DOOH LCD Enclosure USA explain.

LCD screens now play an important roll in our every day lives, whether we notice them or not.  We pass them by on a daily basis on our way to work – on the road side, whilst shopping – at the point of sale, or even in the doctor’s office – a touch screen and interactive monitor for the checking in procedure.

Many advertising companies are choosing to locate these digital posters externally of a building, where passing trade will notice the dynamic images promoting products and merchandise.  No opportunity is missed, as each and every person is a potential customer.  However, these screens, whilst a valuable sales asset, can be a substantial outlay, so any possible prospect for damage must be eliminated.

A secure outer case, made from a metal, be it either mild steel then powder coated or for extremes, like coastal positions, a stainless steel LCD enclosure.  These are fitted with anti theft and anti tamper bolts, so once fixed in place are virtually impossible to destruct, however they are removable with this correct tools should the LCD enclosure need repositioning.  Guarding is a must, as some of the industrial large screen TV’s are very expensive, so replacing them is out of the question.  Many insurance companies are refusing to insure against damage or theft if the screen is not protected.

Not only is sheltering digital flat screens from the weather important, but also considering the temperature is another.  Varying degrees, from the desert heats of Arizona to the freezing sub zero of Alaska, and those states in between which have both, need addressing.  A thermostatically controlled heater or cooler – or a combined unit will deal with most situations.  The electronic parts within the plasma or LCD screens may freeze due to air moisture turning to ice crystals, so ensuring the temperature is controlled by a thermostat, which starts accurately, is essential.  Similarly, one which controls the heat either created by weather temperatures or by the electronic parts inside the digital display or monitor will avoid overheating whilst being shielded from external forces of harm.

Who uses an LCD enclosure?

It is possible to enclose a digital screen or VDU, for example in a fish factory or dairy, where it is situated in a total wash down area.  Obviously computers, electrics and water do not mix!, but by enclosing the hardware, water jets can be used effectively without harming the computers or screens.  There are many applications where steel enclosures are suitable protection and at a fraction of the combined initial outlay for the hardware and software and potential down time affecting the data capture of production line statistics, is a considerable and worthwhile investment.

For other extreme conditions, an LCD enclosure made from stainless grade steel is a worthy option.  It will guard against; chemicals, sand, rust and the salt of the sea, to name but a few, as the material will not degrade and offer optimum protection.  Whilst this option is not painted, the alternative mild steel unit can be powder coated to give both a protective finish and compatible company image, as some customers request corporate colors.
