Embodiment 1
[0024] Please combine Figure 1 to Figure 5 As shown, it discloses a super macro brightness enhancement film. The above-mentioned ultra-macro-pitch brightness enhancement film and light source gain module are installed in the light source light-emitting module in the CIS, so as to realize the relatively scattered incident light emitted by the light source 20.
[0025] The ultra-macro-pitch brightness enhancement film is based on the principle of a prism. When the light enters from a dense medium to a sparse medium (such as water into air), when the angle is greater than the critical angle (the refractive index of the material determines the critical angle), total reflection will occur, causing the light to scatter. The light from the ultra-macro-pitch brightness enhancement film 10 achieves lateral concentration, thereby increasing the forward brightness, solving the problem of wasted light source, increasing the lateral uniformity, and significantly reducing the continuous wa...
Embodiment 2
[0029] The main difference between this embodiment and the super macro brightness enhancement film disclosed in Embodiment 1 is that, in this embodiment, the refractive index of the super macro brightness enhancement film 10 is 1.49, and the super macro brightness enhancement film 10 Gloss Film 10 monolithic acrylonitrile-butadiene-styrene copolymer. The haze of Super Macro Brightness Enhancement Film 10 is 90%. A super macro-pitch brightness enhancement film disclosed in this application is most preferably made of the acrylonitrile-butadiene-styrene copolymer (ie ABS).
[0030] ginseng Figure 1 ~ Figure 3 As shown, through the super macro brightness enhancement film pair disclosed by this institute figure 1 It can be seen that the images to be scanned are scanned by CIS without and with the ultra-macro-pitch brightness enhancement film disclosed by the present invention, respectively. figure 2 The outline of the bamboo shown is not clear and the brightness is obviously d...
Embodiment 3
[0033] The main difference between this embodiment and the super macro brightness enhancement film disclosed in Embodiment 1 or Embodiment 2 is that in this embodiment, the refractive index of the super macro brightness enhancement film 10 is 1.47, and the Super macro brightness enhancement film 10 integral acrylonitrile - butadiene - styrene copolymer. The haze of Super Macro Brightness Enhancement Film 10 is 85%. For the technical features that are the same in this implementation as in Embodiment 1 or Embodiment 2, please refer to Embodiment 1, and details will not be repeated here.
