The Rise Of Sunlight Readable LCD Displays

By Alex Stein


There has been rising interest from a number of players in the application of digital screens in outdoor displays. There is agreement from all circles of the industry that the invention of sunlight readable LCD screens has not only spurred this demand but led to even more effective applications. Those dabbling in industrial displays as well as advertising have lauded the rise of this innovative medium.

The outdoor advertising world has literally been turned upside down with the rise of this powerful medium. The efficacy of this method in grabbing the attention of a market where the seller wants to target has been lauded all over the world. It is especially noteworthy that the need to wait for daylight to recede and dusk to appear before such displays could be turned on has completely been dispensed with.

The phenomenal growth can also be attributed to a number of public usage applications for the screens. Everything from road signs, warnings, time display units to traffic information have been easily and more effectively implemented on this platform. Organizations responsible for providing such type of information are embracing the idea, spurred on by the impressive results.

Another factor that has greatly contributed to many organizations shifting to this mode of displaying information is that they are increasingly energy efficient. Compared even to the more innovative devices from awhile back, the new media has proven unbeatable. This is a welcome relief for organizations seeking to put a lid on spiraling energy bills.

A major factor in the power consumption debate has for long been how to enable traditional LCD displays to work with adequate efficacy. With such displays, it has been necessary to increase the brightness and contrast ratios vastly in order to ensure that they can be read well even in bright sunlight. This usually means the displays consume even more power making the cost of running them disproportionate to the benefits.

Some traditional LCD displays are still very much in evidence in major cities of the world even with the rise of the newer technology. To increase their efficacy in daylight hours, backlights were implemented in the design to offer added illumination. While this is partially effective as a solution, the devices end up being too ungainly for use in some specific application areas where space is at a premium.

The use of anti-glare screens was another strategy that was implemented in trying to ensure the readability of the signs even in broad daylight. This was not a satisfactory solution in a number of senses especially because this form of glass can prove to be particularly brittle for some applications. The readability levels were also not particularly impressive.

The recent growth in the use of sunlight readable LCD display screens is not without justification. They offer an effective alternative for companies and public welfare organizations that need to present a message to the general public in a visually interesting manner. They have obvious advantages over more traditional media especially in terms of appeal as well as energy efficiency.
