Abstract

The invention discloses a polarizer and a display device with the same. The polarizer comprises a polarizing layer, a protective layer, a conversion layer. The protective layer is used for protectingthe polarizing layer; the conversion layer has a transparent state and a specular reflection state; the polarizing layer is located between the protective layer and the conversion layer, and the conversion layer is converted between a transparent state and a specular reflection state by changing a voltage applied to the conversion layer. The polarizer is provided with the conversion layer capableof realizing mutual switching of reflection and transmission, and different states can be converted according to requirements so as to adapt to a use environment, so that the utilization rate of lightis improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a polarizer and a display device capable of switching between reflection and transmission. Background technique [0002] The existing liquid crystal display (Liquid Crystal Display, LCD) not only has the characteristics of light and thin, small size, but also has the advantages of no radiation, low power consumption and relatively low manufacturing cost. dominate. [0003] A liquid crystal display mainly includes a first substrate, a second substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate. Traditional liquid crystal displays mainly rely on the illumination of the backlight to display images. Depending on the light source used, liquid crystal displays mainly include reflective, transmissive, and transflective. There are two display modes for transflective liquid crystal displays, one is in a dark environment, m...
