A digital display panel accepts pixel information according to their
row-column coordinates. Each pixel can be individually written and read
back, much like a random access memory (RAM). A pixel array
self-refreshes, and can retain and display each image frame long after
the original writing, like a dynamic random access memory (DRAM). Each
pixel is instrumented with a transducer to sense pressure, temperature,
light, strain, etc., and provide sensor read-out data that is addressable
by row-column coordinates. Such is very useful in touchscreen
applications. The transducers and their corresponding pixels each have a
special relationship, the transducers can directly manipulate a visual
quality of the pixel through a direct connection, without intervention or
assistance by a host processor.
