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.
DurabilityConsumer televisions aren't built for operating in demanding environments. With professional displays, there are a variety of options to fit any environment. For instance, professional displays often have a fanless design, which is ideal for environments with high air pollutants, such as Quick-Serve Restaurants (QSRs), which can lead to failure in a display by exposing internal components to elements such as moisture and smoke. In addition, there are professional LCD displays that are IP66-compliant for dustproof and water resistant protection. These are ideal for outdoor use at bus terminals, factories and ski resorts, for example, and are built to function in both cold and hot weather. However, for small project of non-critical application such as pelamin kahwin, regular TV is much cheaper and affordable.
Expandability and integration optionsUnlike consumer televisions, many professional LCD displays offer Slot2.0 architecture. Slot2.0 accommodates optional boards, expanding the display's application possibilities. The technology allows you to easily mount applications and allows for a variety of input terminal cards, including the i5/i7 plug-in PC capable of running even the most powerful software applications. Professional displays also often offer a flexible design for removing and re-installing media PCs without removing the display, simplifying field support, while cutting down on operational expense. Most models recognize all PC resolutions including wide formats and different refresh rates (1024X768@ 60, 72, 75, and 85HX) in addition to TV/video resolutions.
Viewing angleProfessional displays are built with an In-Plane Switching (IPS) panel, which prevents color change when images are viewed from a wide angle. Some consumer televisions are built with a Vertical Alignment (VA) panel. While both panels have viewing angles of about 178 degrees, the image on the VA panel will be of poorer quality, displaying incorrect colors when viewed from off-center angles.
Device controlProfessional displays offer increased device control via RS232 or a LAN control. Let's say a store has a dozen screens. These control options allow all the devices to be controlled from a central location, eliminating the need for a person to run around with a remote control to turn screens on and off or adjust other settings. For larger networks, RS232/LAN Control can be used to monitor hundreds, even thousands, of displays from a central location. Consumer devices lack this capability.
Built-in rear speakersThese eliminate side protrusions for a clean, modern design with seamless appearance for multi-display video walls. This will be especially important if the content you're displaying has an audio component.
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.
