Ricoh projector WUL5A40ST with pixel resolution. The projection technology is the way in which the light from the projector's lamp is converted into an image to be projected through the lens onto a surface. This particular one uses 3LCD technology and its lamp is of the laser type, which has a longer lifespan than LED lamps as well as very high brightness and excellent color and black performance.

This technology takes its name from the initials of the words Liquid Crystal Display, developed by the company Epson, and is an evolution of LCD technology. The image is created by three liquid crystal panels each of which produces one of the primary colors: red, green, blue. The 3 colors are combined through prisms and projected simultaneously from the lens as a complete image, with much better color performance even in black.

Brightness is a very important feature to consider, in conjunction with the projection distance and the maximum diagonal you want to achieve, when choosing a projector. This particular one has a brightness of 4500 ANSI Lumens which indicates how much light the projector can deliver on a specific surface size. The general rule suggests that brighter projectors should be preferred in spaces with a lot of light or multiple light sources, while darker ones should be preferred in dark spaces.
