Compensation system and liquid crystal display apparatus for liquid crystal panel |
摘要 |
The present invention discloses a compensation system and a liquid crystal display apparatus used for a liquid crystal panel. The compensation system comprises a first biaxial retardation film and a second biaxial retardation film respectively disposed on either side of the liquid crystal panel. An in-plane retardation value of the first biaxial retardation film at a wavelength of 550 nm is Ro1. An out-of-plane retardation value in a thickness direction is Rth1. An in-plane retardation value of the second biaxial retardation film at the wavelength of 550 nm is Ro2. An out-of-plane retardation value in a thickness direction is Rth2. Wherein: 30.8 nm≰Ro1≰91 nm; 70.4 nm≰Rth1≰208 nm; 21 nm≰Ro2≰93.8 nm; Y1≰Rth2≰Y2; Y1=0.00424817×Rth12−1.9854256×Rth1+277.7: Y2=−0.003333×Rth12−0.033459×Rth1+234.2. The present invention effectively reduces light leakage of the liquid crystal panel in dark mode by disposing the double-layered biaxial retardation films having reasonable retardation values. |
