New Description: [New Technology Field] This creation is about a light-weight group, especially a backlight module made by combining multiple light-emitting units. [Prior Art] According to the advancement of the high-tech industry, traditional display products made of image tubes (such as image tube TVs, image tube monitors, etc.) have gradually been adopted by liquid crystal displays (Liquid Crystal Display, referred to as The LCD panel is replaced by a panel manufacturer, which is mainly composed of a glass panel and a color filter, and is filled with a liquid crystal material, and a backlight module and a driver IC. And the control circuit board and other components are connected so that products with LCD panels (such as TVs, monitors, notebook computers, etc.) have the following advantages: The LCD products are smaller in size than conventional images. The tube products are light and short, so that users do not need to plan too much space when laying out the layout environment, so as to place these products, which makes the products more space-saving, and thus effectively increase the space availability. . 2. The weight of these LCD products is much lighter than traditional image tube products, making it easy for users to move these LCD products. 3. The surface changes of these LCD products are stable, and users are less likely to hurt their eyes when they watch for a long time. 4. The power consumption of these LCD products is also lower than that of traditional image tube products. In addition, since the price of LCD panels is becoming cheaper, in recent years, it has been gradually loved by individuals and businesses, and is widely used in daily life M328588 and work. Generally speaking, the liquid crystal itself is not illuminating material, so the LCD panel mainly supplies the light source with sufficient brightness and uniform distribution according to the back light module, so that the image can be normally displayed. Traditionally, the backlight module uses an edge lighting structure, and its structure mainly includes a light 卯洫 plate, a reflector, a prism, and the like, as shown in FIG. 1 . A backlight module 1 of a conventional side-light structure, the backlight module 1 includes a light guide plate 12, and a side of the light guide plate 12 is provided with an arc-shaped opening and a light reflection sheet toward the light guide plate 12; 3, and in the gap formed between the side of the light guide plate 12 and the light reflecting sheet 13, a cold cathode lamp tube 10 is disposed, and a bottom surface of the light guide plate 12 is further provided with a reflecting plate 14, so that when the cold When the cathode lamp 1 〇 emits the light source, the light source can directly enter the light guide plate 12 or be reflected by the light reflection sheet 13 into the light guide plate 12, and the light source is refracted through the light guide plate 12, and the reflection plate After the reflection of 14 , it can be uniformly projected from the top surface of the light guide plate 12 to make the LCD panel product display the image, which is clearly presented by the county side, and avoids the user seeing on the display panel. The shape of the tube. However, such a conventional edge-lit backlight module has a cold cathode lamp 10 placed on the side of the light guide plate 12, so that it is not only easy for the user to use the display surface _, and side leakage occurs. That is, the brightness of the side of the display panel is high, and if the light guide plate 12 used for the backlight is thinner or larger in size, then the light guide plate 12 is farther away from the cold cathode lamp tube, and only By the reflection of the back test 14, the vehicle is obtained, resulting in the smaller the track rate of the light guide plate 6 M328588 12 to the light source, so that the light module needs to consume the brightness of the power supply panel of the hometown, and The conventional edge-lit backlight module 1 mainly uses a body-shaped light guide plate, so that when a panel manufacturer wants to produce display panels of different sizes, it is necessary to prepare a plurality of light guide plates with a face panel. It is necessary to produce and stock many different sizes of county boards, in order to meet the different panel requirements of different sizes, and the "A size of the light guide board has caused many problems and difficulties in production, transportation and storage, resulting in the production cost of the display panel. High• Therefore, how to design a low-cost light guide plate and to manufacture backlight modules of various sizes is an important issue that panel manufacturers are striving to study and hope to achieve. [New content] In view of the shortcomings of the above-mentioned backlight module, the creator has been working hard for a long time to study and strip, and finally to provide a material complement-(4) optical module 'and its light-guiding block'. By combining a plurality of light-guiding blocks and illuminating elements to form a display panel of various sizes, it is possible to achieve an effective reduction in production cost without using an integrally formed large-sized light guide plate as a backlight module. The purpose. One of the purposes of the present invention is to design a backlight module and a light guiding block thereof, the backlight module being composed of at least one light emitting unit, wherein the light emitting units are horizontally side by side and adjacent to each other. The two sides of the light-emitting unit are abutted against each other, and the light-emitting unit comprises two light-guiding blocks and a light-emitting member (such as a cold cathode lamp, a light-emitting diode, etc.), wherein the light guide The block system has a rectangular parallelepiped permeable material (such as · · Acrylic, Polyvinyl chloride 7 M328588 ene, referred to as PVC and polycarbonate, referred to as PC...etc.), the cross section of the light guiding block is trapezoidal And the top surface width is greater than the bottom surface width, and the two sides of the light guiding block body are respectively a first inclined surface and a second inclined surface, and the bottom surface of the light guiding block body and the first inclined surface are respectively covered with a reflective a sheet body (such as a reflective tape), and a top surface of the two light guiding blocks adjacent to one side of the second inclined surface and abutting each other horizontally, so that a space is formed between the two light guiding blocks a gap for the light emitting member to be disposed in the gap formed to enable the hair The light emitted by the device can be uniformly projected onto the top surface of the two light guiding blocks through the refraction of the two light guiding blocks and the reflection through the reflecting sheets, so that the panel manufacturer can By combining a plurality of light-emitting units to form backlight modules of various sizes, and manufacturing display panels of various sizes, a large-sized light guide plate without integral molding is used as an optical module to achieve an effective reduction in production cost. purpose. Another object of the present invention is to provide a high-brightness backlight mode, wherein the light-emitting unit is disposed between the two light-guiding blocks, so that the light-emitting member can directly pass light through the light-guiding block body, and The bottom surface of the light guiding block body and the first inclined surface are respectively covered with a reflective sheet body, so that the light not directly refracted to the top surface is reflected to the top surface, so that the light guiding blocks of the backlight module are all Corresponding to each of the illuminating members directly providing a light source, instead of a thin light guide plate like a conventional edge-lit backlight module, the light source provided by the side of the light guide plate provides a light source, resulting in low light utilization rate The shortcomings of the present invention are that the light-emitting units of the present invention are combined into a thin group, which is far superior to the light-emitting backlight module, and can provide a more sufficient and uniform light source. For the purpose of the purpose of this creation, technical characteristics and its work, we will do more with a little more than 5 tolerance and understanding.
