A standard for measuring light, is the number that are usually offered by the manufacturers for not providing any additional information to compare one product with another. Lux is the International System unit of illumination, equal to one lumen per square meter. Also called candle-meter, meter-candle. Primarily used for projectors with lower lumen
This refers to the "half-life" of the lamp inside the projector. This is the point where the lamp is half as bright as it was when it was first being used. It will gradually lose brightness with use, and it is recommended to replace your lamp when it exceeds it's lamp life. In fact the lamp life rating is the time till the bulb is producing
It measures the amount of light produced by a front projector. This is expressed in "lumens" or "ANSI lumens." A larger number, the greater light output. Light output varies depending on mode (color and white light output). Advanced, high-speed auto iris function adjusts light output up to 120 times per second. The ANSI contrast
One method that allows us to see the full picture of how it looks in a theater. As a result, the image width is greater than the height of it. In a TV screen with a standard format (4:3), the videos appear in letterbox format with black horizontal bar at the top and bottom of the image.
Many projectors, whether in a 16:9 or 4:3 native aspect ratio, are able
This new feature available in some projectors makes moving the position of the projection in a few degrees vertical or horizontal, through a movement in the lens and not through digital keystone correction as in, thus avoiding the loss of sharpness. Vertical len shifting is the most popular type of shift because it allows for keystone correction and assist
It means "Liquid Crystal On Silicon" Liquid Crystal on Silicon. This new technology combines the qualities of LCD and DLP technology.
The technology is based on the management of 3 as LCD panels, but using the concept of Reflection of light that uses DLP.
LCOS (Liquid Crystal on Silicon):
A projection technology TV screen has to be a liquid
It means "Liquid Crystal Display", liquid crystal display. This technology is mainly used in screens for laptops. As for many projectors use 3 panels with a prism to generate the image. This technology in projectors is rich in color and a lamp requires less power than in the DLP technology.
The technology in liquid crystal displays is one of the
Portion of a television transmission that controls brightness of the red, green, and blue proportions in a television picture. The standard luminance setting in a picture is 30 percent red, 60 percent green, and 10 percent blue. These numbers are adjusted to produce varying colors, grays, whites, and blacks.
Element or glossy black and white of an image. Is
Unit that expresses the amount of light perceived (luminous flux). The brightness of the projector is measured by dividing the projected image into nine sections and finding the average number of lumens in the center of each.
Unfortunately the methods for calculating this measure are not the same by different manufacturers, so it is sometimes misleading to
