Description

Technical Field

[0001] The present invention relates to the technical field of holographic screens, and in particular to a lamp-driven integrated holographic screen. Background Art

[0002] A holographic display screen is a display screen in which lamp beads are installed on a keel frame. A number of through holes are opened on the surface of the keel frame to achieve a high light transmittance effect. The lamp beads are distributed around the through holes as pixel points to provide a display image. The lamp-driver is integrated, that is, the LED lamp beads and driver chip IC, as well as other components are all encapsulated in the LED lamp beads, so that other components cannot be seen from the periphery. The back is smooth and flat, thus achieving a display screen with better transparency.

[0003] Existing holographic screens mainly achieve the purpose of holographic display by achieving light transmission effect through the existence of through holes, but such a structure has a major pain point. The larger the size of the through hole, the better the light transmittance, but the spacing between the lamp beads will be widened, resulting in a lower resolution of the holographic display. When the display screen is viewed from a close distance, there is a strong sense of separation. Conversely, increasing the resolution will cause the spacing between the lamp beads to decrease, and the size of the through hole will become smaller, thereby reducing the light transmittance. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a holographic screen integrating lamp and driver to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lamp-driven integrated holographic screen, comprising a control circuit board and a mounting frame, a reflective film is arranged on the back of the mounting frame, optical fibers penetrate through both sides of the mounting frame, light-blocking frames are connected to the top and bottom of the mounting frame, and a support bar is connected to the back of the light-blocking frame.

[0006] By adopting the above technical scheme, part of the light emitted by the LED lamp beads is reflected into the interior of the optical fiber through an obliquely arranged reflective film, and the optical fiber is a side-light optical fiber, which can not only transmit light inside but also emit light from the side wall to the outside, filling the space between the LED lamp beads, making the gap between the display pixels smaller, thereby reducing the sense of picture fragmentation and improving the display effect. The optical fiber is prevented from emitting light in all directions by the setting of a light-blocking frame, and the direction of the light emitted by the optical fiber is limited to correspond to the direction of the light emitted by the LED lamp beads. At the same time, the support bar is arranged to facilitate the support of the light-blocking frame through the keel frame, thereby avoiding bending due to excessive span of the light-blocking frame.

[0007] Furthermore, the optical fiber is a side-lighting optical fiber.

[0008] By adopting the above technical solution, the optical fiber is a side-light optical fiber, which can not only transmit light inside but also emit light from the side wall to the outside, filling the space between the LED lamp beads.

[0009] Furthermore, the reflective film is arranged at an angle.

[0010] By adopting the above technical solution, part of the light emitted by the LED lamp bead is reflected into the optical fiber through the inclined reflective film.

[0011] Furthermore, the optical fibers, light shielding frames and support bars are each provided in four groups, and the four groups of optical fibers, light shielding frames and support bars are distributed in a ring array.

[0012] By adopting the above technical solution and setting four groups of optical fibers, the gaps between multiple LED lamp beads can be filled to reduce the sense of fragmentation.

[0013] Furthermore, the light blocking frame and the supporting strips are both made of polyurethane material.

[0014] By adopting the above technical solution, since the light blocking frame and the support bars are both made of polyurethane material, the light blocking frame and the support bars can deform along with the deformation of the keel frame, thereby preventing the light blocking frame and the support bars from affecting the deformation of the keel frame.

[0015] Furthermore, a keel frame is connected to the top of the control circuit board, and through holes and a lamp drive housing are respectively provided on the outer surface of the keel frame.

[0016] By adopting the above technical solution, the lamp driver housing is supported by the keel frame, and the control circuit board is connected to the external current and electrical signals to make the LED lamp beads and the driver IC operate.

[0017] Furthermore, a plurality of through holes are provided, and the plurality of through holes are distributed in a rectangular array.

[0018] By adopting the above technical solution, the light transmittance of the holographic screen is improved by setting a plurality of through holes, and the heat dissipation area of ​​the holographic screen is increased.

[0019] Furthermore, the lamp driver housing has driver IC and LED lamp beads installed inside, respectively, and the mounting frame is connected to the four sides and the outer surface of the lamp driver housing.

[0020] By adopting the above technical solution, the driver IC and LED lamp beads are concentrated inside the lamp driver housing, achieving the purpose of lamp driver integration, thereby reducing the setting of copper busbars.

[0021] Furthermore, the driver IC and LED lamp beads are provided in plurality, and the plurality of driver ICs and LED lamp beads are distributed in a rectangular array.

[0022] By adopting the above technical solution, each LED lamp bead is a pixel point, and the pixel points formed by multiple LED lamp beads cooperate to form an image.

[0023] Furthermore, the support bar is fixedly connected to the keel frame by means of adhesion through an adhesive, and the mounting frame is fixedly connected to the lamp drive housing by means of adhesion through an adhesive.

[0024] By adopting the above technical solution, the mounting frame and the supporting bar can be fixed on the surface of the keel frame and the lamp drive housing only by applying a flexible adhesive on the surface of the keel frame.

[0025] In summary, the present invention mainly has the following beneficial effects:

[0026] 1. The present invention, through the arrangement of the reflective film and the optical fiber, reflects part of the light emitted by the LED lamp beads into the inside of the optical fiber through the inclined reflective film, and the optical fiber is a side-light optical fiber, which can not only transmit light inside but also emit light from the side wall to the outside, fill the space between the LED lamp beads, make the gap between the display pixels smaller, thereby reducing the sense of fragmentation of the picture and improving the display effect; reduce the sense of fragmentation of the picture when watching from close up and improve the display effect;

[0027] 2. The present invention prevents the optical fiber from emitting light in all directions by setting a light-blocking frame, and limits the direction in which the optical fiber emits light to correspond to the direction in which the LED lamp beads emit light, thereby preventing the disordered light from affecting the display of fresh fruits;

[0028] 3. The present invention arranges support bars, which facilitates supporting the light shielding frame through the keel frame, thereby preventing the light shielding frame from bending due to excessive span, and improving the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS
