  • Patent number: 9966035
    Abstract: Discussed is an organic light emitting display device and a driving method thereof, which reduce a size of corrected image data by using a color compression scheme to decrease a capacity of a memory, and reduce a size of an integrated circuit (IC) to increase a manufacturing yield. The method can include loading a compensation coefficient stored in a memory, correcting image data by applying the compensation coefficient to a data voltage supplied to a pixel, compressing, in different compression schemes, corrected image data of a color having high visual perceivability and corrected image data of a color having low visual perceivability, and synthesizing corrected image data of red, green, and blue pixels, which are compressed by the different compression schemes, to store the synthesized image data in a memory.

  • Patent number: 9659528
    Abstract: A method of compensating driving TFTs in an organic light emitting display device is discussed. According to an embodiment, the method includes applying a varied drain voltage to a drain of a specific driving TFT in one of a plurality of pixels; and compensating the specific driving TFT by the varied drain voltage, so as to maintain a constant drain-source voltage at the specific driving TFT.

  • Publication number: 20050232840
    Abstract: The present invention provides a photocatalytic oxide for car's side mirrors, which is coated on the chrome-coated layer of a front surface mirror to enhance the durability of the front surface mirror and to impart hydrophilicity to the front surface mirror, thus being capable of providing safe visibility for car drivers, as well as a producing method thereof. The producing method of the photocatalytic oxide comprises the steps of: stirring tetraethyl orthosilicate (TEOS) and titanium isopropoxide (TIP) in 2-propanol as a solvent, in which the volume ratio between the tetraethyl orthosilicate (TEOS) and the titanium isopropoxide (TIP) is 50:50, 30-50:40 or 20-40:30 while the amount of the solvent is maintained at a constant; subjecting the stirred mixture to a reaction; washing the reacted material with water/alcohol by centrifugation; separating the water/alcohol; and collecting a hydrophilic coating solution.
