mikromedia 7 CAPACITIVE U S E R M A N U A L
CAPACITIVE DISPLAY
3. Capacitive display
A high-quality 7” TFT true-color display with a capacitive touch
panel is the most distinctive feature of the mikromedia 7. The
display has a resolution of 800 by 480 pixels, and it can display
a true-color palette of 16.7M of colors (24-bit color depth). The
display of mikromedia 7 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 SSD1963 graphics
driver IC from Solomon Systech (1). This is a powerful
graphics coprocessor, equipped with 1215KB of frame
buffer memory. It also includes some advanced features
such as the hardware accelerated display rotation, display
mirroring, hardware windowing, dynamic backlight control,
programmable color and brightness control, and more.
Some of the display hardware options can be configured
by using SMD jumpers, located in the TFT section (2) of the
development board:
LR: Left/Right sequence control of source driver
UD: Up/Down sequence control of gate driver
DITH: Dithering function enable/disable
MODE: DE/SYNC mode select
Please note that the default settings match those in Mikroe
software toolchain, so it is not recommended to change
them from defaults.
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 MCU. This advanced multi-touch panel controller
supports gestures, including zoom and swipe in all four
directions.
Equipped with high-quality 7” display (3) and the multi-touch
controller that supports gestures, mikromedia 7 represents
a very powerful hardware environment for building various
GUI-centric Human Machine Interface (HMI) applications.
