Display) or output to an external video device through a connection jack for external connection.

One of the human sensory organs, the visual system prefers large-scale data unlike sensory organs such as ears, nose and skin. However, because portable electronic devices such as digital camera phones, digital cameras, and camcorders equipped with LCDs have small LCDs for displaying still images or moving images, users are not satisfied with them. Connect to the device to view still images or videos.

However, there is an advantage in that still images and videos can be viewed largely by connecting a separate large screen image device to various portable electronic devices. However, the greatest disadvantage of various portable electronic devices is the lack of portability. There is this. That is, since the large screen image device must be carried with various portable electronic devices, this method causes various inconveniences associated with the portable.

On the other hand, when a large screen is required in various meetings, lectures or seminars, a video projector is also used. An image projector is an optical projection apparatus that allows a user to enlarge and project a prepared image on a screen, and is very useful because many users can simultaneously view it in proportion to the width of the screen. These screens consist of vinyl chloride or synthetic resin fabric, which are usually rolled up and stored in a rolled manner and then used when needed.

Fifth, the glass beads are formed with different diameters to form concave-convex surfaces, and further include silver-based or pearl-based particles, thereby enhancing the high brightness on the front surface and securing the viewing angle from the side.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the circular recovery-reinforced portable display screen according to the present invention having the configuration as described above will be described in detail.

As shown in FIG. 1, the circular recovery reinforcement portable display screen 100 of the present invention includes a base layer 110 having a predetermined thickness and width that can be folded or bent by being composed of a fabric or a sheet such as wool, and In order to maximize the efficiency of the image projected on the base layer 110 is provided on the upper surface of the base layer, and the brightness enhancement layer 120 and composed of inorganic or organic particles for high brightness and reflected from the base layer 110 In order to secure the viewing angle of the light source, the luminance enhancement layer 120 is provided on the upper surface, and includes a reflection enhancement layer 130 composed of oral beads.

Although the base layer 110 is flat, the reason for being composed of fabric or sheet is as follows. First, when the base layer is composed of a stretch fabric, it is easy to carry because it can be folded or rolled around to minimize the volume regardless of size. In addition, since it is flexible, it can be immediately restored to a planar state even if it is folded, rolled up, and unfolded again. Second, if the base layer is composed of flexible wool or other fabrics, the surface may be somewhat curved, which may cause diffuse reflection. Fabrics are typically connected to a number of rings in a ring shape, the degree of bending is characterized by the gap between the thickness or the thickness of the ol.

In addition, as shown in Fig. 2, the knitted fabrics are inclined in the horizontal direction (a), and the longitudinal weft (b) in a row, the horizontal inclination (a) and the longitudinal weft ( b) meets each other at one point to form a mesh (c), and the mesh (c) portion where the weft (b) and the inclination (a) intersect is a spring shape and the weft (b) and the inclination (a) do not intersect. It is more convex than the planar portion, and has the property of exhibiting elasticity. The mesh (c) can adjust the elasticity according to the degree of intersection, this elastic force is to be the driving force of the circular recovery when the fabric folded and unfolded.

In the embodiment of the present invention, in order to enhance the function of circular recovery, the weft is organized in 20 to 50, the inclination is organized in 25 to 55, and the spring form is necessarily made only at the intersection of the weft and the inclined It may be configured by varying the shape of the spring or the degree of elastic force by various knitting methods. For example, it is also preferable to use a polyurethane-based elastic fiber yarn having a large property of returning to its original shape in response to external forces instead of using general fiber yarn.

In this way, when the base layer is made of a flexible fabric, even if the particles or beads have a regular shape, the fabric itself is irregular, so that the reflected light reflected by the incident light to which light is incident is also irregularly diffused. Accordingly, when the light is incident on a normal plane, the side angle of the reflected light according to the incident light becomes narrower, and the brightness becomes smaller as the angle is widened. In addition, by arbitrarily adjusting the interval, number or thickness between the ol can be unevenly changed shape is particularly suitable for improving the reflection efficiency.

For example, to expand or reduce the size of the screen, a frame for installing the fabric is separately manufactured. The frame may be made of carbon or fiber material to form a pole and then assembled in the form of a tent. In this case, a hole is formed at the corner of the screen, and then a circular ring is mounted. The screen spreads out in the form. It is easy to carry and store because the frame and fabric can be divided and carried, and the fabric can be folded and carried. Alternatively, if the memory alloy with excellent circular recovery is manufactured as a frame, and the fabric is installed in the frame, the circular recovery is always possible even after repeatedly folding and unfolding. In particular, when the frame is formed of a folding pole, and the fabric is installed here, the fabric and the frame can be folded and unfolded together so that it can be stored and transported integrally.

The brightness enhancement layer 120 is for enhancing the efficiency of the image, and is composed of inorganic or organic particles such as aluminum-based silver or mica-based pearl. The particles are characterized in that formed in a size of 5μ to 20μ. If the particle size is 5μ or less, it is difficult to realize a clear image quality on the screen when the light source lens is poor efficiency, and when the particle size is 20μ or more, more sharp image quality can be realized, but when the screen is folded and unfolded, It imposes a burden on the layer and breaks easily when the particles collide with each other. Above all, if the size of the particles is too large, it may be difficult to restore the original shape of the screen.

The luminance-enhancing layer 120 is to maintain a high brightness, in the same direction by adding an aluminum-based or mica-based layer that can cause reflection when the bead is usually uniformly formed in the reflection-enhancing layer 130 to be described later In order to optimize the efficiency of the image when looking at the screen by expressing a high brightness image of higher efficiency than when the reflected light is returned.

For example, when an image is displayed through the screen from an IT complex device or other video device such as a mobile phone, a large screen can be provided relatively larger than a small screen of the video device, but a light source lens is inserted into the video device. Even if it is used, when the power of the light source is too weak (50 o'clock to 200 o'clock), it is difficult to realize a clear image quality. Therefore, in order to enable high luminance image even if the power of the light source lens is weak, a luminance enhancement layer is desperately required.

In general, the white series is used, which gives a change in color and material for intensity of luminance. That is, in order to improve the contrast (contrast ratio) of the image, the color of black, blue, gray, etc. may be stirred and adjusted. Accordingly, the luminance enhancement layer of the present invention is intended to realize a portion in which the capacity of the ROM, such as RAM, is large, but the power of the light source is weak, in accordance with the ultra-light weight trend of the IT complex, and the material having excellent reflection brightness. Luminance amplification is considered through phosphorus aluminum or pearl system.

The reflection-enhancing layer 130, in order to solve the problem that the front brightness of the screen is quite excellent, but the side angle is narrow to secure the omnidirectional viewing angle, it is molded in the shape of beads, the size varies within the range of 20μ to 100μ It is preferable to form with beads. The reason for forming the concave-convex surface through the bead height as described above, although the brightness is enhanced through the brightness enhancement layer 120, by incidence of reflection by different reflections after incidence by inducing the angle of reflection in different directions In order to further widen the angle of reflection and improve the side of the image.

That is, in the case of the conventional screen, since the brightness is about 2.0gain to 3.0gain on the front side or about 0.8gain to 0.9gain on the side, there has been a problem that a difference of up to three times or more occurs in the front and side. In this embodiment, the function of minimizing the difference in luminance between the front and the side, and the size of the bead is formed differently to adjust the brightness of 1.5gain to 10.0gain in both the front and side.

Beads may in principle be spherical or close to a spherical cube, and even beads may be elliptical, hexagonal or diamond-shaped, with the exception of amorphous polygonal shapes with many corners. The surface may be somewhat rough. In addition, the beads can be made of a transparent material, both transparent glass, transparent acrylic or transparent PVC is possible.

The beads are variously determined within the range of 20μ to 100μ. If the particle size of the bead is formed to be smaller than 20μ, the focal spot is not formed in the bead and the focus is formed on the base layer or the back thereof, thereby reducing the reflection efficiency. Like the thickness of the inorganic because it is a fragile drawback and bead falling problem in the case of folding can have environmental difficulties. In addition, the focus is formed inside the bead and the front reflection efficiency is high, but the side reflection efficiency is low, so that light is not diffused.

In forming each of the layers 120 and 130, a hot melt binder layer 140 is further provided to closely fix each particle or bead. That is, each layer is attached and fixed to the upper surface of the fabric or silver-based by hot melt adhesive.

The hot melt binder layer 140, it is preferable to use a polyurethane resin (PUR) or polyester resin (PER) excellent in adhesion and flexibility. The hot melt binder layer 140 is formed to a thickness of 5μ to 50μ, it is necessary to make the thickness as thin as possible. This is because the hot melt binder layer requires two roles at the same time.

The first role is to attach the particles or beads to the top of the base layer or to connect the particles or beads closely together. The second role is to fold and unfold the circle. According to a feature of the present invention, the screen is repeatedly folded and unfolded, and when the folded and unfolded, the circular recovery to a flat state should be quick, and for this purpose, it is important to have flexibility and elasticity. If the binder for fixing the particles or beads is too thick, the flexibility is reduced and the folding is difficult, and the elasticity is reduced so that the binder does not immediately return to a planar state when unfolded.

In order to perform such a role, the kind of adhesive is not specifically defined, and an appropriate adhesive is used according to the use environment. However, when the above-mentioned polyurethane resin is used, it is effective in recovering the prototype because of its excellent flexibility and elasticity.

In addition, the step of further completing the flexibility and elasticity is a heat treatment condition. The above conditions are different depending on the physical properties of the adhesive, when the property is an aqueous system, 80 ° to about 100 ° is most suitable, when using an oil type is about 100 ° to 160 ° is most suitable. Therefore, in order to secure flexibility and elasticity, it is preferable that the heat treatment be performed in the range of about 80 ° to 160 °.

The present invention further includes an embossing layer 150 for maximizing circular recovery and improving viewing angle. The emboss layer is intended to simultaneously realize the function of circular recovery and the function of viewing angle improvement through structural changes. Therefore, the emboss layer 150 may be formed only on the base layer 110, or may be formed on the hot melt binder layer 140 to which particles or beads are fixed. That is, hemispherical embossing may be formed before hot melt formation or after hot melt formation.

However, when the hemispherical embossing is formed after hot melt formation, since unevenness is directly formed on the hot melt binder layer, the effect of increasing light diffusion and brightness is great. Therefore, even if the screen is viewed from various angles, the viewing angle can be dramatically increased.

The hemispherical embossing is preferably formed in a size of about 100μ to 1000μ, and the spacing between embosses is preferably formed in a size of about 0.3mm to 1mm. By forming the size of the emboss to 100μ or less, the elasticity of the circular recovery is given to the scratch phenomenon that occurs when the screen is first folded or unfolded. In addition, the reflected light source is irregularly changed due to the embossing secondary, thereby extending the viewing angle. Thus, the viewing angle at the side is further improved.

Hereinafter, a method of manufacturing a circular recovery-reinforced portable display screen according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 2, a base layer 110 made of fabric or film is prepared. Regardless of its type, natural or synthetic fibers, the warp and weft yarns intersect and the curved surface is cut into a predetermined size. In this case, when not only one person but also a large number of users view the size, the size is large and the size can be appropriately adjusted according to the use environment, thereby realizing a scalable service by one image panel.

As shown in FIG. 4, a hot melt adhesive such as polyurethane resin is applied onto the base layer 110. At this time, the base layer to which the adhesive is applied is heated to maintain the predetermined temperature, and the particles are sprayed in a heated state. It is better to repeat it several times than to apply it all at once.

The method of applying the hot melt adhesive on the base layer does not usually depend on the spray method, the roll method, the printing method or the transfer method such as spraying or spraying. For example, the particles may be sprayed onto the base layer as described above, and may be solidified using an adhesive. However, the particles may be formed into an integral film and then attached onto the base layer.

As shown in FIG. 5, after the luminance enhancement layer 120 is formed through the hot melt adhesive, the reflection enhancement layer 130 is laminated. The reflection enhancement layer 130 is fixed using a hot melt adhesive like the luminance enhancement layer 120.

The heating temperature of the hot melt adhesive is suitably 80 ℃ to 160 ℃. If the heating temperature is 80 ℃ or less, the viscosity of the adhesive is low, the beads do not bond to a sufficient depth to lose the adhesion. On the contrary, when the temperature is 160 ° C. or more, the hot melt adhesive is almost liquid, and the degree of impregnation of the particles is so great that the beads are submerged under the adhesive, thereby preventing the reflective function.

As described above, the concave and convex may be formed by changing the diameter of the bead, but in the embodiment of the present invention, the concave and convex may be formed by adjusting the impregnation depth of the bead. Therefore, in order to make the surface shape more irregular, the thickness and viscosity of the adhesive are adjusted so that even the same size of the bidder can be impregnated at different depths. Although the thickness of the adhesive is appropriately determined in consideration of the size of the particles or beads, it is preferable that the thickness of the adhesive does not exceed the range of 50μ for flexibility and elasticity of the screen.

The beads are sprayed and heated on the adhesive, and then the adhesive is dried to a predetermined temperature using a hot air blower. In order to enhance the fixing force of the beads described above and to increase the degree of curvature of the surface, it is preferable to heat at the above temperature for 30 minutes or more, and to mature at room temperature for at least one week.

As shown in FIG. 3, the emboss is formed directly on the base layer 110, or the emboss is formed on the hot melt binder layer 140 after laminating particles or beads by an adhesive. The emboss is formed using an embossing roll formed with a plurality of irregularities on the outer circumferential surface.

As described above, the present invention is composed of a fabric that can be folded or unfolded, in order to meet the contradictory requirements of light and short and large screen of the screen, when we folded and unfolded, weft and The spring structure is implemented at the intersection of the slopes, and the hot melt adhesive that fixes various beads is made of a material having excellent flexibility and elasticity. The emboss is formed using a roller on the cloth, and the beads are used to improve the efficiency of the image. In the case of attaching, it is known that the bead is mixed in different sizes, the surface of the screen forms irregularities in the state in which large and small beads are fixed to the adhesive, and further includes aluminum-based particles. Can be. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.
