As a reliable partner in the field of industrial human-machine interaction, HOTHMI offers a full range of high-quality character dot-matrix LCD modules, dedicated to providing your devices with clear, stable, and economical information display solutions. Our products are based on mature technologies such as STN and are widely used in industrial control, instrumentation, medical equipment, smart homes, and consumer electronics.

This summary outlines the common sizes and resolutions available for Square TFT LCD Displays. These displays typically range from compact 0.96-inch modules used in wearables to larger 15-inch panels for industrial HMIs. Common resolutions include 240x240 for small 1-2 inch screens, 480x480 and 720x720 for 3-5 inch smart devices, and 1024x1024 or 1920x1920 for larger professional monitors. The selection of a specific Square TFT LCD Display depends on the application's requirements for pixel density, viewing distance, and the complexity of the user interface.


In the field of display technology, cost has always been the key factor determining large-scale application. STN LCDs, due to their relatively simple structure, do not require the expensive thin-film transistor arrays of TFT LCDs, nor do they require the complex organic light-emitting materials and precision packaging processes of OLEDs. This cost advantage, from materials to manufacturing processes, makes STN LCDs highly competitive in price.

At the beginning of spring, we frame the first light of the year with an LCD Display—where clarity meets renewal.

An LCD display module is a fully integrated vision system that combines a liquid crystal panel, driving circuitry, and standardized interfaces into a single functional unit. This plug-and-play design simplifies the integration process, allowing engineers to integrate complete LCD display solutions without developing complex driving electronics. Our portfolio includes character and graphic LCD displays, offering both traditional modular configurations and space-saving COG (Chip-on-Glass) architectures. Each LCD display can be customized with a variety of backlight options, including monochrome yellow/green, blue, white, red, and full RGB backlighting, to meet specific visual and environmental requirements.
