Puas pixels rau cov saib. Hauj lwm muaj qhov teeb meem thiab txoj kev mus rau tshwj kom txhob nws.

Niaj hnub no, cov neeg siv uas niaj hnub cuab yeej siv thiab lub computer cov khoom, cov lus "tuag pixels" tsis muaj dab tsi tab sis mob taub hau thiab phem moods, tsis ua. Tab sis dab tsi no yeej yog thiab yuav ua li cas txaus ntshai nws yog, yuav tsum tau "zoo siab" tswv ntawm cov kos duab nrog cov tib ntaus pixels?

Rau starters, cia saib, niaj hnub TVs thiab saib ua hauj lwm rau hauv paus ntsiab lus. Kua siv lead ua qhia ntawv muaj ib tug duab los ntawm ib tug plurality ntawm cov ntsiab lus uas yog hu ua pixels. Thaum lawv hloov lawv xim, cov duab nyob rau hauv screen yog tseem hloov, thiab peb muaj peev xwm saib tam sim no cov duab ntawm cov ntsiab lus. Nyob rau hauv niaj hnub saib ntsia matrix, hu ua active - nyob rau hauv nws rau cov kev tswj ntawm txhua pixel raws li ib tug tib nyias zaj duab xis transistor (uas yog vim li cas xws cov ntxaij vab tshaus yog hu ua TFT, los ntawm cov lus Askiv Nyias Zaj duab xis Transistor). Yog hais tias ib tug ntawm cov transistors rau ib co yog vim li cas tsis, peb yuav soj ntsuam cov phenomenon, uas yog hu ua tuag pixel nyob rau saib.

Vim ib tug kev malfunction ntawm lub transistor, xws cov ntsiab lus yeej tsis hloov lawv cov xim thaum lub sij hawm ntawm qhov kev tshuaj ntsuam duab thiab hloov yog cov dub teev. Txawm hais tias nws yuav tsum tau borne nyob rau hauv lub siab hais tias tuag pixels yog tsis tsuas dub - nyob rau hauv ib tug dub keeb kwm yav dhau yog ib tug taw tes feem ntau yog dawb, thiab muaj yog xim liab, xim xiav thiab ntsuab pixels yog faulty. Xws li ib tug tsis ua hauj lwm nyob rau hauv peb lub sij hawm yuav kho los ntawm ib tug kws rhiav. Ua li no, koj yuav tsum hloov cov ua tsis tau tejyam coj transistor, thiab nws yog dua tau nqa tawm lawv zog.

Tab sis nws thiaj li tshwm sim uas cov neeg tuag pixels ntawm qhov screen yog tsis tsim vim lub tsis ua hauj lwm ntawm lub transistor, thiab ua tsaug rau qhov thiaj li hu ua daig pixels. Feem ntau jam nrog lub tsos ntawm lub teeb dots rau tsaus nti tom qab, uas tsis hloov nws cov xim nyob rau hauv txhua yam. Xws li ib tug kho raws, raws li txwv mus rau "dub me ntsis", koj muaj peev xwm sim kho nws thiab nyob hauv tsev nrog cov kev pab los ntawm ib co cev los yog software manipulation.

Nws yuav tsum tau muab sau tseg tias ua manufacturers yog tam sim no teem cai tshwj xeeb uas tso cai rau ib tug tej yam muaj pes tsawg tus ntawm puas pixels nyob rau hauv matrices tsom kwm ntau yam qauv. Qhov no yog vim, feem ntau, mus rau lub fact tias cov feem pua ntawm kev sib yuav ntawm cov matrices kev khiav hauj lwm nyob rau hauv cov kua muaju, heev yog siab. Qhov no nuance yuav tsum tau them nyiaj mloog rau yog tias koj yeej yuav tau mus thov kev kho nyob rau hauv warranty. Rooj pub puas pixels muaj nyob rau hauv tus txheej txheem hu ua «ISO-13406." Nws yuav muab tau yooj yim nyob rau hauv Internet ntawm ntau ntawm cov kev manufacturers ntawm LCD saib.

Muaj coob tus neeg feem ntau cov nqe lus nug tshwm sim: yuav ua li cas nyuaj nws yog los saib tuag pixels nrog tus liab qab qhov muag? Teb nws kom meej meej yog tsis zoo li mus kawm tau ntawv zoo. Qhov no yog vim lub fact tias thaum twg koj yuav ib tug saib cov neeg muag khoom feem ntau qhia peb txoj kev kaj lug hloov cov dluab, tsis tas li ib tug zoo zoo nyob rau hauv cov zaub nyob rau hauv ib tug ntau yam ntawm lub tiaj haiv. Piv txwv li, nws tshwm sim hais tias ib tug puas taw tes liab yuav pom tsuas yog nyob rau ib tug ntsuab keeb kwm yav dhau, thiab ces tsuas nyob rau hauv tej yam Hawj txawm. Yog li ntawd, saib koj purchase yuav tsum tau ceev faj heev. Qhov no yuav ua tau nrog cov kev pab los ntawm kev kawm tshwj xeeb. Ib tug ntawm qhov zoo tshaj plaws ntawm cov cuab yeej yog «Nokia saib Test», uas tso cai rau saib mus ntsuam xyuas rau lub xub ntiag los ntawm ntau yam xws luag, readability, moire thiab puas pixels.

Tsis txhob hnov qab tias qhov thiaj li hu ua tuag pixels daig (tsis muaj dub tsuas me me, thiab xim), koj muaj peev xwm sim "kho" nyob rau hauv lub tsev. Ua li no, koj muaj peev xwm siv kev kawm tshwj xeeb (ib tug ntawm qhov zoo tshaj plaws ntawm cov cuab yeej no hu ua «ScreenFix Deluxe») los yog sim promassirovat puas zaub cheeb tsam nrog ib tug paj rwb kua ntswg. Qhov loj tshaj plaws nyob rau hauv no "massage" yog tsis overdo nws, vim hais tias lub sij hawm ntawm ntxiv kev puas tsuaj rau lub zaub los yog lub anti-paab txheej yog heev loj.
