The RiTFT-35 is a high-quality Riverdi 3.5’’ TFT display module.
The 12:00 o’clock viewing angle allows the user a natural and intuitive way to interact with the display. The RiTFT-35 has a built-in LED inverter. For more information about the RiTFT-35 see the documentation section.
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.
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 fonts 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.
