Technologies For Enabling Versatile Information Display

Mphepo, Wallen (2016) Technologies For Enabling Versatile Information Display. Doctoral thesis, University of Sunderland.

Item Type: Thesis (Doctoral)


The thesis work is centered on five objectives. These objectives are among
the main factors in the field of electronic information display technologies.
They are namely display optical efficiency, crosstalk, resolution, power
consumption and switchable 2D/3D capability.
The thesis findings and the different levels of success are covered in detail in
chapters 4 through chapter 8. They are then summarized in discussion and
conclusion chapter using measurable quantities in tabular format.
Specifically, with respect to optical efficiency three different solutions were
applied. The first raised optical efficiency by 60%. The second solution
raised optical efficiency to 90%. The third solution eliminated the need for
backlighting altogether as well as remove pixel circuitry from optical light
path. With respect to image crosstalk, two solutions were applied. One
method reduced crosstalk by 51% while the other method eliminated
crosstalk to zero percent in the viewing zones. With respect to resolution two
methods were applied. One method increased 3D display resolution by
limiting the reduction of the native display resolution by only half regardless
of the number of concurrent 3D viewers. The other method increased display
resolution 900%. With respect to power consumption two methods were
applied. The first method eliminated the need for backlighting and also
reduced the number of thin film transistors [TFTs] needed by 60% for the
same display resolution. The second method increased display brightness
by 60% without increasing power consumption. Finally with respect to 2D/3D
switchable display an optical module was designed that successfully enable
a conventional 2D display to become a switchable 2D/3D display.
