LCD (Liquid Crystal Display) panels no dwumadie ne ne dwumadie nya nkɔsoɔ kɛseɛ denam nneɛma ahodoɔ a ɛho hia ne mfiridwuma a ɛboa display system no so. Saa nneɛma yi ho hia ma sɛnkyerɛnne dwumadie, component connectivity, ne hwɛ a wɔhwɛ sɛ ɔyɛkyerɛ no nyinaa ahotosoɔ ne dwumadie. Nneɛma a ɛho hia ne mfiridwuma ho nimdeɛ yi ho nsɛm a wɔaka abom ni:
- TFT LCD layer .: Eyi ne ade a wɔde kyerɛ no mfinimfini a wɔde nsu ahwehwɛ molecule ahorow ahyɛ ahwehwɛ mprɛte abien ntam. Saa molecule ahorow yi sesa wɔn kwankyerɛ wɔ anyinam ahoɔden ho mmuaema mu, na ɛhwɛ sɛnea hann no fa so no so.
- Nneɛma a ɛyɛ tratraa-Film transistors (TFT) .: Saa transistors yi si ahwehwɛ mprɛte no biako so na ɛyɛ adwuma sɛ ankorankoro switch ahorow ma pixel biara, na ɛma wotumi di ɔyɛkyerɛ no kɔla ne ne hyerɛn so pɛpɛɛpɛ wɔ piksel beae biara.
- Kɔla a wɔde yiyi nneɛma mu .: Wɔde eyinom ahyɛ ɔyɛkyerɛ no mu na wɔde yɛ kɔla ahorow denam akyi kanea no a wɔde yiyi mu ma ɛyɛ kɔla kɔkɔɔ, ahabammono, ne bruu no so. Pixel biara taa wɔ sub-pixel abiɛsa a ɛwɔ saa filters yi a wɔde bɛbɔ-kɔla spectrum a edi mũ no.
- Polarizers .: Polarizing filters abien wɔ hɔ, biako wɔ anim na biako wɔ liquid crystal layer no akyi, a ɛhwɛ hann a ɛkɔ mu ne nea efi mu ba no kwan so. Eyi hwɛ hu sɛ hann a ɛne nsu ahwehwɛ no kwankyerɛ nkutoo na ɛwɔ hɔ no betumi afa mu.
- Akyi kanea (BLU) .: Sɛnea TFT LCD ahorow no mma hann no, akyi kanea ho hia na ama hann aba ɔyɛkyerɛ no mu. Wɔtaa de LED akyi kanea di dwuma ma ɛyɛ adwuma yiye na ɛhyerɛn.
- Ahwehwɛ a ɛwɔ ase .: Eyinom ma structure fapem ma display no, gyina nsu crystal layer, TFTs, ne color filters. Wɔsan nso yɛ akwan a wɔfa so de anyinam ahoɔden nsɛnkyerɛnne kɔ TFT ne nsu ahwehwɛ mu.
- Driver ICS .: Saa integrated circuits yi na ɛyɛ asɛdeɛ sɛ ɛhwɛ TFTs so, kyerɛ input signals ase, na ɛhwɛ display no dwumadie nyinaa so, a nsakraeɛ a ɛwɔ hyerɛn, contrast, ne refresh rate ka ho.
- Nsɛm a wɔatintim a ɛyɛ mmerɛw (FPC) anaasɛ ribbon connectors .: Saa nneɛma yi de ɔyɛkyerɛ no bata afiri no nkae ho, na ɛde control signals ne power kɔ display no so.
Sɛ wɔka ne nyinaa bom a, saa nneɛma yi ma TFT LCD ahorow no tumi yɛ mfonini ahorow a ɛyɛ nnam na ɛyɛ hyew a ɛwɔ pixel biara so tumi pɛpɛɛpɛ, na ɛma ɛyɛ nea wɔpɛ ma nneɛma ahorow pii a wɔde di dwuma, a smartphone, tablɛt, mfiri a wɔde hwɛ nneɛma so, ne TV ka ho.
