OLED Broadcast Monitors
T

he two main display technologies
in widespread use in the broadcast
industry today are LCD & OLED.
While LCD's work by filtering an
overall backlight, OLED panels are
made of an array of individual RGB
light sources. For an HD OLED we see
over two million light sources, while
for UHD the figure is nearly 8.3 million.
The key advantage of OLED displays
is that black is an absence of light,
meaning black is a true black. The
response times of OLEDs are generally
faster than LCD with a consequent
lack of smearing in panning shots
and fast moving images. It is not
a slam-dunk for OLED technology
however. LCDs can provide higher
peak brightness, up to
2,000nits and combined
with locally dimmable
backlights, LCDs can
provide contrast rations
of up to 1,000,000:1.
These figures become
key when we look at high
dynamic ranges or HDR
monitoring.

TVLogic introduced the very first
OLED broadcast monitor at NAB 2010,
promptly followed by the first 3D OLED
broadcast monitor. The 2D version,
the LEM-150, proved popular with jib
operators, who liked the compact size
and fast response. It was also popular
in galleries, where the true black levels
made it ideal for racking cameras.
This was followed by the LEM-250A,
a 24-inch full spec. grading monitor,
which had the option of 12VDC
battery power, also making it an ideal
monitor for high-end production

location monitoring. The
monitor is based on a
Sony OLED panel, also
used by a number of other
manufacturers.
TVLogic's latest 5.5inch OLED viewfinder
monitor VFM-055A had its
European launch at IBC this
year. The high contrast ratio and quick
response of the OLED panel make it
ideal as a camera top monitor. The
addition of colour peaking to aid focus
and zebra for correct lighting make
this monitor a must have for focus
pullers. TVLogic have used traditional
buttons and switches to control the
monitor as the capacitive filters used

VFM-055A

on touch screens can cause colour
degradation and the screen can show
the fingerprints.
TVLogic also showed the LEM-550R
for the first time at IBC 2017. This
55-inch OLED HDR QC grade monitor
offers a combination of 750nits
peak brightness, a contrast ratio of
150,000:1, and a wide colour gamut
to support REC-709,
DCI-P3 & REC-2020 via
TVLogic's 10-bit colour
processing engine. It is
expected to ship early in
January. This will follow
the launch of TVLogic's
2,000nit HDR LCD in
December. LCD is still
alive and well.
