Then, the control unit of the 26CH group of the control unit is tested (4) to control the weaving. C ^ As shown in Fig. 3 (4), in another embodiment, the power supply module % may include a 1321765 bi-divider 24A, a comparator 24B, and a rectifying/transforming unit 24C. In this embodiment, the two resistors (Ri R R3) and the two input terminals are respectively connected to one of the voltage dividers 24A of the voltage divider 24A. Source (Υκεπ). The output of the comparator 24B is connected to the rectification/transformation unit. According to the present invention, if the rectification/transformation unit 24C supplies the illuminating cylinder 22 pressure (VL) to be changed, the operating voltage v〇p also follows change. Therefore, the detection ^ can know whether the VL is correct. If the voltage at the voltage dividing point N1 is lower than the brilliant value, it means 0^^一目^ electric dust value. Assuming V〇P is proportional to V1, when the voltage of the voltage dividing point N1 is lower than V_', the rectifier/transformer unit 24C should be raised by V1. In this implementation, the system M S2 Jiantong shuts off the S3 touch, the sub-station m 〇 ^ ^ ^ The switch S2 is open circuit, and the voltage of the voltage dividing point N1 is the voltage division of the resistor. Hey. "^ is the value of ^. ‘Selecting the switch & or % will have a different effect on Vl. The whole voltage is different from that of the various lighting modules. The control signal generated by the control module 26 is used to determine whether the switch S2 or S3 should be turned on. In practical applications, the device 24 can of course contain more sets of resistors and switches, thereby increasing the flexibility of adjusting ¥1. In another embodiment, the power supply module 24 can include a shunt 24D in addition to the comparators 24A and 八2. In this case, the 2 = 24D system consists of two resistors (four), 115) and two switches (S4, S5) two: eight 贞 贞 发光 之一 之一 22 operating current I 〇 p. The two inputs of the comparator 24B are connected to one of the nodes N2 of the shunt 24D, which is a voltage source 0W. The wheel of the comparator is connected to the rectification unit '24C. According to the present invention, the flow (II) of the electric 8 1321765 supplied to the illumination module 22 by the right rectification/transformation unit 24c is changed, and the operation current IqP is also Change. Therefore, detecting I〇p will tell if II is correct. The voltage at node N2 is l〇p multiplied by the resistance of resistor R4 or R5. If the voltage at node N2 is lower than v臓, it means that I〇p is lower than a target current value. Assuming that I 〇 P is proportional to IL, when the voltage of the node N2 is lower than Vref2, the rectifying/transforming unit 24C should raise the IL. In this embodiment, when switch S4 is turned on and switch S5 is open, the voltage of node N2 is the product of the resistance of Iop and resistor R4. In contrast, when the switch % • is turned on and the switch S4 is open, the voltage of the node N2 is the product of the electric resistance of the resistor Rp and the resistor R5. If VREF2 is a fixed value, selecting the switch on or off will have a different effect on φ. The rectifier/variable unit 24C must be provided to the various lighting modules II. The control signal generated by control module 26 in this embodiment is used to determine that switch S4 or S5 should be turned "on". In practical applications, the shunt 24D can contain more sets of resistors and switches, thereby increasing the flexibility of the adjustment of £1. As shown in Figure (c), in another embodiment, in addition to the comparator 2, the power module 24 may comprise a capacitor array 2. In the embodiment, the capacitor array 24E is composed of a resistor _, _ capacitor sag, C2. and two switches (S4, S5), and is used to control one of the illuminating modules 22 during startup. Comparator 24B #two inputs are respectively connected to a section of the capacitor array %

Resistor R6 is connected between node N3 and an electric (Vcc). In other words, the voltage supplied to the lighting module 22 by the rectification/transformation unit s 24C is =5 and is lower in a normal mode. According to the present invention, the voltage _ C1 or C2 is charged, and thus the power consumption of the node N3 is increased. If the voltage of N3 is higher than ν_, the rectifier 24C is switched to the normal mode by the startup mode. In this implementation, when _S6 is turned on and S7 is turned off, the time at which node 9 1321765 'N3 is relocated to Vrek is determined by resistor R6 and capacitor α. When switch S7 is turned on and switch S6 is open. The time of the voltage j ν· of the node N3 is determined by the resistor R6 and the capacitor C2. If ν· is a fixed value, turning on the switch S6 or S7 will have a different effect on the time when the rectification/deformation unit % is switched to the normal mode. The period in which the rectifying/commuting unit 24C is in the startup mode may also be referred to as the startup period 发光 of the illuminating mode group 22. The length of startup required for various lighting modules varies. In this case, the control unit 26 Zhao Zhi (4) is used to determine whether the switch S6 or S7 should be turned on. In practical applications, the capacitor array 24 can of course contain more sets of capacitors and switches, thereby increasing the flexibility during the startup of the illumination module 22. As described above, the display system according to the present invention can adjust the voltage, current, and start-up period supplied to the light-emitting module according to the characteristics of a light-emitting module. Therefore, compared to the prior art, a manufacturer who produces a display system according to the present invention can use only a single power supply unit to match various specifications of the illumination, thereby reducing the hardware cost of the older display system. The present invention is intended to be more clearly described in the preferred embodiments of the invention. On the contrary, the intention is to cover various modifications and equivalents within the scope of the invention as claimed.
