Embodiment Construction

[0025] Depend on figure 1 As is well known, the gradient polarized liquid crystal light valve is composed of polarizers 1, 2, indium tin oxide conductive layer 3, alignment layer 4, TN type liquid crystal 5, edge sealant 6, and control electrodes 7, 8. The polarizers 1 and 2 are composed of two cellulose acetate sheets 2-1 with a gradient polarizing film 2-2 sandwiched between them, and the edge sealant 6 seals both ends of the TN type liquid crystal 5 .

[0026] Depend on figure 2 It is a schematic diagram of the front view effect of the liquid crystal light valve in this embodiment. Apply a 2-3V 100Hz oscillating voltage to both ends of the gradient polarized liquid crystal light valve control electrodes 7 and 8, and the upper part of the light valve will turn dark black within 0.1 second, and the transparency will gradually increase as the degree of polarization decreases downward until the lower end of the light valve becomes transparent. After the power is cut off, th...

Abstract

The invention relates to a graded polarizing liquid crystal light valve and a manufacturing method thereof. The graded polarizing liquid crystal light valve comprises a left polaroid (1), a right polaroid (2), an indium-tin oxide conducting layer (3) in the middle, an oriented layer (4), a TN liquid crystal (5), an edge glue (6), a control electrode (7) and a control electrode (8), wherein the polaroid (1) and the polaroid (2) comprise two cellulose acetate strips (2-1) and a graded polarizing membrane (2-2) sandwiched between the two cellulose acetate strips. In the invention, the liquid crystal light valve is manufactured by using the resin material of the polaroids, liquid crystal glass is saved, the weight is reduced by one half, the liquid crystal light valve has resistance to impactcollision and does not have the problem of breaking, the use of the graded polarizing membrane takes account of the contradictory relation between the light blocking degree and light transmitting degree, the visual field of a driver is clear when the liquid crystal light valve is used at night, and the light transmittance reaches national standards.

Description

[0001] The invention relates to the production field of liquid crystal products, in particular to a gradient polarized liquid crystal light valve and a manufacturing method thereof. Background technique [0002] As we all know, the technology of combining liquid crystal screens made of glass materials with large-area uniformly dyed polarizers has been widely used in LCD TVs, notebook computers and other products that require liquid crystal display, but it is not used in the production of eyeglass lenses. There is a practical problem that the optical glass material is made into a liquid crystal light valve and an ordinary polarizer is combined to make a lens, which is heavy in weight and easily broken by collision. It is far from meeting the national requirement that the light transmittance of the driver's mirror must reach more than 75%, and it cannot meet the driver's perspective requirements on the liquid crystal light valve when driving at night. The development and applica...
