    Abstract: Embodiments of the present disclosure disclose a peep preventing device. The peep preventing device includes first electrodes and a transparent insulating body on a transparent substrate. The insulating body has recesses, the first electrodes are located in the recesses, respectively, and an area of a section, taken along a plane parallel to the transparent substrate, of each recess gradually reduces in a direction away from the transparent substrate. The peep preventing device further includes transparent second electrodes each of which includes a second electrode sidewall portion covering a sidewall of one of the recesses. Closed spaces are defined between the insulating body and the second electrodes and the transparent substrate, and electrophoretic liquids are contained in the closed spaces, respectively, and contain reflective charged particles adapted to adhere to the second electrodes when a first electric field is applied between the first electrodes and the second electrodes.

    Abstract: A display device and a driving method thereof are provided. The driving method includes supplying a first voltage Vp1 to a sub-pixel of the display device through data lines in a first stage of a control period for displaying an image. A time for displaying the image includes a plurality of control periods, and the control period includes the first stage and at least a second stage following the first stage. The driving method also includes supplying a second voltage Vp2 to the sub-pixel through the data lines in the second stage. A gate scanning frequency of the first stage is F1 and a gate scanning frequency of the second stage is F2. When the first stage ends, the sub-pixel has a pixel voltage Vp3, F1 |Vp3|.

    Abstract: In the invention, as the arrangement of the color filters of the sub-pixel units of every two adjacent pixel units in the row direction, from at least one group composed of two adjacent columns of pixel units in the row direction, is changed, so that the color filters of two adjacent sub-pixel units in the row direction, which belong to different two pixel units, have the same color. Moreover, position of the data line connected with the sub-pixel units with color filters of the same color is changed, so that the data line is provided at a side of one of the sub-pixel units with color filters of the same color far away from the other one thereof. Therefore, while the color mixing phenomenon is avoided, a part of the black matrix, which should be provided between the two adjacent sub-pixel units in the row direction, may be omitted.
