  • 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.

  • Patent number: 11422035
    Abstract: Disclosed is a color and luminance measuring device including a filter unit including a case which covers the entire device and has a light incident part formed on one side thereof through which measured light emitted from an object to be measured is incident, a measurement unit which measures luminance and a color by receiving the measured light in the case, and a filter unit which is disposed on a movement path of the measured light in the case to selectively control the luminance of the measured light transmitted to the measurement unit and transmit the measured light, wherein the filter unit reduces the luminance of the measured light to a predetermined level when the measured light has luminance of a predetermined level or higher and transmits the measured light to the measurement unit.
