[0042] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0043] Figure 1 This is a side view of a display device according to an embodiment of the present invention. The display device 10 includes a driving substrate 12, an electronic ink layer 14, a touch layer 16, and a cover plate 18. The driving substrate 12 may include a carrier substrate and driving circuit elements disposed on the carrier substrate, and is used to provide driving signals to the electronic ink layer 14 to realize the display function. The electronic ink layer 14 is disposed on the driving substrate 12. The touch layer 16 can be attached to the electronic ink layer 14 to provide touch operation function for the display device 10. The cover plate 18 is attached to the touch layer 16 and located on the outside of the display device 10 to provide protection and increase the strength of the device. In some embodiments, the touch layer 16 may be omitted, and the cover plate 18 may be directly attached to the electronic ink layer 14. In some embodiments, a bottom protective plate may be additionally attached to the side of the driving substrate 12 away from the electronic ink layer 14 to increase the mechanical strength of the display device 10.

[0044] The display device 10 is a reflective display device. Specifically, the electronic ink material in the electronic ink layer 14 has the characteristic of reflecting external light, and the electronic ink material can reflect external light to a specified degree under the driving electric field provided by the driving substrate 12, thereby achieving a display effect. In this embodiment, the electronic ink layer 14 has a built-in light source structure LS, and the built-in light source structure LS can be located between the electronic ink material and the outside world. When the display device 10 displays an image, the light provided by the built-in light source structure LS can illuminate the electronic ink material for display purposes. Therefore, when the external light is weak, the display device 10 can use the light provided by the light source structure LS to maintain sufficient display brightness. In other words, the built-in light source structure LS helps to optimize the display effect of the display device 10. In addition, the built-in light source structure LS is directly built into the electronic ink layer 14, or disposed on the electronic ink layer 14 by bonding or other means. Therefore, the built-in light source structure LS helps to make the display device 10 have a compact device size, which helps to improve the application flexibility of the display device 10.

[0045] For ease of explanation, the following description, accompanied by accompanying drawings, will illustrate various embodiments of the electronic ink layer with a built-in light source structure, without describing other components in the display device in detail. It will be apparent that the electronic ink layer in the following individual embodiments can serve as... Figure 1 Possible implementations of the electronic ink layer 14 are described, but are not limited thereto.

[0046] Figure 2 This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. The electronic ink layer 100 includes an encapsulation structure 110, electronic ink material 120, a light source structure 130, and a plurality of light-shielding patterns 140. The encapsulation structure 110 includes a separating member 112, a first encapsulation layer 114, and a second encapsulation layer 116. The first encapsulation layer 114 covers the separating member 112. The separating member 112 encloses a plurality of encapsulation spaces 112U, and the electronic ink material 120 fills the plurality of encapsulation spaces 112U to form a plurality of display units 102. The second encapsulation layer 116 is located on opposite sides of the separating member 112 to seal the display units 102 therebetween. The light source structure 130 is disposed on the first encapsulation layer 114. The plurality of light-shielding patterns 140 are disposed on the side of the light source structure 130 away from the display units 102. Here, the separating member 112 is, for example, a microcup structure, and individual display units 102 may be constituted by electronic ink material 120 in individual encapsulation spaces 112U.

[0047] The electronic ink material 120 includes display particles 122 and a matrix 124 for dispersing the display particles 122. In some embodiments, at least a portion of the display particles 122 have light-reflective properties, and the display particles 122 can migrate within the matrix 124 under the influence of an electric field to present different distribution states. Thus, display particles 122 with different distribution states can provide different degrees of light reflection to display an image. In some embodiments, the display particles 122 may include color display particles adapted to reflect different colors.

[0048] The light source structure 130 is directly fabricated on the first encapsulation layer 114 and integrated into the electronic ink layer 100. In other words, the light source structure 130 is not attached to the first encapsulation layer 114 by bonding, fastening, or other joining methods. In some embodiments, the light source structure 130 can be fabricated on the first encapsulation layer 114 by printing, coating, or similar alternative methods. Therefore, the electronic ink layer 100 integrating the light source structure 130 can achieve a design that provides its own light source without significantly increasing its size.

[0049] Specifically, the light source structure 130 includes a first electrode structure 132, a second electrode structure 134, a plurality of light-emitting units 136, and a planarization layer 138. The light-emitting units 136 are disposed between the first electrode structure 132 and the second electrode structure 134, and are located between the first encapsulation layer 114 and the plurality of light-shielding patterns 140. The planarization layer 138 is disposed between the first electrode structure 132 and the second electrode structure 134, and laterally contacts the light-emitting units 136. Both the planarization layer 138 and the light-emitting units 136 can be disposed on the upper surface T132 of the first electrode structure 132, and the upper surface T138 of the planarization layer 138 and the upper surface T136 of the light-emitting units 136 are coplanar. Thus, the second electrode structure 134 can be formed on the common plane of the upper surface T138 of the planarization layer 138 and the upper surface T136 of the light-emitting units 136.

[0050] The first electrode structure 132, the second electrode structure 134, the light-emitting unit 136, the planarization layer 138, and the light-shielding pattern 140 can be formed on the surface of the first encapsulation layer 114 by printing or coating the corresponding materials in a desired layout. Figure 2 In this embodiment, both the first electrode structure 132 and the second electrode structure 134 are structures that extend continuously between and in contact with the multiple light-emitting units 136. They can be planar layer structures, but this is not an example of the present invention. In some embodiments, at least one of the first electrode structure 132 and the second electrode structure 134 may be a strip structure in the top view. The materials of the first electrode structure 132 and the second electrode structure 134 may include transparent conductive materials, allowing light emitted by the light-emitting units 136 to pass through.

[0051] The light-emitting unit 136 can be made of organic light-emitting material, which can be formed on the first electrode structure 132 by printing. In some embodiments, the light-emitting unit 136 may include a stacked first-color light-emitting layer 136A, a second-color light-emitting layer 136B, and a third-color light-emitting layer 136C. The light emitted by the first-color light-emitting layer 136A, the second-color light-emitting layer 136B, and the third-color light-emitting layer 136C includes red light, green light, and blue light. In other words, the light-emitting unit 136 is composed of a stacked structure of a red light-emitting layer, a green light-emitting layer, and a blue light-emitting layer. The stacking order of the red light-emitting layer, the green light-emitting layer, and the blue light-emitting layer of the light-emitting unit 136 can be adjusted according to different needs and is not limited to a specific order. In addition, the thickness of the red light-emitting layer, the green light-emitting layer, and the blue light-emitting layer in the light-emitting unit 136 can also be adjusted according to the characteristics of the light-emitting material, the desired light emission effect, and other factors. In other embodiments, the light-emitting unit 136 may be composed of two stacked light-emitting layers, or may be composed of one or more light-emitting layers combined with a light conversion material (e.g., quantum dots). The light-emitting unit 136 as a whole can be used to emit white light, but is not limited thereto. In some embodiments, different light-emitting units 136 can emit light of different colors.

[0052] The electronic ink layer 100 uses reflective display technology for display. Therefore, only the portion of the light from the light source structure 130 that travels towards the display unit 102 is effectively used as display light. The portion of the light from the light source structure 130 that travels away from the display unit 102 may affect the user's viewing quality, such as causing glare. Therefore, a light-shielding pattern 140 is provided above each light-emitting unit 136 to block light emitted directly to the outside. The light-shielding pattern 140 can directly contact the upper surface T134 of the second electrode structure 134 and overlaps the area of ​​the light-emitting unit 136.

[0053] The position of the light-emitting unit 136 can be adjusted according to different needs, and Figure 2 The explanation is based on the premise that the light-emitting unit 136 is located above the separating member 112. Generally, the area of ​​the display unit 102 is the actual display area that can display images, while the area of ​​the separating member 112 is the area that does not display images. Since the light-emitting unit 136 is located above the separating member 112, the light-blocking pattern 140 is also located above the separating member 112 and will not block the display area, which helps to maintain the size of the display area.

[0054] Figure 3 This is a partial top view of the electronic ink layer according to an embodiment of the present invention. Figure 3 The electronic ink layer 200 can be applied to Figure 1 The display device 10 is used as one embodiment of the electronic ink layer 14. Additionally, Figure 3 The presented structure can also be Figure 2One embodiment of the electronic ink layer 100 as viewed from above. For ease of explanation, Figure 3 The diagram shows that the electronic ink layer 200 includes a display unit 202, a packaging structure 210 (only the separating member 212 is shown), and a light source structure 230. However, the electronic ink layer 200 may also include other components. Figure 3 Omitted structures, for example Figure 2 The first encapsulation layer 114, the second encapsulation layer 116, and the light-shielding pattern 140 are included. Additionally, the display unit 202 can correspond to... Figure 2 In one embodiment of the display unit 102 in a top view, the partition member 212 may correspond to Figure 2 In one embodiment of the partition member 112 in the top view, the light source structure 230 may correspond to... Figure 2 One embodiment of the light source structure 130 in a top view.

[0055] exist Figure 3 In the top view, the partition member 212 has multiple linear segments L212 extending in different directions, and these linear segments L212 intersect each other. For example, these linear segments L212 can enclose hexagonal regions as enclosing spaces 212U, and have a honeycomb-like shape. These enclosing spaces 212U are arranged adjacent to each other to define multiple display units 202. In other embodiments, the linear segments L212 can extend in only two directions to enclose multiple quadrilateral regions. Alternatively, the linear segments L212 can extend in three or more directions to enclose regions of various geometries.

[0056] The light source structure 230 includes a first electrode structure 232, a second electrode structure 234, and a plurality of light-emitting units 236. The first electrode structure 232 and the second electrode structure 234 may be disposed along the separating member 212 and extend continuously between the plurality of light-emitting units 236. Figure 2 As can be seen from the cross-sectional structural design, the first electrode structure 232 and the second electrode structure 234 are located at different layers but can overlap each other in the top view. Therefore, the first electrode structure 232 and the second electrode structure 234 are in Figure 3 The light-emitting units 236 are all marked in the same pattern. In the top view, these light-emitting units 236 are all located above the separating member 212, and multiple light-emitting units 236 can contact the first electrode structure 232 and the second electrode structure 234. The light-emitting units 236 may be located at the intersection point C212 where the linear segments L212 of the separating member 212 intersect, but are not limited thereto. In some embodiments, the light-emitting units 236 may be located on the linear segment L212 of the separating member 212. In addition, the distribution density of the light-emitting units 236 may be adjusted according to different designs.

[0057] Although the light-emitting unit 236 is as shown in the cross-sectional structure Figure 2The light-emitting unit 136 is generally disposed between the first electrode structure 232 and the second electrode structure 234, but for ease of explanation... Figure 3 The light-emitting unit 236 is drawn directly. Alternatively, the light-emitting unit 236 can be drawn as follows: Figure 2 The light-emitting unit 136 is implemented by multiple light-emitting layers or by combining light-emitting layers with light-converting materials. The light-emitting unit 236 is, for example, an organic light-emitting diode (OLED), and individual light-emitting layers can be fabricated by printing. The light-emitting unit 236 emits white light under the driving current provided by the first electrode structure 232 and the second electrode structure 234, for use by the display unit 202. In this embodiment, the area occupied by the separating member 212 is an area that does not originally provide a display function. The light source structure 230 is positioned along the separating member 212 without obstructing the display unit 202. Therefore, the material of the light source structure 230 does not need to be limited to transparent materials. In other words, the first electrode structure 232, the second electrode structure 234, and the light-emitting unit 236 can be made of either transparent or opaque materials.

[0058] In other embodiments, such as Figure 4 As shown in the electronic ink layer 200', the light-emitting units 236 of the light source structure 230 are configured to overlap the display unit 202. The electronic ink layer 200' includes the display unit 202, the encapsulation structure 210 (only the separating member 212 is shown), and the light source structure 230. In this embodiment, the first electrode structure 232 and the second electrode structure 234 may each include multiple electrode lines, and individual electrode lines may contact several light-emitting units 236. The light-emitting units 236 are located above the encapsulation space 212U surrounded by the separating member 212 and overlap the display unit 202. That is, the light-emitting units 236 are located within the display area of ​​the display unit 202. The electrode lines of the first electrode structure 232 and the second electrode structure 234 extend across multiple display units 202. The light-emitting units 236 and the electrode lines of the first electrode structure 232 and the second electrode structure 234 may be made of transparent material to reduce the degree to which the light source structure 230 blocks the display light. However, since the light source structure 230 can provide light for display and help improve display brightness, when the light source structure 230 is configured as an overlay display unit 202, it is not limited to using a transparent material to make the light source structure 230.

[0059] Figures 5 to 6 This is a schematic diagram showing the arrangement of the light source structure and the separating components in the electronic ink layer of different embodiments of the present invention from a top-view perspective. Figure 5 The electronic ink layer 300A includes a packaging structure 210, electronic ink material, a light source structure 330, and multiple light-shielding patterns. (For ease of explanation...) Figure 5The diagram primarily shows the separator 212 of the encapsulation structure 210 and the second electrode structure 334 and multiple light-emitting units 336 of the light source structure 330, while other components are omitted. In some embodiments, the electronic ink layer 300A may further include... Figure 2 The electronic ink material 120 and the light-shielding pattern 140 shown, and the packaging structure 210 may also include Figure 2 The first encapsulation layer 114 and the second encapsulation layer 116 are shown. Additionally, the first electrode structure in the light source structure 330 can be implemented using a full-surface electrode layer and is therefore not shown. Figure 5 However, this is not the only applicable measure. Specifically, Figure 5 It is mainly used to illustrate the arrangement relationship between the separating member 212, the second electrode structure 334 and the light-emitting unit 336, but not to limit the electronic ink layer 300A to these members.

[0060] In this embodiment, the layout design of the partition member 212 can be referred to Figure 3 The relevant explanation is as follows. The light-emitting unit 336 includes, for example, a first light-emitting unit 336A, a second light-emitting unit 336B, and a third light-emitting unit 336C. ​​The first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C are arranged spaced apart from each other and provide different colors of light. The individual colors of light emitted by the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C can, for example, be mixed to form white light. Figure 5 In this configuration, the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C can be dispersedly arranged along the linear segment L212 of the separating member 212. For example, the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C can be dispersedly arranged on the lower right side of three display units 202A to 202C arranged in the same row direction C, but this is not a limitation.

[0061] The second electrode structure 334 may include multiple independent electrode lines, such as a first electrode line 334A, a second electrode line 334B, and a third electrode line 334C. The first electrode line 334A can contact and be electrically connected to the first light-emitting unit 336A, the second electrode line 334B can contact and be electrically connected to the second light-emitting unit 336B, and the third electrode line 334C can contact and be electrically connected to the third light-emitting unit 336C. ​​The first electrode line 334A, the second electrode line 334B, and the third electrode line 334C can operate independently to drive light-emitting units 336 of different colors respectively. Figure 5As shown, each of the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C can extend along one of the linear segments L212 of the separating member 212. The first electrode line 334A, the second electrode line 334B, and the third electrode line 334C can be parallel to each other. The first electrode line 334A, the second electrode line 334B, and the third electrode line 334C may extend across the display unit 202, but the invention is not limited thereto.

[0062] Figure 6 The electronic ink layer 300B is similar to Figure 5 The electronic ink layer 300A has a configuration of the separator 212, the second electrode structure 334, and the light-emitting unit 336. The light-emitting unit 336 includes a first light-emitting unit 336A, a second light-emitting unit 336B, and a third light-emitting unit 336C. ​​Each first light-emitting unit 336A and one of the second light-emitting units 336B are disposed on opposite sides of a corresponding display unit 202, and each second light-emitting unit 336B and one of the third light-emitting units 336C are disposed on opposite sides of another corresponding display unit 202.

[0063] Furthermore, the second electrode structure 334 includes a first electrode line 334A, a second electrode line 334B, and a third electrode line 334C. In this embodiment, the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C are arranged substantially entirely along the separating member 212. Therefore, none of the first electrode lines 334A, the second electrode line 334B, or the third electrode line 334C extend beyond the display unit 202. Additionally, the first electrode lines 334A, the second electrode line 334B, and the third electrode line 334C are arranged side-by-side without intersecting or overlapping.

Figure 7 The light source structure 330 can be applied to Figure 1 The display device 10 is implemented as one embodiment of the built-in light source structure LS in the electronic ink layer 14. Additionally, Figure 7 The presented structure can also be Figure 2 The light source structure 130 in the electronic ink layer 100 and Figure 5 and Figure 6 One embodiment of the light source structure 330. For example...

Additionally, Figure 7 The light-shielding pattern 140 is also shown, for example, the light-shielding pattern 140 is set on the light source structure 330 and located above the individual light-emitting units 336.

[0065] To explain further, Figure 7 Only the first electrode line 334A and the second electrode line 334B of the second electrode structure 334 are shown, and only the first light-emitting unit 336A and the second light-emitting unit 336B of the light-emitting unit 336 are shown. Specifically, the first light-emitting unit 336A and the second light-emitting unit 336B emit different colors of light, and the layout design of the first light-emitting unit 336A and the second light-emitting unit 336B in the top view can be referred to Figure 5 or Figure 6 This can be implemented in various ways, but is not limited to this. Furthermore, Figure 7 Although the cross-sectional structure is not shown Figure 5 and Figure 6 The third light-emitting unit 336C and the third electrode line 334C are in the same design, but the third light-emitting unit 336C and the third electrode line 334C can be implemented in the same way.

[0066] exist Figure 7 In this structure, the first electrode structure 132 extends continuously from and contacts the first light-emitting unit 336A and the second light-emitting unit 336B. A planarization layer 138 is sandwiched between the first electrode structure 132 and the second electrode structure 334. Specifically, both the planarization layer 138 and the first light-emitting unit 336A are disposed on the first electrode structure 132, and the thickness of the planarization layer 138 is designed to expose the upper surfaces T336A of the first light-emitting unit 336A and the second light-emitting unit 336B. The first electrode line 334A and the second electrode line 334B can contact the upper surfaces T336A of the first light-emitting unit 336A and the second light-emitting unit 336B. Thus, the first electrode line 334A and the second electrode line 334B... Figure 7 The same conductive layer site exists in the middle, but... Figure 5 and Figure 6 The first electrode line 334A and the second electrode line 334B are arranged independently side by side, so that the first light-emitting unit 336A and the second light-emitting unit 336B can provide different driving currents. Therefore, the luminous intensity of the first light-emitting unit 336A and the second light-emitting unit 336B can be independently controlled to achieve the requirement of adjusting the color temperature.

[0067] Figures 8 to 9This is a schematic diagram showing the arrangement of the light source structure and the separating components in the electronic ink layer of several embodiments of the present invention from a top-view perspective. Figure 8 The electronic ink layer 400A includes a packaging structure 210, electronic ink material, a light source structure 430, and multiple light-shielding patterns. (For ease of explanation...) Figure 8 The diagram primarily shows the partition member 212 of the encapsulation structure 210 and the second electrode structure 434 and multiple light-emitting units 336 of the light source structure 430, while other components are omitted. In some embodiments, the electronic ink layer 400A may further include... Figure 2 The electronic ink material 120 and the light-shielding pattern 140 shown, and the packaging structure 210 may also include Figure 2 The first encapsulation layer 114 and the second encapsulation layer 116 are shown. Therefore, Figure 8 It is mainly used to illustrate the arrangement relationship between the separator 212, the second electrode structure 434 and the light-emitting unit 336, but not to limit the electronic ink layer 400A to these components.

[0068] Figure 8 The arrangement of the separator 212, the second electrode structure 434, and the light-emitting unit 336 in the electronic ink layer 400A is shown. The light-emitting unit 336 includes a first light-emitting unit 336A, a second light-emitting unit 336B, and a third light-emitting unit 336C, which are dispersedly disposed on the linear segment L212 of the separator 212. For example, one of the first light-emitting units 336A, one of the second light-emitting units 336B, and one of the third light-emitting units 336C may be concentrated near one intersection point C212 of the linear segment L212. The proximity of the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C helps to improve the mixing effect of different colors of light.

[0069] exist Figure 8 In this structure, the second electrode structure 434 includes a first electrode line 434A, a second electrode line 434B, and a third electrode line 434C. These three electrode lines are respectively in contact with and electrically connected to the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C. ​​The first electrode line 434A, the second electrode line 434B, and the third electrode line 434C can be parallel to each other and extend approximately along the row direction C. Thus, the first electrode line 434A, the second electrode line 434B, and the third electrode line 434C may extend above the light-emitting unit 336, but are not limited to this. Furthermore, the first electrode line 434A, the second electrode line 434B, and the third electrode line 434C can intersect each other.

[0070] Figure 9 The electronic ink layer 400B is similar to Figure 8 The electronic ink layer 400A has a configuration of the separator 212, the second electrode structure 434, and the light-emitting unit 336. The light-emitting unit 336 includes a first light-emitting unit 336A, a second light-emitting unit 336B, and a third light-emitting unit 336C. ​​The first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C are dispersedly disposed on the linear segment L212 of the separator 212. The second electrode structure 434 includes a first electrode line 434A, a second electrode line 434B, and a third electrode line 434C, which are disposed along the separator 212.

[0071] In this embodiment, one of the second light-emitting units 336B and one of the third light-emitting units 336C are disposed on a linear segment L212 adjacent to one of the first light-emitting units 336A, such that the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C are disposed close to each other, which helps to improve the mixing effect of different colors of light. In addition, the first electrode line 434A, the second electrode line 434B, and the third electrode line 434C do not cross the top of the display unit 202, and the first electrode line 434A, the second electrode line 434B, and the third electrode line 434C can partially overlap along the linear segment L212.

[0072] Figure 10 This is a partial cross-sectional schematic diagram of a light source structure according to an embodiment of the present invention. Figure 10 The light source structure 430 can be applied to Figure 1 The display device 10 is implemented as one embodiment of the built-in light source structure LS in the electronic ink layer 14. Additionally, Figure 10 The structure shown can be used as Figure 8 and Figure 9 One embodiment of the cross-sectional structure of the light source structure 430. For ease of explanation, Figure 10 The above is the main content. Figure 8 and Figure 9 The relationship between two light-emitting units 336 (first light-emitting unit 336A and second light-emitting unit 336B) and other components in the embodiment.

[0073] Specifically, the light source structure 430 includes a first electrode structure 132, a second electrode structure 434, multiple light-emitting units 336, and a planarization layer 438, wherein the first electrode structure 132 can be referred to as Figure 2The relevant explanation is as follows: Both the first light-emitting unit 336A and the second light-emitting unit 336B are disposed on the first electrode structure 132, and the first light-emitting unit 336A and the second light-emitting unit 336B are used to emit different colors of light. The first electrode structure 132, for example, extends continuously between the first light-emitting unit 336A and the second light-emitting unit 336B and contacts the first light-emitting unit 336A and the second light-emitting unit 336B.

[0074] The second electrode structure 434 includes multiple electrode lines, and these electrode lines contact different portions of the multiple light-emitting units 336. For example, Figure 10 The diagram shows a second electrode structure 434, including a first electrode line 434A contacting the first light-emitting unit 336A and a second electrode line 434B contacting the second light-emitting unit 336B. The first electrode line 434A and the second electrode line 434B are independent of each other; therefore, the first light-emitting unit 336A and the second light-emitting unit 336B can emit light under different driving currents, thus achieving adjustment of the emission color temperature. Figure 10 As shown, the first electrode line 434A and the second electrode line 434B are located at different conductive layer sites Mx and My, and the planarization layer 438 may include multiple layers to separate the different conductive layer sites Mx and My. Thus, the first electrode line 434A and the second electrode line 434B may intersect or overlap in the top view direction, but they do not contact each other and can provide independent electrical transmission paths.

[0075] Planarization layer 438 may include a first planarization layer 438A, a second planarization layer 438B, and a third planarization layer 438C. The first planarization layer 438A laterally surrounds a portion of the first light-emitting unit 336A and the second light-emitting unit 336B. A first electrode line 434A formed by conductive layer sites Mx may be disposed on the first planarization layer 438A. The second planarization layer 438B laterally surrounds the second light-emitting unit 336B. A second electrode line 434B formed by conductive layer sites My may be disposed on the second planarization layer 438B. The third planarization layer 438C covers the second electrode line 434B formed by conductive layer sites My. The thickness of the first planarization layer 438A may be set such that the upper surface T336A of the first light-emitting unit 336A is exposed, allowing the first electrode line 434A to contact the first light-emitting unit 336A. Similarly, the thickness of the second planarization layer 438B may be set such that the upper surface T336B of the second light-emitting unit 336B is exposed, allowing the second electrode line 434B to contact the second light-emitting unit 336B. Additionally, the thickness of the third planarization layer 438C may cover the second electrode line 434B, but is not limited thereto. In some embodiments, the light source structure 430 may further include... Figure 8 and Figure 9The third light-emitting unit 336C described herein, and the second electrode structure 434 may further include a third electrode line 434C corresponding to the third light-emitting unit 336C, wherein the third electrode line 434C may be located in other conductive layers, and the planarization layer 438 may include an additional planarization layer.

[0076] Figure 11 This is a schematic diagram showing the arrangement of the light source structure and the separating member in the electronic ink layer according to an embodiment of the present invention, viewed from above. Figure 11 The electronic ink layer 500 includes an encapsulation structure 210, electronic ink material, a light source structure 330, and multiple light-shielding patterns. For ease of explanation, Figure 11 The main focus is on the partition member 212 of the encapsulation structure 210 and the second electrode structure 334 and multiple light-emitting units 336 of the light source structure 330, while other components are omitted. Additionally, Figure 11 A portion of the peripheral circuitry 550 of the light source structure 330 is further shown, and the peripheral circuitry 550 is connectable to the second electrode structure 334. In some embodiments, the electronic ink layer 500 may further include... Figure 2 The electronic ink material 120 and the light-shielding pattern 140 shown, and the packaging structure 210 may also include Figure 2 The first encapsulation layer 114 and the second encapsulation layer 116 are shown. Therefore, Figure 11 It is mainly used to illustrate the arrangement relationship between the separator 212, the second electrode structure 334 and the light-emitting unit 336, but not to limit the electronic ink layer 500 to these components.

[0077] In this embodiment, the layout design of the partition member 212 is similar to... Figure 3 The embodiments are the same, and the separating member 212 can define multiple display units 202. The light-emitting unit 336 includes a first light-emitting unit 336A, a second light-emitting unit 336B, and a third light-emitting unit 336C. ​​Each of the first light-emitting unit 336A, second light-emitting unit 336B, and third light-emitting unit 336C is disposed within the display area of ​​the display unit 202. The first light-emitting unit 336A is arranged in a column along the column direction R, the second light-emitting unit 336B is arranged in a column along the column direction R, and the third light-emitting unit 336C is arranged in a column along the column direction R. The first light-emitting unit 336A, second light-emitting unit 336B, and third light-emitting unit 336C are located in different columns. The second electrode structure 334 includes a first electrode line 334A, a second electrode line 334B, and a third electrode line 334C. Each of the first electrode line 334A, second electrode line 334B, and third electrode line 334C extends along the column direction R and crosses over the multiple display units 202. The first electrode line 334A, the second electrode line 334B, and the third electrode line 334C extend in different columns.

[0078] The peripheral line 550 may include a first signal line 552, a second signal line 554, and a third signal line 556. The first signal line 552 connects to the first electrode line 334A, the second signal line 554 connects to the second electrode line 334B, and the third signal line 556 connects to the third electrode line 334C. The first signal line 552, the second signal line 554, and the third signal line 556 each extend along the row direction C, connecting their corresponding electrode lines together. Therefore, the first signal line 552, the second signal line 554, and the third signal line 556 will intersect with the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C.

[0079] In this embodiment, the light source structure 330 may adopt... Figure 7 The described method is used to implement the cross-sectional design of its individual components. Thus, the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C are arranged side-by-side on the same layer. Therefore, the intersection point C550 where the first signal line 552, the second signal line 554, and the third signal line 556 intersect at the intersection of the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C can employ a multi-conductive layer structure to avoid short-circuiting between these lines.

[0080] In some alternative embodiments, the second electrode line 334B may be employed. Figure 10 The cross-sectional design is implemented using the described second electrode line 434B. Thus, the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C can be implemented using... Figure 10 The first electrode line 434A, the second electrode line 434B, and the third electrode line 434C are implemented in a manner located at different conductive layers. Similarly, the first signal line 552, the second signal line 554, and the third signal line 556 can also be located at different conductive layers. Therefore, although the first signal line 552, the second signal line 554, and the third signal line 556 intersect with the first electrode line 334A, the second electrode line 334B, and the third electrode line 334C, they do not contact each other and remain electrically independent.

[0081] Figure 12 This is a partial cross-sectional schematic diagram of the light source structure in the electronic ink layer according to an embodiment of the present invention. Figure 12 The cross-sectional structure is used to illustrate Figure 11 This is one implementation of the central light source structure 330 and the surrounding circuitry 550, but it is not limited thereto. Specifically, Figure 12 The cross-sectional structure mainly presents the light source structure 330 and above. Figure 7 When implementing its cross-sectional structure in this manner, the possible implementation methods of the corresponding peripheral lines 550 are as follows. Therefore, it can be referred to... Figure 7 To understand from the explanation Figure 12The design. Specifically. Figure 12 The light source structure 330 includes a first electrode structure 132, a second electrode structure 334, a light-emitting unit 336, and a planarization layer 138. The first electrode structure 132 and the second electrode structure 334 are disposed on opposite sides of the planarization layer 138, and the planarization layer 138 laterally surrounds the light-emitting unit 336. Meanwhile, Figure 12 The intersection point C550 of the third signal line 556 of the peripheral line 550 and the first electrode line 334A of the second electrode structure 334 is shown.

[0082] like Figure 12 As shown, the planarization layer 138 may have a recess C138 at the intersection C550, and the first electrode line 334A of the second electrode structure 334 may extend in accordance with the undulation of the recess C138. An additional separator material 558 may be disposed at the intersection C550 and cover the first electrode line 334A in the recess C138. The third signal line 556 of the peripheral line 550 is disposed on the separator material 558. Thus, the separator material 558 can separate the third signal line 556 of the peripheral line 550 from the first electrode line 334A of the second electrode structure 334, maintaining their electrical independence. The material of the separator material 558 may be the same as that of the planarization layer 138, or it may be another conductive material.

In addition to the aforementioned components, the electronic ink layer 600 may also include... Figure 2 The electronic ink material 120, the light-shielding pattern 140, and the first encapsulation layer 114 and the second encapsulation layer 116 of the encapsulation structure 210 are shown.

[0084] In this embodiment, the layout design of the partition member 212 is similar to... Figure 3 The embodiments are the same, and the separating member 212 can define a plurality of display units 202, wherein each display unit 202 is filled with Figure 2The electronic ink material 120 shown is illustrated. The separating member 212, in a top view, may include multiple linear segments L212 extending in different directions, and these linear segments L212 may intersect at an intersection point C212. This embodiment illustrates the use of linear segments L212 to enclose a hexagonal region to define the display unit 202, but this is not a limitation. In other embodiments, the linear segments L212 may enclose regions of different geometries to define the display unit 202.

[0085] The light-emitting unit 336 includes a first light-emitting unit 336A, a second light-emitting unit 336B, and a third light-emitting unit 336C. ​​Each of the first light-emitting unit 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C is disposed within the display area of ​​the display unit 202. Here, one of the first light-emitting units 336A, one of the second light-emitting units 336B, and one of the third light-emitting units 336C are respectively disposed in three display units 202 adjacent to one of the intersection points C212. Several first light-emitting units 336A are arranged in a column along the column direction R, several second light-emitting units 336B are each arranged in a column along the column direction R, and several third light-emitting units 336C are each arranged in a column along the column direction R. Furthermore, the first light-emitting units 336A, the second light-emitting units 336B, and the third light-emitting units 336C are located in different columns. Specifically, in this embodiment, the arrangement of the first light-emitting units 336A, the second light-emitting unit 336B, and the third light-emitting unit 336C can be similar to... Figure 11 The embodiments are the same.

[0086] The first electrode structure 632 includes multiple electrode lines 632L, each of which extends along the row direction C, traversing above multiple display units 202 and contacting multiple light-emitting units 336.

The first electrode lines 634A each extend along the row direction C, while the second electrode lines 634B and third electrode lines 634C each extend along the column direction R. The first electrode lines 634A, 634B, and 634C all extend over the plurality of display units 202. Each first electrode line 634A may be parallel to the electrode lines 632L of the first electrode structure 632, and each first electrode line 634A contacts and is electrically connected to the first light-emitting unit 336A in the same row. The second electrode lines 634B intersect with the electrode lines 632L of the first electrode structure 632, and each second electrode line 634B contacts and is electrically connected to the second light-emitting unit 336B in the same column. The third electrode line 634C intersects with the electrode line 632L of the first electrode structure 632, and each of the third electrode lines 634C contacts and is electrically connected to the third light-emitting unit 336C in the same column.

Thus, the first electrode lines 634A, second electrode lines 634B, and third electrode lines 634C can be used to transmit different signals.

[0089] In this embodiment, the first electrode line 634A is parallel to the electrode line 632L of the first electrode structure 632. The first electrode line 634A and the electrode line 632L can extend to opposite sides in the row direction C to connect to the first signal line 654 and the common signal line 652 respectively.

[0090] Figure 14 This is a partial cross-sectional schematic diagram of the light source structure in the electronic ink layer according to an embodiment of the present invention. Figure 14 The cross-sectional structure can be regarded as Figure 13This is one embodiment of the cross-sectional structure of the light source structure 630 in the electronic ink layer 600, cut along one of the electrode lines 632L, but the present invention is not limited thereto. The light source structure 630 includes a first electrode structure 632, a second electrode structure 634, a plurality of light-emitting units 336, and multiple planarization layers 638.

The layout of the first electrode structure 632, the second electrode structure 634, and the plurality of light-emitting units 336 in the top view can be referred to Figure 13 The relevant description is as follows. In this embodiment, the first electrode structure 632 and the second electrode structure 634 can be implemented using three conductive layer sites MA, MB, and MC. The multilayer planarization layer 638 may include a first planarization layer 638A, a second planarization layer 638B, and a third planarization layer 638C to separate the conductive layer sites MA, MB, and MC.

[0091] In this embodiment, the first electrode line 634A of the second electrode structure 634 is located in the conductive layer MA. The light source structure 630 is applied... Figure 2 In the encapsulation structure 210 shown, the first electrode line 634A can be directly fabricated on the surface of the first encapsulation layer 114 using methods such as printing or coating. In other words, there may be no adhesive layer between the first electrode line 634A and the first encapsulation layer 114. The first light-emitting unit 336A in the light-emitting unit 336 is disposed on and in contact with the first electrode line 634A. The first planarization layer 638A is also disposed on the first electrode line 634A to laterally surround the first electrode line 634A, and the upper surface of the first planarization layer 638A is approximately flush with the upper surface of the first light-emitting unit 336A.

The electrode line 632L can contact the first light-emitting unit 336A. Thus, the electrode line 632L and the first electrode line 634A contact opposite sides of the first light-emitting unit 336A to provide driving current to the first light-emitting unit 336A.

[0093] The second light-emitting unit 336B and the third light-emitting unit 336C in the light-emitting unit 336 are both disposed on and in contact with the electrode line 632L of the first electrode structure 632.

The second planarization layer 638B laterally surrounds the second light-emitting unit 336B and the third light-emitting unit 336C, and the upper surface of the second planarization layer 638B, the upper surface of the second light-emitting unit 336B, and the upper surface of the third light-emitting unit 336C are approximately flush.

[0094] The second electrode line 634B and the third electrode line 634C of the second electrode structure 634 are both located in the conductive layer MC, and the conductive layer MC is disposed on the second planarization layer 638B, the second light-emitting unit 336B, and the third light-emitting unit 336C. ​​The second electrode line 634B and the third electrode line 634C can be conductive lines in the conductive layer MC that are not connected to each other. The second electrode line 634B and the electrode line 632L can contact the opposite surface of the second light-emitting unit 336B to provide driving current to the second light-emitting unit 336B.

[0095] Figure 15 This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. Figure 15 In the middle, the electronic ink layer 700A includes a packaging structure 710A, an electronic ink material 120, a light source structure 130, and a light-shielding pattern 140, wherein the electronic ink material 120, the light source structure 130, and the light-shielding pattern 140 can be referred to Figure 2 The relevant descriptions are as follows. The light source structure 130 may include a first electrode structure 132, a second electrode structure 134, and a light-emitting unit 136. The encapsulation structure 710A includes a separator 712A, a first encapsulation layer 114, and a second encapsulation layer 116. The first encapsulation layer 114 covers the separator 712A. The separator 712A encloses a plurality of encapsulation spaces 712U, and electronic ink material 120 fills the plurality of encapsulation spaces 712U to form a plurality of display units 102. The separator 712A extends between the first encapsulation layer 114 and the second encapsulation layer 116 and has inclined sidewalls S712A. The separator 712A may have a fixed width W712A and a generally parallelogram-shaped cross-sectional structure. Therefore, the inclined sidewalls S712A are inclined relative to the first encapsulation layer 114 and parallel to each other.

[0096] The light-emitting unit 136 is located above the separating member 712A. The light from the light-emitting unit 136 can directly illuminate the display unit 102 or the interface between the separating member 712A and the electronic ink material 120, i.e., the inclined sidewall S712A. The light illuminating the inclined sidewall S712A downwards from the light-emitting unit 136 can be refracted and guided to the display unit 102, which helps to improve light utilization efficiency.

[0097] Figure 16 This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. Figure 16 In this embodiment, the electronic ink layer 700B includes an encapsulation structure 710B, electronic ink material 120, a light source structure 130, and a light-shielding pattern 140. The main difference between the electronic ink layer 700B and the encapsulation structure 710A lies in the design of the encapsulation structure 710B. Therefore, in both embodiments, components labeled with the same element symbol can be referenced to each other. The encapsulation structure 710B includes a separating member 712B, a first encapsulation layer 114, and a second encapsulation layer 116. The width W712B of the separating member 712B gradually decreases from the first encapsulation layer 114 towards the second encapsulation layer 116. The separating member 712B has inclined sidewalls S712B, and all inclined sidewalls S712B are inclined relative to the first encapsulation layer 114. However, the inclined sidewalls S712B of the separating member 712B are inclined in different directions relative to the two sides. Thus, the light emitted by the light-emitting unit 136 shines downwards onto the inclined sidewall S712B and is refracted towards the display unit 102 for use by the display unit 102.

[0098] Figure 17 This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. Figure 17 In this embodiment, the electronic ink layer 700C includes an encapsulation structure 710C, electronic ink material 120, a light source structure 130, and a light-shielding pattern 140. The main difference between the electronic ink layer 700C and the encapsulation structure 710B lies in the design of the encapsulation structure 710C. Therefore, in both embodiments, components labeled with the same element symbol can be referenced to each other. The encapsulation structure 710C includes a separator 712C, a first encapsulation layer 114, and a second encapsulation layer 116. The width W712C of the separator 712C gradually increases from the first encapsulation layer 114 towards the second encapsulation layer 116. The separator 712C has inclined sidewalls S712C, and all inclined sidewalls S712C are inclined relative to the first encapsulation layer 114. However, the inclined sidewalls S712C of the separator 712C are inclined in different directions relative to the two sides. Thus, the light emitted by the light-emitting unit 136 shines downwards onto the inclined sidewall S712C and is refracted towards the display unit 102 for use by the display unit 102.

[0099] Figure 18This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. Figure 18 In the middle, the electronic ink layer 800A includes an encapsulation structure 110, an electronic ink material 120, a light source structure 830A, and a light-shielding pattern 140, wherein the encapsulation structure 110, the electronic ink material 120, and the light-shielding pattern 140 are as follows: Figure 2 The relevant description is as follows. The encapsulation structure 110 includes a separator 112, a first encapsulation layer 114, and a second encapsulation layer 116 to encapsulate the electronic ink material 120 into multiple display units 102. The light source structure 830A includes a first electrode structure 832A, a second electrode structure 834, a light-emitting unit 836, and a planarization layer 838. The planarization layer 838 may include a first planarization layer 838A, a second planarization layer 838B, and a third planarization layer 838C. A light-shielding pattern 140 is disposed on the third planarization layer 838C and located above the light-emitting unit 836.

[0100] The first electrode structure 832A is directly disposed on the upper surface T114 of the first encapsulation layer 114. A first planarization layer 838A laterally surrounds the first electrode structure 832A, and the upper surface of the first planarization layer 838A is substantially flush with the upper surface of the first electrode structure 832A. A light-emitting unit 836 is disposed on the first electrode structure 832A. A second planarization layer 838B laterally surrounds the light-emitting unit 836, and the upper surface of the second planarization layer 838B is substantially flush with the upper surface of the light-emitting unit 836. A third planarization layer 838C laterally surrounds the second electrode structure 834, and the thickness of the third planarization layer 838C may be greater than the thickness of the second electrode structure 834, but is not limited thereto. The light-emitting unit 836 may employ... Figure 2 Central light-emitting unit 136 Figure 7 The light-emitting unit 336 can be implemented in an equivalent or alternative manner. In other words, the individual light-emitting unit 836 can be a white light-emitting unit composed of multiple stacked light-emitting layers, a white light-emitting unit composed of light-emitting layers combined with light-converting materials, or a light-emitting unit that emits a single color.

[0101] In this embodiment, the first electrode structure 832A can be considered as a light guide portion 850 with a light guiding function. Furthermore, the width W850 of the light guide portion 850 tends to increase as it moves further away from the first encapsulation layer 114, causing the sidewall S850 of the light guide portion 850 to be inclined relative to the first encapsulation layer 114. Therefore, the light emitted by the light-emitting unit 836 can be refracted through the sidewall S850 and illuminate the display unit 102.

[0102] Figure 19 This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. Figure 19In the middle, the electronic ink layer 800B includes an encapsulation structure 110, an electronic ink material 120, a light source structure 830B, and a light-shielding pattern 140, wherein the encapsulation structure 110, the electronic ink material 120, and the light-shielding pattern 140 are as follows: Figure 2 The relevant description is as follows. The encapsulation structure 110 includes a separating member 112, a first encapsulation layer 114, and a second encapsulation layer 116 to encapsulate the electronic ink material 120 into multiple display units 102. The light source structure 830B includes a first electrode structure 832B, a second electrode structure 834, a light-emitting unit 836, and a planarization layer 838. The planarization layer 838 may include a first planarization layer 838A, a second planarization layer 838B, and a third planarization layer 838C. A light-shielding pattern 140 is disposed on the third planarization layer 838C and located above the light-emitting unit 836. Specifically, the electronic ink layer 800B differs from the electronic ink layer 800A mainly in the first electrode structure 832B in the light source structure 830B. The remaining components of the electronic ink layer 800B can be referred to... Figure 18 Explanation.

[0103] The first electrode structure 832B includes a light guide portion 850 and a layered portion 852, wherein the layered portion 852 extends continuously on the first encapsulation layer 114, and the light guide portion 850 is disposed between the layered portion 852 and a plurality of light-emitting units 836. The width W850 of the light guide portion 850 gradually decreases from the light-emitting units 836 towards the layered portion 852, such that the sidewall S850 of the light guide portion 850 is inclined relative to the first encapsulation layer 114. Therefore, similar to Figure 18 The light-guiding function of the first electrode structure 832A and the light-guiding part 850 help the light emitted by the light-emitting unit 836 to be refracted and travel toward the display unit 102, thereby improving the light utilization rate of the electronic ink layer 800B.

[0104] Figure 20This is a partial cross-sectional schematic diagram of an electronic ink layer according to an embodiment of the present invention. The electronic ink layer 900 includes an encapsulation structure 910, electronic ink material 120, a light source structure 130, and a plurality of light-shielding patterns 140. The encapsulation structure 910 includes a separating member 912, a first encapsulation layer 114, and a second encapsulation layer 116. The first encapsulation layer 114 covers the separating member 112. The separating member 912 encloses a plurality of encapsulation spaces 912U, and the electronic ink material 120 fills the plurality of encapsulation spaces 912U to form a plurality of display units 902. The second encapsulation layer 116 is located on opposite sides of the separating member 912 to seal the display units 902 therebetween. The light source structure 130 is disposed on the first encapsulation layer 114. The plurality of light-shielding patterns 140 are disposed on the side of the light source structure 130 away from the display units 102. Here, the separating member 912 is, for example, a microcapsule structure, and each display unit 902 may be composed of electronic ink material 120 within the individual encapsulation space 912U surrounded by the microcapsule structure. Furthermore, the design of the first encapsulation layer 114, the second encapsulation layer 116, the electronic ink material 120, the light source structure 130, and the plurality of light-shielding patterns 140 can refer to the foregoing. Figure 2 In the embodiment, the light source structure 130, in addition to Figure 2 In addition to the design described, any one of the light source structures 230, 330, 430, 530, 630, 830A, and 830B described in the foregoing embodiments may be selected for implementation.

[0105] In summary, in the display device of this invention, a light source structure is built into the electronic ink layer, providing an active light-emitting function. Furthermore, the light source structure does not need to be attached to the electronic ink layer, which helps to simplify the overall device size.
