lcd screen saver quotation

Remember the old days when you spent hours hunting for the coolest screensavers? You probably haven"t done that for some time, and you aren"t really missing out on anything if you haven"t.

In fact, in the world of modern screens, screensavers are wholly unnecessary. Screensavers once served an important purpose, but they"re now obsolete. Feel free to never use a screensaver ever again—but that being said, there are a few reasons why you might want to.

When a CRT monitor shows the same image for too long, however, the color permanently settles on the screen, causing what is known as screen burn-in or image burn.

So, for example, a static element on the screen—like the Windows taskbar or the Mac Menu bar—would, over time, get burned into the screen. Even when you switched the screen off, you could see an outline of the taskbar"s ghost.

Screensavers were meant to stop this. When your computer wasn"t being used, the screensaver would jump into action and play a video that disrupted these static pixels in order to prevent image burn.

While the logic of screensavers is solid, it"s only relevant today if you still use CRT monitors or plasma screens. LCD and LED monitors don"t have image burn problems like they do, and since laptops and monitors are now primarily LCD or LED, the purpose of the screensaver is moot.

Note that even on LCD and LED monitors, displaying the same image for many days or weeks can cause "stuck pixels", but that"s a temporary issue. You can actually fix stuck pixels with software, whereas CRT image burn is a permanent problem.

Some people believe that screensavers exist to save power, but that"s entirely false. Computers actually use more power when running a screensaver in order to keep the screen on. Want to save power? Ditch screensavers completely. All modern operating systems have power-saving features that turn the screen off when inactive.

While screensavers are no longer necessary to "save your screen", they can still be useful for other things. For example, when you go idle, your monitor can turn into a heads-up display for information, motivation, tools, or entertainment.

Additionally, computers are often connected to TVs these days, making it cheaper and easier to build powerful gaming computers. The downside is that there"s a good chance you still have a plasma TV, which requires a screensaver because it is susceptible to burn-in like CRTs.

You can play old NES games for free in your browser already, but there"s something exceptionally cool about the UberNES Screensaver. It demos NES games as screensavers and lets you play them with the tap of a button.

Uber NES Screensaver is easy to set up if you follow the instructions carefully, and you can download several popular NES games through a selectable menu.

What does our little blue rock look like from way up in the International Space Station? There"s a way to set up this live stream as your screensaver.

This works only on Windows because you need to download the free HTML Screensaver program from Screensaver Planet. Once installed, just go to Settings > Personalization > Lock Screen > Screensaver. In the next panel that pops up, click the Settingsbutton and paste in the URL for the ISS"s live feed on Ustream.

After finalizing everything, you can admire Earth every time the screensaver comes on. If you get bored, you can follow the same steps with any other URL you want.

In Windows, Mac, and Linux, you can set your screensaver to display a custom message. You can use this message to set up a reminder to take your pills, finish an important task of the day, or generate a word cloud of motivation.

You could find a suitable live feed and try the URL with HTML Screensaver. Alternatively, just download any collection like Apple TV Aerial Views and set it as your screensaver. A quick way to do this:

Screensavers are a thing of the past, but that doesn"t mean they don"t have their appeal and uses. While you can forgo them completely, there are many ways to make them invaluable again. Instead of protecting your monitor, for example, they can display reminders, inspirational quotes, or stunning landscapes.

Exploring screensaver tools also introduces you to your computer"s basic functions. You can take this further and have fun as you get to know your system"s ins and outs, from minute apps to smart commands.

I quickly found myself search­ing for more quotes about design, there are tons of really good ones out there. After a while I star­ted think­ing, would­n’t it be great if we could dis­play these quotes on our com­puters in full­screen mode? maybe as a screensaver or an inter­act­ive slideshow?

I’m all about sur­round­ing myself with things that inspire me, things that help set a mood and get you think­ing. Over at the nclud stu­dio we have a set of LCD screens where we dis­play cli­ent work dur­ing meet­ings or some­times use to play Mario Kart. When not in use the screensavers come on and I figured, let me setup a sys­tem that allows us to dis­play these inspir­ing quotes in full screen mode, as a screensaver. What bet­ter to get you in the mood when design­ing than read­ing design quotes from some of the great minds of past times and our time?

Mac users can use IdleWeb, a nice little app that allows you to set up any webpage as your screensaver. Just make sure you set it up in “kiosk” mode with­in the screensaver options.

Anoth­er option is to use browser plu­gins to set the browser win­dow in full­screen mode, again I haven’t tried yet, but I’m sure it’ll work just fine.

Plasma displays are highly susceptible to burn-in, while LCD-type displays are generally less so. Because of the more rapid luminance degradation of current organic compounds used in OLED-type displays, OLED is even more susceptible to burn-in than plasma.[citation needed] In addition, the wide variation in luminance degradation with OLED [1] will cause noticeable color drift over time (where one of the red-green-blue colors becomes more prominent).

In the case of LCDs, the mechanics of burn-in are different than plasma and OLED, which develop burn-in from luminance degradation of the light-emitting pixels. For LCDs, burn-in develops in some cases because pixels permanently lose their ability to return to their relaxed state after a continued static usage profile. In more typical usage profiles this image persistence in LCD is only transient.

A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name)OLED technology, which has individual pixels vulnerable to burnout), screensaver programs are still used for other purposes. Screensavers are often set up to offer a basic layer of security by requiring a password to re-access the device.volunteer computing projects.

Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods, the properties of the exposed areas of the phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen, called a screen burn-in. Cathode ray televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.

For CRTs used in public, such as ATMs and railway ticketing machines, the risk of burn-in is especially high because a stand-by display is shown whenever the machine is not in use. Older machines designed without burn-in problems taken into consideration often display evidence of screen damage, with images or text such as "Please insert your card" (in the case of ATMs) visible even when the display changes while the machine is in use. Blanking the screen is out of the question as the machine would appear to be out of service. In these applications, burn-in can be prevented by shifting the position of the display contents every few seconds, or by having a number of different images that are changed regularly.

Later CRTs were much less susceptible to burn-in than older models due to improvements in phosphor coatings, and because modern computer images are generally lower contrast than the stark green- or white-on-black text and graphics of earlier machines. LCD computer monitors, including the display panels used in laptop computers, are not susceptible to burn-in because the image is not directly produced by phosphors (although they can suffer from a less extreme and usually non-permanent form of image persistence).

While modern screens are not susceptible to the issues discussed above, screensavers are still used. Primarily these are for decorative/entertainment purposes, or for password protection. They usually feature moving images or patterns and sometimes sound effects.

As screensavers are generally expected to activate when users are away from their machines, many screensavers can be configured to ask users for a password before permitting the user to resume work. This is a basic security measure against another person accessing the machine while the user is absent.

Some screensavers activate a useful background task, such as a virus scan or a volunteer computing application (such as the SETI@home project).Ken Burns panning and zooming effect is sometimes used to bring the image to life.

The first screensaver was allegedly written for the original IBM PC by John Socha, best known for creating the Norton Commander; he also coined the term screen saver. The screensaver, named scrnsave, was published in the December 1983 issue of the Softalk magazine. It simply blanked the screen after three minutes of inactivity (an interval which could be changed by recompiling the program).

The Atari 400 and 800"s screens would also go through random screensaver-like color changes if they were left inactive for about 8 minutes. Normal users had no control over this, though programs did. These computers, released in 1979, are technically earlier "screen savers." Prior to these computers, games for the 1977 Atari VCS/2600 gaming console such as Combat and Breakout, included color cycling in order to prevent burn-in of game images into 1970s-era televisions. In addition, the first model of the TI-30 calculator from 1976 featured a screensaver, which consisted of a decimal point running across the display after 30 seconds of inactivity. This was chiefly used to save battery power, as the TI-30 LED display was more power intensive than later LCD models. These are examples of screensavers in ROM or the firmware of a computer.

In 2015 the screensaver "Event listeners"work of art that was purchased by a museum (Museum of Applied Arts, Vienna) using the cryptocurrency bitcoin.

Modern graphics technologies such as 3D computer graphics have allowed a wide variety of screensavers to be made. Screensavers with realistic 3D environments can be programmed and run on modern computers.

Screensavers are usually designed and coded using a variety of programming languages as well as graphics interfaces. Typically the authors of screensavers use the C or C++ programming languages, along with Graphics Device Interface (GDI), such as OpenGL ("Open Graphics Library", which works on many, if not most, platforms capable of 3D rendering), or alternatives such as Microsoft DirectX (which is limited to Microsoft platforms, mainly Microsoft Windows and the Microsoft Xbox), to craft their final products. Several OS X screensavers are created and designed using Quartz Composer. The screensaver interfaces indirectly with the operating system to cause the physical display screen to be overlaid with one or more graphic "scenes". The screensaver typically terminates after receiving a message from the operating system that a key has been pressed or the mouse has been moved.

If the system detects inactivity lasting longer than the time specified in the control panel, check if the active program is a simple program (and not another screensaver) by sending the "WM_SYSCOMMAND" message with the "SC_SCREENSAVE" argument. If the program calls in response the standard system function (DefWindowProc), the screensaver defined in the control panel screen runs.

A Windows screensaver is a regular Portable Executable (PE) with the .scr file extension. This enables malware authors to add ".scr" to the name of any win32 executable file, and thereby increase likelihood that users of Microsoft Windows will run it unintentionally. In addition, this program should support the following command line parameters:

Previews the screensaver as child of window. (presented as unsigned decimal number) is an identifier (handle) of the window in which the preview should appear.

Internally, the screensaver must define a class that is subclass of ScreenSaverView. The new class must be assigned as NSPrincipalClass in the xcode project, so that when the screensaver is launched by the system, this class gets instantiated.

As one of the first screensavers appeared in 8-bit Atari computers, forcing systemic color changes when the computer is idle lasting a few minutes (different times depending on the model), stored in the system ROM of the computer.

Monitors running screensavers consume the same amount of power as when running normally, which can be anywhere from a few watts for small LCD monitors to several hundred for large plasma displays. Most modern computers can be set to switch the monitor into a lower power mode, blanking the screen altogether. A power-saving mode for monitors is usually part of the power management options supported in most modern operating systems, though it must also be supported by the computer hardware and monitor itself.

Using a screensaver with a flat panel or LCD screen not powering down the screen can actually decrease the lifetime of the display, since the fluorescent backlight remains lit and ages faster than it would if the screen is turned off and on frequently.product lifetime. In most cases, the tube is an integral part of the LCD and the entire assembly needs to be replaced. This is not true of LED backlit displays.

Thus the term "screen saver" is now something of a misnomer – the best way to save the screen and also save electricity consumed by screen would simply be to have the computer turn off the monitor. Screensavers displaying complex 3D graphics might even add to overall power draw.

After Dark was an early screensaver for the Macintosh platform, and later PC/Windows, which prominently featured whimsical designs such as "flying toasters". Perhaps in response to the workplace environment in which they are often viewed, many screensavers continue this legacy of whimsy by populating the idle monitor with animals or fish, games, and visual expressions of mathematics equations (through the use of fractals, Fourier transforms or other means) as in the Electric Sheep screensaver.

The screensaver is also a creative outlet for computer programmers. The Unix-based screensaver XScreenSaver collects the display effects of other Unix screensavers, which are termed "display hacks" in the demo scene.

On older versions of Microsoft Windows the native screensaver format had the potential to install a virus when run (as a screen saver was just an ordinary application with a different extension). When any file with the file suffix ".scr" was opened, for example from an e-mail attachment, Windows would execute the .scr (screensaver) file automatically: this had the potential to allow a virus or malware to install itself. Modern versions of Windows can read tags left by applications such as Internet Explorer and verify the publisher of the file, presenting a confirmation to the user.

On August 5, 2006, the BBC reported that "free screensavers" and "screensavers" respectively were the first and third most likely search terms to return links to malware, the second being BearShare.

By launching the "bubbles" screensaver executable through the bubbles.scr /p65552 command-line parameter, it runs as desktop wallpaper, the bubbles are smaller, and there are more bubbles on screen.

The screen savers were originally designed to save the CRT monitors from getting damaged by automatically changing the images on the screen during periods of user inactivity. With the advent of LCD monitors and technology improvements in modern CRT monitors, screen savers are no longer required to protect monitors from phosphor burn-in. A graphically more intensive screen saver will require more power than the normal screen.

For computers that support advanced power settings, applying power schemes by turning off the monitor on inactivity alone would suffice. You do not have to specifically turn off the screen savers. For computers that do not have an option to turn off the monitor, you can use the Registry Configuration in Endpoint Central to turn off the screen savers. Similar to applying power schemes, you first need to define the registry configuration, select the target computers/users and then deploy the configuration.

CTL display products are manufactured to rigorous standards. Our display products are consistently recognized as among the highest quality display products in the industry. Nevertheless, due to the nature of LCD technology, an LCD display may exhibit a small number of very small bright or dark spots on the screen. Often, these spots are noticeable only when the screen continuously displays a certain solid color such as an all-white or all black background. This type of background can be present when initially turning a computer on, or when a computer switches the display to a specific screen-saver.

An LCD display is made up of tens of thousands of individual pixels, and each pixel is made up of 3 individual sub-pixels (red, blue and green). In-fact, a 17" LCD has over 1,300,000 pixels and almost 4 million sub-pixels! Each sub-pixel is controlled by an individual transistor which turns the individual sub-pixel that it controls either on or off to create the image on your screen. An anomaly occurring during the manufacturing process can cause an individual transistor to continuously light or fail to light an individual pixel element, causing one of these small spots on the screen. Although this anomaly occurs relatively rarely in individual transistors, there are millions of sub-pixels on each LCD screen, and it is not uncommon for an LCD screen from any manufacturer to contain a few of these transistor anomalies and their associated bright or dark spots. For a manufacturer to sell only LCD""s with no transistor anomalies would result in a prohibitive cost to you, the consumer…one many times higher than it is today. Most people and applications are tolerant of a small number of these transistor anomalies on an LCD screen, and prefer the lower cost of LCD""s that existing standards allow.

CTL sets simple & strict limits as to the allowable number of non-performing pixels or sub-pixels on our LCD display and laptop computer screens. These criteria supplement our existing Warranty and are applicable during the warranty period for all CTL and 2go LCD displays as follows:

The LCD display of products under warranty will be replaced if CTL determines that it has 6 or more bright sub-pixels, 6 or more dark sub-pixels or a combination of 6 or more bright and dark sub pixels.

Hi - I thought this was the case, but I recently purchased a Samsung LCD TV/Monitor and text below is from their website... Presumably most users are going to have their screens turning off after a period of inactivity but it"s worth knowing care may still

Although much less susceptible than Plasma TVs, LED TVs are still subject to screen burn in (image retention). In general, you should avoid keeping a static picture (that is, a picture that contains no or few moving elements)

or a picture with static elements (black bars, black borders, logos, etc.) on your LCD TV for more than two hours at a time. If, for example, you have your TV set to 4:3, and have black borders on the top and bottom, or on the sides, changing the picture size

for a minute or two every couple of hours, say during commercials or in between shows, would decrease the chance of screen burn in. Reducing the brightness and contrast of the screen when it is displaying static elements will also decrease the chance of burn

LED TV for more than two hours at a time. Make sure you change the image on your screen periodically. Also, if you intend to leave your PC unattended for long periods of time, or you leave the same image on your screen while you work on other things for extended

periods of time, you should set up a screen saver that goes on after about twenty minutes, or set up your monitor so that it turns off if unattended for more than twenty minutes.
