Daily Use projector AOPEN Fire Legend QH31s by the company Aopen, with resolution 1280 x 720 pixels.
The projection technology is the way the projector's lamp light is converted into an image to be projected through the lens onto a surface. This one is DLP (DMD) technology and its lamp is LED type, which has a longer lifespan but lower brightness than regular lamps, with good color performance.
This technology is named after the initials of the words Digital Light Processing, it is the most widespread projection technology, and there are projectors with one or three DLP chips. The image is created when the projector lamp light passes through a rotating color wheel and is reflected by a chip with hundreds of thousands of tiny mirrors, each corresponding to a pixel. This chip is called DMD (Digital Micromirror Device). They are suitable for spaces with plenty of lighting, such as classrooms or conference rooms, and have good color performance.
Brightness and contrast, or contrast ratio, are two very important features that are taken into account, in combination with the projection distance and the maximum diagonal you want to achieve, for the selection of a projector. This one has a brightness of 150 Lumens and a contrast of 1000:1.
Contrast indicates the difference between the darkest and the brightest part of an image and is an indicator of image quality. The image projected by a projector with a low contrast ratio looks faded and flat. In contrast, with a high contrast ratio, it looks more realistic and with greater "depth".
Brightness indicates how much light the projector can deliver on a specific surface size. The general rule suggests that "brighter" projectors are preferred in rooms with plenty of light or several light sources, while "darker" ones are preferred in dark rooms.
