Dot matrix COG smart electric meter LCD

The utility model discloses a dot matrix COG smart electric meter LCD, it includes: IC, PCB board, polaroid, glass substrate and display casing, it still puts the static line including being located ESD between polaroid and the glass substrate, ESD put the static line and is arranged insidely and connect in the earthing terminal of PCB board at the display casing all around, what the static line was put to ESD walks that the line is terminal to be equipped with the cockscomb structure and to release a little, the mode that the VSS and the VDD that are equipped with in the display casing walkedthe line is described for rectangular pulse, it is poor that antistatic effect has been solved to this display, operational temperature range is narrow, the problem of moisture -proof thermal reliability difference. 本实用新型公开了种点阵COG智能电表液晶显示器，它包括：IC、PCB板、偏光片、玻璃基板和显示器壳体，它还包括位于偏光片和玻璃基板之间的ESD放静电线，所述的ESD放静电线被排布在显示器壳体内部的四周并连接于PCB板的接地端，ESD放静电线的走线末端设置设有锯齿状泄放点，显示器壳体内设有的VSS和VDD走线的方式为矩形脉冲状，该显示器解决了抗静电能力差，工作温度范围窄，耐湿热可靠性差的问题。
