Abstract: A display device includes: a display panel including a plurality of pixels; and a panel driver that drives the display panel at a target refresh rate different from a previous refresh rate. The panel driver includes: a comparator which compares a difference value between the previous refresh rate and the target refresh rate with a reference value generated by multiplying the previous refresh rate by a predetermined reference percentage; and a determiner which determines a final count of at least one compensation frame to be inserted between a previous driving frame operating at the previous refresh rate and a target driving frame operating at the target refresh rate when the difference value is not less than the reference value, where the final count is a total number of the at least one compensation frame, and a natural number.

Abstract: This application relates to an active current compensation device which actively compensates for a noise occurring in a common mode in each of two or more high-current paths. In one aspect, the active current compensation device includes a sensing unit configured to generate an output signal corresponding to a common-mode noise current on each of the two or more high-current paths, and an amplification unit configured to amplify the output signal to generate an amplified current. The device may also include a compensation unit configured to generate a compensation current on the basis of the amplified current and allow the compensation current to flow to each of the two or more high-current paths, and a malfunction detection unit configured to detect a malfunction of the amplification unit. The malfunction detection unit and at least a portion of the amplification unit may be embedded in one integrated circuit (IC) chip.

Abstract: A method of manufacturing a composite material through a wet compression molding (WCM) process is disclosed. The internal pressure of a mold is controlled so that productivity may be improved due to process automation through application of a resin using a robot. Quality of the composite material may be improved due to minimization of deformation of a foam core through control of the internal pressure of the mold.

Abstract: Disclosed are an electrolyte membrane for a lithium-air battery, a method of manufacturing the same, a cathode for a lithium-air battery, a method of manufacturing the same, and a lithium-air battery including the electrolyte membrane and the cathode. Particularly, the lithium-air battery includes i) an electrolyte membrane, which is manufactured using an inorganic melt admixture including two or more nitrogen-oxide compounds and thus may have a very low eutectic point, and ii) a cathode, which is manufactured by reducing a metal at a fast speed on a carbon material. As such, the lithium-air battery is capable of stably operating even at low temperatures and providing high power output.
