摘要： A liquid crystal projection layer for use in a glass, the glass including a first glass which includes a first surface and a second surface opposite to each other, the liquid crystal projection layer includes a transparent projection layer disposed on a side of the first glass close to the second surface and configured to display a projected image received from a projector; and a liquid crystal module disposed between the first glass and the transparent projection layer and configured to be switchable between a transparent mode and a privacy mode, wherein in the transparent mode, the liquid crystal module allows the projected image displayed on the transparent projection layer to be transmitted towards the first glass, and in the privacy mode, the liquid crystal module prevents the projected image displayed on the transparent projection layer from being transmitted towards the first glass.

摘要： An anti-fog glass includes a glass body configured as a single layer or a multilayer stack; an active anti-fog layer disposed on the glass body and heating up when being provided with power; and a passive anti-fog layer disposed on the glass body and inhibiting fog from forming on the passive anti-fog layer. The passive anti-fog layer is a super hydrophobic coating and/or hydrophilic coating. Both the active anti-fog layer and the passive anti-fog layer are simultaneously disposed on the glass body to inhibit fog from forming. In this way, in a region of the glass body not covered by the active anti-fog layer, the anti-fog function is achieved by the passive anti-fog layer to a certain degree; in addition, in a region where the passive anti-fog layer itself cannot provide a desired anti-fog level, the active anti-fog layer together with the passive anti-fog layer provide a better anti-fog effect.
