1. "LIGHT" linked with GND, the backlight to be lit.
2. Need you to compress the screen and PCB tighter, might got loose after the delivery.
3 Use a 3.3V controller, otherwise the display could be quite vague.
Power supply voltage:2.7V-3.3V,5V is OK,but part of the screen becomes black when tested
Data interface level:2.7-5V
Backlight power supply voltage:highest 3.3V

4ďĽŽDIN-----------serial data line
5ďĽŽCLK------------serial Clock Speed
7ďĽŽLIGHT--------- backlight control terminal
84 X 48 dot matrix LCD,can show 4 lines of characters
Use serial interface communicate with the master processor,the number of interface signal line reduced greatly, only 8 signal lines including power and GND.Support different types of MCU,such as the SPI,MCS51 serial mode 0 of AVR.Transfer rate up to 4Mbps,can full speed write display data without waiting time.
Can use the conductive glue to connect the module with the printed board,without connecting cable.The metal hooks on the module can fix the module on the printed board,which is very easy to install and replace.
LCD controller/driver chip has been bound to LCD chip,the volume of LCD is small
Low power supply,the working current in normal situation is lower than 200ÎĽA,and has power-down mode.
