  • Patent number: 11263989
    Abstract: A display device includes a display panel, a data driver, a gate driver, and a controller. The display panel includes a plurality of pixels. The data driver provides data voltages to the plurality of pixels through data lines during an active period of a frame period and provides a blank voltage to the plurality of pixels through the data lines during a blank period of the frame period. The gate driver provides a gate-on voltage to the plurality of pixels through gate lines during the active period and provides a gate-off voltage to the plurality of pixels through the gate lines during the blank period. The controller controls the data driver and the gate driver. The blank voltage increases and the gate-off voltage increases, when a time in the blank period reaches a predetermined time.

  • Publication number: 20210096423
    Abstract: A display device may include a backlight unit, a display panel, and a backlight driver, and a panel driver. The backlight unit may include light source blocks including a first light source block. The display panel may include dimming regions including a first dimming region and respectively overlapping the light source blocks. The first dimming region may overlap the first light source block. The backlight driver may control a turn-on period and a turn-off period of each of the light source blocks. The panel driver may sequentially provide scan signals to the dimming regions for controlling light transmission of the dimming regions. A turn-off period of the first light source block may start before a scan period of the first dimming region and may end after the scan period of the first dimming region. The first dimming region may receive corresponding scan signals in the scan period.

  • Publication number: 20210015187
    Abstract: The present invention relates to a vinyl glove with a cosmetic pack function having a shape of a finger glove having finger portions and a body, the vinyl glove including: cutting lines formed along the finger portions to separate given portions of the finger portions from the body; finger bonding portions formed toward the body by given distances with respect to the cutting lines in such a manner as to thermally bond tops and undersides of the finger portions to prevent the cosmetic liquid from leaking to the outside; and a wrist bonding portion formed inward toward the body by a given distance with respect to an insertion portion formed on a wrist portion of the body in such a manner as to thermally bond top and underside of the body to prevent a cosmetic liquid from leaking to the outside.

  • Patent number: 10839755
    Abstract: A display device includes a display panel including gate lines, data lines, and pixels individually connected to a corresponding gate line and data line, a gate driver driving the gate lines, a data driver driving the data lines, and a driving controller. The driving controller receives, from an external source, first image signals and a variable frequency signal indicating an operation frequency (frame rate) for the display device. The driving controller converts the first image signals to second image signals by adding a compensation value corresponding to the operation frequency to the first image signals, and outputs the second image signals to the data driver. Embodiments may compensate for luminance reduction/variation and reduce image artifacts that otherwise occur due to variable frequency operation. An alternative embodiment dynamically controls an amount of light output from a backlight according to the variable frequency signal.

  • Patent number: 9111506
    Abstract: A display device includes a plurality of pixels arranged in matrix, a plurality of gate lines, a plurality of data lines, and a gate driver connected to the plurality of gate lines. The gate driver receives a first scan start signal, a second scan start signal and clock signals and outputs a gate-on voltage to each of the plurality of gate lines. The gate driver outputs the gate-on voltage to the plurality of gate lines such that the gate-on voltages do not overlap with each other when the gate driver receives the first scan start signal. The gate driver outputs the gate-on voltage to at least two of the gate lines at substantially the same time when the gate driver receives the second scan start signal.
