Embodiment Construction

[0029] Figure 1-8 And 10-14 illustrate a preferred embodiment of the variable space shutter 10 according to the present invention. As shown in the figure, the variable space shutter according to the present invention is formed by a first frame 12, a second frame 14, and a shutter member 16 sandwiched between the first and second frames. figure 1 with 2 It is an exploded front and rear view. The first frame 12 includes a vertical slat 13a forming a vertical opening 13b and a plurality of mounting holes 38 with LEDs. The mounting holes are provided for mounting LEDs for displays that use variable space shutters.

[0030] A screw 18 (preferably a socket screw) is provided to keep the shutter member 16 in place and also allows horizontal movement within the horizontal oval hole 22. The screw 18 and the hole 22 together allow lateral movement while keeping the shutter between the frames 12 and 14 when the variable space shutter 10 is assembled. In a preferred embodiment, the screw ...

Abstract

A variable space shutter includes: a first frame having vertically spaced slats forming vertical openings; a second frame having a horizontal indented channel, the second frame being affixed to the first frame around a periphery of the first frame; and a shutter part having vertically spaced slats forming vertical openings, the shutter part being sandwiched between the first and second frames such that a portion of the shutter part rests within the horizontal indented channel to permit selective sliding movement of the shutter within the channel between a first position, wherein the vertical openings of the first frame line up with the vertical openings of the shutter part, to permit light to pass through the variable space shutter, and a second position, wherein the vertical openings of the first frame line up with the vertical slats of the shutter part, to block light from passing through the variable space shutter.

Description

[0001] Cross reference of related applications [0002] This PCT international application claims the priority of U.S. Provisional Patent Application No. 61 / 362,593 filed on July 8, 2010, and is hereby incorporated by reference. Background technique [0003] The application relates to a variable space shutter for LED displays. In a preferred embodiment, the shutter includes a portion that allows the shutter to change from a light transmitting (open) state to a light blocking (closed) state. [0004] Traditionally, the backing mesh of the LED display is used, for example, in the working state to provide a backing for the LED light display. Typically, a transparent screen that allows light to pass through or a solid-type screen that provides back contrast is provided. [0005] However, with conventional equipment, it is necessary to decide which of the transparent panel and the solid panel to use for a specific application. Summary of the invention [0006] In view of the above-mention...
