by The Editorial Staff
THE SID 2008 International Symposium, Seminar, and Exhibition will be held at the Los Angeles Convention Center in Los Angeles, California, the week of May 18. For 3 days, May 20–22, leading manufacturers will present the latest displays, display components, and display systems. To present a preview of the show, we invited the exhibitors to highlight their offerings. The following is based on their responses.
3M is demonstrating how its Vikuiti™ optical films lower LCD energy consumption by 30% or more. On display will be a 70-W 32-in. LCD TV and a 20-W19-in. monitor that uses only two CCFL bulbs. Visitors can see both LCDs adjacent to identical models with and without Vikuiti brightness-enhancement films. The LCD TV without Vikuiti optical film requires 122 W to deliver equal brightness. The monitor without Vikuiti films requires four CCFL bulbs and 30 W to deliver the same brightness.
Touch is becoming the standard interface for mobile devices. 3M Touch Systems and MicroTouch™ TPC1000 touch sensors (formally known as Flex Capacitive) can help bring ideas to reality. 3M's experience in developing button, analog X,Y and multi-touch sensors can help speed new product introductions into the increasingly competitive mobile-handheld-device market. TPC1000's thin touch sensor enables sleeker device formats while index-matching capability maintains the brightness and true color of the LCDs.

A new line of LED-backlit LCDs, which are sunlight readable for daytime use, and also offer NVIS capability, will be introduced. These edge-lit LED solutions offer at least a 2:1 improvement over stock CCFL backlights for panels up to 18 in. on the diagonal, which means that system designers can expect to double the brightness for the same amount of power consumed.
Integrated technology demonstrators
General-purpose integrated technology demonstrators for the military utilizing low-power flexible-display technology, including the Soldier Flex Personal Digital Assistant (SF-PDA) produced with InHand Electronics and FDC member E Ink, and the Mission Briefer produced with FDC member General Dynamics. Both demonstrators incorporate high-performance daylight-to-moonlight–readable 3.8-in. QVGA electrophoretic displays fabricated using FDC's low-temperature a-Si:H TFT pilot-line process and E Ink's Vizplex imaging film. The combination of the intrinsically rugged low-power display with system-level electronics design and effective power management results in dramatic decreases in size, weight, and power (SWaP) compared to situational-awareness military products currently available.

In-cell multi-touch panels
AUO has launched two 4.3-in. multi-touch technologies: Voltage-Sensing and Charge-Sensing types. AUO's in-cell multi-touch technologies integrate touch-function features into the TFT-LCD manufacturing process without adding additional glass, and thus are able to retain a thickness of 2.2 mm – thinner than conventional touch-panel applications. Also, they both have superior anti-glare properties to retain proper image color saturation and readability under sunlight conditions. Targeted to enter mass production in mid-2008, the two newly introduced AUO in-cell multi-touch panels are claimed to be the world's first mass-produced in-cell multi-touch panels.
Conoscopic systems are colorimeters that capture the complete viewing-angle range in a single image. The ConoScope features a color (measurement) camera with a conoscopic lens for ultra-rapid measurement, requiring less than 1 sec to perform a full-viewing-cone measurement for luminance and color up to a viewing angle of 88°. A further benefit of this combination of color camera and conoscopic lens is the "live preview," a real-time display of the color and luminance for the complete viewing cone. Further unique features include switching time and gray-to-gray measurement using an integrated photomultiplier. The diffuse reflective illumination enables full-viewing-angle characterization of reflective displays. The unique focal-plane stage features BRDF measurement and provides an interface for spectro-radiometer connection.
Axometrics's new high-speed AxoScan™ Panel Mapper (APM-60H) completely characterizes any type of LCD panel (TN, STN, VAN, IPS, OCB, etc.) up to 60 in. on the diagonal, providing measurements for cell gap, twist-angle, rubbing direction, and front and back pre-tilt angles. The APM measures the complete polarization properties (full Mueller Matrix) of the panel while adjusting the XY coordinates, azimuth angle, polar angle, and spectral wavelength. These measurements are then used by Axometrics's patented LCDView™ software to quickly and accurately calculate the panel's parameters. In addition to LCD panels, the polarization properties of other materials may be measured, including polarizer films and retarder films (A-plates, O-plates, and c-Plates).
Shielded cables for flat displays
Axon' Cable adds shielded assemblies for LVDS interfaces to its line. Named AXOLINK®, these flat cable assemblies include DF-19 (Hirose) and FI/FI-X (JAE) connectors. Other connector types are also available. The shielding is carried out with a ground plane grounded on the connector, thus assuring a constant impedance of 100 Ω for a very stable picture transmission. These cables are able to work at up to 1 Gbit when terminated with the appropriate connectors.
The BigByte BB-2000 burn-in chamber provides continuous closed-loop monitoring of both temperature and humidity, providing accurate control of the internal environment.

BriteView's backlight system uses a beam expander and a light guide to achieve dual-mode illumination using LEDs as the light source. In this backlight, only two LEDs are used for NVIS-mode operation. With this novel backlight system, a uniform illumi-nation is maintained even when one of the two LEDs for the NVIS-mode failed. This backlight can also provide a reasonably uniform illumination even when some of the LEDs for the day mode failed. With a single light guide to provide the dual-mode operation, this backlight is compact and highly efficient.

High-resolution laser inspection system
Dark Field/Jenoptik have developed and proven telecentric laser inspection systems, which deliver multiple optical channels in an optically elegant system. A single-laser scanner provides a spot of laser light that scans the film or glass, at a constant angle (telecentric scanning). All critical optical information is extracted from the transmitted and reflected beams concurrently. This means that all information extracted from the product is spatially coincident; no other system can deliver this performance. This technology has been proven in a wide array of inspection applications including brightness-enhancement films, polarizing films, etc.
ExpertLCD provides a complete physically based simulation environment. It can estimate not only liquid-crystal dynamics and optics but also electrical properties of liquid-crystal displays.

Recently, several functions have been developed, such as full electromagnetic solver for analyzing light such as around a black matrix, a tensor solver for OCB, full-screen simulation for multi-image, and structure emulator for real LCD fabrication.
Adhesives for the sealing of OLED displays
DELO Industrial Adhesives has recently developed highly efficient OLED sealants. OLEDs consist of a self-lighting array of semiconducting layers, which in turn consist of organic substances reacting sensitively to humidity and oxygen. Therefore, the component is encapsulated between two glass plates. For this purpose, light- or UV-curing adhesives with an extremely low permeation for oxygen and humidity are used. Furthermore, the adhesive adheres to glass and is suitable for fast and automated high-volume processes. The reason is that OLED encapsulation compounds do not require thermal postbaking but are cured by light, resulting in short processes and cost savings.
Delta's ICAM is a filter-based high-accuracy 2-D colorimeter that measures absolute color and luminance on both still images and moving images. Parameters such as uniformity in color and luminance, contrast ratio, color gamut, and mura effects are measured at a glance.

Wide-screen projected capacitive touch sensors
Zytronic's recently launched large-format XY controller for its Projected Capacitive Technology (PCT™) touch sensor products offers greater flexibility for a range of LCD types, including popular wide-screen displays. The new controller includes additional functionality such as palm rejection, and enables accurate touch detection through up to 10 mm of protective cover glass for 4:3 and now 16:9 format screen sizes up to 65 in. on the diagonal. This controller supports a larger range of operating systems, including Vista and Linux, and coupled with the unique durability of PCT™ touch sensors, offers designers a robust solution for outdoor and public-access digital-signage applications. •
