In the embodiment of the present disclosure, the display panel may work in continuous display frames so as to display a picture. For example, one display frame may include: a plurality of row-drive time periods. Each row-drive time period may include a data writing stage T1, a light-emitting stage T2 and a black frame insertion stage T3. In other words, a row of sub-pixels corresponds to one row-drive time period, the pixel circuits in the row of sub-pixels is provided with a data writing stage T1, a light-emitting stage T2 and a black frame insertion stage T3 in the row-drive time period. Taking the pixel circuit in one sub-pixel in a row as an example below, with reference to a diagram of signal timings shown in
As shown in
At the data writing stage T1, the first transistor M1 is turned off under control of the low level of the signal loaded by the first scan signal terminal GA1. The second transistor M2 is turned on under control of the high level of the signal loaded by the second scan signal terminal GA2. The third transistor M3 is turned on under control of the high level of the signal loaded by the third scan signal terminal GA3. First, the data signal terminal DA is loaded with a first reset voltage Vf1, and the first reset voltage Vf1 is input into the gate of the drive transistor M0 through the second transistor M2 which is turned on so as to reset the gate of the drive transistor M0. Besides, the auxiliary signal terminal SE is loaded with a second reset voltage Vf2, and the second reset voltage Vf2 is input into the second electrode of the drive transistor M0 and the anode of the light-emitting device L through the third transistor M3 which is turned on so as to reset the second electrode of the drive transistor M0 and the anode of the light-emitting device L. Afterwards, the data signal terminal DA is loaded with a data voltage Vda, and the data voltage Vda is input into the gate of the drive transistor M0 through the second transistor M2 which is turned on so that a voltage of the gate of the drive transistor M0 is the data voltage Vda. Besides, the auxiliary signal terminal SE is loaded with the second reset voltage Vf2, and the second reset voltage Vf2 is input into the second electrode of the drive transistor M0 and the anode of the light-emitting device L through the third transistor M3 which is turned on so as to reset the second electrode of the drive transistor M0 and the anode of the light-emitting device L. It needs to be noted that (Vf2−Vss)<Vtholed, where, Vtholed represents a light-emitting threshold voltage of the light-emitting device L.
At the light-emitting stage T2, the first transistor M1 is turned off under control of the low level of the signal loaded by the first scan signal terminal GA1. The second transistor M2 is turned off under control of the low level of the signal loaded by the second scan signal terminal GA2. The third transistor M3 is turned off under control of the low level of the signal loaded by the third scan signal terminal GA3. Since the voltage of the gate of the drive transistor M0 is Vda and a voltage of the first electrode of the drive transistor M0 is Vdd, the drive transistor M0 generates a drive current IL: IL=K(Vda−Vdd−Vth)2, where, K is a structure parameter, and Vth represents a threshold voltage of the drive transistor M0. The drive current is input into the light-emitting device L so as to drive the light-emitting device L to emit light.
At the black frame insertion stage T3, the first transistor M1 is turned on under control of the high level of the signal loaded by the first scan signal terminal GA1. The second transistor M2 is turned off under control of the low level of the signal loaded by the second scan signal terminal GA2. The third transistor M3 is turned off under control of the low level of the signal loaded by the third scan signal terminal GA3. The black frame insertion signal terminal VB is loaded with a black frame insertion voltage Vb1a, the black frame insertion voltage Vb1a is input into the gate of the drive transistor M0 through the first transistor M1 which is turned on so as to turned off the drive transistor M0, so generation of the drive current is stopped, then the light-emitting device L stops emitting light, and thus it is switched to a black picture. It needs to be noted that Vb1a<Vth. For example, if Vth=1 V, Vb1a may be set to be 0.5 V, and Vb1a may also be set to be 0 V or a negative value, which is not limited here.
In some embodiments of the present disclosure, blanking time may be also included after the black frame insertion stage T3. Within the blanking time, the first transistor M1 may be controlled to be turned off, the second transistor M2 and the third transistor M3 may be controlled to be turned on, a detection voltage is input into the gate of the drive transistor M0 through the second transistor M2 which is turned on, so that the drive transistor M0 generates a detection current, and the detection current may be input into the auxiliary signal terminal SE through the third transistor M3 which is turned on and flow into a connected detection circuit from the auxiliary signal terminal SE. Thus, the detection circuit may be enabled to perform external compensation on the threshold voltage of the drive transistor M0 according to the detection current. It needs to be noted that a specific process of performing the external compensation on the threshold voltage of the drive transistor M0 may be basically the same as the related art and will not be repeated here.

Besides, the plurality of row-drive time periods are divided into M time period groups, and each time period group includes N row-drive time periods, wherein M≥1, N≥1, and M and N are integers. Besides, as for each time period group, the black frame insertion stage T3 in each row-drive time period in the time period group enters after the data writing stage T1 of the last row-drive time period in the time period group. In this way, all the black frame insertion stages T3 in the same time period group may enter after the data writing stage T1, writing of the data voltage is not affected, and nondestructive black frame insertion is implemented.
For example, as shown in
It needs to be noted that values of M and N may be determined according to demands of actual application and are not limited here.
In some embodiments of the present disclosure, as for each time period group, the black frame insertion stage T3 in each row-drive time period in the time period group enters after the light-emitting stage T2 of the last row-drive time period in the time period group. In this way, all the black frame insertion stages T3 in the same time period group may enter after the light-emitting stage T2, further, writing of the data voltage is not affected, and nondestructive black frame insertion is further implemented. For example, as shown in

In this way, the data voltage may be input row by row.
After the high level of the signal ga2_8 loaded by the second scan signal terminal GA2 of the eighth row of sub-pixels, after set time passes, the signals ga1_1-ga1_8 loaded by the first scan signal terminals GA1 of the first row of sub-pixels to the eighth row of sub-pixels are high levels at the same time, the second reset voltage transmitted on the black frame insertion signal line SVB is input into the gates of the drive transistors M0 of the first row of sub-pixels to the eighth row of sub-pixels, so as to control the first row of sub-pixels to the eighth row of sub-pixels to switch from light emitting to a black picture at the same time. The high levels in the signals ga1_1-ga1_8 are after the high levels in the signals ga2-1-ga2_8, so a process of inserting a black picture into the first row of sub-pixels to the eighth row of sub-pixels will not occupy time of data voltage writing, and thus a duration of data voltage writing may not be occupied.
After the high levels in the signal ga2_16 loaded by the second scan signal terminal GA2 of the sixteenth row of sub-pixels, after set time passes, the signals ga1_9-ga1_16 loaded by the first scan signal terminals GA1 of the ninth row of sub-pixels to the sixteenth row of sub-pixels are the high levels at the same time, and the second reset voltage transmitted on the black frame insertion signal line SVB is input into the gates of the drive transistors M0 of the first row of sub-pixels to the eighth row of sub-pixels, so as to control the ninth row of sub-pixels to the sixteenth row of sub-pixels to switch from light emitting to a black picture at the same time.
