  • Patent number: 11906776
    Abstract: A backlight module includes a backplane, a light guide plate, a light bar assembly, and fixing adhesive tape. The backplane includes a bottom plate, a counter plate and a side plate connected to form an accommodating space. The light guide plate is in the accommodating space. The light bar assembly is in a U-shaped slot of the backplane and comprises a flexible circuit board and a light-emitting component. The flexible circuit board is on a side of the light guide plate facing away from the bottom plate, and the light-emitting component is at a side surface of the light guide plate. The fixing adhesive tape is between the counter plate and the flexible circuit board. The orthographic projection of the fixing adhesive tape on the bottom plate does not overlap the orthographic projection of the light-emitting component on the bottom plate.

  • Patent number: 10871606
    Abstract: The present disclosure relates to a field of display technologies and provides a light diffusing component, a backlight component having the same, and a display device. The light diffusing component may include a main body, a protruding portion, and a reflecting portion. The protruding portion is disposed on a side of the main body and protruded from the main body; the reflecting portion is disposed on the protruding portion and an edge region of the main body portion connected to the protruding portion, so as to reflect light incident from a lower portion of the light diffusing component. Light transmittance of the reflecting portion gradually increases in a direction away from a center of the diffusing component.

  • Publication number: 20200280953
    Abstract: A wideband, radio-frequency localization system may estimate the one-dimensional, two-dimensional or three-dimensional position and trajectory of a static or moving object. These estimates may have a high spatial accuracy and low latency. The localization may be determined based on phase or amplitude of a wideband signal in each frequency band in a set of multiple frequency bands. The localization may be based on a single shot of measurements across a wide band of radio frequencies, without frequency hopping. The measurements of the wideband signal may be taken over time and over space at multiple receivers. The localization may be based on measurements taken while a backscatter node remains in a first reflective state or in a second reflective state, rather than when the backscatter node is transitioning between reflective states. In some cases, the localization achieves sub-centimeter spatial resolution in each of three spatial dimensions.
