  • Patent number: 11953596
    Abstract: A light detection and ranging (lidar) device includes: a lower base; an upper base; a laser emitting unit for emitting a laser in a form of a point light source; a nodding mirror for transforming the laser in the form of the point light source to a line beam pattern which is perpendicular to the lower base, wherein the nodding mirror reflects the laser emitted from the laser emitting unit; a polygonal mirror for transforming the line beam pattern to a plane beam pattern and receiving a laser reflected from an object; and a sensor unit for receiving the laser reflected from the object via the polygonal mirror.

  • Patent number: 11443710
    Abstract: A display interface device capable of reducing power consumption is disclosed. In the display interface device, a timing controller configured to compare input pixel data in horizontal line units and operate in a low power mode according to a result of comparison between an input time of horizontal lines having the same pixel data and a reference time in the horizontal line units. The timing controller operates in any one of a first low power mode for transmitting a training pattern and a second low power mode including a first duration during which data transmission and reception are stopped and a second duration during which the training pattern is transmitted, according to the result of comparison between the input time of horizontal lines having the same pixel data and the reference time.
