Pocket LED Projectors

The main gist behind bringing forth LED into projection technology is because they - - - -
- have a longer running time (energy efficiency-wise)
- easier than conventional lamp technology to start up - powering on and off is of much more rapid rates
- much lighter - disperses the same amount of light (and even more) of a conventional lamp with less electrical components - hence more compact
- generates less heat

In relation to LED projectors, many companies like Epson have already successfully developed such products that are feasible to the public yet at a sustained cost.
Again, due to the functionalities of the entire product - LED light source with LCD screen and magnification lens.

Like any projector on the market nowadays, the use of LCD screen provides clarity due to the intense closeness of pixel counts, and as light passes through, the pixels can reiterate the notion of positive and negative space - either blackening our the light, or letting it pass through to form an image. After so, the projector's lens acts as a magnifier, expanding the image onto a viewing surface (usually the wall) and magnifying all the tiny details that would have been present in the original format image.

Epson's current 'pocket LED projector" sits at 13.8 by 10cm small.

However, there is another one called "Pro-920 Pocket LED Projector" which sits at 9 by 8.8 by 4cm.

But wait! There's a CHINA PROJECTOR which sits at 2 by 3 by 0.9cm Small!
LED light sourced - LCD screened and projection distances of 1m to 6m!
