TFT: Mkpa ihe nkiri transistor

LCD: Ngosipụta kristal Liquid

TFT LCD nwere ihe iko abụọ nwere akwa mmiri kristal sandwiched n'etiti, otu n'ime ha nwere TFT na nke ọzọ nwere nzacha agba RGB. TFT LCD na-arụ ọrụ site na iji transistor ihe nkiri dị mkpa iji jikwaa ngosipụta nke pixel ọ bụla na ihuenyo. Ihe mejupụtara pixel ọ bụla bụ uhie, akwụkwọ ndụ akwụkwọ ndụ, na acha anụnụ anụnụ, nke ọ bụla nwere TFT nke ya. TFT ndị a na-eme dị ka mgba ọkụ, na-achịkwa ole voltaji ezigara na sub-pixel ọ bụla.

Igwe iko abụọ: TFT LCD nwere mkpụrụ iko abụọ nwere akwa akwa kristal mmiri nke sandwiched n'etiti ha. Mkpụrụ abụọ a bụ isi ihe ngosi nke ihe ngosi.

Ihe nkiri transistor dị mkpa (TFT): N'ịbụ nke dị na mpempe iko, pikselụ ọ bụla nwere transistor ihe nkiri dị mkpa kwekọrọ. Ndị transistors ndị a na-arụ ọrụ dị ka mgba ọkụ na-achịkwa voltaji nke pixel ọ bụla na oyi akwa kristal mmiri.

Okpokoro kristal Liquid: Dị n'etiti mkpụrụ iko abụọ, mkpụrụ ndụ kristal mmiri na-atụgharị n'okpuru ọrụ eletriki, nke na-achịkwa ogo ọkụ na-agafe.

Nzacha agba: Ọ dị na mkpụrụ iko ọzọ, a na-ekewa ya ka ọ bụrụ redpixels na-acha uhie uhie, akwụkwọ ndụ akwụkwọ ndụ na acha anụnụ anụnụ. Subpixels ndị a kwekọrọ n'otu-na-otu na transistor dị na matriks TFT wee chọpụta agba nke ngosi ahụ.

Ìhè azụ: Ebe ọ bụ na kristal mmiri n'onwe ya anaghị ewepụta ìhè, TFT LCD chọrọ isi iyi ọkụ azụ iji mee ka oyi akwa kristal mmiri pụta ìhè. Igwe ọkụ azụ azụ ndị a na-ahụkarị bụ LED na Cold Cathode Fluorescent Lamps (CCFLs)

Polarizers: Dị n'akụkụ ime na mpụta nke mkpụrụ iko abụọ, ha na-achịkwa ụzọ ọkụ si abanye wee pụta na oyi akwa kristal mmiri.

Bọọdụ na IC ọkwọ ụgbọ ala: A na-eji njikwa transistor dị na matrix TFT, yana idozi voltaji nke oyi akwa kristal mmiri iji chịkwaa ọdịnaya egosipụtara na ihuenyo ahụ.
