Touch Screen.

Well-suited for robust environments

TFT display module with a resistive touchscreen. These types of screens are well-suited for more robust environments. They have a high resistance to dust and other elements and they can be used even with gloved hands.

Resistive touch screens have low-power consumption and are suitable for battery powered devices.

BT81x (EVE 3)

A powerful graphics controller

If your project requires a more complex execution Bridgetek’s graphics controllers are the right choice. The BT81x controller on this display is a part of a family of advanced graphics controllers targeted at embedded applications for generating high-quality Human Machine Interfaces (HMIs).

Riverdi displays with BT81x graphics controllers feature advanced EVE (Embedded Video Engine) user interface, that successfully combines the capacities of processing images, sound, and information from the touch panel.

EVE technology uses an object-oriented approach; this whole controller series is capable of simplifying the implementation of intelligent displays and shortening development time, see the datasheet.

EVE3 Advantages

The third generation of Embedded Video Engine (EVE) technology brings us the BT81x graphics controllers with numerous improvements and extended capabilities.

One of the most prominent advantages, in comparison with the two older versions, is support for the Adaptive Scalable Texture Compression (ASTC) algorithm. This means image quality can be significantly enhanced without needing greater bandwidth to be allocated as the compression algorithm allows for smaller compressed files. This, in turn, saves up a lot of memory space required by larger s and data-heavy images.

Further memory management and system resource improvements are available in the form of a dedicated QSPI host port for attaching an external flash memory.
