Field of the Invention This invention relates to a backlight module, and more particularly to a backlight module for use in a liquid crystal display. [Prior Art] In recent years, many flat panel display technologies have been developed. The liquid crystal display (LCD) has gradually become the mainstream of future displays because of its low power consumption, lightness, and shortness. The liquid crystal display is mostly a back-light type liquid crystal display, and mainly includes a liquid crystal display panel at the front end and a backlight module at the rear end. Since the liquid crystal panel itself does not emit light, the panel light source must be provided by the backlight module to produce a backlight of sufficient brightness to pass light through the liquid crystal layer to the user's eyes. The backlight module includes a light emitting device (for example, a lamp tube) that provides a light source and a converter that provides an operating voltage, and the converter includes a first polarity transformer that supplies a first polarity voltage, and a second polarity transformer that provides a second polarity voltage. Connector. It is worth mentioning that the phase difference between all the first polarity and the second polarity mentioned in this paper is 180. . Please refer to FIG. 1 , which is a schematic diagram showing the connection mode of a converter and a light-emitting device of a conventional backlight module. In Fig. 1, the converter 102 requires four first polarity transformers 1 and 4 and four second polarity transformers 106 to drive the four lamps 108 of the illumination device. Since this type of connection requires the use of a large number of transformers to drive the lamps of the illuminating device, the cost of the converter is increased. Ϊ285775 -___ This is the replacement page for this year. Next, please refer to Figure 2, which shows a schematic diagram of the connection between the converter and the illuminating device of another conventional backlight module. As shown in FIG. 2, the first polarity transformer 204 and the second polarity transformer 206 respectively output the first polarity voltage and the second polarity voltage to the connector 210, so that the connector 210 simultaneously outputs the first polarity voltage and the second polarity voltage to Light tube 208. Similarly, the first polarity transformer 204 and the second polarity transformer 206 also output the first polarity voltage and the second polarity voltage to the connector 212 respectively, so that the connector 210 simultaneously outputs the first polarity voltage and the second polarity voltage to the lamp tube. 214. Therefore, in such a connection mode, a connector simultaneously outputs a first polarity power and a second polarity voltage to drive the lamp. Since the conventional connection method uses a set of first polarity transformer 204 and second polarity transformer 206 to drive two lamps of the illumination device, the two sets of first polarity transformers and the second polarity transformer can drive the illumination. 4 tubes of the device. Although this type of connection can reduce the number of transformers used, the problem of interleaving of the first polarity and the second polarity of high voltage lines occurs on the line of the converter. Therefore, this connection method often needs to be interleaved in the high voltage line of the converter. High voltage insulation treatment is carried out. A high "voltage insulation treatment method is to use the front and back sides of the converter's printed circuit board (PCB) for high voltage lines. Since the high voltage line in this way is a bare line, and the voltage difference between the first voltage and the second voltage of the tube is often from 2000 volts to 4000 volts, the printed circuit board of the converter is often unbearable. Such a large pressure difference will reduce the reliability of the product, and when the converter is attached to the back panel of the backlight module, special insulation treatment is required between the two to increase the cost. Another type of high-voltage insulation treatment 6 1285775 _____ dn... The monthly replacement (, more) is replacing the page type by using a jumper method, one of the high-voltage lines is manually spot-welded to a high-voltage insulated line. Spot welding is on the printed circuit board of the converter. Since this method requires manual spot welding, it takes time and the high voltage insulation line also causes an increase in cost. As can be seen from the above, when the backlight module uses a U-shaped or C-type lamp, the converter uses different voltage polarities for the double side drive design in order to reduce the interference to the panel. However, in order to generate voltages of different polarities to drive the lamps of the backlight module, the high voltage lines on the converter are interlaced, thereby reducing the reliability of the product, and the circuit board of the converter needs to be done. High voltage insulation treatment results in higher costs. In addition, in order to make the converters without high-voltage lines interlaced, more transformers must be used to drive the lamps of the backlight module, which also causes the cost of the converter to become higher. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a backlight module which can reduce the number of transformers used by the converter and thereby reduce the cost. Another object of the present invention is to provide a backlight module in which high voltage lines are not interlaced on the converter, thereby improving product reliability. Another object of the present invention is to provide a backlight module in which the circuit board of the converter does not need to be subjected to high voltage insulation treatment, thereby achieving the effect of reducing cost. According to the above object of the present invention, a backlight module is proposed, which is suitable for 7 1285775 94仫n year and day repair (8) is being replaced _
