  • Patent number: 11970235
    Abstract: An adaptive vehicle headlight is provided for being installed on a vehicle body for use. The adaptive vehicle headlight includes a light body, an optical lens, a driver, and a control unit. The optical lens, the driver, and the control unit are integrated into the light body. In practice, the optical lens can optionally include a light distributing member. The control unit can cause an operation of the driver according to a tilt angle of the vehicle body, such that the optical lens and/or the light distributing member are rotated to a predetermined angle, so as to produce an illumination pattern in a horizontal state.

  • Publication number: 20240105121
    Abstract: An electronic device includes a substrate, a first silicon transistor, a second silicon transistor and a first oxide semiconductor transistor. The first silicon transistor, the second silicon transistor and the first oxide semiconductor transistor are disposed on the substrate. The first silicon transistor has a first terminal electrically connected to a first voltage level, a second terminal and a control terminal. The second silicon transistor has a first terminal electrically connected to the second terminal of the first silicon transistor, a second terminal electrically connected to a second voltage level, and a control terminal electrically connected to the control terminal of the first silicon transistor. The first oxide semiconductor transistor has a first terminal electrically connected to the first terminal of the second silicon transistor. Wherein, a voltage value of the first voltage level is greater than a voltage value of the second voltage level.
