  • ORGANIC ELECTRO LUMINESCENSE DISPLAY APPARATUS AND APPLICATION THEREOF
    Publication number: 20130293597
    Abstract: A technology for reducing the so-called “phosphor burn-in” phenomenon where the variation of luminance arises by reducing display luminance of a certain pixel caused by deterioration in a display apparatus constituted by an organic electro luminescence element is provided. In the display apparatus, when displaying an image acquired by an image acquiring unit, luminance substantially same as average luminance of the acquired image is set to a non-display area where the image is not displayed.
    Type: Application

  • Display apparatus, mobile terminal and luminance control method in the mobile terminal
    Patent number: 7456852
    Abstract: When an input detection unit has detected that no user operation has been performed to an organic EL display apparatus for a predetermined period of time or when a processing detection unit has detected that a predetermined processing is being performed, the input detection unit or the processing detection unit outputs an instruction to a reference voltage adjusting unit to modify a reference voltage referenced by a DAC unit upon conversion to an analog output signal.
