Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

At present, the main reason why black edges are formed in the manufacturing process of liquid crystal display screens is that the liquid crystal screens are composed of dot matrixes which are connected to an external control circuit through wires integrated on a panel, so that a wiring area of an integrated circuit is arranged at the edge of the screens, the wiring area cannot be eliminated, and part of the black edges are composed of the wiring area. Secondly, the black edge can prevent the screen from leaking light and shield the light from the backlight plate, and if the edge of the screen has no black edge, an obvious halo can be seen at the edge of the screen. In addition, a part of the edge of the panel is required to be occupied when the liquid crystal is packaged, and the sealing structure is also one of the reasons for forming the black edge. In summary, in the currently mainstream lcd, the black edge at the edge of the screen cannot be completely removed.

In the related art, the black edge of the screen is improved through the schemes of glass frameless, frame structure stacking optimization, display module edge structure optimization, a curved screen, edge optical reduction frames and the like. The specific scheme is as follows:

(1) the glass has no frame: the cover plate glass completely covers the screen and the frame, and the black edge and the frame of the screen are both covered under the glass cover plate. However, the display area when the screen is bright is smaller than the area of the glass cover plate, and a black edge still exists, which is not a true narrow frame or no frame.

(2) The frame structure is stacked and optimized: through optimizing the frame structure and piling up, hide the screen black border in the frame, realize not having the black border in the vision. The frame in the scheme needs to shield the black edge of the screen, and is often wider and poor in visual effect.

(3) Optimizing the edge structure of the display module: in the manufacturing process of the display panel, the black edge width of the edge of the display area is reduced by adjusting the packaging structure, optimizing the routing design and the like. However, such schemes only provide limited reduction of the black border width and do not completely eliminate the black border.

(4) A curved screen: the characteristic of flexibility and bendability of the curved screen is utilized, and the edge of the screen is designed to be bent or bent at a large angle, so that a frameless effect is realized. Such a scheme requires a high-cost flexible display technology, and due to the curvature of the screen, the picture displayed at the edge position is also curved, which affects the use of a part of the scene. In addition, the current mainstream flexible display technology can only realize 2-side bending, and the simultaneous bending of the upper side, the lower side, the left side and the right side of 4 sides is difficult to realize, so that no frame can be realized all around.

(5) Edge optical reduction frame: by using the optical effect, the frame and the screen black edge are visually reduced or completely eliminated. For example, the black edge is visually reduced by utilizing the refraction effect of the edge of the glass cover plate (similar to the lens principle), but the method only can reduce but can not completely eliminate the black edge, and the aberration phenomenon exists. Or, the screen display area is enlarged by using the Fresnel lens, so that the black edge of the screen is hidden under the Fresnel lens, but the method has a sawtooth structure which is not beneficial to the screen display in appearance.

In view of the above, after a great deal of research, the inventor proposes an optical fiber panel, which includes a plurality of optical fibers, wherein the plurality of optical fibers are arranged to form an incident portion, an intermediate portion and an exit portion, image light emitted from a display screen can be guided from the incident portion to the exit portion through the optical fiber panel, and the exit portion protrudes out of an orthographic projection range of the incident portion, so that a black edge of the display screen can be hidden under the exit portion, a screen ratio is improved, and a narrow-frame or completely frameless effect is achieved; meanwhile, the light propagation directions of the plurality of incident sections in the incident part and the plurality of emergent sections in the emergent part are the same, so that the propagation direction of the image light emitted by the display screen can not be changed, and the display effect is prevented from being influenced. Further, the inventor also provides a screen and an electronic device comprising the optical fiber panel.

Compared with the narrow frame scheme of the curved surface screen, the cost of the optical fiber panel is relatively low, and the edge display picture cannot be deformed. Compared with a Fresnel lens scheme, the optical fiber panel has no sawtooth structure in appearance and is more suitable for screen display. Second, the fiber optic faceplate is free of various aberrations due to refraction or diffraction. In addition, the optical fiber panel made of glass can be chemically strengthened to improve the strength, thereby replacing a common glass cover plate. The Fresnel lens made of glass is extremely difficult to process, so that the Fresnel lens is usually made of plastic, and the naturally-existing sawtooth structure on the surface of the Fresnel lens can greatly reduce the strength of the panel. In summary, the optical fiber panel has significant advantages in terms of appearance, display, material strength, and processing difficulty.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 and fig. 2 together, an embodiment of the present application provides an optical fiber panel 100, which includes a plurality of optical fibers 110, each optical fiber 110 includes an incident section 111, an intermediate section 112, and an emergent section 113 sequentially arranged along a light propagation direction, the incident sections 111 of the optical fibers 110 are connected to each other to form an incident portion 120, the intermediate sections 112 of the optical fibers 110 are connected to each other to form an intermediate portion 130, the emergent sections 113 of the optical fibers 110 are connected to each other to form an emergent portion 140, the emergent portion 140 at least partially protrudes out of an orthographic projection range of the incident portion 120, that is, a projection of the emergent portion 140 along a thickness direction completely covers a projection of the incident portion 120 along the thickness direction,

the light propagation directions of each exit segment 113 and each incident segment 111 are the same. In one embodiment, the light propagation directions of the plurality of incident segments 111 in the incident portion 120 and the plurality of exit segments 113 in the exit portion 140 are identical to each other, i.e., the light propagation directions of all the incident segments 111 and the light propagation directions of all the exit segments 113 are identical to each other. The orthographic projection direction of the incident portion 120 is the same as the light propagation direction of the exit segment 113 and the incident segment 111.

The optical fiber 110 guides light by total reflection of light, and the light propagation direction of the optical fiber 110 may refer to the axial direction of the optical fiber 110. All the emergent segments 113 and the incident segments 111 have the same light propagation direction, that is, all the emergent segments 113 and the incident segments 111 have the same axial direction.

Referring to fig. 3, the optical fiber panel 100 is configured to be mounted on a display screen 210, and the display screen 210 may include a display area 211 and a non-display area 212 (i.e., a black border) surrounding the display area 211. The incident portion 120 of the optical fiber panel 100 faces the display area 211 of the display panel 210, and the image light emitted from the display panel 210 is guided from the incident portion 120 to the intermediate portion 130 and then emitted through the emitting portion 140, so as to form an image display; since the emergent part 140 protrudes out of the incident part 120, the black edge of the display screen 210 can be hidden under the emergent part 140 (see fig. 7 in detail), the screen occupation ratio is improved, and the effect of narrow frame or no frame is realized; meanwhile, the light propagation directions of the plurality of incident sections 111 in the incident portion 120 and the plurality of exit sections 113 in the exit portion 140 are the same, so that the propagation direction of the image light exiting from the display screen 210 is not changed, and the display effect is not affected.

In this embodiment, the optical fiber 110 may be made of a transparent glass material, a transparent ceramic material, a transparent single crystal material, a transparent plastic material, or a composite material of two or more of the above materials.

Referring to fig. 1 and 4, the optical fiber 110 may include a core 115 and a cladding 116 covering the core 115, and light is transmitted through the core 115. In the process of manufacturing the optical fiber panel 100, a large number of optical fibers 110 may be arranged in an array to form an optical fiber panel preform, and after the optical fiber panel preform is softened at a high temperature, the fiber core 115 and the cladding 116 are reduced in equal proportion under the action of gravity or external force, so that the diameters of the optical fibers 110 are reduced, and the incident portion 120, the intermediate portion 130, and the exit portion 140 with different widths are formed.

The number of the optical fibers 110 may be determined according to the size and pixel size of the display screen 210, and the optical fiber panel 100 may cover the display area 211 and at least a portion of the non-display area 212 of the display screen 210.

As an embodiment, as shown in fig. 4, the number of the optical fibers 110 is the same as the number of the pixels 213 of the display screen 210, and the incident segment 111 of each optical fiber 110 is disposed corresponding to one pixel 213 of the display screen 210, so as to ensure that the resolution of the optical fiber panel 100 is not lower than the resolution of the display screen 210. Or, as shown in fig. 5, a plurality of adjacent pixels 213 may correspond to one optical fiber 110, that is, the optical fibers 110 sent by the plurality of pixels 213 are simultaneously led out through one optical fiber 110, so that the number of optical fibers 110 may be reduced, and the cost is saved. Or, referring to fig. 6, each pixel point 213 of the display screen 210 may also correspond to multiple optical fibers 110, that is, light emitted by one pixel point 213 is guided out through the multiple adjacent optical fibers 110, and at this time, the resolution of the optical fiber panel 100 is greater than that of the display screen 210, so that a better display effect can be achieved.

Still referring to fig. 1 and 3, the incident portion 120, the intermediate portion 130, and the emergent portion 140 are sequentially stacked and arranged along the thickness direction of the optical fiber panel 100, and the light propagation direction of each emergent segment 113 and each incident segment 111 is the same as the thickness direction of the optical fiber panel 100, that is, both the emergent segment 113 and the incident segment 111 extend along the thickness direction of the optical fiber panel 100.

When the optical fiber panel 100 and the display screen 210 are assembled, the optical fiber panel 100 is stacked on the display screen 210, and the thickness direction of the optical fiber panel 100 is identical to the thickness direction of the display screen 210. The image light of the display screen 210 exits along the thickness direction of the display screen 210 and enters the incident section 111, and since the light propagation directions of the exit section 113 and the incident section 111 are the same as the thickness direction of the optical fiber panel 100, the image light can be ensured to exit from the exit section 113 along the thickness direction of the display screen 210 without changing the propagation direction of the image light.

The thicknesses of the incident portion 120, the intermediate portion 130, and the exit portion 140 may be determined according to actual requirements. As an example, the thickness of the incident portion 120 is smaller than that of the emission portion 140, the thickness of the emission portion 140 is smaller than that of the intermediate portion 130, and the area of the intermediate portion 130 gradually increases from the incident portion 120 toward the emission portion 140. Therefore, the thicknesses of the incident part 120, the intermediate part 130 and the exit part 140 can be reasonably distributed, a sufficient connection area between the exit sections 113 positioned on the outer layer is ensured, and the strength of the exit part 140 is improved. The thickness of the middle portion 130 is the largest, and the area of the middle portion 130 gradually increases from the incident portion 120 to the exit portion 140, so that a good transition effect can be achieved, and the occurrence of local stress concentration due to sudden size change of the optical fiber panel 100 can be avoided.

The specific shapes of the incident portion 120, the intermediate portion 130, and the exit portion 140 are determined according to the shape of the display screen 210, and the shapes of the incident portion 120, the intermediate portion 130, and the exit portion 140 are adapted to the display screen 210. As an example, the display area 211 of the display screen 210 is substantially rectangular, and the non-display area 212 is substantially rectangular frame-shaped. In this case, the incident portion 120 and the emission portion 140 may have a rectangular plate-like structure, and the intermediate portion 130 may have a rectangular table structure. The surface of the incident portion 120 facing away from the exit portion 140 is an incident surface 121, and the shape and size of the incident surface 121 are both consistent with those of the display area 211, so that the display content of the display area 211 is completely guided out. The surface of the exit part 140 departing from the incident part 120 is an exit surface 141, the entire exit surface 141 is a display area of the fiber optic panel 100, and the exit part 140 protrudes out of the incident part 120, that is, the exit surface 141 protrudes out of the incident surface 121.

The outer periphery of the exit part 140 at least partially protrudes outside the orthographic projection range of the entrance part 120. For example, the exit part 140 may protrude out of the entrance part 120 in one or both of the length direction and the width direction of the fiber optic panel 100. The length direction of the optical fiber panel 100 is the same as the length direction of the display screen 210, and the width direction of the optical fiber panel 100 is the same as the width direction of the display screen 210. For example, one side of the exit part 140 protrudes out of the entrance part 120 along the width direction of the fiber optic panel 100 to hide the non-display region 212 of one side of the display screen 210 in the width direction under the exit part 140; alternatively, both opposite sides of the exit part 140 protrude from the incident part 120 along the width direction of the fiber optic panel 100, so as to hide the non-display regions 212 on both sides of the display screen 210 in the width direction under the exit part 140; alternatively, the outer peripheries of the emitting portions 140 all protrude out of the incident portion 120, that is, the emitting portions 140 protrude out of the incident portion 120 along the length direction and the width direction of the fiber optic panel 100, so as to hide the entire non-display region 212 below the emitting portions 140.

The width of the exit part 140 protruding from the entrance part 120 may be determined according to the width of the non-display area 212. For example, the width of the exit part 140 protruding out of the entrance part 120 is smaller than the width of the non-display area 212, so as to shield part of the non-display area 212, thereby achieving a narrow-frame display effect. Alternatively, the width of the exit part 140 protruding out of the entrance part 120 is greater than or equal to the width of the non-display area 212, so as to shield the whole non-display area 212, thereby achieving a real frameless display effect.

The incident surface 121 and the exit surface 141 of the optical fiber panel 100 may be flat surfaces or curved surfaces having arbitrary shapes. When the incident surface 121 is a plane, the incident surface 121 may be attached to the display screen 210, so as to facilitate assembly between the optical fiber panel 100 and the display screen 210 and improve assembly stability of the optical fiber panel 100 and the display screen 210. When the incident surface 121 is a curved surface, a certain gap may exist between the incident surface 121 and the display screen 210, but as long as the light propagation direction of the incident section 111 is consistent with the thickness direction of the display screen 210, the direction of the image light emitted by the display screen 210 is not changed.

In other embodiments, the longitudinal section of the display screen 210 may also be a circle, a triangle, a trapezoid, a sector, a semicircle or other irregular shapes, and the longitudinal sections of the incident portion 120 and the exit portion 140 may be adjusted to corresponding shapes, which is not described herein. The longitudinal section of the display screen 210 is perpendicular to the thickness direction of the display screen 210, and the longitudinal sections of the incident part 120 and the exit part 140 are perpendicular to the thickness direction of the optical fiber panel 100.

In some embodiments, a surface of the exit part 140 facing away from the incident part 120 is formed with a compressive stress layer (not shown in the figures). The compressive stress layer can improve the strength of the optical fiber panel 100, and the compressive stress layer can replace a glass cover plate, so that the structure of the optical fiber panel 100 is simpler.

In the present embodiment, the optical fiber panel 100 may be formed with a compressive stress layer by reinforcement, including but not limited to physical reinforcement, chemical ion exchange reinforcement, ion implantation reinforcement, and the like. In addition, the strength of the plastic material in the optical fiber panel 100 can be improved by a treatment method such as UV curing or thermal curing, thereby further improving the strength of the optical fiber panel 100.

In some embodiments, the fiber optic faceplate 100 may further include an optical coating (not shown), which is stacked on a surface of the exit section 140 facing away from the incident section 120, i.e., stacked on the exit surface 141. The optical coating may be an antireflection coating to increase the optical transmittance of the optical fiber panel 100; the optical coating film may also be a wear-resistant film to improve the surface wear resistance of the optical fiber panel 100; the optical coating film can also be an anti-fingerprint film so as to realize the anti-fingerprint effect of the surface of the panel; alternatively, the optical coating may have two or more functional properties, for example, the optical coating may be a wear-resistant antireflection film, or an antireflection film having wear-resistant and anti-fingerprint properties.

In this embodiment, the material of the optical coating may include one or more of silicon oxide, tantalum oxide, titanium oxide, silicon carbide, polytetrafluoroethylene, and other organic fluorides, and may be determined according to the functional characteristics of the optical coating, and is not limited in detail here.

In some embodiments, the optical fiber panel 100 may further include a transparent conductive film (not shown), the transparent conductive film is both conductive and has high transmittance in a visible light range, and the transparent conductive film is stacked on a surface of the exit part 140 facing away from the incident part 120, so that the optical fiber panel 100 has a touch function.

In the present embodiment, the transparent conductive film includes, but is not limited to, ITO (tin-doped indium trioxide), AZO (aluminum-doped zinc oxide), and the like. The method for disposing the transparent conductive film on the surface of the optical fiber panel 100 may be coating, printing, evaporation, sputtering, deposition, and the like, and may be determined according to actual requirements. It is noted that in some embodiments, the optical fiber panel 100 includes both an optical coating and a transparent conductive film, and the transparent conductive film may be stacked between the optical coating and the exit part 140 to protect the transparent conductive film through the optical coating.

Still referring to fig. 1 and 2, in some embodiments, the relative position of the incident section 111 of the optical fiber 110 at the incident portion 120 corresponds to the relative position of the emergent section 113 of the optical fiber 110 at the emergent portion 140. For example, the incident section 111 of the same optical fiber 110 is second in the first row of the incident portion 120, and the emergent section 113 is also second in the first row of the emergent portion 140. In one embodiment, the incident portion 120 and the exit portion 140 have the same cross-sectional shape, and the ratio of the cross-sectional size of the exit portion 140 to the cross-sectional size of the incident portion 120 is a value λ greater than 1; for example, the cross-sectional shapes of the incident portion 120 and the exit portion 140 are both rectangular, and the ratio of the cross-sectional perimeter of the exit portion 140 to the cross-sectional perimeter of the incident portion 120 is a value λ greater than 1; the incident section 111 and the exit section 113 of each optical fiber 110 are parallel to each other, and a plane formed by the incident section 111 and the exit section 113 passes through a central axis of the optical fiber panel 100, that is, the central axis of the optical fiber panel 100 is located on the plane formed by the incident section 111 and the exit section 113;

the entrance segment 111 and the exit segment 113 are located on the same side of the central axis in this plane, and the ratio of the distance between the exit segment 113 and the central axis to the distance between the entrance segment 113 and the central axis is also λ. Thus, it is ensured that the pattern displayed by the fiber optic panel 100 is consistent with the pattern displayed by the display screen 210 or is the result of the equal-scale amplification.

Referring to fig. 7, in some embodiments, the relative position of the incident section 111 of the optical fiber 110 at the incident portion 120 is different from the relative position of the emergent section 113 of the optical fiber 110 at the emergent portion 140. For example, the same optical fiber 110 has the incident section 111 second from the left of the first row of the incident portion 120 and the emergent section 113 second from the right of the penultimate row of the emergent portion 140, so that the pattern displayed on the display screen 210 can be changed. In one embodiment, the cross-sectional shapes of the incident portion 120 and the exit portion 140 are identical, and the ratio of the cross-sectional size of the exit portion 140 to the cross-sectional size of the incident portion 120 is a value λ greater than 1; the incident section 111 and the exit section 113 of each optical fiber 110 are parallel to each other, and a plane formed by the incident section 111 and the exit section 113 passes through a central axis of the optical fiber panel 100, that is, the central axis of the optical fiber panel 100 is located on the plane formed by the incident section 111 and the exit section 113; the entrance section 111 and the exit section 113 are located on opposite sides of the central axis in the plane, and the ratio of the distance between the exit section 113 and the central axis to the distance between the entrance section 113 and the central axis is also λ. Therefore, the image displayed by the optical fiber panel 100 can be symmetrical to the image displayed by the display screen 210 as a center, so that the display content of the display screen 210 can be displayed in a turning manner, and different requirements of users can be met.

In this embodiment, the cross-section of the intermediate portion 130 is generally hourglass-shaped, and the intermediate sections 112 of the intermediate portion 130 are staggered with respect to one another, which may improve the strength of the connection between the intermediate sections 112.

Referring to fig. 8, an embodiment of the present application further provides a screen 200, which includes a display screen 210 and an optical fiber panel 100, wherein the optical fiber panel 100 is stacked on the display screen 210, the display screen 210 includes a display area 211 and a non-display area 212, the incident portion 120 of the optical fiber panel 100 covers the display area 211, and the emergent portion 140 at least partially covers the non-display area 212.
