Furthermore, element symbols and / or letters may be repeated in various examples of the present utility model. This repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or configurations discussed.

[0054] It should be understood that although the terms "first," "second," "third," etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part.

[0055] Please see Figure 1 , Figure 1 This is a schematic diagram of a display device 100 according to one embodiment of the present invention. In some embodiments, the display device 100 includes a housing 110, a light source 120, a frame 130, a first light-shielding element 140, a second light-shielding element 150, a light guide plate 160, an optical sheet module 170, a display screen module 180, and a connecting element 200.

[0056] exist Figure 1 In this structure, a first light-shielding element 140 is disposed between the frame 130 and the light guide plate 160, and has a first side 141 and a second side 142 facing each other. A second light-shielding element 150 is disposed between the frame 130 and the optical sheet module 170. A light source 120 is located on the first side 141 of the first light-shielding element 140. The optical sheet module 170 is located on the second side 142 of the first light-shielding element 140. A connecting element 200 connects the frame 130 and the first light-shielding element 140, and includes an opening 220. The opening 220 is located away from the first side 141 of the first light-shielding element 140 and adjacent to the second side 142 of the first light-shielding element 140.

[0057] In some embodiments, the frame 130 may be a flexible plastic frame with a certain degree of elasticity that can deform slightly as needed to adapt to the connection and fixation with the housing or to the load-bearing capacity of the display screen module 180.

[0058] In some embodiments, the first light-shielding element 140 and the second light-shielding element 150 may be made of polymer materials, such as rubber or poron. The first light-shielding element 140 is located above the light guide plate 160 and disposed between the light source 120 and the optical sheet module 170 to block light emitted from the light source 120 that does not enter the light guide plate 160, thereby preventing light leakage. The second light-shielding element 150 is disposed between the frame 130 and the optical sheet module 170 to prevent light not blocked by the first light-shielding element 140 from leaking through the gap between the frame 130 and the optical sheet module 170.

[0059] In some embodiments, the optical plate module 170 may include elements such as a diffuser and a brightness enhancement film to make the light emitted from the light guide plate more uniform and improve the light utilization efficiency to increase brightness. The display screen module 180 may include elements such as a front polarizer, a liquid crystal layer, and a rear polarizer to adjust the polarization direction of the light entering the liquid crystal layer, thereby controlling the transmitted light and affecting the visible image.

[0060] In some implementation methods, please refer to Figure 1 The first light-shielding element 140 is connected to the frame 130 via the connecting element 200, and the first light-shielding element 140 contacts the light guide plate 160. When the frame 130 is not deformed, the connecting element 200 is under balanced forces and can remain relatively stationary with respect to the first light-shielding element 140 and the frame 130. When the frame 130 is not deformed, the connecting element 200 applies a force to the first light-shielding element 140 in the direction of the light guide plate 160. In some embodiments, the magnitude of this force may be zero.

[0061] Please see Figure 2 , Figure 2 yes Figure 1 This is a schematic diagram of the display device 100 when the frame 130 is deformed. In some embodiments, the frame 130 may be deformed and turned outward due to physical factors (such as uneven screw torque at different locations, uneven distribution or magnitude of interaction forces between the frame and the outer casing, or other external forces). For example, the end of the frame 130 near the display screen module 180 may warp away from the light guide plate 160.

[0062] exist Figure 2 As can be seen, when the frame 130 warps away from the light guide plate 160 at the end near the display screen module 180 due to deformation, the opening 220 of the connecting element 200 relative to... Figure 1With the opening angle θ, the side of the connecting element 200 connected to the frame 130 can move with the frame 130, while the side connected to the first light-shielding element 140 remains in the same position and is unaffected. Due to the special material and structure of the connecting element 200, when the material of the connecting element 200 is relatively soft or thin, the force at its connection with the frame 130 will not affect the force with the first light-shielding element 140. When the material of the connecting element 200 has a certain thickness or hardness, stress will be generated in the connecting element 200 during the bending process of the "U"-shaped structure, and the stress will be released during the opening of the opening 220. Therefore, at a certain opening angle θ, the connecting element 200 will exert a force on the first light-shielding element 140 towards the light guide plate 160, keeping the first light-shielding element 140 stationary relative to the light guide plate 160.

[0063] Please see Figure 3A , Figure 3A A side view of a connecting element 200 in one embodiment, when unfolded, is shown. Figure 3A In this design, the connecting element 200 includes a flexible substrate 210, an adhesive layer 230, and a seam 240. The adhesive layer 230 is disposed on one side of the flexible substrate 210. The connecting element 200 adheres to the frame 130 and the first light-shielding element 140 via the adhesive layer 230. The connecting element 200 can be bent (e.g., folded in half) along the seam 240, so that the side without the adhesive layer 230 is facing each other as the inside, and the side with the adhesive layer 230 is the outside, to adhere the frame 130 and the first light-shielding element 140 (please refer to the accompanying documentation). Figure 1 ).

[0064] In some embodiments, the connecting element 200 may be a single-sided adhesive. In other embodiments, if the flexible substrate 210 is made of a material that facilitates bending, the seam 240 may be omitted, and the flexible substrate 210 may be bent directly. In some embodiments, the flexible substrate 210 may be made of a polymer material, such as polyethylene terephthalate (PET).

[0065] Please see Figure 3A' , Figure 3A' yes Figure 3A The diagram shows the connecting element 200 when bent. In other words, in this type of embodiment, commercially available single-sided tape can be used directly as the flexible substrate 210 and the adhesive layer 230, simplifying the manufacturing process of the connecting element 200.

[0066] Please see Figure 3B , Figure 3B A side view of the connecting element 200 in another embodiment when bent is shown. Figure 3BIn the process, the connecting element 200 includes a flexible substrate 210, an adhesive layer 230, and a seam 240. The flexible substrate 210 includes a first portion 211 and a second portion 212. The first portion 211 has a first connecting end 2112 and a first open end 2110 opposite each other. The second portion 212 has a second connecting end 2122 and a second open end 2120 opposite each other. The first connecting end 2112 connects to the second connecting end 2122, and the first open end 2110 and the second open end 2120 are farther away from the light source 120 than the first connecting end 2112 and the second connecting end 2122 (please refer to the accompanying documentation). Figure 1 ).

[0067] exist Figure 3B In the process, the flexible substrate 210 is bent along the seam 240, so that the first part 211 and the second part 212 are opposite each other, and an opening 220 is formed between the first open end 2110 and the second open end 2120.

[0068] exist Figure 3B In, with Figure 3A The difference is that the adhesive layer 230 includes a separate first adhesive layer 231 and a second adhesive layer 232. The first adhesive layer 231 is disposed on the first portion 211 and configured to adhere to the frame 130, and the second adhesive layer 232 is disposed on the second portion 212 and configured to adhere to the first light-shielding element 140. The side of the first portion 211 without the first adhesive layer 231 and the side of the second portion 212 without the second adhesive layer 232 are opposite to each other.

[0069] Please see Figure 3C , Figure 3C yes Figure 3B Front view of connecting element 200. Figure 3C In this configuration, after the opening 220 is opened, an angle θ is formed between the first portion 211 and the second portion 212. In some embodiments, the angle θ may be less than 20 degrees, less than 10 degrees, or between 10 and 20 degrees. The first portion 211 of the connecting element 200 connects to the frame 130, and the second portion 212 connects to the light-shielding element 140. When the angle θ after the opening 220 is opened remains less than 20 degrees, the relative movement of the first portion 211 and the relative stillness of the second portion 212 of the connecting element 200 can be ensured. This avoids the situation where the second portion 212 cannot remain relatively still and moves with the first portion 211 when the opening 220 is over-opened, thereby preventing the position of the first light-shielding element 140 from shifting.

[0070] Please see Figure 4A and Figure 4B The diagrams show cross-sectional views of the connecting element 200 according to other embodiments of the present invention. Figure 4AIn this process, the first adhesive layer 231 and the second adhesive layer 232 are separated, and the width W1 of the first adhesive layer 231 may be the same as or different from the width W2 of the second adhesive layer 232. For example, the width W1 of the first adhesive layer 231 may be greater than the width W2 of the second adhesive layer 232, thereby increasing the adhesive force between the connecting element 200 and the frame 130 and preventing the adhesive between the connecting element 200 and the frame 130 from loosening.

[0071] In some embodiments, since the materials of the first adhesive layer 231 and the second adhesive layer 232 are mostly compressible (flowable) and their thickness is difficult to control, the thickness of the connecting element 200 can be changed by changing the thickness of the flexible substrate 210 if different internal structure settings are required.

[0072] Please see Figure 4B The connecting element 200 includes a flexible substrate 210, a first adhesive layer 231 and a second adhesive layer 232. In addition to the connected first part 211 and second part 212, the flexible substrate 210 also includes a thickened layer disposed on the first part 211 and / or the second part 212, so that the flexible substrate 210 can locally thicken the first part 211 and / or the second part 212 according to different internal structure requirements.

[0073] For example, the flexible substrate 210 further includes a first thickening layer 251 disposed on the first portion 211 and a second thickening layer 252 disposed on the second portion 212. The first thickening layer 251 is disposed between the first adhesive layer 231 and the first portion 211, and is connected to the first portion 211. The second thickening layer 252 is disposed between the second adhesive layer 232 and the second portion 212, and is connected to the second portion 212. The materials of the first thickening layer 251 and the second thickening layer 252 may be the same or different from the materials of the first portion 211 and the second portion 212. The thicknesses of the first thickening layer 251 and the second thickening layer 252 may be the same or different. In some embodiments, it may be possible to use only the first thickening layer 251 or the second thickening layer 252, without having to provide both simultaneously.

[0074] In some embodiments, the first adhesive layer 231 and the second adhesive layer 232 have different viscosities. For example, the viscosity of the second adhesive layer 232 is greater than that of the first adhesive layer 231 because the material of the first light-shielding element 140 is less likely to adhere to the frame 130.

[0075] In summary, this utility model provides a display device. The display device has a movable connecting element between the frame and the light-shielding element. The connecting element has a first part and a second part connected at one end. The first part and the second part are respectively bonded to the frame and the light-shielding element. The opening between the first part and the second part faces the side opposite to the light source to prevent light leakage caused by deformation of the frame.

[0076] The foregoing summary outlines the features of several embodiments, enabling those skilled in the art to better understand the nature of this invention. Those skilled in the art will understand that they can readily use this invention as the basis for designing or modifying other processes and structures to achieve the same purpose and / or attain the same advantages of the embodiments described herein.
