SID - Society for Information
Display
•
From Osaka to Eindhoven, you will find colleagues passionately
involved in display and display-system design, integration, marketing,
display standards, manufacturing, human factors, applications, and
R&D.
•
The 6000 members of SID are professionals in all of the technical and
business disciplines that relate to display research, design,
manufacturing, applications, marketing, and sales. SID invites you to
join us in developing and manufacturing the displays for the 21st
century, and applying them to exciting information, telecommunications,
medical, commercial, government, entertainment, and consumer
products.

SID - Society for Information
Display
•
There are 12 local US chapters (Major area LA, Bay Area, NW, NE….)
with monthly meetings in three regions (Americas, Europe and Asia).
•
The US and Europe have many aerospace and systems companies
and many Asia companies provide display components and
manufacturing.
•
The Annual International Symposium and Exhibits are in the US on the
West or East coast. The 2008 Symposium will be at the LA Convention
Center in May.
•
The SID LA Chapter has had joint meetings with SMPTE where topics
of common interest are covered.

LCD Improvements
• Viewing angle
• Response time
• Backlight life
• Larger sizes
• Higher resolutions
• Power reductions - achieved by dimming the backlight based on
content
• Contrast improvements - achieved with local dimming of LED
backlights
• Motion blur - by increase refresh rate of the panel at 120hz
• Color gamut - can be increased with RGB LED backlights

Motion Blur
• What is Motion Blur?
– Motion Blur is an artifact on a display when motion
like a panning of a camera or scrolling of a picture
as view by the eye.
– The blur is at an intensity transition. Blur is caused
by the LCD response time and hold type drive of
panel.

Motion Blur
• To reduce Motion Blur the backlight at pulsed at 60 Hz but at
reduce brightness
• Driving the panel at 120 Hz with an interpolated frame is used
without the reduce brightness.

OLED Displays
• Sony has started a limited production of am 11” OLED TVs
in December and demonstrated a 27” panel at CES
• Samsung has also demonstrated 14” and 31” panels
produce very impressive picture quality
• Organic LED displays are emissive were there is not
backlight and can produce products that are very thin or
flexible. OLED displays have been used in cell phones and
cameras
• There are many mass production and life issues that must
be resolved before OLEDs will be a serious contender with
LCDs

Sony in a statement issued in Tokyo said it began mass
production of the XEL-1 in September. The company has been
selling OLED panels for mobile phones since 2004. The first
TV to go on sale in Japan will be an 11-inch model with a
screen 3 millimeters thick, The Wall Street Journal reported.
The set would cost about $1,700.
OLED screens have brighter pictures, higher contrast, and
better color than seen on today's LCD and plasma screens,
analysts say.
