Ma maqashay wax ku saabsan shaashadaha? Ma garanaysaa waxay yihiin iyo waxa ay ujeedadoodu tahay? Maxaan ugu yeernaa shaashadaha ka dib dhan? Miyay badbaadiyaan shaashadahayada? Waxaan sameynay xoogaa cilmi baaris ah, waxaana ogaannay in, inkasta oo caan ah in ka badan toban sano ka hor, sababtoo ah isbeddelka tiknoolajiyada kormeerka, ereyga Screen Saver wuxuu noqday mid khaldan sannadihii u dambeeyay. Aynu aragno sababta ay taasi u dhacday iyo sidoo kale sababta aad weli u rabto inaad isticmaasho shaashad-baare:

Waa maxay Screensaver?

Screensavers waa barnaamij kombuyuutar loogu talagalay in lagu banneeyo shaashadda ama lagu buuxiyo muuqaallo dhaqdhaqaaq leh marka aanad isticmaalayn. Ujeeddadoodii asalka ahayd waxay ahayd inay ka hortagaan gubashada kombuyuutarrada da'da weyn, taasina waa sababta loogu yeero "screensavers." Gubashada hadda maaha arrin khusaysa kormeerayaasha casriga ah, laakiin dadku wali waxay ku dheggan yihiin shaashadaha sababtoo ah way jecel yihiin iyaga oo u isticmaali kara inay qariyaan macluumaad kasta oo xasaasi ah oo ku hadhay shaashadda.

Maxay ahayd ujeedada asalka ah ee kaydiyaha shaashadda?

Si aad u fahamto waxa ay yihiin shaashadaha iyo in aad jawaab u hesho su'aasha "waa maxay ujeedada aasaasiga ah ee shaashadda?" ^{("what is the primary purpose for a screensaver?")}, marka hore waa in aad wax ka barataa taariikhdooda. Carruur ahaan, mid ka mid ah barnaamijyadii xiisaha lahaa ee ugu horreeyay ee aan ku qancinnay waalidiinteena inay iibsadaan waxay ahayd barnaamijka muraayadda mugdiga^{(After Dark)} kadib. Tani waxay qayb ka ahayd sababta oo ah waxaanu samaynay cilmi-baadhisteena oo aanu fahannay in gubashada ay dhaawici karto kormeerayaashayada. Tani waxay ahayd xaalad si joogto ah u gubi karta sawirka muraayadda kormeeraha hore.

Si kastaba ha ahaatee, waxaan qiraynaa in sabab kale oo weyn oo aan u riixnay barnaamijkan waalidkayagu waxay ahayd inaan jecelnahay rootiga duulaya ee lagu soo bandhigay asalka muraayadda mugdiga kadib^{(After Dark)} . Shaashadahaani waxay ka mid ahayd kuwii ugu horreeyay ee loo sameeyay kombayutarada gaarka ah horraantii 1980-meeyadii ee Berkeley Systems . Tan iyo markaas waxa ay calaamad u ahayd isticmaaleyaasha kombuyuutarrada.

Markaa, waxaynu odhan karnaa sababta loo haysto shaashadaha waxay ahayd markii hore laba laab. Si rasmi ah, dadku waxay rabeen inay ka ilaaliyaan kombuyutarka qoyska inay gubaan. Marka labaad^{(Secondarily)} , dadku waxay jeclaysteen inay isticmaalaan sababtoo ah waxay ahaayeen kuwo madadaalo leh.

Waa maxay (waxay ahayd) gubashada?

Kormeerayaashii hore ee 198-tii waxay isticmaaleen tuubooyinka rayiga ee cathode ( CRTs ) si ay u shaqeeyaan. CRT^(CRTs) -yadu waxay u soo bandhigaan fosfoor gubanaya dhinaca kale ee shaashadda si ay u sawiraan sawir, iyo, si tartiib tartiib ah, gubashada waxay si joogto ah ugu shaqeysaa dhinaca dambe ee shaashadda. Ku daynta sawir wali taagan shaashadda waxay u oggolaanaysaa gubashada in si degdeg ah loo dejiyo. Tani waa waxa sababa in sawirka rooxaanta uu ka soo muuqdo TV-yadii hore iyo ATM-yada^(ATM) , iyo sidoo kale kormeerayaashii hore ee PC. Shaashada balasmada^(Plasma) ayaa sidoo kale si fudud ugu nugul gubashada fosfooraska. Si kastaba ha ahaatee, shaashadaha cusub ee sida LCD-yada^(LCDs) iyo LED^(LEDs) -yada ayaa iska difaaci kara gubashada.

Waa maxay sababta gubashada-gubasho aysan khatar sidaas u weyn u lahayn?

Ugu dambayntii, CRT^(CRTs) -yadu waxay ku jireen khatar yar oo gubashada marka loo eego moodooyinka hore sababtoo ah horumarka tignoolajiyada dahaarka ee loo adeegsaday si looga ilaaliyo shaashadda gubashada fosfooraska. Intaa waxaa dheer, midabada loo isticmaalo kormeerayaasha casriga ah ee CRT waxay caadi ahaan ka dhib yaraayeen oo ka dhalaalayaan monotoneskii hore loo isticmaali jiray, markaa khatarta gubashada ayaa si weyn hoos ugu dhacday.

Iyadoo taasi jirto, waxay kugu noqonaysaa naadir inaad wakhtigan ka hesho kormeeraha CRT oo iib ah dukaanka kombayutarka. Wali way jiraan, laakiin waxa laga yaabaa inaad samayso amar gaar ah si aad mid cusub u qabsato. Markaa, gubashada ma aha khatar weyn sababtoo ah dhammaan kormeerayaasha PC ee hadda jira waxay isticmaalaan shaashadaha LCD .

Muxuu yahay heshiiska shaashadaha LCD?

Shaashadaha LCD^(LCD) ma isticmaalaan fosfoor si ay u sawiraan sawirkooda, markaa ma jirto khatar ah in wax ku gubto shaashadda. Si kastaba ha ahaatee, ka tagista muraayada LCD^(LCD) ee ku shaqeeya wakhti dheer waxay dami kartaa iftiinka dambe ee fluorescent, taas oo keeni karta in muraayadda LCD^(LCD) ay sii yaraato wakhti ka dib. Ogsoonow in ay suurtogal tahay in shaashadda LCD ay ku dhacdo shay la yiraahdo adkaysiga sawirka^{(image persistence)} , kaas oo sawirku si ku-meel-gaar ah ugu xayiran yahay shaashadda LCD . Si kastaba ha ahaatee, hal dariiqo oo tan lagu saxo ayaa ah in la damiyo kormeeraha LCD hal maalin ama wax ka badan si loogu oggolaado inuu nasto, ama u dejiyo sawiradaada dambe si ay si joogto ah u wareegaan. Fikrad ahaan^(Ideally) , waxaad horeyba u soo dejineysay kaagaKormeeraha LCD^(LCD) habeen kasta, tani waa inaysan noqon arrin.

Shaashadaha waxyeello ma^(Are) u leeyihiin shaashadaha LCD?

Waxay noqon karaan. Xataa isticmaalka caadiga ah, inta badan muraayadaha LCD^(LCD) dhalaalkoodu hoos ayuu u dhacayaa wakhti ka dib, ka tagista kormeeraha oo wata shaashadaha ayaa kaliya dedejiya habkan. Iftiinka dambe ee fluorescent caadi ahaan waa qayb muhiim ah oo ka mid ah kulanka kormeeraha LCD . Marka ay aad u daciifto, waxa ugu fiican ee la sameeyo waa inta badan in la beddelo kormeeraha oo dhan. Si aad u caddaato, haddii aad ka tagto kormeeraha LCD-ga^(LCD) oo si isdaba joog ah habeen u socda, waxa laga yaabaa in aad mid cusub soo riddo goor dhow. Sababtaas awgeed, waxaa habboon in marka hore loo isticmaalo muraayadaha muraayadaha ujeeddooyin madadaalo ah. Teknoloojiyadayada hadda jirta, wax badan ma "badbaadiyaan" Waxa aad u wanagsan in muraayada LCD^(LCD) loo dejiyo si uu isu damiyo marka uu shaqo la'aantu ka tago muddo dheer.

Si aad u hubiso in shaashadda LCD-gaagu aanay u shidnayn si wasakh ah marka aanad isticmaalin, waa inaad sidoo kale hagaajisaa qorshahaaga korantada ee Windows , si uu muqaalku u damisan yahay wakhti hore.

Waa maxay sababta aad u isticmaali karto shaashadaha?

Isbeddelka ku yimi tignoolajiyada kormeerka awgeed, ereyga “screen Saver” waxa uu noqday hadal khaldan oo casri ah. Haddii uu qof ku weydiiyo su'aal sida "mid ka mid ah kuwan soo socda ayaa tilmaamaya sababta aad u isticmaali karto shaashadaha?" ^{("which of the following indicates why you should use a screensaver?")}Jawaabtu waa tan: shaashadaha ayaa wali wata codsiyo madadaalo ah ama ujeedooyin kala duwan oo utility sida socodsiinta software antivirus.

Si kastaba ha noqotee, qof kasta oo isticmaalaya kormeeraha LCD wuxuu badbaadin karaa maalgashigiisa in ka badan isagoo hoos u dhigaya marka uu shaqeynayo. Markaa, haddii aad leedahay muraayad LCD^(LCD) ah , waxa fiican inaadan isticmaalin muraayad-shareeye. Iyadoo markii hore loo isticmaali jiray ujeedooyin labadaba wax ku ool ah iyo madadaalo labadaba, hadda waa in loo isticmaalo oo kaliya madadaalo.

What is a screensaver and should you use one?

Have you heard about screensavers? Do you know what they are and what their purpose iѕ? Why do we сall them screensavers after all? Do they save our screens? We have done a bit of research and found oυt that, although popυlar more thаn a decade ago, due to сhanges in monitor technology, the term screen ѕaver has become a misnomer in recent years. Let's see why that happened аnd also why you might still want to use a screensaver:

What is a screensaver?

Screensavers are computer programs designed to blank the screen or fill it with moving images when you are not using it. Their original purpose was to prevent burn-in on older computer monitors, and that is also why they are called "screensavers." The burn-in is no longer an issue for modern monitors, but people still hang on to screensavers because they like them and can use them to hide any potentially sensitive info left on the screen.

What was the original purpose of a screen saver?

To understand what screensavers are and to get an answer to the question "what is the primary purpose for a screensaver?", you must first learn a bit about their history. As kids, one of the first fun programs we convinced our parents to buy was the After Dark screensaver program. This was partly because we had done our research and understood that burn-in could damage our monitors. This was a condition that could permanently burn an image into an older monitor's screen.

However, we admit that another big reason we pushed this program on our parents was that we were in love with the flying toasters featured in the original After Dark screensaver. This screensaver was one of the first created for personal computers in the early 1980s by Berkeley Systems. It has been a cult icon for computer users ever since.

So, we can say the reason for having screensavers was initially two-fold. Officially, people wanted them to protect the family computer's monitor from burn-in. Secondarily, people just liked to use them because they were fun.

What is (was) burn-in?

The old monitors of the 1980s used cathode ray tubes (CRTs) to function. CRTs expose burning phosphor to the other side of a screen to project an image, and, gradually, the burn works its way into the backside of a screen permanently. Leaving a still image in place on the screen allows burn-in to set in much more quickly. This is what causes the ghost image to appear on older TVs and ATM monitors, as well as old PC monitors. Plasma screens were also mildly vulnerable to phosphor burn-in. However, newer monitor screens like LCDs and LEDs are immune to burn-in.

Why is burn-in not such a significant risk anymore?

Eventually, CRTs were at a smaller risk for burn-in than older models due to advances in the coating technology used to protect the screen from the phosphor burn. Additionally, the colors used on more modern CRT monitors were typically less harsh and bright than the stark monotones used in the past, so the risk for burn-in significantly decreased.

Despite this, it is going to be rare for you to find a CRT monitor for sale in a computer shop at this time. They do still exist, but you might have to make a special order to get a hold of a new one. So, burn-in is not a significant risk because all current PC monitors use LCD screens.

What is the deal with LCD screens?

LCD screens do not use phosphor to project their image, so there is no risk of something getting burned onto the screen. However, leaving an LCD monitor powered on for long periods of time can wear out the fluorescent backlight, which can cause an LCD screen to become dimmer over time. Note that it is possible for an LCD screen to suffer from something called image persistence, in which an image temporarily gets stuck on an LCD screen. However, one way to correct this is by just turning off the LCD monitor for a day or so to allow it to rest, or setting your background images to rotate routinely. Ideally, you are already powering down your LCD monitor every night, and this should not become an issue.

Are screensavers harmful to LCD screens?

They can be. Even with typical usage, most LCD screens' brightness decreases over time, and leaving the monitor on with a screensaver only speeds up this process. The fluorescent backlight is usually an essential part of the assembly of an LCD monitor. Once it becomes too weak, the best thing to do is often to replace the entire monitor. To be clear, if you leave your LCD monitor running overnight repeatedly, you might be shelling out for a new one sooner. Because of this, it is advisable to use screensavers primarily for entertainment purposes. With our current technology, they do not "save" much. It is more efficient to have an LCD monitor set to power itself down when it is left idle for too long.

If you want to learn how to turn off your screensaver, read our guide on How to set and customize screensavers in Windows. To make sure your LCD screen does not remain turned on wastefully when you do not use it, you should also adjust your Windows power plan, so that the display is turned off sooner rather than later. Check out this tutorial for details: 13 Ways To Save Power By Tweaking Power Plans In Windows.

Why should you use a screensaver?

Due to changes in monitor technology, the term "screen saver" has become a modern misnomer. If someone asks you a question like "which of the following indicates why you should use a screensaver?", the answer is this: screensavers still have applications as either entertainment or for various utility purposes such as running antivirus software.

However, anyone using an LCD monitor can save their investment more by having it power down when idle. So, if you have an LCD monitor, it is better not to use a screensaver. While they originally were used for purposes both practical and fun, now they should only be used for fun.

Are you using a screensaver on your PC?

Do you still want to use a screensaver on your Windows computer? If you do, but you are not sure what screensaver to set on your PC, we have a few good ones to recommend for you in this roundup: Top 12+ best free screensavers for Windows. Or, if you prefer, you can create your own screensaver, using your own photos, by following the steps from this guide: How to create a screensaver with IrfanView, in Windows.
