Description

Technical Field

[0001] This invention relates to the field of display systems. Specifically, the invention describes apparatus and manufacturing methods for display systems suitable for a range of applications, particularly for automotive display systems. Background Art

[0002] A display system may include connecting at least two different display devices. These different display devices used in such a display system may include a combination of high-resolution display devices (such as liquid crystal displays (LCDs) or organic light-emitting diode (OLED) displays) and low-resolution display devices (such as light-emitting diode (LED) display devices for backlighting).

[0003] Different types of display devices are typically used to present visual information to users, thereby representing images, videos, and other visual content. In automotive display systems, by connecting multiple discrete display devices within a single display system, more information can be provided to the viewer.

[0004] Different types of display devices used in display systems can employ a range of different technologies. Some examples include non-emissive liquid crystal displays (LCDs) that utilize liquid crystals with backlighting, organic light-emitting diode (OLED) displays that use organic compounds that emit light when an electric current is applied, and MicroLED displays that utilize tiny light-emitting diodes as individual display pixels. Furthermore, as discussed above, display devices can also include light-emitting diode (LED) display devices for backlighting, such as LED light bricks.

[0005] High-resolution display devices (e.g., LED or OLED) typically comprise a panel with an effective display area and ineffective display areas. The effective display area is the region of the display device where visual content is presented. The ineffective display area typically includes an opaque boundary that generally surrounds one or more edges of the effective area. This opaque boundary can serve either as a structural component providing support for the display device or as a housing for the various components or structures required to house the display device. Specifically, the opaque boundary region typically contains the various electrical components or circuitry required to control individual pixels within the effective display area.

[0006] Because the electrical components of display devices are typically light-sensitive, they usually require some form of protection. Typically, electrical connections and circuits are protected by an opaque black mask to ensure adequate protection of the electronic components. Therefore, the opaque black mask is often also present within the field of view at the edge of the display device.

[0007] Due to the standard construction of traditional display devices, typical display systems in this field often include opaque boundaries between each individual display device. Therefore, such display systems are not fully immersive for the user because there is no seamless transition between discrete elements within a single system and adjacent display devices.

[0008] Examples of systems and methods known in the art include U.S. Patent No. 7,540,628 B2, International Patent Publication No. WO2008 / 120879 A1, U.S. Patent No. 9,377,652 B, Korean Patent No. KR 102135867 B1, and Chinese Patent Application No. CN 113281928 A.

[0009] Typically, a device and method are needed to solve the above problems.

[0010] One aspect of the present invention is to provide a display system that eliminates or mitigates one or more drawbacks or disadvantages of the prior art.

[0011] Further objectives and objects of the present invention will become apparent from the following description. Summary of the Invention

[0012] According to a first aspect of the present invention, a display system is provided, the display system comprising:

[0013] First volume and second volume;

[0014] An output surface, the output surface including a first display block located within the first volume and a second display block located within the second volume;

[0015] A first display device, the first display device being located within the first volume;

[0016] A second display device, located within the second volume, comprising an effective display area surrounded by a non-effective display area; and

[0017] An optical guide that extends at least partially through the first volume and the second volume;

[0018] The light guide couples light from the first display device to illuminate a portion of the second volume located between the ineffective display area and the output surface.

[0019] The display system of the present invention advantageously allows light to be guided from the first volume to the second volume. The second display device includes a non-active display area that independently provides an opaque boundary on the output surface between the first and second display blocks. However, the light guide is configured such that a portion of the second volume located between the non-active display area and the second display block on the output surface can be illuminated by light generated in the first volume. Therefore, the light guide provides a seamless transition between the first and second volumes. The light guide makes the portion of the second volume including the non-active display area of ​​the second display device non-opaque. Therefore, the area of ​​the second display block within the portion of the second volume including the non-active display area will not appear completely opaque to the viewer of the display system. Thus, the above-described display system can provide users with a more immersive display and a more immersive experience.

[0020] Most preferably, the light guide is located between the output surface and the first display device and the second display device.

[0021] Preferably, the outer cladding is disposed on the portion of the light guide located within the first volume. The outer cladding prevents light from illuminating the output surface within the first display block from the light guide.

[0022] The ineffective display area can surround one or more sides of the effective display area.

[0023] Preferably, the display system further includes a diffuser. Preferably, the diffuser extends at least partially through the first volume and the second volume. The diffuser may be located between the output surface and the light guide. The diffuser provides improved uniformity and viewing characteristics for the light emitted by the display system.

[0024] Alternatively, the light guide is integrated into the diffuser. By combining the light guiding and light diffusing functions into a single component, optical performance can be improved.

[0025] Preferably, the output surface includes a cover glass that extends through the first display block and the second display block. The cover glass provides a protective outer layer covering the front or viewing surface of the display system.

[0026] Preferably, the cover glass is a two-dimensional cover glass. Alternatively, the cover glass is a three-dimensional cover glass. Optionally, the three-dimensional cover glass extends around the diffuser and the light guide.

[0027] Extending the cover glass around the diffuser and the light guide prevents the light guide from illuminating a portion of the second volume located between the effective display area of ​​the second display device and the output surface.

[0028] Optionally, the display system further includes a reflector. Preferably, the reflector is located between the ineffective display area of ​​the second display device and the light guide.

[0029] The reflector can improve the illumination on the ineffective display area of ​​the second display device by reflecting any incident light back to the light guide.

[0030] Preferably, the light guide is a two-dimensional light guide. Alternatively, the light guide is a 2.5-dimensional or 3-dimensional light guide. By changing the shape of the light guide, improved illumination can be achieved on the ineffective display area of ​​the second display device.

[0031] Preferably, the ineffective display area of ​​the second display device includes a black mask. Preferably, the black mask is optically opaque. The opaque black mask provides protection for any photosensitive electronic devices present in the ineffective display area of ​​the second display device.

[0032] Preferably, the first display device includes a light-emitting diode display device.

[0033] Preferably, the light-emitting diode display device is a light-emitting diode panel. Preferably, the second display device includes a liquid crystal display. Alternatively, the second display device includes an organic light-emitting diode display or a MicroLED display.

[0034] Preferably, the display system further includes a third volume, wherein a third display device is located within the third volume, and the output surface further includes a third display block located within the third volume.

[0035] Optionally, the second volume is located between the first volume and the third volume. Optionally, the ineffective display area of ​​the second display device surrounds both sides of the effective display area.

[0036] The second light guide extends at least partially through the second volume and the third volume; wherein the second light guide couples light from the third display device to illuminate a portion of the second volume located between the ineffective display area and the second display block.

[0037] Alternatively, the first volume is located between the second volume and the third volume. Optionally, the third display device includes an effective display area surrounded by a non-effective display area.

[0038] The second light guide extends at least partially through the first volume and the third volume; wherein the second light guide couples light from the first display device to illuminate a portion of the third volume located between the ineffective display area of ​​the third display device and the third display block.

[0039] By incorporating more light guides into a larger display system with three display devices, lighting can be created above other ineffective display areas within the display devices or system, thus creating an overall immersive display for the viewer.

[0040] According to a second aspect of the present invention, a method for manufacturing a display system is provided, the method comprising:

[0041] - Provides a first volume and a second volume;

[0042] - Provide an output surface, the output surface including a first display block located within the first volume and a second display block located within the second volume;

[0043] - Position the first display device within the first volume.

[0044] - Positioning a second display device within the volume, wherein the second display device includes an effective display area surrounded by a non-effective display area;

[0045] - Arrange an optical guide such that the optical guide at least partially extends through the first volume and the second volume; and

[0046] - Configure the light guide such that it couples light from the first display device to illuminate a portion of the second volume located between the ineffective display area and the output surface.

[0047] The second aspect of the invention may include features that implement the preferred or optional features of the first aspect of the invention, and vice versa.

[0048] According to a third aspect of the present invention, a display system is provided, the display system comprising:

[0049] First volume and second volume

[0050] The first volume includes a liquid crystal module having an effective display area and an ineffective display area for displaying images.

[0051] The second volume includes light-emitting diode (LED) light bricks for backlighting.

[0052] The second volume includes a light guide superimposed on the ineffective display area and the light-emitting diode (LED) light brick, such that some light from the LED light brick is guided to be emitted above the ineffective display area.

[0053] The third aspect of the invention may include features that implement the preferred or optional features of the first or second aspect of the invention, and vice versa. Attached Figure Description

[0054] Various embodiments of the invention will now be described by way of example only, in conjunction with the accompanying drawings, in which:

[0055] Figure 1 A side view of a display system according to an embodiment of the present invention is shown;

[0056] Figures 2-4 A side view of a display system according to an alternative embodiment of the present invention is shown;

[0057] Figure 5 A side view of a display system according to another alternative embodiment of the present invention is shown;

[0058] Figure 6 A side view of a display system according to another alternative embodiment of the present invention is shown;

[0059] Figure 7 A side view of a display system according to another alternative embodiment of the invention is shown; and

[0060] Figure 8 A side view of a display system according to another alternative embodiment of the present invention is shown.

[0061] In the following description, the same parts will be labeled with the same reference numerals throughout the specification and drawings. The drawings are not necessarily drawn to scale, and the proportions of some parts have been exaggerated to better illustrate the details and features of embodiments of the invention. DETAILED DESCRIPTION

[0062] Now combine Figures 1 to 8 Description of the present invention.

[0063] First refer to Figure 1 The figure illustrates a side view of a display system according to an embodiment of the present invention, which is generally indicated by reference numeral 1 in the reference numerals.

[0064] It can be seen that, Figure 1 The display system 1 shown includes a first volume 2 and a second volume 3, such as Figure 1 The area highlighted by the dashed line is shown. The first display device 4 is located within the first volume 2, and the second display device 5 is located within the second volume 3. The light output or display content from both the first display device 4 and the second display device 5 is directed to the output surface 6 of the display system 1.

[0065] The output surface 6 of the display system 1 includes a first display block 6a located within a first volume 2 and a second display block 6b located within a second volume 3. Thus, light output or display content from the first display device 4 is directed to the first display block 6a of the output surface 6, while light output or display content from the second display device 5 is directed to the second display block 6b of the output surface 6. As a result of this arrangement, the first volume 2 includes the first display device 4 and the first display block 6a, while the second volume 3 includes the second display device 5 and the second display block 6b.

[0066] exist Figure 1 In this design, the first display device 4 is a light-emitting diode (LED) panel, and the second display device 5 is a liquid crystal display (LCD) panel. However, as those skilled in the art will understand, any suitable display device can alternatively be used as the first display device 4 or the second display device 5. Examples of alternative types of display devices include organic light-emitting diode (OLED) and MicroLED devices.

[0067] The second display device 5 is shown to include an effective display area 7 and an ineffective display area 8, wherein the effective display area 7 is surrounded by the ineffective display area 8. The effective display area 7 of the second display device 5 includes a pixel array responsible for generating visual content for the second display device 5.

[0068] exist Figure 1 In the diagram, the inactive display area 8 is shown as surrounding only one side of the active display area 7. However, as those skilled in the art will understand, the inactive display area 8 may alternatively surround both or more sides of the active display area 7.

[0069] The inactive display area 8 of the second display device 5 typically includes photosensitive components required to operate the active display area 7 of the second display device 5, such as electrical connections and control circuit networks. Therefore, the inactive display area 8 is typically coated with an opaque black mask to provide protection for these photosensitive components. Due to the presence of the opaque black mask, no light is emitted from the inactive display area 8 of the second display device 5.

[0070] Figure 1 The display system 1 is also shown to include a diffuser 9. The diffuser 9 is positioned to extend from the first volume 2 to the second volume 3. The diffuser 9 is used to more uniformly scatter and distribute light on the output surface 6 of the display system 1. This helps to improve the viewer's visual quality and viewing experience. Figure 1 As can be seen, the diffuser 9 extends through the entire first volume 2, but only partially through the second volume 3. Specifically, the diffuser 9 extends only over the ineffective display area 8 of the second display device 5. As those skilled in the art will understand, the diffuser may alternatively be located at any other suitable location within the display system 1.

[0071] exist Figure 1 In this display system 1, a cover glass 10 is used to form the output surface 6 of the display system 1. The cover glass 10 spans the entire display system 1, that is, across both the first display block 6a and the second display block 6b, and is the outermost layer of the display system 1. The cover glass 10 provides protection for the display system 1. It is typically a transparent or translucent sheet of material used to cover and shield the components underneath, such as the first display device 4 and the second display device 5. The cover glass 10 also directly affects how the image is presented to the viewer of the display system 1. Therefore, the cover glass 10 is designed to minimize optical distortion and ensure high optical sharpness of the image displayed at the output surface 6 to provide a clear image to the viewer of the display system 1.

[0072] Figure 1 The display system 1 also includes a light guide 11. The light guide 11 extends from the first volume 2 to the second volume 3 and is located between the first display device 4, the second display device 5, and the output surface 6. The light guide 11 is designed to guide light via total internal reflection or other guiding mechanisms.

[0073] exist Figure 1 In this embodiment, the cladding 12 is disposed on the outer surface of the light guide 11. The cladding 12 does not extend over the entire light guide 11. Specifically, the cladding 12 is shown to exist only within the first volume 2 of the display system 1.

[0074] Generally, the refractive index of the material used for cladding 12 is lower than that of the light guide 11. In this way, light traveling within the light guide 11 in the first volume 2 is prevented from escaping or leaking out of the light guide 11. Cladding 12 helps ensure effective light propagation within the light guide 11 and prevents light loss from occurring in undesirable locations such as the first volume 2.

[0075] Figure 1 The position of the light guide 11 allows light emitted from the first display device 4 within the first volume 2 to be coupled into the light guide 11. The light guide 11 can then guide the coupled light from the first volume 2 to the second volume 3.

[0076] The light guide 11 may comprise a transparent material such as optical fiber or glass. The light guide 11 is configured to couple light from a first volume 2 into a second volume 3 using light guiding methods such as total internal reflection (TIR) ​​and refraction. Generally, light entering the light guide 11 at one end enters the interface between the core and cladding 12 of the light guide 11 at an angle greater than the critical angle. This causes light reflection, and thus the light passes through the light guide 11 without escaping. By controlling the refractive index, geometry, and coating of the light guide 11, light propagation through the light guide 11 can be optimized, ensuring minimal loss and efficient optical coupling from the first volume 2 to the second volume 3.

[0077] exist Figure 1 In this configuration, the light guide 11 is arranged or positioned to provide illumination within a portion of the second volume 3. Specifically, Figure 1 The light guide 11 illuminates the portion of the second volume 3 located between the ineffective display area 8 of the second display device 5 and the second display block 6a of the output surface 6.

[0078] It should be noted that, Figure 1 The light guide 11 overlaps only a portion of the first volume 2, while the end of the light guide 11 coincides with the end of the ineffective display area 8 within the second volume 3. However, as those skilled in the art will understand, the position of the light guide 11 is not fixed. Figure 1 The position shown can be used to reposition the light guide as long as the light guide 11 still overlaps with both the first volume 2 and the second volume 3.

[0079] In existing display systems that do not include the aforementioned light guide 11, the ineffective display area 8 of the second display device 5 results in an opaque boundary between the first display device 4 and the second display device 5. Specifically, viewers of this system will observe a noticeable opaque boundary between the first display block 6a and the second display block 6b on the output surface 6. However, by including the light guide 11 within the display system 1 of the present invention, the illumination provided within the second volume 3 causes viewers of the display system 1 to no longer observe the opaque boundary between the first display block 6a and the second display block 6b. Instead, a more natural lighting transition is provided between the first display block 6a and the second display block 6b. Therefore, compared to existing systems, the aforementioned display system 1 can produce a more immersive display for the user.

[0080] Figure 1 The display system 1 may also include a reflector 13 located between the light guide 11 and the ineffective display area 8 of the second display device 5. The reflector 13 can be used to improve the optical performance of the display system 1. Specifically, the reflector 13 is used to reflect light that would otherwise be lost or scattered within the second volume 3 and redirect it to the second display block 6b of the output surface 6 of the display system 1. In this way, the amount of light providing illumination to the ineffective display area 8 can be increased.

[0081] Figure 2 , Figure 3 and Figure 4 An alternative display system 14 was presented.

[0082] Figures 2-4 The display system 14 presented in the middle is related to the above about Figure 1 The main difference between the described display systems 1 lies in the shape of the light guide 11.

[0083] exist Figure 1In the display system 1, the light guide 11 is a standard two-dimensional light guide 11. In this way, the shape of the light guide 11 provides confinement of light waves in two dimensions and is designed to distribute light uniformly on the two-dimensional plane.

[0084] exist Figure 2 In the display system 14a, the light guide 11 is a three-dimensional light guide 11. The advantage of using such a three-dimensional light guide 11 is that it can result in improved optical performance and improved illumination on the ineffective display area 8 of the second display device 5.

[0085] exist Figure 3 and Figure 4 In display systems 14b and 14c, the light guide 11 is a 2.5-dimensional light guide 11. Figure 2 Similar to the optical guide 11, this shape can lead to improved optical performance when compared to conventional two-dimensional optical guides.

[0086] Figure 2 , Figure 3 and Figure 4 Such an example of a light guide 11 is considered to be a thin optical lens or wedge with a flat surface, an inclined surface or a curved surface, depending on the target viewing angle and the characteristics of the first display device 4, the second display device 5 and the ineffective display area 8.

[0087] As those skilled in the art will understand, any suitable 2.5-dimensional or 3-dimensional shape can be used within the display system 14 to replace [the shape / shape]. Figure 2 , Figure 3 and Figure 4 Those shapes shown. Figures 2-4 The optical guides 11 are positioned directly below the diffuser 9; however, as those skilled in the art will understand, they can also be positioned independently of the diffuser 9, such as... Figure 1 The display system 1 is shown.

[0088] Figure 5 Another alternative display system 15 is illustrated. Figure 5 In this system, the optical guide 11 is integrated into the diffuser 9. To improve the optical performance of the display system 15, it may be necessary to combine the light guiding function and the light diffuser function into a single component. This integration allows light to be transmitted efficiently along the desired path, while also achieving a uniform and even distribution of light on the surface.

[0089] As those skilled in the art will understand, the integration of the light guide 11 and the diffuser 9 can be achieved through careful design and manufacturing techniques. The specific integration method and materials depend on the desired optical properties, the size and shape of the light guide 11, the optical properties of the diffuser 9, and the overall efficiency of light transmission and diffusion.

[0090] As those skilled in the art will understand, with Figure 2 , Figure 3 and Figure 4 Similar to the embodiment shown, alternative light guide shapes can be used for integrating light guide 11. Furthermore, with... Figure 1 Similar to the implementation scheme, the display system 15 may also include a reflector 13 located between the integrated light guide 11 and the ineffective display area 8 of the second display device 5 to further improve optical performance.

[0091] Figure 6 A display system 16 according to another alternative embodiment of the invention is presented. Figure 5 The implementation scheme is similar, and the display system 16 includes a diffuser 9 with an integrated light guide 11.

[0092] However, in Figure 6 In this display system 16, a three-dimensional cover glass 10 is used. The three-dimensional cover glass 10 is formed around the diffuser 9 and the light guide 11. The advantage of forming the cover glass around the diffuser 9 and the light guide 11 is that it can improve the optical performance of the display system 16 by providing viewers of the display system 16 with a more immersive and visually appealing user experience.

[0093] Those skilled in the art should understand that, for Figure 1 and Figures 2-4 The illustrated implementation scheme, i.e., for the individual (non-integrated) light guide 11 and diffuser 9, can also employ a similar technique of forming a three-dimensional cover glass 10 around the diffuser 9 and light guide 11.

[0094] Figure 7 A display system 17 according to another alternative embodiment of the present invention is presented. The display system 17 includes a first volume 2, a second volume 3, and a third volume 18, which respectively include a first display device 4, a second display device 5, and a third display device 19. Furthermore, the output surface 6 of the display system includes a first display block 6a, a second display block 6b, and a third display block 6c respectively located within the first volume 2, the second volume 3, and the third volume 18. Each of the first volume 2, the second volume 3, and the third volume 18 is composed of… Figure 7 The block shown is represented by the dashed line.

[0095] Traditional display devices (such as LCDs) have opaque borders around the display device, resulting in ineffective display areas on each side of the display device. Figure 7 This is illustrated in the example, wherein the second display device 5 has both a first ineffective display area 8a and a second ineffective display area 8b.

[0096] As a result, a second light guide 11b is included within the display system 17, extending from the third volume 18 to the second volume 3. The second light guide 11b is located above the third display device 19 and the second display device 5. As in the previous embodiment, the first light guide 11a extends from the first volume 2 to the second volume 3 and is located above the first display device 4 and the second display device 5.

[0097] The position of the first light guide 11a allows light emitted from the first display device 4 to be coupled into the first light guide 11a within the first volume 2. The light is then guided from the first volume 2 to the second volume 3. Specifically, the first light guide 11a is positioned to provide illumination to the first ineffective display area 8a of the second display device 5.

[0098] The second light guide 11b is positioned such that light emitted from the third display device 19 within the third volume 18 can be coupled into the light guide 11b. The light is then guided from the third volume 18 to the second volume 3. Specifically, the second light guide 11b is positioned to provide illumination to the second ineffective display area 8b of the second display device 5.

[0099] It should be noted that, in Figure 7 There are two diffusers 9a and 9b. The first diffuser 9a extends through the first volume 2 and the second volume 3, while the second diffuser 9b extends through the second volume 3 and the third volume 18. In addition, the first light guide 11a and the second light guide 11b are each shown having an associated outer cladding 12a and an outer cladding 12b.

[0100] Because light guides 11a and 11b provide illumination to the ineffective display areas 8a and 8b, viewers of the display system 17 will not observe opaque boundaries at the output surface 6 between the first display block 6a, the second display block 6b, and the third display block 6c. Therefore, even with multiple ineffective display areas 8, the display system 17 can produce a more immersive display for the user.

[0101] Figure 8 A display system 20 according to another alternative embodiment of the invention is presented. Figure 7 Similarly, the display system 20 includes a first volume 2, a second volume 3, and a third volume 18, which respectively include a first display device 4, a second display device 5, and a third display device 19. However, in Figure 8 In the middle, the first volume 2 is located between the second volume 3 and the third volume 18.

[0102] exist Figure 8 In the second display device 5, there are effective display areas 7a and ineffective display areas 8a. Similarly, the third display device 19 also includes effective display areas 7b and ineffective display areas 8b.

[0103] As with the previous implementation, a first light guide 11a exists within the display system 20, extending from the first volume 2 to the second volume 3, and is located above the first display device 4 and the second display device 5.

[0104] Additionally, the display system 20 includes a second light guide 11b, which is positioned to extend from the first volume 2 to the third volume 18. The second light guide 11b is located above the first display device 4 and the third display device 19.

[0105] The positions of the first light guide 11a and the second light guide 11b are such that some light emitted from the first display device 4 can be coupled into both the first light guide 11a and the second light guide 11b. Then, the coupled light from the first display device 4 is guided from the first volume 2 to the second volume 3 through the first light guide 11a, and from the first volume 2 to the third volume 18 through the second light guide 11b.

[0106] The first light guide 11a is arranged to illuminate a portion of the second volume 3. Specifically, the first light guide 11a illuminates the portion of the second volume 3 located between the ineffective display area 8a of the second display device 5 and the second display block 6b of the output surface 6.

[0107] The second light guide 11b is arranged to illuminate a portion of the third volume 18. Specifically, the second light guide 11b illuminates the portion of the third volume 18 located between the ineffective display area 8b of the third display device 19 and the third display block 6b of the output surface 6.

[0108] It should be noted that, in Figure 8 In the middle, a single diffuser 9 extends through each of the first display block 2, the second display block 3, and the third display block 18.

[0109] This assembly of the display system 20 again provides an immersive display for the viewer of the display system 20. This is because this assembly makes the peripheries of the first display device 4 and the third display device 19 no longer appear opaque to the viewer of the display system 20. Therefore, even if there is more than one display device including an ineffective display area 8, the aforementioned display system 17 can produce a more immersive display for the user.

[0110] Figure 7 and Figure 8 The implementation scheme shows that has Figure 1 The display systems 17 and 20 are of the type shown, including light guides 11a and 11b, diffusers 9a and 9b, and cladding layers 12a and 12b. However, as those skilled in the art will understand, Figure 7 and Figure 8Display system 17 and display system 20 can be modified to include a combination Figures 2-4 , Figure 5 and Figure 6 The described display system 14, display system 15 and display system 16, or any combination thereof.

[0111] In summary, this invention provides an alternative display system to known display systems in the art, which improves the illumination transition between different display devices.
