The present invention is to develop a technique for the configuration and method for changing the function and performance of the light guide plate mounted inside the monitor in order to increase the brightness and clarity of the image and the characters appearing on the screen in the LCD monitor.

In the LCD monitor, the light transmitted from the built-in fluorescent lamp passes through the light guide plate, the prism, or the light diffusing film and reaches the screen of the LCD panel. As a result, we will develop a technology that enables new light diffusion and light multiplication.

The conventional technology for this is printed by applying a fluorescent material coating on the surface of the transparent acrylic plate in the shape of a mother scale to use the light guide plate. This application method does not exist in the refraction and diffusion elements of the light of the acrylic plate, but only the light diffusing effect of the fluorescent material coated on the surface and the light refraction effect by the space of the lattice spacing of the grid is transmitted through the monitor screen It is a structure that has a limit of light diffusion and transpiration effect.

In order to amplify the transmission of light and diffusion of light mounted inside the monitor, the main contents of the present invention include a conventional light guide plate of a fluorescent paint printing method using a V-shaped cross section or a U-shaped curved shape (V-shaped cross-section processing is a right angle). It is a task to develop a material of a light guide plate composed of a square pyramid shape (45) generated when processing in the direction. As a means for diffusing or increasing the light of a fluorescent lamp in a light guide plate of the same standard, the surface of the light guide plate is V-shaped or U-shaped (V-shaped). It is processed into a square pyramid shape (45) generated when processing the cross-section processing at right angles) to increase the transmission area of lamp light and increase the number of cross-sections to increase the amount of light refraction. We want to develop a light guide plate that allows light to be sent to the screen to increase the image quality and sharpness of characters.

The technical problem of the present invention relates to the development of a light guide plate for increasing the amount of light of the lamp transmitted through the LCD panel and increasing or evenly distributing the light to the image of the image projected on the LCD screen of the monitor. To improve performance and structure. The technical problem to be invented is a description of the function of the light guide plate 31 and its manufacturing method.

The transmission method of light installed inside the monitor increases the light generated from the light lamp and diffuses it. It is a technical problem of the present invention to increase the light diffusion performance.

In order to achieve this purpose, the performance of the light guide plate 31 which is combined inside the monitor is improved. Accordingly, the elements of the technology development are as follows.

First, the function of the light guide plate.

The transparent acrylic plate-shaped material, which is the material of the light guide plate used for the monitor, is processed to maintain a flat surface, and the surface of the transparent acrylic flat plate having a constant thickness is formed in a V shape (19) or a U shape (20) (V) at a height and an interval required by the user. The light guide plate 31 is processed into a square pyramid shape (45) generated when the cross-section machining is performed at right angles, and the center of the fluorescent lamp 37 and the side surface of the light guide plate 31 are fixed to be aligned in the fluorescent lamp 37. When the transmitted light is transmitted to the material of the light guide plate 31, the light guide plate 19 having a V-shaped processing surface processed on the surface of the light guide plate or U-shaped (square pyramid shape 45 generated when the V-shaped cross-section machining is processed at right angles) A) the cross section of the light guide plate 20 having the processed surface, i.e., the cross section 40 and b) the diffusion due to the transmission of the respective light to the cross section 41) a) cross section reflected light diffusion line 42 and b) cross section Light is diffused or increased as shown in the reflected light diffusion diagram 43 It is to get the effect. The light is brightened by being diffused or refracted by each of the V-shaped cross sections or by the U-shaped curved surface (including the square pyramid shape 45 generated when the V-shaped cross section is processed at right angles). Is made by

The light thus produced passes through the light diffusion film 32 and the prisms 33 and 34 to be projected onto the LCD panel screen 36.

At this time, the light reaching the LCD panel 36 repeats the diffusion and refraction indefinitely so that it is a very bright and very uniform projection light, which can greatly improve the image quality and clarity of the image.

Second, on the manufacturing method of the light guide plate

The transparent acrylic plate, which is the material of the light guide plate, determines the outer dimension according to the monitor specification and performs the plane processing, and then determines the surface processing depth (17) and the surface processing area (18) to be used, and has a light guide plate having a V-shaped surface (19). ) Or a U-shaped processing surface, the light guide plate 30 is produced by a machining method by cutting, or by a molding process by rolling and extrusion.

① Machining by cutting method is V-shape or U-shape cutting edge according to the shape of cutting edge of light guide plate 31 to determine the cutting amount and cutting width on the surface of transparent acrylic sheet and arrange the cutting edge <Fig. 5 (21), (22), (23) and (24) in order to process the entire processing area in one stroke, and the processing cross sections of the light guide plate cutting edges 21, 22, 23, and 24 in sequence. The cutting edge is to be constructed so that it can be divided into cutting methods.

② As described above, the processing of the light guide plate material processed can be manufactured by dividing it into one unit unit according to the production method and a case of continuously processing a large number of units.

As described in the technical problem, in the combination of the LCD panel mounted on the monitor, the light guide plate 31 is a reflective light pad 30 which is a monitor component among the components for transmitting the light transmitted from the fluorescent lamp to the screen of the LCD panel. It is composed of the light diffusion film 32, 35 and the prism 33, 34, and when the light is transmitted from the double fluorescent lamp 37, the light is absorbed by the light guide plate 31 and transmitted through the light guide plate 31. The light is refracted by the a) cross-section 40 and b) the cross-section 41 processed on the surface of the light guide plate to a) the diffusion effect of light having the a) cross-sectional reflected light diffusion diagram 42 and b) the cross-sectional diffusion diagram 43, respectively. You get The light obtained in this process is collected and transmitted in the projection direction 44 of the light to reach the LCD panel screen 36. The continuous generation of light diffusion and refraction results in an infinite number of refraction curves of light, thereby obtaining a light projection effect of better performance than a conventional fluorescent paint printed light guide plate.

As a result of the performance of such a light guide plate, bright image quality and uniformity of light distribution are upgraded to maintain the sharpness of a character.

As described above, the configuration and function thereof will be described as follows.

The same amount of light of the fluorescent lamp 37 is transmitted to the end face of the light guide plate, and the light is transmitted and refracted by the same movement by the light guide plate front surface. Therefore, the image screen becomes brighter due to the light diffusion effect, and light transmitted through a large number of refractive cross-sections is synthesized to form an image of light with a uniform distribution, thereby obtaining a clearer monitor screen.

As described above, the technical effect expected by the present invention is to increase the brightness of the LCD panel screen by the light diffusion of the light guide plate, thereby improving the image quality of the projected image and spreading the image and characters at the side angle of the screen. As it can be removed, it contributes to the advanced LCD screen.

In addition, in demanding high-quality performance, the performance improvement due to the change of the original technology due to the improvement of functionality by the structure of the light guide plate without the improvement by optical or electronic control has a new technical value of the LCD panel.
