“How many pixels are really needed for immersive visual
experiences with a virtual reality (VR) head-mounted display (HMD)?” This is
one of the most popular questions that I got during and after the short course
I taught at this year’s Display Week.
So I thought I would reflect over this a bit, and point to
some recent developments and trends in the display industry as gleaned from the
presentations and demonstrations at this year’s event.
First, let’s consider some basic, back-of-an-envelope, math
and calculations. Here are some facts related to the human visual system. An
ideal human eye has an angular resolution of about 1/60th of a degree at the
central vision. Each eye has a horizontal field-of-view (FOV) of ~160° and a
vertical FOV of ~175°. The two eyes work together for stereoscopic depth
perception over ~120° wide and ~135° high FOV.
Since the current manufacturing processes for both the
liquid-crystal displays (LCDs) and organic light-emitting diode display…

The digital signage (DS) sessions at Display Week opened
with discussions of the market aspects of the technology, then followed with implementations
of the displays. Conclusions were that display innovations will grow the DS market
over a billion dollars annually in just two years.
The target markets now and in the future are overwhelming. Business
and technology solutions worldwide discussed at Display Week included: Sports venues and public arenasVegas and gaming (sports books and entertainment)Transportation (trains and planes)Government (command, control, communications, and information)Retail and digital out
of home (DOOH)Corporate and conferencingInteractive and AR entertainment performers in the AR environment
with huge audiencesCinema (to replace DLP projection)
The current billions of sales in DS display solutions are
largely unknown to many in the industry. Signage includes the special (and
often artistic) implementation of LCD panels, LCD tiled walls of hu…

The SID Symposium and Exhibition part of Display Week opened
this morning with a strong set of keynote presentations. Paul Peng, Chairman
and CEO of AU Optronics Corp., started off the keynote session with AUO’s view
of past, present, and future display technology directions. He used Chinese
history as an analog of the progression of the display industry, with periodic
new “kingdoms” forming and merging, dominating, breaking up, and re-aligning.
His focus, understandably, was TFT LCD technology, since this represents the
majority of AUO’s portfolio. He gave an overview of AUO’s TV and automotive
applications and the advantages, from a “green” perspective, of the TFT LCD
manufacturing process over that of OLED displays. In fact, he seemed a bit
dismissive of OLED technology in general, consigning it to the “niche” applications
of mobile, wearable, and eyepiece displays.
The second keynote was given by Clay Bavor, VP of Virtual
Reality at Google. His presentation was polish…
