Applications such as demand, and the surface pre-earthly 402 also has the advantage of flattening; of course, we can also use a non-axial structure tree with = phase phase modulation to achieve this purpose, and the non-axisymmetric, The structural effects of the 7L pieces are as follows. FIG. 2A is a sound recording W of a non-minus structural element with a diffractive optical phase. When the dimension diameter of the non-axisymmetric diffractive element 10 is 5 ^ 10 times the wavelength of incident light, it can make The incident light 1 is diffracted to divide the incident light 丨 into a focal point ⑴ 200527719 11 ^ 12 5 13 as the g Γ point.

It can also be applied to the backlight module towels of large-size LCD screens to reduce the uniformity of light when the point light source is expanded to the surface light source. Qing's degree of heterogeneity is more suitable for mass production; however, the above is only a rudimentary embodiment of the present invention. When it is related to the scope of the present invention, it is easy to associate with 'such as: the plane optical modulation unit is The concentric and ring structure is changed into a concentric circle structure, or other thief materials are used. Those skilled in this field will be able to implement the job after they understand the spirit of the present invention. Equivalent changes and modifications will still lose the essence of the invention and also depart from the spirit and scope of the invention, so they should be regarded as the further implementation of the invention. As mentioned above, the invention is based on conventional technology There is no related technical disclosure in the field, which is already new; the technology of the present invention can surely solve the problems in this field, and the principle of the method is not completed based on the conventional knowledge, and its efficacy has been detailed It is really progressive and has already met the requirements of the invention patent stipulated in the Patent Law.
