Tekinoroji yekugadzira skrini yemapiritsi ine resolution yepamusoro
Kugadzirwa kwemapiritsi mumakore gumi apfuura kwakabatana zvikuru nekufambira mberi kwetekinoroji yekuratidzira. Kune vashandisi, sikirini ndiyo "chiso" chemudziyo: nzvimbo yavanoverenga, vanodhirowa, vanoona, uye vanoshanda. Nokudaro, vagadziri vari kumhanya-mhanya kuti vape magirazi epiritsi ane resolution yepamusoro, akajeka, ane ruvara rwakarurama, asingashandise simba zvakanyanya, uye akasununguka kushandisa kwemaawa akawanda. Kumashure kwezviratidziro izvi zvinoshamisa kune nhevedzano yakaoma yemaitiro ekugadzira zvinhu uye ekugadzira - kubva pakugadzira mapaneru uye masisitimu ekugadzirisa mavara kusvika pakuyera mavara uye kuyedzwa kwemhando.
1. Chii chinorehwa ne "high resolution" pa "tablet screen"?
Kugadziriswa kwechiso kunoreva huwandu hwemapikiseli anoumba mufananidzo (semuenzaniso, 2560 × 1600). Zvisinei, chinhu chinonyanya kukosha pakuona kwemaziso ipixel density (PPI—pixels per inch). Mapiritsi ane 10–11-inch screens uye high resolutions anowanzova nePPI kana kupfuura, zvichikonzera rugwaro rwakatsetseka uye mitsetse isina kujeka. Kuti vawane high resolutions, vagadziri vanofanirwa kugadzira ma pixel structures madiki uye akasimba, vasingakanganisi kupenya, kushanda nesimba, kana kururama kwemavara.
2. Sarudzo yeTekinoroji yePanel: LCD vs OLED
Kune mhuri mbiri huru dzetekinoroji mumapiritsi emazuva ano:
a) LCD (Kuratidzwa kweCrystal yeLiquid)
MaLCD haaburitse chiedza chawo ega. Mapaneru eLCD anoda mwenje wekumashure kuti avhenekere jira regirazi remvura uye mafirita emavara. Mhando dzakajairika:
– IPS (In-Plane Switching): maangles ekuona akafara uye mavara akagadzikana, anozivikanwa pakati pemapiritsi emhando yepamusoro.
– LTPS LCD (Low-Temperature Poly-Silicon): inobvumira ma transistors anokurumidza uye akasimba, inotsigira resolution yepamusoro uye mwero wekuzorodza wakakwira.
– IGZO (Indium Gallium Zinc Oxide): inoshanda nesimba uye inokwanisa kuchengetedza huwandu hwemapikiseli akawanda nekubuda kwemhepo kwakaderera.
b) OLED (Diode Inoburitsa Mwenje Wechisikigo)
MaOLED anoburitsa chiedza: pixel yega yega inoburitsa chiedza chayo. Zvakanakira zvawo zvinosanganisira kusiyana kukuru, matema akadzika, uye kupindura nekukurumidza. Zvisinei, kugadzirwa kwawo kwakaoma zvikuru, kunyanya mukuwana kufanana, hupenyu hwese, uye kushanda zvakanaka pamazinga echiedza chakakwirira.

3. Backplane: Hwaro hwePixel Control
Muzviratidziro zvine resolution yepamusoro, backplane (chikamu cheTFT transistors chinodzora subpixel yega yega) ine basa rakakosha. Resolution yakakwira, ma transistors akawanda anofanira kuiswa munzvimbo imwe chete. Saka, zvinhu zvakanyatsonaka uye maitiro e lithography zvinodiwa.
Mhando dzema backplane dzakajairika:
– a-Si (silicon isina chimiro): mutengo wakaderera, asi kufamba kwemaerekitironi kwakaderera saka hazvina kunaka kune ma resolutions akakwirira kana kuti high refresh rates.
– LTPS: kufamba kwakanyanya, kwakanaka kuti munhu agone kupindura nekukurumidza.
– Oxide TFT (semuenzaniso IGZO): inopa chiyero chakanaka chekushanda zvakanaka, huwandu uye kushandiswa kwesimba.
Kugadzirwa kwemusana kunosanganisira maitiro akafanana neari muindasitiri ye semiconductor: thin-layer deposition, photolithography, etching, uye kuumbwa kwemaitiro emagetsi asingaonekwe.
4. Kuita kuti maSubpixels ave madiki
Pikseli imwe chete ine ma subpixel matsvuku, magirini, uye bhuruu (RGB). Pakugadziriswa kwepamusoro, subpixel yega yega inofanira kunge iri diki uye yakanyatsojeka kudzivirira kuputika kwemavara kana kusaenzana. Dambudziko:
- chengetedza daro riri pakati pema "subpixels" akafanana (pixel pitch),
- iva nechokwadi chekuti subpixel yega yega inowana magetsi/voltage yakakodzera,
- kuderedza kubuda kwechiedza (paLCD) kana kubuda kwemagetsi (paOLED).
MumaLCD, subpixel pattern inoumbwa uchishandisa color filter ne light-blocking layer (black matrix). MumaOLED, subpixel pattern inobatanidzwa nenzira ye organic material deposition, yakaita se fine metal mask (FMM) kana mamwe matekiniki ari kugara achigadzirwa.
5. Ruvara rwekumashure uye kudzima kwenzvimbo paLCD
Nekuti maLCD anoda backlight, mhando ye backlight yakakosha pakuita kuti screen ijeke uye ive yakajeka. Matekinoroji anoshandiswa kazhinji anosanganisira:
– Yakavhenekerwa nemucheto: Ma LED anoiswa padivi pepanhi, uye chiedza chinoparadzirwa kuburikidza neplate yemwenje inotungamira. Yakatetepa uye yakachipa, asi kudzima kwenzvimbo kwakaderera.
– Ma LED ari kuseri kwepaneru, zvichibvumira kudzora nzvimbo yechiedza zviri nani.
– Mini-LED: inoshandisa zviuru zvema LED madiki semwenje yekumashure kuwedzera kusiyanisa kuburikidza nekudzima kwenzvimbo kwakanyatsonaka.
Kune mapiritsi ane resolution yepamusoro, mini-LED iri kuwana mukurumbira muchikamu chepamusoro nekuti inogona kusvika paOLED contrast uku ichiramba ichipenya zvakanyanya—inobatsira pakushandisa HDR uye pakushandisa panze.
6. Optical Layer: Polarizer, OCA, uye Anti-Reflection
Kupinza hakuonekwi chete nehuwandu hwemapikiseli, asiwo nekuti chiedza chinopfuura sei nepakati pemachira echiedza. MumaLCD, mapolarizers anodiwa kuti makristaro emvura agone kuchinja chiedza. MumaOLED, chimiro chechikamu chacho chakaomawo, kusanganisira machira anodzivirira uye anodzikamisa.
Kuderedza kutarisisa uye kuvandudza kuverenga:
- chifukidziro chinodzivirira kupenya (AR) chinoshandiswa,
- anti-fingerprint (AF) tekinoroji,
- uye OCA (Optically Clear Adhesive) yekunamira skrini negirazi.
Zviratidziro zvakazara zvinoderedza "mukana wemhepo," saka mifananidzo inoonekwa iri pedyo nepamusoro uye parallax inoderedzwa - zvakakosha pamapiritsi anoshandisirwa stylus.
7. Magadzirirwo eGirazi Rinodzivirira uye Kusimbisa
Mapiritsi anovhara magirazi akasimba asi akatetepa. Girazi reAluminosilicate, rakasimbiswa kuburikidza nemaitiro ekusimbisa makemikari (kuchinjana kwemaion), rinowanzoshandiswa. Mukuita uku, maion madiki ari pamusoro pegirazi anotsiviwa nemaion makuru (akadai sepotassium), zvichiita kuti pave nekumanikidzwa kunowedzera kuramba kutsvedza nekukwenya.
Uye zvakare, vagadziri vanofunga nezve:
- ukobvu hwegirazi (hunokanganisa huremu hwekunyora uye kunzwa),
- kuenderana nepenzura,
- pamwe chete nemhando yejira rinokuvadza bvudzi kuti rideredze kusvibiswa kweminwe.
8. Kubatanidzwa kweStylus yeKubata neDigitizer
Mapiritsi emazuva ano anowanzo shandisa ma touchscreen e capacitive. Pamidziyo inotsigira mapeni, pane chinhu chinotsigira mapeni (senge electromagnetic kana active capacitive). Kubatanidzwa uku kunofanirwa kuitwa pasina kukanganisa mashandiro ekuona:
- grid ye sensor inofanira kunge yakanyatsonaka kuitira kuti isaonekwe,
- kupindira kwemagetsi kunofanira kudzorwa,
