Mobile Rugged Displays for Situational Awareness

  • Magazine Article
  • TBMG-35280
Published 2019-10-01 by Tech Briefs Media Group in United States

With the constant emergence of new display technologies in the consumer sector, it is important for program managers and engineers in the military markets to be aware of how several of these advances can be incorporated into new military programs to achieve maximum benefit. Additionally, as older programs present themselves for technological refreshes, it is imperative to understand the difference in display specifications from previous decades and how updated technology provides avenues for their evolution and continued progress.

How HMI displays impact operator productivity in industrial vehicles

SAE Truck & Off-Highway Engineering: October 2019

The latest research indicates that well-integrated HMI (human-machine interface) systems lead to more attentive users that better retain task-related information and stay focused for longer with less reported effort. These systems also fit into the wider development trends in off-highway machines that affect operator fatigue in day-to-day tasks.

Photometric and Colorimetric Measurement Procedures for Airborne Electronic Flat Panel Displays

A-20A Crew Station Lighting
  • Aerospace Standard
  • ARP4260B
  • Current
Published 2019-09-17 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical performance of airborne electronic flat panel display (FPD) systems. The methods described are specific to the direct view, liquid crystal matrix (x-y addressable) display technology used on aircraft flight decks. The focus of this document is on active matrix, liquid crystal displays (LCD). The majority of the procedures can be applied to other display technologies, however, it is cautioned that some techniques need to be tailored to different display technologies. The document covers monochrome and color LCD operation in the transmissive mode within the visual spectrum (the wavelength range of 380 to 780 nm). These procedures are adaptable to reflective and transflective displays paying special attention to the source illumination geometry. Photometric and colorimetric measurement procedures for airborne direct view CRT (cathode ray tube) displays are found in ARP1782. Optical measurement procedures for airborne head up displays (HUDs) can be found in ARP5287. Generally, the procedures describe manual single point measurements. The individual procedures may be readily incorporated into automated testing equipment…

Flight Deck Lighting for Commercial Transport Aircraft

A-20A Crew Station Lighting
  • Aerospace Standard
  • ARP4103A
  • Current
Published 2019-09-17 by SAE International in United States
This document recommends design and performance criteria for aircraft lighting systems used to illuminate flight deck controls, luminous visual displays used for transfer of information, and flight deck background and instrument surfaces that form the flight deck visual environment. This document is for commercial transport aircraft except for applications requiring night vision compatibility.

Double-Sided Si(Ge)/Sapphire/III-Nitride Hybrid Structures

  • Magazine Article
  • TBMG-34888
Published 2019-08-01 by Tech Briefs Media Group in United States

NASA Langley Research Center has developed a double-sided Si(Ge)/ Sapphire/III-Nitride hybrid structure. This technology uses both sides of a sapphire wafer to build device structures — on one side, making either Si or SiGe devices and on the other side, making III-Nitride device structures (e.g. GaN, InGaN, AlGaN).

Laser Diode Based on Organic Semiconductors

Published 2019-07-01 by Tech Briefs Media Group in United States

Researchers have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, healthcare, and optical communications.

Self-Powered, Washable, Wearable Displays

  • Magazine Article
  • TBMG-34632
Published 2019-06-01 by Tech Briefs Media Group in United States

Clothing usually is formed with textiles and has to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. To solve this problem, a textile-based, wearable display module technology was developed that is washable and does not require an external power source.

Bendable Electronic Paper Displays a Range of Colors

  • Magazine Article
  • TBMG-34382
Published 2019-05-01 by Tech Briefs Media Group in United States

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It does not light up like a standard display, but rather reflects the external light that illuminates it; therefore, it works very well where there is bright light such as sunlight, in contrast to standard LED displays that work best in darkness. At the same time, it needs only a tenth of the energy that a Kindle tablet uses, which itself uses much less energy than a tablet LED display.

Evaluation of Different ADAS Features in Vehicle Displays

University of Michigan-Abhishek Mosalikanti, Pranove Bandi, Sang-Hwan Kim
Published 2019-04-02 by SAE International in United States
The current study presents the results of an experiment on driver performance including reaction time, eye-attention movement, mental workload, and subjective preference when different features of Advanced Driver Assistance Systems (ADAS) warnings (Forward Collision Warning) are displayed, including different locations (HDD (Head-Down Display) vs HUD (Head-Up Display)), modality of warning (text vs. pictographic), and a new concept that provides a dynamic bird’s eye view for warnings.Sixteen drivers drove a high-fidelity driving simulator integrated with display prototypes of the features. Independent variables were displayed as modality, location, and dynamics of the warnings with driver performance as the dependent variable including driver reaction time to the warning, EORT (Eyes-Off-Road-Time) during braking after receiving the warning, workload and subject preference. The primary results were in line with previous research, validating previous claims of the superiority of HUD over HDD in warning delivery. It was also found that the text format of the warning yielded higher response rates along with lower workload, while most participants preferred the dynamic bird’s eye view layout.
