Description

A kind of variable curvature cylinder runner plate

Technical field

The utility model relates to a kind of variable curvature cylinder runner plate being applicable to indoor bore hole two viewpoint stereotelevision.

Background technology

Existing bore hole tridimensional electronic giant-screen generally adopts multiple views structure, is all generally call oneself stereotelevision or claim 3D TV, but is strictly all two viewpoints according to 3D radio and television and the definition of three-dimensional film program, therefore it can not be called " TV ".Its key distinction is, multiple views display increases visual angle, but in calculating in resolution, viewpoint number is in denominator position, also namely viewpoint number is more, resolution is lower, and multiple views display all cannot be watched for the 3D radio and television of two viewpoints and three-dimensional film program, cannot realize the bore hole display of stereotelevision.And the stereo display visual angle of common two viewpoints is too little, this is one of the major reason that cannot implement of bore hole type LED stereotelevision for a long time.

Utility model content

Traditional cylinder runner plate waits radius, according to optical correlation computing formula: sin i/ sin γ=n, represents that incident angle sine is directly proportional with refraction angle sine, and when incident angle increases, refraction angle is accelerated to increase, and no longer reflects to during certain angle, defines the reduction of real visual angle.

The purpose of this utility model is the less problem in the stereo display visual angle in order to solve two viewpoints, by increasing incident angle, namely increases the radius-of-curvature of cylinder runner plate, and then increases visible angle.

The technical solution used in the present invention is: a kind of variable curvature cylinder runner plate, and the radius-of-curvature of described variable curvature cylinder surfaces of mirror plate increases from centre normal gradually to both sides radius.

Further, described variable curvature cylinder runner plate is bonded in LED illuminating module, and multiple LED illuminating module composition luminescence units or luminous casing, form display screen further.

Further, described variable curvature cylinder runner plate can also be arranged on the integral display that is made up of multiple common illuminating module.

The beneficial effect that the utility model produces is: by the radius-of-curvature of accurate Calculation cylinder surfaces of mirror plate, when light is externally propagated from cylindrical mirror intralamellar part, through the proportional increase of medium refraction angle, when display angle changes, further increase the visible angle of display.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by structure specifically noted in instructions below or accompanying drawing and be obtained.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

The utility model is a kind of variable curvature cylinder runner plate, the medium of this cylindrieal lens plate is epoxy resin, sub-Gree or other engineering plastics, its refraction coefficient is 1.4-1.55, for value 1.47, traditional single radius-of-curvature cylindrical mirror, when light resin/Air Interface incident angle is 10 degree, 20 degree, 30 degree, when 40 degree, emergence angle is respectively as calculated: 14.8 degree, 30.2 degree, 47.3 degree, 70.9 degree, therefore, along with the increase of incident angle, refraction angle is accelerated to increase, and when reaching 42.8 degree to incident angle, light is totally reflected, and no longer reflect, define the reduction of real visual angle.

The utility model designs according to curvature radius cylindrical mirror version, when variable curvature cylinder surfaces of mirror plate leaves centre normal, radius progressively increases, the cylinder runner plate on the surface radius-of-curvature of every bit can calculate according to the friendship enlargement ratio of refractive index and angle of incidence of light and setting and accurately obtain, then obtains curvature radius cylinder by multi-point fitting mode.Like this, when incident angle increases, the radius-of-curvature of cylinder surfaces of mirror plate is along with increase, like this along with the object increased makes when incident angle increases, refraction angle is not accelerated to increase, but proportional increase, like this when display angle changes, refraction angle is directly proportional to the visual angle of display or close to direct ratio, instead of the sine at refraction angle is directly proportional to display viewing angles or close to direct ratio, which increases visible angle.

Shown in Fig. 1 is a kind of variable curvature cylinder runner plate 1, and cylinder runner plate goes out the cross sectional shape of this variable curvature cylinder runner plate by formulae discovery, and wherein dotted line represents traditional cambered surface such as radius such as grade, and solid line is the variable curvature cambered surface in the utility model.Cylinder runner plate 1 rear is provided with luminescence chip 2, after each colonnade of the utility model central column face runner plate 1, is provided with two groups of luminescence chips 2.The actual variable curvature cylinder runner plate made as shown in Figure 2.

In the design of curvature radius cylindrical mirror, according to light refractive index in media as well and angle of incidence of light, according to isogonism enlargement ratio principle, calculate the radius-of-curvature of diverse location on interface, then obtain the aspheric surface equation of curvature radius cylinder by multi-point fitting mode.

As shown in Figure 3 and Figure 4, L represents left eye pixel, and R represents right-eye pixel, and RGB represents RGB respectively.The utility model can be applied in LED stereotelevision: be bonded in Pork-pieces LED illuminating module by the cylindrieal lens plate according to mentioned above principle manufacture, re-uses multiple LED illuminating module and is assembled into luminescence unit or luminous casing further; Also multiple common illuminating module first can be used first to be assembled into integral display, then to produce the cylindrieal lens plate integral installation of bulk on display according to total size.

As shown in Figure 5, when needing the display pixel increasing LED panel, display mode line by line can be adopted; As shown in Figure 6, when row display mode is taken out in employing, under the condition slightly reducing display pixel, manufacturing cost can be effectively reduced.

Above embodiment 1 makes manufacture become easy, and cost lowers, but between module, gap needs proper process; The appearance of embodiment 2 is better, but the manufacture difficulty of bulk cylindrieal lens plate is larger.
