CAPACITIVE DISPLAY
2. Capacitive display
A high-quality 7” TFT true-color display with a capacitive touch
panel is the most distinctive feature of the mikromedia 7 HMI.
The display has a resolution of 800 by 480 pixels, and it can
display up to 16.7M of colors (24-bit color depth). The display
of mikromedia 7 HMI features a reasonably high contrast ratio
of 500:1, and brightness intensity of 420 Cd/m2, thanks to a
matrix of 9 x 3 high-brightness LEDs (27 in total) that are used
for backlighting.
The display module is controlled by the FT813 graphics driver
IC from FTDI. This is a powerful graphics controller targeted
at embedded applications to generate high-quality Human
Machine Interfaces (HMIs). It also includes some advanced
features such as the embedded video engine, enhanced sketch
processing, built-in synthesizer, and more.
The capacitive multi-touch panel, based on the FT5426 CTP
controller, allows the development of interactive applications,
offering a touch-driven control interface. The touch panel
controller uses the I2C interface for the communication with
the host controller. This advanced multi-touch panel controller
supports gestures, including zoom and swipe in all four
directions.
Equipped with high-quality 7” display (1) and the multi-touch
controller that supports gestures, mikromedia 7 HMI represents
a very powerful hardware environment for building various GUI-
centric Human Machine Interface (HMI) applications.
