COG 240×128 LCD Display Module | Industrial HMI Graphic Screen – Wide Temp, Low Power

Unbreakable Clarity, Built to Last: The Industrial-Grade COG 240×128 Graphic LCD Module

Engineered for mission-critical environments where reliability is non-negotiable, our COG (Chip-on-Glass) 240×128 LCD Display Module redefines durability and performance in human-machine interfaces. This graphic dot-matrix screen integrates the controller directly onto the glass substrate, eliminating fragile connectors and circuit boards to deliver exceptional resistance to shock, vibration, and electromagnetic interference. With a crisp 240×128 pixel resolution, it provides ample space for complex data visualization, real-time graphs, multi-language menus, and system status alerts.

Featuring a wide operating temperature range of -30°C to +85°C and ultra-low power consumption, this module is the definitive choice for 24/7 industrial applications. The 6:00 o’clock viewing angle ensures optimal readability from a standard operating position, while options for transmissive, transflective, or reflective modes with LED backlight (white/blue/green/amber) guarantee perfect visibility in any lighting—from pitch-dark server rooms to sun-drenched factory floors.

Technical Specifications Table

COG 240×128 Graphic LCD Display Module is a custom-designed display component exclusively for Thermo King and Carrier refrigeration equipment. Boasting high stability and extreme environment resistance, it has become a preferred display solution for cold chain transportation and industrial temperature control devices. Fully compatible with the original equipment specifications, it ensures precise operational performance.

The module adopts an FSTN positive transflective LCD panel, which innovatively solves display challenges under varying lighting conditions—delivering sharp and clear images whether exposed to direct outdoor sunlight or low indoor light. Equipped with a standard 6 o’clock viewing direction, it aligns with the equipment’s operational viewing angle requirements, enhancing the human-machine interaction experience. Adopting a 1/128 Duty cycle and 1/12 Bias drive method, it features fast display response, no image retention, and far superior operational stability compared to ordinary LCD modules.

In terms of electrical performance, the module is compatible with a VDD operating voltage of 3.0V and a Vop driving voltage of 13.6V. It is equipped with a high-performance UC1608X or equivalent driver IC, combined with a precision COG + FPC connection method, enabling efficient transmission and strong anti-interference capability, which effectively reduces the failure rate during equipment operation. Tailored for the harsh operating environments of industrial and cold chain equipment, the module offers excellent temperature range adaptability, with an operating temperature range of -30°C to +80°C and a storage temperature range of -40°C to +85°C. It maintains stable operation even in extreme conditions such as severe cold and high temperatures, suitable for various outdoor, warehousing, and vehicle-mounted working conditions.

The backlight system consists of 6 white LED light sources, with a VF voltage range of 16.8-19.2V and an IF operating current of 15mA. It features uniform brightness and optimized energy consumption, balancing clear display and low power requirements to extend equipment battery life. All components and materials of the product strictly comply with the EU RoHS directive, free of harmful substance residues, meeting global environmental standards and adapting to enterprises’ green production and export compliance needs.

As a dedicated supporting display module for Thermo King and Carrier equipment, this product integrates original equipment compatibility, weather resistance, and environmental friendliness. Widely used in core scenarios such as refrigerated trucks, refrigeration units, and temperature control devices, it provides reliable support for equipment operation status display and parameter adjustment, making it a cost-effective choice for equipment maintenance replacement and new product matching.
