  • Publication number: 20220002099
    Abstract: An electric paper tray includes a base, a paper holding element pivotally mounted to at least one side of the base, a power unit arranged at the base, and a lifting module connected between the paper holding element and the power unit. The lifting module is movably mounted under the paper holding element. When the lifting module is driven by the power unit to move to a first position, with respect to the base, the lifting module drives the paper holding element to make the paper holding element rotate to a closed position, when the lifting module is driven by the power unit to move to a second position, with respect to the base, the lifting module drives the paper holding element to make the paper holding element rotate to an opened position.

  • Patent number: 11215525
    Abstract: A wafer-grade LED detection device and a wafer-grade LED detection method are provided. The wafer-grade LED detection device includes a light-generating module for providing a first light beam that passes through an LED wafer to be converted into a second light beam, a light-filtering module adjacent to the LED wafer for receiving the second light beam that passes through the light-filtering module to be converted into a third light beam, and a light-detecting module adjacent to the light-filtering module for receiving and detecting the third light beam. A wavelength range of the second light beam is restricted by the light-filtering module, so that a wavelength range of the third light beam is smaller than the wavelength range of the second light beam. When the third light beam is received by the light-detecting module, the light-detecting module can detect the third light beam for obtaining relevant information.

  • Publication number: 20210304703
    Abstract: Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.
