Supporting larger and higher resolution displays than ever before

Bridgetek has announced its embedded video engine (EVE) platform. The BT817 and BT818 represent the company’s fourth generation of EVE products and help those with little or no relevant experience to build advanced HMIs with high degrees of differentiation.

These new graphic controller ICs are aimed at retail, digital signage and office management systems, as well as public information units, domestic appliances, vending machines, training/educational equipment, store/mall direction finding systems and interactive exhibits. They can meet the necessities of HMIs rendered on far larger format displays and provide greater resolution levels, too.

Suitable for use with 1Mpixel displays, the devices support resolution numerous options - including 1920 x 480, 1440 x 540, 1280 x 800, 1024 x 600, 800 x 600, 800 x 480, 480 x 272, etc. Each has a 1Mbyte embedded graphics RAM, and this can be increased by attaching an external NOR flash memory through the QSPI interface. Due to the object-oriented approach, there is no necessity for a frame buffer to be included in the HMI system. Also, by using adaptive scalable texture compression, it is feasible to lower the system’s graphics processing overhead. This also indicates better use can be made of the available data storage capacity, so that bigger items can be accessed and more effective HMI content provided.

“EVE, and the unique object-based architecture that it relies upon has already made a huge impact on the way that HMIs are now constructed, with the display, touch and audio aspects all being addressed via a single chip. It has streamlined the whole process and reduced the bill-of-materials costs involved significantly,” states Bridgetek’s founder and CEO Fred Dart. “Through the latest additions to this product family, we can assist our OEM partners in bringing touch interaction to a plethora of new applications where larger format displays are employed.”
