Abstract: An LED classification device classifies LEDs, the LEDs each including a combination of an LED element that emits a primary light and a phosphor that, upon excitation by the primary light, emits a secondary light having a longer wavelength than the primary light, the LEDs each emitting a combined light of the primary light and the secondary light, those ones of the LEDs whose primary lights having their chromaticities falling within a predetermined chromaticity range being classified as LEDs for use in a backlight of a liquid crystal display apparatus. The LED classification device calculates, for all of the LEDs to be classified, correction values for the chromaticities as obtained on the assumption that the primary lights have traveled through a color filter of the liquid crystal display apparatus, and correct chromaticities by subtracting the correction values from chromaticities obtained for all of the LEDs to be classified, respectively.

Abstract: An optical test equipment/method for display testing that features parallel testing/sensing configuration that covers spectrum and colorimetric quantities with spatial resolution is disclosed. In one embodiment, a spectra-camera, which is a hybrid system consisting of both a single-point spectrometer and an imaging colorimeter, can be configured for concurrent display artifact and parametric testing. An aperture mirror with a hole in the middle splits an image of a test display into two parts. One part of the image passes through the hole and is directed to the spectrometer for display parametric testing. The rest of the image is reflected off the aperture mirror for concurrent display artifact testing with the colorimeter. In another embodiment, a beam splitter can be used instead of an aperture mirror. In yet another embodiment, the single-point high accuracy spectrometer can be used to calibrate the low accuracy imaging colorimeter.

A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.
