这样直接接5V肯定不行的，这个1602应该是3V的，可以参考http://www.everbouquet.com.tw/products3.htm 未命名.jpg

同样使用NT7607，电压是3V，NT7607的资料没找到，找到了NT7606的pdf，可供参考

General Description

The NT7607 is a low power CMOS LCD controller and driver designed to drive a dot matrix LCD display

of 2-line or 3-line by 16 characters with 5 ??8-dot format. All necessary functions for the display are

provided in a single chip, including on-chip generation of LCD bias voltages, resulting in a minimum of

external components and lower system current consumption. The NT7607 interfaces to most

micro-controllers via a 4-bit / 8-bit parallel bus or via the 3SPI / 4SPI serial interface. The chip contains a

character generator and displays alphanumeric character.

楼主，液晶焊接最好用防静电的烙铁。
