Abstract
The preparation method for optical fiber screen with composite yarn relates to drawing and application of optical fiber. Compared with existing technique that manufactures optical screen with low resolution used by single optical fiber, this method prepares composite yarn firstly with multiple single fibers of diameter as microns, then manufactures the fiber screen with composite yarn to increase resolution greatly. This invention can be used in ultrathin high-resolution screen.
Description
Technical field:
The present invention relates to the drawing and the application of optical fiber, finally produce optical fibre screen, belong to optics display unit manufacture technology field.
Background technology:
In relevant known technology, the Chinese patent application that application number is 200310105408, name is called a kind of back projection optical fibers screen device and preparation method thereof discloses a kind of optical fibre screen production program.This scheme is that optical fiber is arranged in parallel into the optical fiber cylinder, sees shown in Figure 1ly, and plastic optical fiber is softening under 600～1400 ℃ of temperature at 70～90 ℃, glass optical fiber, tightly compacted, the optical fiber cross section becomes the self-adaptation shape by circle, and all optical fiber do not have the gap contact, become one.At this moment optical fiber cylinder is obtained the optical fibre screen hair plates along the section of optical fiber axial direction due, hair plates both ends of the surface and periphery are carried out promptly making optical fibre screen after the optics processing.The method that also has a kind of drawing optical fiber multifilament in the prior art, in the process of making optical fiber image transmission beam, use, just a kind of secondary fiber elongation method, be about to long number sections such as simple optical fiber is cut into, tie into a branch of, wire drawing once more, the fibre bundle that is drawn is said multifilament, its diameter can be seen shown in Figure 2 below 1mm.Such optical fiber includes several thinner optical fiber 1.
Summary of the invention:
The main deficiency that optical fibre screen in the known technology exists is that resolving power is low, and limiting resolution is less than 2LP/mm, and this is because employed fibre diameter is bigger, is generally 0.3mm.If use thinner optical fiber, operate the very difficulty that becomes, be difficult to these optical fiber are arranged in parallel, cause this method almost can't realize.And multifilament diameters of the prior art also can reach the simple optical fiber diameters.So in order to improve the resolving power of optical fibre screen, we have invented the method for the present invention's employing multifilament making optical fibre screen.
The present invention realizes like this, every optical fiber multifilament 2 is arranged in parallel, and tightly packed is multilayer, forming the cross section is orthogonal optical fiber cylinder, see shown in Figure 3ly, be heated to the softening temperature of fiber optic materials again, multifilament 2 cross sections become the self-adaptation shape by circle, all multifilament do not have the gap contact, become one.Produce optical fibre screen by known technology again.
Because multifilament 2 diameters that adopted can be identical with simple optical fiber 1 diameter, with its alternative simple optical fiber 1, and a multifilament 2 contains thousands of single thinner optical fiber 1, as 5 μ m, so its resolving power of optical fibre screen of making according to the present invention's method greatly improves, because of including the diameter difference of simple optical fiber 1, limiting resolution can reach 65～100LP/mm, thereby has overcome the deficiency of known technology fully.
Description of drawings:
Fig. 1 is a known technology with the optical fiber formed optical fiber cylinder schematic perspective view that is arranged in parallel.Fig. 2 is a multifilament schematic cross-section of the prior art.Fig. 3 is that the present invention's making method is arranged in parallel every optical fiber multifilament, and tightly packed be multilayer, forming the cross section is orthogonal optical fiber cylinder body section synoptic diagram.
Embodiment:
See Fig. 2, shown in Figure 3, with long number sections such as single glass material optical fiber 1 are cut into, tie into a branch of, wire drawing once more, the fibre bundle that is drawn is required multifilament 2, its diameter can be below 1mm, as 0.2～0.5mm, length is tens millimeters, as 30mm, the diameter of simple optical fiber 1 wherein generally is about 5 μ m in 4～6 mu m ranges.In a cross section is in the orthogonal mould, every optical fiber multifilament 2 is arranged in parallel, and tightly packed be multilayer, forming the cross section is orthogonal optical fiber cylinder, rectangular dimension is 100 * 100mm
2, see shown in Figure 3.Put into process furnace through preheating together with mould, heat up, outlet temperature is controlled between 550～600 ℃, is incubated 30 minutes, is cooled to room temperature by the speed of 1 ℃/min.In this course, multifilament 2 cross sections become the self-adaptation shape by circle, and all multifilament 2 no gap contacts are bonded as one.At this moment optical fiber cylinder is obtained the optical fibre screen hair plates along the section of optical fiber axial direction due, can determine the thickness of hair plates as required.The hair plates two ends are reached periphery and carry out precise optical processing, obtain all satisfactory optical fibre screen of face shape, size, its thickness can be used for making ultra-thin display screen below 5mm.Such optical fibre screen can be shielded as son, be spliced into large-area optical fibre screen, but, son screen at this moment should be processed into standard rectangular.Adopt glass material can make prepared optical fibre screen have good resistance to acids and bases and weathering resistance.Its limiting resolution of the optical fibre screen of Zhi Zuoing can reach 65～100LP/mm according to the method described above.
