electrically connected to the third transistor M3 is increased, and the light emitting luminance of the light emitting device L is increased.
In summary, in the light emitting device L of the present invention, in the light emitting period P3, the second transistor M2 and the third transistor M3 are both turned on, and in the case that the signal from the control signal terminal Con is asserted, the fourth transistor M4 is turned on, and the second transistor M2 and the third transistor M3 are electrically connected, so that the signal from the first signal terminal ELVDD can be transmitted to the light emitting device L through the second transistor M2, the fourth transistor M4 and the third transistor M3 in sequence, and the light emitting device L is driven to emit light. When the duty ratio of the control signal terminal Con is changed and the signal of the control signal terminal Con is failed, the fourth transistor M4 is turned off, and the connection between the second transistor M2 and the third transistor M3 is disconnected, so that the signal from the first signal terminal ELVDD may not be transmitted to the light emitting device L, and the light emitting device L is turned off to emit no light. Therefore, compared to the period from the beginning of the lighting period P3 to the end of the image frame, in which the light emitting device L is always lighting, and the signal of the control signal terminal Con is kept at the high level during the lighting period P3 (as shown in fig. 14), the present invention can shorten the lighting period from the beginning of the lighting period to the end of the image frame by adjusting the duty ratio of the signal of the control signal terminal Con, thereby improving the dynamic smear phenomenon due to the persistence of vision of human eyes when the display screen moves rapidly.

The control circuit 3 is located in the peripheral region S.
Wherein, each row of sub-pixels P shares the same control circuit 3. The control circuit 3 comprises a first control sub-circuit 31.
In the case where the first control sub-circuit 301 includes the Reset sub-circuit 31 and the light emission control sub-circuit 32, the Reset sub-circuit 31 connects the light emission driving circuit 32 and the Reset signal terminal Reset, and the light emission control sub-circuit 32 connects the light emission driving circuit 2, the first signal terminal ELVDD, and the light emission signal enable terminal EM.
Referring to fig. 10, the light emission driving circuit 2 further includes a data write storage sub-circuit 21.
The drive sub-circuit 20 is also electrically connected to the Data write memory sub-circuit 21, and the Data write memory sub-circuit 21 is also electrically connected to the scanning signal lines Gate and the Data signal lines Data.
The light-emitting driving circuit 2 is also electrically connected to the control signal terminal Con. In an image frame, the light-emitting control method of the display panel comprises the following steps:
in the first phase P1 of the image frame as shown in fig. 13: the Reset sub-circuit 31 transmits a signal from the Reset signal terminal Reset to the driving sub-circuit 20 under the control of a signal from the Reset signal terminal Reset.
In the second phase P2 of the image frame as shown in fig. 13: the Data write memory sub-circuit 21 stores a signal from the Data signal terminal Data under the control of a signal from the scanning signal line Gate.
In the third stage P3 of the image frame shown in fig. 13: the light-emission control sub-circuit 32 is turned on to transmit a signal from the first signal terminal ELVDD to the driving sub-circuit 20 under the control of a signal from the light-emission signal enable terminal EM; the driving sub-circuit 20 drives the light emitting device L to emit light according to the signal of the first signal terminal ELVDD, the signal of the data write-in memory sub-circuit 21, and the signal from the control signal terminal Con.
In the case where the AA area includes a plurality of display sections 101, the duty ratio of the signal from the control signal terminal Con is not completely the same for different display sections 101.
