The invention provides a polarizing plate and a dimming window and belongs to the technical field of glass windows. A problem that an existing dimming window needs to be greatly adjusted to achieve light intensity adjustment is solved. The dimming window comprises two polarization plates, namely a first polarization plate and a second polarization plate with the same structure as the first polarization plate, wherein the first polarization plate and the second polarization plate are oppositely arranged in parallel; the sliding groove is fixed relative to the first polarizing plate, and the second polarizing plate is in sliding or rotating fit with the sliding groove; and the driving structure is used for driving the second polarizing plate to move or rotate in the sliding chute. The polarization plate comprises a plate body composed of a plurality of polarization units distributed in an array mode, and the vibration transmission direction of each polarization unit is different from the vibration transmission direction of the adjacent polarization unit. The method has advantages of small adjustment amplitude, wide application range and the like.
本发明提供了一种偏振板及调光窗,属于玻璃窗技术领域。它解决了现有调光窗需要进行大幅度调节后才能实现光线强度调节的问题。调光窗,包括两块偏振板:第一偏振板、与第一偏振板结构相同的第二偏振板,第一偏振板与第二偏振板相对且平行设置;与第一偏振板相对固定的滑槽,第二偏振板与滑槽滑动或转动配合;以及用于驱动第二偏振板在滑槽内移动或转动的驱动结构。偏振板包括由若干阵列分布的偏振单元构成的板体,偏振单元的透振方向和与之相邻设置的偏振单元的透振方向不同。本发明具有调节幅度小、应用范围广等优点。
