While traditional graphic LCD modules with grey letters and numbers against a white or yellowish background are still the most common types of LCD displays available, custom manufacturers can create graphic LCD modules in practically any color scheme. LCD display modules can presently be manufactured in practically any size necessary for applications that range from small medical or electronics tester display windows to huge outdoor advertising presentations.
Simple graphic LCD modules, such as the ones commonly seen in calendars, fever thermometers, watches and calculators, are readily available from suppliers who manufacture them in bulk and keep stocks on hand for immediate shipment. Custom manufacturers can design, manufacture and ship
graphic LCD modules of practically any size or color scheme within a reasonable amount of time after a customer places an order.
Regardless of the size, brightness and color scheme of any particular module, graphic LCD modules retain the energy-saving characteristics of small consumer LCD modules. Most LCD displays can run on DC power, or even o a combination of DC and solar battery power. This makes even the largest LCD displays ideal for color displays in locations where power supplies may not be readily accessible or practical. A rural billboard, a graphics display at an outdoor concert and a complex monitoring display for a remote solar power installation are all examples of applications that take advantage of the low power consumption of LCD graphics displays.
Graphic LCD modules have come a long way from the grey letters and numbers that initiated the LCD era. Today, custom manufactured LCD displays are available for everything from simulated fireworks shows and advertising billboards to readouts for the most intricate monitoring and measuring devices.
