New description: [New technical field] This is a kind of soft printed circuit board, especially a straight strip body which can be bent by a continuous curved plate with a small length to form a longer length. A flexible printed circuit board that is bent at 0 degrees. [Prior Art] In the past, electronic devices such as flat-panel displays for notebook computers have used cold cathode fluorescent lamps (CCFLs) as backlights. In order to save energy, reduce thickness, and extend the use time, light-emitting diode strips with light-emitting diodes mounted on flexible printed circuit boards have been introduced, and they are used as backlights. The related technologies and equipment for displays below 7 o'clock are quite mature. The invention relates to a light-emitting diode light bar which is applied as a backlight source for a liquid crystal display of 7 inches or less. In order to save layout space and material utilization rate, the flexible printed circuit board of the light-emitting diode light bar is mostly formed into a u-shaped body. As shown in Figure 7, 'each, the flexible printed circuit board (2G) contains - the first straight strip (1), the younger section (22) and the connecting section (23), the first straight section (2) And the second straight segments (22) are unequal in length, and the ends are aligned and arranged in parallel, and the engaging segments (23) are coupled to the first straight segment (21) and the second straight segment (22) opposite to each other. The end. A U-shaped body is formed, and a copper circuit is printed on the flexible printed circuit board, and the light-emitting diodes are respectively provided with electrical connection. "Hai U-shaped LED light bar is applied to the backlight of the liquid crystal display, and the U-shaped light-emitting one-pole light bar is divided into an array, and the light of each group is divided into an array. The diode strips are arranged opposite each other with the shorter ends of the second 3 M366266 straight strips (22), thereby constituting a light source required to meet the backlight of the liquid crystal display. However, the application of the current LED strip has been developed towards the large-scale display. Therefore, it is inevitable for the flexible printed circuit board to lengthen its length for the LED strip to meet the future development trend. However, when the flexible printed circuit board lengthens its length, due to the layout space, material utilization rate and limitations of the process equipment, the current 7-inch process equipment that has been developed and used skillfully cannot be used to manufacture more than 7 inches of light. "Polar light strips" so how to use the existing process equipment under the existing small-scale LED light strip manufacturing technology, and to produce a larger length of light-emitting pole light strips, which is currently being researched by the industry. Question. [New content] This is the main purpose of i] to provide a soft printed circuit, and to use it to make use of the existing small-size LED light strip manufacturing technology and process recognition, and to create a larger Light-emitting diode strips of length.
