Okwu Mmalite ka LTPS?

Obere okpomọkụ Poly-silicon (LTPS) bụ ụlọ ọrụ teknụzụ dị na North America na Japan iji belata ike ike ngosipụta PC ngosi , Teknụzụ mepụtara iji mee ka Note-PC pụta ìhè ma dị mfe, Gburugburu etiti 1990s, teknụzụ a malitere ịbanye na ikpe ikpe。 Ọgbọ ọhụụ nke OLED na-enwupụta ọkụ ọkụ OLED sitere na LTPS abanyekwara na ọkwa bara uru na 1998 , Ihe kachasị mma ya bụ nke dị ezigbo mkpa, ịdị arọ dị ala, obere ike oriri。 Nwere ike ịnye agba chara acha ma dokwuo anya. foto。

Obere okpomọkụ polysilicon

 A na-ekewa TFT LCD n'ime polysilicon (Poly-Si TFT) na amorphous silicon (a-Si TFT), Ihe dị iche n'etiti ụgha abụọ ahụ na njirimara nke transistor。A na-ahazi usoro ihe omimi nke polysilicon nke ọma ma na-eduzi ya na ọka , Yabụ, ọnụọgụ elektrọn bụ ọsọ 200-300 karịa nke silicon amorphous na-adịghị mma; Ihe a na-akpọkarị TFT-LCD na-ezo aka na silicon amorphous, Teknụzụ Mature, Ọ bụ ngwaahịa ngwaahịa LCD。Polysilicon na-agụnye polysilicon dị elu (HTPS) na polysilicon dị ala (LTPS)。

 Ala okpomọkụ Poly-silicon (LTPS) mkpa film transistor mmiri mmiri crystal ngosipụta dị na nkwakọ usoro, Iji excimer laser dị ka a okpomọkụ iyi, Mgbe laser ìhè gafere projection usoro, Ga-emepụta a laser doo na edo ike nkesa, atule na a iko mkpụrụ na ihe amorphous sịlịkọn Ọdịdị, Mgbe amorphous sịlịkọn Ọdịdị iko mkpụrụ na-amịkọrọ ume nke excimer laser, Ga-agbanwe n'ime a polysilicon Ọdịdị, N'ihi na dum ọgwụgwọ usoro na-agwụ agwụ n'okpuru 600 ℃, Ya mere, n'ozuzu iko iko na ọdabara.

  LTPS-TFT LCD nwere uru nke mkpebi dị elu, nzaghachi ngwa ngwa, nchapụta dị elu, na oghere oghere dị elu。 Tụkwasị na nke a, ebe ọ bụ na usoro kristal silicon nke LTPS-TFT LCD dị n'usoro karịa nke-Si, Mee ọnụego elektrọn dịtụ elu karịa 100 ugboro, A na-emepụta okirikiri ịkwọ ụgbọ elu n'otu iko mkpụrụ osisi n'otu oge ahụ, rute ihe mgbaru ọsọ nke mwekota usoro, chekwaa ohere na ụgbọala IC ụgwọ。

  N'otu oge, ebe ọ bụ na a na-eme ka onye ọkwọ ụgbọ ala IC na-eme ihe na panel, Nwere ike belata isi ihe ndị dị na mpụga, Mee ka ntụkwasị obi dịkwuo mfe, mmezi dị mfe, belata oge usoro mkpokọta ma belata njirimara EMI, Nke a na-ebelata oge a haziri nke ngwa ngwa ma gbasaa imewe nnwere onwe.

  Teknụzụ kachasị elu nke LTPS-TFT LCD bụ iji nweta Sistem na Panel, Ọgbọ mbụ nke LTPS-TFT LCD na-eji eriri elegharị anya arụ ọrụ na arụmọrụ pixel transistors dị elu iji nweta mkpebi dị elu na nchapụta dị elu. O meela LTPS-TFT LCD na a-Si nwere nnukwu ndịiche.

  Ọgbọ nke abụọ nke LTPS-TFT LCD site na ọganihu nke teknụzụ sekit, Site na nyocha analog na interface dijitalụ, Belata ike oriri. Ugbo njem nke ọgbọ a nke LTPS-TFT LCD bụ oge 100 nke a-Si TFT, widthdị eriri elektrọnị bụ ihe dịka 4μm, Ejirila njirimara LTPS-TFT LCD.

  Ọgbọ nke atọ LTPS-TFT LCD zuru oke karịa na njikọta nke abụọ (LSI) karịa ọgbọ nke abụọ, Ebumnuche ya bụ: (1) Enweghị akụkụ dị n'akụkụ iji mee ka usoro ahụ dịkwuo nro ma dị njọ, Ọ nwere ike belata ọnụ ọgụgụ nke akụkụ na nzukọ mmadụ-oge; (2) Nhazi mgbaàmà dị mfe nwere ike belata ike oriri; (3) Ejiri ya na ebe nchekwa iji belata ike oriri.

  N'ihi na LTPS-TFT LCD mmiri mmiri kristal ngosi nwere uru nke elu mkpebi, elu agba saturation, na ala na-eri, High olileanya na-etinye na a ọhụrụ ife nke ngosipụta.With elu circuit mwekota e ji mara na ala na-eri uru, Ọ nwere ihe zuru uru na ntinye nke ogwe ngosi ihe ntà na nke ọkara. Mana p-Si TFT nwere nsogbu abụọ, Otu bụ na ọnọdụ na-apụ apụ (yabụ ugbu a) nke TFT buru oke ibu (Ioff = nuVdW / L); Nke abuo, o siri ike ịkwadebe ihe p-Si na-agagharị agagharị. na nnukwu mpaghara na ala okpomọkụ. Enwere ụfọdụ ihe isi ike na usoro.

  Ọ bụ teknụzụ ọgbọ ọhụụ ewepụtara sitere na TFT LCD.A rụpụtara ihuenyo LTPS site na ịgbakwunye usoro nhazi laser na ngwongwo amorphous amorphous (a-Si) TFT-LCD. Ọnụ ọgụgụ nke ihe ndị ahụ nwere ike ibelata 40%, Na njikọ akụkụ nwere ike belata site na 95%, Nnukwu belata ohere nke ọdịda ngwaahịa.

E nwere ụzọ atọ dị mkpa iji jikọta ndị ọkwọ ụgbọ ala p-Si dị ala:

1, ngwakọ mwekota nke ịgụ isiokwu na data ịmafe, The circuit na-ike ọnụ, The mgba ọkụ na nnofega aha na-ike na kọlụm circuit, Otutu okwu ọkwọ ụgbọala na amplifiers na-ejikọrọ na ewepụghị panel ngosi na ketara eketa;

2, All mbanye na sekit na sekit na-n'ụzọ zuru ezu ike na ngosipụta ihuenyo;

3 、 Draịvụ na njikwa na-ejikọ sekit na ihuenyo ngosi.
