Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and driving method, and a display device. Background Technology

[0002] When LEDs are small, such as at the nanometer level, accurately transferring millions or even tens of millions of LEDs is one of the core challenges in display panel manufacturing.

[0003] Current transfer technologies include vacuum or magnetic pickup, laser transfer, and self-assembly. In self-assembly, LEDs are suspended on a liquid template and formed into an ordered array by an electric field. Improper control of the electric field direction or intensity can cause the LEDs to reverse direction during the arrangement process. In current micro-LED displays, the pixel circuits only provide unidirectional current, driving LEDs in only one direction, resulting in approximately half of the LEDs' lifespan remaining unused.

[0004] Therefore, how to improve the efficiency of light-emitting elements, extend the effective working life of pixels, and delay brightness decay has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the aforementioned technical problems, this disclosure provides a display panel, driving method, and display device to improve the efficiency of light-emitting elements, extend the effective working life of pixels, and delay brightness decay.

[0006] In a first aspect, the present invention provides a display panel comprising: a plurality of sub-pixels; each sub-pixel includes a pixel circuit and a light-emitting control module, wherein a first input terminal of the light-emitting control module is connected to the output terminal of the pixel circuit, and a second input terminal of the light-emitting control module is connected to a first common voltage signal line; The light emission control module includes multiple switching elements and at least two anti-parallel light emission elements. During the display time of one frame on the display panel, the switching elements are used to control the light emission elements to emit light respectively.

[0007] Based on the same inventive concept, this disclosure provides a driving method for a display panel, used to drive the display panel as described above, including: The display time of one frame on the display panel includes a first time period and a second time period; During the first time period, the light-emitting control module controls the first light-emitting element to emit light, and during the second time period, the light-emitting control module controls the second light-emitting element to emit light.

[0008] Based on the same inventive concept, this disclosure provides a display device, including the display panel as described above.

[0009] The technical solution provided in this disclosure has the following advantages compared with the prior art: The present invention provides a display panel, driving method, and display device, comprising: a plurality of sub-pixels; each sub-pixel includes a pixel circuit and a light-emitting control module, wherein a first input terminal of the light-emitting control module is connected to the output terminal of the pixel circuit, and a second input terminal of the light-emitting control module is connected to a first common voltage signal line; the light-emitting control module includes a plurality of switching elements and at least two anti-parallel light-emitting elements, wherein during the display time of one frame of the display panel, the switching elements are used to control the light-emitting elements to emit light separately. By designing a light-emitting control module including anti-parallel switching elements, through precise timing control of the switching elements, the anti-parallel light-emitting elements can be selectively turned on during the display time of one frame of the display panel, so that the anti-parallel light-emitting elements emit light separately. In this way, the anti-parallel light-emitting elements in the same sub-pixel emit light in a time-division manner during the display time of one frame, which can effectively improve the utilization efficiency of the light-emitting elements, extend the effective working life of the pixel, and delay brightness decay.

Detailed Implementation

[0013] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0014] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0015] In the liquid-phase transfer process, LEDs are suspended on a liquid template and formed into an ordered array by electric field. If the direction or intensity of the electric field is not properly controlled, the LEDs may reverse direction during the arrangement process. In current micro LED displays, the pixel circuits only provide unidirectional current, driving LEDs in only one direction, meaning approximately half of the LEDs' lifespan is not utilized.

[0016] To address the aforementioned issues, this disclosure provides a display panel, driving method, and display device to improve the efficiency of light-emitting elements, extend the effective working life of pixels, and delay brightness decay.

[0017] Figure 1 The figure shown is a plan view of a display panel provided in an embodiment of this disclosure. Figure 2 As shown Figure 1 Please refer to the circuit connection diagram of a neutron pixel. Figure 1 and Figure 2 This disclosure provides a display panel 100, which can be a micro LED display panel, mini LED display panel, etc. The LED panel, by mixing different colored LED light sources, can produce various colors with extremely high precision, exhibiting strong color reproduction capabilities, high contrast, and rich brightness and detail in the displayed image. The above is merely an example; other types of display panels are also possible, and this disclosure does not limit the scope of the application.

[0018] Display panel 100 includes multiple sub-pixels P, Figure 1 This illustration only shows the arrangement of sub-pixels P, without limiting the shape and size of sub-pixels P. Sub-pixels P include pixel circuit 10 and light-emitting control module 20. Pixel circuit 10 is used to drive the light-emitting element L in light-emitting control module 20 to emit light. Optionally, the light-emitting element L includes red light-emitting element, blue light-emitting element, green light-emitting element, etc., and this disclosure does not limit the type of light-emitting element L. The first input terminal 21 of light-emitting control module 20 is connected to the output terminal 11 of pixel circuit 10, and the second input terminal 22 of light-emitting control module 20 is connected to the first common voltage signal line Y1. Light-emitting control module 20 includes multiple switching elements K and at least two anti-parallel light-emitting elements L. During the display time of one frame of the display panel 100, the switching elements K are used to control the light-emitting elements L to emit light respectively.

[0019] Specifically, the sub-pixel P includes a pixel circuit 10 and a light-emitting control module 20. The light-emitting control module 20 includes two input terminals: a first input terminal 21 for receiving the output signal from the pixel circuit 10, and a second input terminal 22 for receiving a first common voltage signal VEE. The light-emitting control module 20 includes a switching element K and at least two anti-parallel light-emitting elements L. During the display time of one frame on the display panel 100, the anti-parallel light-emitting elements L in the light-emitting control module 20 emit light respectively. That is, by turning on or off different switching elements K in the light-emitting control module 20, and by precisely controlling the timing of the light emission, the anti-parallel light-emitting elements L in the light-emitting control module 20 can be controlled to emit light separately, allowing the sub-pixel to emit light within the display time of one frame by utilizing the lifespan of different light-emitting elements L.

[0020] Compared to related technologies, where pixel circuits only provide unidirectional current and can only drive light-emitting elements in one direction, at least a portion of the LED's lifespan remains unused. The optimized driving circuit of this disclosure, even in cases where LEDs transferred via liquid phase are inverted, can drive both forward-facing LEDs and LEDs with reversed cathodes and anodes to emit light, effectively improving the utilization efficiency of the light-emitting element L, extending the effective lifespan of the pixel, and delaying brightness decay.

[0021] Thus, by configuring the light-emitting control module 20 to include multiple switching elements K and at least two anti-parallel light-emitting elements L, it is possible to enable the switching elements K to control the light-emitting elements L to emit light separately during the display time of one frame of the display panel 100. This can improve the utilization rate of the light-emitting elements L caused by the liquid phase method of LED inversion, extend the effective working life of the pixels, and delay the brightness decay.

[0022] Please refer to Figure 2 In a display panel 100 provided in this disclosure, the light-emitting element L includes a first light-emitting element L1 and a second light-emitting element L2. The first light-emitting element L1 and the second light-emitting element L2 are connected in parallel. The positive electrode of the first light-emitting element L1 and the negative electrode of the second light-emitting element L2 are connected to a first node N1, and the negative electrode of the first light-emitting element L1 and the positive electrode of the second light-emitting element L2 are connected to a second node N2. At least a portion of the switching elements K are connected between the first node N1 and the output terminal 11 of the pixel circuit 10, and at least a portion of the switching elements K are connected between the second node N2 and the output terminal 11 of the pixel circuit 10.

[0023] Specifically, the anti-parallel light-emitting elements L need to be in a forward bias state at specific times to emit light independently. By controlling the opening and closing timing of the switching element K connected between the first node N1 and the output terminal 11 of the pixel circuit 10, and by controlling the opening and closing timing of the switching element K connected between the second node N2 and the output terminal 11 of the pixel circuit 10, it is possible to control whether the output current of the pixel circuit 10 flows through the first light-emitting element L1 or the second light-emitting element L2, so as to realize that the two anti-parallel light-emitting elements L emit light in a time-sharing and alternating manner. For example, when the switching element K connected between the first node N1 and the output terminal 11 of the pixel circuit 10 is turned on, the output current of the pixel circuit 10 flows from the turned-on switching element K, through the first node N1, and through the positive terminal of the first light-emitting element L1 connected to the first node N1, controlling the first light-emitting element L1 to emit light. When the switching element K connected between the second node N2 and the output terminal 11 of the pixel circuit 10 is turned on, the output current of the pixel circuit 10 flows from the turned-on switching element K through the second node N2 and through the positive terminal of the second light-emitting element L2 connected to the second node N2, thereby controlling the second light-emitting element L2 to emit light.

[0024] Thus, by connecting at least some of the switching elements K between the first node N1 and the output terminal 11 of the pixel circuit 10, and connecting at least some of the switching elements K between the second node N2 and the output terminal 11 of the pixel circuit 10, the output current of the pixel circuit 10 can be controlled to flow to the positive terminal of the first light-emitting element L1 or the positive terminal of the second light-emitting element L2 at a specific time, thereby realizing that the first light-emitting element L1 and the second light-emitting element L2 connected in reverse parallel emit light respectively within the display time of one frame, so as to improve the service life of the light-emitting element L.

[0025] Please continue to refer to this. Figure 2 In a display panel 100 provided in this disclosure, the switching element K includes a first switching element K1 and a second switching element K2. The first switching element K1 is connected between the output terminal 11 of the pixel circuit 10 and the first node N1, and the second switching element K2 is connected between the output terminal 11 of the pixel circuit 10 and the second node N2. The display panel 100 includes a first light emission control signal line F1 and a second light emission control signal line F2. The first light emission control signal line F1 is connected to the control terminal of the first switching element K1, and the second light emission control signal line F2 is connected to the control terminal of the second switching element K2. The first switching element K1 and the second switching element K2 are time-divisionally turned on.

[0026] Specifically, the first light-emitting control signal line F1 is connected to the control terminal of the first switching element K1, and the second light-emitting control signal line F2 is connected to the control terminal of the second switching element K2. The on / off timing of the first and second switching elements K1 and K2 can be independently controlled without interference. The first light-emitting element L1 and the second light-emitting element L2 are connected in reverse parallel. When the first light-emitting control signal line F1 controls the first switching element K1 to conduct, the output current of the pixel circuit 10 flows through the first node N1 to the first light-emitting element L1; when the second light-emitting control signal line F2 controls the second switching element K2 to conduct, the output current of the pixel circuit 10 flows through the second node N2 to the second light-emitting element L2. That is, by setting independent switch control signal lines for the first and second switching elements K1 and K2 respectively, the first and second switching elements K1 and K2 can be controlled to conduct in a time-division manner, so that the reverse-parallel light-emitting elements L emit light separately within one frame display time. The alternating emission of the first and second light-emitting elements L1 and L2 can balance the usage frequency of the two light-emitting elements L, improve the utilization rate of the light-emitting elements L, and thus extend the equivalent lifespan of the entire pixel.

[0027] Thus, by connecting the first light-emitting control signal line F1 to the control terminal of the first switching element K1 and the second light-emitting control signal line F2 to the control terminal of the second switching element K2, the first switching element K1 and the second switching element K2 are time-divisionally turned on. The first switching element K1 connected to the first node N1 and the second switching element K2 connected to the second node N2 can be independently controlled. Within the display time of one frame, the opening and closing timing of the first switching element K1 and the second switching element K2 do not interfere with each other. This enables the time-divisionally controllable light emission of the anti-parallel light-emitting elements L, balances the usage frequency of different light-emitting elements L, and improves the equivalent lifespan of the sub-pixel P.

[0028] Figure 3 As shown Figure 1 Please refer to another circuit connection diagram for neutron pixels. Figure 3In a display panel 100 provided in this disclosure, the switching element K includes a third switching element K3 and a fourth switching element K4. The third switching element K3 is connected between the first node N1 and the first common voltage signal line Y1; the fourth switching element K4 is connected between the second node N2 and the first common voltage signal line Y1.

[0029] In one optional embodiment provided in this disclosure, the first input terminal 21 of the light-emitting control module 20 is connected to the output terminal 11 of the pixel circuit 10, and the second input terminal 22 of the light-emitting control module 20 is connected to the first common voltage signal line Y1. The light-emitting control module 20 includes a first switching element K1 connected to the first node N1 and the output terminal 11 of the pixel circuit 10, a second switching element K2 connected to the second node N2 and the output terminal 11 of the pixel circuit 10, a first light-emitting control signal line F1 connected to the control terminal of the first switching element K1, and a second light-emitting control signal line F2 connected to the control terminal of the second switching element K2; and a first light-emitting element L1 and a second light-emitting element L2 connected in reverse parallel, the positive terminal of the first light-emitting element L1 and the negative terminal of the second light-emitting element L2 connected to the first node N1, and the positive terminal of the second light-emitting element L2 and the negative terminal of the first light-emitting element L1 connected to the second node N2. A third switching element K3 is connected between the first node N1 and the first common voltage signal line Y1, and a fourth switching element K4 is connected between the second node N2 and the first common voltage signal line Y1. That is, the first common voltage signal line Y1 is connected to the first node N1 through the third switching element K3. Furthermore, the first common voltage signal line Y1 is connected to the negative terminal of the second light-emitting element L2 through the third switching element K3. The first common voltage signal line Y1 is connected to the second node N2 through the fourth switching element K4. Furthermore, the first common voltage signal line Y1 is connected to the negative terminal of the first light-emitting element L1 through the fourth switching element K4.

[0030] When the first light-emitting element L1 needs to be driven to emit light, the first light-emitting control signal line F1 controls the first switching element K1 to conduct. The output current of the pixel circuit 10 returns to the first common voltage signal line Y1 through the first switching element K1, the first light-emitting element L1, and the fourth switching element K4. When the second light-emitting element L2 needs to be driven to emit light, the second light-emitting control signal line F2 controls the second switching element K2 to conduct. The output current of the pixel circuit 10 returns to the first common voltage signal line Y1 through the second switching element K2, the second light-emitting element L2, and the third switching element K3, thus forming a complete current loop for the first light-emitting element L1 and the second light-emitting element L2. That is, when the first switching element K1 and the fourth switching element K4 are simultaneously conducted, or when the second switching element K2 and the third switching element K3 are simultaneously conducted, the corresponding light-emitting element L can form a loop and emit light, which is beneficial for independent control of the light-emitting period.

[0031] Thus, by connecting the third switching element K3 between the first node N1 and the first common voltage signal line Y1, and the fourth switching element K4 between the second node N2 and the first common voltage signal line Y1, different light-emitting elements L in the same sub-pixel P are simultaneously controlled by two sets of switching elements K, which is beneficial for achieving time-division emissivity of the anti-parallel light-emitting elements L. Furthermore, both the third switching element K3 and the fourth switching element K4 are connected to the first common voltage signal line Y1, reducing wiring complexity and facilitating the integration of the high-resolution display panel 100. Further, when all switching elements K in the sub-pixel P are turned off, the light-emitting element L is physically isolated from the output terminal 11 of the pixel circuit 10 and the first common voltage signal line Y1. This helps prevent the light-emitting element L from being interfered with by unnecessary parasitic currents or noise during write, store, or reset operations of the pixel circuit 10, improving the stability and reliability of the pixel.

[0032] Please continue to refer to this. Figure 3 In a display panel 100 provided in this disclosure, the control terminals of the second switching element K2 and the third switching element K3 are connected to the same second light emission control signal line F2, and the control terminals of the first switching element K1 and the fourth switching element K4 are connected to the same first light emission control signal line F1; the second switching element K2 and the third switching element K3 are transistors of the same type, and the first switching element K1 and the fourth switching element K4 are transistors of the same type.

[0033] In traditional circuit design, one control line typically controls one switching element K. In high-resolution display panels, wiring occupies a significant amount of pixel space. In this embodiment, the second light-emitting control signal line F2 simultaneously controls the second switching element K2 and the third switching element K3, and the first light-emitting control signal line F1 simultaneously controls the first switching element K1 and the fourth switching element K4. Precise timing control of four switching elements K can be achieved with only two control lines. By reducing the number of control lines in each light-emitting control module 20 from four to two, wiring can be simplified, and pixel space occupancy can be reduced.

[0034] When the first light-emitting element L1 needs to be driven to emit light, the first switching element K1 and the fourth switching element K4 need to be turned on simultaneously. Since the control terminals of the first switching element K1 and the fourth switching element K4 are connected to the same first light-emitting control signal line F1, this can be achieved simply by applying a conduction voltage to the first light-emitting control signal line F1. When the second light-emitting element L2 needs to be driven to emit light, the second switching element K2 and the third switching element K3 need to be turned on simultaneously. Since the control terminals of the second switching element K2 and the third switching element K3 are connected to the same second light-emitting control signal line F2, this can be achieved simply by applying a conduction voltage to the second light-emitting control signal line F2. Furthermore, by alternately driving the first light-emitting control signal line F1 and the second light-emitting control signal line F2 in two time periods, the alternating emission of the first light-emitting element L1 and the second light-emitting element L2 connected in reverse parallel can be achieved. In this embodiment, two light-emitting control signal lines are used to selectively control four different switching elements K. Within one frame, two different light-emitting control signals are turned on sequentially. During two different time periods within the display time of one frame, light-emitting elements L with reversed conduction direction can be selectively turned on, so that light-emitting elements L connected in opposite parallel in the same sub-pixel P can emit light. This allows the lifespan of two or more light-emitting elements L to be utilized, and improves the control efficiency and reliability of the light-emitting control module 20.

[0035] Furthermore, in a light-emitting control module 20, since the second switching element K2 and the third switching element K3 are controlled by the same second light-emitting control signal line F2, and the second switching element K2 and the third switching element K3 are transistors of the same type, that is, the second switching element K2 and the third switching element K3 controlled by the same first light-emitting control signal line F1 have similar conduction characteristics; since the first switching element K1 and the fourth switching element K4 are controlled by the same first light-emitting control signal line F1, and the first switching element K1 and the fourth switching element K4 are transistors of the same type, that is, the first switching element K1 and the fourth switching element K4 controlled by the same first light-emitting control signal line F1 have similar conduction characteristics, thereby ensuring the timing and voltage symmetry of the current loop and improving the uniformity and reliability of the sub-pixel P.

[0036] By configuring transistors connected to the same light-emitting control signal line to be of the same type, for example, the first switching element K1 and the fourth switching element K4 are both N-type transistors, and the second switching element K2 and the third switching element K3 are both P-type transistors; or, the first switching element K1 and the fourth switching element K4 are both P-type transistors, and the second switching element K2 and the third switching element K3 are both N-type transistors; or, the first switching element K1, the second switching element K2, the third switching element K3, and the fourth switching element K4 are all N-type transistors or P-type transistors, etc. This disclosure does not limit the type of switching element K connected to the same light-emitting control signal line. Using the same type of switching element K helps simplify the manufacturing process of the transistor array, reducing manufacturing difficulty and cost.

[0037] Thus, by connecting the control terminals of the second switching element K2 and the third switching element K3 to the same second light-emitting control signal line F2, and connecting the control terminals of the first switching element K1 and the fourth switching element K4 to the same first light-emitting control signal line F1, the control signal lines of the switching elements K can be merged. This halves the number of control signal lines without sacrificing the bidirectional time-division driving function, simplifying wiring and reducing the space occupied by the display panel 100. Setting the second switching element K2 and the third switching element K3 to the same type of transistor, and the first switching element K1 and the fourth switching element K4 to the same type of transistor, improves the symmetry and uniformity of the light-emitting control module 20 through transistor type matching, simplifying the process and reducing manufacturing difficulty.

[0038] Please refer to Figure 2 and Figure 3 In a display panel 100 provided in this disclosure, the first switching element K1 and the second switching element K2 are connected to the output terminal 11 of the same pixel circuit 10.

[0039] Specifically, in this embodiment, both the first switching element K1 and the second switching element K2 obtain driving current or driving voltage from the same output terminal 11 of the pixel circuit 10. Therefore, regardless of whether the pixel circuit 10 controls brightness by outputting current or by outputting voltage, the first light-emitting element L1 and the second light-emitting element L2 emit light based on the same set of grayscale data. That is, the pixel circuit 10 only needs to design one output terminal 11 to transmit grayscale data, and the driving of the two light-emitting elements L is converged to the same output node of the pixel circuit 10; there is no need to design two independent output terminals 11 with different logics to drive the first light-emitting element L1 and the second light-emitting element L2 respectively, which helps to simplify the complexity of the pixel circuit 10 and also helps to design the light-emitting control module 20 more compactly, reducing the wiring complexity within the sub-pixel P.

[0040] Although the first light-emitting element L1 and the second light-emitting element L2 are connected to the same output terminal 11 of the pixel circuit 10, they are connected in parallel in opposite directions. Furthermore, the conduction of the first switching element K1 and the second switching element K2 is controlled independently in a time-division manner. When the first switching element K1 is on, the output current of the pixel circuit 10 is directed to flow through the first light-emitting element L1; when the second switching element K2 is on, the output current of the pixel circuit 10 is directed to flow through the second light-emitting element L2. The current direction of the second light-emitting element L2 is opposite to that of the first light-emitting element L1. In other words, a single driving signal can be used to control the direction of the output current of the pixel circuit 10 through specific connections and combinations of the switching elements K, thereby achieving time-division driving of the anti-parallel light-emitting elements L in a sub-pixel P, thus improving the lifespan of the light-emitting elements L.

[0041] Thus, by connecting the first switching element K1 and the second switching element K2 to the output terminal 11 of the same pixel circuit 10, the wiring of the pixel circuit 10 can be simplified, and the light-emitting elements L connected in opposite parallel within the same light-emitting control module 20 can emit light based on the same set of grayscale data output from the output terminal 11 of the same pixel circuit 10, which is beneficial to improving the light-emitting stability and display effect of the sub-pixel P.

[0042] Figure 4 As shown Figure 1 Another circuit connection diagram for neutron pixels. Figure 5 The diagram shown is a timing control diagram provided in an embodiment of this disclosure. Please refer to it. Figures 3 to 5 In a display panel 100 provided in this disclosure, the display panel 100 includes a first data signal line X1, which is connected to a pixel circuit 10. The display panel 100 includes a first scanning stage S1, and the first data signal line X1 is used to provide a data signal DATA to the pixel circuit 10 in the first scanning stage S1.

[0043] Specifically, the first data signal line X1 is used to accurately transmit the data signal DATA (representing the grayscale or brightness information of the pixel) to the pixel circuit 10 connected thereto during the first scanning stage S1. The pixel circuit 10 receives and stores the data signal DATA, which determines the luminous brightness of the pixel throughout the entire display frame.

[0044] In this embodiment, the first switching element K1 and the second switching element K2, which are connected in reverse parallel, are connected to the output terminal 11 of the same pixel circuit 10. The pixel circuit 10 is connected to the first data signal line X1. At this time, the display panel 100 only includes the first scanning stage S1. Please refer to... Figure 4The pixel circuit 10 includes a switching transistor T1, a driving transistor T0, and a storage capacitor Cst, wherein the drain of the driving transistor T0 is connected to the first input terminal 21 of the light emission control module 20. Figure 4 The illustration uses a 2T1C circuit as an example for pixel circuit 10. Optionally, pixel circuit 10 can also be a 7T1C circuit or an 8T2C circuit, etc., and this disclosure does not limit it. Switching transistor T1 is turned on or off under the control of scan control signal SCAN. When switching transistor T1 is a P-type transistor, it is turned on when scan control signal SCAN is low, and the data signal DATA voltage is stored in storage capacitor Cst. When driving transistor T0 is a P-type transistor, it is turned on when data signal DATA is low, and the driving transistor T0 converts the voltage difference between the power supply voltage VDD and the data signal DATA voltage into a driving current, which is transmitted to the light-emitting control module 20. The above is only an example. Optionally, switching transistor T1 and driving transistor T0 can also be N-type transistors. Correspondingly, when switching transistor T1 is an N-type transistor, it is turned on when scan control signal SCAN is high, and when driving transistor T0 is an N-type transistor, it is turned on when data signal DATA is high. This disclosure does not limit it.

[0045] Please combine Figure 5 The emission of sub-pixel P includes two emission periods. In the first period t1, the second emission control signal EM2 transmitted by the second emission control signal line F2 controls the second switching element K2 and the third switching element K3 to turn on, and the second emission element L2 emits light. In the second period t2, the first emission control signal EM1 transmitted by the first emission control signal line F1 controls the first switching element K1 and the fourth switching element K4 to turn on, and the first emission element L1 emits light. Figure 5 This illustration only shows the case where the first switching element K1 to the fourth switching element K4 are all P-type transistors and are all turned on when the light-emitting control signal is low. Optionally, the first switching element K1 to the fourth switching element K4 can also be all N-type transistors and can be turned on when the light-emitting control signal is high. Alternatively, some can be P-type transistors and some can be N-type transistors. Further details will not be provided.

[0046] Thus, when the display panel 100 only has the first scanning stage S1, the sub-pixel P provides a data signal DATA through a first data signal line X1. By selectively turning on different switching elements K in the light emission control module 20, the switching elements K connected in reverse parallel can emit light alternately without adding extra wiring.

[0047] Figure 6 The diagram shown is another timing control diagram provided in an embodiment of this disclosure. Figure 7 As shown Figure 1 Please refer to another circuit connection diagram for neutron pixels. Figure 3 , Figure 6 and Figure 7 In a display panel 100 provided in this disclosure, the display panel 100 includes a first data signal line X1, which is connected to a pixel circuit 10; the display panel 100 includes a first scanning phase S1 and a second scanning phase S2, the first data signal line X1 is used to provide a first data signal DATA1 to the pixel circuit 10 in the first scanning phase S1, and the first data signal line X1 is used to provide a second data signal DATA2 to the pixel circuit 10 in the second scanning phase S2.

[0048] In this embodiment, the display panel 100 has two scanning stages, that is, two data signal writing operations. Optionally, the data signal voltages in the two scanning stages can be the same or different. Please refer to... Figure 3 and Figure 6 When the number of anti-parallel light-emitting elements L is the same, the data signal voltage written in the two scanning stages can be the same. Please refer to... Figure 7 When the number of anti-parallel light-emitting elements L is inconsistent, the data signal voltage written in the two scanning phases can be different. Figure 7 The illustration only uses the example of the light-emitting control module 20, which includes two first light-emitting elements L1 and one second light-emitting element L2, and does not represent the actual number of anti-parallel light-emitting elements L contained in the light-emitting control module 20. Specifically, since the number of forward-connected first light-emitting elements L1 is different from the number of reverse-connected second light-emitting elements L2, different data signal voltages are required when lighting light-emitting elements L in different directions, so as to output different currents to adapt to the number of light-emitting elements L and improve the brightness uniformity of different light-emitting stages.

[0049] Thus, by setting two scanning stages, the same or different data signals can be transmitted in different scanning stages to match the number of forward and reverse light-emitting elements L in different types of light-emitting control modules 20, thereby improving the brightness uniformity in different light-emitting stages. Transmitting the same or different data signals twice via a single data line enables data line reuse, reducing the number of wires required.

[0050] Figure 8 As shown Figure 1 Another circuit connection diagram for neutron pixels. Figure 9 for Figure 8 For the timing control diagram, please refer to... Figure 8 and Figure 9In one optional embodiment provided in this disclosure, the sub-pixel P further includes a gating module 30, wherein the control terminals of the first switching element K1 and the fourth switching element K4 are connected to the first gating module 31 via the first light-emitting control signal line F1, and the control terminals of the second switching element K2 and the third switching element K3 are connected to the second gating module 32 via the second light-emitting control signal line F2. It should be noted that, although... Figure 8 The diagram illustrates that the control terminals of the first switching element K1 and the fourth switching element K4 are respectively connected to the first gating module 31, but in reality, the control terminals of the first switching element K1 and the fourth switching element K4 are connected to the same first gating module 31; similarly, although Figure 8 The diagram shows that the control terminals of the second switching element K2 and the third switching element K3 are connected to the second gating module 32, but in reality, the control terminals of the second switching element K2 and the third switching element K3 are connected to the same second gating module 32.

[0051] Please combine Figure 9 In the first scanning stage S1, the first data signal line X1 writes the data signal DATA into the pixel circuit 10. At this time, the third transistor T3 in the first gating module 31 is cut off under the high level signal of EM1_DATA, and the first switching element K1 and the fourth switching element K4 are cut off. The fourth transistor T4 in the second gating module 32 is turned on under the low level signal of EM2_DATA, and the second switching element K2 and the third switching element K3 are turned on. The light emission control signal EMIT is provided to the second light emission element L2 through the second light emission control signal line F2, and the second light emission element L2 emits light. Conversely, in the second scanning stage S2, the first data signal line X1 writes the data signal DATA into the pixel circuit 10. At this time, the third transistor T3 in the first gating module 31 is turned on under the low level signal of EM1_DATA, and the first switching element K1 and the fourth switching element K4 are turned on; the fourth transistor T4 in the second gating module 32 is turned off under the high level signal of EM2_DATA, and the second switching element K2 and the third switching element K3 are turned off. The light emission control signal EMIT is provided to the first light emission element L1 through the first light emission control signal line F1, and the first light emission element L1 emits light.

[0052] Figure 10 As shown Figure 1 Another circuit connection diagram for neutron pixels. Figure 11 for Figure 10 The timing control diagram; please refer to Figure 10 and Figure 11In a display panel 100 provided in this disclosure, the pixel circuit 10 in a sub-pixel P includes a first pixel circuit 13 and a second pixel circuit 14. A first switching element K1 is connected to the output terminal 131 of the first pixel circuit 13, and a second switching element K2 is connected to the output terminal 141 of the second pixel circuit 14.

[0053] In one optional embodiment provided in this disclosure, a sub-pixel P includes two independent pixel circuits 10, which are used to drive a first switching element K1 and a second switching element K2, respectively. The first switching element K1 is connected between the output terminal 131 of the first pixel circuit 13 and the first node N1, and the second switching element K2 is connected between the output terminal 141 of the second pixel circuit 14 and the second node N2; the first node N1 is connected to the positive terminal of the first light-emitting element L1 and the negative terminal of the second light-emitting element L2, and the second node N2 is connected to the negative terminal of the first light-emitting element L1 and the positive terminal of the second light-emitting element L2. The display panel 100 includes a first light-emitting control signal line F1 and a second light-emitting control signal line F2. The first light-emitting control signal line F1 is connected to the control terminal of the first switching element K1, and the second light-emitting control signal line F2 is connected to the control terminal of the second switching element K2; the first switching element K1 and the second switching element K2 are time-divisionally turned on.

[0054] Thus, by setting two independent pixel circuits 10 in a sub-pixel P, these two independent pixel circuits 10 can control the first light-emitting element L1 and the second light-emitting element L2 to emit light during two independent light-emitting periods within the display time of a frame. The brightness and driving timing of these two light-emitting periods are independent of each other, which is beneficial to improving the uniformity and stability of the display.

[0055] Please continue to refer to this. Figure 10 and Figure 11 In a display panel 100 provided in this disclosure, the pixel circuit 10 includes a first data signal line X1 and a second data signal line X2. The first data signal line X1 is connected to the first pixel circuit 13, and the second data signal line X2 is connected to the second pixel circuit 14. The display panel 100 includes a first scanning stage S1. The first data signal line X1 is used to provide a first data signal DATA1 to the first pixel circuit 13 in the first scanning stage S1, and the second data signal line X2 is used to provide a second data signal DATA2 to the second pixel circuit 14 in the first scanning stage S1.

[0056] Specifically, the first pixel circuit 13 receives and stores the first data signal DATA1, which is used to drive the first light-emitting element L1 to emit light. The second pixel circuit 14 receives and stores the second data signal DATA2, which is used to drive the second light-emitting element L2 to emit light. The brightness of the first light-emitting element L1 is controlled by the first data signal DATA1, and the brightness of the second light-emitting element L2 is controlled by the second data signal DATA2. This allows the brightness and driving timing of the first and second light-emitting elements L1 and L2, which are connected in opposite parallel, to be completely independently controlled without affecting each other. Compared with the previous embodiment where only one pixel circuit 10 output terminal 11 exists in a sub-pixel P and is switched by a time-division switch, this embodiment provides higher control freedom and precision.

[0057] In this embodiment, a sub-pixel P contains two independent pixel circuits 10, and each pixel circuit 10 is connected to an independent data signal line. When only the first scanning stage S1 exists in the display panel 100, the first data signal DATA1 and the second data signal DATA2 are simultaneously written to the first pixel circuit 13 and the second pixel circuit 14 in the same scanning stage. Compared to using only one data line to write two different sets of data signals in a time-division manner (requiring two scans), this embodiment can complete twice the data signal writing within one scan cycle, greatly improving data transmission efficiency and the refresh rate of the display panel 100.

[0058] The first pixel circuit 13 and the second pixel circuit 14 each receive data from independent data signal lines. The first data signal line X1 and the second data signal line X2 can carry the same or different data signals. The first data signal DATA1 determines the brightness of the first light-emitting element L1, and the second data signal DATA2 determines the brightness of the second light-emitting element L2, enabling time-division dual-light-emitting control. Understandably, this embodiment can also be applied to situations where the number of first light-emitting elements L1 differs from the number of second light-emitting elements L2. The data signal voltage supplied to the corresponding pixel circuit 10 can be adjusted according to the number of light-emitting elements L1, improving driving accuracy and brightness uniformity, which will not be elaborated further.

[0059] Thus, by connecting two independent pixel circuits 10 within the same sub-pixel P to independent data signal lines, two different sets of data signals can be written within one scan cycle, which is beneficial for improving data transmission efficiency and the refresh rate of the display panel 100. The independent data signal lines can provide the same or different data signals to different pixel circuits 10, which is beneficial for improving driving accuracy and adapting to various different arrangements of light-emitting elements L.

[0060] Figure 12 The diagram shown is a flowchart of a display panel driving method according to an embodiment of this disclosure. Please refer to it. Figures 1 to 12This disclosure provides a driving method for a display panel 100, used to drive the display panel 100 as described above, including: step M1, the display time of a frame of the display panel 100 includes a first time period t1 and a second time period t2; step M2, during the first time period t1, the light emission control module 20 controls the first light emission element L1 to emit light, and during the second time period t2, the light emission control module 20 controls the second light emission element L2 to emit light.

[0061] Within the display time of one frame on the display panel 100, different light-emitting elements L in the same sub-pixel P emit light twice. The first light-emitting element L1 emits light in the first time period t1, and the second light-emitting element L2 emits light in the second time period t2, or vice versa. That is, the first light-emitting element L1 and the second light-emitting element L2 work alternately in different time periods, which can balance the average usage intensity and cumulative working time of different light-emitting elements L, help improve the utilization rate of light-emitting elements L, extend the effective working life of the entire sub-pixel P, and delay the occurrence of brightness decay and color shift.

[0062] Please refer to Figure 3 and Figure 5 In a driving method for a display panel 100 provided in this disclosure, the light-emitting control module 20 includes a first switching element K1 and a second switching element K2. The first switching element K1 is connected between the pixel circuit 10 and the first light-emitting element L1, and the second switching element K2 is connected between the pixel circuit 10 and the second light-emitting element L2. The display panel 100 includes a first scanning phase S1. In the first scanning phase S1, the pixel circuit 10 is controlled to output a data signal DATA. In a first time period t1, the first switching element K1 is controlled to be turned on, and in a second time period t2, the second switching element K2 is controlled to be turned on.

[0063] The driving method provided in this embodiment is applied to a situation where a sub-pixel P includes only one pixel circuit 10, and the display panel 100 includes only the first scanning phase S1. The first input terminal 21 of the light-emitting control module 20 is connected to the output terminal 11 of the pixel circuit 10, and the second input terminal 22 of the light-emitting control module 20 is connected to the first common voltage signal line Y1. Further, the first light-emitting element L1 in the light-emitting control module 20 is connected to one output terminal 11 of the pixel circuit 10 through a first switching element K1, and the second light-emitting element L2 in the light-emitting control module 20 is connected to the same output terminal 11 of the pixel circuit 10 through a second switching element K2. In the first scanning phase S1, the pixel circuit 10 outputs a data signal DATA. In the first time period t1, the second light-emitting control signal EM2 controls the second switching element K2 and the third switching element K3 to conduct, and the second light-emitting element L2 emits light. In the second time period t2, the first light-emitting control signal EM1 controls the first switching element K1 and the fourth switching element K4 to conduct, and the first light-emitting element L1 emits light.

[0064] In this embodiment, the entire sub-pixel P requires only one pixel circuit 10 to receive, store, and output the data signal DATA. This eliminates the need for separate pixel circuits 10 for the first and second light-emitting elements L1 and L2, which are connected in opposite parallel configurations, thus reducing the number of transistors and wiring within the sub-pixel P. The pixel circuit 10 outputs the data signal DATA, which is distributed to the first and second light-emitting elements L1 and L2 in a time-division multiplexing manner via the first switching element K1 and the second switching element K2. By precisely controlling the conduction timing of the first switching element K1 and the second switching element K2, the light-emitting period and duration of the first and second light-emitting elements L1 and L2 can be independently determined, achieving fine-grained timing control.

[0065] Thus, the driving method provided in this embodiment can use a single pixel circuit 10 to output a single data signal. With the help of a time-division switch, it can realize the time-division driving of the light-emitting elements L connected in opposite parallel within the same sub-pixel P. Under fine timing control, it can also simplify the pixel structure.

[0066] Please refer to Figure 3 , Figure 6 In a driving method for a display panel 100 provided in this disclosure, the light-emitting control module 20 includes a first switching element K1 and a second switching element K2. The first switching element K1 is connected between the pixel circuit 10 and the first light-emitting element L1, and the second switching element K2 is connected between the pixel circuit 10 and the second light-emitting element L2. The display panel 100 includes a first scanning phase S1 and a second scanning phase S2. A first time period t1 is located between the first scanning phase S1 and the second scanning phase S2, and a second time period t2 is located after the second scanning phase. In the first scanning phase S1, the pixel circuit 10 is controlled to output a first data signal DATA1, and in the second scanning phase S2, the pixel circuit 10 is controlled to output a second data signal DATA2. In the first time period t1, the first switching element K1 is controlled to be turned on, and in the second time period t2, the second switching element K2 is controlled to be turned on.

[0067] The driving method provided in this embodiment is applied to a scenario where a sub-pixel P includes a pixel circuit 10, and the display panel 100 includes a first scanning phase S1 and a second scanning phase S2. In the first scanning phase S1, the pixel circuit 10 outputs a first data signal DATA1. A first time period t1 is located between the first scanning phase S1 and the second scanning phase S2. During the first time period t1, a first light-emitting control signal controls the second switching element K2 and the third switching element K3 to turn on, and the second light-emitting element L2 emits light. In the second scanning phase S2, the pixel circuit 10 outputs a second data signal DATA2. A second time period t2 is located after the second scanning phase S2. During the second time period t2, a second light-emitting control signal controls the first switching element K1 and the fourth switching element K4 to turn on, and the first light-emitting element L1 emits light.

[0068] In this embodiment, the entire sub-pixel P requires only one pixel circuit 10 to receive, store, and output the first data signal DATA1 and the second data signal DATA2. This eliminates the need for separate pixel circuits 10 for the anti-parallel first light-emitting element L1 and the second light-emitting element L2, reducing the number of transistors and wiring within the sub-pixel P. The pixel circuit 10 receives and processes two independent sets of data signals in two different scanning phases, allowing for updates or adjustments based on different data. Completely independent control of the brightness and emission timing of the first light-emitting element L1 and the second light-emitting element L2 improves driving flexibility. The first time period t1, located between the first scanning phase S1 and the second scanning phase S2, ensures that the first light-emitting element L1 uses the latest first data signal DATA1 for emission; the second time period t2, located after the second scanning phase S2, ensures that the second light-emitting element L2 uses the latest second data signal DATA2 for emission. By aligning the emission time period as close as possible to its corresponding data writing time period, the real-time performance and accuracy of grayscale display are improved.

[0069] Thus, the driving method provided in this embodiment can use a single pixel circuit 10 to write independent data signals at different scanning stages, which is beneficial to improving the independence and controllability of driving the first light-emitting element L1 and the second light-emitting element L2. It is especially suitable for situations where the number of the first light-emitting element L1 and the second light-emitting element L2 are different in anti-parallel light-emitting elements L. By writing different data signals at different scanning stages in a time-division manner, the pixel structure can be simplified without adding additional pixel circuits 10.
