Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sun glasses, in particular to a 0-degree polarized and gradient color liquid crystal sun lens. BACKGROUND

[0002] In the prior art, the Chinese patent application for invention with the patent number 202010548168.1 discloses a 0-degree polarized liquid crystal sun lens, which comprises a left eye lens and a right eye lens, wherein the left eye lens and the right eye lens each comprise, from front to back, a front polarizing plate, a front glass substrate or a flexible film, a front ITO electrode, a front PI alignment film, a cell support plate, a rear PI alignment film, a COM electrode, a rear ITO glass substrate, and a rear polarizing plate. An electrically conductive adhesive, edge sealing adhesive, and a glass frame support plate are arranged between one end of the front ITO glass substrate and the rear ITO glass substrate, and sealing adhesive is arranged between the other end. The viewing direction of the left eye lens is designed to be right rotation 7 to 8 points, and the viewing direction of the right eye lens is designed to be left rotation 4 to 5 points. The diameter of the cell support plate is 2 to 5 microns. The front polarizing plate and the rear polarizing plate are high-transmittance polarizing plates or EWV series polarizing plates. When the front polarizing plate and the rear polarizing plate are high-transmittance polarizing plates, the transmittance is required to be greater than or equal to 40%. The optical axis of the front polarizing plate away from the human eye side forms a 0-degree angle with the horizontal plane, and the optical axis of the rear polarizing plate close to the human eye side forms a 70-degree to 90-degree angle with the optical axis of the front polarizing plate. When the front polarizing plate and the rear polarizing plate are EWV series polarizing plates, the stretching direction of the optical axis of the front polarizing plate is consistent with the horizontal direction, and the stretching direction of the optical axis of the rear polarizing plate is 90°.

[0003] In order to meet the 0-degree polarization, the viewing direction of the left eye lens is designed to be right rotation 7 to 8 points, and the viewing direction of the right eye lens is designed to be left rotation 4 to 5 points. Although the thus-produced lens can achieve the upper deep and lower shallow of the shading area under the condition of meeting the 0-degree polarization, the gradient of the shading area of such a lens is still inclined, not straight down, as shown in Figure 1 Therefore, the present application proposes a 0-degree polarized and gradient color liquid crystal sun lens that can truly achieve the 0-degree polarization and the gradient from top to bottom. SUMMARY

[0004] The purpose of the present application is to provide a 0-degree polarized and gradient color liquid crystal sun lens that solves the above problems.

[0005] The application discloses a 0-degree polarization and gradient color liquid crystal sun lens, which comprises a left eye lens and a right eye lens.

[0006] When the front polarizing plate and the rear polarizing plate are high-transmittance polarizing plates, the transmittance is required to be greater than or equal to 40%, the angle between the optical axis of the front polarizing plate far from the human eye and the horizontal plane is 35 to 45 degrees, and the angle between the optical axis of the rear polarizing plate close to the human eye and the optical axis of the front polarizing plate is 90 to 110 degrees.

[0007] When the front polarizing plate and the rear polarizing plate are low-polarization polarizing plates, the polarization degree is required to be less than or equal to 95%, the angle between the optical axis of the front polarizing plate far from the human eye and the horizontal plane is 35 to 45 degrees, and the angle between the optical axis of the rear polarizing plate close to the human eye and the optical axis of the front polarizing plate is 90 to 110 degrees.

[0008] Further, the wave plate is a quarter wave plate or a half wave plate.

[0009] Further, the light shielding area of the polarizing liquid crystal sun lens is in the horizontal direction.

[0010] Further, the light shielding area of the polarizing liquid crystal sun lens is formed by matching the saturation voltage and the driving voltage, and the voltage is not increased after the blackness and the width are reached, so that the effect of deepening from top to bottom is maintained.

[0011] Compared with the prior art, the application has the beneficial technical effects that:

[0012] The application sets the wave plate at the front end of the front polarizing plate, so that the incident light is deflected after passing through the wave plate, the passing amount of the rear polarizing plate is increased or reduced, and the viewing direction of the lens is matched, so that the light shielding area is deepened from top to bottom under the condition of 0-degree polarization.

[0019] like Figures 1-3 As shown, a 0-degree polarized liquid crystal sunglasses lens capable of gradient color includes a left lens and a right lens. Both the left and right lenses, from front to back, sequentially include a front polarizer 1, a front ITO glass substrate 2, a front ITO electrode 3, a front PI alignment film 6, a housing support sheet 7, a rear PI alignment film 8, a COM electrode 9, a rear ITO glass substrate 10, and a rear polarizer 11. Conductive adhesive 13, edge sealing adhesive 4, and a frame glass support sheet 5 are disposed between one end of the front ITO glass substrate 2 and the rear ITO glass substrate 10, and sealing adhesive 12 is disposed between the other ends. The front polarizer 1 and the rear polarizer 11 are high-transmittance polarizers or EWV series polarizers; the polarized liquid crystal sunglasses lens is externally driven by a matching voltage, and the light-blocking area of ​​the polarized liquid crystal sunglasses lens is gradually formed as the external driving voltage increases, and the blackness gradually increases. After reaching a certain blackness and width, it no longer increases, and then moves parallel from top to bottom as the voltage increases. The feature is that: a wave plate 14 is provided on the front end surface of the front polarizer 1, and a TAC plate 15 is provided on the outer side of the wave plate 14; the viewing direction of the left lens is designed to be 6 o'clock, and the viewing direction of the right lens is designed to be 6 o'clock.

[0020] When the front polarizer 1 and the rear polarizer 11 are high-transmittance polarizers, the transmittance is required to be greater than or equal to 40%. The optical axis of the front polarizer 1 on the side away from the human eye is at an angle of 35 degrees to 45 degrees with the horizontal plane, and the optical axis of the rear polarizer 11 on the side closer to the human eye is at an angle of 90 degrees to 110 degrees with the optical axis of the front polarizer 1.

[0021] When the front polarizer 1 and the rear polarizer 11 are low-polarization polarizers, the polarization degree is required to be less than or equal to 95%, the angle between the optical axis of the front polarizer far from the human eye and the horizontal plane is 35 to 45 degrees, and the angle between the optical axis of the rear polarizer close to the human eye and the optical axis of the front polarizer is 90 to 110 degrees;

[0022] The wave plate is a quarter wave plate or a half wave plate.

[0023] The light blocking area of the polarized liquid crystal sun lens is formed by matching the saturation voltage and the driving voltage of the polarized liquid crystal sun lens. When the blackness and the width are reached, the voltage is no longer increased, and the effect of maintaining the deep upper and shallow lower is maintained.
