Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a low-cost, compact dual-screen display device. Background Technology

[0002] In existing technologies, the display screens of devices such as vehicle infotainment systems, central control units, instrument panels, navigation systems, and home appliances are designed with different solutions due to varying functional requirements. For example, an instrument panel only needs to display information and does not require touch control; while a central control screen needs to combine display, touch control, privacy protection, and anti-glare features. This approach of using independent designs for different functional requirements results in an increased overall space occupied by the equipment and increases production complexity and manufacturing cycle. Utility Model Content

[0005] This application provides a low-cost, compact dual-screen display device, comprising: a cover plate, VBH foam, an OCA layer, a glass layer, and a BL dual-screen assembly structure;

[0006] The BL dual-screen assembly structure includes the BL frame, the first lower iron frame, and the second lower iron frame. The BL frame is an integral design.

[0007] The glass layer includes a first glass and a second glass, which correspond to the first lower iron frame and the second lower iron frame, respectively. The two glass pieces are used to be assembled with BL at the same time.

[0008] The OCA layer includes a first transparent adhesive and a second transparent adhesive, which correspond to the first glass and the second glass, respectively.

[0009] The BL frame is surrounded by a ring of VBH foam. The VBH foam includes a first foam and a second foam, which correspond to the first glass and the second glass, respectively.

[0010] Finally, the cover plate is attached and fixed.

[0011] Compared with the prior art, the beneficial effects of the embodiments of this application are:

[0012] This application provides a low-cost, compact dual-screen display device that combines two screens (which may have the same or different functions) to achieve a more compact design space and significantly reduced processing and assembly costs. Attached Figure Description

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] To illustrate the technical solution described in this application, specific embodiments are provided below.

[0028] Please see Figures 1 to 8 As shown, in order to solve the problems existing in the prior art, this application provides a low-cost, compact dual-screen display device. For different sizes and functional requirements, two screens can be integrated together according to the requirements of the end customer, thereby saving design space and manufacturing costs.

[0029] This application provides a low-cost, compact dual-screen display device, comprising: an explosion-proof film 11, a cover plate 12, VBH foam 13, an OCA layer 14, a glass layer 15, and a BL dual-screen assembly structure 16.

[0030] Specifically, please refer to Figure 1 As shown, the BL dual-screen assembly structure 16 serves as the BL light-emitting carrier and includes a BL frame 163, a first lower iron frame 161, and a second lower iron frame 162. The BL frame 163 is a single, integrated design.

[0031] In some embodiments, in the BL structural design, the lower iron frame, light guide plate, membrane material, and light strip are the same as in the single BL design.

[0032] Specifically, please refer to Figure 2 As shown, the size and function of the glass layer 15 can be selected according to customer needs, and this embodiment does not impose specific limitations.

[0033] In this embodiment, the glass layer 15 includes a first glass 151 and a second glass 152, which are used to be assembled with BL simultaneously.

[0034] Specifically, please refer to Figure 3 As shown, the OCA layer 14 is designed the same as the single module.

[0035] In some embodiments, the OCA layer 14 may be assembled with the cover plate 12 first. In other embodiments, the OCA layer 14 may be applied after the BL and glass layer 15 are assembled.

[0036] In some embodiments, the OCA layer 14 includes a first transparent adhesive 141 and a second transparent adhesive 142, which are optically transparent adhesives.

[0037] Specifically, please refer to Figure 4 and Figure 5 As shown, the BL frame 163 has an added ring-shaped VBH foam 13 on its four sides to solve the problem of light transmission around the glass and to increase the area after the cover plate 12 is bonded to the module. This can effectively solve the problem of whitening around the glass caused by pressure (caused by the compression of the liquid crystal core).

[0038] In some embodiments, VBH foam 13 includes a first foam 131 and a second foam 132.

[0039] Specifically, please refer to Figure 6 As shown, the cover plate 12 is finally bonded together. The overall design of the cover plate 12 of the two screens is achieved by nesting VA ink with glass AA to achieve bonding and positioning.

[0040] In some embodiments, alignment can be achieved by aligning the edge dimensions.

[0041] In summary, the low-cost, compact dual-screen display device provided in this application has the following advantages:

[0042] This effectively improves the compactness of the overall module assembly and design space, winning customer approval;

[0043] Accelerate the progress of client-side experimental testing and save costs;

[0044] Expedite the confirmation process with end customers to buy time for mass production.

[0045] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
