230的偏光效果而被偏极化。 230 polarizing effect is polarization. 之后,偏极化的光线会穿过液晶层204,并 Thereafter, the polarized light will pass through the liquid crystal layer 204, and

且由于液晶分子的排列方式电压所影响,因此液晶可以改变偏极化光线的 And due to the influence of the arrangement of the voltage of the liquid crystal molecules, the liquid crystal can be changed and therefore the light polarization

偏光角度,而不同的偏光角度造成出来的光线强度会不同,不同强度的光 Polarization angle, resulting in different angles of polarization out of the light intensity will be different, different light intensities
