DWIN specializes in designing and manufacturing LCD-TFTs integrated with proprietary integrated circuits, allowing them to be easily implemented in a wide range of applications.
Smart displays – what is it?
Smart displays on LCD-TFTs are state-of-the-art HMI devices in which the LCD-TFT and touch panel module are integrated with the processor and interfaces. Unlike traditional solutions, they do not require additional controllers. You can control all the functions with a touch on the screen. The introduction of touch operation ensures precise user interaction without the need for additional elements such as mechanical buttons.
With innovative graphical development systems such as DGUS (DWIN Graphic Utilized Software, a tool provided by DWIN), users can quickly and intuitively create user interfaces without writing complex code.
Smart displays by DWIN
Among the solutions by DWIN is a wide range of LCD-TFTs with diagonal sizes ranging from a few inches to tens of inches, making them adaptable to different devices. The diversity of optical parameters in individual models allows them to be tailored to the requirements of applications, especially those that can be described as “standard”, not intended for operation in demanding conditions; these would be, for example, selected devices used in commerce. The 7-inch HDW070-008LZ05 module, with its high resolution (1024×600 px) and brightness (600 cd/m2), full viewing angles (85°/85°/85°/85°) and wide operating temperature range (-20~70°C), can be pointed out as a model that will work well in such applications. What’s more, it is integrated with a capacitive touch panel. Its lifespan is specified at a minimum of 20,000 hours.
Also worth noting is the round LCD-TFT variant by this supplier – it’s a 2.1-inch model DMG48480C021_02WTC with a resolution of 480×480 px, brightness of 350 cd/m2, full viewing angles – 85°/85°/85°/85° and an operating temperature range of -20 to 70°C. It can be used, e.g., in consumer electronics – coffee makers, audio and video equipment, weather stations, etc.
Ready-made solutions for IoT
DWIN also offers products created for IoT (Internet of Things) systems. These are small-sized LCD-TFTs, also in the form of ready-made devices, to be implemented in home or office space automation systems. Some of them are also equipped with additional components, such as temperature sensors, proximity sensors, built-in speakers, or WIFI modules; in many variants, you can design the user interface yourself thanks to the DGUS platform.
The table presents selected models of LCD-TFTs representing a series designed for use in IoT systems.
| model | size | resolution | brightness | viewing angles | interface | touch panel | enclosure |
| TC040C14U04 / TC040C14W04 | 4.0” | 480×480 px | 250 cd/m2 | 85°/85°/85°/85° | RS485 | yes, capacitive | yes |
| TC041C11U04 / TC041C11W04 | 4.1” | 720×720 px | 250 cd/m2 | 85°/85°/85°/85° | RS485 | no | yes |
| TC070C22U00 / TC070C22W00 | 7.0” | 1024×600 px | 250 cd/m2 | 85°/85°/85°/85° | RS485 | yes, capacitive | yes |
| TC48480C040_06WTC | 4.0” | 480×480 px | 250 cd/m2 | 85°/85°/85°/85° | RS485 | yes, capacitive | no |
Summary
Thanks to their advanced technology, wide selection of interfaces, and programming flexibility, smart LCD-TFTs are used in many industries.
Unisystem’s cooperation with DWIN provides Polish companies access to state-of-the-art HMI panels that significantly improve human-machine interaction. DWIN’s intelligent LCD-TFT displays stand out from other such products due to their attractive price. It is certainly worth considering implementing DWIN brand modules in projects requiring cost optimization.
