Hewlett Packard "today announced that it has developed a technology that enables twice the resolution of digital projection displays without increasing the cost of the projector. HP has filed patent applications related to this resolution enhancement technology, code-named "wobulation," and in case you seek an explanation of how it works, here's HP's take:
| ....In typical digital projection displays, increasing image resolution requires increasing the number of pixels in the spatial light modulator (SLM). This significantly increases the complexity and cost of the SLM and therefore the final product. Because the SLM is usually the most expensive component in a digital projection display, HP's "wobulation" technology is an economical method of increasing the resolution of digital projection displays without changing the SLM. "Wobulation" technology works by generating multiple sub-frames of data while an optical image shifting mechanism then displaces the projected image of each sub-frame by a non-integral number of pixels. The sub-frames are then projected in rapid succession to appear as if they are being projected simultaneously and superimposed. The resulting image has significantly higher resolution than images produced by conventional digital projection devices. The resolution enhancement technology is applicable to both front projection and rear projection applications. HP's "wobulation" technology is not dependent on a particular SLM technology and is expected to work with future SLM technologies. HP plans to introduce front projection and rear projection products in 2005 based on the "wobulation" technology.... |
Kudos to you if you understood that. So next time you invite friends over to watch the game on your brand new HP Projection TV, be sure to let them know that the program will be "wobulated".
