Embodiment 1

[0036] Such as figure 1 , figure 2 , image 3 , Figure 5 , Figure 6 As shown, a high-quality large-screen display with seamless splicing of arbitrary curved planes is composed of a plurality of brick-shaped optical fiber rear-projection display modules. , a signal processing module 2, a liquid crystal display panel 3, an LED light source module 4, a fixing device and a housing 5, an anti-glare frosted coating 6, a touch sensor panel 7, and the variable cross-section optical fiber panel 1 is located outside the optical fiber rear projection display module The variable cross-section fiber optic panel 1 projects the content of the liquid crystal display panel 3 onto the surface of the optical fiber rear projection display module through optical fiber transmission, and the liquid crystal display panel 3 is located at the rear end of the variable cross section fiber optic panel 1, and transmits signals from The video signal of the processing module 2 is displayed in the transl...

Embodiment 2

[0053] Such as Figure 4 As shown, when it is necessary to produce a curved surface display large screen, the multiple high-transmittance variable-section optical fibers 11 are clustered and arranged through a mold, poured into a light-weight filling material 12 and solidified into a roughly curved shape, and then the inner and outer cross-sections are cut. Cutting, so that the cutting surface of the outer section of the optical fiber is as vertical as possible to the optical fiber, reducing the difference in the shape and area of ​​the outer section of each optical fiber after cutting, and then moderately grinding and polishing the surfaces on both sides of the variable-section optical fiber panel 1; The optical fiber rear projection display module can be stacked into a display screen with any curved surface, any special shape, and any area such as plane, arc, cylinder, and sphere.

Abstract

The invention discloses an arbitrary-curved-surface plane seamless spliced high-quality large-screen display device. The arbitrary-curved-surface plane seamless spliced high-quality large-screen display device is formed by stacking brick-shaped optical-fiber rear-projection display modules, wherein elements of each brick-shaped optical-fiber rear-projection display module include a variable-cross-section optical fiber panel, a signal processing module, a liquid crystal display panel, an LED (light-emitting diode) light source module, a fixing device, a shell, an anti-dazzling frosting coating and a touch sensing plate. The arbitrary-curved-surface plane seamless spliced high-quality large-screen display device has beneficial effects that a seamless spliced high-quality screen with small dot pitch can be produced, a display video picture of an arbitrary curved surface, a special arbitrary shape, and an arbitrary area can be realized; the seamless splicing principle is the primary-pixel splicing principle, pixel points are uniformly and compactly arranged, and the display consistency of the brightness and color is optimal; by adopting the modularized production, the constitutional part is easy to repair and replace; the touch sensing plate can be embedded into the display device, so that precision in positioning can be realized, and the picture quality and the shape of the display device are not affected; the water resistance and collision resistance are relatively good.

Description

【Technical field】 [0001] The invention relates to a high-quality large-screen display, in particular to a high-quality large-screen display with arbitrary curved surface and plane seamless splicing. 【Background technique】 [0002] Large-screen displays are an important part of modern video display screens, mostly made of LED screens, rear projection screens, LCD flat-panel TVs, and plasma flat-panel TVs. Traditional LED screens have the disadvantages of large dot pitch, narrow color gamut, and poor display quality, which are not suitable for displaying high-quality content indoors; excessive light decay will occur after long-term use, requiring overall replacement, and the cost is relatively high. ; Traditional rear-projection screens, LCD flat-panel TVs, plasma flat-panel TVs, etc. have the disadvantages of being unable to achieve seamless splicing and arbitrary curved surface display, poor waterproof and impact resistance, and cannot be used in outdoor occasions, and the m...
