![]() The function of a projection alarm clock requires a backlight, either an incandescent bulb or LED. Projection alarm clocks use both liquid crystal display (LCD) and light emitting diode (LED) technology. The projector operates along the same principles as a movie projector. As you set up your new clock, you can choose a 12-hour or 24-hour (military time) readout. Most projection alarm clocks show a digital display of the time. Every projection alarm clock includes a built-in projector that can be rotated up to 180 degrees to project the image onto the most viewable spot on your wall or ceiling. The genius behind the projection alarm clock is that you can read the time on the clock face, or you can simply look up at your wall or ceiling to see the time projected in a clearly visible image. Read on to learn about the features to consider as you shop for the best projection alarm clock. Select from LED or LCD displays in optional colors, and don’t forget to choose an alarm ringtone that you’ll want to hear as you awaken. Additionally, you can choose the color and design of the time display on your clock face as well as the angle of projection for the enlarged image. Consider whether you want to plug your projection alarm clock into an AC outlet, use a rechargeable battery, or insert alkaline batteries.
