  • Patent number: 10332477
    Abstract: A display device includes a display array and a driving circuit. The display array includes at least one scan line. The driving circuit drives the display array and includes a timing controller and a gate driver. The timing controller controls a refresh rate of the display array at a first frequency or a second frequency, where the first frequency is higher substantially than the second frequency. The gate driver switches between supplying an enable voltage signal and a disable voltage signal to the scan line. Under the first or frequency, a corresponding first or second voltage difference exists between the enable voltage signal and the disable voltage signal. The first voltage difference is substantially greater than the second voltage difference, and the enable voltage signal has a same enable period.

  • Patent number: 9939715
    Abstract: A projection device is disposable into a display platform of a display rack having a plurality of display platforms, for directly projecting an image frame onto a projection screen of the display platform. The image frame projected to the projection screen is not reflected by any reflective mirror arranged between the projection device and the projection screen. A length of the image frame in a first direction is equal to at least ten times a length of the image frame in a second direction. Since no reflective mirror is arranged between the projection device and the projection screen, the projection device is more easily applicable to display racks.
