When choosing a flat screen TV display for your digital signage project, there are two types of screens to choose from - consumer and commercial or professional display. While both types may produce a result you are looking for with almost similar outstanding quality picture but they are engineered differently. Regardless or screen type, such as LCD, plasma or LED display, you may need to consider that the professional display is 50% higher or doubled the price for a similar screen size.
The professional displays are engineered to work well with a PC with additional features and their architecture supports long hours of operation. On the other hand, the consumer type screens are engineered for home usage and video display are intended for shorter viewing times. Home displays or TV such as those you'd purchase at your local electronics store, work perfectly at home or living room for watching movies and playing video games, but many digital signage applications require a display engineered to handle increased usage, expansion needs and varied locations.
By adhering to the highest quality control standards for components and manufacturing, professional displays offer significantly better Return on Investment (ROI) than consumer-grade displays. Here's why you should consider a professional display instead of a consumer display:
Hours of operationDesigned to withstand long operating hours with thermal characteristics built in the internal design for proper heat dissipation in both portrait and landscape modes. Commercial displays typically incorporates additional fans to dissipate heat. Consumer televsisions are built to operate for about four to six hours a day. Professional displays, however, are designed to run 24/7, so they'll last longer and are less likely to fail at inopportune moments.Tamper resistant control locksBecause flat panel displays are often used in public spaces, such as for digital signage, it's important to secure them to prevent disruptions to communications and tampering with controls such as power, volume and other controls. Professional displays are designed to prevent such unauthorized adjustments in standalone or non-monitored public locations.Vertical or horizontal mounting capabilityConsumer-grade televisions aren't designed to be mounted both vertically and horizontally. When mounted vertically, the television can experience "Gravity Mura," which can cause dark spots to appear on the screen and reduce lamp life. This discoloration in consumer LCD televisions is caused by pressure in the lower part of the screen, which distorts the alignment of the polarizing film. With a professional LCD display, an improved liquid crystal injection method keeps the pressure at the bottom of the screen at a level that is no higher than that on ordinary TVs or those in a horizontal position.
In addition, consumer televisions do not provide airflow for cooling in the vertical position, which can cause the display to overheat and fail earlier than normal. Finally, consumer televisions are usually not designed to be symmetric so they may appear lopsided when mounted in a vertical position.WarrantyConsumer displays usually come with a one-year warranty, which can often be reduced to 90 days or deemed void if the display is used in a commercial application. Professional displays, however, typically come with a standard two-year warranty with an option for an additional three-year extended warranty available."Yogore" stainsThe liquid crystal and PI film for LCD televisions include a variety of impurities. These impurities interrupt the reversion of liquid crystal to its original position. This can cause "Yogore" defects, which can cause boundary lines to appear on the screen, diminishing picture quality. There are drastically fewer impurities in the materials used to manufacture professional LCD displays than TV panels, which severely limits the chances of a "Yogore" stain. This is also called as anti burn-in & image-retention features.
In addition, consumer televisions do not provide airflow for cooling in the vertical position, which can cause the display to overheat and fail earlier than normal. Finally, consumer televisions are usually not designed to be symmetric so they may appear lopsided when mounted in a vertical position.
Touch screen capabilitiesYour average consumer TV is not capable of offering touchscreen functionality. There are professional LCD displays that offer a built-in touch screen, creating a perfect tool for wayfinding in hospitals or amusement parks, for example. In addition, a touchscreen professional display could be used as an interactive information kiosk or at a QSR drive-thru.
