Tufuna amasimu okuva mu kkampuni z’amaduuka oluvannyuma lw’okuteeka ebipande byabwe okulemererwa. Omwezi oguwedde gwali mutimbagano gwa ddagala mu Midwest-emyezi 18 mu rollout, kitundu kyabweshelf-ebisenge by'empendabaali balaga omusaayi gwa backlight, era supplier eyaziguza "commercial grade" panels yali asirise ku warranty claims. Sikirini zaali bipande bya ttivvi z’abakozesa nga bizzeemu okuteekebwa mu biyumba eby’ebyuma. Tewali yali spec'd essaawa za operating correctly.
Kino kye tukola mu ngeri ey’enjawulo era lwaki kikulu bw’oba onoonya ebipande bya LCD ku mbeera y’obusuubuzi eyeetaaga okutambula.
Gye Tutuula mu Supply Chain
Tuli module-level integrator nga tusinziira mu Xiamen. Tetukola ndabirwamu ya TFT-eva mu layini z'okufulumya eza BOE, AUO, oba Innolux okusinziira ku spec yo kye yeetaaga. Kye tufuga buli kimu oluvannyuma lw’endabirwamu: dizayini y’ettaala y’emabega, okusengeka bboodi ya ddereeva, enkola ya FPC, okuddukanya ebbugumu, okugatta enclosure, n’enkolagana n’enkola yo ey’okuddukanya ebirimu.
Positioning eno erina tradeoffs z'osaanidde okutegeera nga tetunnaba kwogera.
Tusobola okukwataganya ebifulumizibwa mu kitangaala eky’emabega n’embeera yo ey’okussaako, okutegeka ebipande bya ddereeva ku nsengeka ya siginiini okufulumya kw’omuzannyi wo ow’emikutu, n’okukola dizayini y’okugatta kw’ebyuma okukwatagana n’enkola yo ey’okunyweza. Tetusobola kutondawo sayizi za panel za novel oba pixel geometries-that's tier-one fabricator territory nga NRE etandikira ku $100K+ ne minimum volumes ezikola amakulu ku programs ennene ennyo zokka.
Ku pulojekiti ezisinga ez'ebipande eby'amaguzi-shelf-edge eraga, end-cap screens, checkout lane signage, window-etunudde mu kwolesebwa kw'okutumbula-semi-omulimu gwa modulo ogw'ennono gubikka ku ekyo ky'olina ddala okwetaaga. Singa pulojekiti yo yeetaaga ekintu kye tutasobola kukola ku mutendera gwa module, ekyo tujja kukugamba upfront era tukusonga eri aba fabricators abasobola.
Emboozi y'Ensimbi
Oba ogeraageranya eby’okulondako. Laba engeri emiwendo gye gikola mu butuufu ku mutendera gwaffe ogw’okugaba ebintu.
Off-the{1}}shelf commercial displays okuva mu Samsung, LG, oba BOE retail product lines zitwala specs ezitakyukakyuka n'emiwendo egy'enkalakkalira. Ekipande ky’ebyobusuubuzi ekya yinsi 43-kidduka doola nga 1,200; Yuniti za yinsi 55 ezibalirirwa ebweru zitandikira ku doola 6,000. Ofuna ebyo katalogu by’ekuwa.
Omulimu gwa modulo ogwa custom gwongera ku nsimbi za yinginiya ezisookerwako-giyite $4,000 okutuuka ku $8,000 ku ya bulijjobar-ekika oba okulaga okugoloddwapulojekiti nga bakozesa ebifo eby’endabirwamu ebiriwo. Ekyo kikwata ku dizayini ya bboodi ya ddereeva, spec y’ettaala y’emabega, CAD ey’ebyuma, ne sampuli za prototype. Oluvannyuma lwa NRE, emiwendo gya buli-yuniti gisinziira ku bungi n’obuzibu, naye ku biragiro ebisukka mu bitundu 2,000-3,000 tutera okuyingira wansi w’ebintu bya katalogu ebyenkanankana ne 15-20%.
Okubala: bw'oba oteeka mu nkola yuniti 500, custom osanga tekola makulu-NRE ekendeeza ku $8-16 buli yuniti waggulu w'omuwendo gw'ekitundu. Bw’oba oteeka yuniti 5,000 mu lujegere lw’ekitundu, NRE efuuka amaloboozi era ofuna ebikozesebwa ebizimbibwa okusinziira ku mbeera yo mu kifo ky’okugituukanya.
Tujja kuddukanya ennamba entuufu eza pulojekiti yo. Tuweereze sayizi zo z'ogenderera, ebyetaago by'okumasamasa, n'okuteebereza eddoboozi-tukyusa ballpark costing mu ssaawa 48.
Ekituufu Ekigenda Ekikyamu mu Retail LCD Deployments
Mode ssatu ez’okulemererwa ziraga enfunda n’enfunda nga tuleeteddwa okutereeza pulojekiti y’omuntu omulala.
Ekkomo ku bbugumu lyasukka.
Eddirisa-ebitunudde mu kussaako bifuna ebbugumu. Omugugu gw’enjuba gwongera diguli 15-20 ku bbugumu erya panel ery’omunda okusukka ambient. Okwolesebwa okw’ebyobusuubuzi okuweebwa omutindo gwa 40℃max internal temp kukuba ekkomo eryo ku musana ogw’emisana. Mode y'okulemererwa ye capacitor degradation-tofuna kufa kwa mangu, ofuna okufiirwa okwaka mpolampola n'okukyuka kwa langi mu myezi 12-18 okutuusa nga screens zirabika nga zifuuse ekyeyoleka. Okutereeza kwe kukola speccing panels nga zirina thermal margins empanvu n’okugatta active oba passive cooling ku module design stage. Kino tukikoze ku bifo eby’amangu eby’okuvuga mu bifo eby’okulya mu Arizona ne Texas nga ambient plus solar ekuba diguli 60 munda bulijjo.
Duty cycle obutakwatagana.
Ebipande by’abakozesa n’ebimu ku bitundu by’obusuubuzi eby’omutindo ogwa wansi-bikoleddwa okukola essaawa 4-6 buli lunaku. Zidduse essaawa 16 era LED backlight phosphor degradation yanguwa nnyo-obulamu obugereddwa obw’essaawa 50,000 bufuuka essaawa 15,000 entuufu. Twalina aomusuubuzi w’emmeremu Southeast zzaawo shelf-edge yaabwe yonna oluvannyuma lw'emyezi 14 kubanga tewali yali akakasizza backlight spec okusinziira ku ssaawa zennyini ez'okukola. Okukyusa ssente za ssente nnyingi okusinga okukikola obulungi mu kusooka.
Obutakwatagana mu nkolagana (interface).
Media player yo efulumya HDMI. Oba LVDS. Oba kiosk controller yo yeetaaga GPIO triggering ku synchronized multi-screen content. Standard commercial displays zitwala ensengeka y’okuyingiza eyeetongodde. Bwe kitakwatagana na nsengeka ya nkola yo, oba oyongerako abakyusa, adapta, n'omulimu gw'okugatta ogwandibadde gwewalibwa nga olambika bulungi enkolagana ku ddaala lya modulo.
Bino tetubiwandiika nga ebirimu ebisomesa. Tuziwandiika kubanga singa emu ku modes zino ez'okulemererwa ekwatagana n'embeera yo ey'okuteeka mu nkola, weetaaga emboozi n'omuntu asobola spec okwetoloola.
Bye Twetaaga Okuva Ggwe Okujuliza
Emboozi esooka ekola obulungi yeetaaga okumanya ebimu ku ludda lwo:
- Target screen sizes n'emigerageranyo gy'ebifaananyi. Bw’oba okyusa ebipande ebiriwo, ennamba z’emmotoka ziyamba. Bw’oba okola dizayini y’ebintu ebipya ebiteekebwamu, ebiziyiza ebipimo n’enkola y’okussaako.
- Embeera y’okussaako. Embeera y’obudde efugirwa munda, munda naye nga eddirisa-eriraanye, semi-ebweru, ebweru omujjuvu. Kino kivuga brightness spec, thermal design, n'ebyetaago by'okugereka IP.
- Ssaawa z'okukola. 8/5, 12/7, 24/7. Kino kikosa okulonda ettaala y’emabega n’obulamu bw’obuweereza obusuubirwa.
- Volume n’enteekateeka y’ebiseera. Yuniti mmeka, ku nteekateeka ki ey’okuteeka mu nkola, ddi okufulumya kwe kwetaaga okutandika.
- Ebyetaago by’okugatta. Media player oba CMS yo kye ki? Enkola ya siginiini ki? Waliwo ebyetaago byonna eby'enkolagana y'okufuga?
Tetwetaaga kuddamu kwa nkomerero ku buli kimu-naye gy'okoma okutubuulira, okuddamu kwaffe okusooka gye kukoma okuba okw'omugaso.
Lwaki Tomala Kugula Samsung oba LG Commercial Displays
Ku pulojekiti ezimu, olina. Ebintu ebiraga eby’obusuubuzi eby’ekika (brand commercial displays) bijja n’ebiragiro bya ggaranti ebiteereddwawo, emikutu gy’empeereza egimanyiddwa, n’empapula z’ebintu (spec sheets) z’osobola okwesiga. Singa okuteekebwa mu nkola kwo kukwatagana ne sayizi za katalogu zaabwe, embeera yo eri mu bipimo byabwe ebigereddwa, era ng’olina embalirira, tewali kikyamu kugenda mu kkubo eryo.
Tukola amakulu nga ebintu bya katalogu tebituukagana na byetaago byo-nga weetaaga a28-yinsioba 37-inch bar-type ekitaliiwo mu katalogu za brand, nga ebiziyiza byo eby'okussaako byetaaga ebipimo by'enclosure ebitongole, nga ekyetaagisa kyo eky'okumasamasa kitudde wakati w'ebyo standard indoor and outdoor units bye biwa, oba nga volume efuula custom economics okukola mu bulungi bwo.
Tetuvuganya na Samsung ku straight 55{2}}inch commercial display. Tuvuganya ku pulojekiti nga off-the-shelf tekola bulungi era omuguzi akimanyi.
Omutendera oguddako
Bw’oba weetegereza enkola za LCD ez’enjawulo ku bipande by’amaduuka era ng’oyagala okutegeera oba pulojekiti yo etuukana n’obusobozi bwaffe, tuweereze ebyetaago byo. Tujja kuddamu n'okwekenneenya okw'amazima-oba kikola amakulu okukola naffe, oba ebintu eby'omutindo byandikuweereza bulungi, oba oba weetaaga obusobozi bwe tutalina.
Tubadde tukola module-level integration for retail and commercial display applications okuva mu 2019. Obusobozi bwaffe obw'okufulumya butambula yuniti 500 ku 40,000 buli mwaka buli SKU. Obudde bw’okukulembera sampuli buli wiiki 8-10 okuva ku dizayini ekkiriziddwa; okufulumya kwongera wiiki 4-6 okusinziira ku bungi.
