[0059] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0060] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0061] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0062] The embodiment of the present disclosure provides an electronic paper display panel, as shown in FIG1 , comprising: a first base substrate 1, and a plurality of sub-pixels 2; the plurality of sub-pixels 2 are located on one side of the first base substrate;

[0063] Each sub-pixel 2 in the plurality of sub-pixels includes:

[0064] pixel electrode 3;

[0065] The common electrode 6 is located on a side of the pixel electrode 3 facing away from the first substrate 1;

[0066] The electrophoretic liquid layer 35 is located between the pixel electrode 3 and the common electrode 6 and includes a plurality of charged particles 7 , wherein the pixel electrode 3 is configured to drive the plurality of charged particles 7 to adjust the grayscale display.

[0067] In some possible embodiments, as shown in FIG. 1 , the electronic paper display panel further includes: a second base substrate 34 located on a side of the common electrode 6 facing away from the first base substrate 1 .

[0068] In a specific implementation, for example, a pixel electrode can be formed on a first base substrate to obtain a first substrate; a common electrode can be formed on a second base substrate to obtain a second substrate; an electrophoretic liquid layer can be formed on one side of the first substrate, and then a vacuum box-matching process can be used to cover the second substrate with the electrophoretic liquid layer to obtain the structure of the electronic paper display panel provided in the embodiment of the present disclosure.

[0069] In a specific implementation, the common electrodes of different sub-pixels are loaded with the same common electrode voltage. By controlling the voltages loaded on the pixel electrodes to be different, each sub-pixel can present a desired grayscale. Accordingly, in some embodiments, the common electrodes of multiple sub-pixels can be connected as a whole, that is, the common electrode is a planar electrode provided on the entire surface of one side of the second substrate. In a specific implementation, the common electrode is, for example, a transparent electrode, and the material of the common electrode includes indium tin oxide (ITO).

[0070] In some possible embodiments, in a direction perpendicular to the first substrate, the distance between the pixel electrode and the common electrode is greater than or equal to 5 micrometers and less than or equal to 20 micrometers. For example, the distance between the pixel electrode and the common electrode can be 7 micrometers, 10 micrometers, or 15 micrometers.

[0071] In some possible embodiments, as shown in FIG2 , the electronic paper display panel further includes a second insulating layer 5 located between the pixel electrode 3 and the electrophoretic liquid layer 35. The electronic paper display panel provided by the embodiments of the present disclosure further includes a second insulating layer disposed between the pixel electrode and the electrophoretic liquid layer. This prevents contact between charged particles and the pixel electrode, preventing adsorption and aggregation of charged particles at the pixel electrode that could affect the display effect. It also prevents direct contact between the pixel electrode and charged particles, resulting in electrochemical corrosion that could affect the lifespan of the electronic paper display panel.

[0072] As shown in FIG. 3 , the electronic paper display panel further includes a reflective layer 19 located between the first base substrate 1 and the electrophoretic liquid layer 35 .

[0073] The electronic paper display panel provided by the embodiment of the present disclosure includes a reflective layer, so that light can be reflected after reaching the reflective layer, thereby improving the reflectivity.

[0074] Exemplarily, light is incident from a side of the second substrate facing away from the common electrode.

[0075] For example, the larger the area of ​​the reflective layer blocked by the black charged particles is, the lower the brightness of the pixel light is; and the smaller the area of ​​the reflective layer blocked by the black charged particles is, the higher the brightness of the pixel light is.

[0076] For example, in conjunction with Figures 1 to 3, the multiple charged particles can be black charged particles, and the black charged particles are positively charged. The black charged particles move in response to the bias between the common electrode and the pixel electrode. When the voltage bias causes the black charged particles to move near the top of the electrophoretic liquid layer (i.e., near the common electrode), the black charged particles may enter the first region Z1 (e.g., to a depth of up to about 1 micron) and suppress total internal reflection (TIR). The depth of the first region Z1 may vary depending on the wavelength of the incident light, the angle of the incident light, and the refractive index of the front sheet and the medium. The incident light may be absorbed by the black charged particles, thereby producing a black state or a dark state. In such cases, the electronic paper display panel may display a dark or black color. When the black charged particles move away from the first region Z1 (e.g., by reverse bias), the light may be reflected by total internal reflection (TIR). This results in a white state or a bright state at one or more sub-pixels. The pixel electrode may be used to drive black charged particles into or out of the first region Z1 to form a combination of a black state and a white state, thereby being used to generate an image.

[0077] Exemplarily, the plurality of charged particles may also include black charged particles and white charged particles, which is not limited here.

[0078] In some embodiments, as shown in FIG. 3 , the reflective layer 19 is located between the first base substrate 1 and the pixel electrode 3 .

[0079] In some embodiments, as shown in FIG. 3 , the reflective layer 19 includes a metal material, and the electronic paper display panel further includes a first insulating layer 9 located between the reflective layer 19 and the pixel electrode 3 .

[0080] In some embodiments, as shown in FIG1 to FIG3 , the electronic paper display panel further includes a plurality of barrier structures 33. That is, the barrier structures are provided to prevent charged particles from moving toward adjacent sub-pixels.

[0081] The electronic paper display panel provided by the embodiment of the present disclosure, as shown in Figure 4, each of the multiple sub-pixels 2 may also include: a first conduction circuit 10 and a second conduction circuit 20; wherein, the first conduction circuit 10 and the second conduction circuit 20 in the same sub-pixel 2 are both coupled to the pixel electrode 3; the first conduction circuit 10 is configured to respond to the signal of the first control signal terminal CS1 and provide the reset signal of the reset signal terminal RE to the pixel electrode 3; the second conduction circuit 20 is configured to respond to the signal of the second control signal terminal CS2 and provide the data signal of the data signal terminal DA to the pixel electrode 3; wherein, the first conduction circuit 10 and the second conduction circuit 20 in the same sub-pixel 2 work in a time-sharing manner.

[0082] In some embodiments of the present disclosure, as shown in Figure 4, the electronic paper display panel also includes: a gate driving circuit 30, including multiple shift registers SR, and the first control signal terminal CS1 corresponding to the first conduction circuit 10 in the same sub-pixel 2 and the second control signal terminal CS2 corresponding to the second conduction circuit 20 are connected to different shift registers.

[0083] The disclosed embodiments control the signal on the pixel electrode through the interaction of a gate drive circuit, a first conduction circuit, and a second conduction circuit. By controlling the first and second conduction circuits in the same sub-pixel to operate in a time-sharing manner through the gate drive circuit, the use of integrated circuit chips (ICs) can be reduced, thereby lowering production costs.

[0084] In some embodiments of the present disclosure, as shown in Figure 5, the first conduction circuit 10 includes: a first transistor T1; wherein the gate of the first transistor T1 is coupled to the first control signal terminal CS1, the first electrode of the first transistor T1 is coupled to the reset signal terminal RE, and the second electrode of the first transistor T1 is coupled to the pixel electrode 3.

[0085] For example, the first transistor T1 can be turned on under the control of the active level of the first control signal transmitted by the first control signal terminal CS1, and can be turned off under the control of the inactive level of the first control signal. For example, if the first transistor T1 is configured as a P-type transistor, the active level of the first control signal is a low level, and the inactive level of the first control signal is a high level. Alternatively, if the first transistor T1 is configured as an N-type transistor, the active level of the first control signal is a high level, and the inactive level of the first control signal is a low level.

[0086] In some embodiments of the present disclosure, as shown in Figure 5, the second conduction circuit 20 includes: a second transistor T2; wherein the gate of the second transistor T2 is coupled to the second control signal terminal CS2, the first electrode of the second transistor T2 is coupled to the data signal terminal DA, and the second electrode of the second transistor T2 is coupled to the pixel electrode 3.

[0087] For example, the second transistor T2 can be turned on under the control of the active level of the second control signal transmitted by the second control signal terminal CS2, and can be turned off under the control of the inactive level of the second control signal. For example, if the second transistor T2 is configured as a P-type transistor, the active level of the second control signal is a low level, and the inactive level of the second control signal is a high level. Alternatively, if the second transistor T2 is configured as an N-type transistor, the active level of the second control signal is a high level, and the inactive level of the second control signal is a low level.

[0088] In some embodiments of the present disclosure, as shown in Figures 4 and 5, it also includes: multiple first scanning signal lines Cs1 and multiple second scanning signal lines Cs2; wherein, the first control signal terminals CS1 corresponding to a row of sub-pixels 2 are all coupled to a first scanning signal line Cs1 among the multiple first scanning signal lines Cs1; the second control signal terminals CS2 corresponding to a row of sub-pixels 2 are all coupled to a second scanning signal line Cs2 among the multiple second scanning signal lines Cs2.

[0089] In some embodiments of the present disclosure, as shown in Figures 4 and 5, multiple shift registers SR include: multiple first shift registers (for example, SR_A1, SR_A2, SR_An in Figure 5), multiple second shift registers (for example, SR_B1, SR_B2, SR_Bn in Figure 5); one first shift register (for example, SR_A1, SR_A2, SR_An in Figure 5) among the multiple first shift registers (for example, SR_A1, SR_A2, SR_An in Figure 5) is coupled to a first scan signal line Cs1 among the multiple first scan signal lines Cs1; one second shift register (for example, SR_B1, SR_B2, SR_Bn in Figure 5) among the multiple second shift registers (for example, SR_B1, SR_B2, SR_Bn in Figure 5) is coupled to a second scan signal line Cs2 among the multiple second scan signal lines Cs2.

[0090] Exemplarily, as shown in FIG6 , the electronic paper display panel further includes: a trigger signal line (e.g., STVA and STVB in FIG6 ), a clock signal line (e.g., CLK1, CLK2, CLK3, and CLK4 in FIG6 ). Multiple first shift registers (e.g., SR_A1, SR_A2, SR_A3, and SR_An in FIG6 ) all include output signal terminals (e.g., OUTA1, OUTA2, OUTA3, and OUTAn in FIG6 ) and reset signal terminals (e.g., RSA1, RSA2, RSA3, and RSAn in FIG6 ). Multiple second shift registers (e.g., SR_B1, SR_B2, SR_B3, and SR_Bn in FIG6 ) all include output signal terminals (e.g., OUTB1, OUTB2, OUTB3, and OUTBn in FIG6 ) and reset signal terminals (e.g., RSB1, RSB2, RSB3, and RSBn in FIG6 ). The trigger signal for the first-stage shift register is derived from the signal loaded on the trigger signal line, while the signal at the output signal terminal of the previous-stage shift register serves as the trigger signal for the next-stage shift register, and the signal at the output signal terminal of the next-stage shift register serves as the signal at the reset signal terminal of the previous-stage shift register. For example, the first shift register SR_A1 is coupled to the trigger signal line STVA, and the signal at the output signal terminal OUTA1 of the first shift register SR_A1 serves as the trigger signal for the first shift register SR_A2, while the signal at the output signal terminal OUTA2 of the first shift register SR_A2 serves as the signal at the reset signal terminal RSA1 of the first shift register SR_A1.

[0091] In some embodiments of the present disclosure, as shown in Figure 5, it also includes: multiple reset signal lines (for example, Re1, Re2, Ren in Figure 5) and multiple data lines (for example, Da1, Da2, Dan in Figure 5); wherein, the reset signal terminal RE corresponding to a column of sub-pixels 2 is coupled to one reset signal line (for example, Re1, Re2, Ren in Figure 5) among the multiple reset signal lines (for example, Re1, Re2, Ren in Figure 5); the data signal terminal DA corresponding to a column of sub-pixels 2 is coupled to one data line (for example, Da1, Da2, Dan in Figure 5) among the multiple data lines (for example, Da1, Da2, Dan in Figure 5).

[0092] Exemplarily, as shown in Figure 5, multiple source drive input terminals (for example, SDP1, SDP2, SDPn in Figure 5) are also included, and one data line (for example, Da1, Da2, Dan in Figure 5) among the multiple data lines (for example, Da1, Da2, Dan in Figure 5) is coupled to one source drive input terminal (for example, SDP1, SDP2, SDPn in Figure 5) among the multiple source drive input terminals (for example, SDP1, SDP2, SDPn in Figure 5).

[0093] For example, the first electrode of the transistor can be its source electrode, and the second electrode can be its drain electrode. Alternatively, the first electrode can be its drain electrode, and the second electrode can be its source electrode. This is not limited here.

[0094] Generally, transistors using low-temperature polysilicon (LTPS) as active layers have high mobility and can be made thinner and smaller, with lower power consumption. In a specific implementation, the active layer of at least one of the transistors can be made of low-temperature polysilicon. This allows the transistor to be configured as an LTPS transistor, thereby achieving high mobility, thinner and smaller size, and lower power consumption.

[0095] Generally, transistors using metal oxide semiconductor materials as active layers have low leakage current. Therefore, in order to reduce leakage current, in some embodiments of the present disclosure, the active layer of at least one transistor may include a metal oxide semiconductor material, such as IGZO (Indium Gallium Zinc Oxide). Of course, other metal oxide semiconductor materials are also possible and are not limited here. In this way, the transistor can be configured as an oxide thin film transistor to reduce leakage current.

[0096] Generally, amorphous silicon (a-Si) material can also be used as the active layer. In specific implementation, the material of the active layer of the at least one transistor can be set to amorphous silicon, so that the transistor can be set as an a-Si type transistor.

[0097] For example, all transistors can be configured as LTPS transistors. Alternatively, all transistors can be configured as oxide transistors. Since metal oxides are relatively low-cost, there is no need to use laser equipment for crystallization. Alternatively, some transistors can be configured as oxide transistors, while the remaining transistors can be configured as LTPS transistors. Alternatively, all transistors can be configured as a-Si transistors.

[0098] For example, as shown in FIG4 and FIG5 , the voltage applied to the common electrode 6 is the common electrode voltage Vcom. In practical applications, the specific value of the common electrode voltage Vcom can be designed and determined according to the actual application environment and is not limited here.

[0099] The driving method of the electronic paper display panel provided by the embodiment of the present disclosure, as shown in FIG7 , includes:

[0100] S100, in the first stage, the first conduction circuit provides a reset signal from the reset signal terminal to the pixel electrode in response to a signal from the first control signal terminal;

[0101] S200, second stage, the second conduction circuit responds to the signal of the second control signal terminal and provides the data signal of the data signal terminal to the pixel electrode;

[0102] The first conducting circuit and the second conducting circuit in the same sub-pixel operate in a time-sharing manner.

[0103] In some embodiments of the present disclosure, the reset signal input to the pixel electrode in the same sub-pixel has an opposite potential to that of the data signal. For example, if the reset signal input to the pixel electrode in the same sub-pixel is a high potential signal, the data signal is a low potential signal. Alternatively, if the reset signal input to the pixel electrode in the same sub-pixel is a low potential signal, the data signal is a high potential signal. This is not limited here. By setting the reset signal input to the pixel electrode in the same sub-pixel to have an opposite potential to that of the data signal, DC balance can be achieved to prevent low potential accumulation or high potential accumulation in the pixel electrode.

[0104] In some embodiments of the present disclosure, the potential of the reset signal input to the pixel electrode of each sub-pixel is a fixed potential. In actual applications, the specific value of the potential of the reset signal can be designed and determined according to the actual application environment and is not limited here.
