Plenary Talk

Evolution of Automotive Displays and HMI: Past, Present, and Future

Peter Knoll

Bosch, Gerlingen, Germany

Thursday, June 4 

8.30 – 9.00am

In former times only a few gauges were necessary to survey a vehicle’s functions. Current and future concepts bundle the huge amount of information coming from new driver-assistance systems in three information centers: a reconfigurable instrument cluster and a head-up and a center console display in conjunction with appropriate operating techniques.

Development of RGBW LCD with Edge-lit 2D Local-Dimming System for Automotive Applications

Naoyuki Takasaki,
Japan Display, Inc. Ebina Japan

Thursday, June 4 / 9.00-9.20am

A 10-in. RGBW LCD with an edge-lit 2D local-dimming backlight system for automotive applications has been developed. This prototype system exhibits a reduction in power consumption of 41.5% compared to that of a conventional RGB display without a local-dimming backlight. The performance and evaluation results will be described.

High-Reliability Integrated Gate Driver Circuit in a Panel for Automotive Displays

Dayhe Shim

LG Display Co., Ltd., Gyeonggi-do, South Korea

Thursday, June 4 / 9.20-9.40am

Automotive displays require high reliability for long-term usage and a wide operation temperature range. A new a-Si:H integrated gate driver circuit, where the self-compensation transistors are intentionally added to stabilize the bias conditions at the extreme environment, is proposed. This improves the reliability of the automotive display.

Invited Paper: Megatrends Driving Automotive Displays and Associated Mega Issues

Paul Russo

GEO Semiconductor, Inc., San Jose, CA, USA

Thursday, June 4 / 9.40-10.00am

The accelerating growth in the use of advanced electronic safety, convenience, and semi-autonomous driving systems in automobiles will generate massive amounts of information that must be conveyed to drivers. Displays are evolving rapidly to provide this information in safe and efficient ways. Automotive displays will increasingly resemble airplane cockpits. From reconfigurable large-area high-resolution LCDs to HUD systems offering increasing content while the drivers’ eyes remain focused on the road, new classes of displays will become the norm to allow drivers to easily absorb the critical information being generated. Challenges associated with these display transitions will also be discussed.

41.4:

Invited Paper: Future Car  HMI Innovations

IP Park

Harman International,

Stamford, CT

Thursday, June 4 / 10.00-10.20am

There will be more and more computers in cars: built-in, brought-in, worn, etc. These computers want to interact with us (and we with them). If not designed and engineered appropriately, the user interfaces between us and these computers will become more complex—and more distracting.

What is needed is careful attention to the interaction methods, or HMI.

Changes to the HMI cannot be just incremental, but have to be dramatic.

This talk will cover recent developments that can be game-changing for  in-car HMI.

47.1:

Invited Paper: Practical Application of TI DLP® Technology in the Next-Generation Head-Up Display System

Jason Thompson

Texas Instruments, Plano, TX, USA

Thursday, June 4 / 10.40-11.00am

Next-generation automotive head-up displays (HUDs) could fundamentally change how OEMs utilize the HUD. A significantly larger virtual display area and vastly improved image quality are two of the many benefits. Along with the benefits come a unique set of challenges, which can be addressed by incorporating TI DLP® solutions. Options for these challenges, including the comparison of different solid-state illumination sources, have been explored, and practical solutions for developers will be offered.

47.2:

Invited Paper: Laser-Scanning Head-Up Display for Better Driving Assistance

Koichiro Nakamaura

Ricoh Co., Ltd., Yokohama, Japan

Thursday, June 4 / 11.00-11.20am

As advanced driving-assistance systems pervade automobiles, drivers are exposed to more information than ever before. Head-up displays are expected to provide the necessary contents depending on necessity and urgency. The promises and challenges of the technology will be discussed.

47.3:

Invited Paper: World-Fixed Augmented-Reality HUD for Smart Notifications

Mainak Biswas

Qualcomm, San Diego, CA, USA

Thursday, June 4 / 11.20-11.40am

A head-up display (HUD) system that displays perspective-correct surrounding information for driver safety will be presented. In the implementation, contrast-enhanced ego lane information on the HUD is displayed during driving conditions with poor visibility. The use of HUD for augmented-reality (AR) needs an accurate model of the picture-generation process for proper visualization of the 3D content that is perspective accurate from the user view point. The system uses multiple computer-vision techniques for the accurate visualization.

47.4:

A Novel Full-Windshield Heads-Up Display (FWD) Technology

Ted Sun

Sun Innovations Inc Fremont ,CA USA

Thursday, June 4 / 11.40-12.00pm

Sun Innovations has developed a full-windshield head-up display (FWD) system for automotive applications. This revolutionary display device is based on a projection-based fluorescent display (PFD) technology which is a new concept of forming full-color and emissive images on an optical clear and fluorescent substrate by projecting light at multiple UV/blue wavebands. With the FWD, information such as GPS navigation signs, on-road obstacles detected by a night-vision camera, warnings from on-board sensors, as well as many other types of mission-critical information can be graphically displayed anywhere on the windshield without any limitation of view angles. FWD will also enable advanced augmented-reality applications over the entire windshield.

Taiki Kasai

Japan Display, Inc., Tokyo, Japan

Thursday, June 4 / 1.30-1.50pm

A 10.0-in. 1080 × 2880 capacitive curved-faced prototype LCD for automotive use, which has integrated in-cell touch panel technology, will be described. A sufficient signal-to-noise ratio of 100–160 was achieved with this display despite the 1.1-mm-thick cover glass.

Visual Search and Attention: What Eye-Tracking Reveals about Visual Performance in the Curved Display

Hyeon-Jeong Suk

KAIST, Daejeon, South Korea

Thursday, June 4 / 1.50-2.10pm

For flat and curved displays, the subjective impressions of quality were measured, and the eye gaze to a variety of video content was tracked.  There was a subjective preference for curved displays, but eye-gaze analysis revealed no statistically significant differences in number or duration of eye fixations.

Invited Paper: Creating a Compelling Touch Experience

Chad Sampanes

Immersion Corp. San Jose, CA, USA

Thursday, June 4 / 2.10-2.30pm

Car infotainment systems now offer a larger variety and a more complex set of use cases than ever. Haptics have the potential to improve safety, utility, and user experience of these touch-based systems. Some of the design issues will be covered, and how to create compelling haptic experiences will be discussed.

Metal-Mesh Design For High-ppi LCD Application

Chun-Chi Chen

Gerneral Interface Solution, Ltd., Miaoli, Taiwan, ROC

Thursday, June 4 / 2.30-2.50pm

Metal-mesh technology offers low RC loading in touch panels and curved touch LCDs, as well as low cost. For high-resolution displays (>530 ppi), moire patterns due to interference with the TFT-LCD can be a significant problem. Methods to solve the visibility issue of moire patterns for touch displays, including curved touch LCDs, will be described.

Hidefumi Yoshida

Sharp Corp., Nara, Japan

Thursday, June 4 / 3.10-3.30pm

A new stylish TFT-LCD has been developed, where gate-driver monolithic circuits were placed in the pixel area. Because there are no electronic circuits in the frame area, a narrow border and round corners or a multi-concave shape can be simultaneously realized.

Highly Stable and Transparent Oxide TFTs for Rollable Displays

Jin, Jang

Kyung Hee University Seoul South Korea

Thursday, June 4 / 3.30-3.50pm

Highly stable oxide-TFT circuits with a visible-light transmittance of ~70% and rollable to cylinders with a radius of 2 mm were demonstrated on solution-processed colorless polyimide. Carrier glass and a special de-bonding layer were used during fabrication. Stable TFT and circuit performance were achieved under positive-bias and mechanical bending stress.

Functional Transparent Coatings for Displays

Songwei Lu

PPG Industries, Inc., Allison Park, PA, USA

Thursday, June 4 / 3.50-4.10pm

Optical functional coatings have been spray deposited onto a pre-treated glass surface followed by a low-temperature curing at 150°C. Such coatings exhibit excellent steel-wool wear durability and low coefficient of friction. The coating has gloss values between 50 and 100, pencil hardness > 8H, and exhibits no sparkling.
