3. QLED
QLED, Quantum Dot Light Emitting Diode (Quantum Dot Light Emitting Diode), bụ teknụzụ na-enye ọkụ dabere na ntụpọ quantum. A na-etinye oyi akwa quantum dot n'etiti ụgbọ njem eletrọn na oghere na-ebufe organic ihe dị n'ígwé, na-etinyekwa ọkụ eletrik dị n'èzí iji bugharịa electrons na oghere. n'ime oghere ntụpọ quantum, mgbe ahụ, electrons na oghere na-ejikọta ọnụ iji na-amụnye ìhè. Ọdịdị nke QLED yiri nke OLED. Isi ihe dị iche bụ na ihe na-eme ka ọkụ nke QLED bụ ihe inorganic quantum dot, ebe OLED na-eji ihe ndị dị ndụ. QLED nwere njirimara nke ikuku ọkụ na-arụ ọrụ, nrụpụta ọkụ dị elu, ọsọ nzaghachi ngwa ngwa, ụdị dị iche iche na-agbanwe agbanwe, gamut agba agba, wdg. Ọ kwụsiri ike ma nwee ogologo ndụ karịa OLED. Enwere isi ụdị ngwa abụọ nke teknụzụ QLED. Otu bụ quantum dot backlight technology dabeere na fotoluminescence Njirimara nke quantum dots, ya bụ, na-agbakwunye quantum dots na azụ azụ nke LCD iji melite mmepụta agba na nchapụta; nke ọzọ bụ quantum dot backlight technology. Ngosipụta ihe ngosi diode ntụpọ quantum dot light-emitting diode dabere na njirimara electroluminescence nke quantum dots, ya bụ, ntụpọ quantum na-agbanye n'etiti electrodes iji na-ebunye ọkụ ozugbo, na-eme ka ọdịiche na akụkụ nlele. Ka ọ dị ugbu a, ihe ngosi QLED dabere na quantum dot backlight mode ejirila ọtụtụ ebe n'ahịa. Ihe a na-akpọ "TV quantum dot TV" dị n'ahịa bụ LCD TV nwere ihe nkiri quantum dot, na isi ha ka bụ teknụzụ LCD.
4. Obere LED
Obere LED bụ diode ọkụ na-emitting sub-millimeter (Obere Light Emitting Diode), nke bụ ngwaọrụ ikanam nwere nha mgbawa n'etiti 50-200μm. Ọ bụ n'ihi nrụzi ọzọ nke obere-pitch LED.
Ngwa nke Mini LED na-ekewa n'ime iji obere obere ọkụ ọkụ dị ka ihe ngwọta azụ azụ LCD na ihe na-enye ọkụ nke na-eji ọkụ ọkụ RGB atọ, ya bụ, ngwọta azụ azụ na ngwọta ngosi. Obere ọkụ azụ nke LED bụ ntụziaka dị mkpa maka nkwalite teknụzụ LCD, nke nwere ike melite ìhè LCD na ọdịiche gbara ọchịchịrị na ngosipụta dị ike, si otú ahụ na-eme ka nghọta ahụ dịkwuo elu. Obere LED kpọmkwem ngosi nwere ike ịbụ spliced n'enweghị nkebi nke ọ bụla size, eme ka ojiji ndapụta nke nnukwu-size ihuenyo ngosi. Ọ nwekwara ike imeziwanye arụmọrụ ngosi dị ka ọdịiche, omimi agba, na nkọwa agba.
5. Micro LED
Micro LED, Micro Light Emitting Diode, makwaara dị ka mLED ma ọ bụ μLED, bụ teknụzụ ngosi LED dabere na ọkwa micron. Ọ na-ebelata ibe ọkụ LED na ọkwa micron ma jikọta ọtụtụ nde ha na nkeji ngosi. Igwe ọkụ LED na-achọpụta ihe ngosi onyonyo site na ijikwa mgbanyụ na gbanyụọ nke mgbawa LED ọ bụla. Enwere ike ikwu Micro LED ka ọ jikọta uru niile nke LCD na OLED. Ọ nwere uru dị ịrịba ama dị ka mkpebi dị elu, obere ike oriri, nchapụta dị elu, ọdịiche dị elu, saturation agba dị elu, nzaghachi ngwa ngwa, ọkpụrụkpụ dị mkpa, na ogologo ndụ. Otú ọ dị, ọ na-eche ihu ugbu a Usoro mmepụta ihe siri ike na ọnụ ahịa mmepụta dị elu.
N'ime obere oge, ahịa Micro LED lekwasịrị anya na ngosipụta ultra-obere. Na ọkara ruo ogologo oge, Micro LED nwere ọtụtụ ngwa dị iche iche, na-agbatị ngwaọrụ wearable, nnukwu ihuenyo ime ụlọ, ihe ngosi isi (HMD), ihe ngosi isi elu (HUD), ọkụ ọdụ ụgbọ ala, mgbasa ozi ngwa anya ikuku Li-Fi, na AR / VR, ndị na-emepụta ihe na ubi ndị ọzọ.
6. Micro OLED
Micro OLED, nke a makwaara dị ka OLED nke dabeere na silicon, bụ ngwaọrụ ngosipụta micro dabere na teknụzụ OLED. Ọ na-eji otu usoro silicon kristal ma nwee njirimara nke ìhè onwe ya, njupụta pixel dị elu, obere nha, obere ike oriri, nnukwu ọdịiche na ọsọ nzaghachi ngwa ngwa.
Uru nke Micro OLED na-esite na njikọ chiri anya nke teknụzụ CMOS na teknụzụ OLED, yana ogo dị elu nke ntinye nke ihe semiconductor inorganic na ihe semiconductor organic. N'adịghị ka ihuenyo OLED ọdịnala nke na-eji ihe iko iko, Micro OLEDs na-eji mkpụrụ osisi silicon monocrystalline, na sekit ọkwọ ụgbọ ala na-ejikọta ya na mkpụrụ, na-ebelata oke ihuenyo ahụ. Na n'ihi na ọ na-eji teknụzụ semiconductor, oghere pixel ya nwere ike ịdị n'usoro nke ọtụtụ microns, si otú ahụ na-abawanye njupụta pixel n'ozuzu ya. Enwere ike ịghọta ya dị ka iji teknụzụ nrụpụta mgbawa wuo ihuenyo.
Micro OLED na OLED yiri ụkpụrụ. Nnukwu ihe dị iche n'etiti ha bụ "Micro". Micro OLED pụtara pikselụ pere mpe ma dabara adaba maka ojiji na obere nha, arụmọrụ dị elu, ngwaọrụ ngosipụta dị elu dị ka ihe nlebanya n'isi (HMD) na ihe nlele eletrọnịkị (EVF).
