Like most electronic and mechanical devices, alarm clocks come with varying displays and controls. If you already own an alarm clock you might want to think about what’s not working for you. If you haven’t bought an alarm clock in a while or this is your first purchase and you’re not sure what you really need, this guide is the first step in the decision making process.
Most alarm clock users prefer a digital display (i.e. numerals or symbols) vs an analog clock display, where the time is shown by the positions of rotating hands.
Digital alarm clocks usually include Light Emitting Diode (LED) displays that are capable of being lit all the time or just as needed. They typically have a backlight with a dark or light background and black, green or red display characters. Some displays even have an automatic sensor that automatically allows the backlight to come on automatically as the room darkens. There are also adjustable brightness controls for the backlight so you can set the light to your liking. Some offer HI-LOW-OFF controls for all display settings.
For those that need easy to read numerals you may want to choose a very large or jumbo time display on your alarm clock. Very large display alarm clocks have digital numerals from .9″ to 3″ in height. Whether it is for your office, bedroom, classroom, visually impaired individuals, or any other room where a large time display is needed, this is the display feature for you!
Some alarm clock displays include many more options than just time. They may also include display features such as Alarm Time, Day of the week, Month, Moon phases and indoor/outdoor temperature with a Fahrenheit/Celsius option. Some even offer a Projection feature that displays information on the ceiling or wall. Others include controls to set a 12 or 24 hour time format.
