INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a flat panel display, and more particularly to a liquid crystal display. [Prior Art] With the continuous innovation of the information and communication industry, the market for liquid crystal display (LCD) has been booming. The liquid crystal display has the advantages of high quality, small size, light weight, low driving voltage, low power consumption, etc., so it is widely used in personal digital assistants; PDA), mobile phones, video recorders, notes Consumer communications or electronic products such as computers, desktop displays, automotive displays, and projection televisions. Coupled with the rapid advancement of integrated circuits (ic) and LCD manufacturing technologies, these consumer communications or electronic products are also moving toward light, thin, short and small trends. Especially in terms of computer products, in addition to high-performance, high-speed desktop computers, portable notebooks are highly valued and valued. Traditionally, small-sized liquid crystal display modules have been fixed in a module frame by a liquid crystal panel and a backlight module. And using the flexible characteristics of the Flexible Printed Circuit Board (FPC), one end is connected to the liquid crystal panel, and the other end is folded back behind the module frame. The backlight module illumination source formed by the light emitting diode (LED) is mounted in the frame by another flexible circuit board to provide a light source. The flexible circuit board of this LED is then connected to the system flexible circuit board (Main Flex) connected to the liquid crystal panel by means of soldering or a connector. Refer to Section 4 1323365 to show that the two flexible boards are joined by soldering and then folded back behind the module frame in the direction of the arrow. In addition, some of the conventional liquid crystal display modules have the LED light source disposed on the flexible circuit board at the same time, and the flexible circuit board is folded back and taped to the rear of the frame to fix the flexible circuit board of the system and the LED The light source is folded over the back of the display module. Referring to Figure 5, a conventional flexible circuit board is shown which is folded back in the direction of the arrow and adhered to the frame. Whether using a single flexible circuit board or a small liquid crystal display module using two separate flexible circuit boards, since the flexible circuit board is folded back and adhered to the rear of the frame, the thickness of the module is increased, thereby enabling the application. The total thickness of the electronic device of the liquid crystal display module is increased, which is disadvantageous for miniaturization of the electronic device. In addition, the connection of two independent flexible circuit boards increases the cost of the connector or the connection, and thus increases the manufacturing cost of the liquid crystal display module. However, when a single flexible circuit board is folded back and adhered to the rear of the module, it often causes the disengagement due to the resilience of the circuit board, so that the position of (10) is shifted, which causes the optical brightness to be seriously shifted. Therefore, how to effectively reduce the appearance size and manufacturing cost of the small-sized flat display device, and to provide a fixed structure of the flexible circuit board and the LED flexible circuit board are desirable.
