TN Segment LCD for Electric Energy Meter, Gas Meter

LCD (Liquid Crystal Display) is widely used in energy meters, gas meters, water meters and other meters, mainly as display panels.

In the energy meter, LCD can be used to display information such as energy, voltage, current, power, etc., as well as prompts such as alarms and faults.
In gas and water meters, LCD can be used to display information such as gas or water flow rate, cumulative consumption, balance, temperature, etc. The industry's requirements for LCD displays mainly focus on its accuracy, reliability, stability and durability. In addition, the appearance, appearance quality and durability of LCD are also the focus of attention of manufacturers and the market.

In order to ensure the quality of the LCD display screen, corresponding tests are required, including life test, high temperature, low temperature, high humidity, low humidity test, vibration test, impact test, etc.
For application scenarios with high requirements such as energy meters, the test process also needs to pay attention to the test of key indicators such as accuracy to ensure the stability and reliability of the LCD.
