Andowl Q200 Mini LED Lamp Projector with Built-in Speakers BlackCode: 34273379

Andowl projector Q200 with a resolution of 800 x 480 pixels and an image diagonal in the range of 40 - 120". This size depends on the distance at which the projector is placed from the projection surface. In this case, the projection distance is in the range of 1.4 - 4.2m.The projection technology is how the light of the projector lamp is transformed into an image to be projected through a lens.It is of LCD technology and its lamp is of the LED type, which has a duration longer life but lower brightness than ordinary bulbs with good color performance.This technology is named after the initials of the words Liquid Crystal Display.The image is created by a panel of liquid crystals that produces combinations of the three colors of base: red, green, blue. This results in very good color performance, even in black. Brightness and contrast, or contrast ratio, are two very important characteristics that are taken into account, along with the projection distance and the maximum diagonal you want to get, for choosing a projector. It has a brightness of 100 lumens and a contrast ratio of 1000:1. Contrast indicates the difference between the darkest and lightest parts of an image and is an indicator of image quality. The image projected by a projector with a low contrast ratio looks washed out and flat. Conversely, with a high contrast ratio, it appears more realistic and with greater "depth". Brightness indicates how much light the projector can cast on a given surface. The rule of thumb suggests that "brighter" projectors should be preferred in spaces with lots of light or multiple light sources, while "darker" ones should be preferred in dark spaces.
