For example, without departing from the scope of the embodiments of this application, the first direction may also be referred to as the second direction, and similarly, the second direction may also be referred to as the first direction.

[0044] Through careful and in-depth research, the applicant of this case has provided a solution to the problems existing in the prior art.

[0045] Figure 1 Schematic diagram of a display module provided for the embodiments of this application.

[0046] The embodiments of this application provide a display module 100, as Figure 1 shown, the display module 100 includes a display panel 001, and the display panel 001 includes a plurality of sub-pixels 01, and the plurality of sub-pixels 01 include a first sub-pixel 11 and a second sub-pixel 12.

[0047] In the same frame display image of the display panel 001, the data writing frequency of the first sub-pixel 11 is the first frequency, and the data writing frequency of the second sub-pixel 12 is the second frequency. Among them, one of the first frequency and the second frequency is greater than the other.

[0048] That is to say, in the same frame display image of the display panel 001, the first sub-pixel 11 and the second sub-pixel 12 receive data signals at different frequencies.

[0049] It should be noted that in one frame display image of the display panel 001, the sub-pixel with the lower data writing frequency among the first sub-pixel 11 and the second sub-pixel 12 may write the data signal only once.

[0050] With the development of display technology, different regions of the display panel 001 often undertake different functions, and different sub-pixels 01 undertake different display requirements. In the embodiments of the present application, the first sub-pixel 11 and the second sub-pixel 12 adopt different designs, and the frequencies at which the first sub-pixel 11 and the second sub-pixel 12 receive data signals are set differently, which is conducive to realizing fine control of the first sub-pixel 11 and the second sub-pixel 12. Thus, when driving the display panel 001 to emit light, the display characteristics of the first sub-pixel 11 and the second sub-pixel 12 can be taken into account, the luminous efficiency of the first sub-pixel 11 and the second sub-pixel 12 can be improved, and further the display quality of the display panel 001 can be improved.

[0051] In addition, realizing fine control of the first sub-pixel 11 and the second sub-pixel 12 can also save power consumption and reduce usage costs.

[0052] Figure 2 Schematic diagram for providing data signals for a first type of driving chip related to the present application Figure 3 Schematic diagram for providing data signals for a second type of driving chip related to the present application.

[0053] Please continue to refer to Figure 1 , in an embodiment of the present application, the display module 100 further includes a first type of driving chip PA and a second type of driving chip PB. Among them, the first type of driving chip PA is used to provide a data signal with a first frequency to the first sub-pixel 11, and the second type of driving chip PB is used to provide a data signal with a second frequency to the second sub-pixel 12.

[0054] Specifically, in combination with Figure 1 and Figure 2 as shown, the first sub-pixel 11 includes a first pixel circuit 111 and a first light-emitting element 112. The display module 100 includes a first data line DL1, the first data line DL1 is electrically connected to the first type of driving chip PA and the first pixel circuit 111, and the first type of driving chip PA transmits a data signal Vdata with a first frequency to the first pixel circuit 111 through the first data line DL1.

[0055] In combination with Figure 1 and Figure 3 as shown, the second sub-pixel 12 includes a second pixel circuit 121 and a second light-emitting element 122. The display module 100 includes a second data line DL2, the second data line DL2 is electrically connected to the second type of driving chip PB and the second pixel circuit 121, and the second type of driving chip PB transmits a data signal Vdata with a second frequency to the second pixel circuit 121 through the second data line DL2.

[0056] Optionally, the first pixel circuit 111 is a pixel circuit driven by Pulse Amplitude Modulation (PAM), and the second pixel circuit 121 is a pixel circuit driven by Pulse Width Modulation (PWM) and PAM.

[0057] In the embodiments of the present application, setting the first type of driving chip PA and the second type of driving chip PB to provide data signals with different frequencies to the first sub-pixel 11 and the second sub-pixel 12 respectively is beneficial to reducing the design difficulty of providing data signals with different frequencies and simplifying the manufacturing difficulty of the display module 100.

[0058] In an embodiment of the present application, the light-emitting color of the first sub-pixel 11 includes red and / or green, and the light-emitting color of the second sub-pixel 12 is blue. That is, in the display panel 001, the first sub-pixel 11 may only include red sub-pixels, may only include green sub-pixels, or may include both red sub-pixels and green sub-pixels; the second sub-pixel 12 may be a blue sub-pixel.

[0059] Optionally, the first sub-pixel 11 includes Quantum Dot Light Emitting Diodes (QD-LEDs), and the second sub-pixel 12 includes Micro Light Emitting Diodes (Micro-LEDs).

[0060] That is to say, the first light-emitting element 112 included in the first sub-pixel 11 may be a QD-LED, and the QD-LED may emit red light or green light. The second light-emitting element 122 included in the second sub-pixel 12 may be a Micro-LED, and the Micro-LED may emit blue light.

[0061] It should be noted that in some other embodiments, the first sub-pixel 11 may further include an Organic Light Emitting Diode (OLED).

[0062] In the related art, Micro-LEDs have the advantages of low power consumption, high brightness, high color saturation, high response speed, and long lifespan. However, there are certain display problems with the red or green light emitted by Micro-LEDs.

[0063] Specifically, the efficiency of Micro-LEDs in emitting red light is relatively low, and during operation, as the temperature increases, its luminous efficiency will drop sharply. The green light emitted by Micro-LEDs will have an offset of the light peak position at low brightness, which is likely to cause color deviation in the display panel.

[0064] At present, the use of QD-LED can solve the problems of red and green light in Micro-LED. Moreover, due to the characteristics of the inorganic light-emitting layer of QD-LED itself, its working life is even higher than that of Organic Light Emitting Diode (OLED). However, the life of QD-LED used to emit blue light is shorter.

[0065] Therefore, in the embodiment of the present application, the first sub-pixel 11 is set to emit red light and / or green light, and the second sub-pixel 12 is set to emit blue light. The combination of QD-LED and Micro-LED for display is beneficial to improving the display effect and service life of the display panel 001.

[0066] At the same time, the driving methods matching the display characteristics of the first sub-pixel 11 and the second sub-pixel 12 respectively are beneficial to making the luminous efficiencies of the first sub-pixel 11 and the second sub-pixel 12 reach the best state, and further improving the display quality.

[0067] In an embodiment of the present application, in the same frame display screen of the display panel 001, the second frequency is greater than the first frequency. That is, the data writing frequency of the second sub-pixel 12 is greater than the data writing frequency of the first sub-pixel 11.

[0068] As can be seen from the above analysis, the first sub-pixel 11 may include QD-LED, and the second sub-pixel 12 may include Micro-LED. The display characteristics of Micro-LED are related to its driving frequency. When the driving frequency of Micro-LED is relatively high, its luminous efficiency is relatively high; while QD-LED does not require high-frequency driving, and its luminous efficiency can reach a relatively high level.

[0069] Therefore, in the embodiment of the present application, the data writing frequency of the second sub-pixel 12 is set to be greater than the data writing frequency of the first sub-pixel 11, and the driving methods matching the display characteristics of the first sub-pixel 11 and the second sub-pixel 12 respectively are beneficial to making the luminous efficiencies of the first sub-pixel 11 and the second sub-pixel 12 reach the best state, and improving the display quality.

[0070] Figure 4 It is a schematic diagram of another display module provided by the embodiment of the present application.

[0071] As Figure 4 shown, in an embodiment of the present application, the light-emitting area of the second sub-pixel 12 is greater than the light-emitting area of the first sub-pixel 11. That is, the Micro-LED in the second sub-pixel 12 can be set larger relative to the QD-LED in the first sub-pixel 11.

[0072] According to the light-emitting characteristics of Micro-LED and QD-LED, the light-emitting efficiency of the first sub-pixel 11 is greater than that of the second sub-pixel 12. Therefore, in the embodiments of the present application, the light-emitting area of the second sub-pixel 12 is set to be relatively large, which is beneficial to further improving the light-emitting efficiency of the second sub-pixel 12, making the light-emitting efficiencies of the first sub-pixel 11 and the second sub-pixel 12 tend to be consistent, thereby further improving the display effect of the display panel 001.

[0073] Figure 5 As Figure 2 shown in a timing diagram of the first pixel circuit, Figure 6 As Figure 3 shown in a timing diagram of the second pixel circuit.

[0074] In an embodiment of the present application, in a frame of display image of the display panel 001, the first pixel circuit 111 in the first sub-pixel 11 may receive a data signal only once, and the second pixel circuit 121 in the second sub-pixel 12 may receive the data signal multiple times.

[0075] Combined with Figure 5 and Figure 6 shown, in a frame of display image F1 of the display panel 001, the sub-pixel 01 may include multiple light-emitting stages t3. Among them, in the same frame of display image F1 of the display panel 001, the durations of different light-emitting stages t3 of the first sub-pixel 11 are the same, and the durations of at least some different light-emitting stages t3 of the second sub-pixel 12 are different.

[0076] It should be noted that Figure 5 and Figure 6 only show the case where a frame of display image F1 includes three light-emitting stages t3. In some other embodiments, a frame of display image F1 may also include other numbers of light-emitting stages t3.

[0077] In the embodiments of the present application, the first sub-pixel 11 receives a data signal once in a frame of display image, and the durations of different light-emitting stages t3 in a frame of display image are the same, so its brightness in different light-emitting stages t3 is the same, which is beneficial to reducing the flicker of the first sub-pixel 11 and improving the display quality of the first sub-pixel 11.

[0078] The second sub-pixel 12 can receive data signals multiple times in a frame of display screen. Thus, the Micro-LEDs included therein can receive different driving currents at least in some different light-emitting stages t3 in a frame of display screen, which is beneficial to improving the light-emitting efficiency of the Micro-LEDs, that is, improving the light-emitting efficiency of the second sub-pixel 12. In addition, by setting the durations of at least some different light-emitting stages t3 of the second sub-pixel 12 in a frame of display screen F1 to be different, it is beneficial to flexibly adjust the light-emitting brightness in different light-emitting stages t3 to meet the display requirements in different situations.

[0079] To more clearly illustrate the technical solution of the embodiments of the present application, the following combines Figure 2 and Figure 5 to describe Figure 2 the working process of the first pixel circuit shown as follows:

[0080] As Figure 2 shown, the first pixel circuit 111 includes a driving transistor Md for providing a driving current to the first light-emitting element 112. In addition, the first pixel circuit 111 further includes a first transistor M1, a second transistor M2, a third transistor M3, a fourth transistor M4, a fifth transistor M5, and a sixth transistor M6.

[0081] Among them, the source of the first transistor M1 is electrically connected to the reset signal line SL1, the drain is electrically connected to the gate of the driving transistor Md, and the gate is electrically connected to the first scan line S1; the source of the second transistor M2 is electrically connected to the first data line DL1, the drain is electrically connected to the source of the driving transistor Md, and the gate is electrically connected to the second scan line S2; the source of the third transistor M3 is electrically connected to the drain of the driving transistor Md, the drain is electrically connected to the gate of the driving transistor Md, and the gate is electrically connected to the second scan line S2; the source of the fourth transistor M4 is electrically connected to the power supply voltage signal line DY1, the drain is electrically connected to the source of the driving transistor Md, and the gate is electrically connected to the light-emitting control signal line EM; the source of the fifth transistor M5 is electrically connected to the drain of the driving transistor Md, the drain is electrically connected to the first pole of the first light-emitting element 112, and the gate is electrically connected to the light-emitting control signal line EM; the source of the sixth transistor M6 is electrically connected to the reset signal line SL1, the drain is electrically connected to the first pole of the first light-emitting element 112, and the gate is electrically connected to the first scan line S1.

[0082] It should be noted that the following takes the first transistor M1, the second transistor M2, the third transistor M3, the fourth transistor M4, the fifth transistor M5, and the sixth transistor M6 as P-type transistors as an example for description.

[0083] In a frame of display screen of the display panel 001, the working process of the first pixel circuit 111 includes a reset stage t1, a data writing stage t2, and a light-emitting stage t3.

[0084] In the reset stage t1, the first scan line S1 transmits an enable signal, i.e., a low-level signal, and the first transistor M1 and the sixth transistor M6 are turned on; the second scan line S2 and the emission control signal line EM transmit a disable signal, i.e., a high-level signal, and the second transistor M2, the third transistor M3, the fourth transistor M4, and the fifth transistor M5 are turned off. At the same time, the reset signal line SL1 transmits a reset voltage Vref, and the reset voltage Vref is transmitted to the gate of the driving transistor Td through the turned-on first transistor M1, completing the reset of the gate of the driving transistor Md. The reset voltage Vref resets the first pole of the first light-emitting element 112 through the turned-on sixth transistor M6. Optionally, the first light-emitting element 112 is a quantum dot light-emitting diode, and the reset voltage Vref resets the anode of the quantum dot light-emitting diode through the turned-on sixth transistor M6.

[0085] In the data writing stage t2, the second scan line S2 transmits an enable signal, i.e., a low-level signal, and the second transistor M2 and the third transistor M3 are turned on; the first scan line S1 and the emission control signal line EM transmit a disable signal, i.e., a high-level signal, and the first transistor M1, the fourth transistor M4, the fifth transistor M5, and the sixth transistor M6 are turned off. At the same time, the first type of driving chip PA transmits a data voltage Vdata to the first data line DL1. At the starting point of the data writing stage t2, the gate potential of the driving transistor Md is the reset voltage Vref, the source potential of the driving transistor Md is the data voltage Vdata, and the potential difference between the source and the gate of the driving transistor Md is (Vdata - Vref). Since the potential difference between the two is greater than 0, the driving transistor Md is turned on, and the data voltage Vdata is transmitted to the gate of the driving transistor Md through the turned-on driving transistor Md and the turned-on third transistor M3, causing the gate potential of the driving transistor Md to gradually increase. When the gate potential of the driving transistor Md is equal to (Vdata - |Vth|), the driving transistor Md is turned off. Here, Vth is the threshold voltage of the driving transistor Md.

[0086] In the emission stage t3, the first scan line S1 and the second scan line S2 transmit a disable signal, i.e., a high-level signal, and the first transistor M1, the second transistor M2, the third transistor M3, and the sixth transistor M6 are turned off; the emission control signal line EM transmits an enable signal, i.e., a low-level signal, and the fourth transistor M4 and the fifth transistor M5 are turned on. At the same time, the power supply voltage signal line DY1 transmits a power supply voltage VDD, i.e., the potential of the source of the driving transistor Md is the power supply voltage VDD. Since the potential of the power supply voltage VDD is greater than the potential of the data voltage Vdata, the driving transistor Md generates a driving current and transmits it to the first light-emitting element 112 through the fifth transistor M5, controlling the first light-emitting element 112 to emit light.

[0087] Figure 3 The difference between the second pixel circuit 121 shown and Figure 2 the first pixel circuit shown is that: the source of the second transistor M2 in the second pixel circuit 121 is electrically connected to the second data line DL2, and in the data writing stage t2, the second pixel circuit 121 receives the data voltage Vdata transmitted by the second type of driving chip PB to it.

[0088] In one frame of the display screen of the display panel 001, as Figure 5 shown, the first pixel circuit 111 can execute multiple light emitting stages t3. The first pixel circuit 111 only performs a data writing stage t2 once before the first light emitting stage t3, that is, the first sub-pixel 11 only receives a data signal once in one frame of the display screen. The first pixel circuit 111 can be a pixel circuit driven by PAM. As Figure 6 shown, the second pixel circuit 121 can execute the same number of light emitting stages t3 as the first pixel circuit 111. Before each light emitting stage t3, the second pixel circuit 121 performs a reset stage t1 and a data writing stage t2 once, and in different data writing stages t2, the data voltage Vdata transmitted by the second type of driving chip PB can be different. The second pixel circuit 121 can be a pixel circuit jointly driven by PAM and PWM.

[0089] It should be noted that the embodiments of the present application only give examples where the structures of the first pixel circuit 111 and the second pixel circuit 121 are the same. In some other embodiments, the structure of the second pixel circuit 121 can be different from that of the first pixel circuit 111, and the second pixel circuit 121 can include more transistors relative to the first pixel circuit 111.

[0090] Figure 7 This is a control diagram of the light emitting stages of the first sub-pixel and the second sub-pixel provided by the embodiments of the present application, Figure 8 This is another control diagram of the light emitting stages of the first sub-pixel and the second sub-pixel provided by the embodiments of the present application, Figure 9 This is another control diagram of the light emitting stages of the first sub-pixel and the second sub-pixel provided by the embodiments of the present application, Figure 10 This is another control diagram of the light emitting stages of the first sub-pixel and the second sub-pixel provided by the embodiments of the present application.

[0091] In an embodiment of the present application, as Figures 7 - 10As shown, in the same frame display screen F1 of the display panel 001, the light-emitting stage t3 of the first sub-pixel 11 overlaps with the light-emitting stage t3 of the second sub-pixel 12. That is, the time period during which the light-emitting control signal line EM transmits an enable signal (such as a low-level signal) in the first sub-pixel 11 overlaps with the time period during which the light-emitting control signal line EM transmits an enable signal (such as a low-level signal) in the second sub-pixel 12.

[0092] Optionally, as Figure 7 shown, in the same frame display screen F1 of the display panel 001, the light-emitting stage t3 of the first sub-pixel 11 covers the light-emitting stage t3 of the second sub-pixel 12.
