Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to electronic ink display modules, manufacturing methods and display panels. Background Technology

[0002] In the prior art, the display module of an electronic ink screen typically includes a common electrode layer, an electronic ink capsule layer, and an array substrate stacked sequentially. The array substrate is provided with multiple thin-film field-effect transistors arranged in an array. The display operation of the electronic ink capsule in the area corresponding to each thin-film field-effect transistor is controlled by the voltage difference formed between the pixel electrode on the multiple thin-film field-effect transistors and the common electrode, thereby realizing the display of the electronic ink screen.

[0003] The drawback of existing technology is that thin-film field-effect transistors (TFTs) are typically only placed on the array substrate in the area corresponding to the display area of ​​the e-ink screen. These TFTs are covered with corresponding e-ink capsule layers and common electrodes. Furthermore, it should be noted that the e-ink capsule layers usually need to be attached to the common electrodes. Because the common electrodes need to reserve space for connection to the driving module, the projected area of ​​the common electrode and e-ink capsule layers on the array substrate is usually larger than the projected area of ​​multiple TFTs. Based on this structure, the driving module is usually located on the side where the reserved portion of the common electrode is located. This driving module is also used to connect to multiple TFTs via data lines. When the data lines have a certain width, they can act like pixel electrodes, creating a voltage difference between the data lines and the reserved portion of the common electrode. Due to the aforementioned characteristic that the e-ink capsule layers need to be attached to the common electrode, e-ink capsules also exist between the common electrode and the data lines. This voltage difference causes these e-ink capsules to enter a display state corresponding to that voltage difference, rather than a pure black display state. This results in abnormal edge display phenomena on the e-ink screen, leading to poor display quality of existing e-ink screens. Summary of the Invention

[0004] The main technical problem addressed in this application is how to reduce or eliminate edge image abnormalities on e-ink screens, thereby improving the display effect of e-ink screens.

[0005] To solve the aforementioned technical problems, the first technical solution adopted in this application is: an electronic ink display module, comprising: an array substrate, the array substrate being divided into a first region and a second region, wherein a plurality of thin-film field-effect transistors are disposed in the first region; an insulating layer, the insulating layer being disposed on the array substrate and located in the second region; a first common electrode layer, the first common electrode layer being disposed on the side of the insulating layer away from the array substrate; a second common electrode layer, wherein an electronic ink capsule layer is disposed on one side of the second common electrode layer, the electronic ink capsule layer covering the first region and the first common electrode layer; and a driving module, wherein data lines connected to each thin-film field-effect transistor are connected to the driving module through the second region to receive data signals, and the first common electrode layer and the second common electrode layer are respectively connected to the driving module to receive common electrode signals.

[0006] The projection of the insulating layer onto the array substrate overlaps at least partially with the projection of the data line onto the array substrate.

[0007] In this case, the projection of the insulating layer on the array substrate covers the entire projection of the data line in the second region on the array substrate.

[0008] The array substrate is divided into a first region, a second region, and a third region; the second region is sandwiched between the first region and the third region, and the driving module is located in the third region.

[0009] The insulating layer is a SiNx layer.

[0010] The array consists of multiple thin-film field-effect transistors, and the scan lines connected to each thin-film field-effect transistor are connected to the driving module to receive scan signals.

[0011] The first common electrode layer and the second common electrode layer are respectively connected to a common line located on the array substrate through corresponding connectors, and the common line is connected to the driving module.

[0012] The first common electrode layer and the second common electrode layer are connected to a common line located on the array substrate through the same connector, and the common line is connected to the driving module.

[0013] To solve the aforementioned technical problems, the second technical solution adopted in this application is: a method for manufacturing an electronic ink display module, the method being applied to the manufacture of the aforementioned electronic ink display module; the method includes: generating an array substrate, the array substrate being divided into a first region and a second region, a plurality of thin-film field-effect transistors being disposed in the first region, and data lines connected to each thin-film field-effect transistor being connected to a corresponding driving module through the second region to receive data signals; disposing an insulating layer on the second region of the array substrate; disposing a first common electrode layer on the insulating layer; disposing a second common electrode layer on the first region of the array substrate and on the first common electrode layer, an electronic ink capsule layer being disposed on one side of the second common electrode layer, the electronic ink capsule layer covering the first region and the first common electrode layer; the first common electrode layer and the second common electrode layer being respectively connected to a driving module to receive common electrode signals.

[0014] To solve the above-mentioned technical problems, the third technical solution adopted in this application is: a display panel, including a power module and the above-mentioned electronic ink display module.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, the technical solution of this application divides the array substrate into a first region and a second region. Multiple thin-film field-effect transistors are located in the first region, and an insulating layer is disposed on the array substrate and located in the second region. A first common electrode layer is also disposed on the insulating layer. A second common electrode layer and an electronic ink capsule layer disposed on one side cover the first region and the first common electrode layer. The data lines connected to the thin-film field-effect transistors are connected to the corresponding driving modules through the second region. Based on the above method, the insulating layer can insulate the first common electrode layer from the data lines. Furthermore, by enabling the first and second common electrode layers to receive the common electrode signal from the driving module, there is no voltage difference between the portion of the second common electrode layer located in the second region and the first common electrode layer. Consequently, the portion of the electronic capsule layer located there will not enter the display state corresponding to the voltage difference between the second common electrode layer and the data lines, but will remain in a non-display state. This avoids abnormal image phenomena in the electronic ink screen corresponding to the second region, reduces or eliminates edge image abnormalities in the electronic ink screen, and improves the display effect of the electronic ink screen.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] In the description of this application, it is necessary to specify that, unless otherwise expressly stated and limited, the terms "installation," "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms within the context of this application.

[0026] This application first proposes an electronic ink display module, see [link to relevant documentation] Figure 1 , Figure 1 This is a side cross-sectional view of an embodiment of the electronic ink display module of this application, as shown in the figure. Figure 1 As shown, the electronic ink display module includes an array substrate 11, an insulating layer 12, a first common electrode layer 13, an electronic ink capsule layer 14, a second common electrode layer 15, and a driving module 16.

[0027] The array substrate 11 can be divided into a first region A1 and a second region A2. A plurality of thin-film field-effect transistors 111 disposed on the array substrate 11 can be located in the first region A1. Specifically, the thin-film field-effect transistors 111 can be disposed on the substrate 112 and located in the first region A1. The thin-film field-effect transistors 111 are connected to the data line 113 to receive corresponding data signals. In addition, the thin-film field-effect transistors 111 can be configured with corresponding pixel electrodes. By changing the voltage of the pixel electrode corresponding to each thin-film field-effect transistor 111, the voltage difference between the pixel electrode and the corresponding part of the second common electrode layer 15 can be changed, thereby enabling the display area corresponding to the first region in the electronic ink screen to display the image.

[0028] An insulating layer 12 is disposed on the array substrate 11 and located in the second region, and a first common electrode layer 13 is disposed on the side of the insulating layer 12 away from the array substrate 11. Specifically, the insulating layer can be used to isolate the first common electrode layer 13 and the data line 113 located in the second region on the array substrate 11, so that the two are insulated.

[0029] An electronic ink capsule layer 14 is disposed on one side of the second common electrode layer 15, and the electronic ink capsule layer 14 covers the first region and the first common electrode layer 13. Specifically, the electronic ink capsule layer 14 is disposed on the side of the second common electrode layer 15 near the array substrate 11. The electronic ink capsule layer 14 is disposed on the second common electrode layer 15. By covering the first region of the array substrate 11 and the side of the first common electrode layer 13 away from the array substrate 11 with the second common electrode layer 15 and the electronic ink capsule layer 14 disposed thereon, a portion of the electronic ink capsule layer 14 located in the first region can be sandwiched between the second common electrode layer 15 and the plurality of thin film field effect transistors 111, and another portion of the electronic ink capsule layer 14 located in the second region can be sandwiched between the second common electrode layer 15 and the first common electrode layer 13.

[0030] The data line 113 connected to each thin-film field-effect transistor 111 is connected to the driving module 16 through the second region to receive data signals. The first common electrode layer 13 and the second common electrode layer 15 are respectively connected to the driving module 16 to receive common electrode signals.

[0031] Based on the above method, the portion of the electronic ink capsule layer 14 located in the second region will not display a corresponding image due to the voltage difference between the data line 113 and the portion of the second common electrode layer 15 located in the second region. Instead, the portion of the electronic ink capsule layer 14 located in the second region will enter a non-display state because the first common electrode layer 13 and the second common electrode layer 15 both receive the same common electrode signal and there is no voltage difference. This prevents abnormal image display in the non-display area corresponding to the second region of the electronic ink screen, reduces or eliminates the abnormal image phenomenon at the edge of the electronic ink screen, and improves the display effect of the electronic ink screen.

[0032] Unlike existing technologies, the technical solution of this application divides the array substrate into a first region and a second region. Multiple thin-film field-effect transistors (TFTs) are located in the first region, and an insulating layer is disposed on the array substrate and located in the second region. A first common electrode layer is also disposed on the insulating layer. A second common electrode layer and an electronic ink capsule layer disposed on one side cover the first region and the first common electrode layer. The data lines connected to the TFTs pass through the second region and connect to the corresponding driving module. Based on this method, the insulating layer ensures insulation between the first common electrode layer and the data lines. Furthermore, by enabling the first and second common electrode layers to receive the common electrode signal from the driving module, there is no voltage difference between the portion of the second common electrode layer located in the second region and the first common electrode layer. Consequently, the portion of the electronic capsule layer located there will not enter the display state corresponding to the voltage difference between the second common electrode layer and the data lines, but will remain in a non-display state. This avoids image anomalies in the electronic ink screen corresponding to the second region, reduces or eliminates edge image anomalies in the electronic ink screen, and improves the display effect of the electronic ink screen.

[0033] In one embodiment, the projection of the insulating layer 12 onto the array substrate 11 at least partially overlaps with the projection of the data line 113 onto the array substrate 11.

[0034] Specifically, the larger the area of ​​the data line 113 projected onto the array substrate 11 by the projection of the insulating layer 12 onto the array substrate 11, the fewer the number of electronic ink capsules in the second region that are in an abnormal display state, that is, the weaker the abnormal display phenomenon at the edge of the electronic ink screen.

[0035] Optionally, the projection of the insulating layer 12 onto the array substrate 11 covers the entire projection of the data line 113 onto the array substrate 11 within the second region.

[0036] Specifically, by covering all the data lines 113 in the second region with the insulating layer 12, it can be ensured that the electronic ink capsules located in the second region of the electronic ink capsule layer 14 cannot receive the voltage signal of the data lines 113. Thus, even if there is a voltage difference between the data lines 113 and the second common electrode layer 15 in the second region, the voltage in the data lines 113 cannot affect any electronic ink capsule due to the presence of the insulating layer 12.

[0037] Based on the above methods, edge image abnormalities of e-ink screens can be reduced or eliminated as much as possible, thus improving the display effect of e-ink screens.

[0038] In one embodiment, the insulating layer 12 may be a SiNx layer or other types of non-conductive material layers, depending on the actual needs, and is not limited here.

[0039] Specifically, after the insulating layer 12 is grown on the array substrate 11, a conductive layer can be grown on the insulating layer 12 to form the first common electrode layer 13. The first common electrode layer 13 can be a copper layer or other conductive material layer, which can be determined according to actual needs and is not limited here.

[0040] In one embodiment, the array substrate 11 is divided into a first region, a second region, and a third region. The second region is sandwiched between the first region and the third region, and the driving module 16 is disposed in the third region.

[0041] Specifically, such as Figure 1 As shown, the second region A2 is sandwiched between the first region A1 and the third region A3. The driving module 16 can be located in the third region. The data line 113 crosses the second region A2 and the third region A3 to connect the thin film field effect transistor 111 and the driving module 16.

[0042] The driving module 16 can be used to transmit corresponding data signals to multiple thin-film field-effect transistors 111 via data line 113, so that the display area corresponding to the first area A1 in the electronic ink screen can display the image.

[0043] In one embodiment, a plurality of thin-film field-effect transistors 111 are arranged in an array, and a scan line connected to each thin-film field-effect transistor 111 is connected to a driving module 16 to receive the corresponding scan signal.

[0044] The driving module 16 can be used to send corresponding scanning signals to multiple thin-film field-effect transistors 111 through scanning lines, so that the display area corresponding to the first area A1 in the electronic ink screen can display the image.

[0045] In one embodiment, see Figure 2 , Figure 2This is a top view of an embodiment of the electronic ink display module of this application. The electronic ink display module also includes at least one connector 17, which is located in the second region A2.

[0046] The first common electrode layer 13 and the second common electrode layer 15 are respectively connected to a common line located on the array substrate 11 through corresponding connectors 17, and the common line is connected to the driving module 16.

[0047] Specifically, the first common electrode layer 13 and the second common electrode layer 15 can be connected to the common line located on the array substrate through the corresponding connectors 17. The common line can be connected to the driving module 16 to receive the corresponding common electrode signal.

[0048] The connectors 17 corresponding to the first common electrode layer 13 and the second common electrode layer 15 can be the same connector 17 or different connectors 17, depending on the actual needs, and are not limited here.

[0049] Alternatively, the connector may be made of silver paste or gold ball.

[0050] Optionally, the first common electrode layer 13 and the second common electrode layer 15 are connected to a common line located on the array substrate 11 via the same connector 17, and the common line is connected to the driving module 16.

[0051] Specifically, a connector 17 can be connected to the first common electrode layer 13 and the second common electrode layer 15 respectively, so that the first common electrode layer 13 and the second common electrode layer 15 are short-circuited. Then, the connector 17 is connected to the driving module to receive the corresponding common electrode signal, thereby making the voltage signals on the first common electrode layer 13 and the second common electrode layer 15 the same, ensuring that there is no voltage difference between them, further avoiding the display abnormality of the electronic ink capsule in the second region, and improving the reliability of the electronic ink display module.

[0052] This application also proposes a display panel, see [link to relevant documentation] Figure 3 , Figure 3 This is a schematic diagram of the structure of one embodiment of the display panel of this application, as shown below. Figure 3 As shown, the display panel 20 includes a power module 21 and an electronic ink display module 22, which may include the electronic ink display module described in any of the preceding embodiments.

[0053] Unlike existing technologies, the technical solution of this application divides the array substrate into a first region and a second region. Multiple thin-film field-effect transistors (TFTs) are located in the first region, and an insulating layer is disposed on the array substrate and located in the second region. A first common electrode layer is also disposed on the insulating layer. A second common electrode layer and an electronic ink capsule layer disposed on one side cover the first region and the first common electrode layer. The data lines connected to the TFTs pass through the second region and connect to the corresponding driving module. Based on this method, the insulating layer ensures insulation between the first common electrode layer and the data lines. Furthermore, by enabling the first and second common electrode layers to receive the common electrode signal from the driving module, there is no voltage difference between the portion of the second common electrode layer located in the second region and the first common electrode layer. Consequently, the portion of the electronic capsule layer located there will not enter the display state corresponding to the voltage difference between the second common electrode layer and the data lines, but will remain in a non-display state. This avoids image anomalies in the electronic ink screen corresponding to the second region, reduces or eliminates edge image anomalies in the electronic ink screen, and improves the display effect of the electronic ink screen.

[0054] This application also proposes a method for manufacturing an electronic ink display module, see [link to application]. Figure 4 , Figure 4 This is a schematic flowchart of one embodiment of the method for manufacturing an electronic ink display module according to this application, such as... Figure 4 As shown, the manufacturing method includes:

[0055] Step S11: Generate the array substrate.

[0056] The array substrate 11 is divided into a first region A1 and a second region A2. A plurality of thin-film field-effect transistors 111 are disposed in the first region A1. Data lines 113 connected to each thin-film field-effect transistor 111 are connected to the corresponding driving module 16 through the second region to receive data signals.

[0057] For example, see Figure 5 , Figure 5 This is a second schematic flowchart of an embodiment of the method for manufacturing an electronic ink display module according to this application, as shown below. Figure 5 As shown in (A), an array substrate 11 with a plurality of thin-film field-effect transistors 111 disposed on a substrate 112 can be generated, and a data line 113 connected to each thin-film field-effect transistor 111 passes through a second region A2.

[0058] Step S12: An insulating layer is formed on the second region of the array substrate.

[0059] For example, Figure 5 As shown in (B), an insulating layer 12 for isolating voltage can be formed on the second region A2.

[0060] Step S13: Form a first common electrode layer on the insulating layer.

[0061] For example, Figure 5 As shown in (C), a first common electrode layer 13 can be formed on the insulating layer 12.

[0062] Step S14: A second common electrode layer is formed on the first region of the array substrate and on the first common electrode layer.

[0063] Among them, an electronic ink capsule layer 14 is provided on one side of the second common electrode layer 15, and the electronic ink capsule layer 14 covers the first region A1 and the first common electrode layer 13.

[0064] The first common electrode layer 13 and the second common electrode layer 15 are respectively connected to the driving module 16 to receive the common electrode signal.

[0065] After the electronic ink capsule layer 14 is disposed on one side of the second common electrode layer 15, the electronic ink capsule layer 14 and the second common electrode layer 15 to which it is attached are then bonded together to the array substrate 11 and the first common electrode layer 13.

[0066] Specifically, in one example, the construction process of the above-mentioned electronic ink display module can be as follows:

[0067] The first step is to generate a plurality of thin-film field-effect transistors 111 located in the first region A1 and data lines 113 located in the second region A2 and the third region A3 on the substrate 112.

[0068] The second step is to form an insulating layer 12 on the second region A2, and then form a first common electrode layer 13 on the insulating layer 12.

[0069] The third step is to clean the array substrate 11 and its insulating layer 12 and first common electrode layer 13.

[0070] The fourth step is to generate the second common electrode layer 15 and the electronic ink capsule layer 14 disposed on one side thereon, as well as the adhesive sticker on the side of the electronic ink capsule layer 14 near the array substrate 11.

[0071] Fifth step, the connector 17 is generated on the portion of the electronic ink capsule layer 14 located in the second region.

[0072] Step 6: Clean the electronic ink capsule layer 14.

[0073] Step 7: Remove the adhesive sticker from the electronic ink capsule layer 14.

[0074] The eighth step involves attaching the second common electrode layer 15 and the electronic ink capsule layer 14 disposed on one side of it to the array substrate 11 and the first common electrode layer 13 respectively, and then hot-pressing them to form the target module.

[0075] It should be noted that steps one through three and steps four through seven are parallel steps with no fixed order, but all must be completed before step eight. Steps one through three are specific example steps corresponding to steps S11 through S13, while steps four through seven are specific example steps corresponding to step S14.

[0076] The ninth step involves constructing external circuitry (such as COG / FOG / FPC) on the target module and encapsulating the target module with adhesive to form an electronic ink display module.

[0077] The tenth step is to perform fault detection on the e-ink display module to ensure that there are no quality problems before it can be used by the user.

[0078] Unlike existing technologies, the technical solution of this application divides the array substrate into a first region and a second region. Multiple thin-film field-effect transistors (TFTs) are located in the first region, and an insulating layer is disposed on the array substrate and located in the second region. A first common electrode layer is also disposed on the insulating layer. A second common electrode layer and an electronic ink capsule layer disposed on one side cover the first region and the first common electrode layer. The data lines connected to the TFTs pass through the second region and connect to the corresponding driving module. Based on this method, the insulating layer ensures insulation between the first common electrode layer and the data lines. Furthermore, by enabling the first and second common electrode layers to receive the common electrode signal from the driving module, there is no voltage difference between the portion of the second common electrode layer located in the second region and the first common electrode layer. Consequently, the portion of the electronic capsule layer located there will not enter the display state corresponding to the voltage difference between the second common electrode layer and the data lines, but will remain in a non-display state. This avoids image anomalies in the electronic ink screen corresponding to the second region, reduces or eliminates edge image anomalies in the electronic ink screen, and improves the display effect of the electronic ink screen.
