Optical composite film and display panel
ActiveCN109085718AThe overall thickness is thinSolve the big screen role bias problemNon-linear opticsOptical elementsPrismRefractive index
The invention relates to an optical composite film and a display panel. The optical composite film comprises a reflection grating film layer, a single optical axis optical film layer, and a base layer. The single optical axis optical film layer comprises a plate part and a plurality of refraction parts. The plate part is laminated on the reflection grating film layer. The plurality of refraction parts are formed on one side of the plate part which is far away from the reflection grating film layer, and are arc surface columns or quadrangular prisms. The base layer is laminated on one side of the plate part near the refraction parts. The plurality of refraction parts are stored in the base layer. The refractive index of the base layer is smaller than the anomalous light refractive index ofthe single optical axis optical film layer. According to the optical composite film and a display panel, the large-viewing-angle color shift of the display panel can be improved, and the thickness ofthe display panel can also be reduced.
