Camera Phones Plaza

Combined Exhibition of Advanced Technologies (an event which is also known as CEATEC) is a trade show held every year in October, in Makuhari Messe, Japan, since the first edition, the one which took place in 2000. The event is said to be the Japanese equivalent of International Consumer Electronics Show, a similar show which takes place in Las Vegas, Nevada, and is not open to general public.

This year’s CEATEC edition has brought several remarkable inventions, more than the last couple of years combined, and the latest product NTT Docomo decided to unveil at the event does no more, no less than to continue the trend. The company is very well known for gripping the Japanese cell phone market and for recently losing the rights to the Apple’s iPhone in favor of SoftBank, which seemed to be the perfect solution, despite the fact that Docomo has a powerful network and enjoys significant brand recognition, locally speaking.



NTT Docomo Inc revealed, therefore, the prototype of a mobile phone that is designed to double as a video projector. The demonstration was made during the CEATEC 2008 event.

The company used for this handset its existing model which was integrated within an ultrasmall projector. Red, green and blue LEDs are used as a light source. In addition, the device features a “DLP Pico” chipset (( DLP stands for digital light processing) designed by Texas Instruments Inc. and it’s actually a DMD (digital micromirror device) with a reduced size for mobile use, its driver LSI and so forth. The projector has 480 x 320 pixels (HVGA) and a luminance of 7.5m, meanwhile the power consumption of the projector module comes to 3W.



The projector is designed to screen a 20-inch image from a distance of approximately 80 centimeters and to offer 100 minutes of operating time (once again, with approximation). It’s more than enough to watch a TV show, podcast, or a short film. As I was saying before, a demonstration took place at the event. The handset projected images and its integrated Li-Ion secondary battery was being charged in the same time. The projector functioned during this test for only 15 to 20 minutes per charge. The reason for something like this to happen is that an existing battery for mobile phones was used.



In order to get this new handset to mass production there must be done some retouches. First of all, it’s necessary to reduce the heat that the projector module, then the power consumption, the cost and, why not, the size of the projector module.

It’s a great concept, there’s no doubt about it, but would it see the light of the day? I don’t know about you, but the company is confident in the success the projector will score, and plans to mount it after three years at earliest, “but only in the highest-end models”.
