Abstract

An optical fiber display with capability of displaying multi-image comprises a transparent panel and a plurality of fiber units inside an outer frame. The fiber units are interleavedly arranged on the inner side of the transparent,and towards to different directions respectively. Thus, when the different images are projected by different fiber units, the different images can be observed from different view angles, and the effect to display multi-image can be achieved. Beacause of the interleaving of the fiber units, the multi-image is smooth and the switch has no interval.

Description

Fiber optic display capable of displaying multiple screens

The present invention relates to a fiber optic display, and more particularly to a fiber optic display that can display multiple frames. ' Background technique

In the early years, in order to use the focus of the public to strengthen the billboards for large-scale advertisements, the use of display technology is not yet mature. It can only be cut into multiple small screens and then stacked by multiple TV sets. Large TV walls are broadcast separately.

However, since a plurality of television sets are stacked, the frame of the television cannot be obscured, so that the entire screen is cut into a plurality of small squares by the frame, so that the viewer can not see the complete picture, and the original intention of the operator is greatly discounted.

• Later, there were displays on the market that were made of light-emitting diodes (LEDs below). Since they were arranged in a stack, they did not have a frame like the TV, and the LED display has been developed to date. The clarity is also much better than that of a TV set. However, since LEDs are still high-priced electronic components, billboards for making a large advertisement often require tens of thousands of LE.D, so if the cost is high, but the corresponding effect is obtained, the operator is often troubled.

In order to solve the above problems, it is common to use fiber optic displays instead of LED displays to make large billboards. The fiber optic display provides an image by a projector, transmits the image through the optical fiber, and is arranged on the inner side of a flat transparent panel at the other end of the optical fiber, thereby forming a large-area optical fiber display. The biggest difference between optical display and LED display is that the production cost of optical fiber is much lower than that of LED. Therefore, billboards or large-scale image billboards for making large advertisements with fiber-optic displays are the mainstream today.

Although the optical fiber display has the above advantages, the billboards of the current large advertisements can only play the image projected by one projector, that is, the billboard of a large advertisement can only play one image at a time, thus being crowded. In the city, there is bound to be a billboard for large advertisements because there is not enough space, and the effect that the billboards of large advertisements can achieve is greatly reduced. -

Summary of the invention

In order to solve the above problems, it is a primary object of the present invention to provide a fiber optic display which can simultaneously display images of a plurality of projectors.

Since the optical fiber groups of the present invention are respectively oriented in different directions, when the optical fibers of different optical fiber groups project images of different projectors, images projected by different projectors can be seen from different angles, thereby displaying multiple images. The effect, and because the fiber groups are staggered, the screen transitions naturally between the boundaries without gaps.
