  • Patent number: 11249328
    Abstract: 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.

  • Patent number: 10886941
    Abstract: A pulse density modulation method includes the following steps: S01, obtaining a number of bits n of a binary density value d, setting a number of bits of a counter as n, an initial value of the counter is 0 or 1; S02, searching for a rightmost 1: obtaining a number of bits j of the rightmost 1 of a current value i of the counter counted from right to left; a number in the counter is a binary number; a minimum value of j is 1; S03, determining whether corresponding bits are equal; S04, adding the value i of the counter by 1, proceeding to a next period, and turning to the step S02.
