When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] The present invention provides an electronic paper display module, which is applied to an electronic paper display screen. Please refer to Figure 1 , Figure 1 which is a functional block diagram of an embodiment of the electronic paper display module of the present invention. In this embodiment, the electronic paper display module includes a basic display module 100 and a camera area driving module; the basic display module 100 includes a plurality of pixel units 110, and the pixel unit 110 includes electrophoretic particles 111; the camera area driving module includes a plurality of attracting units 210, and the attracting units 210 are arranged on the side of the pixel unit 110; wherein: The attracting unit 210 is used to attract the electrophoretic particles 111 to the side of the pixel unit 110 when triggered.

[0024] The basic display module 100 is a set of devices for realizing the basic display function; it can be understood that the basic display function mainly includes controlling the movement of the electrophoretic particles 111 according to the driving signal and data signal sent by the processing device, so as to realize the display of the color corresponding to the data signal; the specific structure of the basic display module 100 can be set based on actual needs.

[0025] The basic display module 100 includes a plurality of pixel units 110, and the pixel unit 110 is the smallest display unit of the display screen; the electrophoretic particles 111 are charged particles arranged in the pixel unit 110 for indicating colors; the colors of the electrophoretic particles 111 are set according to different needs. For example, the pixel unit 110 may include black particles 1111 and white particles 1112, or may further include black particles 1111, white particles 1112, and red particles 1113, or may further include black particles 1111, white particles 1112, red particles 1113, yellow particles, and so on; the charges carried by the electrophoretic particles 111 of different colors are different. Therefore, when a voltage is applied to the pixel unit 110, the driving states of the electrophoretic particles 111 of different colors are different, so that the positions of the electrophoretic particles 111 of different colors in the pixel unit 110 are different, and the combination of the electrophoretic particles 111 located at the outermost layer determines the color displayed by the pixel unit 110.

[0026] The camera area driving unit is used to perform side attraction on the electrophoretic particles 111 according to the usage requirements of the camera; attracting the electrophoretic particles 111 to the side of the pixel unit 110 is to expose the opening area of the pixel unit 110. At this time, the camera can collect images of the outside world through the pixel unit 110. Therefore, when the camera needs to be used, side attraction is performed on the electrophoretic particles 111, and when the camera does not need to be used, side attraction is not performed on the electrophoretic particles 111, and the electrophoretic particles 111 are evenly distributed in the pixel unit 110 in the side direction; further, in this embodiment, the electrophoretic particles 111 are provided in various sizes. After stopping the side attraction on the electrophoretic particles 111, due to the different sizes of the electrophoretic particles 111, the moving speeds of the electrophoretic particles 111 in the electric field are also different. Therefore, the electrophoretic particles 111 can be redistributed evenly.

[0027] The attracting unit 210 is used to perform the attraction on the electrophoretic particles 111; the attracting unit 210 is arranged on the side of the pixel unit 110; it can be understood that the side of the pixel unit 110 refers to the edge of the opening area. In this way, after attracting the electrophoretic particles 111, the electrophoretic particles 111 can be concentrated at the edge of the opening area, and the central part of the opening area is exposed. It can be understood that since the electrophoretic particles 111 are charged, the attracting unit 210 can be set based on the voltage attraction method; the attracting unit 210 is triggered when the camera needs to be used.

[0028] It can be understood that in order to achieve specific basic display and side attraction, relevant driving chips, processing components, etc. can be set; under the principle disclosed in this application that the attraction unit 210 is triggered to perform side attraction on the electrophoretic particles 111 when the camera needs to be used, it is easy to think of detecting the state of the camera through the processing component. When the camera is running, relevant instructions are sent to the camera area driving unit to trigger the attraction unit 210 to perform side attraction on the electrophoretic particles 111, and when the camera is not running, relevant instructions are not sent to the camera area driving unit, so that the electrophoretic particles 111 are evenly distributed in the pixel unit 110 in the side direction.

[0029] In this embodiment, by setting the attraction unit 210, the electrophoretic particles 111 in the pixel unit 110 can be triggerably attracted to the side of the pixel unit 110, so that the opening area of the pixel unit 110 can be exposed. On this basis, if a camera is set below the display module, the camera can collect images of the outside world through the pixel unit 110, so that the camera does not need to occupy the area outside the display module, realizing an increase in the screen-to-body ratio.

[0030] Further, referring to Figure 2 、 Figure 3 , Figure 2 is a schematic structural diagram of a single pixel unit in the electronic paper display module of the present invention, Figure 3 is an application of the electronic paper display module of the present invention in Figure 2 a cross-sectional view taken along the B-B' direction in the embodiment; the basic display module 100 includes a first substrate 120, a second substrate 130, and a retaining wall 140. Among them, the retaining wall 140 includes a plurality of unit cofferdams, and the first substrate 120, the second substrate 130, and the unit cofferdams enclose a unit cavity, and the pixel units 110 are correspondingly arranged in the unit cavities.

[0031] The first substrate 120 is the bottommost structure of the basic display module 100, and the second substrate 130 is the outermost structure of the basic display module 100; the specific materials of the first substrate 120 and the second substrate 130 can be set based on actual needs, such as glass and plastic. Glass is taken as an example for illustration in this embodiment and subsequent embodiments.

[0032] An accommodation space for the pixel unit 110 is formed between the first substrate 120 and the second substrate 130, and the retaining wall 140 is used to divide the accommodation space into pixel units 110; from the overall view of the basic display module 100, the first substrate 120 and the second substrate 130 are filled with electrophoretic particles 111, and the retaining wall 140 separates the electrophoretic particles 111, and the electrophoretic particles 111 existing in the same space correspond to a pixel unit 110.

[0033] In this embodiment, different from the traditional forms of microcapsules and microcups, the capacitive particles are directly arranged in the unit cavity, so that there is no need to manufacture microcapsules and microcups, and at the same time, there is no need to use OCA (Optically Clear Adhesive) to bond the driving substrate and the pixel unit layer 110, reducing the manufacturing cost.

[0034] Further, the projection of the unit cofferdam on the first substrate 120 is square, and the attracting unit 210 includes an adjusting attractor unit and a common attractor unit; wherein: The adjusting attractor unit and the common attractor unit are respectively arranged on two opposite sides within the unit cofferdam.

[0035] The projection of the unit cofferdam on the first substrate 120 characterizes the pixel shape displayed by the corresponding pixel unit 110.

[0036] The adjusting attractor unit is used to output an attracting voltage, and the common attractor unit is used to output a common voltage; It can be understood that the attracting voltage is different from the common voltage. Therefore, when the adjusting attractor unit and the common attractor unit output voltages, a voltage difference is formed within the pixel unit 110, so that the electrophoretic particles 111 are attracted to the side of the pixel unit 110; In order to achieve a better attracting effect, in this embodiment, the adjusting attractor unit and the common attractor unit are respectively arranged on two opposite sides within the unit cofferdam; for example, in the clockwise direction of the positive direction of the projection, there are a first side, a second side, a third side, and a fourth side; then the adjusting attractor unit can be arranged on the first / third side, and the common attractor unit can be arranged on the third / first side, or the adjusting attractor unit can be arranged on the second / fourth side, and the common attractor unit can be arranged on the fourth / second side; ensuring that the direction of voltage attraction is clear, so that it can be ensured that the electrophoretic particles 111 are attracted to the side.

[0037] In this embodiment, the case where the projection of the unit cofferdam on the first substrate 120 is square is taken as an example for illustration. In practical applications, the projection of the unit cofferdam on the first substrate 120 can also be, but not limited to, circular or rectangular; when the projection is rectangular. The adjusting attractor unit and the common attractor unit can be arranged analogously to the square; when the projection is circular, the adjusting attractor unit and the common attractor unit can be arranged on two opposite sides of the side, for example, the adjusting attractor unit and the common attractor unit can respectively cover the sides of 1 / 4 of the circumference.

[0038] Further, referring to Figure 4 , Figure 4 This is for the application of the electronic paper display module of the present invention in Figure 2Cross-sectional view in the A-A' direction in the embodiment; the camera area driving module includes a driving signal line 220 and a first common electrode 230, the adjusting attractor unit includes a first conductive dielectric layer 2111, and the common attractor unit includes a second conductive dielectric layer 2121, where: The first conductive dielectric layer 2111 is connected to the driving signal line 220, the second conductive dielectric layer 2121 is connected to the first common electrode 230, and the first conductive dielectric layer 2111 and the second conductive dielectric layer 2121 are respectively disposed on two opposite sides within the unit cofferdam.

[0039] The driving signal line 220 is used to transmit a voltage signal sent by a processing device to trigger the attracting unit 210.

[0040] The first common electrode 230 is used to provide a common voltage.

[0041] The first conductive dielectric layer 2111 receives the voltage signal transmitted by the driving signal line 220, the second conductive dielectric layer 2121 receives the common voltage transmitted by the first common electrode 230, and a voltage difference is formed between the first conductive dielectric layer 2111 and the second conductive dielectric layer 2121.

[0042] The specific materials of the first conductive dielectric layer 2111 and the second conductive dielectric layer 2121 can be set based on actual needs. In this embodiment, the first conductive dielectric layer 2111 and the second conductive dielectric layer 2121 are ITO (Indium-Tin Oxide) conductive glass; the same applies to the subsequent third conductive dielectric layer 1122 to the sixth conductive dielectric layer 1131, which will not be elaborated further.

[0043] Further, the basic display module 100 further includes a gate driving line 150, a data line 160, and a second common electrode; the pixel unit 110 includes a filling medium, an adjusting driving subunit, and a common driving subunit; where: The filling medium is filled in the unit cavity, and the electrophoretic particles 111 are disposed in the filling medium; The adjusting driving subunit is disposed on the first substrate 120, the control end of the adjusting driving subunit is connected to the gate driving line 150, the input end of the adjusting driving subunit is connected to the data line 160, and the output end of the adjusting driving subunit is in contact with the filling medium; The common driving subunit is disposed on the second substrate 130, the common driving subunit is connected to the second common electrode, and the common driving subunit is also in contact with the filling medium.

[0044] The gate driving line 150 is used to transmit a gate driving signal; the data line 160 is used to transmit a data signal; the second common electrode is used to provide a common voltage.

[0045] The filling medium constructs a floating environment for the electrophoretic particles 111; the electrophoretic particles 111 float in the filling medium and adjust their floating positions based on voltage driving.

[0046] The adjustment driving subunit is used to output a data voltage corresponding to the data signal; the data voltage and the common voltage form a voltage difference through the filling medium, so that the electrophoretic particles 111 move based on the voltage difference between the first substrate 120 and the second substrate 130, realizing a change in the floating position of the electrophoretic particles 111.

[0047] It should be noted that when the camera needs to be used, the electrophoretic particles 111 are attracted to the side of the pixel unit 110. At this time, the corresponding pixel unit 110 does not have a display function. Therefore, when the attracting unit 210 triggers side attraction, the data signal output to the corresponding pixel unit 110 can be stopped to avoid the basic display affecting the side attraction.

[0048] Furthermore, the basic display module 100 further includes a third common electrode 180, and the adjustment driving subunit includes a driving switch transistor 1121, a third conductive medium layer 1122, a fourth conductive medium layer 1123, and a fifth conductive medium layer 1124, where: The gate of the driving switch transistor 1121 is connected to the gate driving line 150 through the third conductive medium layer 1122, the drain of the driving switch transistor 1121 is connected to the data line 160, the source of the driving switch transistor 1121 is connected to the fourth conductive medium layer 1123, and the fourth conductive medium layer 1123 is in contact with the filling medium; The fifth conductive medium layer 1124 is connected to the third common electrode 180, and the fifth conductive medium layer 1124 is disposed between the third conductive medium layer 1122 and the fourth conductive medium layer 1123.

[0049] The driving switch transistor 1121 is used to control the basic display of the pixel unit 110.

[0050] Figure 4 In this case, D is the drain of the driving switch transistor, S is the source of the driving switch transistor, and G is the gate of the driving switch transistor.

[0051] The third conductive medium layer 1122 is used to transmit the gate driving signal to the gate of the switch transistor, the fourth conductive medium layer 1123 is used to transmit the data signal to the filling medium, and the fifth conductive medium layer 1124 is used to form storage capacitors with the third conductive medium layer 1122 and the fourth conductive medium layer 1123 respectively.

[0052] The driving switch transistor 1121 is turned on or off based on the gate driving signal. When the driving switch transistor 1121 is turned on, the driving switch transistor 1121 transfers the data signal received at the drain to the source and outputs it to the fourth conductive dielectric layer 1123. A voltage difference is formed between the data signal of the fourth conductive dielectric layer 1123 and the common voltage of the common driving sub-unit based on the filling dielectric, so as to drive the electrophoretic particles 111.

[0053] Further, the common driving sub-unit includes a sixth conductive dielectric layer 1131, where: The sixth conductive dielectric layer 1131 is connected to the second common electrode, and the sixth conductive dielectric layer 1131 is also in contact with the filling dielectric.

[0054] The sixth conductive dielectric layer 1131 is used to transmit the common voltage provided by the second common electrode to the filling dielectric, so as to form a voltage difference with the data signal provided by the adjustment driving sub-unit based on the filling dielectric, and realize the driving of the electrophoretic particles 111.

[0055] Further, the basic display module 100 further includes a black photoresist 190, and the black photoresist 190 is disposed on the side of the second substrate 130 facing the first substrate 120, and the black photoresist 190 is disposed along the edge of the unit cofferdam; where: When the electrophoretic particles 111 are attracted by the attracting unit 210, the projection on the second substrate 130 is an edge projection, and the projection of the black photoresist 190 on the second substrate 130 covers the edge projection.

[0056] There are traces of control signals between the pixel units 110 and in the edge area. In order not to let the traces affect the display effect, except for the bayonet area of the pixel, it is necessary to set the BM (Black Matrix, black photoresist 190); therefore, in this embodiment, the projection of the black photoresist 190 on the second substrate 130 is set to cover the edge projection, so that when the electrophoretic particles 111 are attracted to the side, they can be completely blocked by the black photoresist 190, achieving a better exposure effect; it should be noted that in order to ensure the aperture ratio of the pixel unit 110, the area of the black photoresist 190 needs to be as small as possible on the premise of ensuring the function.

[0057] The overall principle of the electronic paper display module of the present application will be described below: When the camera does not need to collect images: the camera area driving module does not work, and the basic display module 100 normally displays based on the gate driving signal, data signal, and common voltage; When the camera needs to perform image acquisition: the basic display module 100 does not work, the driving signal line 220 and the first common electrode 230 are energized, and the electrophoretic particles 111 are attracted to the side of the pixel unit 110, and the opening area of the pixel unit 110 exposes the camera, and the camera performs image acquisition; After the camera finishes image acquisition: the camera area driving module stops working. Since the sizes of the electrophoretic particles 111 are different, the speeds at which they move in the electric field also vary. Therefore, the electrophoretic particles 111 are redistributed uniformly in the filling medium; the basic display module 100 starts working again.

[0058] The present invention also protects an electronic paper display screen. Refer to Figure 5 , the electronic paper display screen includes a camera 20 and an electronic paper display module 10, wherein the camera 20 is disposed below the electronic paper display module 10. The structure of the electronic paper display module 10 can refer to the above embodiments and will not be elaborated herein. Naturally, since the electronic paper display screen of this embodiment adopts the technical solution of the above electronic paper display module 10, this electronic paper display screen has all the beneficial effects of the above electronic paper display module 10.

[0059] Further, the pixel unit 110 where the projection of the camera 20 on the electronic paper display module 10 is located is a controllable pixel unit 110, and the attracting unit 210 is disposed on the side of the controllable pixel unit 110.

[0060] It can be understood that when the electrophoretic particles 111 in the pixel unit 110 are attracted by the attracting unit 210 to the side of the pixel unit 110, the pixel unit 110 does not have a display function. Therefore, in order to realize the under-screen camera 20 and minimize the impact on normal display as much as possible, in this embodiment, the controllable pixel unit 110 is determined. The controllable pixel unit 110 is the pixel unit 110 that affects the image acquisition of the camera 20. The projection of the camera 20 on the electronic paper display module 10 represents the pixel unit 110 through which the image acquisition area of the camera 20 needs to pass. Therefore, the attracting unit 210 is disposed in the controllable pixel unit 110, so that the controllable pixel unit 110 can expose the opening area to the camera 20 for image acquisition, meeting the image acquisition needs of the camera 20; while other pixel units 110 do not affect the image acquisition of the camera 20. Therefore, there is no need to set the relevant attracting unit 210 to avoid affecting normal display.

[0061] In practical applications, for the convenience of production, for the pixel units 110 other than the controllable pixel units 110, the same settings as the controllable pixel units 110 can be made, but the side attracting operation is not performed on them, that is, the attracting unit 210 can be set, but the side attracting is not triggered.

[0062] It can be understood that in practical applications, although the pixel unit 110 can expose the opening area to the camera 20 for image acquisition, other structures of the pixel unit 110 will still have a certain impact on image acquisition. Therefore, a relevant optimization algorithm can be set to obtain a clearer acquired image.
