Description

Fiber optic display capable of displaying multiple screens

technical field

The utility model relates to an optical fiber display, in particular to an optical fiber display capable of displaying multiple pictures.

Background technique

In the early years, in order to enhance the public's focus on large-scale advertising billboards, the industry used large-scale advertising billboards that can display moving images to replace monotonous large-scale advertising billboards; at that time, due to the limitation of display technology, it was not yet mature. , the screen can only be cut into multiple small screens, and then broadcast separately on a large TV wall formed by stacking multiple TVs.

However, after multiple TV sets are stacked, the frame of the TV set cannot be covered, so that the entire picture is cut into multiple small squares by the frame, which makes it inconvenient for the viewer to appreciate the complete picture, and greatly reduces the original intention of the industry.

Afterwards, displays made of light-emitting diodes (hereinafter referred to as LEDs) appeared on the market. After they were arranged and stacked, they did not have the trouble of borders like the above-mentioned TV sets. It is also much better than TV sets. However, because LEDs are still high-priced electronic components, tens of thousands of LEDs are often needed to make a large advertising billboard. Therefore, if the corresponding effect cannot be obtained at such a high cost, the industry is often troubled.

In order to solve the above problems, fiber optic displays are generally used in the market instead of LED displays to make large billboards. The optical fiber display uses a projector to provide images, transmits the images through the optical fiber, and arranges the other end of the optical fiber on the inner side of a plane transparent panel, thereby forming a large-area optical fiber display. The biggest difference between fiber optic displays and LED displays is that the production cost of fiber optics is much lower than that of LEDs, so making large advertising billboards or large image billboards with fiber optic displays has become the mainstream today.

Although the optical fiber display has the above-mentioned advantages, the current large-scale advertising billboards can only play the image projected by one projector, that is, a large-scale advertising billboard can only play one image at the same time. In urban cities, there will be no enough space to set up large-scale advertising billboards, and the effect that large-scale advertising billboards can achieve will be greatly reduced.
