Toshiba Mobile Display Company And Toshiba Corporation To Present Technical Papers At SID 2011

May 16, 2011

Seven Presentations Will Address Developments in AMOLED Displays, Touch Screen Sensors, Back Lighting and Other Technologies

LOS ANGELES, Calif., — Toshiba America Electronic Components, Inc. (TAEC),* announced that Toshiba Mobile Display Co., Ltd. (TMD)** and Toshiba Corporation R&D representatives will present seven papers addressing next-generation display technologies at the Society for Information Display (SID) Symposium, Seminar and Exhibition at the Los Angeles Convention Center in Los Angeles, California this week.

The presentation schedule for TMD and Toshiba technical papers is as follows:

Presentation 4.1: “Low-Temperature-Processed IGZO TFTs for Flexible AMOLED Displays with Integrated Gate Driver Circuits”

Session 4: Oxide TFTs I
Time and Location: Tuesday (5/17), 10:50am – 11:10am, Petree Hall C
Presenter: Toshiba Corp., Kawasaki, Japan
Synopsis: The threshold-voltage shift of 200ºC IGZO TFTs to 0.3 V (at Vg = 20 V, 90ºC, 2000 sec) was reduced by optimizing the IGZO deposition conditions. A flexible AMOLED display with integrated gate driver circuits has been demonstrated.

Presentation 19.4: “Novel Depth-Perception-Controllable Method of WARP under Real Space Conditions”

Session 19: Large-Area, Head-Up, and Rugged Display Applications
Time and Location: Tuesday (5/17), 4:40pm – 5:00pm, Room 408A
Presenter: Toshiba Corp., Kawasaki, Japan
Synopsis: A compact 2-liter monocular head-up display that is WARP-mountable on an automobile windshield has been developed. A novel depth-perception-controllable method is proposed and the depth-perception-enhancement characteristics under real-space conditions have been examined. It was confirmed that the depth perception was controlled as far as 60 m and true AR was achieved.

Presentation 43.4: “An In-Cell Capacitive Touch-Sensor Integrated in an LTPS WSVGA TFT-LCD”

Session 43: Capacitive Touch Systems
Time and Location: Thursday (5/19), 10:00am – 10:20am, Petree Hall D
Presenter: Toshiba Mobile Display Co., Ltd., Saitama, Japan
Synopsis: An in-cell capacitive touch-sensor integrated in an LTPS 7” WSVGA TFT-LCD. The prototype having 256x150 sensors shows advantages such as high position accuracy, multi-touch (10 or more), smooth operation with no touch force, thin and light LCD module, and thus is suitable for various applications.

Presentation 50.3: “Novel Write-Erasable Input Display with Memory Circuits and Photosensors”

Session 50: Optical Touch Systems
Time and Location: Thursday (5/19), 11:20am – 11:40am, Petree Hall D
Presenter: Toshiba Mobile Display Co., Ltd., Ishikawa, Japan
Synopsis: We have developed a new conceptual LCD with a memory circuit and a photo-sensor in each pixel. This LCD display enables a still image in a low power mode. In addition, by using a light-pen direct writing and erasing of a character on the LCD is possible without calculating coordinates.

Presentation 53.3: “New Light-Bar Emitting Phosphor-Converted White Line Light Pumped by InGaN/GaN Laser Diode for Edge-Lit Backlight-Unit Applications”

Session 53: LED and Laser Backlights
Time and Location: Thursday (5/19), 11:20am – 11:40am, Room 408A
Presenter: Harison Toshiba Lighting Corp., Ehime, Japan
Synopsis: A light bar for an edge-lit BLU pumped by novel InGaN/GaN laser diodes (LDs) at a wavelength around 400 nm has been demonstrated. Compared to an LED light bar, the LD light bar shows high thermal stability with a center luminance change of only 6.7%, and a chromaticity change (Dx, Dy) of (-0.001, +0.002).

Presentation 55.4: “Image-Processing-Based Cross-Talk Reduction for Stereoscopic Displays with Shutter Glasses”

Session 55: Crosstalk in Stereoscopic Displays
Time and Location: Thursday (5/19), 2:30pm – 2:50pm, Concourse Hall
Presenter: Toshiba Corp., Kawasaki, Japan
Synopsis: A crosstalk reduction method based on image processing for stereoscopic displays with shutter glasses is proposed. The proposed method precisely evaluates crosstalk caused by not only LCD responses but also backlight leakage and the response of the glasses. Experimental results show that the method reduces crosstalk by 70 percent.

Poster Session P.57: “Local-Dimming Algorithm to Minimize Maximum Luminance Reproductive Error”

Session 55: Display Electronics Posters
Presenter: Toshiba Corp., Kanagawa, Japan
Synopsis: A local-dimming algorithm that guarantees both low power consumption and higher reproducibility, even at lower luminance levels, will be described. A new objective function is defined to evaluate reproducibility both at higher and lower luminance.

1Based on MTBF statistical values. MTBF (Mean Time Between Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may not resemble the MTBF.

2Mercury-Free: Toshiba Mobile Display Co., Ltd. defines "Mercury-Free" products as those containing no more than a maximum concentration value of 0.1 percent mercury(Hg) by weight in Homogeneous Materials3. This does not mean that Mercury-Free products are entirely free of mercury(Hg).

3 Homogeneous Materials: Toshiba Mobile Display Co., Ltd. defines "Homogeneous Materials" to mean a material that cannot be mechanically disjointed into different materials. The term "homogeneous" is understood as "of uniform composition throughout," so examples of "Homogeneous Materials" would be individual types of plastics, ceramics, glass, metals, alloys, paper, board, resins and coatings. Toshiba Matsushita Display Technology Co., Ltd. defines the term "mechanically disjointed" to mean that the materials can, in principle, be separated by mechanical actions such as unscrewing, cutting, crushing, grinding or abrasive processes.
