Outdoor digital signage, information screens and outdoor TVs all use LCD displays. Little difference exists between a standard LCD screen used at home and an outdoor LCD display, except outdoor screens require protection from the weather and other outdoor elements to enable functionality in outdoor locations.
Many manufacturers now produce outdoor displays, thanks to the burgeoning outdoor digital signage market, but these outdoor TVs cost many times more than the price of standard indoor displays. This price often prohibits many businesses from using outdoor digital signage, providing outdoor information or entertaining customers with an outdoor TV.
Outdoor LCD Display Enclosure
Another method of utilizing an outdoor LCD display is to use standard device but protect it in LCD enclosure. Made to TV manufacturer's standards, such as VESA (Video and Electronic Manufacturers Association), LCD enclosures come in a variety of sizes, enabling the housing of almost any make and model screen.
Normally, the protection offered by a LCD enclosure is fairly comprehensive, keeping the housed LCD screen dry from the rain, free of airborne particles, at a steady temperature and provides rugged defense from vandals and attempts at theft. Protecting from all of these factors is essential for any outdoor LCD display.
Weatherproofing
Perhaps the most obvious from of protection for an outdoor LCD screen is protection from the weather. Water and electronics obviously do not mix, so keeping the display dry is vital. Rainfall needs keeping out of the display, but this is not as simple as it sounds. All TV screens require access to air to prevent overheating.
A LCD screen has a ventilation system on it that enables air to penetrate and carry any excess heat away; however, this also provides access for any water or rainfall. To combat this problem, LCD display enclosures have shaped channels that permit airflow but not water ingression, enabling heat transfer but preventing moisture intrusion.
Temperature Control
Outdoor LCD display enclosures provide a controllable environment for the screen with the temperature kept at a constant thanks to climatic systems. Cooling fans transfer away heat generated by the screen; while in cold ambient temperature, heater systems maintain a minimum temperature inside the enclosure.
Insulation, additional fans and even air conditioning provide additional temperature control when needed, maintaining a steady internal temperature for the screen.
Other Protection
The weather and temperature are not the only elements that can damage an LCD display. Dust, when allowed to penetrate inside vents can cause overheating and even short circuits. Attracted to static, dust can also cover screens and make them unreadable. Prevalent in industrial locations and even outdoors as wind-blown dust and debris, outdoor LCD screen enclosures are ideal for protecting screens in this sort of area.
Another form of protection offered by a LCD screen enclosure is ruggedness and defense against vandalism. Usually manufactured from steel, with shatterproof screen, outdoor LCD screen enclosures provide physical protection from physical shocks and impact.
Used for outdoor digital signage, indoor display in harsh environments and for watching TV outdoors, outdoor LCD display enclosures are a comprehensive form of protection that allows the use of standard LCD displays in almost any environment.

A cheap tablet PC is one of the most popular gadgets in the technologically advanced world of today. One of the main reasons for this is the broad spectrum of users it is great for. From students and lecturers to medical professionals and business people, the tablet pC in its different types and forms is used widely. Tablet PCs have gained massive popularity since their inception and to satisfy specific needs and preferences these are available in a range of types.
Broadly speaking, a cheap tablet PC comes in two types; slate and convertible. The slate type is a classical representation of the purpose of the tablet PC. It is basically a high technology flat computer screen which can be placed on the desk. Manipulation on the screen is done by using an electronic pen called a stylus instead of the conventional keyboard and mouse. The slate can practically be used as a piece of paper (a very high tech one) on which you can scribble your notes and more on. Furthermore, a keyboard and other accessories can be purchased separately and attached to it.
The second type of tablet is the convertible which essentially works and looks like a laptop. It is has a screen that can be flipped open and manipulation is done via the keyboard and touch pad which come attached to it in addition to a CD Rom and more. The screen can be swiveled around one hundred and eighty degrees and put down over the keyboard to use it like the slate type and operate it with the stylus.
Tablet PCs are also classified on the basis of their technological features such as screen size, connectivity, pressure sensitivity, size and of course, brands. The choice of which model is the best for you depends on your personal preference and your specific needs and demands. The screen size is directly analogous to the drawing and writing space the tablet will offer you. You may find different types of tablets with sizes such as eight inches by six inches, nine inches by twelve inches and larger.
Another important way to classify the types of tablet PCs in the market is their pressure sensitivity. Higher the sensitivity, more accurately will your writing and drawing be registered and saved. There are numerous different pressure sensitivity levels in these handy tools, the highest and best being 1024 pressure levels.
The various types of tablet PCs also further illustrates the purpose of its creation; to cater for the technological working needs of a broader spectrum of people.
The advancements in printing have been numerous throughout many years. The laser printer was invented in 1969 at Xerox by a researcher named Gary Starkweather. He had an improved and functional printer working and printing around 1972. The idea came about by modifying an existing xerographic copier. Starkweather disabled the imaging system, created a spinning drum with 8 mirrored sides and focused a laser on the drum. Light from the laser bounced off the spinning drum, sweeping across the page as it traveled through the copier. The hardware was completed rather quickly but the software and control interface took much longer. The first laser printer was the IBM 3800 in 1976, typically used for high volume printing like invoices and mailing labels. It was a very large device but can be accurately named the beginning of laser printers.
The cartridges in most of these printers are usually quite easy to replace. The laser printer cartridge is meant to make things much easier and allow for quick replacement and overall efficiency for the printers they come in. The only issue is, they are usually quite pricey and you are stuck buying the same brand that printer was made by. The laser printer cartridge is not interchangeable, in most cases if you have an HP printer, you'll need an HP printer cartridge.
The difference between ink cartridges and the laser cartridge is in the material used. InkJet printers use liquid while the toner cartridge used in a laser printer is powder. Manufacturers use various polymers and formulas to produce a slab of toner, then pelletize or break it and turn it into a fine powder. The advantage in using toner ink cartridges is the much more extensive use you get out of laser printers and toner itself over liquid ink.
The most popular brands of laser printers are in my opinion, HP, Brother, Lexmark, Dell and Canon.
