Abstract

A light guiding panel on which minute recesses are formed by a sandblasting process, a backlight unit using the panel, and a method and apparatus for manufacturing the light guiding panel are provided. On the bottom surface of the transparent acryl resin substrate of the light guiding panel, countless recesses that cannot be seen with the naked eye are formed to reflect source light which is incident on a side wall of the substrate, to the front of the panel. These minute recesses are formed by a sandblasting process. In particularly, as a distance from the side wall on which the source light is incident increases while the amount of minute particles injected per unit time is uniformly maintained, the number of sand particles impacting on a unit area of the bottom surface of the substrate per unit time and the impact power gradually increase. Accordingly, as distance from the vicinity of the side wall on which the source light is incident increases, the density, average depth and size of minute recesses all gradually increase. Also, the area of occupancy by minute recesses, the complexity of the contours, and the average complexity of the recess surface profiles increase. Therefore, since the light emits from the front surface of the light guiding panel is uniformly diffused light, if the light is applied to construct a backlight unit of an advertising film or an LCD panel, a diffusion sheet is not required.

200420923

[Technical Field to which the Invention belongs] The present invention relates to a light guide plate, and the fourth temple relates to a light guide plate with micro recesses, forming a gradient pattern on one surface of the panel, and improving the uniformity of the brightness of the panel, and There is no need to use a light diffusion sheet. [Prior art] Liquid crystal display (LCD) panels or advertising plastic films cannot emit light by themselves' requires a light element to achieve the display function. The light guide plate is one of the main elements forming the backlight element, and the light of the conversion lamp tube becomes the light of the planar optical light source. According to the position of the optical light source, a method of forming a backlight element can be divided into a direct-type method or a light guiding panel method. The direct method directly sets an optical light source under the light emitting surface to ensure that plane light is emitted. The light guide plate method is to place an optical light source on one side of the light guide plate, so that the light incident on one side of the panel can be guided and reflected on the front surface of the light guide plate to ensure that flat light is emitted. The invention applies the light guide plate method described above. The know-how of manufacturing the light guide plate of the backlight device of the LCD includes a dot pattern printing method, the use of silk printing technology 'and the V-cut method, and the use of a mechanical tool. In the silk printing technology, the dots are formed on the bottom surface of the light guide plate by using the silk printing technology, and tiny glass beads are placed in the points, so that the light is scattered on the surface of the glass beads, and the scattered light passes over the upper surface of the light guide plate. This method is a stable technology that has been used for many years. During the engraving process, the resolution of film, tension, and angle of view

Many key technologies are needed to confirm and adjust the above correlations. In addition, the printing process is quite complicated, and during the printing process, there will be many defects. In the v_cu1: method, a V-shaped groove is directly formed on a transparent acrylic resin (commonly known as acrylic resin) substrate through a mechanical tool, so that the light incident at one end of the panel is reflected on the front surface of the light guide plate. However, in the guide plate formed by the dot pattern printing method or the V_cut method, the scattered light reflected by the dot or V-groove is emitted to the moon surface of the light guide plate, so that the reflection pattern is displayed on the guide plate. Light board. In other words, because the size of the reflection pattern reflected by dots or V-shaped grooves can be seen by the naked eye, it is called "light spot" formed on the front surface of the light guide plate. In the light spot, the dagger and the dark part are partially mixed. Or both. If the light spot cannot be removed, such a light guide plate is not suitable as a backlight element. In order to remove the light spot, a diffusion plate (di f 仏 “⑽ f two diffusion plates plus a prism sheet) is usually connected to the light guide plate. The uniformity of brightness. However, the light transmission coefficient of a diffuser is usually about 68%. The use of a diffuser or the like will reduce the optical efficiency and reduce the brightness of the backlight. Efficiency 'requires a light guide plate' Λ light guide plate does not need = political board or other similar. Because & 'Research has been carried out in recent years, research includes the direct use of a mold to make a transparent resin substrate (a part of the plate is directly cast- Square of light guide plate with light dispersion function

It is not clear, but the establishment of it, including the low conductivity, has reached the same degree of certainty. However, Xi needs. In addition, method factors such as formation and groove depth must be used. [Summary of the Invention] In order to solve the upper light guide plate, the visible light spot can be more optically efficient than the first light element of the present invention. It is through the stage of production, the light guide plate to the light guide, the light guide, the use of light guide is appropriate, and there is no evidence of laser, spray, and can be made of light-absorbing plates. On concave conditions. However, the technology that hinders the above-mentioned sand or invasion to show the production of consumer products and light has not been used. However, the purpose of the technology in the treatment of insects needs to achieve the uniformity of the film. Still not on the market. However, this can be applied to light guides. The reason is that the mass production system reduces the production cost and the stability of the brightness satisfies the above-mentioned backlight elements, and the average size has another problem that can achieve success. The present invention distributes light uniformly even if it is not necessary. The second purpose is to provide the first purpose is to provide a diffusion plate that does not occur to the naked eye and achieve high uniformity of brightness.

In addition, 'in the light guide plate, the farther away from the vicinity of the face where the light is incident', the average complexity of the contours of the grooves and the surface contour of a groove gradually increases. The groove of the substrate in the light guide plate is formed by a sandblasting method. The grooves of the substrate 2 are formed by a sand blasting method. In the sand blasting method, a fixed amount of fine particles are sprayed for a time unit. As the distance from the vicinity of the surface where the light is incident, the In the unit of time, the amount of sand hits the area of one unit of the bottom surface of the substrate and the impact of sand gradually increases. In addition, in order to maintain a fixed amount of fine particles to be sprayed, the fine particles are freely dropped during the injection molding process of the fine particles. In the light guide plate, the groove has an extremely minute size that is hardly visible to the naked eye 'and even if a diffuser plate is not provided, light spots visible to the naked eye do not appear on the front surface of the light guide plate.

[Embodiments] Hereinafter, each embodiment disclosed in the present invention will be described in detail with specific examples. As shown in Figs. 1a and 1b, according to one surface of the light guide plate of the present invention, (the bottom surface is referred to herein), the distribution of the grooves forming a gradient pattern in the grooves varies depending on the incident light method. . In m two plate 3 ", light guide plate 3. Both sides _ follow the U 'light guide plate 35. One side 35a is the light: the light guide plate shown in Figure I is used to help understand the book == ;; Banming' must also pay attention to the light guide plate (such as the second time) Zhao film is different. In a real light guide plate, the sample system cannot be yours.) It is located on the recess on the bottom surface of the light guide plate 40: the position f: the dead eye is watching. So ‘look at the area with the grooves formed in degrees) when the mold shed & except I /, you have measured the set width while simple, and it is confusing and translucent. Those who have measured a considerable number of test articles, the light spot of the invention of the present invention, the light spots are tied together ::, even if no diffuser is used, ... to avoid: the reflection pattern on the bottom surface of the light guide plate, 5152-5658-PF ( Nl) .Ptd Page 14 200420923 V. Description of the invention (9) 将 will show the highly consistent brightness on the f front surface. Conditions for the shape of the groove on the bottom surface of the well and plate when the light source is turned on. As the distance from the light guide c decreases significantly, this principle can also be applied. To make the bottom surface of the light guide plate brighter, the groove characteristics on the surface of the coupon must meet the following conditions. Near the source m: the groove: when it is on the bottom surface of the light guide plate, 'must be at the light inch, and at the same time the groove density, average depth, and average depth of the number of second fathers, and when the distance is gradually away from the money, you can change The groove density and the average number are gradually increased as the value of θ # t average size, so even though the light intensity is reduced, the light can be reflected on the bottom surface of the light guide plate. The condition of the cup is also stipulated that when the distance from the light source (tube lamp) increases, the density of the groove on the surface, the average depth, and the average ruler w have been increased. When the distance from the light source increases, the density of the groove, the average :: 2 乂, and the average size increase and then decrease, and the silk is generated at the 4th place where the change occurs. Therefore, the step of forming the grooves on the light guide plate must be full.纟 In the description of the conventional technique, 'a micro-groove has not been found thereon. Because the manufacturing method of the hand meets the above conditions, the second condition is that the groove size on the bottom surface of the light guide plate must be small enough to be invisible to the naked eye. This is because if the groove size is not so small, when looking at a certain area 'Sun, moon, and dark places will mix and co-exist-so' you will see light spots. The dot will affect the light guide plate, which does not use a diffuser on the backlight of the liquid crystal display or transparent film for advertising. 5152-5658-PF (Nl) .ptd p. 15 200420923

Figure 2 shows the conditions for using a digital camera to capture the outline of a groove. (In the second picture, the guide plate 40 is made to meet the position where the light guide plate is transparent. I light plate 4G'G has a groove, but it must be considered that the light guide plate is translucent. , Because when shooting, the stagnant color ::: shape is not fully expressed as shown in the light guide plate in Figure 1 = placed under the light guide plate). In this system-a light source, mounted on a two-m light board 4G has a labor light and a light guide plate 4. The bottom surface is recessed in order to find samples (42a to 42g) that are really different, ‘? :;? : Inch :: The month is from the center of the light guide plate to the left. · ,, /] Samples are appropriate, the sampling direction is a predetermined range of sampling, and multiple methods are used to measure the bottom table. Taking pictures with a scanning electron microscope, the figures 3a to 3g show seven different samples (42a to 42g). In these films, it can be seen that the grooves are bright, and the dark parts indicate the places where the grooves are formed. Also, it can be seen that from the photo to ", the density and size of the grooves gradually decrease, that is, from the center of the light guide plate 40 to the left. ^ For more detailed observation, seven samples The pre-λ σ 卩 position of the three-dimensional surface is photographed, and the results are shown in Figures 4a to 4g. From these photos, in addition to the groove density and size, it can be determined that from the left to the center of the light guide plate, the groove The depth will also gradually increase. Figures 5a to 5g are measured at 8 mm intervals on seven samples.

Data for measuring j-plane brightness. For all the measurement intervals of each sample, the mathematical mean derivative of the contour is Ra ′ and the maximum height is Ry, as shown in the following table:

From these data, it can be seen that from the left to the center of the light guide plate 40, the mathematical mean derivative gradually increases, and these measurement results also conform to the above-mentioned change pattern of the groove average depth. Although the values of samples 5 and 6 are opposite, it can be considered as an exception to the characteristics of a blasting process. From the perspective of probability, it can be ascertained that as the distance from the light source increases, the Ra and the heart value will gradually increase, which conforms to the change pattern of the average depth of the grooves. Fig. 6 is a pattern of a preferred embodiment of a backlight element used in an advertising film to which the light guide plate of the present invention is applied. In the backlight element, when power is provided, at least one side of the cold cathode fluorescent lamp 10 and the light guide plate 30 or 35 are parallel to each other, and a reflective cap 2 surrounds the fluorescent lamp and reflects the fluorescent lamp 10 The light reaches the light guide plate 30 or 35 and is placed on the back of the fluorescent lamp 10. On the bottom surface 32 of the light guide plate 30 or 35, a minute groove is formed like the above pattern. The bottom reflection plate 20 and the side reflection plate 22 are interconnected on the bottom surface 32 and the side where the camp light 10 is not installed, so that the light emitted from the light guide plate can be reflected back to the inside of the light guide plate. The advertising film 26 is directly connected to the front end surface 24 of the light guide plate 30 or 35. These places

200420923 V. Description of the invention (12) Some objects are composed of a frame by a frame 2 4. The light generated by the fluorescent lamp 10 passes through the sides of the light guide plate 30 or 35 and enters the inside of the light guide plate 30 or 35. The incident light at different angles is emitted from the uranium end surface 34 of the light guide plate 'or is incident on the bottom surface by reflection. The light incident on the bottom surface illuminates the groove. According to the contour of the groove, the incident light irregularly scatters or passes through the bottom surface, and is then reflected by the reflecting plate 20, and then passes through the bottom surface again and is scattered. Through the complex reflection and scattering processes described above, light can be emitted to the front end surface 34. In the light guide plate 30 or 35 of the present invention, the light passing through the front end surface 34 is a sufficiently uniformly diffused light, and the pattern reflected by the groove cannot be seen by the naked eye, so a diffusion sheet of conventional technology is not required. Because the light guide plate does not use a diffusion sheet, the advertising film 26 becomes brighter and clearer. Therefore, in the advertising effect, the use of a diffusion sheet without a diffusion sheet has a comparative advantage over the use of a diffusion sheet. Advertising films are manufactured using transparent films or translucent printed films with light diffusion. The light guide plate of the present invention has an excellent display function under any of the examples. If the light guide plate of the present invention is applied to a backlight element on a liquid crystal display panel, a uniform diffused light in the light guide plate can be obtained, and therefore, another diffusion sheet is not required. "Figure 7 is a digital photograph of a light guide plate 50 produced by the light guide plate 40 of the present invention and the dot pattern printing method of the conventional technology by using a digital camera and a same fluorescent lamp 10 Shooting. In the light guide plate 50 produced by the dot pattern printing method of the conventional technology, the size of the dot pattern can be seen with the naked eye, so unless a diffusion sheet is used, the dot pattern will be seen.

200420923 V. Description of Invention (13). Meanwhile, in the present invention, even if no diffusion sheet is used on the front surface, the light plate 40 can still provide natural and uniform diffused light. FIG. 8 is a digital photograph, and a transparent film ⑼a is placed on the light guide plates 40 and 50 in FIG. 7 by using a digital camera. As in the photograph, in the light guide plate 50 produced by the dot pattern printing method using a conventional technique, even if a transparent film is placed on the light guide plate 50, the dot pattern can be seen with the naked eye. Therefore, the 'light guide plate 50' is not suitable for backlighting using advertising films made of transparent films. Figure 9 is a digital photo. Using a digital camera, the semi-transparent advertising film 60b and a film company with a light diffusion function are started, and then placed on the light guide plates 40 and 50 in Figure 7.

Therefore, in the opening _ septum of the penetration hole 200 ×, the injected particles fall like a free fall. 2 Use a Gabriel fluid, such as pressurized air or water, to pass through the pressurized fluid supply tube 2 0 0 d and then spray the $ 9 leigh 9 η η ^ + 'production, white ± "He Bird 2 0 0a, south The low-pressure ring produced by Suga Shot = 月 聒 # μ The injected particles under the pull pull and pass through the particle supply tube 2 0 0 f it rides 00e and then into the cavity 20 0y, then mix the injected particles and the body together 'Then it is injected through the nozzle 20〇a to the outside 0. Only the surname ^ I ί 疋, the particle injection device 2 of the present invention is always solid for time: the injection of particles *, and the injection of particles per unit time For the traditional injection device, I wish that the relative advantages of the injection device 2000 of the present invention are not lost. For time, the reason why a fixed amount of injection particles can pass through the nozzle 200 &amp; When the injection particles flow to the penetration hole 20 (^) of the connecting member 200, the injection particles will fall vertically, like an hourglass. The reason why the injection particles can be free and fall is because of the opening 2 〇〇h and 200h, formed on the connecting member 2000. Due to the small particles Characteristics, micro-particles do not have good cooling properties, so an injection device using the vacuum inhalation method according to Bernoulli, s the〇; rem'IL, is widely used in the conventional technology. If one is not provided in the supply injection On the path of the particles, this component is used to allow air to flow in to avoid the generation of a high vacuum. When the pressurized fluid flows through the nozzle 200a at a high speed, the low pressure environment, which is a vacuum bear.

200420923 V. Description of the invention (18) In addition to the gravity change, due to the pressure change caused by the high vacuum, it is responsible for inhaling the injection particles of the container 2011 to the penetration hole 20 (^) of the connecting member 2000. It will become stronger. This powerful suction power is applied across the entire supply path, from the aperture 20 i to the nozzle 200a. Then, as it advances along the supply path, the strong suction particles strongly hit the wall or It collides with surrounding particles, so the speed will change due to friction. Especially because the amount of pressurized fluid changes with time when the pressurized body passes through the pressurized fluid supply tube 2000d, so the nozzle The density in 2000a will also change. The change in density will cause the pressure of the supply path to change. Therefore, the amount of the small particles and the pore diameter 2 0 i will be inhaled. As such, the mutual influence remains It will continue. Therefore, if the amount of micro particles injected from the nozzle 20a or the injection speed becomes uneven, it will be difficult to form grooves, like a gradient pattern, on the surface of the transparent substrate 140. "However In the present invention, if the openings 20Oh and 20 Oh connected to the particle supply path are formed on the connecting member 200g, even in the low-pressure environment generated by the high-speed ejection of the pressurized fluid, the air can be continuously From the outside = through the openings 20h and 20h for supply and replenishment. Therefore, the low-pressure environment is only formed at the openings 2000h and 2000h of the penetration hole 2000x, and the atmospheric pressure is still high below Due to the pressure in the traditional method, and especially in the openings of the penetration holes 2 ^ 0 = 20h and 20h, there is no low atmospheric pressure at all in the upper range. Therefore, the pressure change is used to inhale the particles forcefully. It does not happen, only particles that fall freely by relying on the gravity of the earth will happen. After passing through the opening 20 Oh and 20 Hour ', the free falling particles will be strongly pulled and injected from the nozzle 20a .

200420923 It is possible by falling. Therefore, the volume of the body will be followed by a number of sprays with a diameter of 2000i. Except for the product, the spray is arranged straight and the distance is the same. Note that the particles are provided. Although the spray has changed, the time is fixed and the internal fixation is changed. The size of the amount, just the mouth, can also be other than that, the uniformity of the nozzle device 110a and the quality of the light guide plate from a transparent base at a set angle is broken using special particles (s or diamond particles and can be the best These conditions are five. Explanation of the invention (19) If you can leak the pre-micro particle volume supply pipe 20 0d that has changed in time from the same principle, keep the micro particles in the injection volume. Even if you control each spray and time consistency refer to The eleventh direction and the downward direction of the conveyer are tilted when watching. The raw materials used to make the enoic acid group can not be used for injection of carbonide, carbon (zirconia), and are not limited to the density particles of the above plate material. Also, particles. Satisfy this to establish the free fall, set the particle amount in a short pressurized flow, once set, use the adjustment hole is to install the compound nozzle injection can be raised to Figure 13, vertical to each other, the injection side of the raw materials and processing. In other words, the type of particles that can be used in i1i con, the most suitable particles for effective use will be like a sand supply tube 2 0 f — 2 0 0 a injected with the mouth because it is rheologically pressurized, but it can be guaranteed to be accurate Ground control is easy and the controllability and reproducibility of accurate shots. To 11 Od, the front surface of the injection square plate 140 is oriented toward the incident light surface. A transparent resin substrate, for example, in the present invention, a base can be fully used to use a carbon alloy (a 1 uminum carbi de) and hafnium oxide. As long as the type of particles used is a groove with a hardness greater than that of the transparent base, this type of injection with high uniform shape and size can be used as the diamond type diamond particles. diamond

The granules have good fluidity, so they can be smoothly supplied, because the impact of the granules during the supply process from the granules to the nozzles, the size of the granules will have high consistency and will not generate a lot of dust. It is best to use a particle size between # 100 and # 200. Formation of the grooves on the surface of the transparent substrate using the above-mentioned device will be explained next. First, first cut the transparent substrate into a desired size, and then place it on the transfer line of the transfer device. By controlling the conveying device 10 0 #, the transparent substrate 140 is conveyed at a preset speed. At this time, the particles can be injected on the transparent substrate 14 obliquely by manipulating the injection 1 to 20 0 ′. On the same day, in order to reduce the dark place on the side of the light guide plate, commonly known as H — ~ special ', you can consider when the particles are injected into the side of the transparent substrate 14 0'! The transfer speed can be reduced, so more grooves are formed on the side. After the process of forming the grooves is completed, the substrate is transferred to the processes of cleaning, drying, and inspection. Figures 15a and 15b show the process of forming grooves in the light guide plate. In the light guide plate, the incident light surfaces 142a and 1421) face each other, such as the light guide plate 30 shown in FIG. For the convenience of description, in Fig. 15a, two nozzles 110a and 110b inject particles on the right half of the transparent substrate 14o during the transfer. However, the other two nozzles 10c and 0d form grooves on the left half of the transparent substrate 1 40, as shown in FIG. 5b. Although all four nozzles are shown in the figure, this is just an example. The number of nozzles can be determined from the size of the transparent substrate. The first nozzle 110a and the second nozzle 110b are located on the diagonal of the x-y plane, and their injection areas 144a and 144b overlap a little and cover

5152-5658-PF (Nl) .ptd Page 26 200420923 V. Description of the invention (21) Right half. The positions of the third and fourth nozzles 110c and 110d cover the left half, and correspond to the positions of the first and second nozzles 110a and 110b. In one method, by arranging the nozzles 110a and 110b, as the distance increases from any of the surfaces 142a and 142b of the incident light, the number of grooves also increases, and, in a unit time, from the first The number of particles injected by the third and third nozzles 110a and 110c is preferably greater than the number of particles injected from the second and fourth nozzles 110b and 110d. In another method, the injection pressures of the first and third nozzles 110a and 11c may be greater than the injection pressures of the second and fourth nozzles 110b. In addition, the above two methods can be combined and applied to adjust the particle injection volume and nozzle injection pressure. Tilt the vertical direction of each feed direction from the transparent base θ λ &gt; {71 The sound will also reduce the depth and also the number of wide grooves from the nozzle, and, when possible, the contour will follow, such as the nozzles 110a to 11 at the bottom of the light guide plate After 〇d is installed, the injection direction will be straight and straight, and will be inclined toward the surface of the transparent substrate 1 4 〇. If injected, the angle at which the small particles are incident on the transparent substrate 4 will also decrease as the distance from the plate 140 to the nozzle increases. Because (redundant / 2) — / 2) ~ 02, the small particles have less effect on the transparent substrate. Therefore, the size of the groove 7 formed on the surface of the transparent substrate 140 decreases as the distance from the nozzle 20 0a decreases. In addition, since a is a general injection of particles, the depression in a unit area of one of the transparent substrates 140 is also the density of the groove, and 纟 will decrease as the distance from the nozzle decreases. : When the distance from the nozzle decreases, the stroke increases in the same place. Therefore, the size of the groove is very large, and the size of the life cycle is Φ. ^ The size and size of W are large and combined with the nearby grooves i: ϊ: ί ϊ * The complexity of the surface profile will increase. The shape of the process can be used to obtain the contour of the groove on the surface.

200420923 V. Description of the invention (22) Figures 16a to 16c show the process of forming grooves in the light guide plate, which has an incident light surface 142b, two nozzles 110a, and 11 0b. ', As shown in Figure 1b. If the size of the transparent substrate becomes small, only one nozzle is sufficient. The two nozzles 11 〇a 'and 1 1 Ob' can be arranged on the diagonal of the x_y plane, as shown in Fig. 16b, or arranged in a row in the y-axis direction, as shown in Fig. 16c Show. When the nozzles are arranged as shown in Figure 16c, in order to obtain the groove gradient pattern, it is best to use the second nozzle 11 〇b, the injection pressure and injection volume of which is smaller than the injection pressure and injection of the first nozzle 11 0 a ' the amount. When the nozzles are arranged as shown in Fig. 16c, if the injection angle 'can be adjusted appropriately, it is sufficient to apply the same injection pressure and injection amount to the two nozzles 110a' and 110b '. Next, a second preferred embodiment of the manufacturing apparatus and the process of the present invention will be explained. According to the present invention, Fig. 17 shows a second preferred embodiment of the structure of a light guide plate manufacturing apparatus. The second embodiment uses a vertical and diffusive blasting method, which uses a built-in nozzle. When compared with the manufacturing device in the above figures ii to 13, the embodiment of the device is not different in the structure of the conveying device 100, but there is only one basic difference, that is, the injection direction does not face the transparent substrate. 4 〇The surface is inclined but vertical. The plurality of nozzles 3 l0a to 31i are arranged in a direction perpendicular to the conveying direction of the conveying line on the conveying strip 128. The nozzles 31a to 31i are sprayed from below the surface of the transparent substrate 140 and the spraying direction is perpendicular to the surface of the transparent substrate. "In addition, as the distance increases from the incident light surface, the groove distribution and size also increase. The nozzles are installed so that when the distance increases from the incident light surface, the interval between adjacent nozzles is reduced. Figure 丨 7 shows a light guide plate

200420923 V. Description of the invention (23) &quot; &quot;-As an example, the two sides of the light guide plate are incident light surfaces, and it is also shown that the distance D2 between the nozzles 310h and 310i is greater than the distance D1 between the nozzles 31 d and 31 oe. Stomach, when the nozzle is to be placed, different injection volumes and particle pressures can be applied. In order to achieve the groove profile of the light guide plate in the present invention, as the distance increases from the position where the light source is placed, the injection amount and particle pressure of the nozzle covering the corresponding area will gradually increase. In order to obtain the desired groove profile, a method of adjusting the nozzle interval may be appropriately used. As shown in the device in Figure 17, a blank space where particles are not injected may occur between adjacent nozzles. In order to reduce the blank space and produce a grooved gradient pattern, when injecting particles, the nozzle must be swung one direction perpendicular to the conveying direction. Therefore, the nozzle is connected to the horizontal adjustment bar 122, the horizontal adjustment bar 122 is fixed on an LM guide 350, and a servo motor 360 is connected to the LM guide 350. Because of the right chess game, the servo motor 360 swings the LM guide 350-the direction (in ^ right ^) is perpendicular to the transmission direction of the transparent substrate 丨 40. Therefore, the 'nozzle can inject particles uniformly on the entire surface of the transparent substrate and produce a blank space. Geyuezu Figure 18 shows a 300-particle vertical injection method of a particle injection device. The particle injection device is different; the injection 1 is set to 2 0 'The difference is that the nozzle 31 ° is injected from below. Otherwise, the particle supply hole 200e is connected to the nozzle body 300c. The fluid supply hole 3 0 0d is curved. It's about 90 degrees, and it's a plus, ^ ^ ^ ^, II is connected to the side of the nozzle body 3 0 0C: In addition to 2 differences, other characteristics like particles are supplied from the nozzle to the nozzle 3 10 is the same as the particle injection device in FIG. 14.

200420923 At the same time, using acrylic resin-based resin substrates with a size of 3 09 mm x 23 6 mm, the inventors carried out the process of forming the grooves by using the manufacturing apparatus of the oblique injection method in Figs. 11 to 14 . The state of the manufacturing process is described in the following table 2. The transmission speed of the acrylic disk-based resin substrate is 900 mm / min. The angle between the nozzle and the surface is 7 degrees. The nozzle pressure is 6 kgf / cm2. Injected granite (# 150: 0 ~ 150) The injection volume is 0.4 1 / min. Fig. 19 is a photo taken by using a microscope on three places on the surface of the light guide plate 30 (30x, 30y, 30z; as shown in Fig. 5a). The production of the light board uses the oblique injection method to process the acrolein-based resin substrate. As shown in the three-place distribution photos, in the area 35χ, the groove ^ distribution has 54 grooves per square millimeter, and the area 35χ is close to Incident light surface 30a, and in the inner regions 35y and 352, the number of grooves will gradually increase to 120 and 18 respectively. Also, it can be determined that the farther away from the incident light surface 30, the size of the groove The depth of the groove will also be gradually increased. If light is incident on the light guide plate, the brightness of the light will be guided uniformly throughout the light guide plate. Figure 20 shows a result, by incident light on the surface of the light guide plate incident light The results of measuring the brightness of the surface of the light guide plate in 40 0a and 40 0b. The brightness range is between the maximum 76000 1χ and the minimum 6800 ΐχ

A transparent substrate 580 is placed on the transfer device 600, and the 600 transfers the transparent substrate 58 in one direction. The transfer device 60 ( ) Yes, you can say that the two are unified. Also: a pair of guide rails _f and 6_ space-Erfan Yuewei Each other, a conveyor 600k is installed on the outer surface of the guide. One end of the rail 60g is equipped with a motor 600a and gears 600b and 600d, which is connected to the motor 600. The main axis of a and the rotation power of 60 0a are transmitted to the two guides 600f and 60f, so the belt 60k will rotate. By vertically crossing two = rails

200420923 V. Description of the invention (26) 600 f and 600 g sides, the guide bar 600k &amp; 600m holds the guide rail 600f & 600g, so the two guides are maintained A preset range. At the same time, if an external force is applied to the guide rail, the guide bar will slide and support the guide rail, so the distance between the guides 6 f and 600 g can be accurately adjusted. In addition, there are motors 60 0 i-1 and 6 0 i-2 and gear shafts e 00h and 6 0 j installed to adjust the distance between the guide 60f and 600g. The gear shaft 6 0 0 j extends toward the axis of the motor 6 0 0 i-2, and the gear is combined with the guide. At the same time, the gear shaft 60 0h extends toward the axis of the motor 6 0 i-I, and the gear and Rail 60 0 f combined. If the gear shafts 600h and 600j • are rotated by driving the motors 600i-1 and 600i-2, the guides 60f and 60g can be pushed or pulled. The distance between the two guides can be adjusted. It is best to carefully design the distance between the two guide rails 600 f and 600 g so that it can accommodate the largest size transparent substrate. The transparent substrate 580 is placed on a conveyor belt 600k which surrounds the outer surfaces of the guides 600f and 600g. In order to avoid the transparent substrate 580 from being bent due to the strong injection pressure of the small particles, a support plate 582 that can withstand the maximum injection pressure and will not bend is placed on the transfer bar 600k, and then the transparent substrate 580 is placed on the support plate 582 on. In order to form a desired groove pattern on the transparent substrate 580, a function of controlling a transfer speed may be provided. To this end, a control unit 6i0 can automatically control the transmission speed. In addition, at a suitable position on the transmission line, for example, in front of or behind the injection tube 5 10, induction devices 584a and 584b are installed to detect the passage of the transparent substrate 580. The control unit 61 controls the transmission speed by using detection signals of the inductive devices 5 8 4 a and 5 8 4 b.

5152-5658-PF (Nl) .ptd Page 32 200420923 V. Description of the Invention (27) In order to fill the function of the unit 610 in the manufacturing process of the light guide plate. For the automation of the knife, it is necessary to expand the control and use the grasping motor, and all motor systems with a force device: the operating conditions set by the user to automatically control; according to the next description, the particle injection device 5 9 〇 士 置 5 90 includes-a container 540 for storing tiny particles and particles: from y: filled with small particles, freely falling through the outlet 542 to the empty ^ green micro-system from the container 54. Free fall, tiny particles ==, tender and solid I I apply to the previous two real masters. It is best to install the switch control unit 544 on the outlet 542. Second: = "When: Turning on," you can release tiny particles by opening the outlet. To make early 544. You can use-solenoid valve. Also, $ 了 使Tiny ^ It is easier and smooth to fit from the container 540. It is best to install the vibrator 540 used to vibrate the container 1540 on one of the outer walls of the container 540. High-speed flowing air is mixed. To this end, a mixing conveying unit uses a device to manufacture high-speed flowing air and discharge mixed particles from the outlet, and sucks freely falling particles from the inlet into the mixed particles in high-speed flowing air The mixed particles are then discharged from the outlet. A blower can be used for the mixing and conveying unit. The figure shows a structure having two blowers 5 2 0 and 5 3 0 connected to each other. Each blower 5 2 0 and 5 3 0 has an approximately cube Internal space and entrances 522 and 532 and exits 5 24 and 534. Motors 526 and 536 are installed inside 5152-5658-PF (Nl) .ptd Page 33 200420923 V. Description of invention (28) Part space Inside, and a motor is installed outside the cube space, the central axis of the motor is connected to the rotating wheels 526 and 536, and the rotating two wheels 52 6 and 536 can be rotated at high speed. By rotating the motors 528 and 538, ^ Make the rotating wheels 526 and 5 3 6 rotate at high speed. Therefore, the small particles freely falling near the inlet 522 of the first blower 5 will be drawn into the inlet 52, and then the small particles will collide with the rotating wheels 5 2 6 And mixed in high air, and finally discharged from the right outlet 524. mixed with air j: after being discharged from the outlet 524, it will then be transmitted by the second and second pass; i is discharged from = except for the one shown in the figure Structure, construction: One, three, or multiple hair dryers can be used for the second pass k., Guang: Not shown in the figure 'by using a duct with an opening and two upper ends, and an air pressurization device , Such as a compressor, is connected to the surface of the moon and supplies high-speed pressurized air to the outlet of the duct and the delivery unit. Although this nozzle has been used in the previous two embodiments, this is for you about the small particles from Mixed pass The thin funnel-shaped injection shell of the delivery unit is ejected. Note that the inlet 51 and the outlet nozzle 512 of the tube 51 are connected to the outlet 5 34 of the mixing transmission unit. The internal cross-sectional shape of the note is shown in the outgoing direction. The thickness and width of MU Μ are gradually reduced. It is best that the exit 51a of Shezhuang Shelu 51〇 is placed on the substrate 580 and passes under the exit 510a. After falling freely, the particles will interact with high-speed flowing air, Said you, t ^ UJ m shot. The mixing delivery unit shot tube 510 is a high-speed injection tube 51 of this shape. "0 此 射" granules pass through the mouth, the cross-sectional shape, through the exit 51〇a

200420923 V. Description of the invention (29) The aggregate formed by the injected small particles can be defined by the internal cross-sectional shape and the cross-sectional shape of the injection tube 5 10. The cross-sectional shape of the small particle group of the injection tube 5 〇 can be determined by the groove distribution pattern formed on the transparent substrate 580. In order to improve the production efficiency, it is best to pass the transparent substrate 5 8 0 once below the injection tube 5 1 〇 to form the desired groove °. Also, it is preferable that the exit width of the injection tube 51 0 is not smaller than the transparent substrate 580. Of its width. It is preferable that the exit of the injection tube 510 covers all widths of the transparent substrate 580 ', and the transparent substrate 5 8 0 passes below the injection tube 5 1 0. At this time, the groove distribution of the transparent substrate 580 changes according to the position on the surface of the transparent substrate 58. Basically, the groove distribution density increases as the distance increases from the position of the light source. Because the groove distribution density is proportional to the number of particles passing through the inside of the injection tube 5 10 within a unit time, the groove distribution can be adjusted by changing the shape of the guide, that is, changing the injection tube 5 in the width direction.丨 〇 the thickness. When the thickness of the transparent substrate 580 has variability, it is possible to increase the thickness of the injection tube 5 1 〇 in a region where the groove distribution density is smaller than that of the trough, and to reduce the thickness of the injection tube 5 1 0 in a region where the groove distribution density is lower. . If sand injection is performed by using this injection tube 5o, the groove distribution map of the light guide plate of the present invention can be obtained. In other words, when the particles are injected through the center portion of the injection tube 5 1 0, the particles are incident almost perpendicularly on the transparent substrate 5 8 0, and the distance from the injection tube 5 10 side is shortened, the incident angle of the particles on the transparent substrate w 0 (The angle between the transparent substrate and the incident path of the injected particles) gradually decreases. In addition, among the injection particles emitted through the 50 side of the injection tube, many particles bounced out by the injection particles and emitted through the center. this

5152-5658-PF (Nl) .ptd Page 35 200420923 V. Description of the invention (30) Particles suffer loss of kinetic energy. Therefore, when the incident angle is increased (that is, when the distance between the emission particles and the injection tube 510 is increased), the transparent substrate 58: the particle impact also increases. Therefore, the average depth of the grooves varies according to different impacts. In view of this, even when the injection tube 5m of the third embodiment is used, the above-mentioned groove distribution map required by the present invention can be achieved due to the characteristics of the injection amount of the injection particles and the angle of incidence. Meanwhile, the thickness adjustment of the pipeline of the injection tube 510 can be obtained in many ways. One method is to adjust the thickness of the outlet 51 of the injection tube 51. As shown in FIGS. 22 to 25, 'a support rod 516 is provided around the outlet 510, and the feeding motors 5 14a to 5 14c are provided on this support rod 516, and the axis of each motor is connected to a target on one side or On both sides. By operating the servo motors 5 14a to 514c, the thickness of the outlet 51a can be increased or decreased to obtain the desired shape. In another method for adjusting the thickness of the outlet 51 of the injection tube 510, the thickness of the outlet 51 of the injection tube 510 is not large, and the catheter adjusting mechanism and 515b are provided inside the injection tube 510. This element makes the injection shape required shape. i U s green Figures 26c to 26e are A_A, tangent lines along the injection tube 51 〇. Fig. 26c shows when the two-catheter adjustment member 515a is provided inside the injection tube. The center of the catheter adjusting member 515a is thin, and its thickness is increased by 1 in the lateral direction. The cross-sectional shape of the injection tube 510 is medium: n I, and its thickness decreases in the lateral direction. When the catheter adjustment 515a is disposed on the inner wall of the injection tube 510, FIG. 26d is a cross-sectional view of the injection 510. When the catheter adjustment member is located within the injection tube 510, 200420923 V. Description of the invention (31) Part 'The central age of this catheter adjustment member reads less. /, Brother 6e is a cross-sectional view of the injection tube 510. A window π511 for inspecting the components of the injection tube 51 can be formed in the injection tube 51. M evil or 疋 U catheter adjustment This particle injection device 5 9 0 is preferably installed in the cavity: work = neat. The cavity 5 70 is placed in the conveying device: sending: holding a substantially cubic space surrounded by a side wall and a top surface. The body 5 70 is provided with the above-mentioned particle injection device 59. The cavity 570: η: opened, exposed to the transparent substrate to cause the small particles to be freely 'each down' and dust to collide with the transparent substrate 580. When the fine particles collide with the transparent substrate 58 0, more = cavity = 70. Therefore, a proper dust removal method is needed. To this end, it is better to install a dust removal device 56o, and then rotate 564 'through a tube 562 connected to the cavity 57o, suck the air through the internal filter (not shown in the figure), and move the body to The process is automated.
