Axi-Vision Camera (real-time distance-mapping camera)

The camera described here makes color TV images that include information about the distance between the camera and the objects in the images. This range information is obtained from two images of the same scene taken under different illumination conditions. The camera does not require scanning, multiple camera units, or complicated computation. Range information for each pixel is acquired fast enough to keep up with the video rate of a TV camera. We describe various operational features and technical specifications such as ranging errors as well as the results of experimental investigations of the dependence on the color and reflectivity of the objects, of the sensitivity to interference from external light, and of the effects of the movement of the objects.

16.4: Low‐Temperature Fabrication of Flexible AMOLED Displays Using Oxide TFTs with Polymer Gate Insulators

We have developed InGaZnO4 TFTs with polymer gate insulators that can be formed by spin-coating on plastic substrates at temperatures below 130 °C. A 5-inch QVGA flexible OLED display has been fabricated by means of ink-jet printing on a TFT backplane, and it has successfully displayed clear color video images while in a bent state.

10.4: Fast‐Response Flexible LCD Panel Driven by a Low ‐Voltage Organic TFT

A fast-response flexible ferroelectric liquid crystal (FLC) display panel driven by organic TFT (OTFT) was successfully developed. The fabricated OTFT with Ta2O5 gate insulator showed a mobility of 0.3 cm2/Vs and a current on/off ratio of 107 with a low operating drain voltage of −5 V. We obtained fast responses of less than 1 msec and contrast ratio of 14:1 with gray-scale display capability from a 16×16 pixel FLC panel.

23.3: Flexible Field‐Sequential‐Color FLCD Panels Driven by poly‐Si TFTs

A novel flexible field-sequential-color FLCD panel driven by poly-Si TFTs has been developed. A 16×16 active matrix panel was fabricated using polymer stabilized FLC and poly-Si TFTs fabricated onto plastic substrate below 150°C, and colored moving images were demonstrated on the panel with frame frequency of 60Hz.
