[0002] The display panel includes multiple pixels arranged in an array. By controlling each pixel to display and emit light, the display panel can present the corresponding picture. When the display panel displays the picture, the display brightness of the display panel will be adjusted according to the actual display needs to ensure that the display panel has low power consumption while meeting the user's viewing comfort needs.

[0003] At present, the display panel has a variety of brightness adjustment modes, for example, the brightness adjustment mode of the display panel may include a direct current (DC) mode and a pulse width modulation (PWM) mode. In the DC mode, the display brightness of the display panel is adjusted by adjusting the power of each pixel in the display panel, and the greater the power, the higher the brightness, and the smaller the power, the lower the brightness; in the PWM mode, the brightness is adjusted by controlling the time for the pixel to display light, and the alternating frequency of the pixel in the light-emitting state and the non-light-emitting state is the refresh frequency of the PWM. Usually, when the display brightness of the display panel changes within a low brightness range, the PWM mode can be used to adjust the display brightness of the display panel, and when the display brightness of the display panel changes within a high brightness range, the DC mode can be used to adjust the display brightness of the display panel.

[0004] However, when the display panel needs to switch the brightness mode, the control method of the pixel display light emission in the display panel will change, resulting in a significant change in the display brightness of the display panel, which may cause the display panel to flicker and affect the display effect of the display panel. Summary of the invention

[0005] The present invention provides a display panel and a display control method, device, storage medium and display device thereof, so as to improve the screen flickering problem caused by switching of display brightness modes and enhance the display effect of the display panel.

[0006] In a first aspect, the present invention provides a display control method of a display panel, the display control method of the display panel comprising:

[0007] When the brightness adjustment mode of the display panel is switched, a first display light-emitting duty cycle of the last frame in the current brightness adjustment mode and a second display light-emitting duty cycle of the first frame in the brightness adjustment mode to be switched are obtained;

[0008] Determine the display luminous duty ratios of at least two transitional display frames inserted in the brightness switching process according to the first display luminous duty ratio and the second display luminous duty ratio; wherein the at least two transitional display frames include at least one of a first transitional display frame and a second transitional display frame; the display luminous duty ratio of the first transitional display frame is equal to the first display luminous duty ratio; the display luminous duty ratio of the second transitional display frame is equal to the second display luminous duty ratio; and the display refresh frequency of the transitional display frame is greater than or equal to the current display refresh frequency of the display panel;

[0009] According to the display luminescence duty ratios of the at least two transitional display frames, the display panel is controlled to switch the brightness adjustment mode.

[0010] In a second aspect, the present invention further provides a display control device for a display panel, the display control device for a display panel comprising:

[0011] a duty cycle acquisition module, which, when switching the brightness adjustment mode of the display panel, acquires the first display light-emitting duty cycle of the last frame in the current brightness adjustment mode and the second display light-emitting duty cycle of the first frame in the brightness adjustment mode to be switched;

[0012] a duty cycle determining module, which determines the display luminous duty cycles of at least two transitional display frames inserted in the brightness switching process according to the first display luminous duty cycle and the second display luminous duty cycle; wherein the at least two transitional display frames include the first transitional display frame and / or the second transitional display frame; the display luminous duty cycle of the first transitional display frame is equal to the first display luminous duty cycle; and the display luminous duty cycle of the second transitional display frame is equal to the second display luminous duty cycle;

[0013] The mode switching control module is used to control the display panel to switch the brightness adjustment mode according to the display light emission duty ratio of the at least two transition display frames.

[0014] In a third aspect, the present invention further provides a display device, the display device comprising: a display panel and a driving chip;

[0015] The driving chip is used to drive the display panel to display images and execute the display control method of the display panel.

[0016] In a fourth aspect, the present invention further provides a computer-readable storage medium storing computer instructions, wherein the computer instructions are used to implement the display control method of the display panel when executed by a processor.

[0017] The technical solution of the present invention is to obtain the first display luminous duty ratio of the last frame of the picture in the current brightness adjustment mode and the second display luminous duty ratio of the first frame of the picture in the brightness adjustment mode to be switched when switching the brightness adjustment mode of the display panel, and determine the display luminous duty ratio of at least two transition display frames inserted in the brightness switching process according to the first display luminous duty ratio and the second display luminous duty ratio, so that the at least two transition display frames include at least one of the first transition display frame and the second transition display frame, and the display luminous duty ratio of the first transition display frame is equal to the first display luminous duty ratio, and the display luminous duty ratio of the second transition display frame is equal to the second display luminous duty ratio. The luminous duty ratio is such that when the display panel is controlled to switch the brightness adjustment mode according to the display luminous duty ratio of at least two transitional display frames, the display luminous duty ratio of at least one transitional display frame in the at least two transitional display frames can be the same as the first display luminous duty ratio of the last frame in the current brightness adjustment mode and / or the second display luminous duty ratio of the first frame in the brightness adjustment mode to be switched, thereby improving the screen flickering problem of the display panel caused by the large change in the display luminous brightness of the display screen of the display panel due to the simultaneous change of the display luminous duty ratio and the display refresh frequency in the display panel, thereby facilitating the improvement of the display effect of the display panel. At the same time, by making the display refresh frequency of the transitional display frame greater than or equal to the current display refresh frequency of the display panel, the transitional display frame has a shorter display luminous time, so that the display panel can quickly transition from the current brightness adjustment mode to the brightness adjustment mode to be switched, and the overall display effect of the display panel is improved under the premise of ensuring that the display brightness of the display panel can transition smoothly.

[0029] It should be noted that the implementation methods provided in the embodiments of the present invention can be combined with each other if there is no contradiction.

[0030] Figure 1 is a schematic diagram of the structure of a display panel provided by an embodiment of the present invention, such as Figure 1 As shown, the display panel 100 includes a plurality of pixels 10 arranged in an array. By providing a data signal to each pixel 10 one by one, each pixel 10 can be made to display and emit light according to the data signal, so that the display panel 100 presents a corresponding picture.

[0031] It is understandable that the display panel 100 may be a self-luminous display panel or a non-self-luminous display panel, and the embodiment of the present invention does not specifically limit this. Among them, when the display panel 100 is a self-luminous display panel, the pixel 10 of the display panel 100 may include a pixel circuit and a light-emitting element, and the pixel circuit can control the light-emitting brightness of the light-emitting element according to the data signal received by it, so that the display panel 100 can present a corresponding display picture; when the display panel 100 is a non-self-luminous display panel, the pixel 10 in the display panel 100 can realize display light by reflecting or transmitting an external light source. For example, when the display panel 100 is a liquid crystal display panel, the pixel 10 of the display panel 100 may include a pixel electrode, a common electrode and a liquid crystal layer. The pixel electrode and the common electrode can generate a corresponding electric field according to the received data signal and the common voltage signal, and the electric field can control the twisting of the liquid crystal molecules in the liquid crystal layer to control the transmittance of the light provided by the backlight module, so that the pixel 10 displays light, and the display panel 100 presents a corresponding display picture. For the convenience of description, without any special limitation, the embodiments of the present invention all take the display panel being a self-luminous display panel as an example to exemplarily illustrate the technical solutions of the embodiments of the present invention.

[0032] Continue to refer Figure 1 When the display panel 100 displays an image, the display panel 100 can control the display brightness of the displayed image to change within a certain brightness adjustment range according to the light brightness of the environment in which it is located or the brightness adjustment instruction input by the user. For example, when the light brightness of the environment surrounding the display panel is strong, the display image presented by the display panel needs to have a higher display brightness so that the user can see the display image of the display panel; and when the light brightness of the environment is weak, the display image of the display panel can have a lower display brightness to prevent the display image from having a higher brightness and having higher power consumption, and affecting the user's eyesight. In this way, when the light brightness of the environment surrounding the display image changes, or when the brightness adjustment instruction input by the user changes, the display brightness of the display image presented by the display panel 100 needs to be adjusted.

[0033] Among them, the display brightness adjustment mode of the display panel may include a DC mode and a PWM mode. When the brightness adjustment mode of the display panel 100 is a DC mode, the correspondence between the brightness level (i.e., grayscale) of the pixel 10 and the voltage of the data signal can be controlled. That is, when the display panel has different display brightnesses, the voltage of the data signal corresponding to the same grayscale is different, so that the pixel circuit in the same pixel 10 provides different driving currents to the light-emitting element according to the data signal it receives, thereby adjusting the display brightness of the picture displayed by the display panel 100; when the brightness adjustment mode of the display panel 100 is a PWM mode, the ratio of the luminous time and non-luminous time of the pixel 10 can be controlled. That is, when the display panel 100 has different display brightnesses, the pixel 10 has different ratios of luminous time and non-luminous time, so that the human eye has different time integrals of the luminous brightness of the pixel 10, thereby adjusting the display brightness of the picture displayed by the display panel 100.

[0034] For example, Figure 2 is a schematic structural diagram of a pixel in a display panel provided by an embodiment of the present invention, Figure 3 is a driving timing diagram of a pixel in a display panel provided by an embodiment of the present invention, combined with reference Figure 2 and Figure 3 , the pixel 10 includes a pixel circuit P and a light-emitting element D, the pixel circuit P may include a driving transistor M1, a writing transistor M2, a compensation transistor M3, a reset transistor M4, an initialization transistor M5, a first light-emitting control transistor M6, a second light-emitting control transistor M7, a bias adjustment transistor M8, and a capacitor Cst; the reset transistor M4 can control the reset signal Vref1 to be transmitted to the gate of the driving transistor M1; the data writing transistor M2 can control the data signal to be transmitted to the first electrode of the driving transistor M1; the compensation transistor M3 can compensate for the threshold voltage Vth of the driving transistor M1; the bias adjustment transistor M8 can bias the driving transistor M1; the initialization transistor M5 can control the initialization signal Vref1 to be transmitted to the first electrode of the light-emitting element D to initialize the light-emitting element D; the first light-emitting control transistor M6 and the second light-emitting control transistor M7 can control the formation of a current path between the positive power supply signal PVDD and the negative power supply signal PVEE, so that the driving current generated by the driving transistor M1 according to its gate voltage can be provided to the light-emitting element D, driving the light-emitting element D to emit light; the storage capacitor Cst is used to store the gate voltage of the driving transistor M1.

[0035] When the display panel has a lower display refresh frequency, the driving cycle of the pixel 10 may include a refresh frame and at least one holding frame within the display time of a frame; and when the display refresh frequency of the display panel is the highest display refresh frequency that it can achieve, the driving cycle of the pixel 10 may only include a refresh frame within the display time of a frame. Wherein, taking the display panel having a lower display refresh frequency as an example, the refresh frame may include a non-luminous phase Ta10 and a luminous phase Tb10, the holding frame may include a non-luminous phase Ta20 and a luminous phase Tb20, the non-luminous phase Ta10 of the refresh frame may at least include a first bias adjustment phase Ta1, a reset phase Ta2, a second bias adjustment phase Ta3, a writing phase Ta4 and a third bias adjustment phase Ta5, the non-luminous phase Ta20 of the holding frame may include a fourth bias adjustment phase Ta6, at this time, the non-luminous time of the pixel 10 includes at least the non-luminous phase Ta10 of the refresh frame and the non-luminous phase Ta20 of the holding frame, and the luminous phase Tb10 of the refresh frame and the luminous phase Tb20 of the holding frame may both include the luminous time of the pixel 10.

[0036] In the non-luminous stage Ta10 of the refresh frame, the luminous control signal Emit is at an invalid level, so that the first luminous control transistor M6 and the second luminous control transistor M7 are in a closed state, no current is generated between the positive power signal PVDD and the negative power signal PVEE, and the luminous element D of the pixel 10 does not emit light.

[0037] In the first bias adjustment stage Ta1 of the non-luminous stage Ta10, the scanning signal SP* controls the bias adjustment transistor M8 and the initialization transistor M5 to be turned on, and the scanning signal SN2 controls the compensation transistor M3 to be turned on, so that the bias adjustment signal DVH can be written into the first electrode, the second electrode and the gate of the driving transistor M1 in sequence, so that the potentials of the first electrode, the second electrode and the gate of the driving transistor M1 are kept consistent, thereby improving the threshold drift problem of the driving transistor M1 caused by the hysteresis effect caused by the driving transistor M1 being in a biased state for a long time during the display time of the previous frame of the picture; at the same time, the initialization signal Vref2 will be written into the first electrode of the light-emitting element D to initialize the first electrode of the light-emitting element D, so as to prevent the first electrode signal of the light-emitting element D from being written into the previous frame of the picture display time, affecting the display brightness of the current display picture.

[0038] In the reset phase Ta2 of the non-light-emitting phase Ta10 , the scan signal SN1 can control the reset transistor M4 to be turned on, and the reset signal Vref1 can be transmitted to the gate of the driving transistor M1 through the reset transistor M4 to reset the gate of the driving transistor M1 .

[0039] In the second bias adjustment stage Ta3 of the non-luminous stage Ta10, the scanning signal SN1 continues to control the reset transistor M4 to be turned on. At the same time, the scanning signal SN2 controls the compensation transistor M3 to be turned on, so that the reset signal Vref1 can continue to be transmitted to the second electrode and the first electrode of the driving transistor M1 through the compensation transistor M3, so that the potentials of the first electrode, the second electrode and the gate of the driving transistor M1 remain consistent, thereby realizing the bias adjustment of the driving transistor M1 and making full preparations for the writing of the data signal Vdata.

[0040] In the writing stage Ta4 of the non-luminous stage Ta10, the scanning signal SP controls the writing transistor M2 to be turned on, and the scanning signal SN2 continues to control the compensation transistor M3 to be turned on, so that the data signal Vdata can be transmitted to the gate of the driving transistor M1 through the writing transistor M2, the driving transistor M1 and the compensation transistor M3 in sequence, and the threshold voltage of the driving transistor M1 is compensated to the gate of the driving transistor M1.

[0041] In the third bias adjustment stage Ta5 of the non-luminous stage Ta10, the scanning signal SP* controls the bias adjustment transistor M8 and the initialization transistor M5 to be turned on, so that the bias adjustment signal DVH is written to the first electrode and the second electrode of the driving transistor M1, thereby improving the display brightness difference caused by the different potentials of the first electrode and the second electrode of the driving transistor M1 of different pixels 10 due to the writing of the data signal Vdata in the writing stage Ta4; at the same time, the initialization signal Vref2 can be transmitted to the first electrode of the light-emitting element D again through the initialization transistor M5 to initialize the first electrode of the light-emitting element D, so as to prepare for the light-emitting stage Tb10.

[0042] In the light-emitting stage Tb10 of the refresh frame, the light-emitting control signal Emit can be at an effective level, so that the light-emitting control signal Emit can control the first light-emitting control transistor M6 and the second light-emitting control transistor M7 to be turned on, so that a conductive path is formed between the positive power signal PVDD and the negative power signal PVEE, and the driving transistor M1 generates a driving current according to the voltage of its gate, and the driving current is transmitted to the light-emitting element D through the second light-emitting control transistor M7 to drive the light-emitting element D to emit light.

[0043] After the light-emitting stage Tb10 of the refresh frame, the non-light-emitting stage Ta20 of the holding frame will be entered. At this time, the light-emitting control signal Emit will become an invalid level again, so that the light-emitting element D stops emitting light; in the non-light-emitting stage Ta20 of the holding frame, the scanning signals SN1, SN2 and SP will all maintain an invalid level, so that the data writing transistor M2, the reset transistor M4 and the compensation transistor M3 are always in the off state, and the gate signal of the driving transistor M1 will continue to remain as the signal written in the refresh frame; in the fourth bias adjustment stage Ta6 of the non-light-emitting stage Ta20 of the holding frame, the scanning signal SP* will again control the bias adjustment transistor M8 and the initialization transistor M5 to be turned on, so that the threshold drift caused by the driving transistor M1 being in a biased state for a long time in the light-emitting stage of the refresh frame or the previous holding frame can be improved, so as to prepare for the light-emitting stage Tb20 of the current holding frame.

[0044] After entering the light emitting stage Ta20 of the holding frame, the light emitting control signal Emit becomes a valid level again, so that the driving current generated by the driving transistor M1 can be provided to the light emitting element D, thereby driving the light emitting element D to emit light.

[0045] In this way, during the display time of a frame of the display panel with a lower display refresh frequency, the non-luminous time and the luminous time of the pixel 10 are alternated, so that the pixel 10 can present the corresponding display luminous brightness, thereby realizing the control of the display brightness of the picture displayed by the display panel.

[0046] It should be noted that the above is only an exemplary description of the structure of the pixel 10 and its driving process. The embodiment of the present invention does not specifically limit the structure of the pixel 10 and its driving process. On the premise that the core invention points of the embodiment of the present invention can be realized, technical solutions that are modified based on the structure of the pixel 10 and its driving process provided in the embodiment of the present invention all fall within the scope of protection of the embodiment of the present invention and will not be described one by one here.

[0047] Among them, continue to participate Figure 2 and Figure 3As shown, when the brightness adjustment mode of the display panel is the DC mode, the ratio of the luminous time to the non-luminous time of the pixel 10 in each frame display time can be controlled to be a fixed value. At this time, the luminous stage can include the luminous time and the non-luminous time, or only include the luminous time. By controlling the voltage of the data signal Vdata written by the write transistor M2 to the driving transistor M1 in the write stage Ta4 of the non-luminous stage Ta10 of the refresh frame, the driving current provided to the light-emitting element D during the luminous time of the luminous stage Tb10 of the refresh frame and the luminous stage Tb20 of the hold frame is controlled to control the luminous brightness of the light-emitting element D, so as to control the display luminous brightness of the picture displayed by the display panel 100; and when the brightness adjustment mode of the display panel is the PWM mode, the pixel 10 The relationship between the gray scale and the voltage of the data signal Vdata can be a fixed relationship, that is, in different brightness modes, the voltage of the data signal Vdata corresponding to the same gray scale can be the same, and the turn-on time of the first light-emitting control transistor M6 and the second light-emitting control transistor M7 in the light-emitting stage is controlled by adopting the light-emitting control signal Emit to control the time when the driving current generated by the driving transistor M1 is provided to the light-emitting element D, and the time integral of the light-emitting brightness of the light-emitting element D is controlled, so as to control the overall light-emitting brightness of the light-emitting element D within the display time of one frame of the picture, that is, the light-emitting stage may include the light-emitting time and the non-light-emitting time, and by controlling the proportion of the light-emitting time in the light-emitting stage in the display time of one frame of the picture, the display brightness of the picture displayed by the display panel can be controlled.

[0048] It should be noted that the above only provides an exemplary description of two brightness adjustment modes of the display panel. The display panel may also include other brightness adjustment modes, which can be designed according to actual needs. The embodiments of the present invention do not specifically limit this. For the convenience of description, without special limitations, the embodiments of the present invention take the brightness adjustment modes of the display panel including the DC mode and the PWM mode as an example to exemplify the technical solution of the embodiments of the present invention.

[0049] It is understandable that the specific brightness adjustment mode of the display panel can be selected according to actual needs, and the embodiment of the present invention does not specifically limit this. For example, if the brightness adjustment mode of the display panel includes a DC mode and a PWM mode, when the display panel changes within a higher display brightness range, the display panel can operate in the DC mode; and when the display panel changes between the lower display brightness ranges, the display panel can operate in the PWM mode. In this way, when the proportion of the light-emitting time in the light-emitting stage in the display time of a frame is taken as the display light-emitting duty ratio of a frame, the display light-emitting duty ratio of a frame in the DC mode can be greater than or equal to the display light-emitting duty ratio of each frame in the PWM mode, so that the holding time of the effective level of the light-emitting control signal Emit in the DC mode is greater than or equal to the holding time of the effective level of Emit in the PWM mode, that is, when the brightness adjustment mode of the display panel is the DC mode, the light-emitting control signal Emit controls the first light-emitting control transistor M6 and the second light-emitting control transistor M7 to be continuously turned on for a longer time, so that the driving transistor M1 provides the driving current to the light-emitting element D for a longer time according to the positive power supply signal of the first electrode and the gate signal thereof, while in the PWM mode, the light-emitting control signal Emit controls the first light-emitting control transistor M6 and the second light-emitting control transistor M7 to be continuously turned on for a shorter time each time, so that the driving transistor M1 provides the driving current to the light-emitting element D for a shorter time according to the positive power supply signal of the first electrode and the gate signal thereof.

[0050] However, when the driving transistor M1 generates a certain driving current, there will be a certain voltage difference between the positive power supply signal of the first electrode of the driving transistor M1 and its gate signal. The existence of this voltage difference will cause the driving transistor M1 to be in a biased state. When it is in the biased state for a long time, the threshold voltage Vth of the driving transistor M1 will drift, thereby causing the driving transistor M1 to be unable to accurately generate the driving current, thereby affecting the display brightness of the light-emitting element D. In this way, when the display panel needs to switch the brightness adjustment mode, for example, when the display panel needs to switch from DC mode to PWM mode, or from PWM mode to DC mode, the time for providing the positive power signal PVDD to the first electrode of the driving transistor M1 will change, causing the bias of the driving transistor M1 to change, and when the bias difference of the driving transistor M1 is large, it will cause a large difference in the threshold voltage drift of the driving transistor M1 in the first frame after the brightness adjustment mode is switched and the threshold voltage drift of the driving transistor M1 in the second frame. When the driving transistor M1 generates a driving current to drive the light-emitting element D to display light, there is a large difference in the display brightness of the light-emitting element D, which makes the display brightness of the two frames differ greatly, and the display panel flickers, affecting the display effect of the display panel.

[0051] Currently, when the brightness adjustment mode of the display panel changes, e.g. Figure 4 As shown, the brightness adjustment mode of the display panel is switched from DC mode to PWM mode, or, as shown in Figure 5 As shown, when the brightness adjustment mode of the display panel is switched from PWM mode to DC mode, a transition display frame will be inserted. The transition display frame can have a shorter display time, that is, the transition display frame can have a higher display refresh frequency, and the display luminescence duty cycle of the transition display frame can be between the display luminescence duty cycle before and after the brightness adjustment mode is switched.

[0052] For example, Figure 4 As shown in FIG. 1 , when the brightness adjustment mode of the display panel is switched from the DC mode to the PWM mode, if the display refresh frequency of the last frame Td in the DC mode is Fd, the display luminous duty cycle is a, and the display refresh frequency of the first frame Tp in the PWM mode is Fp, and the display luminous duty cycle is b, then a transition display frame Tg′ can be inserted between the last frame Td in the DC mode and the first frame Tp in the PWM mode, and the display refresh frequency of the transition display frame Tg′ can be Fg′, and the display luminous duty cycle can be c′. At this time, Fg′ can be simultaneously large and small. is less than or equal to Fd and Fp, c′ may be less than a and greater than b, at this time, the bias time of the driving transistor of the pixel in the transition display frame Tg′ may be between the bias time of the driving transistor of the pixel in the last frame picture Td in the DC mode and the first frame picture Tp in the PWM mode, so that the bias condition of the driving transistor of the pixel in the transition display frame Tg′ may be between the bias condition of the driving transistor of the pixel in the last frame picture Td in the DC mode and the first frame picture Tp in the PWM mode, so that the display luminous brightness under the transition display frame Tg′ can be between or Figure 5 The last frame Td in DC mode and the first frame Tp in PWM mode are used to improve the screen flickering problem caused by sudden change of brightness adjustment mode.

[0053] However, when the display refresh frequency Fg′ and the display luminous duty ratio c′ of the transition display frame Tg′ are different from the first frame Tp in the PWM mode and the last frame Td in the DC mode, when the last frame Td in the DC mode is switched to the transition display frame Tg′, the display refresh frequency Fg′ of the transition display frame Tg′ changes at the same time compared with the last frame Td in the DC mode, which makes the bias of the driving transistor in the pixel change greatly. At the same time, when the transition display frame Tg′ is switched to the first frame Tp in the PWM mode, compared with the transition display frame Td, the display refresh frequency Fg′ of the transition display frame Tg′ changes at the same time. g′, the display refresh frequency Fp and the display luminous duty cycle b of the first frame picture Tp in the PWM mode are changed, so that the bias condition of the driving transistor in the pixel also has a large change, resulting in the bias condition of the driving transistor in the display luminous time of the first frame picture Tp in the PWM mode being different from the bias condition of the driving transistor in the display luminous time of the second frame picture in the PWM mode, resulting in a difference in the display luminous brightness between the first frame picture Tp in the PWM mode and the second frame picture in the PWM mode, so that the display panel still has a high probability of screen flickering, thereby affecting the display effect of the display panel.

[0054] In order to solve the above technical problems, an embodiment of the present invention provides a display control method for a display panel, which can improve the screen flicker problem of the display panel. The display control method for a display panel of the embodiment of the present invention can control the display panel provided by the embodiment of the present invention to display a picture, and can be executed by using the display control device of the display panel provided by the embodiment of the present invention. The display control device of the display panel can be implemented by software and / or hardware, and the display control device of the display panel can be integrated in a driver chip for driving the display panel. Figure 6 is a flow chart of a display control method of a display panel provided by an embodiment of the present invention, such as Figure 6 As shown,

[0055] S10. When switching the brightness adjustment mode of the display panel, obtain the first display luminous duty ratio of the last frame in the current brightness adjustment mode and the second display luminous duty ratio of the first frame in the brightness adjustment mode to be switched.

[0056] Among them, taking the brightness adjustment mode of the display panel including the DC mode and the PWM mode as an example, switching the brightness adjustment mode of the display panel can be understood as switching from the DC mode to the PWM mode, or from the PWM mode to the DC mode. If the current brightness adjustment mode is the DC mode, the brightness adjustment mode to be switched is the PWM mode, or if the current two-point adjustment mode is the PWM mode, the brightness adjustment mode to be switched is the DC mode.

[0057] The display luminous duty cycle can be the percentage of the time that the luminous elements of the pixels in the display panel display luminescence in the display time of a frame of picture. Usually, the corresponding relationship between the grayscale of each frame of picture and the voltage of the data signal or the display luminous duty cycle can be set according to actual needs. For example, when the brightness of the environment in which the display panel is located changes within a higher brightness range, the display panel can work in DC mode, and the display panel can have a higher display luminous duty cycle when displaying the picture, and the display luminous brightness can be controlled by controlling the voltage of the data signal written to each pixel; if the brightness of the environment in which the display panel is located changes within a lower brightness range, the display panel can work in PWM mode, and the display panel can control the display luminous duty cycle of each frame of the picture according to the brightness of the environment in which it is located.

[0058] When it is necessary to switch the brightness mode of the display panel, the display luminescence duty cycle of the picture displayed by the display panel will change accordingly. At this time, the display luminescence duty cycle of the last frame of the picture in the current brightness adjustment mode can be obtained as the first display luminescence duty cycle. At the same time, the display luminescence duty cycle of the first frame of the picture in the brightness adjustment mode to be switched can be obtained as the second display luminescence duty cycle.

[0059] S20. Determine the display luminescence duty ratios of at least two transition display frames inserted in the brightness switching process according to the first display luminescence duty ratio and the second display luminescence duty ratio.

[0060] Among them, at least two transition display frames include at least one of a first transition display frame and a second transition display frame; the display luminescence duty cycle of the first transition display frame is equal to the first display luminescence duty cycle; the display luminescence duty cycle of the second transition display frame is equal to the second display luminescence duty cycle; and the display refresh frequency of the transition display frame is greater than or equal to the current display refresh frequency of the display panel.

[0061] It can be understood that the brightness switching process is the process required to go through from the last frame display image of the current brightness adjustment mode to the first frame image of the brightness adjustment mode to be switched. In this brightness switching process, at least two transition display frames can be included, that is, two or more transition display frames can be inserted between the last frame display image of the current brightness adjustment mode and the first frame image of the brightness adjustment mode to be switched. The specific design can be based on actual needs, and the embodiment of the present invention does not make specific limitations on this.

[0062] At the same time, at least two transition display frames include at least one of the first transition display frame and the second transition display frame, that is, at least two transition display frames may only include the first transition display frame, or at least two transition display frames may only include the second transition display frame, or at least two transition display frames may simultaneously include the first transition display frame and the second transition display frame, or at least two transition display frames may include other transition display frames on the premise of including at least one of the first transition display frame and the second transition display frame. The specific design can be made according to actual needs, and the embodiment of the present invention does not make any specific limitation on this.

[0063] Specifically, when at least two transition display frames include a first transition display frame, since the display luminescence duty cycle of the first transition display frame is equal to the first display luminescence duty cycle, the first transition display frame can be located between the last frame of the current brightness adjustment mode and other transition display frames, so that the last frame of the current brightness adjustment mode can be directly switched to the first transition display frame, and since the display luminescence duty cycles of the last frame of the current brightness adjustment mode and the first transition display frame are both the first display luminescence duty cycle, when switching from the last frame of the current brightness adjustment mode to the first transition display frame, and from the first transition display frame to other transition display frames or the first frame of the brightness adjustment mode to be switched, the threshold voltage drift of the driving transistor in the pixel caused by the display luminescence duty cycle can be kept consistent, and the drift difference of the threshold voltage of the driving transistor when different frames are displayed is reduced, thereby reducing the display brightness difference of different frames, improving the problem of large brightness mutation when the display screen is switched due to the simultaneous change of the display luminescence duty cycle and the refresh frequency, causing the display panel to flash, and thus improving the display effect of the display panel.

[0064] Similarly, when at least two transition display frames include a second transition display frame, since the display luminous duty cycle of the second transition display frame is equal to the second display luminous duty cycle, the second transition display frame can be located between other transition display frames and the first frame picture under the brightness adjustment mode to be switched, so that the second transition display frame can be directly switched to the first frame picture under the brightness adjustment mode to be switched, and since the display luminous duty cycles of the second transition display frame and the first frame picture under the brightness adjustment mode to be switched are both the second display luminous duty cycle, when switching from the second transition display frame to the first frame picture under the brightness adjustment mode to be switched, and from the first frame picture under the brightness adjustment mode to be switched to the second frame picture under the brightness adjustment mode to be switched, the threshold voltage drift amount of the driving transistor in the pixel can have a smaller difference, thereby reducing the display brightness difference of different frame pictures, improving the problem of large brightness mutation when the display picture is switched due to the simultaneous change of the display luminous duty cycle and the refresh frequency, causing the display panel to flicker, and thereby improving the display effect of the display panel.

[0065] It should be noted that when at least two transition display frames include a first transition display frame, the display luminescence duty cycle of the first transition display frame is equal to the first display luminescence duty cycle of the last frame in the current brightness adjustment mode. At this time, the brightness adjustment mode of the first transition display frame displayed by the display panel may be the same as or different from the current brightness adjustment mode. In an optional embodiment, when the brightness adjustment mode of the first transition display frame displayed by the display panel is the same as the current brightness adjustment mode, when the last frame in the current brightness adjustment mode is switched to the first transition display frame, there is no need to change the brightness adjustment mode of the display panel, that is, there is no need to change the driving mode of the pixels in the display panel, which is conducive to simplifying the driving mode during the picture switching process and reducing the driving cost of the display panel.

[0066] Correspondingly, when at least two transition display frames include a second transition display frame, the display luminous duty cycle of the second transition display frame is equal to the second display luminous duty cycle of the first frame in the brightness adjustment mode to be switched. At this time, the brightness adjustment mode of the second transition display frame displayed by the display panel may be the same as or different from the brightness adjustment mode to be switched. In an optional embodiment, when the brightness adjustment mode of the second transition display frame displayed by the display panel is the same as the brightness adjustment mode to be switched, when switching from the second transition display frame to the first frame in the brightness adjustment mode to be switched, there is no need to change the brightness adjustment mode of the display panel, that is, there is no need to change the driving mode of the pixels in the display panel, which is conducive to simplifying the driving mode in the picture switching process and reducing the driving cost of the display panel.

[0067] In addition, the display refresh frequency of the display panel is the number of frames of the displayed picture in a unit time. The higher the display refresh frequency of the display panel, the more frames of the displayed picture are in a unit time, the shorter the display time of each frame, the shorter the interval time of writing data signals to the driving transistor in the pixel, and the smaller the threshold voltage drift of the driving transistor in the pixel. In this way, by setting the display refresh frequency of the transition display frame to be greater than or equal to the current display refresh frequency of the display panel, the display time of the transition display frame is less than or equal to the display time of the current frame, so that the transition display frame has a shorter display time, and the threshold voltage drift of the driving transistor in the transition display frame can be reduced, so that when the transition display frame is switched to the first frame of the brightness adjustment mode to be switched, the display light emission accuracy of the light-emitting element of each pixel in the first frame can be improved, and the display quality of the display panel can be improved.

[0068] It can also be understood that the at least two transition display frames can be two transition display frames, three transition display frames, or more than three transition display frames, which can be specifically designed according to actual needs, and the embodiment of the present invention does not specifically limit this. Among them, the display refresh frequencies of each transition display frame can be the same or different. For example, when the at least two transition display frames include the first transition display frame and the second transition display frame at the same time, the display refresh frequency of the first transition display frame can be the same as or different from the display refresh frequency of the second transition display frame. Under the premise that the display refresh frequency of each transition display frame is greater than the current display refresh frequency, the embodiment of the present invention does not specifically limit this.

[0069] In an optional embodiment, when the maximum display refresh frequency of each transition display frame is F0 and the current refresh frequency of the display panel is F1, the number of transition display frames inserted during the brightness switching process may be N; wherein N≤F0 / F1, and N is a positive integer.

[0070] It can be understood that the display time of the transition display frame with the maximum refresh frequency among at least two transition display frames can be T0 / F0, and the display time of a frame at the current refresh frequency of the display panel is T0 / F1, T0 is the unit time, so that the ratio of the display time of a frame at the current refresh frequency to the display time of the transition display frame with the maximum refresh frequency is F0 / F1, that is, the time to display one frame at the current refresh frequency can display F0 / F1 frames of transition display frames with the maximum refresh frequency.

[0071] Specifically, when the number of transition display frames inserted during the brightness switching process, that is, the number of transition display frames switched between the last frame in the current brightness adjustment mode and the first frame in the brightness adjustment mode to be switched is N, the total display time of each transition display frame between the last frame in the current brightness adjustment mode and the first frame in the brightness adjustment mode to be switched can be greater than or equal to N*T0 / F0. If the total display time is large, it takes a long time to switch from the last frame in the current brightness adjustment mode to the first frame in the brightness adjustment mode to be switched, which affects the display effect of the display panel. By setting N to a positive integer less than or equal to F0 / F1, the total display time of each transition display frame can be less than or equal to (F0 / F1)*(T0 / F0), or the difference between the total display time of each transition display frame and (F0 / F1)*(T0 / F0) is small, that is, the total display time of each transition display frame can be less than or equal to the time for displaying one frame of the picture at the current display refresh frequency, or the difference between the total display time of each transition display frame and the time for displaying one frame of the picture at the current display refresh frequency is small, thereby preventing the display picture of the transition display frame from being perceived by the human eye due to the long total time of each transition display frame, thereby helping to improve the overall display effect of the display panel.

[0072] S30. Control the display panel to switch the brightness adjustment mode according to the display light emission duty ratio of at least two transition display frames.

[0073] Specifically, after the last frame of the current brightness adjustment mode is displayed, the display panel can be controlled to display each transition display frame in sequence, and after each transition display frame is displayed, the display panel can be controlled to display the first frame of the brightness adjustment mode to be switched, thereby switching the brightness adjustment mode of the display panel. The display content of each transition display frame can be the same as the display content of the last frame of the current brightness adjustment mode, or the display content of each transition display frame can be the same as the display content of the first frame of the brightness adjustment mode to be switched.

[0074] In an optional embodiment, the display panel is controlled to switch the brightness adjustment mode according to the display luminous duty cycle of at least two transition display frames, including: if the current picture of the display panel is the last frame of the current brightness adjustment mode, then after the display panel displays the current picture, the display panel is controlled to display the pictures of the transition display frames in sequence; after the display panel completes the display of each transition display frame, the display panel is controlled to display the first frame of the brightness mode to be switched.

[0075] In an exemplary embodiment, taking the at least two transition display frames including a first transition display frame and a second transition display frame as an example, Figure 7As shown, if the current brightness adjustment mode is the DC mode, the brightness adjustment mode to be switched is the PWM mode, and the current display refresh frequency of the display panel is F1, then according to the first display luminous duty cycle A of the last frame Tdn in the DC mode, it can be determined that the display luminous duty cycle of the first transition display frame Tg1 is A, and the display refresh frequency of the first transition display frame Tg1 is greater than F1, and according to the second display luminous duty cycle B of the first frame Tp1 in the PWM mode, it can be determined that the display luminous duty cycle of the second transition display frame Tg2 is B, and the display refresh frequency of the second transition display frame Tg2 is greater than F1. In this way, after entering the display time of the last frame picture Tdn in the DC mode, the data signal can be written to the gate of the driving transistor of each pixel one by one, and after the writing of the data signal is completed, the gate signal of the driving transistor will remain unchanged, so that when each pixel is controlled to display light with the first display light-emitting duty cycle, the driving transistor can provide a driving current to the light-emitting element according to its gate signal to drive the light-emitting element to emit light, thereby ensuring that the last frame picture Tdn in the DC mode can accurately display the corresponding picture; at the end moment of the display time of the last frame picture Tdn in the DC mode, the bias condition of the driving transistor of each pixel is related to the display light-emitting time of the pixel in the last frame picture Tdn in the DC mode; after completing the display of the last frame picture Tdn in the DC mode, the display time of the first transition display frame Tg1 will be entered, at which time, the data signal can be provided to each pixel one by one again, so that the signals of the gate, the first electrode and the second electrode of the driving transistor in each pixel can have a small difference The difference is that the bias state of the driving transistor in the pixel can be adjusted, and after the data signal to the pixel is written, the pixel will enter the light-emitting stage, so that the light-emitting element of each pixel can display light with the first display light-emitting duty ratio; at the end of the display time of the first transition display frame Tg1, the bias of the driving transistor of each pixel is related to the display light-emitting time of the pixel in the first transition display frame Tg1; after the picture display of the first transition display frame Tg1 is completed, the display time of the second transition display frame Tg2 will be entered, at this time, the data signal can be provided to each pixel again one by one, and each pixel can be controlled to display light with the second display light-emitting duty ratio; at the end of the display time of the second transition display frame Tg2, the bias of the driving transistor of each pixel is related to the display light-emitting time of the pixel in the second transition display frame Tg2; and so on, after the picture display of the second transition display frame Tg2 is completed, the first frame picture Tp1, the second frame picture Tp2, ... under the PWM mode will be entered in sequence.

[0076] Since the display luminous duty cycle of the first transition display frame Tg1 is the same as the first display luminous duty cycle of the last frame Tdn in the DC mode, the bias conditions of the driving transistors in each pixel can have a small difference during the display time of the last frame Tdn in the DC mode and the display time of the first transition display frame Tg1, thereby reducing the display brightness difference between the last frame Tdn in the DC mode and the first transition display frame Tg1 caused by the bias difference of the driving transistor, and thus being able to smoothly transition from the last frame Tdn in the DC mode to the first transition display frame Tg1; the display refresh frequencies of the first transition display frame Tg1 and the second transition display frame Tg2 are both greater than the current display refresh frequency, so that the display refresh frequencies of the first transition display frame Tg1 and the second transition display frame Tg2 are equal and similar, thereby during the display time of the first transition display frame Tg1 and the display time of the second transition display frame Tg2 During the period, the bias conditions of the driving transistors in each pixel can have a small difference, thereby reducing the display brightness difference between the first transition display frame Tg1 and the second transition display frame Tg2 caused by the bias difference of the driving transistor, and then smoothly transitioning from the first transition display frame Tg1 to the second transition display frame Tg2; similarly, the display luminous duty ratio of the second transition display frame Tg2 is equal to the display luminous duty ratio of the first frame picture Tp1 in the PWM mode, so that the second transition display frame Tg2 and the first frame picture Tp1 in the PWM mode can have a small display brightness difference, and the first frame picture Tp1 and the second frame picture Tp2 in the PWM mode can also have a small brightness difference, so that the second transition display frame Tg2 can smoothly transition to the first frame picture Tp1 in the PWM mode, and the first frame picture Tp1 in the PWM mode can smoothly transition to the second frame picture Tp2 in the PWM mode. In this way, by inserting at least two transition display frames in the brightness switching process, the screen flickering problem caused by the large display brightness difference between two adjacent frames can be improved, and the display effect of the display panel can be improved.

[0077] In another exemplary embodiment, continuing to take the example that at least two transition display frames include a first transition display frame and a second transition display frame, as follows: Figure 8 As shown, if the current brightness adjustment mode is the PWM mode and the brightness adjustment mode to be switched is the DC mode, then in the process of switching from the last frame Tpn of the PWM mode to the first frame Td1 of the DC mode, the first transition display frame Tg1 and the second transition display frame Tg2 will be performed in sequence. At this time, the screen flickering problem caused by the large difference in display brightness between two adjacent frames can also be improved. The specific principle is similar to the above-mentioned principle of switching from the DC mode to the PWM mode. The similarities can be referred to the above description and will not be repeated here.

[0078] It should be noted that Figure 7 and Figure 8 The example of at least two transition display frames including a first transition display frame and a second transition display frame is only used for illustrative description. In the embodiment of the present invention, the at least two transition display frames may include only the first transition display frame. In this case, at least the screen flickering problem caused by switching from the current brightness adjustment mode to the first transition display frame can be improved; or, the at least two transition display frames may include only the second transition display frame. In this case, at least the screen flickering problem caused by switching from the second transition display frame to the first frame of the brightness adjustment mode to be switched, and from the first frame of the brightness adjustment mode to be switched to the second frame of the brightness adjustment mode can be improved; or, the at least two transition display frames may also include a third transition display frame whose display luminous duty cycle is different from the first display luminous duty cycle and the second display luminous duty cycle. The specific design can be based on actual needs, and the embodiment of the present invention does not make any specific limitation on this.

[0079] Optionally, the display luminous duty cycle of at least two transition display frames inserted in the brightness switching process is determined according to the first display luminous duty cycle and the second display luminous duty cycle, including: when the current display refresh frequency is less than the preset refresh frequency, the at least two transition display frames inserted in the brightness switching process are divided into at least a first transition frame group and a second transition frame group located after the first transition frame group.

[0080] Among them, the transition display frame of the first transition frame group is the first transition display frame, and the transition display frame of the second transition frame group is the second transition display frame; the display refresh frequencies of the adjacent first transition display frame and the second transition display frame are both the set refresh frequencies; the set refresh frequency is greater than or equal to the preset refresh frequency.

[0081] Specifically, the transition display frame of the first transition frame group is the first transition display frame, so that the display luminous duty cycle of each transition display frame in the first transition frame group is the first display luminous duty cycle, that is, the display luminous duty cycle of the last frame in the current brightness adjustment mode is the same as the display luminous duty cycle of each transition display frame in the first transition frame group, so that there is a small difference between the display brightness of the last frame in the current brightness adjustment mode and the display brightness of each transition display frame in the first transition frame group, so that the last frame in the current brightness adjustment mode can be smoothly transitioned to the first transition display frame of the first transition frame group; at the same time, the transition display frame of the second transition frame group is the second transition display frame, so that the display luminous duty cycle of each transition display frame in the second transition frame group is the second display luminous duty cycle, that is, the display brightness of the first frame in the brightness adjustment mode to be switched is the same as the display brightness of the last frame in the current brightness adjustment mode. The light duty cycle is the same as the display light duty cycle of each transition display frame in the second transition frame group, so that the display brightness of the first frame in the brightness adjustment mode to be switched has a small difference with the display of each transition display frame in the second transition frame group, so that the first frame in the brightness adjustment mode to be switched can be smoothly transitioned from the second transition display frame of the second transition frame group; in addition, the display refresh frequencies of adjacent first transition display frames and second transition display frames are both set refresh frequencies, that is, the display refresh frequencies of adjacent first transition display frames are the same as the display refresh frequencies of second transition display frames, so that the display time of adjacent first transition display frames is the same as the display time of second transition display frames, so that there can be a small difference between the display brightness of the first transition display frame and the second transition display frame, so that a smooth transition can be made from the first transition display frame to the second transition display frame. In this way, first, the last frame of the current brightness adjustment mode is smoothly transitioned to the first transition display frame of the first transition frame group, and then the first transition display frame is smoothly transitioned to the second transition display frame, and finally the second transition display frame of the second transition frame group is smoothly transitioned to the first frame of the brightness adjustment mode to be switched, thereby improving the screen flickering problem caused by the large display brightness difference between each frame during the brightness switching process, improving the display uniformity of each frame, and improving the display effect of the display panel.

[0082] The set refresh frequency may be a relatively large display refresh frequency, so that when the transition display frame is at the set refresh frequency, the transition display frame can have a relatively short display time, thereby preventing the overall display content of the display panel from being affected due to the relatively long display time of the transition display frame, thereby facilitating the improvement of the display quality of the display panel. Exemplarily, when the maximum display refresh frequency of the display panel is 120 Hz, the preset refresh frequency may be 60 Hz, and the set refresh frequency may be greater than or equal to 60 Hz and less than or equal to 120 Hz.

[0083] When the current display refresh frequency of the display panel is less than the preset refresh frequency, it can be considered that the current refresh frequency of the display panel is a lower refresh frequency, so that the display time of the last frame in the current brightness adjustment mode of the display panel and the first frame in the brightness adjustment mode to be switched is longer, and the display brightness change caused by the dual change of the display time of one frame and the display luminous duty cycle is more obvious; in this way, by inserting the first transition frame group and the second transition frame group between the last frame in the current brightness adjustment mode and the first frame in the brightness adjustment mode to be switched, each time the picture is switched, only one of the display time and the display luminous duty cycle is changed, so as to ensure that the last frame in the current brightness adjustment mode can smoothly transition to the first frame in the brightness adjustment mode to be switched, thereby improving the screen flickering problem when the brightness mode of the display panel is switched, and improving the display effect of the display panel.

[0084] It can be understood that when the at least two transition display frames inserted in the brightness switching process are divided into at least a first transition frame group and a second transition frame group located after the first transition frame group, the first transition frame group may include one or more first transition display frames, and the second transition frame group may include one or more second transition display frames. The specific design can be based on actual needs, and the embodiment of the present invention does not make specific limitations on this. At the same time, the number of first transition display frames in the first transition frame group may be the same as or different from the number of second transition display frames in the second transition frame group, and the embodiment of the present invention does not make specific limitations on this.

[0085] In an optional embodiment, when the difference between the current display refresh frequency and the set refresh frequency is greater than the preset frequency difference, the first transition frame group includes at least two first transition display frames; wherein the two adjacent first transition display frames are respectively a first first transition display frame and a second first transition display frame located after the first first transition display frame; the display refresh frequency of the first first transition display frame is greater than the current display refresh frequency; and the display refresh frequency of the second first transition display frame is greater than the display refresh frequency of the first first transition display frame.

[0086] It can be understood that the first transition frame group includes at least two first transition display frames, that is, the first transition frame group can include two, three or more first transition display frames, which can be designed according to actual needs, and the embodiment of the present invention does not specifically limit this; at the same time, when two adjacent first transition display frames are respectively the first first transition display frame and the second first transition display frame, the second first transition display frame is located after the first first transition display frame, so that after the picture display of the first first transition display frame is completed, the picture display of the second first transition display frame is performed; and the display refresh frequency of the second first transition display frame is greater than the display refresh frequency of the first first transition display frame, that is, the display refresh frequency of each first transition display frame between the last frame of the picture and the second transition display frame in the current brightness adjustment mode can be gradually increased so as to be able to gradually transition from the current display refresh frequency to the set refresh frequency.

[0087] Specifically, Fig. 9 (or Fig.10), taking the first transition frame group Tg10 including two first transition display frames Tg1, namely the first first transition display frame Tg101 and the second first transition display frame Tg102 as an example, when the current display refresh frequency is less than the preset refresh frequency, it can be determined that the current display refresh frequency is a smaller refresh frequency, and the set refresh frequency is usually a larger refresh frequency, so that the second first transition display frame Tg102 whose display refresh frequency is the set refresh frequency has a certain difference with the display refresh frequency of the last frame Tdn (or TPn) in the current brightness adjustment mode. When the difference is large, there is a large time difference between the display time of the last frame Tdn (or TPn) in the current brightness adjustment mode and the display time of the second first transition display frame Tg102 whose display refresh frequency is the set refresh frequency. The existence of the time difference will cause a certain display brightness difference between the last frame Tdn (or TPn) in the current brightness adjustment mode and the second first transition display frame Tg102 whose display refresh frequency is the set refresh frequency. At this time, the first first transition display frame Tg101 with a display refresh frequency between the set refresh frequency and the current display refresh frequency can be inserted between the last frame Tdn (or TPn) of the current brightness adjustment mode and the second first transition display frame Tg102 with a display refresh frequency of the set refresh frequency. In this way, the display time of the last frame Tdn (or TPn) of the current brightness adjustment mode and the first first transition display frame Tg101 has a small difference, so as to reduce the display brightness difference between the last frame Tdn (or TPn) of the current brightness adjustment mode and the first first transition display frame Tg101 caused by the difference in display time. At the same time, the display time of the first first transition display frame Tg101 and the second first transition display frame Tg102 also has a small difference, so that the display brightness difference between the first first transition display frame Tg101 and the second first transition display frame Tg102 is small, so that the last frame Tdn (or TPn) of the current brightness adjustment mode can be smoothly transitioned to the second first transition display frame Tg102, thereby improving the screen flicker problem and improving the display effect of the display panel.

[0088] It should be noted that Fig. 9 and Fig.10 The first transition frame group includes two first transition display frames, and the number of first transition frames in the first transition frame group is not specifically limited in the embodiment of the present invention. Fig.11 or Fig.12The first transition frame group may include N first transition display frames (Tg11, Tg12, Tg13, ..., Tg1N), where N may be a positive integer greater than or equal to 3. In this case, the display refresh frequency of the first transition display frame Tg12 may be greater than the display refresh frequency of the first transition display frame Tg11, the display refresh frequency of the first transition display frame Tg13 may be greater than the display refresh frequency of the first transition display frame Tg12, and so on. The display refresh frequency of the first transition display frame Tg1N may be greater than the refresh frequencies of the other first transition display frames, so that the last frame Tdn (or TPn) of the current brightness adjustment mode smoothly transitions to the first transition display frame Tg1N.

[0089] It should also be noted that when the first transition frame group includes three or more first transition display frames, the difference between the display refresh frequencies of any two adjacent first transition display frames can be a fixed value or a non-fixed value, which can be specifically designed according to actual needs, and the embodiment of the present invention does not specifically limit this. In an optional embodiment, the increase in the display refresh frequency of each first transition display frame can be gradually increased to reduce the number of set first transition display frames while ensuring a smooth transition of each frame. In another optional embodiment, the difference between the display refresh frequencies of any two adjacent first transition display frames is equal, so as to simplify the driving method of the display panel.

[0090] Optional, reference Fig. 9 and Fig.10 In any of the figures, the difference between the display refresh frequency of the first first transition display frame Tg101 and the current display refresh frequency is the first frequency difference; the difference between the display refresh frequency of the second first transition display frame Tg102 and the display refresh frequency of the first first transition display frame Tg101 is the second frequency difference; wherein the first frequency difference and the second frequency difference are both within the preset frequency difference range.

[0091] It is understandable that the preset frequency difference range can be a smaller value range. When the difference between the display refresh frequencies of two adjacent frames is within the preset frequency difference range, the display brightness difference caused by the different display refresh frequencies is smaller. For example, the display brightness difference is not easily perceived by the human eye. In an exemplary embodiment, the upper limit of the preset frequency difference range can be less than or equal to 60 Hz, and the lower limit of the preset frequency difference range can be greater than 0 Hz.

[0092] Specifically, refer to Fig. 9 (or Fig.10), the display refresh frequency of the last frame Tdn (or Tpn) in the current brightness adjustment mode is the current display refresh frequency, and the first frequency difference between the display refresh frequency of the first first transition display frame Tg101 and the current display refresh frequency is set within the preset frequency difference range, so that the display brightness difference between the first first transition display frame Tg101 and the last frame Tdn (or Tpn) in the current brightness adjustment mode caused by the different display refresh frequencies is small, so that when the last frame Tdn (or Tpn) in the current brightness adjustment mode is switched to the first first transition display frame Tg101, the display brightness change between the two frames can be reduced; at the same time, the second second transition display frame Tg1 The second frequency difference between the display refresh frequency of the first transition display frame Tg102 and the display refresh frequency of the first transition display frame Tg101 is set within the preset frequency difference range, which can reduce the display brightness difference between the second transition display frame Tg102 and the first transition display frame Tg101 caused by the different refresh frequencies, thereby reducing the display brightness change between the two frames when switching from the first transition display frame Tg101 to the second transition display frame Tg102; in this way, by setting the frequency difference between the display refresh frequencies of two adjacent frames within the preset frequency difference range, it is possible to have a smaller display brightness difference between the two adjacent frames, thereby improving the screen flicker problem and improving the display effect of the display panel.

[0093] In another optional embodiment, when the difference between the current display refresh frequency and the set refresh frequency is greater than the preset frequency difference, the second transition frame group includes at least two second transition display frames; wherein two adjacent second transition display frames are respectively the first second transition display frame and the second second transition display frame; the display refresh frequency of the first second transition display frame is greater than the display refresh frequency of the second second transition display frame; and the display refresh frequency of the second second transition display frame is greater than the current display refresh frequency.

[0094] It can be understood that the second transition frame group includes at least two second transition display frames, that is, the second transition frame group can include two, three or more second transition display frames, which can be specifically designed according to actual needs, and the embodiment of the present invention does not specifically limit this; at the same time, when two adjacent second transition display frames are respectively the first second transition display frame and the second second transition display frame, the second second transition display frame is located after the first second transition display frame, so that after the picture display of the first second transition display frame is completed, the picture display of the second second transition display frame is performed; and the display refresh frequency of the second second transition display frame is greater than the display refresh frequency of the first second transition display frame, that is, the display refresh frequency of each second transition display frame between the first transition display frame and the first frame in the brightness adjustment mode to be switched can be gradually increased so as to be able to gradually transition from the set refresh frequency to the current display refresh frequency.

[0095] Specifically, Fig.13 (or Fig.14), taking the second transition frame group Tg20 including two second transition display frames Tg2, namely the first second transition display frame Tg201 and the second second transition display frame Tg202 as an example, when the current display refresh frequency is a smaller refresh frequency than the preset refresh frequency, the difference between the display refresh frequency of the first and second transition display frames Tg201 whose display refresh frequency is the set refresh frequency and the display refresh frequency of the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched is a larger value, so that there is a larger time difference between the display time of the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched and the display time of the first and second transition display frames Tg201 whose display refresh frequency is the set refresh frequency. The existence of this time difference will cause a certain display brightness difference between the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched and the first and second transition display frames Tg201 whose display refresh frequency is the set refresh frequency. At this time, a second second transition display frame Tg202 having a display refresh frequency between the set refresh frequency and the current display refresh frequency can be inserted between the first second transition display frame Tg201 having a display refresh frequency of the set refresh frequency and the first frame image Tp1 (or Td1) of the brightness adjustment mode to be switched. In this way, the display time of the first second transition display frame Tg201 and the second second transition display frame Tg202 has a small difference, so as to reduce the display brightness difference between the first second transition display frame Tg201 and the second second transition display frame Tg202 caused by the difference in display time. At the same time, the display time of the second second transition display frame Tg202 and the first frame picture Tp1 (or Td1) of the brightness adjustment mode to be switched also has a small difference, so that there is a small display brightness difference between the second second transition display frame Tg202 and the first frame picture Tp1 (or Td1) of the brightness adjustment mode to be switched, so that the first second transition display frame Tg201 can smoothly transition to the first frame picture Tp1 (or Td1) of the brightness adjustment mode to be switched, thereby improving the screen flicker problem and improving the display effect of the display panel.

[0096] It should be noted that Fig.13 and Fig.14 The second transition frame group includes two second transition display frames, and the number of second transition frames in the second transition frame group is not specifically limited in the embodiment of the present invention. Fig.15 or Fig.16The second transition frame group may include M second transition display frames (Tg21, Tg22, Tg23, ..., Tg2M), where M may be a positive integer greater than or equal to 3. In this case, the display refresh frequency of the second transition display frame Tg22 may be greater than the display refresh frequency of the second transition display frame Tg21, the display refresh frequency of the second transition display frame Tg23 may be greater than the display refresh frequency of the second transition display frame Tg22, and so on. The display refresh frequency of the second transition display frame Tg2M may be greater than the refresh frequencies of the other second transition display frames, so that the second transition display frame Tg21 can smoothly transition to the first frame Tp1 (or Td1) of the brightness adjustment mode to be switched.

[0097] It should also be noted that when the second transition frame group includes three or more second transition display frames, the difference between the display refresh frequencies of any two adjacent second transition display frames can be a fixed value or a non-fixed value, which can be specifically designed according to actual needs, and the embodiment of the present invention does not specifically limit this. In an optional embodiment, the increase in the display refresh frequency of each second transition display frame can be gradually increased to reduce the number of second transition display frames set while ensuring a smooth transition of each frame. In another optional embodiment, the difference between the display refresh frequencies of any two adjacent second transition display frames is equal, so as to simplify the driving method of the display panel.

[0098] Optional, reference Fig.13 and Fig.14 In any of the figures, the difference between the display refresh frequency of the first second transition display frame Tg201 and the display refresh frequency of the second second transition display frame Tg202 is the third frequency difference; the difference between the display refresh frequency of the second second transition display frame Tg202 and the current display refresh frequency is the fourth frequency difference; wherein the third frequency difference and the fourth frequency difference are both within the preset frequency difference range.

[0099] Specifically, the display refresh frequency of the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched is the current display refresh frequency, and the third frequency difference between the display refresh frequency of the first second transition display frame Tg201 and the display refresh frequency of the second second transition display frame Tg202 is set within the preset frequency range, so that the display brightness difference between the first second transition display frame Tg201 and the second second transition display frame Tg202 caused by the different display refresh frequencies is smaller, so that when switching from the first second transition display frame Tg201 to the second second transition display frame Tg202, the display brightness change between the two frames can be reduced; at the same time, the display refresh frequency of the second second transition display frame Tg202 is adjusted to the brightness adjustment mode to be switched. The fourth frequency difference between the display refresh frequencies of the first frame image Tp1 (or Td1) in the mode is set within a preset frequency range, so that the display brightness difference between the second second transition display frame Tg202 and the first frame image Tp1 (or Td1) in the brightness adjustment mode to be switched due to the different display refresh frequencies is smaller, thereby reducing the display brightness change between the two frames when switching from the second second transition display frame Tg202 to the first frame image Tp1 (or Td1) in the brightness adjustment mode to be switched; in this way, by setting the frequency difference between the display refresh frequencies of two adjacent frames within the preset frequency difference range, a smaller display brightness difference can be made between the two adjacent frames, thereby improving the screen flicker problem and improving the display effect of the display panel.

[0100] It should be noted that the above is only exemplarily described by taking the first transition frame group including multiple first transition display frames and the second transition frame group including one second transition display frame, or the first transition frame group including one first transition display frame and the second transition frame group including multiple second transition display frames as an example. In the embodiment of the present invention, Fig.17 or Fig.18 As shown, the first transition frame group Tg10 may include N frames of first transition display frames Tg1, and the second transition frame group Tg20 may include M frames of second transition display frames Tg2, wherein M and N are both positive integers greater than or equal to 2, and M and N may be the same or different. The specific design can be based on actual needs, and the embodiment of the present invention does not make any specific limitation on this.

[0101] In addition, the above is only an exemplary description of at least two transition display frames located between the last frame in the current brightness adjustment mode and the first frame in the brightness adjustment mode to be switched, including at least one first transition display frame and at least one second transition display frame. In the embodiment of the present invention, other transition display frames can be set between the first transition display frame and the second transition display frame, which can be designed according to actual needs, and the embodiment of the present invention does not make specific limitations on this.

[0102] For ease of description, without special limitations, the embodiments of the present invention take the first transition frame group including N frames of first transition display frames and the second transition frame group including M frames of second transition display frames as an example to exemplarily illustrate the technical solutions of the embodiments of the present invention.

[0103] Optionally, when the difference between the first display luminous duty cycle and the second display luminous duty cycle is greater than a preset duty cycle difference, the at least two transition display frames also include at least one third transition display frame located between the first transition display frame and the second transition display frame; the display luminous duty cycle of the third transition display frame is between the first display luminous duty cycle and the second display luminous duty cycle; and the display refresh frequency of the third transition display frame is the set refresh frequency.

[0104] It is understandable that the preset duty cycle difference can be a larger value, for example, the preset duty cycle difference can be greater than or equal to 30%, and can be specifically designed according to actual needs, and the embodiment of the present invention does not specifically limit this. When the difference in the display luminous duty cycle between two adjacent frames is greater than the preset duty cycle difference, the difference in the display luminous duty cycle between the two adjacent frames is large, and the difference in display luminous brightness caused by the different display luminous duty cycles is large. At this time, the display luminous duty cycle can be inserted between the two frames to connect other display pictures between the two adjacent frames, so that the display brightness of each frame can be smoothly transitioned, thereby improving the display uniformity of the display panel.

[0105] Specifically, refer to Fig.19 and Fig. 20In any of the accompanying drawings, since the display luminous duty ratio of each first transition display frame Tg1 in the first transition frame group T10 is the first display luminous duty ratio, and the display luminous duty ratio of each second transition display frame Tg2 in the second transition frame group T20 is the second display luminous duty ratio, the display luminous duty ratio of the first transition display frame Tg1 in the first transition frame group T10 and the second transition display frame Tg2 in the second transition frame group T20 have a certain difference. When the difference is greater than the preset duty ratio difference, if the last frame of the first transition display frame Tg1N in the first transition frame group T10 is directly switched to the second transition display frame Tg2, the display luminous duty ratio of the first transition display frame Tg1 in the first transition frame group T10 is greater than the preset duty ratio difference. The first frame and the second transition display frame Tg21 of the transition frame group Tg20 will have a larger difference in display brightness between the two frames due to the larger difference in display luminous duty ratio between the two frames; at this time, by inserting the third transition display frame Tg3 between the last frame, the first transition display frame Tg1N in the first transition frame group T10 and the first frame and the second transition display frame Tg21 of the second transition frame group Tg20, and the display luminous duty ratio of the third transition display frame Tg3 is between the first display luminous duty ratio and the second display luminous duty ratio, and the third transition display frame Tg3 The display refresh frequency of the first transition frame group T10 and the display refresh frequency of the first frame and the second frame of the second transition frame group Tg20 are all set refresh frequencies, so that the display luminous duty ratios of the last frame and the third transition frame Tg1N in the first transition frame group T10 and the third transition frame Tg3 have a small difference, and the display luminous duty ratios of the third transition frame Tg3 and the first frame and the second transition frame Tg21 of the second transition frame group Tg20 have a small difference, thereby reducing the display luminous duty ratios caused by the display. The display brightness difference between the last frame, the first transition display frame Tg1N, and the third transition display frame Tg3 in the first transition frame group T10 caused by the display luminous duty cycle is reduced, and the display brightness difference between the third transition display frame Tg3 and the first frame, the second transition display frame Tg21 of the second transition frame group Tg20 caused by the display luminous duty cycle is reduced, so that a smooth transition can be made from the last frame, the first transition display frame Tg1N in the first transition frame group T10 to the first frame, the second transition display frame Tg21 of the second transition frame group Tg20, thereby improving the screen flicker problem and enhancing the display effect of the display panel.

[0106] It should be noted that Fig.19 and Fig. 20 The example of inserting a third transition display frame between the first transition frame group and the second transition frame group is only used for illustration. In the embodiment of the present invention, the number of third transition display frames inserted between the first transition frame group and the second transition frame group can be designed according to actual needs, and the embodiment of the present invention does not make any specific limitation on this.

[0107] In an exemplary embodiment, if Fig.21 or Fig. 22 , K third transition display frames Tg3 (Tg31, ..., Tg3K) may be arranged between the first transition frame group Tg10 and the second transition frame group Tg20, K may be any positive integer, at this time, the display luminescence duty cycle of each third transition display frame Tg3 may be between the first display luminescence duty cycle and the second display luminescence duty cycle, and in two adjacent third transition display frames Tg3, when the absolute value of the difference between the display luminescence duty cycle of the third transition display frame Tg3 of the previous frame and the first display luminescence duty cycle is the first duty cycle, and when the difference between the display luminescence duty cycle of the third transition display frame Tg3 of the next frame and the first display luminescence duty cycle is the second duty cycle, the first duty cycle may be smaller than the second duty cycle, so that the display luminescence duty cycle of the third transition display frame Tg3 close to the first transition display frame Tg1 has a larger difference with the first display luminescence duty cycle. A small difference can be obtained, thereby ensuring that when the adjacent first transition display frame Tg1 and the third transition display frame Tg3 perform screen switching, there can be a smaller brightness change; similarly, in two adjacent third transition display frames Tg3, when the absolute value of the difference between the display luminescence duty cycle of the previous third transition display frame Tg3 and the second display luminescence duty cycle is the third duty cycle, and when the difference between the display luminescence duty cycle of the next third transition display frame Tg3 and the second display luminescence duty cycle is the fourth duty cycle, the fourth duty cycle can be smaller than the third duty cycle, thereby ensuring that when the adjacent third transition display frame Tg3 and the second transition display frame Tg2 perform screen switching, there can be a smaller brightness change.

[0108] In an optional embodiment, the difference in display luminous duty cycle between adjacent first transition display frames and third transition display frames is ΔDuty1; the difference in display luminous duty cycle between adjacent third transition display frames and second transition display frames is ΔDuty2; wherein ΔDuty1 and ΔDuty2 are both within a preset duty cycle difference range.

[0109] Among them, the preset duty cycle difference range can be understood as a smaller difference range. For example, the upper limit of the preset duty cycle difference range can be less than or equal to 30%, and the lower limit of the preset duty cycle difference range can be greater than or equal to -30%. It can be designed according to actual needs, and the embodiment of the present invention does not make specific limitations on this. It can be understood that when the display luminous duty cycle of two adjacent frames is within the preset duty cycle difference range, the display brightness difference caused by the difference in the display luminous duty cycle of the two frames is small.

[0110] Specifically, refer to Fig.21 or Fig. 22In each third transition display frame Tg3, the first frame third transition display frame Tg31 is adjacent to the first transition display frame Tg1. At this time, the difference ΔDuty1 between the display luminous duty cycle of the first frame third transition display frame Tg31 and the first transition display frame Tg1 can be within the preset duty cycle difference range, so that the display luminous duty cycle of the first frame third transition display frame Tg31 and the first transition display frame Tg1 has a smaller difference, so that the brightness difference caused by the difference between the display luminous duty cycle of the first frame third transition display frame Tg31 and the first transition display frame Tg1 is smaller, so that when switching from the first transition display frame Tg1 to the first frame third transition display frame Tg31, the display panel can have a smaller display brightness change Similarly, the last frame of the third transition display frame Tg3K is adjacent to the second transition display frame Tg2. At this time, the difference ΔDuty2 between the display luminous duty cycle of the last frame of the third transition display frame Tg3K and the second transition display frame Tg2 can be within the preset duty cycle difference range, so that the display luminous duty cycle of the last frame of the third transition display frame Tg3K and the second transition display frame Tg2 has a smaller difference, so that the brightness difference caused by the difference between the display luminous duty cycle of the last frame of the third transition display frame Tg3K and the second transition display frame Tg2 is smaller, so that when switching from the last frame of the third transition display frame Tg3K to the second transition display frame Tg2, the display panel can have a smaller display brightness change.

[0111] In addition, when a plurality of third transition display frames Tg3 are provided between the first transition frame group Tg10 and the second transition frame group Tg20, the difference ΔDuty3 between the display luminous duty ratios of two adjacent third transition display frames Tg3 can also be within the preset duty ratio difference range, so that when the display screen of the display panel switches between two adjacent third transition display frames Tg3, it can also have a smaller display brightness change, thereby improving the stroboscopic problem of the display panel and improving the display effect of the display panel. Among them, ΔDuty1, ΔDuty2 and ΔDuty3 can be the same or different, and can be designed according to actual needs, and the embodiment of the present invention does not specifically limit this.

[0112] It can be understood that when a third transition display frame Tg3 consisting of multiple frames is set between the first transition frame group Tg10 and the second transition frame group Tg20, the brightness adjustment mode of the third transition display frame (Tg31) closer to the first transition display frame Tg1 can be the same as the brightness adjustment mode of the first transition display frame Tg1, and / or, the brightness adjustment mode of the third transition display frame (Tg3K) closer to the second transition display frame Tg2 can be the same as the brightness adjustment mode of the second transition display frame Tg2, so as to simplify the driving method of the display panel without repeatedly switching the brightness adjustment mode of each transition display frame.

[0113] In an optional embodiment, the brightness adjustment mode of at least a portion of the third transition display frame Tg3 is the brightness adjustment mode to be switched.

[0114] In an exemplary embodiment, Fig.21 As shown, when the brightness adjustment mode to be switched is the PWM mode, the brightness adjustment mode of at least part of the third transition display frames Tg3 can also be set to the PWM mode, so that each third transition display frame Tg3 can have the same corresponding relationship between the voltage and grayscale of the data signal. When driving the display panel to display the picture, it is only necessary to change the display luminescence duty cycle of each third transition display frame Tg3, which is conducive to simplifying the driving method of the display panel.

[0115] In another exemplary embodiment, Fig. 22 As shown, when the brightness adjustment mode to be switched is the DC mode, the brightness adjustment mode of at least part of the third transition display frame Tg3 can be set to the DC mode, so that when the display content of the third transition display frame Tg3 is the same as the display content of the brightness adjustment mode to be switched, the data signal provided to each pixel when displaying the third transition display frame Tg3 can be consistent with the data signal provided to each pixel when displaying the first frame of the brightness adjustment mode to be switched, and the display light-emitting duty cycle can be adjusted by only adjusting the light-emitting time of each pixel, which is also conducive to simplifying the driving method of the display panel.

[0116] It can be understood that in the embodiment of the present invention, the brightness adjustment mode of at least part of the third transition display frames is the brightness adjustment mode to be switched, that is, the brightness adjustment mode of all third transition display frames can be set to the brightness adjustment mode to be switched, or only the brightness adjustment mode of part of the third transition display frames close to the second transition display frame can be set to the brightness adjustment mode to be switched. The specific design can be based on actual needs, and the embodiment of the present invention does not make specific limitations on this.

[0117] It should be noted that the above only exemplarily illustrates the technical solution of the embodiment of the present invention by taking the current display refresh frequency of the display panel as a smaller display refresh frequency as an example, and the brightness switching process when the current display refresh frequency of the display panel is a larger display refresh frequency can be the same as or different from the above process, and can be specifically designed according to actual needs, and the embodiment of the present invention does not make specific limitations on this.

[0118] Optionally, determining the display luminous duty cycle of at least two transition display frames inserted in the brightness switching process according to the first display luminous duty cycle and the second display luminous duty cycle also includes: when the current display refresh frequency is greater than or equal to the preset refresh frequency, determining the two transition display frames inserted in the brightness switching process; the two transition display frames are respectively the first transition display frame and the fourth transition display frame located after the first transition display frame; the display refresh frequencies of the first transition display frame and the fourth transition display frame are both the set refresh frequencies; the set refresh frequency is greater than the current display refresh frequency; the display luminous duty cycle of the fourth transition display frame is between the display luminous duty cycle of the first transition display frame and the second display luminous duty cycle.

[0119] It can be understood that when the current display refresh frequency is greater than or equal to the preset refresh frequency, the current display refresh frequency can be determined to be a larger display refresh frequency, so that the current display refresh frequency is the same or close to the display refresh frequency of the transition display frame, so that when switching from the last frame in the current brightness adjustment mode to the transition display frame, or from the transition display frame to the first frame in the brightness adjustment mode to be switched, the change in display brightness caused by the different display refresh frequencies is smaller.

[0120] Among them, Fig.23 (or Fig.24), by making at least two transition display frames inserted between the last frame Tdn (or Tpn) in the current brightness adjustment mode and the first frame Td1 (or Tp1) in the brightness adjustment mode to be switched include a first transition display frame Tg1 and a fourth transition display frame Tg4, the display luminous duty cycle of the first transition display frame Tg1 and the display luminous duty cycle of the last frame Tdn (or Tpn) in the current brightness adjustment mode are both the first display luminous duty cycle, and the display refresh frequency of the first transition display frame Tg1 and the display refresh frequency of the last frame Tdn (or Tpn) in the current brightness adjustment mode are both greater than the preset refresh frequency, so that when switching from the last frame Tdn (or Tpn) in the current brightness adjustment mode to the first transition display frame Tg1, there can be a smaller change in display brightness; at the same time, the display refresh frequencies of the first transition display frame Tg1 and the fourth transition display frame Tg4 can both be the set refresh frequencies, and the fourth transition display frame Tg4 and the first frame Tp1 (or Tpn) in the brightness adjustment mode to be switched are both greater than the preset refresh frequency. The display refresh frequency of the fourth transition display frame Tg4 can be greater than the preset refresh frequency, and the display luminous duty cycle of the fourth transition display frame Tg4 is between the first display luminous duty cycle and the second display luminous duty cycle, so that the difference between the display luminous duty cycle of the fourth transition display frame Tg4 and the first transition display frame Tg1 is small, and the display luminous duty cycle of the fourth transition display frame Tg4 and the first frame picture Tp1 (or Td1) of the brightness adjustment mode to be switched also has a small difference, so that the first transition display frame Tg1 and the fourth transition display frame Tg4 have a small display brightness difference, and the fourth transition display frame Tg4 and the first frame picture Tp1 (or Td1) of the brightness adjustment mode to be switched have a small display brightness difference, so that the first transition display frame Tg1 can smoothly transition to the fourth transition display frame Tg4, and the fourth transition display frame Tg4 can smoothly transition to the first frame picture Tp1 (or Td1) of the brightness adjustment mode to be switched, thereby improving the screen flicker problem, improving the display uniformity of the display panel, and improving the display effect of the display panel.

[0121] In addition, two transition display frames are inserted between the last frame Tdn (or Tpn) in the current brightness adjustment mode and the first frame Tp1 (or Td1) in the brightness adjustment mode to be switched, namely, a first transition display frame Tg1 and a fourth transition display frame Tg4, so that the transition display frame has a shorter display time, thereby being able to quickly switch from the last frame Tdn (or Tpn) in the current brightness adjustment mode to the first frame Tp1 (or Td1) in the brightness adjustment mode to be switched, which is beneficial to improving the display effect of the display panel.

[0122] Optionally, the brightness adjustment mode of the first transition display frame Tg1 is the current brightness adjustment mode; and the brightness adjustment mode of the fourth transition display frame Tg4 is the brightness adjustment mode to be switched.

[0123] For details, please refer to Fig.23 and Fig.24 In any of the accompanying drawings, when the current brightness adjustment mode is the DC mode, the brightness adjustment mode of the first transition display frame Tg1 is also the DC mode; and when the current brightness adjustment mode is the PWM mode, the brightness adjustment mode of the first transition display frame Tg1 is also the PWM mode, so that when the last frame Tdn (or Tpn) under the current brightness adjustment mode is switched to the first transition display frame Tg1, there is no need to switch the current brightness adjustment mode, which can simplify the driving method of the display panel. Correspondingly, when the brightness adjustment mode to be switched is the PWM mode, the brightness adjustment mode of the fourth transition display frame Tg4 is also the PWM mode; and when the brightness adjustment mode to be switched is the DC mode, the brightness adjustment mode of the fourth transition display frame Tg4 is also the DC mode, so that when the last frame Tp1 (or Td1) under the brightness adjustment mode to be switched is switched to the fourth transition display frame Tg4, there is no need to switch the current brightness adjustment mode, which can simplify the driving method of the display panel.

[0124] Optionally, when the first display luminous duty cycle is A, the second display luminous duty cycle is B, and the display luminous duty cycle of the fourth transition display frame is C, the difference between |AC| and |BC| is within a preset duty cycle difference range.

[0125] Among them, the preset duty cycle difference range can be understood as a smaller difference range. For example, the upper limit of the preset duty cycle difference range can be less than or equal to 30%, and the lower limit of the preset duty cycle difference range can be greater than or equal to 0. It can be designed according to actual needs, and the embodiment of the present invention does not make specific limitations on this. It can be understood that when the display luminous duty cycle of two adjacent frames is within the preset duty cycle difference range, the display brightness difference caused by the difference in the display luminous duty cycle of the two frames is small.

[0126] For details, please refer to Fig.23 and Fig.24In any of the accompanying drawings, since the display luminous duty cycle of the first transition display frame Tg1 is the first display luminous duty cycle A, the display luminous duty cycle of the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched is the first display luminous duty cycle B, and the display luminous duty cycle of the fourth transition display frame Tg4 is C, the difference between the display luminous duty cycles of the first transition display frame Tg1 and the fourth transition display frame Tg4 is AC, the difference between the display luminous duty cycles of the first frame picture Tp1 (or Td1) and the fourth transition display frame Tg4 in the brightness adjustment mode to be switched is BC, and when the difference between |AC| and |BC| is within the preset duty cycle difference range Due to the difference in display luminous duty, the display brightness difference between the first transition display frame Tg1 and the fourth transition display frame Tg4 is smaller, and the display brightness difference between the fourth transition display frame Tg4 and the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched is smaller, so that when switching from the first transition display frame Tg1 to the fourth transition display frame Tg4, there can be a smaller display brightness change, and when switching from the fourth transition display frame Tg4 to the first frame picture Tp1 (or Td1) in the brightness adjustment mode to be switched, there can also be a smaller display brightness change, which is beneficial to improve the screen flickering problem and improve the display effect of the display panel.

[0127] It should be noted that the above description only exemplifies the situation in which two transition display frames can be inserted in the brightness switching process when the current display refresh frequency is greater than the preset refresh frequency. In the embodiment of the present invention, the two transition display frames inserted in the brightness switching transition are not limited to the above situation and can be designed according to actual needs. The embodiment of the present invention does not make specific limitations on this.

[0128] For example, Fig.25 and Fig.26In any of the accompanying drawings, the two transition display frames inserted in the brightness switching transition may also be the fifth transition display frame Tg5 and the second transition display frame Tg2, respectively. The display luminous duty cycle of the fifth transition display frame Tg5 may be between the first display luminous duty cycle and the second display luminous duty cycle, and the fifth transition display frame Tg5 may be between the last frame Tdn (or Tpn) in the current brightness switching mode and the second transition display frame Tg2. In this way, a smaller display brightness difference can be made between the last frame Tdn (or Tpn) in the current brightness switching mode and the fifth transition display frame Tg5, and a smaller display brightness difference can be made between the fifth transition display frame Tg5 and the second transition display frame Tg2. Therefore, when the last frame Tdn (or Tpn) in the current brightness switching mode is switched to the fifth transition display frame Tg5, a smaller display brightness change can be made, and when the fifth transition display frame Tg5 is switched to the second transition display frame Tg2, a smaller display brightness change can be made, which is beneficial to improve the screen flickering problem and improve the display effect of the display panel.

[0129] Based on the same inventive concept, an embodiment of the present invention also provides a display control device for a display panel, which can improve the screen flicker problem of the display panel. The display control device for the display panel of the embodiment of the present invention can execute the display control method for the display panel provided by the embodiment of the present invention to control the display panel provided by the embodiment of the present invention to display a picture. The display control device for the display panel can be implemented by software and / or hardware, and the display control device for the display panel can be integrated in a driver chip for driving the display panel.
