  • Patent number: 9818356
    Abstract: A display device includes a display panel including gate lines, data lines, and pixels connected to the gate line and the data lines, a gate driver driving the gate lines, a level shifter applying a gate clock signal to the gate driver, a data driver driving the data lines, a timing controller generating control signals to control the level shifter, the gate driver, and the data driver, and a backlight unit providing light to the display panel. The level shifter sets a voltage level of a gate-on voltage of the gate clock signal to a voltage level of a first gate-on voltage or a voltage level of a second gate-on voltage higher than the first gate-on voltage in response to a gate-on control signal.

  • Publication number: 20170166035
    Abstract: An air vent for a vehicle is provided. In particular, a diffusion air vent for a vehicle discharges air in a concentrated and diffused manner by controlling a discharge direction of the air. The air vent concentratedly and diffusedly discharges air by an air discharge mode change mechanism based on a dial rotation operation. Further, a damper is configured to be opened or closed based on the dial rotation operation to permit and interrupt air discharge.

  • Publication number: 20170076649
    Abstract: A display panel driving apparatus includes a data driving circuit, a gate driving circuit and a common voltage outputting circuit. The data driving circuit is configured to output a data signal based on image data to a data line of a display panel. The gate driving circuit is configured to output a gate signal to a gate line of the display panel. The common voltage outputting circuit is configured to output a common voltage according to grayscale values of the image data and set the common voltage in varying grayscale value intervals according to a decrease of the grayscale values of the image data.

  • Patent number: 8541811
    Abstract: There are provided a TFT, a TFT substrate using the TFT, a method of fabricating the TFT substrate, and an LCD. The TFT includes a source region, a drain region, and a gate electrode having an opening. The opening of the gate electrode is to enhance the light sensing ability of the TFT when it is used as a light sensor, since light is incident into a region where the opening is formed. The TFT including the gate having the opening can be used in a substrate of a flat display or an LCD using such a substrate. The above TFT can sense light incident from outside the display to adjust the brightness of the screen according to the external illumination.

  • Patent number: 8339534
    Abstract: A display device includes gate lines; data lines; charge control lines each including a charge control voltage input pad; first and second thin film transistors (TFTs) each including control and input electrodes connected to the gate and data lines, respectively; a first liquid crystal capacitor connected to an output electrode of the first TFT; a second liquid crystal capacitor connected to an output electrode of the second TFT; a charge control TFT including a control electrode and an input electrode connected to one of the charge control lines and the second pixel electrode, respectively; and a charge-down capacitor connected to an output electrode of the charge control TFT. A duration time of a turn-on voltage pulse applied to the charge control TFT is different from a duration time of a turn-on voltage pulse applied to the first TFT transistor or the second TFT.
