Ngokuthuthuka okusheshayo kwe-Global Flat Panel Display Display (FPD), izinhlobo eziningi ezintsha zokubonisa, ezifana nesibonisi se-liquid Crystal (LCD), iphaneli yokubonisa ye-Plasma (PDP), njalonjalo. Phakathi kwazo, izikrini ze-LCD zisetshenziswa kabanzi kwizisombululo zokuthinta ngenxa yezinzuzo eziphakeme zokukhanya okuphezulu, ama-engeli amakhulu okubuka, imibala ecebile, kanye nokusetshenziswa kwamandla okuphansi.

Isikrini se-LCD luhlobo lwedivayisi ye-phenomenon ekhiqizwa umphumela wokujikeleza obonakalayo wama-molekyuli e-crystal awuketshezi. Umgomo oyinhloko ukusebenzisa umphumela wokujikeleza obonakalayo wento ethile (i-liquid crystal into) kanye nomgomo wokuthi ama-molecule e-crystal ashintshile azoshintsha amalungiselelo awo enkundleni kagesi ukuze alawule ukuqina kokukhanya okugcwele, ukuze kufinyelelwe inhloso yokubonisa. I-TFT-LCD (Ifilimu elincanyana le-transistor liquid Crystal Display) lingenye yezindlela eziningi ze-Crystal Ekhombisa, zisebenzisa ubuchwepheshe be-Film Transistor Technology ukuthuthukisa ikhwalithi yesithombe.

Ngoba impahla ye-crystal ye-liquid esikrinini se-LCD ayizikhanyisolo, kudingeka umthombo owengeziwe wokukhanya, ngakho-ke kukhona amashubhu ama-light ezinhlangothini zombili zesikrini sokubonisa, futhi inani lamashubhu wamathabhula ahlobene nokukhanya kwesibuko se-LCD. Isibonisi sokuqala se-crystal esisekuqaleni sasinamashubhu wesibani amabili aphezulu futhi aphansi, futhi kamuva wathuthukisa indlela yezibani ezine namalambu ayisithupha. Kukhona iphaneli yokukhanya e-backlight (noma iphaneli yokukhanya eyunifomu) nefilimu ekhanyayo ngemuva kwesibonisi se-crystal ewuketshezi. Iphaneli yesightlight yakhiwa izinto ze-fluorescent futhi ingakhipha ukukhanya nomsebenzi oyinhloko wokuhlinzeka ngomthombo wokukhanya wangemuva ofanayo. Ngezibonisi zekristalu eziwuketshezi, ukukhanya kuvame ukuhlobana nomthombo wayo wokukhanya wangemuva. Umthombo ogqamile umthombo wokukhanya wangemuva, ukukhanya kwalo lonke i-LCD kuzokhula ngokufanele.

Ukukhanya okuphambi kwesikrini kusho amandla akhanyayo endaweni ngayinye yeyunithi (into ekhanyisiwe), futhi iyunithi yalo yokulinganisa), i-Nit), okungukuthi, iCandela Square (ebizwa nge-CD / M²). Izikrini ze-LCD zanamuhla zisebenzisa amafilimu wokuqhakambisa okukhanya okukhanya okubonakalayo, okwandisa inani lamalambu, nokwandisa amandla amalambu ukukhulisa ukugqama okubonakalayo ngezinga elikhulu.

Njengamanje, ukugqama kwezikrini eziningi ze-LCD emakethe kucishe kube ngu-300-500CD / m². Ama-TouchDisplays angenza ngezifiso ama-degree ahlukene wokukhanya okuphezulu ngokuya ngendawo yokusebenza komshini, kuze kufike ku-2000cd / m². Ukubonakala ngokucacile ngaphansi kokukhanya okuqinile kwangaphandle, izixazululo ezenziwe ngezifiso zingasanelisa izimfuno eziningi zabathengi. Ngaphezu kwalokho, ukuze uhlangabezane nezidingo zezinhlelo zokusebenza ezahlukahlukene zezimboni, ama-TouchDisPlays ahlinzeka ngezinketho eziningi zokwenziwa kwesikrini ezinjenge-machine materproof, anti-glare, nengilazi ephakeme.

EChina, emhlabeni

Njengomkhiqizi onolwazi olunzulu lwezimboni, ama-touchdisplays athuthukisa izixazululo eziqondakalayo ezihlakaniphile. Kusungulwe ngonyaka we-2009, ama-touchdisplays andisa ibhizinisi lawo emhlabeni wonke ekwakheniThinta wonke-in-one pos,Isiginali yedijithali esebenzayo,Thinta Qapha, futhiI-Electronic whiteboard exhumana nge-elekthronikhi.

Ngeqembu le-R & D engochwepheshe, inkampani inikelwe ukunikela nokwenza ngcono i-ODM egculisayo ne-OEM Solutions, ukuhlinzeka ngezinsizakalo zokuqala kanye nemisebenzi yokwenza ngokwezifiso zomkhiqizo.

Trust TouchDisPlays, wakhe umkhiqizo wakho ophakeme!
