2.Precautions in use of LCD Modules (1) Avoid applying excessive shocks to the module or making any alterations or modifications to it. (2) Don’t make extra holes on the printed circuit board, modify its shape or change the components of LCD module. (3) Don’t disassemble the LCM. (4) Don’t operate it above the absolute maximum rating. (5) Don’t drop, bend or twist LCM. (6) Soldering:only to the I/O terminals. (7) Storage:please storage in anti-static electricity container and clean environment. 3.

10.Display Control Instruction The display control instructions control the internal state of the NT7108. Instruction is received from MPU to NT7108 for the display control. The following table shows various instructions. GE-G12864A-TFH-V/RN page 11 / 21 13.07.
11.Detailed Explanation The display data appears when D is 1 and disappears when D is 0. Though the data is not on the screen with D=0, it remains in the display data RAM. Therefore, you can make it appear by changing D=0 into D=1. SET ADDRESS (Y ADDRESS) Y address (AC0-AC5) of the display data RAM is set in the Y address counter. An address is set by instruction and increased by 1 automatically by read or write operations of display data.
When BUSY is 0, the Chip is ready to accept any instructions. ‧ON/OFF When ON/OFF is 1, the display is OFF. When ON/OFF is 0, the display is ON. ‧RESET When RESET is 1, the system is being initialized. In this condition, no instructions except status read can be accepted. When RESET is 0, initializing has finished and the system is in usual operation condition. WRITE DISPLAY DATA Writes data (D0-D7) into the display data RAM. After writing instruction, Y address is increased by 1automatically.
