  • Patent number: 11841586
    Abstract: A liquid crystal display has position-adjustable light sources. The light sources may be lamps, LEDs, or other emissive components. The light sources, however, are movable to adjust the locations or positions of their light outputs. The light sources ride upon electromagnet carriers. When currents are applied to the electromagnet carriers, each electromagnet carrier creates a corresponding magnetic field. The magnetic fields cause neighboring electromagnet carriers to attract or to repel, depending on the magnitude/polarity of the currents. The lateral and vertical positions of the electromagnet carriers may thus be adjusted by varying their respective currents and magnetic fields. Because the light sources ride on the electromagnet carriers, the light sources may be moved to refine an image generated by the liquid crystal display. The light sources, for example, may be moved to improve white/black contracts to reduce halo-effects.

  • Patent number: 9116061
    Abstract: An exemplary embodiment of a testing device for testing a pulling force includes a shell having a test platform, a load sensor mechanism, a control system, a drive and transmission mechanism and a material clamping mechanism. Two portions of a test object are clasped by the load sensor mechanism and the clamp. When the load sensor mechanism is driven to move further away from the clamp via the drive and transmission mechanism, a pulling force perpendicular to the test platform is generated between the two portions of the test object. The load sensor mechanism detects the pulling force and feeds back the detection to the control system.
