Abstract: A compensation structure of liquid crystal panels is disclosed. The compensation structure includes a liquid crystal panel and a first polarizing film and a second polarizing film arranged on two opposite surfaces of the liquid crystal panel. The liquid crystal panel comprises a liquid crystal layer having a plurality of liquid crystal molecules. An anisotropy reflective index of the liquid crystal layer is Δn, the thickness of the liquid crystal layer is d, and a pretilt angle of the liquid crystal molecules is θ. The first compensation film is a biaxial compensation film, and an in-plane retardation value and a thickness retardation value of the first compensation film are respectively Ro1 and Rth1. The second compensation film is the single-axial compensation film, and the thickness retardation value of the second compensation film is Rth2, wherein: 324.3 nm≦Δn×d≦342.7 nm; 85°≦θ

Abstract: An apparatus and a system for measuring flicker of a display panel are disclosed. The apparatus comprises a light guide tube, a measuring probe for flicker measurement, and an optical device for diverging fight. The light guide tube comprises an opening at a first end and an opening at a second end. The trumpet-shaped light guide tube gradually enlarges from the opening at the second end to the opening at the first end. The opening at the first end is used fir receiving light emitting from the periphery regions and the center region of the display. Light entering into the light guide tube through the opening at the first end emerges from the opening at the second end and is transmitted to the measuring probe through the optical device having a diverging effect. The more overall flicker information is acquired to improve the accuracy of measurement.
