Why invest in an LCD or laptop privacy screen? Combine the popular usage of laptops for business, schooling, and private use with the increasing access to open area, wireless internet networking, and the vulnerability of confidential information becomes obvious. There are other protective benefits as well:

  • ID theft has cost numerous individuals financial, emotional and myriad legal problems, so prohibiting people access to addresses, names, phone numbers, account numbers and other personal specifics makes sense.

  • Failure to protect corporate data has cost companies billions of dollars a year, such as when contracts are lost as a result of data viewed prior to negotiations, and other such occurrences.

  • Personal information disclosure laws, such as HIPAA, are restrictive and require steps be taken to protect certain personal information.

  • The increasing use of LCD testing stations in high schools and colleges has increased opportunity for cheating glances at nearby computer screens.

  • Glare reduction properties incorporated into most privacy filters makes for easier reading and can reduce eye fatigue or headaches brought on by screen glare.

  • The monitor screens for desktop LCDs and laptop computers are delicate and can be easily scratched, but attaching privacy computer filters offers a layer of protection from accidental contact. 

The notebook privacy screen solution. Do you want a person sitting near you to know your business? If you're working in public areas and the information is of a confidential personal or business nature, keeping that information out of the hands of strangers or those not on a "need to know basis" makes good sense. A quality monitor privacy filter is a low cost solution to common problems that could cause serious consequences.

A laptop privacy screen helps prevent "snooping." A survey by Harris that was commissioned in February 2006 received responses from 601 business travelers (+/-4% margin of error). 45% of participants admitted to sneaking glances at the laptop screens of others who were near them in public areas. The information was of interest to 42% of those sneaking a peek.

On the flip side of the equation, of the total travelers responding, over half (51%) said that they'd noticed people reading their screens while in public areas such as coffee shops or waiting lounges. Queried about what they were working on at the time, 1/5 said it was confidential business matters while another 16% were working on confidential personal information. Yet, despite this, almost half of the people responding admitted that they rarely or never do anything to stop the intruders. Questioned further, 84% of all those surveyed said their laptop was used primarily for business-related matters but "only 4% worked for companies that regulated business-related work in public places."

Author Chris McGinnis (The Official Business Traveler's Pocket Guide: 165 Travel Tips Even the Best Business Travelers May Not Know) is quoted in the article saying that "...it's always important to protect the data on your screen" because "...people do fixate on laptop screens and you never know what they will do with the information they discover."

Three other options to prevent your computer's screen information from being viewed. Without a reliable privacy filter, laptop computer users must practice manual methods to prevent their screen's information from being read: Turn off your computer; or change your seat or seat positioning; or shield your screen by arranging other objects (briefcases, plants, etc) to block its view. While all these can be effective, they're also extremely inconvenient for the computer user; having to turn off your computer can obviously have a negative impact on your working effectiveness.

A privacy filter helps keep people honest, too. While the majority of school tests are still being done with pen and paper, there are many more schools implementing screen-based testing. Yet, due to their close seating proximity, unprotected computer screens (which stand vertically, compared to the horizontal plane of writing paper) are relatively easy to read and test results can be skewed due to cheating.

In the early 2000s, a principle at Farnborough Sixth Form College in England was the first to promote privacy screen usage for school exams by contacting a manufacturer for sample products that could be used in supervised testing. The school had already tried placing solid partitions between students, which, while it did prevent straying eyes, also (a) made it difficult for instructors to spot students reading "crib sheet," plus (b) administrators found the partitions unattractive. The success of that school's high profile experiment has led to increased implementation at other schools and testing sites.

Glare Reduction Radius

A quality LCD screen filter provides monitor visibility for the user who is sitting directly in front of the screen as well as reducing glare. Attempts to read the monitor's information by individuals sitting beyond the set viewing parameter are stymied. Some styles blur images, while those constructed using Micro Louver Technology actually black out the screen at certain angles.

Computer Filters / Anti Glare Filters

Make certain your laptop privacy screen also protects against common glare. Glare is a common cause of computer user eyestrain with an A.O.A. (American Optometric Association) survey noting that as many as 75% of Video Display Terminal Users (VDT) report VDT-related eyestrain. Not only that, but the awkward positioning workers may sit in as a result of screen glare can be the cause of  back, neck or shoulder pain they're experiencing. Glare can result from a combination of factors having to do with the source of light and the positioning of the computer screen in relation to the light source. When investing in privacy screens for either your desktop LCD or notebook computers be certain they're purposely designed to reduce common glare. While no system will be able to ensure you can read your screen well while sitting in the daylight, common work situations should be well managed.

LCD filters are available with frames and in a flexible, frameless style. There are very effective models whose manufacturing process utilizes Micro Louver Technology. This "louver-like" process "blacks out" screen views from angles beyond a set parameter, while providing front seated users a full view. Glare is also handled by these tinted screens. There are also other styles of filters available that incorporate simple coatings to blur screen images viewed from angles.
