Ihe fọrọ nke nta ka ọ bụrụ ihe nkiri ngwa anya niile ka a na-eji na sistemụ ngosipụta ngosipụta kristal mmiri. Igwe anya ihe ngosi LCD na-ahụkarị nwere isi iyi ọkụ (oriọna halide metal ma ọ bụ oriọna mercury dị elu), sistemu ngwa anya ọkụ (gụnyere sistemu ọkụ na sistemu ntụgharị polarization), nkewa agba na sistemụ ngwa nchikota agba, ihuenyo LCD, na usoro nyocha anya.
1, AR+HR
Dị ka mmiri mmiri kristal projection usoro maka elu ngwa anya arụmọrụ chọrọ, na-eji elu-arụmọrụ Mbelata nke reflective film na elu reflective film, nwere ike ime ka usoro ngwa anya ike site ọ bụla ngwa anya interface na na refractive ọnwụ na-ebelata, na n'otu oge ahụ nwere ike jirichaa ókè nke suppression nke kpafuo ìhè, na-ewepụ "mmanya image" na melite "mmanya image".
2. Infrared, ultraviolet cutoff filter
A na-ejikarị usoro ntule kristal mmiri na-eme ka ọ dịkwuo mma nke ìhè ọkụ dị elu, nke na-ebunye ọnụ ọgụgụ dị ukwuu nke ultraviolet na ìhè infrared na ụdịdị ahụ. Ojiji nke infrared, ultraviolet ịkpụ ihe nzacha nwere ike wepu ọkụ ultraviolet na-emerụ ahụ na okpomọkụ infrared na usoro ahụ, iji gbochie ịka nká kristal mmiri, meziwanye ndụ ọrụ nke usoro ahụ.
3, ihe nkiri ntụgharị ọkụ polarized
Kristal mmiri na-achọ ka e jiri ya mee ihe na-acha ọkụ ọkụ, nke na-achọ mgbanwe nke ìhè na-esi n'ìhè ahụ pụta na ìhè polarized. Polarizing Beamsplitters (PBS) nke a kwadebere site na iji ihe nkiri anya nwere ike ịtụgharị ìhè ka ọ bụrụ ìhè polarịized.
4. Nkewa agba na ihe nkiri ngwa anya na-ejikọta agba
N'ime sistemụ ngosipụta amụma kristal mmiri, nkewa agba na njikọ ụcha na-abụkarị ihe nkiri anya. Iji melite àgwà nke usoro, n'ozuzu chọrọ nke mmepụta nke agba nkewa film kwesịrị ọ bụghị nanị na a elu wavelength n'ọnọdu ziri ezi na iji hụ na agba nke elu àgwà, ma na-achọ spectral curve nke dichroic mirror na nkewa wavelength nwere a elu steepness e ji mara, na ịkpụ-apụ band nwere a miri ngafe ebipụ, nwere a dị elu nke ngafe mbepụ, na-ebufe n'ókè dị elu.
