The display panel is mounted on a side view of the carrier. Press, the display panel (LCDPANEL) must be powered on during the production process to perform measurements of various electronic characteristics to control the quality of the display panel. Conventionally, the display panel 5 is measured by placing the display panel 5 on a carrier i using the -bearer 2 and the socket 3, and the axle display panel 5 is transported by the carrier 1 in production. On the transport path, a detector 4 for measuring the display panel 5 is provided on the carrier i, and is composed of a plurality of detecting units mounted on the carrier i, each of which can pass through a plurality of measuring connectors 41 and signals. Line 6 is connected to the display panel 5; when the carrier 1 moves the display panel into the detection area on the transport path (not shown), the power of the detection area can be used to drive the inspection of the carrier 1 The operation 'measures the display panel 5, and a signal connection seat driven by the cylinder is arranged at the bottom of the detection area, and is connected to the detector 4 to transmit signals between the inside of the detector 4 and the outside. However, the demand for using the LCM (LiquidQystalModule) test product and operating on the client production line has progressed toward a large size, a high resolution, and a high update rate, and the larger the size, the longer the distance of the video signal transmission line. If the transmission is continued in the original manner, the higher the transmission frequency of the high-frequency video signal may be due to the variety of transmission conductors, the number of transmission stages is too large, and the signal is thus distorted, resulting in the 200840215 facet abnormality being easily restricted in the production line.

In the embodiment of the prior art, the number of channels converted to LVDS by several is the same as the number of channels converted to TTL2 by & LVDS. Therefore, its application level can be further improved. Repair|, consider increasing the number of transmission channels to reduce the I-pass data and the fundamental frequency, and achieve longer-distance transmission, and is not limited to special wire/joint/PCB quality problems, but also meet customer requirements. Therefore, how to solve the above problems caused by the signal output of the video signal generator and the detector on the carrier being too far apart from each other will be proposed by the present invention.

The number of transmission channels caused by the channel π 'axis light differential reduction interface 14 can be at least 1, and the maximum can be 16, but if there are other in the future In the embodiment, when the number of ranges is not included, the one-channel number receiving conversion module 16 can receive and electrically connect with the output low-power county source device 11 and the channel number conversion transmission module 12 to perform channel Number control signal And the transmission and reception of the data, wherein the plurality of signal transmission interfaces between the channel number conversion transmission module 12 and the channel number receiving conversion module 16 are two types, and the low voltage difference including the data can be transmitted. The signal interface 13 and the transmission channel number control signal interface 17 , the number of transmission channels caused by the low voltage differential signal interface 13 can be at least 1, and the maximum can be 16, but in the future, if there are other embodiments, 'when not limited to this a range of the number; and a device to be tested 15 that can receive the low voltage differential signal, and can be electrically connected to the channel number receiving conversion module 16 via a plurality of low voltage differential signal interfaces 141 for receiving data; The control module 10 is electrically connected to the image source device 11, the channel number conversion transmission module 12, and the channel number receiving conversion module 16 and the device under test 15 to be converted between the image source device 11 and the channel number.

Therefore, the present invention can reduce the transmission data and the fundamental frequency by increasing the number of transmission channels. (2) By reducing the number of transmission channels, the transmission data and the fundamental frequency can be increased. If the number of channels between the image source device and the display device is different, the channel number can be switched through the present invention for flexible application. Please refer to the fifth figure, which is a first preferred embodiment of a transmission channel number conversion system for a low voltage differential signal of the present invention. As shown in the figure, there are two kinds of signal transmission interfaces between the 200840215 source device u' and the channel number conversion transmission module 12, and the low voltage differential including the data can be transmitted. The signal interface 14 and the transmission channel number control signal interface 17', so the number of transmission channels caused by the low voltage differential signal interface 14' is 2, and the transmission number conversion transmission module 12, _ is cut into 4 The low-level differential signal interface 13, that is, the number of channels is 4. Therefore, the 'base frequency divided by 2' is transmitted at a lower frequency, so that the transmission distance can be increased, and the data is compressed into two low-voltage differential signal interfaces 141, resulting in a compression of 2 channels. The frequency is multiplied by 'to match the device to be tested 15, and the required number of channels is normally displayed.

As shown in the ®, the towel is in the image of the second secret: the channel number conversion transmission module is between the plurality of signals - the canister differential signal interface surface 14 of the data transfer, so the low voltage difference The signal number 12,,, nt?1"^ is 1' and the number of transmission modules transmitted through the channel number is 4 1 knives. The interface has 4 low-voltage differential signals 13, which means that the channel conforms to the device to be tested. The work of the second::: Zhongji 200840215, please refer to the seventh figure, which is a third preferred embodiment of the transmission channel number conversion of the low voltage differential signal of the present invention. The plurality of signal transmission interfaces between the 1" and the channel number conversion transmission module 12" can transmit a low-level differential signal interface 14"' and a transmission channel number control signal interface 17 including a dragon. ', so the low power, "the number of transmission channels is 丨, and the channel number conversion transmission module 12"' 'cuts the data into two low-voltage differential signal interfaces 13", that is, the number of channels Is 2. Therefore, the fundamental frequency is divided by 2, and transmitted at a lower frequency, so that the transmission distance 're-transmission channel number receiving transfer surface group 16,' can be increased, and the data is compressed into 合 data of '2 ϋΊΜϋ & ΙίΙϋ φ of 2, Multiply the base frequency by 2 ' to match the number of channels required for the device under test for normal display.
