Abstract: An optical touch panel apparatus for detecting a position of a light blocking object on a flat panel 2 includes a plurality of light emitting elements and light receiving elements arranged along a side of the rectangular flat panel 2. The optical touch panel apparatus sets a peripheral area on the flat panel 2, and performs position detection in an area other than the peripheral area while not performing position detection within the peripheral area. The peripheral area is an area proximal to the light emitting elements or light receiving elements, in which resolution for position detection is deteriorated and unsatisfactory light blocking is likely to occur. By limiting the area for which position detection is performed to the area other than the peripheral area, deterioration in resolution for position detection and occurrence of unsatisfactory light blocking can be prevented, making it possible to stably perform position detection.

Abstract: A high luminance display apparatus is provided. When a spectral radiance of a backlight at a time point of factory shipment is less than a spectral radiance of external light, a CPU generates a correction matrix for performing color correction so that color produced by external light, i.e., color produced by reflection light of external light by a half mirror conforms to color produced by only irradiation light of the backlight, transmits the generated correction matrix to a video image signal processing section as parameter information, and causes execution of color correction based on the parameter information. The CPU generates a correction matrix based on a spectral radiance of external light detected by a second spectral radiance sensor, a spectral radiance of the backlight detected at the time point of factory shipment, and spectral transmittance of a color filter as well as a color-matching function.

Abstract: The optical touch panel device can optically detect a position of an object on a display screen at a plurality of kinds of position-detection resolutions, and sets a position-detection resolution according to a screen resolution of the display screen or an image resolution of an image to be displayed on the display screen. The optical touch panel device sets the position-detection resolution so that an average value of distances between optical paths used for position detection over the whole display screen is smaller than a dot pitch or a pixel pitch and is as close as possible to the dot pitch or the pixel pitch. The capability of position detection matches the capability of image display in the optical touch panel device, thereby user does not have a feeling of strangeness about an image displayed according to position-detection resolution.
