  • Publication number: 20220197467
    Abstract: Disclosed herein are a touch display device capable of solving distortion of a display image due to a difference in condition between touch nodes, and a method of driving the same. The touch display device includes a panel driver configured to drive gate lines and data lines of a panel and drive and sense touch electrodes, a timing controller configured to control an operation of the panel driver, and a touch controller configured to control touch electrode driving and a sensing operation of the panel driver, wherein the timing controller compensates a display signal for a difference in condition between a touch node where a touch occurs and a touch node where a touch does not occur or a difference in physical structure between the touch nodes.

  • Patent number: 11308840
    Abstract: The present disclosure relates to a technology for a low power operation of a display device. The present disclosure allows reducing power consumption by supplying image data of a pixel of a preceding line again for a pixel of a current line without transmitting new image data when image data are repeated in units of pixels.

  • Patent number: 11148097
    Abstract: The present invention relates to a low-temperature membrane separation device and method for capturing carbon dioxide at a high concentration, in which a gas mixture is passed through a membrane unit to thus separate carbon dioxide. The membrane unit includes a membrane for capturing carbon dioxide and is connected to a feed gas line, a retentate gas line and a permeate gas line. The method includes a first separation step of passing the gas mixture through a first membrane unit and a second separation step of passing the permeation gas, which is discharged to the permeate gas line connected to the first membrane unit, through a second membrane unit. The second separation step is performed at a temperature that is lower than a temperature at which the first separation step is performed.

  • Patent number: 10239015
    Abstract: This invention relates to a device for separating carbon dioxide that includes a self-recycling loop, and to a method of separating carbon dioxide, which serve to effectively separate carbon dioxide from a combustion gas using a separation membrane provided with the self-recycling loop. This invention adopts a self-recycling loop in which the residue gas passing through a specific separation membrane is introduced into another separation membrane and in which a permeate gas passing through the specific separation membrane is introduced back into the specific separation membrane. Accordingly, the concentration of carbon dioxide in the feed gas of the specific separation membrane is increased, which increases the concentration of the permeate gas to thus improve the separation performance of the separation membrane, thereby separating high-purity carbon dioxide.
