The general control signal interface 64 is the RS_232 signal interface, and the general control signal cable 82 is the RS-232 cable. M357153 However, the general projector 6 has the following disadvantages: Firstly, when the projector 6 is in operation, the power cable 80, the image signal cable 81 and the control signal cable 82 need to be connected at the same time, which may cause the cable to be difficult to organize and easy to play. Problems such as long junction, installation and disassembly time; and second: the projector 6 must have a power interface 62, an image signal interface 63, a control signal interface 64 and its corresponding connector (not shown), so the projector 6 The volume cannot be miniaturized. [New Content] The main purpose of this creation is to provide a projection apparatus which is simple in structure and easy to use in view of the defects of the above-mentioned conventional techniques. In order to achieve the above object, the creative projection device is connected to the image signal generating device, and comprises a USB interface, a first conversion unit, a second conversion unit, an image display module and a voltage control module, and the USB interface is connected to the image signal generating device for receiving The differential signal signal and the power source sent by the image signal generating device, the first conversion unit is connected to the USB interface for receiving the differential mode signal and converting into a digital three primary color signal. The second conversion unit is connected to the first conversion unit for receiving the digital three primary color signals and converting into a low voltage differential mode signal, and the image display module is connected to the second conversion unit for receiving the low voltage differential mode signal and receiving the received signal according to the received signal The low voltage differential mode signal displays an image, and the voltage control module is connected between the USB interface and the image display module to receive the power of the USB interface and change the voltage of the power supply, and send the changed voltage to the image display module. Therefore, the projection device only needs to connect the image signal through a USB cable to generate the shortcomings of the M357153 art, and has the advantages of receiving signals and power at the same time, which not only overcomes the advantages of simple structure and easy use of the prior art.

Please refer to the second figure, which is a block diagram of the control module 1G of the present projection device 1 and a control module. 10 is provided with a micro processing unit 1 , a first conversion single phantom 1 , a second conversion unit 102 , a voltage control module | and 1 〇 3 , a switch module 1 〇 4 and a drive module. The first conversion unit ΗΠ Connecting the USB interface 12 and the second conversion unit, the first conversion unit 7L 1G2 is connected to the micro processing unit (10) and the image display module u, and the voltage control module 103 is connected to the USB interface 12, the micro processing unit 1 and the switch module 1〇4. The switch module, 'and 104 is connected to the micro processing unit (10) and the image display module η, the drive module 105 is connected to the USB interface 12, the micro processing unit a (9) and the image display u, and the micro unit M357153 is connected to the image display module. Group n. The first conversion unit 101 receives the differential mode (Dif) issued by the USB module 丨2 Fermenting a signal and converting the differential mode signal into a digital three primary color (RGB) signal, the second converting unit 102 receives the digital RGB signal emitted by the first converting unit, and converts the digital RGB signal into a low voltage differential mode signal ( LVDS) signal, and send lvds signal to image display module 11, image display module 11 displays image according to received LVDS signal. Voltage control module 1〇3 receives power from USB module 12 to change its voltage and Provided to the switch module 1〇4, the switch module 1〇4 is used to transmit the changed voltage to the image display module U or cut off the voltage transmission. The drive module 1〇5 receives the power generated by the USB module 12, The current is adjusted and the adjusted current is transmitted to the image ", the display module 11 to drive the light-emitting elements (not shown) of the image display module ii, such as 'light-emitting diodes. The control module 103 has a boosting unit and a step-down unit (not shown in FIG. 3). The boosting unit boosts the voltage of the power supply from the usb module 12, and transmits the boosted power to the switch module 1〇4, and the step-down unit is lowered. USB module 12 is issued The voltage of the power supply, and the step-down power is transmitted to each module to provide the corresponding working voltage to each module. The processing unit 100 sends a driving signal to the voltage control module i and the switch module 104 to simultaneously drive The voltage control module 1〇3 and the switch module 1〇4 enable the voltage control module 1〇3 to change the voltage of the USB contact 12 to generate power, and the switch module 1〇4 transmits the changed voltage to the image display module u. Or, let the switch module cut off the transmission of the M357153 voltage. The micro processing unit 100 sends a control signal to the driving module 105 for controlling the driving module 105, so that the driving module 105 adjusts the received current according to the control signal, and transmits the adjusted current to the image display module 11 to The light emission luminance of the light emitting element of the image display module 11 is controlled. Microprocessing unit 100 also sends a control signal to second conversion unit 102 to control the operation of second conversion unit 102. In a specific implementation, in order to reduce the cost, reduce the volume, and increase the brightness of the projection, the image display module 11 may be selected as a single crystal liquid crystal display panel (LCOS). Please refer to the third figure, which is another schematic diagram of the projection device 1 connected to the computer 2. The USB interface 12 of the projection device 1 can be simultaneously connected to the first USB interface 20 and the second USB of the computer 2 by the USB divergence cable 4. In the interface 21, the computer 2 can transmit power and signals to the projection device 1 through the first USB interface 20, and only provide power to the projection device 1 through the second USB interface 21. The first USB interface 20 and the second USB interface 21 can provide a larger current to the projection device 1 in parallel by the USB divergence cable 4. Therefore, the projection device 1 can select the image display module 11 having higher brightness to improve the projection brightness of the projection device 1. In summary, the present projection device 1 only needs to simultaneously receive signals and power through the USB interface 12, and the differential mode signal sent from the USB interface 12 is converted into a digital RGB signal via the first conversion unit 101, and then via the second conversion unit 102. The digital RGB signal is converted into an LVDS signal and transmitted to the image display module 11 to display an image. The power supplied by the M357153 USB interface 12 is changed by the power supply control module ι〇3 and sent to the shutdown module 丨04. The shutdown module 1G4 transfers the voltage to the image display module Π, or (10) the voltage is transmitted. The _ touch (10) is used to adjust the current sent by the interface 12 and transmit the adjusted current to the image display module n to change the display brightness of the image display module 11. The micro processing unit 1GG sends a shaft signal to the voltage control module (8) and the switch module 104 to drive or turn off the voltage control module 1〇3 and the switch module 1〇4, and the micro processing unit (10)S outputs a control signal to the second conversion unit 1 〇2 and the driving module 1〇5 to control the operation of the second converting unit 1〇2 and the driving module 1〇5. Therefore, the creation projection apparatus i only needs to connect the first (four) interface 2 〇 or the second deletion interface η of the computer 2 through the bar line gauge 3 or the coffee branch line thin 4 to simultaneously receive the signal and the power supply only to overcome the knowledge. The shortcomings of the technique are more simple in structure and easy to use.
