TFT Kala Displei: Intafeis Fridom long 0.69 i go long 10.1 Ins

Stori

Februeri 25, 2024

Wanpela monokrom LCD i save painimaut sapos wanpela samting i stap ples klia. Wanpela TFT i save stretim sapos em i ken yusim. Difrens i kamap long 'error rate', long hamas hariap wanpela opereta i ritim wanpela graf, na long hau prodak i luk olsem nau.

Stat long yu ken lukim i go long yu ken yusim

Wanpela monokrom LCD i save painimaut sapos wanpela samting i stap ples klia; wanpela TFT i save stretim sapos em i ken yusim. Active matrix i givim wanwan piksel draiv bilong em yet, we i save muvim kontras, bekim na kala i go antap long wanpela oda bilong mak, na i mekim ol aikon, jat, ful Saina leit na tats olgeta i kamap. Human-machine interface i save go long wanpela panel we i soim tupela lain bilong teks i go long wanpela windo we i ken ranim wanpela intafeis.

Difrens i pundaun stret long prodak. Ol yusa i stop long tingim ol bikpela kod, ol 'error rate' i go daun, ol wokman i ritim ol graf hariap moa long ol namba, na prodak i luk moa moden bikos em inap long droim piksa. Sapos yu tromoi liklik mani moa long ol 'hardware' dispela bai senisim olgeta samting long sait bilong ekspiriens — na dispela i as na ol kala intafes i wok long lusim ol bikpela prodak na i go long ol bikpela prodak.

Yu mas makim 'interface' long sistem, na i no long 'fashion'

TFT intafeis seleksen em i olsem wanpela 'gearbox': i no gat gutpela opsen, wanpela tasol i wankain. MCU intafes i yusim liklik pin na em i isi long draivim, i gutpela long ol liklik MCU na ol non-hai-spid yus, tasol yu yet i mas lukautim wanpela freim bafa. Parallel RGB i save transfer hariap na i stret long vidio na animesen, tasol i save yusim planti pin na i no gutpela long ol longpela ran. SPI em i liklik tru — liklik lain tasol i save lukautim liklik kala panel — wantaim liklik 'refresh' tasol. LVDS na MIPI i save karim hevi na longpela ran, na i stret long ol bikpela sais na ol ples we i gat pawa.

Yu ken makim 'interface' long wanem samting 'host' bilong yu inap long givim, hamas spes bilong 'routing' yu gat insait, na hamas konten yu mas 'refresh'. Setim dispela tripela na 'interface' i stap gut tru. Ol solusen bilong mipela i larim ol i stretim 'interface', 'voltage' na 'pin definition' long disain, olsem na sistem bilong yu i no gat wok long kisim wanpela hap bilong katalog.

0.69 i go long 10.1 ins long wanpela pletfom

Wanpela bikpela sais span i gat gutpela pe tru. Sapos prodak lain bilong yu i karamapim ol liklik hanheld divais na ol intaektiv panel, na ol displei modul i kam long wanpela saplaia, orait draiva kod, asembli proses na saplaia menesmen olgeta i wankain, na ekspiriens bilong enjiniaring i ken yusim gen. Wanpela kros-saplaia kombinesen i save min olsem tupela draiva set, tupela inspeksen rejim na tupela wei bilong wok.

0.69-inch liklik kala panel i save helpim ol liklik masin na ol samting bilong werim; 2.4, 3.5, 4.3, 5.0 na 7.0 ins i karamapim ol bikpela hanheld na panel aplikesen; 10.1 ins i save helpim ol intafeis na ol infomesen bod. Yu ken putim 'touch' long hap we i gat nid, na yu ken senisim kala bilong 'cover-lens' na 'backlight'. Dispela sais lain i karamapim ol nid bilong soim planti ol 'hardware' prodak na i no senisim saplaia namel long taim.

Kastomaisesen i no go daun bikos em i gat kala

Ol i save ting olsem ol kala panel em i wanpela standet-prodak maket, tasol spes bilong stretim em i bikpela olsem bilong monokrom. Sais i ken i no stret, 'interface' na 'pin definition' i bihainim disain, longpela bilong FPC na rot bilong lusim kebol i bihainim 'assembly', 'backlight brightness' na kala i bihainim envairomen, 'temperature grade' i bihainim ples, na 'viewing direction' i bihainim ples bilong putim. Ol i ken makim tu 'touch technology' ('resistive' o 'capacitive') na 'cover-lens process'.

Long praktis, givim mipela resolusen, intafes kondisen, asembli sais, opereting envairomen na tats rikwaemen, na wok bilong bungim em saplaia i mekim. Mipela i givim bek wanpela solusen na kwotesen insait long tupela ten foa aua; ol paramita em ol 'catalog values' na 'customization' i bihainim disain bilong yu. Ol kala panel i ken kamap long droim tu, i no long kisim tasol long wanpela katalog — we i sevim bikpela hap taim long ol liklik projek.

Bihain long Intafeis: Frem Bafa na Memori

Ol manmeri i save luksave long 'interface choice', tasol samting we i save pasim TFT projek em 'frame buffer'. Wanpela 240 long 320 RGB565 displei i nidim samting olsem 150 kilobait long wan wan freim. Sapos host maikrokontrola i gat liklik RAM moa long dispela, disain i ken pundaun i go long liklik kala dip, draivim panel i go long wanpela serial intafeis we i no nidim wanpela lokol freim bafa, o putim wanpela ekstenel memori na wanpela kontrola we i menesim 'refresh'. Em i no gutpela long mekim disisen long dispela bihain long ol i redim 'circuit'; long mekim disisen long taim bilong seleksen em i wanpela telefon kol.

Refresh rate i save wok wantaim em tu. Wanpela paralel o RGB intafeis i save subim ol freim hariap tasol i save kisim planti MCU 'bandwidth'; SPI i luk ekonomik inap long taim yu skelim taim bilong trensfer long mak bilong freim reit na painim olsem prosesa i no gat taim moa long mekim narapela samting. Mipela i skelim 'interface' wantaim RAM na klok bilong 'host controller', na mipela i tokaut long 'frame rate' we mipela i ken winim insait long proposal na i no larim ol i painim aut long taim bilong bringim i kam antap.

Taim yu makim 'interface' dispela i makim hamas rum MCU i lusim

Planti tim i save makim MCU pastaim na skrin namba tu, na sapos ol i senisim oda, dispela i save daunim ol opsen hariap. RGB na LVDS/MIPI intafeis i nidim host long karim wanpela displei kontrola we i wankain; SPI em i bilong olgeta hap tasol 'frame-rate' bilong en i no bikpela tumas. Bihain tasol long MCU i stret, em i kamap olsem 'target refresh rate' i no inap long stap, o 'pin count' i sot, na disain i go bek.

Oda bilong krai em long stretim ol mak bilong soim long ol samting we prodak i laikim — 'frame rate', resolusen, kala dip, sapos yu mas tatsim — na kisim 'interface' na MCU long ol dispela samting. Long ol prodak we i gat ol aikon na teks, wanpela SPI o MCU intafeis long wanpela modul wantaim wanpela besik kontrola em inap; ol 'curve', 'video previews' na 'dynamic charts' i nidim RGB o 'high-bandwidth interfaces'.

Mipela i skelim 'interface' na 'frame rate' wantaim ol samting bilong klaien na MCU pletfom, na mipela i save givim ol 'frame rate' we mipela i skelim. Sapos yu painimaut olsem em inap ran hariap tru pastaim long yu mekim wanpela resolusen, dispela bai abrusim wanpela raun bilong makim gen MCU.

TFT LCM wantaim Capacitive Touch: Wanem samting i senis long intafes

Sapos yu putim wanpela 'capacitive touch layer' long wanpela TFT LCM, dispela i save senisim tripela samting moa long panel. Namba wan em i 'electrical interface': displei i ken stap yet olsem RGB, SPI o MIPI, tasol 'touch controller' i save kam bek long I2C o SPI olsem namba tu divais, olsem na host i nidim namba tu bas na namba tu 'interrupt line'. Namba tu em i 'stack': wanpela 'cover glass', 'touch sensor', 'display' na wanpela 'optical bond', na olgeta wan wan 'interface' namel long tupela em i wanpela ples we wanpela 'bubble' o wanpela 'misalignment' inap kamap. Namba tri em i 'firmware' - 'touch controller' i nidim 'configuration' bilong em yet na, sapos yu yusim wantaim 'gloved' o 'wet-finger', 'tuning' bilong em yet.

Dispela em i ples tu we ol saplaia i no wankain. Wanpela TFT LCD module saplaia long Saina we em i gutpela tru bai salim I2C adres bilong 'touch controller', piksa bilong kava glas, 'bonding specification' na wanpela 'sample' we i bin stap laip long wanpela 'temperature cycle', na ol i no askim em tupela taim. Wanpela we i wok long treding tasol bai salim 'panel datasheet' na kolim prais. Dispela tes em i no gat bikpela pe: askim long 'touch configuration file' na lukim hamas taim em i kisim long kamap.
