truly backwards-compatible while benefiting from high-resolution AMLCD technology.
Built-in tests include SRAM and SDRAM pattern tests,
deflection, stroke intensity, raster A/D interface test, LCD
I/F status check, HDRIVE & VDRIVE period checks, and
a visual BIT display pattern.
While this signal type is unique for this particular
application, the FPGA configuration has many elements
that can carry forward to other designs.
Developing a custom LCD controller provides several
immediate benefits. The FPGA and support components
can be sized for only the necessary functions, which can
reduce size, weight, power, and cost (SWAP-C). This also
wards against cybersecurity, which has gained considerable
attention, by controlling the pedigree of a major logic-bearing component. The hardware can be placed and
routed on a circuit board outline that can better meet
the requirements of mounting, cooling, harness routing,
and maintainability. In many cases, this can reduce costs
and increase reliability by eliminating the need for the
LCD controller to be a separate circuit board, as the
video processing and LCD control can be co-located with
the microcontroller, which handles basic functions like
backlight intensity and bezel button actuation.
The resulting in-house development of the LCD
controller function provides a point of departure for more
flexible and complete solutions in future products at
only a delta cost. Features can be added and removed as
necessary. In this example, common digital video inputs
may be included as build options, and a DDC interface
may be used to automatically configure the output
characteristics to drive different LCD panels. FPGAs
