Patent number: 11249328Abstract: A one-way glass based on the persistence of vision of human eyes includes a double glazing or a single glazing. The double glazing includes a switchable glass with electrically controllable and adjustable light transmittance, and a luminous glass that is electronically controlled to emit light. The luminous glass is a transparent glass. The switchable glass and the luminous glass are controlled by pulse signals of a pulse controller. When the luminous glass emits light, the switchable glass does not transmit light. When the switchable glass transmits light, the luminous glass does not emit light. Dot-matrix LED light sources are uniformly provided on the single glazing. A side of the dot-matrix LED light source facing indoors is provided with a light-shielding layer. A transparent gap is formed between adjacent dot-matrix LED light sources.Type: GrantFiled: December 16, 2019Date of Patent: February 15, 2022Assignee: HANGZHOU QISU TECHNOLOGY CO., LTD.Inventor: Nan Xia
