    Abstract: A driving method for pixel is configured to drive a first pixel and a second pixel. The driving method includes that a first output gray value of the first pixel and a second output gray value of the second pixel are set according to saturation. The saturation is decided according to an input gray value. The first pixel and second pixel are driven according to the first output gray value and the second output gray value. When the saturation is within a first value range or a third value range, the difference between the first output gray value and the second output gray value is less than the difference between the first output gray value and the second output gray value, when the saturation is within a second value range. The second value range is between the first value range and the third value range.

    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: 9500902
    Abstract: Disclosed herein is a display device switchable between a mirror mode and a display mode. The display device includes a display panel, a polarizing element and a reflective polarizer. The display panel has a light-emitting surface for emitting a polarized light. The polarizing element has an absorption axis, and is disposed on a side adjacent to the light-emitting surface. The polarizing element is switchable between a polarizing mode and a non-polarizing mode. When the polarizing element is operated in the polarizing mode, the polarizing element absorbs a polarized light in the polarization direction parallel with the absorption axis. When the polarizing element is operated in the non-polarizing mode, the polarizing element allows the polarized light emitted from the display panel to pass there through. The reflective polarizer is disposed between the display panel and the polarizing element.
