Detailed Description
As shown in fig. 3 and 4, a 0-degree polarized liquid crystal sunglass lens includes a left-eye lens and a right-eye lens, wherein the left eyeglass and the right eyeglass both comprise a front polaroid 1, a front ITO glass substrate or flexible film 2, a front ITO electrode 3, a front PI directional film 6, a box support sheet 7, a rear PI directional film 8, a COM electrode 0, a rear ITO glass substrate or flexible film 10 and a rear polaroid 11 in sequence from the front side to the rear side, a conductive adhesive 13, a sealing glue 4 and a rubber frame glass support sheet 5 are arranged between one ends of the front ITO glass substrate or the flexible film 2 and the rear ITO glass substrate or the flexible film 10, a sealing glue 12 is arranged between the other ends, the visual direction of the left spectacle lens is designed to be 7 to 8 points in right rotation, the visual direction of the right spectacle lens is designed to be 4 to 5 points in left rotation, the diameter of the box support sheet 7 is 3 to 4 microns, and the front polarizer 1 and the rear polarizer 11 are high-transmittance polarizers or EWV series polarizers;
when the front polarizer 1 and the rear polarizer 11 are high-transmittance polarizers, the transmittance is required to be more than or equal to 40%, the included angle between the optical axis of the front polarizer 1 far away from the human eye and the horizontal plane is 0 degree, and the included angle between the optical axis of the rear polarizer 11 near the human eye and the optical axis of the front polarizer 1 is 70 degrees to 80 degrees;
when the front polarizer 1 and the rear polarizer 11 are EWV series polarizers, the stretching direction of the optical axis of the front polarizer 1 is consistent with the horizontal direction, and the stretching direction of the optical axis of the rear polarizer 11 is 90 degrees;
the polarized liquid crystal sunglasses are externally applied with matched driving voltage: the shading area of the polarized liquid crystal sunglasses is gradually formed along with the rise of an external driving voltage, the blackness is gradually improved, the blackness is not increased after the blackness and the width reach a certain value, and then the polarized liquid crystal sunglasses move from top to bottom in parallel along with the rise of the voltage.
In order to meet the requirement of the 0-degree polarized liquid crystal sunglass lens, the key technical scheme of the invention is as follows:
1. the visual direction design of the polarized liquid crystal sunglasses comprises the following steps: designing the visual direction between 7 points and 8 points of the right rotation of the left spectacle lens; the right-eye lens is designed from 4 points to 5 points in the left rotation direction, and the included angle between the optical axis of the polaroid on the side of the lens far away from eyes and the horizontal plane is 0 degree through the adjustment of the viewing direction, so that the requirement of 0 degree polarization is met.
2. Adjusting the box structure of the polarized liquid crystal sunglasses: by comparative analysis, the width of the light-shielding region is gradually widened from the design of 6-3 micron box structure. The structure of the polarized liquid crystal sunglass lenses on the market at present is 5 to 6 microns, so that the range of a shading area is narrow. The invention limits the diameter of the box structure (box support sheet or plastic ball) to 3-4 microns, and widens the shading area of the polarized liquid crystal sunglasses lens.
3. Selecting a polaroid of the polarized liquid crystal sunglass lens: through comparative analysis, the transmittance of the polaroid has a corresponding relation with the blackness and the width of the shading area. The higher the transmittance of the polaroid is, the lower the blackness of the shading area is, and the wider the width is; the lower the transmittance of the polarizer, the higher the blackness of the shading area and the narrower the width. The invention selects the polaroid with high transmittance, the transmittance is more than or equal to 40 percent, the blackness of the shading area is sacrificed, and the width of the shading area is widened. In order to meet the requirement of partial customers on the high blackness of the shading area, EWV series polarized light with wide visual angles is found through comparison and analysis, and the width of the shading area is widened while the blackness of the shading area is ensured.
4. Matching the optical axis and the visual direction of a polaroid of the polarized liquid crystal sunglass lens: through comparison, when the high-transmittance polaroid is selected, the width of the shading area is the narrowest and the blackness is the highest when the optical axes of the front and the rear sheets of the polarized liquid crystal sunglasses are orthogonal (the difference is 90 degrees). And deviating from the orthogonal, the width of the shading area is gradually widened, the blackness is gradually reduced, and the included angle between the shading area and the horizontal direction is gradually deflected. The width, blackness and angle of the shading area are considered, the included angle between the optical axis of the front polarizer far away from one side of human eyes and the horizontal plane is 0 degree, the requirement of 0-degree polarized light is met, the included angle between the optical axis of the rear polarizer close to one side of human eyes and the included angle between the optical axis of the front polarizer far away from one side of human eyes is 70-110 degrees, the blackness is sacrificed to widen the shading area of the polarized liquid crystal sunglass lens, and the shading area of the polarized liquid crystal sunglass lens is adjusted to be close to the horizontal direction. For the polarized liquid crystal sunglasses requiring high blackness of the shading area, EWV series of polarized light sheets with wide visual angles are used, the stretching direction of the optical axis of the EWV series of polarized light sheets and the horizontal included angle are 0 degrees and are consistent with the friction direction of the front PI oriented film in the polarized liquid crystal sunglasses box in a pointing mode, the stretching direction of the optical axis of the rear polarized light sheets and the horizontal included angle are 90 degrees and are consistent with the friction direction of the rear PI oriented film in the polarized liquid crystal sunglasses box in a pointing mode, therefore, the shading area of the polarized liquid crystal sunglasses can be widened, although the direction of the shading area cannot be changed, the influence of the inclined shading area is reduced through the widening of the shading area.
5. Matching of external driving voltage of the polarized liquid crystal sunglasses: the shading area of the polarized liquid crystal sunglasses is gradually formed along with the rise of an external driving voltage, the blackness is gradually improved, the blackness is not increased after the blackness and the width reach a certain value, and then the polarized liquid crystal sunglasses move from top to bottom in parallel along with the rise of the voltage. The specific implementation method is that the saturation voltage of the polarized liquid crystal sunglasses is greater than or equal to the driving voltage: the maximum value of the driving voltage applied to the liquid crystal sunglasses and the saturation voltage of the polarized liquid crystal lenses are within +/-0.2V. After the shading area of the polarized liquid crystal sunglasses is formed and the blackness and the width are reached, the voltage is not increased any more, and the effect of the upper depth and the lower depth is maintained.
Through the adjustment and the matching of the 5 key technologies, the requirements of 0-degree polarization are met, the display effect of the upper part and the lower part is achieved, and the requirements of the polarized liquid crystal sunglasses are met.
