  • Patent number: 8766958
    Abstract: A gate driving circuit unit, a gate driving circuit and a display device are disclosed. The gate driving circuit unit comprises: a first clock signal control module, an input signal control module, a third clock signal control module and a fourth clock signal control module, wherein the first clock signal control module comprises a driving unit and a clock feed-through suppressing unit. The driving unit transmits a first clock signal to an output port after being switched on. The clock feed-through suppressing unit couples the control end of the driving unit to a signal output interface under control of the first clock signal. The input signal control module provides the driving voltage for the driving unit under control of an input pulse signal. The third clock signal control module provides the shutdown voltage for the driving unit.

  • Patent number: 8704980
    Abstract: A display panel comprises a first and a second substrates and a BP liquid crystal layer. A first electrode is provided on the first substrate, a second electrode is provided on the second substrate, and reflection portions each having a first and a second reflection surfaces are provided between the first and second substrates. When light is transmitted to the panel, the light is reflected on the first reflection surface of the reflection portion and the light after the first reflection is transmitted to an adjacent reflection portion through the liquid crystal layer and is reflected on the second reflection surface of the adjacent reflection portion. When different voltages are applied, the liquid crystal layer will shift the phase position of the light passing therethrough, while when there is no voltage, the liquid crystal layer will not shift the phase position of the light passing therethrough.
