  • Publication number: 20240135858
    Abstract: A display device includes pixels connected to scan lines and data lines, each pixel including a driving transistor and at least one light emitting element, and a timing controller configured to generate output data using external input data. The timing controller includes a first compensator configured generate first data by correcting the external input data using at least one of optical measurement information, a threshold voltage of each of the driving transistors, mobility information, dimming information, and temperature information, and an afterimage compensator configured to generate second data based on age information of each light emitting element and the first data, generate third data based on a current amount corresponding to the first data and a current amount corresponding to the second data, and generate the age information by accumulating the third data.

  • Publication number: 20240118196
    Abstract: In the case of a gas in which several gases are mixed, a type and concentration of the gas may be incorrectly measured when measured using only an optical band-pass filter. The invention of the present application is directed to providing a technology in which a plurality of broadband band-pass filters having overlapping regions are provided to calculate a magnitude of absorption for each wavelength band for light passing through each broadband band-pass filter, thereby identifying the presence of a gas of interest and the presence of a gas other than the gas of interest.

  • Patent number: 10358375
    Abstract: Disclosed herein is a scribing wheel having a predetermined thickness and a disk shape. The scribing wheel includes: a wheel body configured in such a way that at least a peripheral edge portion thereof is gradually reduced in thickness from the center to the radial outside; and a cutter part including recesses and cutting blade teeth which are alternately arranged along the peripheral edge portion. Each recess is formed by a combination of side recess portions formed in opposite side surfaces of the peripheral edge portion of the wheel body and an edge recess portion formed in the peripheral edge of the wheel body.

  • Patent number: 7098008
    Abstract: The present invention relates to primers for diagnosis of one or more kinds of cancers and a diagnosis kit comprising said primers. The primers are made from highly homologous areas of twelve MAGE subtypes and eight GAGE subtypes. The diagnostic kit comprising the said primers can detect six MAGE subtypes and eight GAGE subtypes respectively. The invention also includes methods for using the primers to diagnose the onset of cancer, to monitor the progression of disease, and to correlate the gene expression to the prognosis of disease.
