Smart Embedded Displays for HMI

Highly integrated, intelligent displays are in high demand these days. Most of the time, the modern HMI (Human Machine Interface) is complex and requires more processor resources than the control of the actual application. With a smart embedded display product, DMB Technics covers a large part of the requirements for current HMI and makes computing power available where it is needed.
Customers can thus use their applications in a targeted and efficient manner and benefit from a fast time to market. Tests, qualifications, and various checks are carried out by the manufacturer in advance. The complete procurement of components is also taken over by the customers.
By focusing on industrial products, the manufacturer EDT (Emerging Display Technologies Corp.) guarantees the availability of all components used. In addition, it also supports customers in ESD/EMC matters and offers pre-certification of the products – also with regard to CE conformity.

Fast time-to-market

The use of a smart embedded product makes it possible to quickly realise a comprehensive and high-quality HMI. Not only the broad and universal range of functions, but also the excellent software tools distinguish this product range.
The simple, intuitive GUI designer (based on TouchGFX) allows customers to display their graphics on the excellent TFT displays in top quality. In addition, the manufacturer offers various software templates for free use. This means that even inexperienced developers can quickly become familiar with GUI design.

Features of the
Smart Embedded Displays

The product range supports the STM32F7xx and STM32H7xx processors. The high-performance MCUs used are based on Cortex-M7 with clock frequencies of 200 MHz and 400 MHz respectively. Smart Embedded Displays are available with 5 V and 7 V up to 26 V supply voltage. Power supply via PoE (Power over Ethernet) is available as an option. GPIO, SPI, I2C, RS232, RS485, CAN, USB and Ethernet are supported as standard interfaces.
The internal flash memory can be up to 1 MB, externally up to 64 MB are possible. The internal RAM can be up to 1 MB, externally up to 16 MB. HY4614 or ILI2511 can be used as touch controllers, and JST and the SM0 series are available as peripheral connectors.

Powerful development kits

There are several development kits available in sizes from 3.5 to 10.1 inches. They are combined with high-quality industrial TFTs in TN (Twisted Nematic) and IPS (In-Plane Switching) technology.
But also CTPs (Capacitive Touch Panels) bonded with decorative glasses can be combined as standard variants. The kits are supplied with FreeRTOS. This is a powerful real-time operating system (RTOS) based on a microkernel architecture and specially developed for embedded systems.
It allows real-time control of the board, starts within 100 milliseconds and performs its tasks efficiently.
Smart Embedded Displays are highly integrated, intelligent displays for HMI‑applications.
The standard displays have the following resolutions:
  • 3.5 inch: 320 x 240 (QVGA) &
    480 x 320 (WQVGA)
  • 4.3 inch: 480 x 272
  • 5.0 inch: 800 x 480 (WVGA)
  • 7.0 inch: 800 x 480 (WVGA) &
    1024 x 600 (WSVGA
  • 10.1 inch: 1024 x 600 (WSVGA)

TFT modules with high-quality polarisers

The TFT modules used are characterised by both bright and long-life LED backlights. High-quality polarisers such as wide viewing angles are used for optimal optics.
The kits contain the following: Controller board, CTP sensor, neutral decorative glass front, power supply, programming adapter, cable set for the power supply, programming and I/O cable set, USB memory stick with the documentation and project examples.
