In this paper, we would like to introduce a second generation of headlight glare simulator to be used with a driving simulator that significantly improves spatial and brightness accuracy of previously developed prototype headlight glare simulator (Fullerton & Peli, 2009). The system combined a programmable off–the-shelf LED display board and a beamsplitter so that the LED lights, representing h...

Abstract Widely used LED electronic displays have high requirements for power quality. Because of the status quo technology update and lack related experimental work, this paper first analyzes hardware composition display switching supply module. In addition, points out that transient tolerance screens is mainly determined by modules. Then, a test platform was built, certain type screen selecte...

This paper proposes a new architecture for micro light emitting diode (micro-LED) display featuring fingerprint detection without any additional and sensing devices in mobile applications. that conventional LEDs can be used as photodetectors active-matrix pixel circuits. In the area where finger touched, some are others sources. The photocurrents of reverse-biased under various illumination con...

In this paper, a design of LED display control system based on ARM and FPGA is proposed, according to module structure characteristics of the RGB three colors LED display and the dynamic scanning display of the LED display which is achieved by FPGA technology, this system uses ARM chip S3C2240 as the control core. with the help of the programmable logic device auxiliary, it completed the data s...

The main objective of this research was to develop a methodology based on Drury’s [1] intermittent illumination model to directly measure individuals’ corrective reaction times, without the two methodology-related issues of Lin & Drury [2]. Six highly-practiced participants performed self-paced circular tracking tasks by using a modified LED monitor in a darkened room. While performing movement...

The paper begins by discussing various approaches to hardware specification and verification. The main emphasis is on using mechanical verification tools to assist the verification process. The case study is the verification of a seven-segment LED display decoder circuit design, in which two popular verification tools, HOL and PVS, are compared and evaluated.

LED backlight for LCD is an emerging technology with vast performance potential compared to CCFL backlight. The key performance which directly impacts the consumer is the image quality on LCD screen. This paper will review some of the performance enhancements in image quality arising from LED backlight.

The digitization of clock has brought us enormous conveniences and the development of the special-purpose clock chip would extend the traditional functions of clock. In this article, we design a new calendar clock based on DS12C887 chip and AT89C52 SCM. The system includes 5 parts: the AT89C52 SCM module, the calendar clock module, the LED display module, serial communication module and the C51...
