Projector
What is a projector and how does it work?
A projector is a device that projects an image from a light source (such as a lamp or LED) onto a large surface such as a curtain or wall. This image can be from any source such as your computer, game console, DVD player or even your smartphone.
Types of projectors:
DLP projectors: use millions of tiny mirrors to create an image. These types of projectors usually have high brightness and vivid colors.
LCD projectors: use liquid crystals to produce images. These projectors usually have high contrast and are very suitable for business presentations.
LED projectors: use light emitting diodes to create an image. These projectors have a longer life, lower energy consumption and smaller size.
Laser projectors: use lasers to produce light. These projectors have very high brightness, accurate colors and longer life.
Projector applications:
Home Cinema: Create a high-quality home theater at home
Presentation: Business, educational and conference presentations
Video Games: Experience video games on a grand scale
Education: interactive education in classrooms
Special events: film screenings, concerts and exhibitions
Which projector is right for me?
Choosing the right projector depends on your needs and budget. Factors to consider include:
Brightness: The brightness of the projector is measured in ANSI lumens. The higher the brightness, the better the image can be seen in brighter environments.
Resolution: The resolution of the projector refers to the number of pixels it can display. A higher resolution means a clearer and more detailed image.
Contrast ratio: Contrast ratio refers to the difference between the lightest and darkest part of the image. Higher contrast means an image with greater depth of field and richer colors.
Input Lag: Input lag refers to the time it takes for the projector to respond to your input. Low input lag is very important for video games.
Connections: Make sure the projector has the connections you need, such as HDMI, VGA, and USB.
