Abstract: PROBLEM TO BE SOLVED: To allow quick and accurate correction of image sticking. SOLUTION: In a display device, the reduction in brightness due to aging degradation is corrected on the basis of emission brightness of respective pixels 101 measured by light receiving sensors provided on a rear surface of an EL panel 2. A reflecting sheet 61 is bonded to and disposed on a surface opposite to a surface whereon a gate electrode 73 is formed, of a support substrate 71 constituting the EL panel, namely, on the rear surface of the EL panel 2. Thus light emitted from an organic EL layer 79, which is shown by an optical path Xd, is repeatedly reflected by the reflecting sheet 61 and metal films such as auxiliary wiring 81 and an anode electrode 78 to reach the light receiving sensors provided in places distant from pixels 101 emitting the light. This technology is applicable to, for example, a panel using spontaneous light emitting elements. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a display device capable of performing a highly precise image persistence correction at high speed. SOLUTION: Based on the luminance of light emitted by each pixel, measured by a light-receiving sensor 3 provided on the back of an EL panel 2, a display device corrects a luminance decrease caused by deterioration resulting from a lapse of time. A space for the passage of light emitted from an organic EL layer 79, reflected to a counter substrate 72, and entering the back surface of the EL panel 2 is obtained between adjacent anode electrodes 78. Thus, light emitted from the organic EL layer 79 defined by optical paths Xb' and Xc' and reflected by the counter substrate 72 is caused to reach the light-receiving sensor 3. The present invention can be applied to a panel using an element that emits light by itself. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting device capable of improving the viewing angle, while restraining degradation of front-surface luminance. SOLUTION: A light control film 50, formed by stacking a plurality of scattering layers 51, is arranged on a surface of a sealing panel 20. The respective scattering layers 51 has a fixed refraction indexes in the thickness direction, and has a distribution of the refraction indexes in an in-plane specific direction. Tilt angles of the scattering layers 51 are smaller than the critical angle, and the tilt angles thereof are different from one another. As a result, viewing angle characteristics are improved, while restraining degradation of front-surface luminance. In the stacking state of the respective scattering layers 51, it is preferable that they be stacked, such that the tilt angles will increase sequentially, as they approach the upper layer side from the side close to the light-emitting layer. Irregularities can be offset or reduced, by preventing the generation of the positive tilt in the luminance-view angle characteristics (curve) on a light extraction surface 40, generated by the light distribution characteristics of the incident light from the light-emitting layer.

Abstract: PROBLEM TO BE SOLVED: To provide a display device capable of correcting variance in color tone appearing by panels. SOLUTION: The display device includes a color correcting circuit 5 which corrects colors of an externally input RGB video signal and then outputs the RGB video signal to a panel 1.

Further, the color correcting circuit 5 finds a second conversion matrix for converting XYZ chromaticity of a saturation color previously set depending upon specifications of the panel into RGB chromaticity, and then converts the input RGB video signal into an output RGB video signal by using those first and second conversion matrixes to correct variances in saturation color and white appearing by panels according to specifications of the panels.
