Detailed Implementation Methods

[0058] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0059] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0060] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0061] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0062] This invention provides a display device, such as... Figures 1-3 As shown, Figure 1 This is a schematic diagram of a display device provided in an embodiment of the present invention. Figure 2 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 3 This is another schematic diagram of the display device provided in an embodiment of the present invention. The display device includes a working area 1 and a non-working area 2. The working area 1 can be used to display a working screen, such as displaying static images like text or dynamic images like video. The non-working area 2 is used to display a first color or a first pattern, which can serve as a decorative background for the display device to optimize its shape design. For example, see... Figure 1 Non-working area 2 can display a single color such as black, red, or green, or, see [link to relevant documentation] Figure 2 and Figure 3 Non-working area 2 can also display wood grain and other texture patterns.

[0063] The display device also includes a display module 3, which includes a transparent display unit 4 located in the work area 1 and used to display the work screen.

[0064] In this embodiment of the invention, the display device includes a working area 1 for displaying the working screen and a non-working area 2 for displaying a decorative background. While the working area 1 displays the screen normally, the decorative colors or patterns displayed in the non-working area 2 can enhance the aesthetics and style of the display device. For example, this type of display device can be applied in the automotive field. By displaying a wood grain pattern (first pattern) in the non-working area 2, the interior can be made more luxurious, thus achieving a combination of functionality and aesthetics in the automotive display device. Moreover, in this embodiment of the invention, the display unit used to display the working screen is a transparent display unit 4. Its transparency can weaken the sense of separation between the screen and the surrounding decorative background, helping to optimize the overall effect.

[0065] In one feasible implementation, see Figures 24-26 , Figure 37 , Figure 40 , Figure 42 , Figure 45 and Figure 49 The display module 3 also includes an electronic paper unit 5, which is located on the side of the transparent display unit 4 away from its display surface. The electronic paper unit 5 includes a first sub-part 6 located at least in the working area 1. The transparent display unit 4 can be attached to the electronic paper unit 5 at its edge.

[0066] By further placing an electronic paper unit 5 on the backlight side (i.e., the non-display side) of the transparent display unit 4, the display device can have a more flexible display design. For example, the display device can use the transparent display unit 4 to display some dynamic images with complex patterns and rich colors, and can also use the electronic paper unit 5 to display some text images such as e-book information, thereby presenting more types of images.

[0067] It is understandable that when the electronic paper unit 5 is used to display e-book information, the transparent display unit 4 can be controlled not to display. Since the transparent display unit 4 is transparent, even if the electronic paper unit 5 is located on the backlight side of the transparent display unit 4, the viewer can still clearly see the content displayed by the electronic paper unit 5.

[0068] In addition, the electronic paper module is relatively thin and light, and adding the electronic paper module will not have a significant impact on the overall thickness of the display module 3.

[0069] In one feasible implementation, such as Figures 4-6 As shown, Figure 4 for Figure 1A schematic diagram of the corresponding display device in the first state FS. Figure 5 for Figure 2 A schematic diagram of the corresponding display device in the first state FS. Figure 6 for Figure 3 The corresponding display device is illustrated in one of the first states (FS). The display module 3 includes at least the first state (FS). In the first state (FS), the transparent display unit 4 displays the working screen. Figures 4-6 The illustration uses a hexagonal working screen as an example. The first sub-section 6 displays a dark screen, which can specifically be a black screen.

[0070] In one setup, combined with Figure 15 The transparent display unit 4 includes a display area 14 and a border area 15. The display area 14 is used to display the working screen. When controlling the transparent display unit 4 to display the working screen, the scan line Scan scans the pixels 7 in the display area 14 line by line, and the data line Data transmits display data voltage to the scanned pixels 7 to control the pixels 7 to emit light under the drive of the data voltage.

[0071] When the transparent display unit 4 displays the working screen, the first sub-part 6 in the electronic paper unit 5 is controlled to display a dark screen. This dark screen can increase the contrast of the pattern displayed by the transparent display unit 4, so that the viewer can see the content displayed by the transparent display unit 4 more clearly. In particular, it can significantly improve the black state display effect of the transparent display unit 4.

[0072] In one feasible implementation, such as Figures 7-9 As shown, Figure 7 for Figure 1 A schematic diagram of the corresponding display device in the second state SS. Figure 8 for Figure 2 A schematic diagram of the corresponding display device in the second state SS. Figure 9 for Figure 3 The corresponding display device is shown in a schematic diagram in the second state SS. The display module 3 includes at least the second state SS. In the second state SS, the transparent display unit 4 does not display the working screen, and the screen displayed by the first sub-part 6 is related to the first color or the first pattern.

[0073] In this embodiment of the invention, the image displayed by the first sub-part 6 being related to the first color means that the color of the image displayed by the first sub-part 6 is similar to or the same as the first color. For example, when the first color is black, the color of the image displayed by the first sub-part 6 is also black; or, when the first color is yellow, the color of the image displayed by the first sub-part 6 is also yellow. The image displayed by the first sub-part 6 being related to the first pattern means that the pattern of the image displayed by the first sub-part 6 is similar to or the same as the first pattern type. For example, when the first pattern is a wood grain pattern, the pattern of the image displayed by the first sub-part 6 is also a wood grain pattern.

[0074] In the second state SS, by controlling the image displayed by the first sub-section 6 in the electronic paper unit 5 to be related to the first color or the first pattern, the hiding effect of the transparent display unit 4 when not displaying a working image can be improved. That is, when the transparent display unit 4 is not displaying a working image, the color or pattern of the display device seen by the viewer in the working area 1 and the non-working area 2 is consistent, increasing the degree of integration between the transparent display unit 4 and the surrounding decorative environment, making the color or pattern of the entire display device area blend together, and improving the visual effect. For example, when the display device is applied in the automotive field, the first pattern can be designed as a wood grain pattern. In the second state SS, by controlling the first sub-section 6 in the electronic paper unit 5 to also display the wood grain pattern, the display device can present a complete wood veneer surface. Alternatively, when the display device is applied in the smart home field, the first color can be designed as black. In the second state SS, by controlling the first sub-section 6 in the electronic paper unit 5 to also display black, the display device can present a unified black effect.

[0075] Furthermore, see again Figure 8 In the second state SS, the pattern displayed by the first sub-part 6 has the same background color and pattern color as the pattern of the first pattern, so that the pattern displayed by the first sub-part 6 is consistent with the pattern of the first pattern, thereby effectively improving the hiding effect of the transparent display unit 4 when it is not displaying the working screen, and the overall pattern effect presented by the display device is better.

[0076] It should be noted that when the first sub-part 6 and the first pattern have textures, in one configuration, see [reference needed]. Figure 9 When the patterns in the first pattern are periodically distributed, that is, when the patterns in the first pattern are regularly distributed, the patterns displayed by the first sub-part 6 can also be periodically distributed. In this case, the pattern displayed by the first sub-part 6 can be the same as the first pattern. Alternatively, in another setting, see [link to relevant documentation]. Figure 8When the patterns in the first pattern are irregularly distributed, the extension path of the patterns in the pattern displayed in the first sub-part 6 can be designed according to the extension path of the patterns in the first pattern, so that the patterns displayed in the first sub-part 6 and the patterns extending from the surrounding first pattern are continuous, so that the patterns presented in the working area 1 and the non-working area 2 as a whole are coherent and the visual effect is better.

[0077] Or, see again Figure 7 In the second state SS, the first sub-part 6 displays the first color.

[0078] In this structure, the display device presents only a single color in the non-working area 2. In the second state SS, by making the first sub-part 6 also display a pure color image of that color, visually, the colors of the display device in the working area 1 and the non-working area 2 are the same and continuous, which can also effectively improve the hiding effect of the transparent display unit 4 when it is not displaying a working image.

[0079] In one feasible implementation, such as Figures 10-12 As shown, Figure 10 This is another top view of the display device provided in an embodiment of the present invention. Figure 11 for Figure 10 A schematic diagram of the corresponding display device in the third state TS. Figure 12 for Figure 10 Another schematic diagram of the corresponding display device in the third state TS: the transparent display unit 4 includes pixel 7, and pixel 7 includes a first pixel 8 and a second pixel 9. The display module 3 includes at least the third state TS. In the third state TS, the first pixel 8 does not emit light, the second pixel 9 emits light, and the image displayed by the first sub-part 6 is related to a first color or a first pattern.

[0080] The electronic paper unit 5 typically uses the reflection of ambient light to achieve display. In the third state TS, when the first sub-section 6 of the electronic paper unit 5 displays an image related to a first color or a first pattern, see [reference needed]. Figure 12 By controlling the second pixel 9 in the transparent display unit 4 to emit light, part of the light emitted by the second pixel 9 will be transmitted toward the electronic paper unit 5, thereby increasing the amount of light entering the first sub-part 6 in the electronic paper unit 5 and improving the display effect of the first sub-part 6.

[0081] In the embodiments of the present invention, see again Figure 12 The electronic paper unit 5 may specifically include a substrate 10, which includes a receiving cavity 11 and electrophoretic particles 12. In addition, the electronic paper unit 5 may also include a color filter layer 13 located on one side of the substrate 10, so that the electronic paper unit 5 can realize color display and better display the image related to the first color or the first pattern.

[0082] Furthermore, it should be noted that the third state TS can also be the same as the second state SS described above. When the two are in the same state, the transparent display unit 4 does not display a working screen, but some pixels 7 emit light to provide incident light to the electronic paper unit 5. This makes the pattern or texture presented by the electronic paper unit 5 visually closer to the pattern or texture presented by the non-working area 2, thereby better hiding the display module.

[0083] In one feasible implementation, see again Figure 10 The second pixel 9 surrounds the first pixel 8.

[0084] It should be noted that, in the embodiments of the present invention, the second pixel 9 surrounding the first pixel 8 refers to the second pixel 9 surrounding the first pixel 8 in terms of arrangement or arrangement path, and does not refer to surrounding in terms of shape.

[0085] It is understandable that when viewing the transparent display unit 4, viewers are more likely to focus on the image presented in the large central area. Therefore, in this embodiment of the invention, by designing the second pixel 9, which emits light in the third state TS, to be located around the non-emitting first pixel 8, the amount of light entering the electronic paper unit 5 is increased by utilizing the second pixel 9, while also avoiding any significant impact of the second pixel 9 emitting light on the state of the central area of ​​the transparent display unit 4.

[0086] Furthermore, it should be noted that the above scheme only limits the second pixel 9 to surround the first pixel 8, that is, the second pixel 9 is located between the first pixel 8 and the edge of the transparent display unit 4, but does not specifically limit whether the second pixel 9 and the first pixel 8 are located in the display area 14 or the border area 15 of the transparent display unit 4. In the embodiments of the present invention, the second pixel 9 can be located in the border area 15, or in the display area 14, or simultaneously in both the border area 15 and the display area 14. The embodiments of the present invention will be described in detail in the following embodiments.

[0087] In one feasible implementation, such as Figure 13 As shown, Figure 13 This is a top view of the transparent display unit 4 provided in an embodiment of the present invention. The transparent display unit 4 includes a display area 14 and a border area 15. The display area 14 is used to display the working screen. The first pixel 8 is located in the display area 14, and at least part of the second pixel 9 is located in the border area 15.

[0088] In the above structure, at least a portion of the second pixel 9 is located in the border area 15. Since this portion of the second pixel 9 does not occupy the space of the display area 14, when this portion of the second pixel 9 emits light in the third state TS, it will not affect the state of the display area 14.

[0089] Furthermore, such as Figure 14 As shown, Figure 14 This is another top view of the transparent display unit 4 provided in an embodiment of the present invention. Part of the second pixel 9 is located in the display area 14 and surrounds the first pixel 8. In the third state TS, the luminous intensity of the second pixel 9 in the display area 14 is less than the DD232373I-IMP luminous intensity of the second pixel 9 in the border area 15.

[0090] On the one hand, by surrounding the second pixel 9, the transparent display unit 4 can display the image that the user needs to see without affecting the normal display of the image. On the other hand, the brightness of the second pixel 9 in the display area 14 is less than that of the second pixel 9 in the border area 15. Therefore, this part of the second pixel 9 in the display area 14 can be used to form a brightness transition between the second pixel 9 in the border area 15 and the first pixel 8 in the display area 14, which reduces the risk that the light emitted by the second pixel 9 is visible to the human eye, and also reduces the risk that the border area is visible to the human eye.

[0091] In one feasible implementation, see again Figure 13 and Figure 14 The display module 3 also includes a masking layer 16, which is located on one side of the display surface of the transparent display unit 4, and at least a portion of the second pixel 9 overlaps with the masking layer 16. In one configuration, the masking layer 16 may be an ink layer located in the border area 15, used to mask the peripheral circuitry of the border area 15.

[0092] To optimize the light-blocking properties of the masking layer 16, it is generally made of a darker material. This results in a noticeable black area forming within the transparent display unit 4. For example, when the masking layer 16 is an ink layer, it forms a distinct black border around the transparent display unit 4. In the third state TS, when the first sub-section 6 in the electronic paper unit 5 displays an image related to the first color or pattern, this black border affects the overall presentation of the working area 1 and the non-working area 2. To address this, this embodiment of the invention overlaps the second pixel 9 with the masking layer 16. When light emitted from the second pixel 9 illuminates the masking layer 16, it softens the black border of the masking area, making the visually formed seam lighter, thereby improving the overall presentation of the working area 1 and the non-working area 2 in the third state TS.

[0093] In one feasible implementation, such as Figure 15 As shown, Figure 15This is another top view of the transparent display unit 4 provided in an embodiment of the present invention. The transparent display unit 4 further includes data lines Data, which include a first data line Data-1 and a second data line Data-2. The second pixel 9 includes a first type of second pixel 17 and a second type of second pixel 18. The first data line Data-1 is electrically connected to the first type of second pixel DD232373I-IMP 17, and at least one second data line Data-2 is electrically connected to both the second type of second pixel 18 and the first pixel 8.

[0094] In the third state TS, the first data line Data-1 provides the bright state data voltage V1, and the second data line Data-2 provides the bright state data voltage V1 when scanning the second pixel 18 of the second class and the dark state data voltage V2 when scanning the first pixel 8.

[0095] In the above structure, the data line Data includes two types of data lines Data: a first data line Data-1 and a second data line Data-2. The first data line Data-1 is electrically connected only to the second pixel 9. Therefore, in the third state TS, the first data line Data-1 can continuously provide a bright state data voltage V1 to drive the second pixel 9 to emit light. The second data line Data-2 is electrically connected to both the first pixel 8 and the second pixel 9. Since the first pixel 8 and the second pixel 9 have different light emission states in the third state TS, the voltage provided by the second data line Data-2 needs to take into account the scanning situation of the first pixel 8 and the second pixel 9. Specifically, the second data line Data-2 needs to provide a bright state data voltage V1 when scanning the second type of second pixel 18 to drive the second pixel 9 connected to it to emit light, and provide a dark state data voltage V2 when scanning the first pixel 8 to drive the first pixel 8 connected to it not to emit light.

[0096] Furthermore, see again Figure 15 The transparent display unit 4 includes a display area 14 and a border area 15. The display area 14 is used to display the working screen. The border area 15 includes a first border area 19 and a second border area 20. The arrangement direction of the first border area 19 and the display area 14 intersects the extension direction of the data line Data, and the arrangement direction of the second border area 20 and the display area 14 is parallel to the extension direction of the data line Data. That is, the first border area 19 can be understood as the left and right borders, and the second border area 20 can be understood as the top and bottom borders.

[0097] In the area, the first pixel 8 is located in the display area 14, the first type of second pixel 17 is located in the first border area 19, and the second type of second pixel 18 is located in the second border area 20.

[0098] Specifically, the transparent display unit 4 also includes a scan line Scan, the extension direction of which intersects the extension direction of the data line Data. The scan line Scan includes a first scan line Scan-1 and a second scan line Scan-2. The first scan line Scan-1 is electrically connected to the second pixel 9. For example, the first scan line Scan-1DD232373I-IMP is electrically connected to the second type second pixel 18, or the first scan line Scan-1 is electrically connected to the first type second pixel 17 and the second type second pixel 18. The second scan line Scan-2 is electrically connected to the first type second pixel 17 and the first pixel 8.

[0099] Based on this structure, the aforementioned "the second data line Data-2 provides a bright state data voltage V1 when scanning the second type of second pixel 18 and a dark state data voltage V2 when scanning the first pixel 8" specifically means that "when the first scan line Scan-1 provides a scan signal to the second type of second pixel 18, the second data line Data-2 provides a bright state data voltage V1, and when the first scan line Scan-1 or the second scan line Scan-2 provides a scan signal to the first pixel 8, the second data line Data-2 provides a dark state data voltage V2."

[0100] Unlike traditional display units, in this embodiment of the invention, the transparent display unit 4 also has pixels 7 in the border area 15, and the pixels 7 in the border area 15 are also electrically connected to the scan line Scan. Therefore, when the scan line Scan scans from top to bottom or from bottom to top in one round, it should be regarded as refreshing all the pixels 7 in the border area 15 and the display area 14 in one round.

[0101] Taking the electrical connection of the first scan line Scan-1 with the first type of second pixel 17 and the second type of second pixel 18 as an example, such as Figure 16 As shown, Figure 16 This is a timing diagram of the display device provided in the third state TS according to an embodiment of the present invention. For clarity, Figure 15 and 16In this diagram, the two first scan lines Scan-1 are denoted as Scan-1_1 and Scan-1_2, respectively, and the first to nth second scan lines Scan-2 are denoted as Scan-2_1 to Scan-2_n, respectively. In the third state TS, firstly, the first scan line Scan-1_1 provides an enable level to the first type of second pixel 17 and the second type of second pixel 18 connected to it. The bright state data voltage V1 provided by the first data line Data-1 is written to the first type of second pixel 17, driving it to emit light. The bright state data voltage V1 provided by the second data line Data-2 is written to the second type of second pixel 18, driving it to emit light. Then, the second scan lines Scan-2_1 to Scan-2_n sequentially provide enable levels. When the second scan line Scan-2_i provides an enable level to the first type of second pixel 17 and the first pixel 8 connected to it... The first data line Data-1 provides a bright-state data voltage V1, which is written to the first type of second pixel 17, causing it to emit light. The second data line Data-2 provides a dark-state data voltage V2, which is written to the first pixel 8, causing it to not emit light. Finally, the first scan line Scan-1_2 provides an enable level to the first type of second pixel 17 and the second type of second pixel 18 connected to it. The bright-state data voltage V1 provided by the first data line Data-1 is written to the first type of second pixel 17, causing it to emit light, and the bright-state data voltage V1 provided by the second data line Data-2 is written to the second type of second pixel 18, causing it to emit light. This achieves the effect that in the third state TS, the second pixel 9 emits light, while the first pixel 8 does not emit light.

[0102] The above structure uses a shared set of Scan lines and a set of Data lines to drive the second pixel 9 and the first pixel 8. The original driving method can be used to drive the second pixel 9, and there is no need to configure a separate driving method for the second pixel 9.

[0103] Furthermore, combined Figure 15 and Figure 17 ,like Figure 17 As shown, Figure 17 This is another timing diagram of the display device provided in the third state TS according to an embodiment of the present invention. The display module 3 includes at least a first state FS. In the first state FS, the transparent display unit 4 displays the working screen, and the portion of the electronic paper unit 5 located in the working area 1 displays a dark screen. In the first state FS, the first data line Data-1 provides a black state data voltage V2, and the second data line Data-2 provides a black state data voltage V2 when scanning the second type of second pixel 18, and provides a display data voltage V when scanning the first pixel 8. The display data voltage V is the data voltage used to display the working screen.

[0104] Taking the first scan line Scan-1 electrically connected to the first type of second pixel 17 and the second type of second pixel 18 as an example, in the third state TS, firstly, the first scan line Scan-1_1 provides an enable level to the first type of second pixel 17 and the second type of second pixel 18 connected to it. The black state data voltage V2 provided by the first data line Data-1 is written to the first type of second pixel 17, driving the first type of second pixel 17 to not emit light. The black state data voltage V2 provided by the second data line Data-2 is written to the second type of second pixel 18, driving the second type of second pixel 18 to not emit light. Then, the second scan lines Scan-2_1 to Scan-2_n sequentially provide enable levels, and the second scan line Scan-2_i provides an enable level to the first type of second pixel 17 and the second type of second pixel 18 connected to it. When the second pixel 17 and the first pixel 8 are given an enable level, the black state data voltage V2 provided by the first data line Data-1 is written to the first second pixel 17, driving it to not emit light. The display data voltage V provided by the second data line Data-2 is written to the first pixel 8, driving it to emit light. Finally, the first scan line Scan-1_2 provides an enable level to the first second pixel 17 and the second second pixel 18 connected to it. The black state data voltage V2 provided by the first data line Data-1 is written to the first second pixel 17, driving it to not emit light. The black state data voltage V2 provided by the second data line Data-2 is written to the second second pixel 18, driving it to not emit light. This is how the display area 14 displays the working screen in the first state FS.

[0105] In one feasible implementation, such as Figure 18 As shown, Figure 18 In another top view of the transparent display unit 4 provided in the embodiment of the present invention, the first pixel 8 and the second pixel 9 can both be located in the display area 14, with the second pixel 9 surrounding the first pixel 8. That is, the second pixel 9 is located between the first pixel 8 and the edge of the display area 14. In this case, there is no need to add a pixel 7 in the border area 15 of the transparent display unit 4, and the structural design is simpler.

[0106] In one feasible implementation, such as Figure 19 As shown, Figure 19 This is a schematic diagram of a display device provided in an embodiment of the present invention in a fourth state KS. The display device includes at least a fourth state KS. In the fourth state KS, the transparent display unit 4 does not display a working screen, and the screen displayed by the first sub-part 6 in the electronic paper unit 5 is unrelated to the first color or the first pattern. That is, the first sub-part 6 can display any other screen, thereby increasing the flexibility of the overall appearance of the display device. For example, see [link to example]. Figure 19 Non-working area 2 is black. In the fourth state KS, the first sub-section 6 can display a wood grain pattern.

[0107] In one feasible implementation, such as Figure 20 and Figure 21 As shown, Figure 20 This is a cross-sectional view of the transparent display unit 4 provided in an embodiment of the present invention. Figure 21 This is another top view of the display device provided in an embodiment of the present invention. The transparent display unit 4 includes a pixel 7 and a light-blocking layer 21, which are located on one side of a substrate 22. The light-blocking layer 21 includes an opening 23 that exposes the light-emitting area of ​​the pixel 7. The color of the light-blocking layer 21 is the same as the background color of the first pattern. For example, when the first pattern is a wood grain pattern, the light-blocking layer 21 can be formed using a light-blocking material with the same background color as the wood grain pattern.

[0108] Traditionally, the light-blocking layer 21 is a black matrix. In this embodiment of the invention, the color of the light-blocking layer 21 can be further adjusted. When the display device presents the first pattern in the non-working area 2, by making the color of the light-blocking layer 21 the same as the background color of the first pattern, the color of the light-blocking layer 21 can be made close to the color of the first pattern, thereby further increasing the concealment of the transparent display unit 4 when the transparent display unit 4 does not display the working screen (e.g., in the second state SS or the third state TS).

[0109] In one feasible implementation, such as Figure 22 and Figure 23 As shown, Figure 22 This is another cross-sectional view of the transparent display unit 4 provided in an embodiment of the present invention. Figure 23 This is another top view of the display device provided in an embodiment of the present invention. The transparent display unit 4 includes pixels 7 and a light-blocking layer 21. The light-blocking layer 21 includes an opening that exposes the light-emitting area of ​​the pixels 7. The color of the light-blocking layer 21 is a first color. For example, when the first color is black, the light-blocking layer 21 can be formed using a black light-blocking material, thereby further increasing the concealment of the transparent display unit 4 when it is not displaying a working screen (e.g., in the second state SS or the third state TS).

[0110] In one feasible implementation, such as Figure 24 and Figure 25 As shown, Figure 24 This is a schematic diagram of a display device provided in an embodiment of the present invention. Figure 25 This is another schematic diagram of the display device provided in an embodiment of the present invention. The display device further includes a carrier module 24. At least a portion of the carrier module 24 exposed by the display module 3 is located in the non-working area 2 and displays a first color or a first pattern. That is, at least a portion of the carrier module 24 exposed by the display module 3 displays a first color or a first pattern.

[0111] It should be noted that the accompanying drawings of this embodiment are only illustrative of the example where at least a portion of the carrier module 24 exposed by the display module 3 presents a wood grain pattern, but in combination with... Figures 1-3 It is understood that at least part of the carrier module 24 exposed by the display module 3 can also display other patterns and any single color, which will not be illustrated in detail in this embodiment of the invention.

[0112] In this structure, the first color or first pattern used for decoration in the display device is presented by the part of the carrier module 24 exposed by the display module 3. The carrier module 24 can be any object used to support the module 24, such as a platform. The display device with this structure can be applied to more application scenarios.

[0113] Furthermore, such as Figures 26-28 As shown, Figure 26 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 27 for Figure 26 A sectional view along A1-A2, Figure 28 for Figure 26 In another sectional view along A1-A2, the display module 3 is embedded in the support module 24, that is, the support module 24 is provided with a groove, and the display module 3 is placed in the groove.

[0114] This design reduces the step difference between the surface of the display module 3 and the surface of the support module 24. When the viewer touches the display device, the entire surface of the display device tends to be continuous, providing a better experience both visually and tactilely.

[0115] It should be noted that when the carrier module 24 has a wood grain pattern, because a groove needs to be carved out in the carrier module 24, the color or pattern of the surface of the carrier module 24 that is obscured by the display module 3 and the color or pattern of the surface exposed by the display module 3 may be inconsistent when viewed from a top-down angle. For example, as Figure 29 As shown, Figure 29 This is a top view of the carrier module 24 provided in an embodiment of the present invention. The texture of the surface of the carrier module 24 that is covered by the display device and the texture of the surface exposed by the display module 3 have different orientations. However, as can be seen from the foregoing description, the display module 3 may include the electronic paper unit 5. Therefore, in the second state SS or the third state TS, when the transparent display unit 4 does not display the working screen, combined with... Figure 8 The first sub-part 6 in the electronic paper unit 5 can be used to present a texture that is continuous with the texture of the surface exposed by the display module 3 in the carrier module 24, so as to optimize the overall pattern presentation effect of the display device.

[0116] In other words, the color or pattern of the part of the carrier module 24 that is covered by the display module 3 may not be the same as the color or pattern of the part that is exposed by the display module 3. That is, in the second state SS or the third state TS, the color or pattern presented by the first sub-part 6 may not be the same as the color or pattern of the surface of the carrier module 24 that is covered by the display module 3.

[0117] Furthermore, it should be noted that in embodiments where the display device includes the carrier module 24, whether the display module 3 is placed on one side of the carrier module 24 or embedded in the carrier module 24, the display module 3 may include a transparent display unit 4, or it may simultaneously include a transparent display unit 4 and an electronic paper unit 5. When the display module 3 simultaneously includes a transparent display unit 4 and an electronic paper unit 5, the working principles of the transparent display unit 4 and the electronic paper unit 5 have been described in detail in the above embodiments and will not be repeated here.

[0118] In one feasible implementation, see again Figures 24-28 The carrier module 24 includes a first surface 25, and the display module 3 has a light-emitting surface 26. The first surface 25 and the light-emitting surface 26 have the same orientation. The first surface 25 is exposed by the light-emitting surface 26. The first surface 25 has a first color or a first pattern. At this time, the first surface 25 with the first color or the first pattern in the carrier module 24 and the light-emitting surface 26 of the display module 3 are both facing the viewer's viewing angle.

[0119] Furthermore, such as Figure 30 As shown, Figure 30 This is a schematic diagram of the step difference between the first surface 25 and the light-emitting surface 26 provided in an embodiment of the present invention. The step difference d between the first surface 25 and the light-emitting surface 26 is less than 100μm, which avoids the display module 3 protruding too much from the support module 24 or recessing too much from the support module 24, thereby optimizing the visual and tactile effects.

[0120] It should be noted that the step difference d between the first surface 25 and the light-emitting surface 26 being less than 100 μm can include cases where the first surface 25 is higher than the light-emitting surface 26, or cases where the light-emitting surface 26 is higher than the first surface 25. Figure 30 The illustration is based on the example where the first surface 25 is higher than the light-emitting surface 26.

[0121] In one feasible implementation, such as Figure 31 As shown, Figure 31 This is another schematic diagram of the step difference between the first surface 25 and the light-emitting surface 26 provided in an embodiment of the present invention. The first surface 25 and the light-emitting surface 26 are continuous to achieve better visual and tactile effects.

[0122] In one feasible implementation, such as Figures 32-35 As shown, Figure 32 This is another cross-sectional view of the display device provided in an embodiment of the present invention. Figure 33 for Figure 32 A sectional view along B1-B2, Figure 34 This is another cross-sectional view of the display device provided in an embodiment of the present invention. Figure 35 for Figure 34 In a cross-sectional view along C1-C2, the display module 3 further includes an ink layer 27, which is located on one side of the display surface of the transparent display unit 4. (See also...) Figure 32 and Figure 33 The color of ink layer 27 is the first color, or, see [link to other ink layers]. Figure 34 and Figure 35 The pattern of the ink layer 27 is related to the first pattern, so that when the transparent display unit 4 does not display the working screen, the color or pattern of the ink layer 27 is integrated with the first color or first pattern of the surrounding non-working area 2, thus weakening the boundary formed by the ink layer 27.

[0123] The transparent display unit 4 includes a display area 14 and a border area 15. The ink layer 27 may be located in the border area 15 to cover the peripheral circuits of the transparent display unit 4.

[0124] It should be noted that if the color of ink layer 27 is to be the first color, the light-blocking material of the first color can be directly selected to form ink layer 27. If the pattern of ink layer 27 is to be related to the first pattern, screen printing technology can be used to process ink layer 27 to have a related pattern.

[0125] In one feasible implementation, see again Figure 33 and Figure 35 The display module 3 also includes a cover plate 28, which is located on one side of the display module 3 and in the working area 1, so as to protect the screen of the transparent display unit 4.

[0126] In one feasible implementation, such as Figures 36-40 As shown, Figure 36 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 37 for Figure 36 A sectional view along the D1-D2 direction. Figure 38 for Figure 36 A sectional view along the E1-E2 direction. Figure 39 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 40 for Figure 39A cross-sectional view along the F1-F2 direction shows that the display module 3 further includes a cover plate 28, which is located on one side of the display module 3 and at least in the working area 1. The display device also includes a first module 29, which is located on one side of the cover plate 28 and at least in the non-working area 2. See [reference needed]. Figure 39 and Figure 40 The first module 29 displays the first color, or see [link to module 29]. Figures 36-38 The first module 29 presents the first pattern.

[0127] This configuration involves placing a first module 29 on one side of the cover plate 28, and using the first module 29 to form the decorative background of the display device. In this structure, the decorative color or pattern to be displayed by the display device is closer to the light-emitting side of the display device, resulting in a clearer display effect.

[0128] In one feasible implementation, see again Figures 36-40 The cover plate 28 is also located in the non-working area 2. The first module 29 includes an ink layer 27, which is located on the side of the cover plate 28 facing the transparent display unit 4. The ink layer 27 presents a first color or a first pattern.

[0129] This structure features a large cover plate 28, with an ink layer 27 bearing a first color or pattern on one side. The ink layer 27 is used to present decorative colors or patterns. Firstly, the display device is entirely covered by the cover plate 28, so when a viewer touches the display device, they are touching the entire outer surface of the cover plate 28. Because the surface roughness of the cover plate 28 is uniform, the viewer's tactile experience is superior. Secondly, when the ink layer 27 needs to present a first pattern, this structure allows for direct screen printing to achieve this specific pattern. Screen printing technology is relatively mature and offers greater feasibility.

[0130] In one feasible implementation, such as Figures 41-43 As shown, Figure 41 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 42 for Figure 41 A cross-sectional view along the G1-G2 direction. Figure 43 for Figure 41 A cross-sectional view along the H1-H2 direction shows that the first module 29 includes a housing 30 located on the side of the cover plate 28 away from the transparent display unit 4. The housing 30 is a first color or a first pattern. For example, when the housing 30 is black, it may also be formed of black ink material, or it may be formed of plastic.

[0131] This structure has a housing 30 as a first module 29 on the outside of the cover plate 28. By giving the housing 30 a first color or a first pattern, the display device can present the desired decorative color or decorative pattern in the non-working area 2.

[0132] Furthermore, see again Figure 41 The housing 30 includes a cutout 31, which is located in the non-working area 2, and the cover plate 28 does not overlap with the cutout 31.

[0133] This structure features a special design for the shape of the display device, making it particularly suitable for use in the automotive field. The cutout 31 in the housing 30 can be used as an air vent for the vehicle's air conditioning system.

[0134] In one feasible implementation, see again Figure 36 , Figure 39 and Figure 41 The transparent display unit 4 includes a display area 14 and a border area 15. The display area 14 is used to display the working screen. The first module 29 also overlaps with the border area 15. At this time, the part of the first module 29 that overlaps with the border area 15 can be used to cover the peripheral circuit of the transparent display unit 4.

[0135] For example, see Figure 41 The housing 30 overlaps with the frame area 15, and the housing 30 can be used to cover the peripheral circuit of the transparent display unit 4. At this time, there is no need to set an ink layer between the cover plate 28 and the transparent display unit 4.

[0136] Furthermore, it should be noted that in embodiments where the display device includes the first module 29, the display module 3 may include a transparent display unit 4, or it may simultaneously include a transparent display unit 4 and an electronic paper unit 5. When the display module 3 simultaneously includes a transparent display unit 4 and an electronic paper unit 5, the working principles of the transparent display unit 4 and the electronic paper unit 5 have been described in detail in the above embodiments and will not be repeated here.

[0137] In one feasible implementation, such as Figure 44 and Figure 45 As shown, Figure 44 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 45 for Figure 44 A cross-sectional view along I1-I2 shows that the electronic paper unit 5 also includes a second sub-section 32 located in the non-working area 2, combined with... Figures 4-9 The second sub-section 32 displays a first color or a first pattern. Specifically, in the first state FS, the second state SS, and the third state TS, the second sub-section 32 of the electronic paper unit 5 displays the first color or the first pattern.

[0138] In this configuration, by using a large-sized electronic paper unit 5 and placing it in both the working area 1 and the non-working area 2, the second sub-section 32 in the electronic paper unit 5 can be used directly to display an image with a first color or an image with a first pattern, thereby presenting the decorative background of the display device. This eliminates the need for additional or even other structures to present the decorative background, making the overall structure of the display device simpler and thinner.

[0139] Moreover, when the decorative pattern is the first pattern, based on this design, in the second state SS and the third state TS, the electronic paper unit 5 can display a complete pattern in the working area 1 and the non-working area 2. The part of the complete pattern located in the non-working area 2 serves as the decorative background, and the part of the complete pattern located in the working area 1 serves as the pattern related to the decorative background that needs to be presented in the working area 1. In this way, the completeness and coherence of the overall pattern are higher, and the effect is better.

[0140] In one feasible implementation, combined with Figure 44 and Figure 45 ,like Figure 46 As shown, Figure 46 This is another top view of the display device provided in an embodiment of the present invention. The display module 3 also includes a cover plate 28, which is located on the side of the transparent display unit 4 facing away from the electronic paper unit 5. The cover plate 28 is located in the non-working area 2 and the working area 1 to protect the display structure.

[0141] The transparent display unit 4 includes a display area 14 and a border area 15. The display area 14 is used to display the working screen, and the border area 15 is located between the non-working area 2 and the display area 14. The display module 3 also includes an ink layer 27, which is located on the side of the transparent display unit 4 facing the display surface, and the ink layer 27 is located at least in the border area 15.

[0142] Based on this structure, in the non-working area 2, there is an air gap between the cover plate 28 and the second sub-section 32 in the electronic paper unit 5. Because the refractive index of the cover plate 28 and the air differs significantly, when the electronic paper unit 5 displays an image, for example... Figure 46 Taking the display of a wood grain pattern in the second state SS of the electronic paper unit 5 as an example, ambient light is significantly refracted at the interface between the cover plate 28 and the air, resulting in a noticeable visual height difference at the junction of the non-working area 2 and the working area 1. For example, the texture at this location may become discontinuous. To address this, this embodiment of the invention provides an ink layer 27 at the border area 15. The ink layer 27 can be used to form a black seam at the junction of the non-working area 2 and the working area 1, creating a special seam effect that directly conceals the visual height difference caused by refraction.

[0143] In one feasible implementation, see again Figure 45 The ink layer 27 is also located in the non-working area 2, so as to use the ink layer 27 to simultaneously cover the visual height difference under the normal viewing angle and the oblique viewing angle.

[0144] Furthermore, such as Figure 47 As shown, Figure 47 for Figure 45 A partially enlarged schematic diagram shows that the portion of the ink layer 27 located in the non-working area 2 has a first width d1, and the portion of the ink layer 27 located in the border area 15 has a second width d2. In order to avoid the edge width being too large and to make it more aesthetically pleasing, the first width d1 can be smaller than the second width d2.

[0145] In one feasible implementation, such as Figure 48 and Figure 49 As shown, Figure 48 This is another structural schematic diagram of the display device provided in an embodiment of the present invention. Figure 49 for Figure 48 In a cross-sectional view along J1-J2, the display module 3 also includes a cover plate 28 located in the non-working area 2 and the working area 1. A transparent display unit 4 is embedded in the cover plate 28 on the side of the cover plate 28 closest to the electronic paper unit 5.

[0146] In this structure, by embedding the transparent display unit 4 into the cover plate 28, the gap between the cover plate 28 and the electronic paper unit 5 can be reduced in the non-working area 2, or even the cover plate 28 can be in direct contact with the electronic paper unit 5. Thus, the visual height difference caused by the difference in refractive index between the cover plate 28 and the air mentioned above can be effectively overcome.

[0147] Furthermore, the transparent display unit 4 is embedded in the cover plate 28, which provides more comprehensive protection for the transparent display unit 4 and the electronic paper unit 5, resulting in better protection performance.

[0148] Furthermore, in this embodiment of the invention, the transparent display unit 4 and the electronic paper unit 5 can also share a power supply, DD232373I-IMP, or a printed circuit board to achieve higher integration.

[0149] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0150] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
