Description of the invention (1) Field of the invention: The present invention provides a liquid crystal display, especially a liquid crystal display with a reflection plate as a frame structure. Background: With the advancement of science and technology, computers have been widely used in individuals and companies. For ordinary individuals, due to the maturity of multimedia technology, and the powerful ability of the computer to display realistic image effects, the display has become a computer system S1 important peripheral equipment. Currently commonly used displays are cathode ray tube (CRT) displays and liquid crystal displays (LCDs). The cathode ray tube display uses an electron beam to excite the fluorescent substance to produce various colors. Therefore, it takes 7 large power to provide the cathode ray tube to generate the electron beam and requires a large volume to absorb the cathode ray tube. If the screen displays The larger the size, the greater the need for the user to use a larger space to accommodate the cathode ray tube display, which often causes inconvenience in the display, and the cathode ray tube is displayed on the image, which will generate electromagnetic radiation, so Health effects for users1. Therefore, liquid crystal displays (Liquid Crystal Disp / a · LCD) are gradually accepted by users to replace cathode ray tube displays as mainstream products in the field, because LCD displays are not only small in size, but also low in market capitalization. In addition, The liquid crystal display will not produce electromagnetic radiation of human hair. Healthy electricity

550527 五、發明說明（3) 一般而言，直下型液晶顯示器係使用於較大顯示尺寸 的液晶顯示器，因為燈管組2 0本身可產生大範圍的發光 源，且光源直設於顯示器下方，因此不需厚重的導光板 (light guide plate)而減輕整體顯示器重量，但是由 於使用燈管組2 0的緣故，須有足夠空間來擴散光源，所以 直下型液晶顯示器本身不易做成薄型化。此外，習知技術 將控制元件安裝於反射板2 2與下框架2 4之間，因而更增加 液晶顯示器的厚度而造成使用上及安裝上的不便。550527 V. Description of the invention (3) Generally speaking, direct-type liquid crystal displays are used for large display size liquid crystal displays, because the lamp group 20 itself can generate a wide range of light sources, and the light sources are directly arranged below the display. Therefore, a heavy light guide plate is not needed to reduce the overall display weight. However, due to the use of the lamp tube 20, there must be enough space to diffuse the light source, so the direct type liquid crystal display itself is not easy to be made thin. In addition, the conventional technology mounts the control element between the reflecting plate 22 and the lower frame 24, thereby increasing the thickness of the liquid crystal display and causing inconvenience in use and installation.

Description of the invention (6) In this embodiment, one end of the base frame 56 can also be fixed to the bottom side of the main frame 42 to support the entire liquid crystal display 40 through the main frame 42. In addition, the frame 53b may be used to form another space with the side plate 59. As shown in the frame 53a and the side plate 58, the circuit board 52 may be partially attached to the side plate 58 of the reflective plate 50, and other portions Attachment to the side plate 5 9 to make full use of the space between the side plates 5 8, 5 9 and the support frame 51, or only to the side plate 5 9 of the reflection plate can reduce the thickness of the liquid crystal display 4 〇 the goal of. Compared with the external frame, the present invention is advantageous. The circuit required to use the circuit to set up the LCD display must be installed separately. However, the present invention can be used. The scope of this development layer is small and further reduced to the reflective plate. The board is located between the reflectors. Because each control panel only needs to be electromagnetic, low-production rear, components, and direct-type LCDs have multiple printed circuit assemblies with multiple control and support frames. The thickness of the side panels of the board also increases. The model using a protective layer mounted on the side plate around the board can be cost effective. In addition, it is necessary to reduce the space on the electromagnetic shielding circuit board when the space between the 5 f board and the printed board is reduced. Because the frame is designed to control each room, it is necessary to control the shadow room. The technology of the brush circuit is straightforward due to the placement. The protective layer is based on the surrounding technology, magnetic protection, and the conventional control technology. It is placed on the control signal for the inverse image signal. The existing side panel is assembled (the various controls can be used to reduce the size of the LCD. Furthermore, it is necessary to avoid the electromagnetic shielding. The technique required for the electrical layer is to integrate the control panel and the rear panel into a radiation plate. However, the board area is printed to make the panel straight down. The display is known to interfere with the technology. The protective layer is a magnetic protective material.
