The present invention relates to an abrasive disk that is excellent in workability and stability and has a low degree of fatigue applied to workers and tools, and a process for producing the same. The abrasive disc is excellent in stability by virtue of a high adhesive strength of each layer, has high flexibility, elasticity, and adhesiveness, and is lightweight per unit area. Thus, it has a low degree of fatigue applied to workers and expensive tools. In addition, according to the above production process, the abrasive disk can be continuously mass-produced.

A display device includes a timing controller configured to supply a first set signal to a data control signal line in a first frequency mode, and to supply a second set signal and a data signal to the data control signal line in a second frequency mode that is different from the first frequency mode, a data driver configured to recover the data signal supplied to the data control signal line according to a signal recovery characteristic value, to generate a plurality of data voltages based on the recovered data signal, and to adjust the signal recover characteristic value based on the first set signal and the second set signal, and a display unit including a plurality of pixels that emit lights with gray scales corresponding to the plurality of data voltages.

Display device and driving method thereof

A liquid crystal display device includes: a display panel including a plurality of pixels for displaying an image; a temperature sensor for sensing a temperature; an image data corrector for calculating correction parameters based on a grayscale change, calculating temperature parameters based on preset reference temperatures and the correction parameters, and correcting current image data to provide corrected image data based on the correction parameters and the temperature parameters; and a data driver for converting the corrected current image data into a data voltage and supplying the data voltage to the display panel. At least one of the correction parameters has a value that varies linearly with the sensed temperature and is based in part on the temperature parameters.
