[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Users can adjust the brightness of the display panel by changing the DBV of the display panel. However, when users switch DBV, the brightness is prone to fluctuation or jitter, and the screen flickers visually. For pixels with high grayscale, the brightness fluctuation is not obvious relative to the high grayscale, but for pixels with low grayscale, the brightness fluctuation is more obvious relative to the low grayscale. Users can clearly perceive the screen flickering, resulting in a poor user experience. In addition, if users switch DBV continuously, the screen flickering is more obvious.

[0028] Figure 1a It is a structural schematic diagram of a pixel driving circuit in the prior art. The pixel driving circuit is a 7T1C pixel circuit. Before initialization, the anode reset voltage is provided to the anode reset terminal (i.e., Vref110), and the cathode voltage is provided to the cathode voltage terminal (i.e., VSS120). In the initialization stage, the first initialization transistor M3 and the second initialization transistor M4 transmit the anode reset voltage of Vref 110 to the control terminal of the driving transistor M0 and the anode of the OLED element respectively, so as to initialize the control terminal of the driving transistor M0 and the anode of the OLED element; in the data writing stage, the data writing transistor M1 transmits the data voltage Vdata to the control terminal of the driving transistor M0, and the threshold compensation transistor M2 compensates the threshold voltage Vth of the driving transistor M0, and finally the voltage of the control terminal of the driving transistor M0 is Vdata+Vth, and the storage capacitor Cst stores the voltage of the control terminal of the driving transistor M0; in the light emitting stage, the first light emitting control transistor M5 and the second light emitting control transistor M6 are turned on, and the driving transistor M0 generates a driving current in response to the voltage of its own control terminal, and the OLED element emits light in response to the driving current.

[0029] The inventors have found that the effective time of the cathode voltage is later than the effective time of the anode reset voltage, resulting in brightness fluctuation or jitter. For example, Figure 1b FIG. 1 is a schematic diagram showing the effective time of the anode reset voltage and the cathode voltage in the prior art. Figure 1bAs shown, at time t1, the driving circuit sends a driving signal; at time t2, after the anode reset voltage receives the driving signal, the voltage changes, that is, the voltage changes to the desired voltage value. At time t2, after the power supply circuit receives the driving signal sent by the driving circuit, it sends a second driving signal. At time t3, after the cathode voltage receives the second driving signal, the voltage changes, that is, the voltage changes to the desired voltage value. It can be seen that the anode reset voltage takes effect earlier than the cathode voltage, resulting in different effective times for the two. When the effective time of the anode reset voltage and the cathode voltage are different, the voltage difference between the anode reset voltage and the cathode voltage near the voltage change node (for example, within the first few frames of the voltage change) will change, causing brightness fluctuations, which visually appear as flickering.

[0030] In view of the above problems, on the first aspect, an embodiment of the present application provides a method for driving a display panel, so that the difference between the effective time of the anode reset voltage and the effective time of the cathode voltage is less than the target difference (for example, the difference is 0), thereby reducing brightness fluctuations and reducing or avoiding screen flicker.

[0031] Figure 2 FIG. 1 is a flow chart of a method for driving a display panel provided by an exemplary embodiment of the present application. Figure 2 As shown, the method includes the following steps.

[0032] Step S210, providing an anode reset voltage to the anode reset terminal.

[0033] In an embodiment of the present application, an anode reset voltage is provided to the anode reset terminal (for example, Vref110 in FIG. 1 ). In an embodiment of the present application, a value range of a display brightness value of the display panel can be determined according to requirements, and a voltage change node corresponding to the cathode voltage of the display panel can be determined according to the value range. At each voltage change node, the cathode voltage and the anode reset voltage of the display panel are synchronously adjusted so that the voltage difference between the cathode voltage and the anode reset voltage is kept as the same as possible. For more descriptions on determining the voltage change node, please refer to the present application. Figure 3 and Figure 4 Related description in .

[0034] Since the effective time of the anode reset voltage is earlier than the effective time of the cathode voltage, in the embodiment of the present application, the effective time of the cathode voltage is adjusted (for example, advanced) so that the effective time of the anode reset voltage and the effective time of the cathode voltage are as close as possible. Since the cathode voltage and the anode reset voltage need to be adjusted at each voltage change node, it is necessary to ensure that the effective time of the anode reset voltage and the effective time of the cathode voltage are as close as possible at each voltage change node.

[0035] Step S220, in response to the anode reset voltage being delivered to the anode reset terminal, delivering the cathode voltage to the cathode voltage terminal within the target time, so that the difference between the effective time of the anode reset voltage and the effective time of the cathode voltage is less than the target difference.

[0036] Usually, at the voltage change node, the driving circuit will send a driving signal to the anode reset voltage, and the anode reset voltage is delivered to the anode reset terminal; at the same time, a driving signal will be sent to the power supply circuit, and the power supply circuit drives the cathode voltage, and then the cathode voltage is delivered to the cathode voltage terminal. Since the power supply circuit needs a certain time (for example, at least one frame) to drive the cathode voltage after receiving the driving signal, the effective time of the cathode voltage is later than the effective time of the anode reset voltage. In the present application, after the anode reset voltage is delivered to the anode reset terminal, the cathode voltage is delivered to the cathode voltage terminal (for example, VSS 120 in Figure 1) within the target time, so that the difference between the effective time of the anode reset voltage and the effective time of the cathode voltage is less than the target difference. Exemplarily, after the anode reset voltage is delivered to the anode reset terminal, the cathode voltage is immediately delivered to the cathode voltage terminal. The target time can be nanoseconds, microseconds, etc. In the embodiment of the present application, the target difference is a preset value, and different display devices can be different values, as long as it can be ensured that the flicker is not perceived visually. Exemplarily, the target difference can be a few microseconds, tens of microseconds, etc. Preferably, the effective time of the anode reset voltage and the effective time of the cathode voltage can be made the same, so that the anode reset voltage and the cathode voltage are effective in the same picture frame.

[0037] In an embodiment of the present application, by adjusting the time when the cathode voltage is delivered to the cathode voltage terminal, the time for delivering the cathode voltage is advanced so that the difference between the effective time of the anode reset voltage and the effective time of the cathode voltage is smaller than the target difference, so that the anode reset voltage and the cathode voltage take effect at almost the same time, thereby reducing brightness fluctuations and avoiding screen flickering.

[0038] Figure 3 FIG. 1 is a flow chart of a method for determining a voltage change node provided by an exemplary embodiment of the present application. Figure 3 As shown, the method includes the following steps.

[0039] Step S310: determining a target display brightness value interval corresponding to a target display panel.

[0040] The target display brightness value interval (i.e., DBV interval) is determined according to the requirements of different display devices. For example, for display devices with conventional brightness requirements, the display brightness value interval of the display panel can be 2 to 500 nits (nit); for display devices with high brightness requirements, the display brightness value interval of the display panel can be 2 to 1000 nits (nit). Therefore, for different display devices, the display brightness value interval of the display panel is different. In the present application, for the target display device, the target display brightness value interval corresponding to the target display panel of the target display device is determined.

[0041] Step S320, based on the target display brightness value interval, determine multiple voltage change nodes corresponding to the cathode voltage. At each voltage change node, the anode reset voltage is transmitted to the anode reset terminal (i.e. Figure 1a The cathode voltage is transmitted to the cathode voltage terminal (i.e., Vref110 in FIG. Figure 1a Optionally, at each voltage change node, the anode reset voltage is driven by the driving circuit, and the cathode voltage is driven by the power supply circuit.

[0042] In the embodiment of the present application, multiple voltage change nodes are determined based on the voltage change range of the cathode voltage within the target display brightness value interval. Specifically, Figure 4 FIG. 1 is a flow chart of a method for determining a voltage change node provided by an exemplary embodiment of the present application. Figure 4 As shown, the method includes the following steps.

[0043] Step S410 , determining two endpoint values ​​corresponding to the target display brightness value interval and cathode voltage values ​​corresponding to the two endpoint values.

[0044] In an embodiment of the present application, two endpoint values ​​can be determined according to the target display brightness value interval. For example, if the target display brightness value interval is 2 to 500 nits, the two endpoint values ​​are 2 nits and 500 nits. Determine the cathode voltage value corresponding to each of the two endpoint values. Specifically, according to the two endpoint values ​​and the voltage of the saturation region of the transistor, determine the cathode voltage value corresponding to each of the two endpoint values. For example, the cathode voltage corresponding to 2 nits is -2V, and the cathode voltage corresponding to 500 nits is -2.5V.

[0045] Step S420: determining a voltage difference between the two endpoint values ​​based on the cathode voltage values ​​corresponding to the two endpoint values.

[0046] Exemplarily, the cathode voltage values ​​corresponding to the two endpoint values ​​are subtracted to obtain the voltage difference between the two endpoint values. Since the cathode voltage changes monotonically within the entire target display brightness value interval, for example, monotonically increasing or monotonically decreasing, the voltage difference between the two endpoint values ​​is the maximum voltage difference of the entire target display brightness value interval. For example, the cathode voltage corresponding to 2 nits is -2V, and the cathode voltage corresponding to 500 nits is -2.5V, then the voltage difference between the two endpoint values ​​is 0.5V.

[0047] Step S430 , determining a plurality of voltage change nodes corresponding to the cathode voltage based on the voltage difference and the target voltage change step size.

[0048] In an embodiment of the present application, the target voltage change step size is less than or equal to 0.1V. Exemplarily, the target voltage change step size is 0.05V, 0.1V, etc.

[0049] Based on the voltage difference and the target voltage change step, multiple cathode voltage intervals can be determined, and then multiple voltage change nodes can be determined based on the multiple cathode voltage intervals. For example, the cathode voltage corresponding to 2 nits is -2V, and the cathode voltage corresponding to 500 nits is -2.5V. The voltage difference between the two endpoint values ​​is 0.5V. If the target voltage change step is 0.1V, 5 cathode voltage intervals can be determined, and the multiple voltage change nodes are determined to be -2.1V, -2.2V, -2.3V, -2.4V, and -2.5V respectively.

[0050] In the embodiment of the present application, based on the target display brightness value interval, multiple voltage change nodes corresponding to the cathode voltage are determined, and the method is simple and reliable. At each voltage change node, the anode reset voltage is driven by the driving circuit, and the cathode voltage is driven by the power supply circuit.

[0051] In some cases, due to the limitation of the driving mode of the power circuit, when adjusting the cathode voltage, the cathode voltage changes slowly, for example, in the form of a ramp (such as Figure 1b As shown); the anode reset voltage driven by the driving circuit changes rapidly, for example, it can change instantaneously (as shown Figure 1b This will also cause the voltage difference between the cathode voltage and the anode reset voltage to be different near the voltage change node, exacerbating the brightness fluctuation.

[0052] Figure 5 FIG. 1 is a flow chart of a method for driving a display panel provided by an exemplary embodiment of the present application. Figure 5 As shown, Figure 5 The methods and Figure 2 The difference between the method in is that the method further includes step S230.

[0053] In step S230, the voltage variation mode of the anode reset voltage is adjusted to be the same as the voltage variation mode of the cathode voltage, so that the voltage difference variation range between the anode reset voltage and the cathode voltage is smaller than the target voltage difference panel range.

[0054] In the embodiment of the present application, at each voltage change node, the voltage change mode of the anode reset voltage is adjusted to be the same as the voltage change mode of the cathode voltage. In the embodiment of the present application, the voltage difference between the anode reset voltage and the cathode voltage remains unchanged. Optionally, the voltage change mode of the anode reset voltage and the voltage change mode of the cathode voltage are both slope power-on modes. The slope power-on mode refers to a voltage that increases slowly (such as Figure 1b The slope in the flow is not an instantaneous change.

[0055] In an embodiment of the present application, based on the cathode voltage values ​​corresponding to the multiple voltage change nodes of the cathode voltage, the anode reset voltage values ​​corresponding to the multiple voltage change nodes are adjusted, so that the voltage change mode of the anode reset voltage is the same as the voltage change mode of the cathode voltage. Specifically, for each voltage change node, based on the cathode voltage value corresponding to the voltage change node, the anode reset voltage value corresponding to the voltage change node is adjusted, so that at each voltage change node, the voltage change step of the cathode voltage is consistent with the voltage change step of the anode reset voltage, and the voltage change time of the cathode voltage is consistent with the voltage change time of the anode reset voltage. Optionally, at different voltage change nodes, the voltage change mode of the cathode voltage is also the same, that is, the cathode voltage changes with the same voltage change step and voltage change time.

[0056] Figure 6 Schematic diagram showing the change of anode reset voltage and cathode voltage. Figure 6 As shown, at each voltage change node, the cathode voltage and the anode reset voltage change in the same manner, the voltage change step of the cathode voltage and the anode reset voltage are both ΔV, and the voltage change time of the cathode voltage and the anode reset voltage are both ΔT, so it can be ensured that the voltage difference between the cathode voltage and the anode reset voltage remains unchanged, both are ΔV0.

[0057] In an embodiment of the present application, by adjusting the time for delivering the cathode voltage to the cathode voltage terminal, the anode reset voltage and the cathode voltage take effect at almost the same time; further, the voltage change mode of the anode reset voltage is adjusted to be the same as the voltage change mode of the cathode voltage, so that the voltage difference between the anode reset voltage and the cathode voltage remains unchanged at all times, thereby avoiding brightness fluctuations and thus avoiding screen flickering.

[0060] The providing module 710 is used to provide an anode reset voltage to the anode reset terminal.

[0061] The transmission module 720 is used to transmit the cathode voltage to the cathode voltage terminal within the target time in response to the anode reset voltage being transmitted to the anode reset terminal, so that the difference between the effective time of the anode reset voltage and the effective time of the cathode voltage is less than the target difference.

[0062] Optionally, the determination module 730 is used to determine the target display brightness value interval corresponding to the target display panel; based on the target display brightness value interval, multiple voltage change nodes corresponding to the cathode voltage are determined, and at each voltage change node, the anode reset voltage is transmitted to the anode reset terminal, and the cathode voltage is transmitted to the cathode voltage terminal.

[0063] Optionally, the determination module 730 is also used to determine two endpoint values ​​corresponding to the target display brightness value interval and the cathode voltage values ​​corresponding to the two endpoint values; based on the cathode voltage values ​​corresponding to the two endpoint values, determine the voltage difference between the two endpoint values; based on the voltage difference and the target voltage change step, determine multiple voltage change nodes corresponding to the cathode voltage.

Figure 8 As shown, the driving system 800 of the display panel is different from the driving system 700 of the display panel in that it further includes an adjustment module 740 .

[0066] The adjustment module 740 is used to adjust the voltage variation mode of the anode reset voltage to be the same as the voltage variation mode of the cathode voltage, so that the voltage difference variation range between the anode reset voltage and the cathode voltage is smaller than the target voltage difference variation range.

[0067] Optionally, the adjustment module 740 is also used to adjust the anode reset voltage values ​​corresponding to the multiple voltage change nodes based on the cathode voltage values ​​corresponding to the multiple voltage change nodes of the cathode voltage, so that the voltage change mode of the anode reset voltage is the same as the voltage change mode of the cathode voltage.

[0068] Optionally, the adjustment module 740 is also used to adjust the anode reset voltage value corresponding to each voltage change node based on the cathode voltage value corresponding to the voltage change node, so that at each voltage change node, the voltage change step of the cathode voltage is consistent with the voltage change step of the anode reset voltage, and the voltage change time of the cathode voltage is consistent with the voltage change time of the anode reset voltage.
