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.

Abstract: This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. In one embodiment, a narrowband instrument, such as a spectrometer or spectrograph, can be used for calibration of a wideband colorimeter, so that more accurate outputs can be provided. In one embodiment, an optical test equipment, which consists of both a wideband colorimeter and a narrowband spectrograph, can be used for providing a more accurately calibrated wideband colorimeter. As an example, a spectra-camera, which is a hybrid system consisting of both a wideband colorimeter and a narrowband spectrograph, can be used for simultaneous testing by both the wideband colorimeter and the narrowband spectrograph. By doing simultaneous testing, accurate calibration of the wideband colorimeter can be achieved. This specification further describes a mathematical model to characterize a wideband three channel colorimeter with a narrowband multiple channel spectrometer.

Abstract: In a method for spectroscopic measurement, a spectroscopic measurement equipment, and a generating method for a transformation matrix, a measured spectrum is converted into a spectrum by making a transformation matrix act on the measured spectrum. The transformation matrix is determined as follows. A known light measured spectrum is linearly projected to a linear space constituted by principal component vectors of the measured spectrum obtained by a reference measurement equipment to thereby convert the known light measured spectrum into a reference known light measured spectrum. The transformation matrix is determined so that an evaluation function, which is defined by a linear combination of a difference between an estimated spectrum obtained by making the transformation matrix act on the reference known light measured spectrum and a known light spectrum, and dispersions of respective components of the transformation matrix, takes an extreme value.

Abstract: The amount of light incident on a photoelectric conversion element is increased while stray light from a backlight below a light-transmitting substrate is prevented from being incident on the photoelectric conversion element. A light-blocking film is formed with a color filter covering a photoelectric conversion element over a light-transmitting substrate and a color filter covering a photoelectric conversion element in an adjacent pixel which overlap each other at the side with respect to the direction in which light travels. In addition, by providing a microlens over the color filter, light which is conventionally not detected is collected to a photoelectric conversion element, and accordingly the amount of light incident on the photoelectric conversion element is increased.
