The large modern wall clocks are a fresh alternative to the creative analog wall clocks alternative. They look modern and not make noise and often have large numeric displays that are easy to read. While features vary from one clock to another, some offer additional features such as temperature and date. Digital wall clocks commonly show the numbers on LCD or LED screens. The exact time, minutes and even seconds is displayed as well as a set AM or PM.
Large modern wall clocks display the numbers on one line and not in a circular arrangement and most have rear lights, illuminating the time by making it easier to read at night. The digits are typically a few centimeters tall. While red is a common color for the screen, green and blue are also popular.
Large modern wall clocks run on electricity, either from a wall outlet or batteries. Most digital wall clocks are powered by batteries, but those who offer both options use batteries as a backup in case of power loss. Units without battery backup must be restarted as often date back at 12:00 when the power goes out.
The simplest models show the time as well as temperature and time. More advanced models can set personal messages and reminders. Large modern wall clocks also provide information related to the weather, humidity and temperature.
