Design of LED Display Control System Based on AT89C52 Single Chip Microcomputer
This paper introduces display design process about hardware and software based on AT89C52 single chip microcomputer. We use a simple external circuit to control the display screen, which size is 32 × 192. The display screen also can display the size of the six 32 × 32 dot matrix Chinese characters by a dynamic scan mode, and can be divided into two small display screen, which can display twenty...
متن کاملDesign of a Wearable Tactile Display
Tactile displays are a viable way for people to interact with wearable computers. Human tactile perception is robust. A variety of shrinking tactile stimulator (tactor) technologies are available. Tactile displays are uniquely appropriate for wearable applications because of their close proximity to our 20 square feet of touch receptors: our skin. Tactile displays can solve issues of intrusive ...
متن کاملLED brightness control for video display application
The technique is suggested for a kind of pulse-width-modulation LED dimming in LED video displays. The significant increase of the gray levels number and image refresh frequency can be achieved when the large number of LEDs is controlled serially. The need for a large number of grayscale levels and high refresh rate is explained. The controlling data flow and the amount of buffer memory are the...
متن کاملDesign of a wearable wide-angle projection color display
In this paper, we investigate the design and fabrication of ultra-light weight projection lenses for color wearable displays. Driven by field of view requirements from 40 degree to 90 degrees, we employed the combination of plastic, glass, and diffractive optics to yield <10g optics per eye. The approach centers on the use of projection optics instead of eyepiece optics to yield most compact an...
متن کاملController Design for a Wearable, Near-Field Haptic Display
In this paper, we address the problem of providing near-field haptic feedback in a wearable, scalable manner. Our solution, called the TactaBoard, supports the independent control of 16 outputs on a single controller board using a standard serial port. We have tested the system with several types of output devices, including low-cost pager motors and fans. Based on Pulse-Width Modulation, the s...
