Block further includes data analysis and diagnostic module, voltage sample module, backlight interface module and display Signal interface module；Information
Display module electric connection of power supply power supply module；Data analysis is electrically connected information display module with diagnostic module；Voltage sample module
It is electrically connected data analysis and diagnostic module；A current/voltage-converted module, current/voltage are electrically connected inside backlight interface module
Conversion module is by the total current value conversion voltage value of backlight interface；It shows and is electrically connected a current/voltage inside Signal interface module
Conversion module, current/voltage-converted module will show the total current value conversion voltage value of signaling interface；Voltage sample module is electrically connected
Connect backlight interface module and display Signal interface module.
The utility model has the advantages that：Due to only to the driving of liquid crystal display and backlight driving voltage and electric current carry out
It acquires and analyzes, do not modify to liquid crystal display itself, therefore the liquid crystal display of different model, size can be accessed
