Eastern Display manufactures various types of character dot matrix LCD modules and graphic dot matrix LCD modules. The display modes include Yellow-Green STN, Blue-White STN, and Gray-Black FSTN, among others. The production processes incorporate COB technology and COG technology. Paired with LED backlight of different colors, these modules can display various characters and graphics. They are easy to use, offer high reliability and cost-effectiveness, and provide diverse options, making them widely used in various types of power meters.
Power meters are used for real-time monitoring, metering, and displaying electrical energy parameters. LCD modules have become the preferred display solution for the vast majority of power meters due to their low power consumption, high contrast ratio, and the ease of controlling their digital interfaces. Among them, dot matrix LCD modules can meet the diverse display requirements of power meters, ranging from simple to complex. They can be used in electricity meters, power monitoring equipment, smart control systems, charging piles, power relay protection instruments, power network equipment, harmonic analyzers, and other power instruments.
Character dot matrix LCD modules (such as the common 16x2, 20x4, etc.) are specifically designed for displaying numbers, letters, and a small number of custom symbols.
They are suitable for displaying the most critical electrical parameters, such as Voltage (V), Current (I), Active Power (kW), Power Factor (PF), Frequency (Hz), etc. The data display is orderly and clear at a glance, making them highly suitable for scenarios like distribution cabinets and terminal meters where only core data reading is required. Their drive circuits are simple, costs are low, software development and maintenance are easy, and they demonstrate excellent stability and reliability even in harsh industrial environments.
Graphic dot matrix LCD modules (such as 128x64, 240x320, etc.) can freely render graphics, text, and curves.
They can display complete text menus, detailed parameter setting options, and event logs. They can also plot voltage and current waveform, as well as historical trend curves for parameters like power and load, providing an intuitive basis for fault diagnosis and electricity usage optimization.
