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.

Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a light guide plate with a small groove I ^, forming a gradient pattern on the surface: off :: with micro: = uniformity, and Does not require the use of -light "to enhance the liquid crystal display (LCD) panel or plastic film for advertising. ^ Requires backlighting to achieve the display function; ^^^ 2 light elements are one of the main elements, and the conversion light: learn light source Mi Chengma + surface light according to the position of the optical light source '一 backlight element # has been 掊 ★ 方 沬 μ · .. The method of forming the nine elements can be divided into the dlrect-type method (dlrect-type method) Or a light guide plate method 'light, guldlng panei meth〇d). The direct method directly sets 2 light sources under the light emitting surface; ^ to ensure the emission of planar light. The light plate method is to place an optical light source on one of the light guide plates Side, 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 the plane light is radiated. The present invention applies the above-mentioned light guide plate method. Known manufacturing technology of light guide plates for LCD backlight elements includes dots. Pattern printing Dot pattern printing method, using silk printing technology and V-cut method, using a mechanical tool. In silk printing technology, dots are formed on the bottom surface of the light guide plate using silk printing technology, and tiny glass beads are placed in the dots. The light is scattered on the surface of the glass beads, and the scattered light passes through the upper surface of the light guide plate.

In addition, the 'printing process is quite complicated, ^ during the printing process' there will be many defects. In the v_cut method, A machine = a V-shaped groove is directly formed on a transparent acrylic resin "Valley Acrylic = Acryi ^ resin" substrate, so that the light incident at one end of the panel is reflected on the square surface of the light guide plate. However, in the light 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 front surface of the light guide plate, so that the reflection pattern is displayed on the light guide plate. In other words, because the size of the reflection pattern reflected by the dots or V-grooves can be seen by the naked eye, it is called " light spot " formed on the front surface of the light guide plate. Among the light spots, the, and the part are partially mixed with the dark part or At the same time there is m removal wire, such a light guide plate is not suitable as a backlight element. In order to remove the light spot ', a diffuser plate "丨 ^ to 丨 ⑽" "^ ^ a diffuser plate plus a prism sheet is connected to the front surface of the light guide plate. If a diffuser plate is used, it can be dispersed appropriately The amount of light improves the uniformity of brightness. However, the light transmission coefficient of a diffuser is usually about 6 8%. 'Using a diffuser or other similar side effects that cause light loss, the optical efficiency will decrease, and the brightness of the backlight will vary with In order to improve the optical efficiency, a light guide plate is needed, and the light guide plate does not need: a diffusion plate or the like.

[Embodiment] The following describes the details of each aspect disclosed in the present invention with specific examples. As shown in Figs. 1a and 1b, on one surface of the light guide plate according to the present invention (referred to herein as the bottom surface), minute grooves form a step pattern thereon. The distribution of the grooves on the light guide plate varies depending on the method of incident light. In the light guide plate 30 of the ^ la figure, the two sides of the light guide plate 3Q and the incident light incident plane, and in the light guide plate 35 of FIG. Lb, one of the sides of the light guide plate 35 is the light 2 surface. The light guide plates shown in Figs. 13 and 11) are used to help understand the concept of the present month. Also, according to the present invention, it is necessary to pay attention to the shape of the light guide plate in accordance with the present invention. In a real light guide plate (shown as / Λ sheet), the recesses on the bottom surface of the light guide plate 40 are invisible to the naked eye. Due to A, gaze at a part where all grooves are formed (all surfaces' except for the area measured from each side) is fuzzy and translucent.疋 Wide through manufacturing and measurement phase.

When the light source is turned on, the light = the condition of the groove shape above. When it is farther away from the inside of the light guide. : The principle of guiding can also be applied. The concave pattern on the bottom surface of the light guide plate becomes brighter on the bottom surface. The characteristics of the groove on the back must meet the following conditions. When Tatian grooves are formed on the bottom surface of the light guide plate, they must be formed; a small number of groove densities and average depths are: flat =: at the same time, 'when gradually away from the light source', Beijing is especially good; increase, so although the light Strongly ^, the i: t ΐ line is reflected on the bottom surface of the light guide plate. Also in: A condition of the Erguang Group stipulates that as the distance from the light source (tube light) increases, the groove density, average depth, and average size 2 on the bit :: ίϊΐ will increase at the same time. When the distance from the light source increases, the groove density, average :::, Γ, and average size will increase and then decrease, and light spots will occur. In the description of the conventional technology, the reason why the light guide plate with a small groove "= cannot be successful is because χ? 八 has not been issued yet. (2) A manufacturing method that satisfies the above conditions. The second condition is that the size of the groove on the bottom surface of the light guide plate must be so small that it cannot be seen with the naked eye. This is because if the groove size is not so small, 'when looking at an area', the bright and dark places will mix and co-exist-so the light spot will be seen. Light spots will affect the light guide plate, which does not use a diffuser on the backlight of liquid crystal displays or transparent films for advertising.

Description of the invention (10) -------- Figure 2 shows the production of the light guide plate 4 with a digital camera to meet the conditions of the above groove profile . (In the second figure, the light guide plate 40 is transparent, and the portion with the groove on it is semi-transparent ^, but the true shape of the light guide plate 40 must be taken into account and Not fully shown because a blue piece of paper was placed under the light guide when shooting). As shown in the light guide plate in the first figure, the light guide plate 40 in the second figure has a fluorescent lamp, and here is a light source, which is installed on the left and right. In order to find the characteristics of the groove profile on the bottom surface of the positive light guide plate 40, the inventor sampled seven different samples (42a to 42g), each of which was appropriately sized. Sampling each preset range of a straight line starting from arrow A, and using multiple methods. First, the surface of each sample was taken with a scanning electron microscope. Figures 3a to 3g show seven different samples (42a to 42g). In this picture, it can be seen that the grooves are bright, and the dark parts indicate areas where ^ is not formed. In addition, it can be seen that the density and size of the groove from the photo 3 & to the groove gradually decrease, that is, from the center of the light guide plate 40 to the left. For more detailed observation, take the 3D surface shape of the preset part and take it to the 4g figure. From these pictures, from inch to inch, from the left of the light guide to Canada. Using light interference method to take down the seven samples' shooting results are shown in Figure 4a. It can be determined that in addition to the groove density and the depth of the ruler's groove, the depth of the grooves will also gradually increase. In Figures 5a to 5g, it is shown on the seven samples. 8 the amount of public love

It can be seen from some of the data that the left to the center of the light guide plate 40 is concave; the mean derivative of Nfe I ^ gradually increases, and these measurements also conform to the change pattern of the average depth of m '. Although the values of the 5th and 6th samples are similar: It can be regarded as an exception to the characteristics of a sandblasting process. From the probability of π = 11, it can be determined that as the distance from the light source becomes more and more, and the value gradually increases at a, it conforms to the above-mentioned change pattern of the average depth of the groove. Fig. 6 is a pattern of a preferred embodiment of a backlight element, and the light guide plate of the present invention is applied to the u backlight film. In the backlight element, when a power supply is provided, a cold cathode fluorescent lamp 10 and the light guide plate 30 or the most J side of the light guide plate are parallel to each other, and a reflective cap 12 surrounds the fluorescent lamp and reflects the fluorescent lamp 10 The generated 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 small groove is formed like the above pattern. On the bottom surface 32 and not installed The side of the fluorescent lamp 10, the bottom reflecting plate 20 and the side reflecting plate 22 are connected to each other, 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 Connected. This: so

1223107 V. Description of the invention (12) Some objects are composed of a frame by a frame 24. 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 front 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 has a relative advantage over the use of a diffusion sheet. Advertising films are made of transparent films, or 疋 are made of 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 uniformly diffused light in the light guide plate can be obtained, so another diffusion sheet is not required. Figure 7 is a coefficient-bit photograph. The light guide plate 50 produced by the light guide plate 4 Q of the present invention and the dot pattern 2 t of the conventional technique is placed on the camera by using a digital camera and an identical fluorescent lamp 1 G '. . In the conventional technology of dot pattern printing method, the size of the dot pattern can be seen with the naked eye, so it is necessary to use a diffuser, or you will see the dot pattern.

Meanwhile, in the present invention, even if a diffusion sheet is not used on the front end surface, the light guide plate 40 can still provide natural and uniform diffused light. Fig. 8 is a digital photograph. A transparent film 60a is placed on the light guide plates 40 and 50 in Fig. 7 by using a digital camera. As shown in the photo, in the light guide, 50, and 50 produced by the dot pattern printing method using the conventional technology, even if the transparent film is placed on the light guide plate 50, the dot pattern can still be seen with ^ eyes. Therefore, the light guide plate 50 is not suitable for backlighting using a transparent film made of advertising film. Figure 9 of the Institute of Pancreas is a digital photo. By using a digital camera, a bright advertising film 60b and a film with light diffusion function are combined, and then placed on the light guide plates 40 and 50 in Figure 7. Shoot it down. The photo also shows that the light guide plate 40 of the present invention is brighter and clearer than the dot pattern printing method, and shows that the guide of the present invention is based on the doctrine of the dot pattern printing method. ^ ^ ^ ^ ^ ^ ^ Produces a shell degree of 50 for the pilot plate.

Because the micro-particles of the switch cup% OOη are in an open state, the penetration of the content member 2000 g _〇χ from ^ = through the aperture 2000i to the connection and 2_, in the interval, injection of particles Because: the opening 2_ M of the penetration hole 2000 × M ^ shooter pulls down like a free fall. The use of a pressurized fluid, such as ^ 9ηπ, i-roller or water, passes through the pressurized fluid supply 200 200: shot to the nozzle 200a, the low-pressure ring 22 produced by high-speed spray The next &lt; injection particles are pulled and passed through the particle supply tube 200 f and mixed with the pressurized fluid to inject the injection particles ^ ^ and then injected through the mouth 200a to the outside 0 Special 颗粒 The particle injection device of the present invention 2 0 0 The time is to keep-fix the amount of injection particles, and the amount of injection particles in a unit time can be adjusted by the size of the aperture 200 i. For a traditional injection device, this is the relative of the injection device 200 of the present invention. advantage. In terms of time, the reason why a fixed amount of the injection particles through the nozzle 2000a can be maintained is that when the injection particles flow to the 200 g penetration hole 2000x of the connecting member, the injection particles will fall vertically, Like an hourglass. The reason why the injection particles can fall freely is because the openings of 200h and 20 Oh are formed on the connecting member 2000g. Due to the characteristics of the fine particles, the fine particles do not have good fluidity. Therefore, an injection device using a vacuum inhalation method according to BernoulU, s theorem has been widely used in the conventional technology. If a component is not provided on the path for supplying the injection particles, the component is used to allow external air to flow in to avoid the generation of a high vacuum. When a pressurized fluid flows through the nozzle 20 0a at a high speed, a low-pressure environment will be generated. It's a vacuum. except

5152-5658-PF (Nl) .ptd Page 23 1223107 V. Description of the invention (18) The penetration force of the pressure structure 2 000g generated by the air is applied to the whole, then, when it strikes the wall or And change. In particular, the degree of pressurized fluid will change accordingly, so it will be averaged. In this way, the injected small particles form a groove. As a change, the supply path of the 200x through hole should be around the particle phase before the path. Because the amount of pressure changes with time, the density of the small particles depends on the amount or injection. Gradation pattern, in addition to the gravity, because the height of the particles injected into the container 200η will be even stronger. This powerful suction 'is from the aperture 200i to the nozzle 200a. The strong and powerful suction particles collide strongly, so the speed will change because the friction fluid passes through the pressurized fluid supply tube 2000d, so the change in the density of the nozzle 200a will cause the pressure of the supply path to change. The amount inhaled from the aperture 2 0 0 i becomes otherwise persistent. Therefore, if the jet velocity from the nozzle 2000a becomes uneven, it becomes difficult to be on the surface of the transparent substrate 140. However, in the present invention, if the openings 20Oh and 20O 'connected to the particle supply path are formed on the connecting member 2000g, even when the low-pressure environment generated by the high-speed ejection of the pressurized fluid, the air can be continuously Ground through the openings 20Oh and 20Oh from the outside for supply and replenishment. Therefore, the low-pressure environment is only formed at the openings 200h and 200h of the penetration hole 200χ. Below, the atmospheric pressure is still higher than the pressure in the traditional method, and especially at the openings 200h and 200h of the penetration hole 200x. In the upper range, no low atmospheric pressure was generated at all. Therefore, ‘forced inhalation of particles by pressure changes does not occur’, only particles that fall freely relying on gravity. After passing through the openings 20h and 20h ', the free-falling particles will be strongly pulled and injected from the nozzle 20a.

5152-5658-PF (Nl) .ptd Page 24 1223107 V. Description of the invention (19) If the free fall distance can be established, the injected particles will fall freely like the hourglass principle, so a particle supply tube can be provided. 0f A preset amount of particles that changes over time. Therefore, although the amount of the minute particles injected from the nozzle 200a changes in a short period of time, because the amount of pressurized fluid passing through the pressurized fluid supply pipe 200 d changes with time, it can be maintained A fixed amount of fine particles within a set time. Moreover, by adjusting the size of the aperture 200i, the &gt; main shot amount can be accurately controlled. Even if multiple nozzles are installed, the injection volume of each nozzle can be easily and accurately controlled. In addition, the controllability of injection volume and time consistency can improve the uniformity and reproducibility of product quality. Referring to FIGS. 11 to 13, arrange the nozzle devices 10a to 10d so that the injection direction and the conveying direction are perpendicular to each other, and when looking from below the front surface of the transparent substrate 140, the injection direction is directed toward the incident light surface at a set angle. To make a dilute acid base, the raw material of the plate can be used for injection. ^ (Zi rcon ia) is not limited to the dense particles of the upper plate material. And particles. Satisfy · "Ding Eryou is used without special restrictions on the particle size of silicon carbide (s, or diamond particle size and can be, preferably these conditions of raw materials, a transparent resin substrate, such as C and in the present invention The basic system can be fully used. Say 'can use carbonized I Lu (a 1 uminumi 1 icon carbide), hafnium oxide particles', but the types and types of particles that can be used', as long as the hardness of the particles is greater than the transparent base for effective formation Groove, you can use this kind of diamond particles with the most suitable particle type for injections with high uniform shape and size. Diamond

1223107 V. Description of the invention (20) The particles have good fluidity, so they can be smoothly supplied. Because of the impact of the particles during the supply of the particles to the nozzle, the size of the particles 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, the transparent substrate is cut into a desired size, and then it is placed on the transfer line of the transfer device 1000. By controlling the transfer device 100, the transparent substrate 140 is transferred at a preset speed. At this time, by operating the injection device 200, the particles can be injected obliquely onto the transparent substrate 140. At the same time, in order to reduce the darkening on the side of the light guide plate, commonly known as H-beam effect ’can be considered when particles are injected into the side of the transparent substrate 丨 4’! The transfer speed can be reduced, so more grooves are formed on the side. After the process of forming the groove is completed, the substrate is transferred to the process of cleaning, drying &amp; inspecting. 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 142b face each other, such as the light guide plate 30 shown in Figure ja. 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 conveyance. However, the other two nozzles 10c and 11d form grooves on the left half of the transparent substrate 140, 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 1223107 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 will also increase, and, in a unit time, from The number of particles injected by the first and third nozzles 110a and 110c is preferably larger than the number of particles injected from the second and fourth nozzles 丨 丨 b and 丨 丨 d. In another method, the injection pressures of the first and third nozzles 110a and 110 may be greater than the injection pressures of the second and fourth nozzles H0b. In addition, the above two types may be combined and applied Method, adjust the particle injection volume and nozzle injection pressure. The feed direction is tilted from the transparent base &gt; (7Γ will also reduce the depth and also from the number of nozzle wide grooves, and when the possibility is the contour, so as the guide After mounting each of the nozzles 110a to 110d at the bottom of the light plate, the injection direction will be straight and inclined toward the surface of the transparent substrate 140. If the angle of injection of the minute particles into the transparent substrate 140 will follow the plate The distance from 140 to the nozzle increases and decreases. Because (redundant / 2) a / 2)-0 2, the shadow of the small particles on the transparent substrate. Therefore, the size of the groove formed on the surface of the transparent substrate 14 will be It decreases as the distance from the nozzle 200a increases. Also, because the particles are flooded, the depression on a unit area of the transparent substrate 140, that is, the groove density, also decreases as the distance from the nozzle decreases. Mouth reduction In a small amount of time, the particles will collide with each other in the same place, plus. Therefore, the groove size increases and it becomes more complicated to combine with nearby grooves. The complexity of the groove surface profile will increase. The formation of this process makes it possible to obtain the contours of the grooves on the surface of the aforementioned part.

1223107 V. Description of the invention (22) &quot; 一 &quot; 1 Figures 16a to 16c show the process of forming a groove in the light guide plate. The light guide plate has an incident light surface U2b and two nozzles u0a, and 110b, As shown in the figure. If the size of the transparent substrate becomes small, only one nozzle is sufficient. The two nozzles U〇a, and u〇b can be arranged on the diagonal of the x-y plane, as shown in Fig. 16b, or arranged in a column "from the direction, as shown in Fig. 16c" When the nozzles are arranged as shown in Figure 16c, in order to obtain the groove gradient pattern, it is best to be the second nozzle. Note that the pressure and injection volume are less than the injection pressure and Injection 1. 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 nozzles 110a 'and 110b. Next, the manufacturing device and the The second and preferred embodiment of the process of the present invention 丨 According to the present invention, the 17th circle shows a second preferred embodiment of the structure of a light guide plate manufacturing apparatus. The second embodiment uses a vertical and expansion method, This method uses a built-in nozzle. When compared with the manufacturing device in Figures 11 to 13 above, the embodiment of the device is not different in terms of the structure of the conveying device 100, with only one basic difference, namely the injection direction and Not / toward 'transparent substrate 14 〇The surface is inclined, but it is vertical. A plurality of nozzles 31〇3 to 310 丨 are arranged in a direction perpendicular to the conveying direction of the j conveying line on the conveying bar 128. The nozzles 31〇a to 31〇1 are below the surface of the transparent substrate, And the direction of the spray is perpendicular to the surface of the transparent substrate. In addition to this, when the distance increases from the incident light surface, the groove distribution and size $ increase. The nozzle is installed so that when the distance increases from the incident light surface, The interval will be reduced. Figure 17 shows a light guide plate

1223107 V. Description of the invention (23) &quot; An example of one 'The two sides of the light guide plate are incident light surfaces, and also show that the interval D2 between the spray 310h and 310i is greater than the interval Dl between the nozzles 31〇d and 310e. Therefore, when For nozzles, different injection volumes and particle pressures can be applied. In order to achieve the groove wheel temple 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 covering the corresponding surface ^: ^ mouth will also 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 gradual pattern of uniform grooves, 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 丨 2 2, the horizontal adjustment bar 1 2 2 is fixed on an LM guide 350, and a servo motor 360 is connected to the LM guide bow 350. Due to the structure of A, the servo motor 3_guide 350 swings in one direction (right of Jd) (right side of Jd) is perpendicular to the transmission direction of the transparent substrate 140. Therefore, the nozzle can inject the particles uniformly on the entire surface of the transparent substrate and does not generate a blank space. Fig. 18 shows the structure of a particle injection device 300, which can be applied to a vertical injection method. The particle injection device 300 is different from the particle injection in FIG. 18 and is set to 200. The difference is that the nozzle 31 is injected from below. More specifically, the 'particle supply hole 2000e' is connected to the back of the nozzle body 300c, and the pressurized fluid supply hole 300d is bent about 90 degrees and connected to the side of the nozzle body 300c. Except for this difference, other characteristics like that the particles are supplied to the nozzle 3 1 0 by free fall are the same as the particle injection device in FIG. 4.

1223107 V. Description of the invention (24) At the same time, using an acrylic-based resin substrate having a size of 309 mm X 236 mm, the present inventor implemented the manufacturing apparatus using the oblique injection method in Figs. 11 to 14 The process of groove formation. The state of the manufacturing process is described in the following Table 2. The transmission speed of the acryl-based resin substrate is 900 mm / min. The angle between the nozzle angle and the surface is 7 degrees. The nozzle pressure is 6 kgf / cm2. Injecting diamond particles (# 150: 0 ~ i5〇em). The injection volume of particles is 0.4 1 / min. Fig. 19 is a photo taken by using a microscope at three places on the surface of the light guide plate 30 (30x, 30y, 30z; as shown in Fig. 5a). The light guide plate is manufactured by treating the acryl-based resin substrate by the oblique injection method. As shown in the three local distribution photos, in the area 3 5χ, the groove distribution has 54 grooves per square millimeter, and the area 3 5χ is close to the incident light surface 30a, and in the internal areas 35y and 35ζ, The number of grooves will gradually increase to 120 and 180, respectively. Also, it can be determined that as the distance from the incident light surface 30 increases, the size of the groove and the depth of the groove also gradually increase. If the light is incident on the light guide plate, the light immunity will be evenly guided to the entire light guide plate. Fig. 20 shows a result, in which light is incident on a light guide plate incident surface, surfaces 400a and 400b, and the result of measuring the surface truth of the light guide plate is obtained. The brightness range is between the maximum of 7600 lx and the minimum of 68〇u ~

1223107 V. Explanation of the invention (25) The brightness error is about 10%. Figure 21a is the brightness distribution of distances 400a and 400b from the incident light surface. Although the center looks a bit dark, the error is negligible. In addition, figures 21b to 21d show the size, depth, and number of grooves according to the distances from the incident light surfaces 400a and 400b. These figures also determine the characteristics of the groove profile, that is, when the distance from the incident light surface 400a and 400b increases and the groove distribution density also increases, the average size and depth of the groove also increases. Although a flat light guide plate has been used as an example so far, the present invention is not limited to a flat surface, but can be applied to a wedge-shaped light guide plate. Next, a third preferred embodiment of the present invention will be explained. 22, 23, and 24 are a side sectional view, a front sectional view, and a plan view of a structure of a light guide plate manufacturing apparatus 500 according to a third preferred embodiment of the present invention. ^ The third embodiment uses a vertical blasting method, which uses a thin funnel tube, and the light guide plate manufacturing device 500 includes a particle injection device 5900 and a conveying device 600. The transparent substrate 580 is placed on the transfer device 600, and the transfer device 600 transfers the transparent substrate 580 in one direction. The transmitting device 60 0 may be a brigade. In addition, a pair of guides 600f and 6008 are spaced a preset range ^ p n W rows'-a conveyor 600k is mounted on the outer surface of the guide rail. In one of the 600g fan rails * mountain-μ ^ ^ R * &amp; women's motor 60 0a and gears 600b, 600c, 600a expansion gears connected to the main shaft of the motor 600a and On the motor, the value of the force is transmitted to the 600k and 600k conveyor belts 600k and 600k, respectively. By crossing the two rails vertically

1223107 V. Description of the invention (26) The sides of 600 f and 600 g, the guide bars 60001 and 6001 hold the guide rails 600 and 610, so the two guide rails maintain a preset At the same time, if the external force is applied to the guide rail, the guide bar will slide and support the guide rail, so the distance between the guide rails 600f and 6002 can be adjusted accurately. In addition, there are motors 600 i-1 and 600i-2 and gear shafts 60011 and 600 installed to adjust the distance between the rails 600f and 60g. The gear shaft 60 is called to extend toward the axis of the motor 6 0 i-2, and the gear is combined with the guide rail. At the same time, the gear shaft 6 0 h is extended to the axis of the motor 6 0i-1 and the gear and Guide 600 f combined. If the gear shafts 60 ° and 600 ° are rotated by the drive motors 600 i-1 and 600 i-2, the rails 60 0 f and 60 0 g can be pushed or pulled, so the two guide rails can be adjusted. The distance between. It is best to carefully design the distance between the two guide rails 600 f and 600 g to accommodate the largest size transparent substrate. Therefore, the transparent substrate 5 80 is placed on a conveyor belt 60 ", which is wound around the outer surfaces of the guide rails 60 0f and 60 0g. In order to avoid the transparent substrate 580 from bending due to the strong injection pressure of the small particles, first A support plate 582 that can withstand the maximum injection pressure and does not bend is placed on the transfer bar 600k, and then a transparent substrate 58 () is placed on the support plate 582. ', In order to form a transparent substrate 580 The desired groove pattern can provide a function to control the transfer speed. To this end, a control unit 61 can automatically control the transfer speed. In addition, a suitable position on the transfer line, such as the injection tube 510 Front or back, install sensors 584a and 584b to detect the channel of the transparent substrate 580. The control unit uses the detection signals of the sensors 5 8 4 a and 5 8 4 b to control the transmission speed.

1223107 V. Description of the invention (27) In order to fully automate the manufacturing process of the light guide plate, only the function of 1G is used. That is, in the present invention, it is necessary to extend the control to use a servo motor, and the 'control unit 61〇 has a device: :: system: the user sets the operating conditions to automatically control the word server :::: data connection Next, we will explain the particle injection device 59; Γ: the second drop from the second drop freely into μ. With two particles, the state of 540 is free, and the soil supply time of small particles is always maintained ... This is the same as the previous two two = two hanging. Preferably, the switch control unit 544 is mounted on the outlet 542. : Report ^ In \ can release small particles by opening the outlet. ON = Early TC544 can use a solenoid valve. Also, for easier and smooth placement in the container 540, it is preferable to mount the vibrator 540 used for the vibration + dynamic state 540 at an appropriate position on the outer wall of the container 540. Tiny particles falling freely from the container can be uniformly mixed with high-speed air. To this end, a mixing conveying unit uses a device to manufacture high-speed air and discharge mixed particles from an outlet, sucks particles that fall from the inlet, mixes the particles in high-speed air, and then mixes the particles from the outlet discharge. The mixed transfer unit can use a hair dryer. The figure shows a structure having two hair dryers 52 and 53 () connected to each other. A female hair dryer 5 2 0 and 5 3 0 has an approximately cubic internal space and inlets 522 and 532 and outlets 524 and 534. Motors 526 and 536 are installed

1223107 V. Description of the invention (28) Inside the part space 'and a motor is installed outside the cubic space. The central axis of the motor is connected to the rotating wheels 526 and 536, and the rotating wheels 526 and 536 can rotate at high speed. By rotating the motors 528 and 538, the rotating wheels 5 26 and 536 can be rotated at a high speed. Therefore, the small particles that fall freely near the first blower 52o inlet 522 will be drawn into the inlet, and then the small particles will It will collide with the rotating wheel 526 and mix in the air flowing at high speed, and finally discharge from the right outlet 524. After mixing with air, the micro :, particles: will be discharged from the outlet 524, and then will be discharged by the second blower 53 billion plus: exit 534. In addition to the structure shown in the figure, the construction mix t: Γ can be used: one, three, or a plurality of hair dryers. It is also not shown that an air pressurizing device 'like a compressor' is connected to the guide surface by using a duct with an opening to form an opening, and supplies a South-speed pressurized air-guided transmission unit. The &amp; guide to &amp; exit can constitute a mix. Although the nozzle has been used in the previous two embodiments, the Q series is about too small particles to be ejected from the mixed palladium. Injection tube 51. With two early states, the port W is in phase with the exit 534 of the transmission unit. The internal cross-sectional shape of the entrance is shown in the direction toward the exit and: The base lake passes through from below the exit 510a; the transparent particles will be associated with the high-speed flowing air, and will be slightly emitted. Injected by the mixing conveying unit # 官 510 以南 速 The shape of the injection tube 51 &quot;

1223107 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 10 can be determined by using a cloth pattern as the groove formed on the transparent substrate 58. In order to improve the production efficiency, it is best to pass the transparent substrate 580 once from below the injection tube 5 to form the desired groove. Also, it is preferable that the exit width of the injection tube 510 is not smaller than the width of the transparent substrate 580. It is preferable that the exit of the injection tube 510 covers the entire width of the transparent substrate 58, and the transparent substrate 580 passes under the injection tube 510. At this time, the groove distribution of the transparent substrate 580 is changed according to the position on the surface of the transparent substrate 58Q. Basically, the groove distribution density is increased as the distance increases from the position of the light source. Because the density of the groove distribution is proportional to the number of particles passing through the injection tube in a unit time, the groove distribution can be adjusted by changing the thickness of the injection tube 510 in the width direction. &amp; transparent substrate 580; proud, w injection in areas with high distribution density and ulcers, you can spread the grooves to itching ^ / Sheguan 51 〇 increase the thickness, and the groove knife cloth company, The thickness of the injection tube 510 decreases in the lower f region. Introducing sand blasting, you can get the distribution map of Cao in the 5110 of the present invention. In other words, when the particles are injected through the injection tube, the transparent substrate and the injection steps are filled with many particles. Among the injection particles on the side of the main injection tube 510, the injection is rebounded by the injection particles and ejected through the center. this
