Touch Screen kya hai aur ye kaise kaam karta hai?


Kya aap jaante hain ki Touch Screen kya hai (What is Touch Screen in Hindi) aur ye kaise kam karta hai? aap men se adhikatar log en Touch screen kaa estmal apne dainik jivan men karte rahte hain. enhen aap apne Smart Phones, Computers, Laptops, ATM Kiosk etyaadi men dekhte aaye hain aur jarur estmaal bhi kiyaa hogaa. enhen estmaal karnaa bahut hi aasaan hotaa hai bas aapko screen men touch (sparsh) karnaa hotaa hai koi bhi kaary karne ke lia. koi bhi system se interact karne ke lia traditional keyboard aur mouse ke jagah abhi ham en Touch Screen kaa upyog karte hain. aage es post men ham en Touch Screen ke vishay men aur achchhi tarah se chalia jaante hain.bhale hi ham en touchscreen kaa estmaal bahut din se kar rahe hon lekin ham men se aise bahut log hai jinhen abhi tak bhi ye nahin pataa ki ye aakhir kaam kaise karte hain. eske kitne prkaar hain aur ye dusre non-touchscreen device se behatar kaise hai. ye touchscreen dikhne men to ek display screen jaise hi hai lekin yah ek input device bhi hai. ye screen pressure ko lekar kaam karte hain kyunki ye pressure ko lekar jyaadaa sensitive hote hain, yahaan par user ek computer ke saath interact karne ke lia screen par mehjud pictures aur shabdon ko touch kartaa hai jisse us jagah men pressure create hotaa hai aur touchscreen us pressure ke anusaar kaam kartaa hai.
Iske istmal ke karan ab ye hamaare jivan ka ek hissa ban gaya hai aur ese ham pray sabhi display technology men estmal kar rahe hain. esalia aaj mainne socha ki kyun ne aap logon ko Touchscreen kyaa hai aur ye kaise kaam kartaa hai ke vishay men puri jaankaari prdaan karun jisse aapko bhi es technology ke vishay men jaankaari praapt ho. to phir binaa deri kiye chalia shuru karte hain aur jaante hain ki aakhir ye Touch Screen kyaa hotaa hai aur aapko kyun es behatrin technology kaa estmaal karna chaahia.
Touchscreen ek electronic visual display hotaa hai jise ki ek user apne ungaliyon ko screen ke upar touch karke control kar saktaa hai yaani ki apne kaam kar saktaa hai. ek touchscreen user ko system ke saath jyaadaa direct rup se interaction karne ke lia maukaa dete hain kisi mouse ke saath tulnaa men Touchscreens kaa estmaal ab etnaa common ho gayaa hai tablet computers, smart phones aur dusre mobile devices men ki ab manufactures jyaadaa se jyada devices men touchscreen kaa hi estmaal kar rahe hain regular screen ke badle.
Jahaan ham pahle Traditional input devices ke tor par computer systems men keyboards aur mouse kaa estmaal karte the, vahin pichhle kuchh varshon se ham en touchscreen technology ka estmaal bde paimaane men kar rahe hain computer yaa mobile system ke saath interact karne ke lia. eske saath abhi regular laptop aur desktop computers men touchscreen displays ke saath traditional input device kaa bhi estmaal karne ki suvidhaa prdaan kar rahe hain jisse users ke paas jyada options mehjud ho estmal karne ke lia.
Touchscreens kaa estmaal ham bahut se variety ke devices men karte hain jaise ki computer, laptop monitors, smartphones, tablets, cash registers, aur information kiosks men. kuchh touchscreens men to touch-sensitive input ke badle men infrared beams ki grid kaa bhi estmaal hotaa hai ungaliyon ke presence ko mahsus karne ke lia.
Touchscreen ki History
Touchscreen ke vishay men sabse pahlaa idea E.A Johnson ko aaya jo ki us samay Royal Radar Establishment, Malvern, UK men kam karte the late 1960s men. jankaron ka manna hai ki pahli touchscreen capacitive type ki thi, jise ki ham abhi apne Smartphone men estmaal karte hain.
Uske baad touchscreen ko lekar kar experiment kiye gaye aur phir san early 1970s ke samay, pahlaa touchscreen ko develop kiyaa gaya Frank Beck aur Bent Stumpe ke dvaaraa, jo ki us samay CERN men engineers the. es physical product ko pahli baar san 1973 men estmaal kiyaa gayaa thaa.
Vahin san 1971 men, touchscreen technology men ek nayaa kirtimaan Doctor George Samuel Hurst ne sthaapit kiyaa, jo ki us samay ek instructor the University of Kentucky Research Foundation men. unhonne ek touch sensor kaa aavishkaar kiyaa thaa jise ki unhonne ‘Elograph’ka nam diya tha. vahin san 1974 men, Hurst ne apne company Elographics ke saath milakar duniya ki sabse pahli real touchscreen taiyaar ki jismen ki transparent surface jaise feature tha.
Year 1977 men, lagaataar pryaason ke baad Elographics ne ek resistive touchscreen ko develop kiya aur use apne naam par patent bhi kiyaa. ye vahi resistive touchscreen technology thi, jo ki aaj touchscreen technologies ke tor par bahut prasiddh hai aur use ham aaj estmaal bhi kar rahe hain. ek baat jo bahuton ko pataa nahin hai vo ye ki pahli resistive touchscreen ko san 1975 men Samuel Hurst ke dvaaraa develop to kar liyaa gayaa thaa lekin use san 1982 tak n hi duniyaa ke saamne produce kiya gaya aur n hi estmal kiya gaya.

Types of Touchscreens
Yahaan par ham jaanne vaale hain ki ye Touchscreen ke kitne prkaar upalabdh hain aur hamaare lia kon saa prkaar behatar hai. vaise to kayi alag alag prkaar ke Touchscreen in hindi upalabdh hai lekin yahaan mainne sabse jyaadaa estmaal men laaye jaane vaale touchscreen ke vishay men jaankaari prdaan karne vaalaa hun.
Resistive
Capacitive
Surface Wave
Infrared
Resistive
Resistive touchscreens (jo ki philhaal sabse jyaadaa popular technology hai) aur jo ki ek “transparent keyboards” ke tarah hi hai jise ki Screen ke top men overlay kiyaa gayaa hotaa hai. ye resistive touch screen panel ke upar ek patli metallic electrically conductive ki coating hoti hai aur ek resistive layer bhi hotaa hai jo ki electric current men change paidaa kartaa hai jab koi touch event hotaa hai, matalab ki jab koi apni ungli se es screen ke upar touch kartaa hai tab esse jo halachal paidaa hoti hai usse current ke prbhaav men bhi badlaav aataa hai aur ese hi controller ke paas bhejaa jaataa hai processing ke lia. ye to thi eski technical details ab ese aasaan bhaashaa men samajhte hain.
Is resistive touchscreen men ek flexible upper layer jo ki conducting polyester plastic ki bani hoti hai vo ek rigid lower layer jo ki ek conducting glass hoti hai uske saath bonded hoti hai aur ek insulating membrane se hi separate hui hoti hai. jab aap screen ko press karte hain, tab aap us polyester ko force karte hain glass ko touch karne ke lia aur jisse ye circuit complete hoti hai — jaise ki jab aap koi keyboard ki key press karte hain. Screen ke bhitar stith chip aapke coordinates kaa pataa karti hai ki aapne kis jagah men us screen ko touch kiyaa hai.
Ye Resistive touch screen panels jyaadaa affordable hote baakiyon ke tulnaa men lekin ye keval 75% ki hi clarity prdaan karte hain aur ye layer ko aasaani se kisi sharp object se damage kiyaa jaa saktaa hai. Resistive touch screen panels bhi dusre baahri elements jaise ki dust yaa water se khraab nahin hoti hai.
Capacitive
Ek capacitive touch screen panel aise material se coated hoti hai jo ki electrical charges ko store karti hai. jab bhi panel ko touch kiyaa jaataa hai, tab ek chhoti hi maatraa men charge us point of contact ki aur draw hoi hai. Circuits jo ki panel ke corner men sthit hoti hai vo us charge ko measure karti hai controller ko saari jaankaari bhejti hai processing karne ke lia. ye Capacitive touch screen panels ko keval ungaliyon se hi touch karne se kaam kartaa hai aur plastic yaa koi dusri vastu se ye kaam nahin karti hain. eske saath ye Capacitive touch screens par dusre outside elements jyaadaa prvaah nahin daal sakte hain aur ye bahut hi high clarity ke hote hain.
Ye screens bahut se layers of glass se bane hua hote hain. eski inner layer electricity conduct karti hain aur thik vaise hi outer layer bhi, esalia effectively ye screen aisaa behave kartaa hai jaise ki do electrical conductors ke insulator ke vajah se separate hon, esalia ese ek capacitor bhi kahaa jaataa hai. jab ham apni ungli ko screen ke upar rakhte hain vaise hi aap uske electric field ko bhi change karte hain. en Capacitive screens ko ham ek se jyaadaa jagah men chhu sakte hain aur ye achchhe tarike se kaam bhi kartaa hai.
Surface wave
Surface wave technology men ultrasonic waves kaa estmaal hotaa hai jo ki touch screen panel ke upar se pass kartaa hai. jab aap panel ko touch, karte hain tab ek chhote portion ki wave ko ye absorb kar leti hai. yahi badlaav ultrasonic waves men hone se ye us touch kiye gaye sthaan kaa pataa kar leti hai aur controller ko information bhej deti hai processing karne ke lia. Surface wave touch screen panels abhi tak ki sabse advanced types hai baakiyon ke mukaable lekin ye baahri elements se aasaani se damage ho jaataa hai.
Infrared
Kisi intruder alarm men jaise magic eye beams kaa estmaal hotaa hai, thik usi tarah infrared touchscreen men LEDs ke grid pattern of LEDs aur light-detector photocells kaa estmaal hotaa hai. unhen screen ke opposite sides men arrange karke rakhaa jaataa hai. ye LEDs se infrared light nikalti hai jo ki screen ke front se aati hai — aap kah sakte hain ki ye ek invisible spider’s web ke jaise prtit hoti hai. agar aap screen ko kisi sthaan men touch karte hain tab aap un beams ke raaste men aate hain yaa rukaav daalte hain. Screen ke bhitar stith microchip ye calculate karti hai ki aapne un beams ko kahaan par interrupt kiyaa hai, aur us hisaab se controller ko information bhej deti hai processing karne ke lia. yahaan par ungaliyon ke alaavaa bhi agar aap koi dusre vastu se screen ko touch karen tab bhi aap ese estmaal kar sakte hain.
Aage main aap logon ko kuchh less-common touch screen technologies ke vishay men jaankaari prdaan karne vaalaa hun.
Dispersive Signal Technology:
ese san 2002 men 3M company ke dvaaraa introduce kiyaa gayaa thaa, esmen sensors aapke mechanical energy ko detect karte hain jab aap unhen touch karte hain. esmen stith Complex algorithms un data ko interpret karte hain ye pataa karne ke lia ki aapkaa location kahaan par hai, aur phir data ko controllers ke bhejaa jaataa hai.
Pros: ye jyaadaa Durable hote hain, bahaar ke elements se jyaadaa effect nahin hote hain, eski clarity bhi bahut excellent hoti hai aur esmen aap finger yaa koi dusri vastu kaa estmaal touch karne ke lia kar sakte hain.
Cons: prarambhik touch ke baad, eski system ko aapke motionless finger ko detect kar pana thoda muskil hota hai.
Acoustic Pulse Recognition:
es system ko san 2006 men release kiyaa gayaa thaa Tyco International’s Elo division ke dvaaraa. esmen transducers kaa estmaal hotaa hai jo ki screen ke aaspaas stith hote hain aur jo ki vibration ko electrical energy men convert karte hain algorithms ke dvaaraa aur ye esi tarah se hi location kaa anumaan lagaate hain.
Pros: eski durability aur clarity achchhi hoti hai, ye baahri elements se jyaadaa prbhaavit nahin hoti hai aur ye large display men jyaadaa well-suited hote hain.
Cons: ye ek motionless finger ko detect nahin sakti hai.
Optical Imaging:
Image sensors (cameras) jinhen ki screen ke edge men rakhaa jaataa hai vo infrared black lights ko aasaani se pick kar sakte hain jo ki screen ke opposite side men present hote hain.
Pros: ye Scalable, versatile, affordable hote hain aur enhen large displays men bhi estmaal kiyaa jaa saktaa hai.
Resistive aur Capacitive Touch Screen men kyaa antar hai?
Yadi ham dekhen to touchscreens men mukhy rup se do prkaar ke hi touchscreens hi hain : Resistive aur Capacitive. ek aasaan tarikaa jo ki en donon touchscreen ke men antar bataa saktaa hai vo hai ki resistive touchscreen aapke ungaliyon ke touch ko “resists” karte hain, eske badle aapko ek stylus yaa electronic pen kaa estmaal karnaa hogaa screen ke saath vo bhi thodaa force lagaakar, kyunki agar keval screen ke upar ungli pher di jaaye tab usmen jyaadaa effect nahin hogaa. aap en resistive touchscreen ko supermarket men dekh sakte hain, jahaan par aap apnaa electronic signature prdaan karte hain apne bill pay karne ke lia.
Vahin ek capacitive touchscreen ko kuchh es prkaar se design kiyaa gayaa hai ki vo keval aapke finger’s touch se hi kaam kartaa hai. esalia aap en capacitive touchscreen kaa estmaal smartphone aur tablet men karte hain. esalia en displays kaa estmaal mukhy rup se consumer electronics men kiyaa jaataa hai.
Touchscreens kaise kaam karta hai?
Ek resistive touchscreen kuchh esaprkaar se kaam kartaa hai jiske baare men ham aage samajhne vaale hain/ Screen ke upar user ko touch karnaa hotaa hai aur es screen ke niche electrically conductive layer present hotaa hai. jab aap en display ko press karte hain tab aap ye feel karenge ki display thodaa bend hotaa hai. yahi ese kaam karne men madad karti hai. Touch karne se niche stith electric current men badlaav aataa hai jisse ye pataa chaltaa hai ki touch kahaan par huaa hai. uske baad ye sabhi jaankaari processing ke lia controller ko bhej detaa hai.
Aap Touch Screen kaa estmaal kaise karen?
Note: sabhi touchscreens ke samaan functions nahin hotaa hain, lekin yahaan par jo bhi actions ke vishay men mainne bataayaa hai vo bahut hi common function hain.
Tap – ek single touch yaa tap karne se screen ke upar apne ungli ke dvaaraa aap koi bhi app ko khol sakte hain yaa koi object ko select kar sakte hain. agar ham ese ek traditional computer ke saath tulnaa karen tab, ek tap kaa matalab hai apne mouse ke dvaaraa click karnaa hai.
Double-tap – ek double-tap se bahut saare alag alag functions ho sakte hain vo bhi us baat par depend kartaa hai ki aap use kis prkaar utilize karnaa chaahte hain. udhaaran ke lia agar ham ek photo ke upar double tap karte hain tab esse vo zoom ho jaataa hai.
Touch and hold – agar ham touchscreen ko Press aur hold karenge apne finger ke sahaaytaa se tab esse koi text select ho jaataa hai yaa koi object highlight ho jaataa hai.
Drag – agar aap koi object yaa icon ke upar press karte hain aur use hold karte hain tab esse aap use ek jagah se dusre jagah tak drag yaa khinch sakte hain.
Swipe – Screen ke upar Swip karne se aap photos ko badal sakte hain aasaani se. yaa phir esse screen ko kisi bhi dishaa men scroll bhi kar sakte hain.
Pinch – agar aap apne do ungaliyaan ko screen ke upar rakhen aur use pinch karen tab esse koi bhi jagah ko aap zoom in aur zoom out kar sakte hain.
