For various flat panel display technologies,TFT-LCD(Thin FilmTransistor-Liquid Crystal Display)
technology dominates the flat panel display market due to its low operating voltage,low power
consumption,longlife,noradiation and low cost characteristics.The driving system of the TFT-LCD
panel consists of a gate driver GD(GateDriver),a source driver SD(Source Driver)and a timing
controller T-CON(TimingController).The T-CON converts the synccontrol signal and data signal
received from the signal source to specific input signals required by the GD and SD respectively,and
sends the data signal to each SD through the interface protocol.As the main stream display technology,
TFT-LCD is developing towards a largescreen,high resolution and high color depth,resultingin a
dramatic increase in the amount of transmission data.The performance of the interface protocol is
directly related to quality of the display.Therefore,for various TFT-LCD display technologies,the
interface protocol is the keypoint to determine whether the data signal between T-CON and SD can be
transmitted correctly.

advantagesofthesecond-generationinterfaceprotocol,the point-to-point structure greatly reduces
the number of transmission lines,and the signal line impedance is not affected by SD loading.These
advantages ensure data transmission stable and reliable based on the point-to-point interface protocol,
and they support large-size,high-speed,high-resolution,and high-color depthTFT-LCD.
EXV9210 is a P2P signal converter,which can convert P2P signal to HDMI signal,or directly display
the signal image.At present,there are many types of P2P signals on the market including CSPI,CEDS,iSP,
EPI,etc.EXV9210 can directly convert these P2P signals into image signals for display on a 5-inch screen,
or convert these signals into HDMI signals on external display.EXV9210 makes production testing and
after-sales maintenanceeasy and fast.
EXV9210 support stand-alone debugging function.If you use this function,you should first exit PC
debugging function and then press“RESET”button in tester device.After that,you can use tester device
buttons to debug functions you need.While you use PC debugging function,all tester device buttons will
be invalid.EXV9210 support English version menu.
Note:EXV9210 can communication with PC by USB or RS232 interface to fulfill FCT function(More
details,you can reviewEXV9210 user guide).
