  • Patent number: 8922600
    Abstract: A display panel test apparatus that may include: a first measurer measuring first R, G, and B components of light emitted from a display panel at a first viewing angle; a second measurer measuring second R, G, and B components of light emitted from the display panel at a second viewing angle; a color coordinate calculator calculating a first xy color coordinate at the first viewing angle using the first R, G, and B components and calculating a second xy color coordinate at the second viewing angle using the second R, G, and B components; and a panel controller compensating a target color coordinate of the display panel to include the first xy color coordinate and the second xy color coordinate into a specification area on a color coordinate system.

  • Patent number: 8604403
    Abstract: An auto-focusing apparatus and method, the apparatus including an emission unit, the emission unit being configured to irradiate light on the organic light-emitting display apparatus; an optical system between the organic light-emitting display apparatus and the emission unit, the optical system being configured to adjust a position of the optical system on an optical axis and focus the irradiated light on the pixel unit; a light-receiving unit, the light-receiving unit being configured to receive light reflected by the organic light-emitting display apparatus and measure an intensity and a wavelength of the reflected light; and a controller, the controller being configured to receive the intensity of light measured by the light-receiving unit, control the position of the optical system, determine that the auto-focusing apparatus is focusing light onto the pixel unit when the intensity of light received by the light-receiving unit is a maximum value, and determine the position of the optical system as an opti

  • Patent number: 8426854
    Abstract: Exemplary embodiments of the described technology relate generally to display devices including dye-sensitized solar cells. The display device according to an exemplary embodiment includes a display element for displaying an image, and a dye-sensitized solar cell for converting light into electricity to offset the power consumption of the display element. The dye-sensitized solar cell includes a selective photo-absorption material for selectively absorbing light from at least one wavelength band.
