Problems solved by technology

The device is provided with multiple functional layers on the surface of the substrate layer. Although it can achieve brightness enhancement, the light-gathering brightness enhancement effect is average, and it still looks dark.
[0004] Another example is a brightness enhancement film disclosed in the US patent document US0274876. Since the brightness enhancement film is a variety of optical structures with substrates bonded through an adhesive layer, the overall film layer is thicker and the cost is higher. The characteristics of simplification and compounding of diaphragm in the future

Abstract

The invention discloses an optical film. The optical film comprises a first optical film structure layer with a support layer and at least one second optical film structure layer without a support layer, wherein the first optical film structure layer and the second optical film structure layer are mutually fixed; and an air structure is left between the first optical film structure layer and the second optical film structural layer. Through setting the air structure, the existence of the air structure enables the light collecting effect to be effectively enhanced and enables the brightness tobe effectively improved; and compared with the optical films with two support layers on the market, the base materials of the optical film are decreased, so that the absorption and reflection, for thelight, of the base materials are decreased, the transmitted light is increased, and the optical gain is further improved.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to an optical film. Background technique [0002] Brightness enhancing films are important components in liquid crystal displays (LCDs). The brightness-enhancing film is used to make the light emitted more concentratedly and concentrated in the range of the viewing angle of the user, so as to improve the brightness of the LCD. [0003] As another example, Chinese patent document CN105204101A discloses a brightness enhancement film, the brightness enhancement film includes a support layer and a functional layer arranged on the surface of the support layer, and it is characterized in that the functional layer includes a plurality of sub-functional layers, Each of the sub-functional layers has a three-dimensional pattern, and the refractive index of each of the sub-functional layers increases along a direction away from the supporting layer. The device is provided with a plurality of f...
