| (54) | Electromagnetic display panel |
| (57) A novel construction, of an electromagnetic display, which allows for the significant
reduction of the fabrication costs is described. The construction is adapted to a
batch processing of the electromagnetic display panel pixels (P), which can optionally
use novel electromagnetic driving as well as illumination concept. According to the
described construction concept the display pixels (P) are integrated into smaller
functional groups - segments, within which all static parts of the display pixels
are joined in a monolithic block (1), which can be mass-produced in an automatic process.
Due to the monolithic design the number of constituent parts is reduced to minimum
and the mechanical tolerances can be kept tighter. This in turn allows the other operations
like solenoid (5) winding, pixel flaps (2) insertion, contacting/mounting pins (4a
+ 4b) injection, etc to be performed simultaneously for all pixel elements joint in
the said basic display segment. The described display panel design also applies a
novel concept of display pixel illumination in low ambient light conditions based
on the use of UV light luminescent paints replacing the discrete pixel illumination
by light sources associated with each display pixel (for example: LED,...) as well
as novel electromagnetic display pixel driving, reducing the crosstalk between neighboring
display pixels based on the use of plasto-magnets built-in in the display flaps during
the injection molding production process.
