This application claims priority to Chinese Patent Application No. 202310443599.5 filed on Apr. 23, 2023. The disclosure of the aforementioned application is incorporated herein by reference in its entirety.
The present invention relates to display technology, and more particularly, to a display panel and an electronic apparatus.
With the development of OLED (Organic Light-Emitting Diode) folding products, a dual-screen design of a primary screen and a secondary screen have been gradually adopted, and the corresponding secondary screens can be used to view basic information after the folding products are folded.
Currently, in an existing dual-screen design, the primary screen and the secondary screen are generally separately designed, which doubles the module. Besides, the primary screen and the secondary screen are indiscriminately continuously driven, so that power consumption of the driving module is large. Both of the two above facts result in an increased cost of the OLED dual-screen display.
Therefore, the conventional OLED dual-screen display suffers from the above-mentioned high-cost problem and urgently needs to be improved.

In one embodiment, as shown in
The display panel 100 may be, but is not limited to, a liquid crystal display panel or a self-luminous display panel. The self-luminous display panel may include, but is not limited to, an OLED display panel or an inorganic light-emitting diode display panel. Specifically, as shown in
Based on the above arrangement, as shown in
It will be appreciated that in the present embodiment, when the first display part 101 is in the non-display state, by setting the constant voltage control unit 303, the switching control voltage Vc, and the node control voltage Vn in conjunction with the above discussion, the output terminal G of the first gate driving unit 201 is controlled to output a constant value, i.e. the first voltage VGL, such that the waveform of the output signal corresponding to the output terminal G of the first display part 101 in the non-display state is approximately a straight line, instead of a pulse signal having a pulse in the duration of the frame, thereby effectively reducing the power consumption of the first gate driving unit 201, thereby reducing the power consumption of the gate driving module 20.
Note that in the present invention, for the plurality of first gate driving units 201 electrically connected to the first display part 101 and arranged in cascade, and the plurality of second gate driving units 202 electrically connected to the second display part 102 and arranged in cascade, the circuit of each of the plurality of first gate driving units 201 cascaded after the plurality of second gate driving units 202 is improved as described above, so that the corresponding output terminal G outputs the first voltage VGL, which, while reducing the power consumption of the gate driving module 20, may allow the first display part 101 to be in a non-display state (that is, a black screen) without affecting the normal display of the second display part 102. For ease of description herein, only the case where the plurality of first gate driving cells 201 are located after a plurality of second gate driving cells 202 will be described as an example.
In one embodiment, as shown in
As shown in
For ease of description, the invention only takes the first voltage VGL less than the second voltage VGH as an example.
In one embodiment, as shown in
Specifically, when the first display part 101 is in the non-display state, in conjunction with the above discussion, the switching control voltage Vc controls the node control voltage Vn to be transmitted to the first node Q. Further, the first output unit 301 in the present embodiment includes the first output transistor M2, and the gate of the first output transistor M2 is electrically connected to the first node Q, so that the first output transistor M2 is turned on, and at this time the source or the drain of the first output transistor M2 is loaded with the first voltage VGL, so that the first voltage VGL can be transmitted to the output terminal G through the first output transistor M2.
Note that the magnitude relationship between the node control voltage Vn and the switching control voltage Vc and their respective ranges are not limited in this embodiment. As discussed above, it is only required that the switching control voltage Vc can turn on the constant voltage control transistor M1 and the node control voltage Vn can turn on the first output transistor M2. For example, as shown in
In one embodiment, as shown in
It will be appreciated that in the present embodiment, the first output control unit 304 is further provided between the constant voltage control transistor M1 and the second node P. When the first display part 101 is in the non-display state, since the switching control voltage Vc can control the node control voltage Vn to be transmitted to the first output control unit 304, the potential of the second node P can be further controlled by the first output control unit 304, thereby controlling the second output transistor M3 to be turned off. As discussed above, even if the source or the drain of the second output transistor M3 is loaded with the second voltage VGH, the second voltage VGH cannot be transmitted to the output terminal G through the second output transistor M3 at this time, so that interference with the transmission of the first voltage VGL to the output terminal G through the first output transistor M2 is avoided, so that the potential of the output terminal G is close to the first voltage VGL.
Specifically, as shown in
Similarly, it is further required in this embodiment that the node control voltage Vn can turn on the first output control transistor M4, and that the second node control voltage Vn2 can turn off the second output transistor M3. For example, when the first output control transistor M4 and the second output transistor M3 are both P-type transistors, the node control voltage Vn and the second node control voltage Vn2 may be a lower voltage and a higher voltage, respectively. For example, the node control voltage Vn may be equal to the first voltage VGL, and the second node control voltage Vn2 may be equal to the second voltage VGH.
In one embodiment, as shown in
It will be appreciated that in the present embodiment, when the first display part 101 is in the non-display state, in conjunction with the above discussion, the switching control voltage Vc may control the node control voltage Vn to be transmitted to the gate of the second output transistor M3 to turn off the second output transistor M3, and even if the source or the drain of the second output transistor M3 is loaded with the second voltage VGH, the second voltage VGH cannot be transmitted to the output terminal G through the second output transistor M3 at this time, thereby preventing the output terminal G of the second output transistor M3 from outputting the second voltage VGH that does not meet the requirements.
Similarly, as shown in
In one embodiment, as shown in
As shown in
In particular, in the plurality of first gate driving units 201 arranged in cascade, the 1st-stage first gate driving unit 201 (i.e., the one located at a first stage) may be as discussed above. In the 1st-stage first gate driving unit 201, when the first display part 101 is in the non-display state, the gate of the second output control transistor M5 may be turned off and the connection with the output terminal of the last-stage second gate driving unit 202 (i.e., the one of the previous stage) is off, and a lower voltage (for example, equal to the first voltage VGL) is applied to prevent the pulse signal output from the output terminal of the second gate driving unit 202 at the previous stage from causing the second output control transistor M5 unable to be turned on. Regarding the 2nd-stage first gate driving unit 201, since the output terminal of the 1st-stage first gate driving unit 201 outputs the first voltage VGL (lower voltage), the second output control transistor M5 of the 2nd-stage first gate driving unit 201 can also be realized in the turned-on state to realize that the output terminal G outputs the first voltage VGL (lower voltage), and so on, each of the output terminals G of the plurality of first gate driving units 201 can output the first voltage VGL (lower voltage).
However, as discussed above, for each of the first gate driving units 201, it is still necessary to provide the constant voltage control unit 303 to control the second output transistor M3 to be turned off, thereby avoiding transmission of the second voltage VGH to the first voltage VGL to avoid interference.
In one embodiment, as shown in conjunction with
Similarly, as shown in
It will be appreciated in conjunction with the above discussion that, in the present embodiment, the constant voltage signal (for example, the first voltage VGL or the second voltage VGH) output from the output terminal G of each of the first gate driving unit 201 is applied to the gate of at least one of T1 to T7 Thereby, in combination with the switching characteristics of the transistors, it is possible to realize that the first sub-pixels P1 are in the non-light-emitting state when the first display part 101 is in the non-display state. That is, it is possible to realize that the first sub-pixels P1 are in the non-light-emitting state while reducing the power consumption of the first gate driving units 201, so that the first display part 101 is in the non-display state.
Specifically, as shown in
As shown in
Each EM-type first gate driving unit 201 may be electrically connected to a plurality of first pixel driving circuits 501 of the same stage (e.g., the same row) through a corresponding fourth sub-gate line 4014 (included in the first gate line 401) to load an EM signal of the present stage to the gate of the third switching transistor T6 therein. For example, the gate of the third switching transistor T6 in each first pixel driving circuit 501 of the nth (n is a positive integer) row may be loaded with an EM (n) signal generated by the nth-stage EM-type first gate driving unit 201.
Each Nscan-type first gate driving unit 201 may be electrically connected to a plurality of first pixel driving circuits 501 of the same stage (e.g., the same row) through a corresponding third sub-gate line 4013 (included in the first gate line 401) to load the signal Nscan of the present stage to the gate of the first switching transistor T3 therein, and may also be electrically connected to a plurality of first pixel driving circuits 501 of a certain stage (e.g., the same row) in the preceding stages through a corresponding second sub-gate line 4012 (included in the first gate line 401) to load the signal Nscan of the present stage to the gate of the second reset transistor T4 therein. For example, the gates of the first switching transistor T3 and of the second reset transistor T4 in each first pixel driving circuit 501 of the nth row may be respectively loaded with the signal Nscan (n) generated by the nth-stage Nscan-type first gate driving unit 201 and the signal Nscan (n+7) generated by the (n+7)th-stage Nscan-type first gate driving unit 201;
Each Pscan-type first gate driving unit 201 may be electrically connected to a plurality of first pixel driving circuits 501 of the same stage (e.g., the same row) through a corresponding first sub-gate line 4011 (included in the first gate line 401) so as to load the Pscan signal of the present stage to the gate of the first reset transistor T7 and the gate of the write transistor T2 therein. For example, the gate of the first reset transistor T7 and the gate of the write transistor T2 of each first pixel driving circuit 501 of the nth row may be loaded with the signal Pscan (n) generated by the nth-stage Pscan-type first gate driving unit 201.
In one embodiment, in conjunction with
Specifically, in this example, the first reset transistor T7 is a P-type transistor. It can be seen from the above discussion that when the first display part 101 is in the non-display state, since the signal Pscan (n) (equal to the first voltage VGL) transmitted by the first gate line 401 (for example, the first sub-gate line 4011) is a lower voltage, which means that the first reset transistor T7 can be controlled to be turned on, and at the same time, the third voltage VI2 can be a lower voltage, and is applied to the first sub-pixel P1 through the first reset transistor T7 (for example, the first sub-pixel P1 is an anode of an organic light-emitting diode), which would not cause the terminal voltage of the first sub-pixel P1 to reach the turn-on voltage, so that the first sub-pixel P1 is in a non-light-emitting state.
As can be seen from the above discussion, the output terminal G in the circuit diagram shown in
It will be appreciated that, as discussed above, considering that the first reset transistor T7 in
The gate of the first input transistor M6 may be connected to the first clock signal line to load the first clock signal CK1 (at this time equal to VGH) to control the first input transistor M6 to be turned off. The gate of the third control transistor M10 may be loaded with the first voltage VGL so that the third control transistor M10 is always turned on, so that the node control voltage Vn (which may be equal to VGL) is transmitted to the first node Q through the constant voltage control transistor M1 and the third control transistor M10, so that the first output transistor M2 is turned on. The first voltage VGL loaded into the source or the drain of the second output transistor M2 can be essentially the second clock signal CK2. The first voltage VGL may be transmitted to the output terminal G through the second output transistor M2. The potential of the first node Q is simultaneously pulled down due to the coupling effect of the first capacitor C1, so that the conductivity of the second output transistor M2 is also greatly increased. The output current causes the output terminal G to output the first voltage VGL. The source or the drain of the second input transistor M7 may be loaded with a first voltage VGL, and the gate of the second input transistor M7 is loaded with a first clock signal CK1 (at this time equal to VGH) to turn off the second input transistor M7. The first control transistor M8 and the second control transistor M9 are connected in series. The gate of the first control transistor M8 is electrically connected to the second node P. The source or the drain of the second control transistor M9 is electrically connected to the constant voltage control unit 303. The source or the drain of the first control transistor M8 is loaded with the second voltage VGH, and the gate of the second control transistor M9 is loaded with the second clock signal CK2 (equal to VGL at this time) to turn off the second control transistor M9. The node control voltage Vn (which may be equal to VGL) causes the first output control transistor M4 to be turned on by the constant voltage control transistor M1, and a first clock signal CK1 (which is equal to VGH or the second node control voltage Vn2 at this time) loaded by the source or the drain of the first output control transistor M4 turns off the second output transistor M3 through the first output control transistor M4. The second output transistor M3 also has a second capacitance C2 between the gate and the source (or the drain) of the second output transistor M3;
Meanwhile, in the present embodiment, when the first display part 101 is in the non-display state, the second clock signal CK2 and the first clock signal CK1 corresponding to the multi-stage Pscan-type first gate driving units 201s are set to be different constant voltage signals, respectively. When the output terminals G of the first gate driving units 201 are realized to output the first voltage VGL, the power consumption of the circuit for generating the first clock signal CK1 and the second clock signal CK2 can be further reduced, thereby further reducing the power consumption of the display panel 100.
Note that, as shown in
In one embodiment, as shown in conjunction with
Therefore, it can be considered that the second gate signal (for example, the signal Nscan (n+7) described above) and the third gate signal (for example, the signal Nscan (n) described above) are electrically connected to two first gate driving units 201 of different stages (for example, the Nscan-type first gate driving units 201), respectively, and the circuit structures of the two first gate driving units 201 are the same.
Specifically, in the case where the driving transistor T1 and the writing transistor T2 are P-type transistors, and the first switching transistor T3 and the second reset transistor T4 are N-type transistors, it can be seen from the above discussion that in a duration of the mth frame, the signal Nscan (n+7) controls the second reset transistor T4 to be turned on, and the higher fourth voltage VI1 is transmitted to the gate of the driving transistor T1 to turn off the driving transistor T1, and the maintaining module 5014 can maintain the driving transistor T1 to be turned off in a duration of the (m+1)th frame, so that when the first display part 101 is in the non-display state (for example, in the duration of the (m+1)th frame), the signal Pscan (n), the signal Nscan (n+7), and the signal Nscan (n) transmitted by the first gate line 401 (which is, for example, the first sub-gate line 4011, the second sub-gate line 4012, and the second sub-gate line 4013), respectively, are lower first voltages VGL. Although the writing transistor T2 is turned on, since the first switching transistor T3 is turned off, it is considered that the voltage loaded into the source of the driving transistor T1 (connected to the node A) cannot be transmitted to the gate of the driving transistor T1 through the first switching transistor T3, while the maintaining module 5014 can maintain the high potential of the gate of the driving transistor T1 when reset, thereby maintaining the driving transistor T1 to be stably turned off, avoiding current from flowing through the first sub-pixel P1, and enabling the first sub-pixel P1 to be in a non-light-emitting state. The maintaining module 5014 may include a maintaining capacitor C6, and two plates of the maintaining capacitor C6 are respectively connected to the gate of the driving transistor T1 and a wire loaded with a fifth voltage VDD.
As can be seen from the above discussion, the output terminal G in the circuit diagram (as the Nscan-type first gate driving unit 201) shown in
It will be appreciated that, as discussed above, considering that the first switching transistor T3 in
It can be found that in a duration of a frame T, for the Nscan-type first gate driving unit 201 of each stage corresponding to the first display part 101, since the first clock signal CK1 and the second clock signal CK2 are always equal to the same lower first voltage VGL, the third input transistors M11, M19 and the second output control transistor M5 are all turned on. Since the voltage of the gate of M13 is equal to VGL, the VGL can pass through the third input transistors M11, M13 to turn on M18, and the first clock signal CK1 equal to VGL passes through the M18, M19 to be loaded to the gate of the second output transistor M3. However, since the constant voltage control transistor M1 is additionally provided, and the switch control signal Control is always equal to the lower first voltage VGL, the constant voltage control transistor M1 can be turned on so that the VGH is loaded to the gate of the second output transistor M3 (the second node P) through the constant voltage control transistor M1 to turn off the second output transistor M3. Meanwhile, the second clock signal CK2 is equal to VGL to turn on the second output control transistor M5, and M14 is turned on, so that the second initial signal STV2 equal to VGL can be loaded to the gate (first node Q) of the first output transistor M2 through the second output control transistors M5, M14 to turn on the first output transistor M2, so that the VGL is transmitted to the output terminal G of the Pscan-type first gate driving unit 201 through the first output transistor M2;
Meanwhile, in the present embodiment, when the first display part 101 is in the non-display state, the second clock signal CK2 and the first clock signal CK1 the corresponding multi-stage Nscan-type first gate driving units 201 to the are set to be equal constant voltage signals (for example, equal to VGL), respectively. And the power consumption for generating the first clock signal CK1 and the second clock signal CK2 circuit can be further reduced while the output terminal G of the first gate driving unit 201 is realized to output the first voltage VGL, thereby further reducing the power consumption of the display panel 100.
Note that, as shown in
At first phase t1, M13, M14 are both turned on, the switch control signal Control is equal to VGH to control the transistor M1 to be turned off. The second clock signal CK2 is equal to VGL to turn on M11. The VGL is transmitted to the gate of M18 through M11, M13 to turn on M18, and the first clock signal CK1 is equal to VGH to turn off M19, so that the voltage of the second node P is maintained to be the previous voltage VGH. And at the same time, the second clock signal CK2 is equal to VGL to turn on the second output control transistor M5, the second initial signal STV2 equal to VGH is transmitted to the gate of M20 through the second output control transistor M5 to turn off M20, and transmitted to the gate (first node Q) of the first output transistor M2 through M14 to turn off the first output transistor M2, so that the voltage of the output terminal G is maintained to be a previous voltage VGL.
At second phases t2, M13, M14 are still turned on, M1 is still turned off. The second clock signal CK2 is equal to VGH to turn off M5, so that the voltage of the first node Q is maintained to be the previous voltage VGH. The second clock signal CK2 is equal to VGH to turn off M11, so that the voltage of the gate of M18 can be maintained at VGL, M18 is still on, and the first clock signal CK1 is equal to VGL to turn on M19. The first clock signal CK1 equal to VGL is transmitted to the gate of the second output transistor M3 (the second node P) through the M18, M19 to turn on the second output transistor M3, so that the VGH is transmitted to the output terminal G through the second output transistor M3.
At third phase t3, M13, M14 is still on, M1 is still off, and the second clock signal CK2 is equal to VGL to turn on the second output control transistor M5, M11, and the second initial signal STV2 equal to VGL is transmitted to the gate (first node Q) of the first output transistor M2 through the second output control transistor M5, M14 to turn on the first output transistor M2, and the M17 is turned on in a same way, and the M16 is turned on in a same way (to charge C3). The influence of threshold voltage should be taken into account after M5 is turned on. The voltage transmitted to the gate (first node Q) of the first output transistor M2 may be considered to be equal to VGL plus the above-mentioned threshold voltage, so that the conductivity of M2 is relatively small. The voltage transmitted to the output terminal G through the first output transistor M2 is between VGL and VGH, and the second initial signal STV2 is further transmitted to the gate of M20 through the second output control transistor M5 to turn on M20. VGH is transmitted to the gate (second node P) of the second output transistor M3 through M20 to turn off the second output transistor M3.
At fourth phase t4, M13, M14 is still turned on, M1 is still turned off. The second clock signal CK2 is equal to VGH to turn off M5, M11, M16, and the terminal voltage of C3 remains unchanged. Since the CK1 applied to M17 drops down to VGL, the voltage of the first node Q can be further pulled down to increase the conductivity of M2, VGL is transmitted to the output terminal G through the first output transistor M2, and the voltage of the gate of M20 is also maintained at the previous VGL to maintain M20 turned on, and VGH is transmitted to the gate of the second output transistor M3 (the second node P) through M20 to turn off the second output transistor M3.
At fifth phase t5, M13, M14 are still turned on, M1 is still turned off, M11 is turned on, M18 is turned on, M19 is turned off, M5 is turned on, M20 is turned on. VGH is transmitted to the gate (second node P) of M3 via M20 to turn off M3. M5, M11, M16, and M17 are turned on. In this case, C3 needs to be recharged, and the potential of the first node Q also fluctuates correspondingly. At sixth phase t6, the potential of the first node Q also fluctuates correspondingly.

It will be appreciated that, as discussed above, the seventh control transistor M15 may be turned on when the display panel 100 is powered on to improve the problem of screen blinking. Further, in the present embodiment, the seventh control transistor M15 may be multiuse when the first display part 101 is in the non-display state, specifically, the seventh control transistor M15 in the third output control unit is controlled to be turned on, and a higher voltage is loaded to the source or the drain of the M15 to turn off the first output transistor M2, thereby avoiding interference of the first voltage VGL with the voltage (the second voltage VGH) output from the output terminal G of the first gate driving unit 201 through the first output transistor M2.
Specifically, as discussed above, considering that the first switching transistor T3 in
For the EM-type first gate driving unit 201 of each stage corresponding to the first display part 101, since the first clock signal CK1 and the second clock signal CK2 are always equal to the same higher second voltage VGH, the third input transistors M11, M19 and the second output control transistor M5 are all turned off. The constant voltage control transistor M1 can be turned on since the constant voltage control transistor M1 is additionally provided, and the switch control signal Control is always equal to the lower first voltage VGL. In this case, the node control voltage Vn can be equal to VGL, that is, the VGL is applied to the gate (the second node P) of the second output transistor M3 through the constant voltage control transistor M1 to turn on the second output transistor M3, so that the VGH is transmitted to the output terminal G of the EM-type first gate driving unit 201 through the second output transistor M3. At the same time, the seventh control transistor M15 is controlled to be turned on, and a higher voltage (e.g., VGH) is applied to the source or the drain of the M15 to be transmitted to the gate of the first output transistor M2 (the first node Q) through the M15 to turn off the first output transistor M2.
Meanwhile, in the present embodiment, when the first display part 101 is in the non-display state, the second clock signal CK2 and the first clock signal CK1 corresponding to the multi-stage EM-type of the first gate driving unit 201 are set to be equal constant voltage signals (for example, equal to VGH), respectively. And the power consumption of the circuit for generating the first clock signal CK1 and the second clock signal CK2 can be further reduced while the voltage of the output terminal G of the first gate driving unit 201 is realized to be the second voltage VGH, thereby further reducing the power consumption of the display panel 100.
