  • Patent number: 11403993
    Abstract: A light-emitting diode display device and a light-emission control method thereof are provided. The light-emitting diode display device includes a timing controller, multiple display pixels, and a scanning circuit. The display pixels form multiple display rows. The scanning circuit generates multiple scan signals and multiple light-emission signals that respectively drive the display rows. During a first data-writing time period of a first frame period, the timing controller provides multiple writing data to be respectively written into the display rows. During a light-emitting time period, the scanning circuit drives each of the light-emission signals to generate multiple pulses periodically according to a set period to drive the corresponding display rows. The light-emitting time period is after the first data-writing time period and before a second data-writing time period of a second frame period ends.

  • Publication number: 20170160182
    Abstract: The devices can improve rotational movement substantially without or with significant reduction in mechanical interference. The devices can be configured to independently rotate a module about two substantially aligned perpendicular axes. The devices can include a first motor; a second motor; a first frame, the first motor and the second motor within the first frame, the first motor and the second motor being adjacent; a second frame, the first frame being above the second frame; and a module rotatably disposed to the second frame. The first motor can be configured to cause the module and the second frame to rotate with respect to the first frame about the first axis. The second motor can be configured to cause the module to rotate with respect to the second frame about the second axis.
