s50, sequentially cutting and splitting the ITO glass substrate in the step S40, and pouring PNLC liquid into each area of the ITO glass substrate under the condition of irradiation of a special light source; after the PNLC liquid in the step S50 is cured, a photoelectric effect exists in an interval of-10 to 60 degrees, wherein the PNLC liquid meets the characteristics shown in the figure 1; the special light source in step S50 is a sodium yellow light source.
S60, sequentially carrying out sealing, UV curing, edging, cleaning and aging treatment on the glass substrate poured in the step S50 to obtain PNLC liquid crystal glass; wherein, the haze of the product obtained in the step S60 in the initial state is 0.1%, when the voltage is applied to 15V or more, the haze is higher than 60%, and the light transmittance is greater than 75%; the core thickness between the first ITO glass and the second ITO glass in step S60 is 4 μm, and controlling the core thickness in a specific range is very critical to reduce the initial haze; the temperature of aging in the step S60 is 70 ℃, the aging time is 60min, in the implementation process, the core thickness is large, the overall thickness of the PNLC liquid crystal glass is thick, the initial haze is high, the same core thickness is small, the initial haze is high, but the final haze is reduced, and when the PNLC liquid crystal glass is used, the final haze needs to be high, so as to achieve the atomization reminding effect, so that the core thickness is controlled in the region of 3-10 μm, so that the finally formed PNLC liquid crystal can ensure that the initial haze is low, the transparency is high, the normal use is not affected, the haze after atomization is high, and the atomization reminding effect can be obviously played.
And S70, carrying out FOG binding on the qualified PNLC glass in the step S60, and then sequentially carrying out film pasting, bubble baking, adhesive pasting and UV curing to obtain the PNLC lens. The film pasting process in the step S70 comprises the steps of sequentially pasting a blue light protection film and an AF film on one side, far away from the second ITO glass, of the first ITO glass; according to the invention, in order to better protect the impact resistance and the falling performance of the display screen made of the PNLC glass material on the spectacle lens, the design of the two-side film-coated explosion-proof film is added, and the falling effect of the display screen is better protected.
The specific design is that the front surface is additionally provided with a blue light prevention film to achieve a blue light protection effect, the bottom surface is additionally provided with an AR film to increase the light transmittance of the lens, and the outermost layers of the front surface and the back surface are further subjected to AF fingerprint prevention treatment.
The AF film is a high-transmittance fingerprint-proof AF film, is called AF film for short, solves the problem that the prior frosted film and the high-transmittance film cannot simultaneously prevent fingerprints, oil and dust, has very high light transmittance and does not have the fog face feeling of the frosted film. The AF (Anti-fingerprint) Chinese is Anti-fingerprint, and the common AF material has two forms, one is liquid AF Anti-fingerprint liquid medicine, the other is AF Anti-fingerprint target pill, corresponding to two different production methods, the Anti-fingerprint liquid medicine is suitable for preparing AF by a spraying method, and the AF Anti-fingerprint target pill is suitable for preparing AF by a vacuum evaporation coating method.
The AF antifouling fingerprint film can reduce the surface tension of the PNLC glass layer, and the contact area of dust and the glass surface is reduced by 90%, so that the PNLC glass layer has strong hydrophobic, oil stain resistant and fingerprint resistant capabilities. So that the PNLC glass layer can keep bright and clean for a long time.
The blue light protection film, i.e. the blue light protection layer, is a product developed on the basis of reducing the damage of blue light to people. Compared with the newly-developed screen protective film in the market, the blue light-proof protective film has the functions of explosion prevention, fingerprint elimination, scratch prevention, sterilization and the like, and has the most characteristic function of blue light blocking. Through absorbing and converting the blue light that light emitting sources such as cell-phone, computer, TV, LED lamp distribute out, prevent that the blue light protection film can alleviate the stimulation of blue light to eyes greatly, control myopia deepens. The blue light protective film can prevent myopia, and also can prevent the generation of skin stains, chloasma and other problems caused by skin dryness due to ultraviolet reflection through absorbing and converting ultraviolet rays.
ARAF rupture membranes are a type of rupture membrane. AR (anti-reflection), chinese is anti (anti) reflection. Mainly can reduce the reflected light on the surface of the PNLC glass layer, thereby enhancing the light transmission amount of the glass (screen) and reducing or eliminating the stray light of the system. The material with high and low refractive index can be used for cross-stacked plating, and vacuum evaporation plating or magnetron sputtering plating can also be adopted.
When light is emitted to the light-tight substance from the light-sparse substance, half-wave loss of reflected light occurs, after the PNLC glass layer is coated with the AR film, the optical path difference of the reflected light on the surface is just half wavelength different from that of the reflected light on the front surface of the film, and the reflected light on the front surface and the rear surface of the film are offset, namely, the energy of the projected light is increased, and the effects of reflection and reflection increasing are achieved. And can let two faces of glass reduce reflection effect simultaneously through coating film simultaneously at PNLC two sides, can greatly alleviate eye fatigue to slow down the eyesight and descend. The ARAF rupture membrane used in the invention integrates the above effects and the explosion-proof effect.
