摘要： It is an object of the present invention to provide an image display apparatus which enables cost reduction while being free from electromagnetic interference problems.A power supply circuit comprises, on a single circuit board, an AC inlet to which a power cord is connected from an external AC power supply, a filter circuit to which an inductance element is connected to suppress leakage of electromagnetic waves to the outside of the image display apparatus, and a switch which switches on/off an AC output supplied from the filter circuit. The circuit board of the power supply circuit is entirely covered by electromagnetic shielding means to shield electromagnetic waves. The electromagnetic shielding means is composed of, for example, a first shielding section which surrounds the lateral side of the circuit board and a second shielding section which covers the upper side of the circuit board. The second shielding section is formed of a part of the flat section of a rear cover of the image display apparatus.

摘要： The present invention solves the problem that the color temperature of initial setting is changed, when a PDP is driven for a long period of time, due to the non-uniform deterioration of red, green and blue fluorescent materials that is caused by the ultraviolet rays generated for discharge. Color temperature correction is performed by setting the numbers of discharge pulses for fluorescent materials in accordance with a discharge pulse number correction curve with respect to the cumulative elapsed driven time of a PDP.

摘要： An image display device for displaying images by using the digital signal processing and by making use of the sight emission of the phosphor. An static image is detected from an image signal data, and when the luminance level of the static image is high, the luminance level of the specific area is lowered, and when the luminance level of the static image is low, the luminance level of the specific area is increased. In this manner, it is possible to reduce image retention of the static image when the static image is displayed for a long time.

摘要： An area control section individually sets illumination intensity (light control value) of each backlight cell corresponding to each area of the display screen. A spatial filter corrects the light control values so that spatial distribution of the light control values becomes more moderate between adjoining areas. A black area control section sets the minimum value of the light control value based on a “black area” in the screen. A power control section corrects the light control values so that power consumption of the backlight does not exceed a limit value. A shading control section corrects the light control values to relatively lower brightness in the peripheral part of the screen compared to the central part of the screen. A micro-controller switches the operations of the above light control value correcting sections according to an image display mode selected by the user.

摘要： The present invention enables a liquid crystal display device using LEDs as a light source to reduce uneven brightness, increase efficiency of heat discharged from the LEDs, and provide area brightness control. The liquid crystal display device includes a liquid crystal display panel and a backlight. The backlight includes a light guide panel and a plurality of LEDs arranged on a line. The light guide panel includes a concave portion extending in a longitudinal direction of the light guide panel. A large number of LEDs are placed in the concave portion of the light guide panel. The plurality of LEDs arranged on a line emit light alternately in opposite directions. This configuration allows for uniform brightness distribution without forming a large number of concave portions in the light guide panel. Further, this configuration also allows for area brightness control by controlling a large number of LEDs by group.

摘要： A luminaire using LEDs emits illumination light with improved uniformity and allows selection of color temperature and a region from which light is emitted. The illumination light from the LED travels in a light guide plate and is reflected off the inner surface to output to the outside through a diffuser plate. A plurality of LEDs differing in hue is provided. An LED driver unit controls a color temperature of light to be emitted, and generates, for example, illumination light of moderate color such as an orange color. The LED driver unit switches between regions from which light is emitted, thus offering unique illumination effects and using the luminaire as an all-night lamp. The light guide plate is secured to the side opposite to the reflector sheet in order to prevent the fixing member from impairing the light uniformity.
