New Description: [New Technology Field] This creation is related to the structure of a kind of LED backlight module, especially one that is installed in the liquid crystal display, and uses the supporting LED group set on the strip. When the main LED group fails or the brightness is attenuated, the main light-emitting LED group is replaced by the main light-emitting LED group to maintain the brightness of the liquid crystal panel. [Prior Art] In the liquid crystal display device, a backlight system is fixed on the backlight module frame of the liquid crystal display panel to serve as a main light source for the display effect of the thin film transistor liquid crystal panel. The well-known backlight module light source has two types of cold cathode tubes (cold Cathod FlU〇rescent Lamps; CCFLs) and light-emitting diodes (LEDs), and the structure of the backlight modules can be divided into sidelights and the positions of the lamps. Straight down two. The light source of the edge-lit backlight module is disposed on the side of the module, and the wedge-shaped light guide plate 31 ′ is disposed on the back surface of the liquid crystal panel, so that the light source of the end surface of the light guide plate 31 can be uniformly diffused to the whole mold mode after multiple reflections. The group can reduce the thickness of the backlight module, so that the liquid crystal display has a thin profile (as shown in FIG. 3A). In recent years, the mature technology of LED has enabled its luminous efficiency to keep pace with the cold cathode tube, and LED has many advantages such as small size, fast response, good color rendering, etc., so that the color rendering of liquid crystal panels using LED as a light source can exceed NTsc (National Television Standards Committee) has the advantage of high color reproducibility. Furthermore, when LED is applied to liquid crystal display-related products, it is not necessary to use the complicated optical component structure of the M319429 CCFL backlight module, which can effectively reduce the thickness of the module and reduce the manufacturing cost. Therefore, the related technology using LED as a backlight module light source has become a core technology developed by the industry. In order to provide a sufficient light source for the liquid crystal display, the edge-lit LED backlight module is currently used to increase the number and arrangement density of the LEDs (321) in a single row of LED strips 32 (LED bars, as shown in Figures 3A and 3B). However, the tight arrangement will cause the heat source generated by the LED (321) to concentrate, causing the LED (321) to be affected by the aging or temperature, causing a failure or brightness degradation, which in turn affects the brightness of the liquid crystal panel. Therefore, in order to improve the above-mentioned shortcomings, the backlight module can emit a certain brightness for a long time, in order to maintain the use quality of the liquid crystal display, and prolong the use of the LED backlight module, the creator has accumulated many years of experience and continuous research and development. Improvement, there is no such creation. [New content] The main purpose of this creation is to provide a light source structure for an LED backlight module, which can extend the life of the LED by interleavingly driving the main LED group and supporting the LED group to enable the backlight module. Maintain a certain brightness for a long time. The second objective of the present invention is to provide a light source structure of an LED backlight module, which is configured by staggering a main light-emitting LED group and supporting a light-emitting LED group on a strip, and when the main light-emitting LED group is faulty, The strip is driven to support the operation of the LED group to maintain the brightness of the liquid crystal display (4). For the purpose of the above creation, the light source 6 M319429 source structure of the LED backlight module of the present invention includes at least a primary hair SLED group, at least one support light coffee group, and a strip board, wherein the LED groups Each of the electrical connections is formed on the strip-linear array, and when the main LED group fails, the strip can be controlled to operate the LED group _ operation to maintain the brightness of the liquid crystal display . When used, the fresh LED clusters are arranged on the strip in a spaced, staggered or parallel manner in a linear array. [Embodiment] Please refer to FIG. 1A, which is a first embodiment of a light source structure i for creating an LED (four) module, comprising two main LED groups G1 (111) and G2 (112), and two supporting LED groups.

The light source structure 1 of the Lm) backlight module is mounted on the side of the edge-lit LED backlight module 2 (as shown in FIG. 2), and the liquid crystal panel 21 is provided in a liquid crystal display (not shown). The required backlight. The strip 13 is a metal plate, a printed circuit board (PCB) or a flexible board for the above-mentioned LED groups (G1, G2, G3, G4) to be fixed thereto. In implementation, when the main LED group G1 (111) fails or the brightness is attenuated, the main LED group G1 (111) can be turned off by using the software setting in a manual or automatic manner, and the board is used. The u driver supports the LED group G3 (121) to replace the main LED group G1 (111), so that the backlight module continues to operate to maintain the brightness of the LCD. In contrast, when the main LED group G2 (112) fails or the brightness 7 M319429 is attenuated, the main LED group G2 (112) can be turned off manually or automatically by using the software setting, and the The strip 13 drives the LED group G4 (122) to replace the main LED group G2 (112), so that the backlight module continues to operate to maintain the brightness of the liquid crystal display. Please refer to FIG. 1B , which is a second embodiment of the light source structure 1 of the LED backlight module. When applied to the edge-lit LED backlight module, the main LED groups G1 ( 111 ) and G2 are used.
