Stanley Electric was showing a number of projection technologies based on MEMs technology (W-400 device) and also on its LCDs. The first we looked at was a MEMS-based laser scanning mirror device that is driven by a piezoelectric drive mechanism with horizontal and vertical movement and capable of 36kHz horizontal scan and with reflectance of 95%. The module was small, but staff couldn’t tell us the dimensions or cubic capacity. Specifications were vague, but Stanley is interested in talking to partners for application development. Given the bright surroundings, the performance looked good. The use of lasers, of course, eliminates the need for focusing.

The company also had a system that is designed to be more of a spotlight, rather than a display. The angle of the spotlight can be controlled from 3º to 40º with intensity varying from 500 cd/m² to 100,000 cd/m². It can be used as a security light or can be used as an emergency or warning lamp.
We also had a look at a HUD system that was being shown based on an LED-backlit LCD using Stanley’s Pure Black Technology (PBTP) which is a high contrast passive segment display with peak contrast of 600:1. The display had an 864 x 480 resolution display with up to 34,000 cd/m² of brightness available. It uses a field sequential illumination system using a single imager and RGBW LEDs.
Stanley said that the panel could be used with a 300K cd/m² backlight (although up to 1 million cd/m² is under development) and that the mono module uses 1.5W in its 1.2″ form. Devices up to 1.8″ are under development.
