Dimming glass and glass module

Abstract

The embodiment of the invention discloses dimming glass and a glass module. The dimming glass comprises a reflective half-wave plate, a reflective polaroid and a liquid crystal dimming structure located between the reflective half-wave plate and the reflective polaroid. The light-transmitting axis direction of the reflective half-wave plate is perpendicular to the light-transmitting axis direction of the reflective polaroid; in the light rays incident from one side of the reflecting surface of the reflective half-wave plate, the light rays with the polarization direction parallel to the first direction transmit the reflective half-wave plate, the light rays with the polarization direction perpendicular to the first direction are reflected by the reflective half-wave plate, and the polarization direction is rotated by 90 degrees; in the light incident from any side of the reflective polarizer, the light whose polarization direction is parallel to the second direction transmits the reflective polarizer, and the light whose polarization direction is perpendicular to the second direction is reflected by the reflective polarizer. According to the embodiment of the invention, the problem that an existing dimming glass mode is fixed is solved, controllable switching between a one-way privacy mode and a non-privacy mode can be realized, use requirements in different scenes are better met, and the use experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a dimming glass and a glass module. Background technique [0002] At present, dimming glass is more and more widely used in the fields of construction and transportation. There are already high demand for dye liquid crystal dimming glass in the fields of automobiles, high-speed rail, and passenger aircraft. [0003] As far as the automotive field is concerned, the automotive glass is generally composed of laminated glass and a metal reflective layer. The metal reflective layer forms a semi-transparent and semi-reflective effect on the light inside the car. Due to the high intensity of external light, it presents a mirror surface from the outside. From the inside, the external light transmittance is still high, thus ensuring a certain degree of visibility, thereby realizing the internal privacy mode. [0004] However, in some scenarios, automotive glass...

Problems solved by technology

[0004] However, in some scenarios, automotive glass also has application requirements for two-sided light transmission, that is, non-privacy mode, while the existing automotive glass structure can only achieve a single light transmission mode, and cannot achieve non-privacy mode, and cannot achieve privacy mode and non-privacy mode. The switching of privacy mode cannot achieve flexible control, and the user experience is poor
