Description

Bridgetek BT820B MCU

The BT820B represents the fifth generation of the Embedded Video Engine (EVE) family, designed for creating advanced graphical interfaces in embedded systems. It enables the development of sophisticated, touch-friendly HMIs on large LVDS displays while retaining the familiar object-oriented programming model from previous EVE iterations.

This powerful graphics controller drives high-resolution LVDS displays (up to 1920 x 1200), offering smooth and complex interface rendering through a dedicated frame buffer in external DDR3 SDRAM, along with a 16 Kbyte display list. With direct access to storage devices like NOR/NAND Flash and SD cards, the BT820B can retrieve and display images, videos, animations, and fonts without overburdening the host MCU’s flash memory.

It also integrates live video seamlessly (up to 1920 x 1200 at 60fps), with an LVDS video input port that supports real-time video processing, effects, and image enhancements.

Touch functionality is enhanced, with support for external capacitive touch controllers through an I2C interface. Audio playback and effects are also supported, using either stereo PWM/Delta-Sigma or I2S outputs.

High brightness, IPS TFT

Typical surface luminance for a high brightness, IPS TFT displays is 800 up to 1000 cd/m² which means it is very bright even outdoors. The full viewing angles allow the user to interact with the display in a natural and intuitive way from every side. Please see the datasheet for more features.

Industrial Touch Screen

Reacts to the slightest touch

The PCAP (Projected Capacity touch panel) is classified as ‘industrial’ (as opposed to ‘consumer’) when it is able to operate correctly in more demanding, harsh conditions (i.e. disturbing electromagnetic fields around causing interferences with panel controller, water droplets present in the surrounding area also on panel glass), and react properly when touched by hands in gloves. It can be tuned at the factory, detect touch through thicker glass layers than consumer panels (6mm thick glass layer was tested with success in the Riverdi lab) and it uses an industrial grade chip controller. Such controllers have industrial manufacturer’s guidelines implemented and are guaranteed to be manufactured typically from 10 to 15 years without any changes.

Main features:

• ILITEK Touch IC- ILI2510, with 10 years guaranteed availability
• USB/I²C interface/Optional UART
• Supports cover glass thickness up to 15mm
• Supports double gloves operation – not only nitrile –even double thicker gloves
• Working with water on the surface
• Multi-touch, up to 5 fingers
• Great EMC, RS (radiated susceptibility) and CS (conductive susceptibility) performance
• Touch performance could be easily tuned to fit specific needs

Optical / Air Bonding

Enhancing the optical performance of your display

Optical bonding is a process of affixing the touch panel (or just the protective glass) to the display using a liquid adhesive, gel or dry (film). In general, this process improves the parameters of the module – the optical performance, as well as durability.

The air-gap is the reason for the phenomena of reflection of sunlight. So, when the display is off, the Visual Area (V.A) is never black – it is gray.

When removing the air gaps, we reduce the number of internal reflecting surfaces, which increase of optical performance. This phenomenon improves readability, by reducing the reflection and correct contrast.

Customized displays

You can customize displays in many different ways.

• Change the color, shape, and size of the cover glass
• Have your logo printed on the cover glass (or any other graphics you might need)
• Add a different interface
• Enhance the brightness of the screen
• Change the thickness of the cover lens for the CTP
• Choose a different viewing angle of the display
• Change the pinout
• Request different gasket assembly

As you can see the possibilities are endless. All you need to do is choose.
