5. Description of the invention (3) ^ The light transmitted from the plurality of light curtains connected to the light collecting device is converted into visible light. The purpose and many advantages of the present invention will be fully explained by detailed description and with reference to the attached drawings. [Exposure ...] [Detailed description of the invention] Some embodiments of the present invention will be described in detail as follows , Straight, different parts are not drawn according to actual size. Certain scales are related to other parts of the scale than exaggerated representations to provide a clearer description for those skilled in the art to understand the invention. Example: As shown in the second figure, the display condition is the day frame frequency (frame

frequency): 1/60 second, that is, the refresh period (refresh period) is 16.7 centiseconds (m sec); the resolution is XGA, which is 1 024 (x 3) χ 7 6 8 diurnal (pi X e 1 s). First, an external circuit 100 is used to control the on and off of the point-aligned light source 70. Among them, the line-shaped light source may be 3072 ultraviolet light emitting diodes (UV LEDs) and ultraviolet laser diodes ( UV Laser diode), blue laser diode and blue light emitting diode (LED), and then use one or more

124294 Γ —- ^ Day of the month, 5th, description of the invention (4) " '— * — 1 shooting rotating mirror' is here an octagonal mirror 80 (that is, one day frame is scanned every 1/8 revolution) ' However, it is also possible to use one of rotating plane mirror, rotating triangle, four corners ... to twentieth angle = face mirror; in addition, the total length of the rotating mirror 80 may be greater than, equal to, or shorter than the total length of the linearly arranged light sources 70, in This series is the same length; together with a motor 90 (speed (1/8) / 〇 · 〇ΐ67 rev / sec = factory 5 fev / sec = 450 rpm), the light emitted from the linear array light source 70 will be reflected. 2 Sweeping into a plane, and then collected by a light collecting device, this light collecting device is here, an arc-shaped sheet structure 60, the concave surface faces the octagonal mirror 80, the convex surface has a complex, fiber connection points, each Each point is provided with a fiber 50 connected to a fiber array screen 4 with a plurality of fiber connection points. Next, a plurality of optical fibers 50 connected to the light collecting device are used to transmit light to an optical fiber array screen 40. This optical fiber 50 is a 3D three-dimensional structure of the entire bundle, not only the upper and lower rows of the upper and lower rows), and then A screen 30 coated with a fluorescent layer is used to convert the light from the fiber array screen f into visible light, and a diffusion layer 20 is used to uniformly diffuse the light from the screen 30 coated with the i-side light layer. The present invention can achieve many improvements with the above-mentioned display method and device.

This is an advantage, because the optical fiber array is used to enlarge the flat display of the image. This will not cause the problem of distortion and curvature of the screen like the CRT or pr0ject0r of the magnifying shirt.

The method is that the light in the RT is not stretched in the cathode ray tube, the crystal medium ', or through the traveling system V of any direct or light in the LCD. The present invention uses optical fibers as light transmission. The medium is made of a transmissive liquid rather than a complex total reflection. Therefore, the display device of the invention can be greatly improved, and has two advantages of good uniform H-mesh poem af. Because the optical fiber itself has a very small diameter and has The excellent Koji and I ^ can therefore reduce the distance between the optical fiber display screen and the two sources in a straight line and the square mirror to a very short distance. The light devices can be designed to be very small and placed on the underside or outside of the display screen. Therefore, the thickness of the optical fiber display of the present invention can be greatly reduced compared to a projector and a CRT, and can be controlled below 100 mm.

The fourth advantage is that since the present invention uses optical fiber as a medium for light transmission (and amplification), there is no problem of low yield of LCD process in large-area panels. Therefore, it can be equal to PDP and projector, or even Larger display area, its display range is about 20 inch to 200 inch. The above are only preferred embodiments of the present invention, and are not intended to limit the scope of patent application for the present invention; all other equivalent changes or modifications made without departing from the spirit disclosed by the present invention should be included in the following applications Within the scope of the patent.
