Embodiment 1
[0089] Such as image 3 As shown, the present invention provides an optical composite film, the optical composite film comprising: a first layer of optical film and a second layer of optical film; the first layer of optical film is placed above the second layer of optical film, the two through The bonding layer 52 is bonded together; the first layer of optical film includes the microlens structure layer 51, and the first layer of substrate layer 50; the second layer of optical film includes the prism layer 61 in sequence, and the second layer of base layer Material layer 60, and back coating 62.
Embodiment 2-10
[0091] For the optical composite film provided in Example 1, the technical parameters are shown in Table 1.
[0092] The technical parameters of Embodiment 1-10 are shown in Table 1-1 and Table 1-2 below.
[0093] The technical parameters of the first layer of optical film of the optical composite film that table 1-1 embodiment 1-10 provides
[0094]
[0095] Note: The refractive index of the prism resin generally refers to the refractive index of the glue before curing, and the index that can be detected is also the refractive index before curing, so it can also be called the refractive index of the resin finger liquid.
[0096] The technical parameters of the second optical film and the bonding layer of the optical composite film provided in Table 1-2 Examples 1-10
