Description
Technical Field
The present disclosure relates to a display device, and more particularly, to a display device having a frame structure with an oblique convex structure.
Background
The display device mainly comprises a backlight module, a frame body, a display panel and other components. The frame body is provided with a protruding part extending inwards for supporting the display panel and maintaining the distance between the optical diaphragm and the display panel, and an elastic rubber is adhered to the contact surface of the protruding part and the optical diaphragm, so that the protruding part can be prevented from contacting and rubbing to scratch the optical diaphragm, and the optical diaphragm can be pressed to avoid warping of the optical diaphragm.
However, in the display device, due to the requirement of a narrow frame and the design of a full plane, the length of the inward extension of the protruding portion of the frame body is shortened, so that the overlapping area of the protruding portion and the optical film is relatively reduced, and therefore the elastic rubber on the protruding portion is located at the position of the cut edge of the optical film. The optical film at the edge of the corner of the display device is clamped to the elastic rubber due to dislocation displacement and can not return to the original position after the display device is carried or because the optical film expands with heat and contracts with cold, so that a circular arc-shaped ripple (waving) phenomenon is formed. Furthermore, in order to avoid the optical film from being stuck and the thickness of the elastic rubber is reduced, the elastic rubber has no pressing force on the optical film, and the optical film is easily warped to form a curtain-shaped corrugation phenomenon with poor brightness.

In an embodiment, the first maximum cut depth of the first oblique groove is smaller than the second maximum cut depth of the second oblique groove and the third maximum cut depth of the third oblique groove, so that the outward convex thickness of the oblique convex structure corresponding to the buffer strip located in the first oblique groove is greater than the outward convex thickness of the oblique convex structure corresponding to the buffer strip located in the second oblique groove and the outward convex thickness of the oblique convex structure corresponding to the buffer strip located in the first oblique groove.

In one embodiment, the first inclined angle gradually decreases to a second inclined angle between the first inclined groove and the second inclined groove, and the first inclined angle gradually decreases to a third inclined angle between the first inclined groove and the third inclined groove.
The scheme utilizes the design of slant recess to change the angle and the degree of depth of buffering strip to control the relative distance between optical diaphragm and the buffering strip, cooperates the oblique protruding structure that the buffering strip formed again, not only can provide optical diaphragm clamping force, can avoid buffering strip card to optical diaphragm even more.

Detailed Description
Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure, and please refer to fig. 1, the display device 10 mainly includes a backlight module 12, a display panel 14, a diffuser plate 16, a quantum dot film 18, an optical film 20, and a frame structure 30. The lowermost backlight module 12 is located between the frame structures 30, a diffusion plate 16, a quantum dot film 18 and an optical film 20 are sequentially disposed above the backlight module 12 from bottom to top, and the display panel 14 is located above the optical film 20, so that the frame structures 30 are used to support the display panel 14 and position the optical film 20. The frame structure 30 includes a frame 32 and at least one buffer strip 34, and a protrusion 36 extends inward from at least one side of the frame 32, and in this embodiment, the opposite sides of the frame 32 are taken as an example, but not limited thereto. A protrusion 36 extends inward from each of two sides of the frame 32, and the protrusion 36 is located right above the edge of the optical film 20 and has a partial overlap, and a fixed gap is maintained between the diffusion plate 16, the quantum dot film 18, and the optical film 20 and the frame 32. The display panel 14 is located in the frame 32 and disposed on the protrusion 36, so as to support the display panel 14 by the protrusion 36 and maintain a proper distance between the optical film 20 and the display panel 14.
In one embodiment, the optical film 20 includes a reflective polarizing incremental film (DBEF) and a prism sheet.
In the frame structure 30, an inclined groove 38 is provided on the surface of the protrusion 36 close to the optical film 20, and a chamfered bottom surface 384 in the inclined groove 38 is farther from the optical film 20 as it goes toward the center of the frame 32. At least one buffer strip 34 is disposed in the slanted groove 38, so that the slanted groove 38 fixes the buffer strip 34 in an oblique direction, and the buffer strip 34 forms a slanted convex structure 341 by protruding a part of the buffer strip 34 out of the surface in cooperation with the design of the slanted groove 38, so as to position the optical film 20 by using the slanted convex structure 341. The inclination angle of the beveled bottom surface 384 of the inclined groove 38 or the maximum cut depth of the inclined groove 38 can be used to adjust the position and angle of the buffer strip 34 (the inclined convex structure 341), so as to prevent the optical film 20 from being stuck, and adjust the distance between the buffer strip 34 and the optical film 20 to control the deformation degree of the pressed optical film 20.
In one embodiment, the buffer strip 34 is an elastic rubber strip.
In addition, in order to firmly fix the buffer strip 34 in the inclined groove 38, an adhesion element (not shown) is disposed on the chamfered bottom surface 384 of the inclined groove 38 to adhere the buffer strip 34 in the inclined groove 38. In one implementation, the following element is a double-sided adhesive.
Fig. 2 and 3 are partial schematic structural views of frame structures with different maximum cut depths, respectively, please refer to fig. 2 and 3. As shown in the frame structure 30 of fig. 2, when the maximum depth x of the inclined groove 38 is greater than the thickness H of the buffer strip 34 (x > H), since most of the buffer strip 34 is accommodated in the inclined groove 38, it is necessary to ensure that the buffer strip 34 has the protruding inclined convex structure 341, so the convex thickness y of the inclined convex structure 341 must be greater than 0, which can be expressed as the convex thickness y ═ Hcos θ - (x-H) cos θ >0, where H represents the thickness of the buffer strip 34, θ represents the inclination angle of the buffer strip 34, and x represents the maximum depth of the inclined groove 38. After the convex thickness y of the slanted convex structure 341 is obtained, the relative distance m between the buffer bar 34 and the optical film 20 can be calculated, where m is z-y, where z represents the distance between the convex portion 36 and the optical film 20, and y represents the convex thickness of the slanted convex structure 341. In one embodiment, the relative distance m between the buffer bar 34 and the optical film 20 is a fixed design value, and the value thereof may range from 0.2mm to 0.6mm, but is not limited thereto, and may vary according to the actual requirement.
As shown in the frame structure 30 of fig. 3, when the maximum depth x of the cut of the inclined groove 38 is smaller than the thickness H of the buffer bar 34 (x < H), in order to avoid the buffer bar 34 from blocking the optical film 20, the thickness D of the side of the buffer bar 34 exposed out of the inclined groove 38 is smaller and better, and the maximum thickness D cannot exceed half of the thickness D of the optical film 20, that is, the thickness D of the side of the buffer bar 34 exposed out of the inclined groove 38 is smaller than half of the thickness D of the optical film 20, and the thickness D of the side can be represented as D ═ H-x) cos θ <0.5D, where H represents the thickness of the buffer bar 34, x represents the maximum depth of the cut of the inclined groove 38, θ represents the inclination angle of the buffer bar 34, and D represents the thickness of the optical film 20.
As shown in fig. 2 and 3, the frame structure 30 (fig. 2) having a larger maximum notch depth x of the inclined groove 38 has a larger relative distance m between the buffer strip 34 and the optical film 20, while the distance between the protrusion 36 and the optical film 20 is kept constant. The frame structure 30 (fig. 3) having a smaller maximum cut depth x of the slanted groove 38 has a relatively smaller relative distance m between the buffer strip 34 and the optical film 20, so that the relative distance m between the buffer strip 34 and the optical film 20 can be adjusted by changing the maximum cut depth x of the slanted groove 38.
Fig. 4 and 5 are schematic partial structural diagrams of frame structures with different inclination angles, respectively, please refer to fig. 4 and 5, because the buffer bar 34 is disposed in the inclined groove 38, the beveled bottom surface 384 in the inclined groove 38 is parallel to the mounting side surface of the buffer bar 34, and the beveled bottom surface 384 in the inclined groove 38 has an inclination angle, the buffer bar 34 also has an inclination angle θ correspondingly, and the inclination angle of the beveled bottom surface 384 in the inclined groove 38 is equal to the inclination angle θ of the buffer bar 34. In one embodiment, the inclination angle θ is between 10 degrees and 45 degrees. On the premise that the distance between the protrusion 36 and the optical film 20 is kept constant, as shown in fig. 4, the frame structure 30 has a larger inclination angle θ of the buffer bar 34, and the inclined protrusion 341 of the buffer bar 34 protruding from the lower surface of the protrusion 36 is also larger, so the relative distance m between the buffer bar 34 and the optical film 20 is relatively smaller. As shown in fig. 5, the frame structure 30 has a smaller inclination angle θ of the buffer bar 34, and since the inclined convex structure 341 of the buffer bar 34 protruding from the lower surface of the convex portion 36 is smaller, the relative distance m between the buffer bar 34 and the optical film 20 is relatively larger, the relative distance m between the buffer bar 34 and the optical film 20 can be adjusted by changing the inclination angle of the chamfered bottom surface 384 of the inclined groove 36 (the inclination angle θ of the buffer bar 34).
For the same inclined groove 38 on the protrusion 36 on one side of the frame 32, the relative distance between the buffer strip 34 and the optical film 20 can be adjusted according to different positions, so that the buffer strips 34 in the same inclined groove 38 have different convex thicknesses of the inclined convex structures 341 at the same time. As shown in fig. 1 and fig. 6, the slanted groove 38 is further divided into a first slanted groove 381 located in the middle region, and a second slanted groove 382 and a third slanted groove 383 located on both sides of the first slanted groove 381. In an embodiment, for the same slanted groove 38 on the protrusion 36 on one side of the frame 32, the relative distance between the same buffer bar 34 and the optical film 20 at different positions can be adjusted by changing the maximum notch depth of the slanted groove 38, as shown in fig. 1 and fig. 6, the first maximum notch depth x1 of the first slanted groove 381 is smaller than the second maximum notch depth x2 of the second slanted groove 382 and the third maximum notch depth x3 of the third slanted groove 383, and the second maximum notch depth x2 of the second slanted groove 382 can be equal to the third maximum notch depth x3 of the third slanted groove 383, and since there are two sets of maximum notch depths in the same slanted groove 38, the same buffer bar 34 in the same slanted groove 38 will have different outward protruding thicknesses of the slanted protruding structures 341 at the same time, that is, the outward protruding thickness of the corresponding to the slanted protruding structure 34 in the first slanted groove 381 is greater than the outward protruding thickness of the buffer bar 34 in the second slanted groove 382 on the left side The convex thickness of the corresponding inclined convex structure 341 and the convex thickness of the corresponding inclined convex structure 341 of the buffering strip 34 in the right third inclined groove 383. Therefore, the buffer bar 34 located in the middle region (the first inclined groove 381) can be closer to the optical film 20 to provide sufficient pressing force for the optical film 20, while the buffer bars 34 located in the side regions (the second inclined groove 382 and the third inclined groove 383) are kept at a proper relative distance from the optical film 20 to allow the optical film 20 to smoothly enter and exit without being stuck.
In an embodiment, referring to fig. 6, fig. 7 and fig. 8, one side of the optical film 20 further includes a protrusion 201, in this embodiment, two opposite sides of the optical film 20 include a plurality of protrusions 201, but not limited thereto, and the protrusion 201 may be disposed corresponding to a junction of the first slanted groove 381 and the second slanted groove 382, or the protrusion 201 may be disposed corresponding to a junction of the first slanted groove 381 and the third slanted groove 383 to serve as a buffer area to alleviate an influence of a structural difference at the junction. Since the first maximum notch depth x1 of the first slanted groove 381 is smaller than the second maximum notch depth x2 of the second slanted groove 382 and the third maximum notch depth x3 of the third slanted groove 383, the buffer strip 34 in the middle area can be closer to the optical film 20, as shown in fig. 7, and the relative distance m between the buffer strip 34 and the optical film 20 is relatively smaller, so that the buffer strip 34 with a larger protruding thickness in the middle area can be reliably pressed to the optical film 20 by cooperating with the lug 201, thereby preventing the optical film 20 from generating the moire phenomenon. The buffer bars 34 located at the second oblique groove 382 and the third oblique groove 383 in the two side regions are farther from the optical film 20, as shown in fig. 8, and the relative distance m between the buffer bars 34 and the optical film 20 is relatively larger, so as to prevent the buffer bars 34 from interfering with the optical film 20.
In one embodiment, as shown in fig. 9, between the first slanted groove 381 and the second slanted groove 382, the first maximum kerf depth x1 gradually increases to a second maximum kerf depth x2, and between the first slanted groove 381 and the third slanted groove 383, the first maximum kerf depth x1 gradually increases to a third maximum kerf depth x3 to provide a gradual maximum kerf depth.
For the same inclined groove 38 on the protrusion 36 on one side of the frame 32, the relative distance between the buffer strips 34 at different positions and the optical film 20 can be adjusted by changing the inclination angle of the chamfered bottom surface 384 of the inclined groove 38. As shown in fig. 1, 10 and 11, the chamfered bottom 381a of the first inclined groove 381 has a first inclination angle θ 1, the chamfered bottom 382a of the second inclined groove 382 has a second inclination angle θ 2, the chamfered bottom 383a of the third inclined groove 383 has a third inclination angle θ 3, the first inclination angle θ 1 is greater than the second inclination angle θ 2 and the third inclination angle θ 3, and the second inclination angle θ 2 may be equal to the third inclination angle θ 3, but not limited thereto. Because the same inclined groove 38 has different inclination angles, the same buffer strip 34 in the same inclined groove 38 has different inclination angles at the same time, so that the buffer strip 34 has different outward protruding thicknesses of the inclined convex structures 341 at the same time, that is, the outward protruding thickness of the inclined convex structure 341 corresponding to the buffer strip 34 located in the first inclined groove 381 is greater than the outward protruding thickness of the inclined convex structure 341 corresponding to the buffer strip 34 located in the second inclined groove 382 and the outward protruding thickness of the inclined convex structure 341 corresponding to the buffer strip 34 located in the third inclined groove 383. In one embodiment, the first inclination angle θ 1 gradually decreases to a second inclination angle θ 2 between the first inclined groove 381 and the second inclined groove 382, and the first inclination angle θ 1 gradually decreases to a third inclination angle θ 3 between the first inclined groove 381 and the third inclined groove 383 to provide a gradually changing inclination angle.
Since different positions of the same optical film 20 can have different relative distance requirements, the depth and the inclination angle of the cut of the inclined groove 38 can be changed according to different positions, so that the buffer strip 34 with the same thickness can be attached to different positions with different relative distances, the assembly is more convenient, and the material is quite cheap.
In one embodiment, as shown in fig. 12, the at least one buffer bar 34 further includes a first buffer bar 342, a second buffer bar 343, and a third buffer bar 344, the first buffer bar 342 is disposed in the first inclined groove 381, the second buffer bar 343 is disposed in the second inclined groove 382, the third buffer bar 344 is disposed in the third inclined groove 383, and the elastic modulus of the first buffer bar 342 is greater than the elastic modulus of the second buffer bar 343 and the elastic modulus of the third buffer bar 344, the elastic modulus of the second buffer bar 343 may be equal to the elastic modulus of the third buffer bar 344, such that the outward convex thickness of the slanted convex structure 341 corresponding to the first buffer bar 342 located in the first inclined groove 381 is greater than the outward convex thickness of the slanted convex structure 341 corresponding to the second buffer bar 343 located in the second inclined groove 382 and the outward convex thickness of the slanted convex structure 341 corresponding to the third buffer bar 344 located in the third inclined groove 383, so as to provide different pressing effects by using the first, second and third buffer strips 342, 343, 344 with different elastic coefficients, respectively. Therefore, the first buffer bar 342 located in the middle region (the first inclined groove 381) can be closer to the optical film 20 to provide sufficient pressing force for the optical film 20, while the second buffer bar 343 and the third buffer bar 344 located in the side regions (the second inclined groove 382 and the third inclined groove 383) are kept at a proper relative distance from the optical film 20 to allow the optical film 20 to smoothly enter and exit without being stuck.
Therefore, the buffering strip with the oblique convex structure can provide enough pressing force for the optical film to avoid the corrugation phenomenon, and when the optical film at the corner edge displaces due to dislocation in the process of carrying the display device or due to expansion and contraction of the optical film, the optical film can return to the original position along the oblique convex structure of the buffering strip and cannot be clamped by the buffering strip.
In addition, in order to make the protruding portion 36 of the frame 32 have an inclined slope, a special-shaped buffer strip may be provided on the lower surface of the protruding portion 36, as shown in fig. 13, a triangular buffer strip 40 is provided on the lower surface of the protruding portion 36, so as to provide an inclined slope by providing the triangular buffer strip 40, but this method needs to produce a special-shaped buffer strip, and since the buffer strip is produced in a roll, the special-shaped design needs to be processed and formed again, which results in high cost, unlike the structural design of the present application. As shown in fig. 14, the other way is to directly project the protrusion 36 of the frame body 32 from the bottom edge of the buffer strip 34 to directly form an inclined bevel 42 and abut the buffer strip 34, but this way requires the production of a frame body 32 with special specifications, so that the sharing of the frame body 32 is reduced. Moreover, the contact of the edge of the optical film 20 with the hard inclined bevel edge 42 is likely to generate friction and generate scraping, and the efficacy is not as good as the structural design of the present invention.
In conclusion, the design of the oblique groove is utilized to change the angle and the depth of the buffer strip so as to control the relative distance between the optical membrane and the buffer strip, and the oblique convex structure formed by the buffer strip is matched, so that the pressing force of the optical membrane can be provided, and the buffer strip can be prevented from being clamped on the optical membrane.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
