Method of inspecting defect for electroluminescence display apparatus, defect inspection apparatus, and method of manufacturing electroluminescence display apparatus using defect inspection method and apparatus

A dark spot defect caused by short-circuiting of an EL element is detected based on an emission brightness or a current flowing through the EL element when an element driving transistor which controls a drive current to be supplied to the EL element is operated in its linear operating region and the EL element is set to an emission level. A dim spot defect caused by a characteristic variation of the element driving transistor can be detected based on a current flowing through the EL element when the element driving transistor is operated in its saturation operating region and the EL element is set to the emission level. When an abnormal display pixel is detected based on an emission brightness, a pixel which is determined as an abnormal display pixel and which is not determined as a dark spot defect during a dark spot inspection is determined, and the pixel is detected as a dim spot defect caused by the characteristic variation of the element driving transistor.

Light emitting element and method for producing the same

A light scattering section is formed on at least part of a surface of a sealing resin section including fluorescent bodies and covering light emitting diode chips. Light from the light emitting diode chips is scattered by the light scattering section, and then is returned to the sealing resin section so as to excite the fluorescent bodies so that fluorescence is generated. Part of the light to be emitted outside a light emitting element from the light emitting diode chips returns to the sealing resin section so that chromaticity of the light is converted by the fluorescent bodies, thereby adjusting a chromaticity variation among the light emitting elements. In this way, the chromaticity variation among the light emitting elements can be adjusted.

In a method of manufacturing a display apparatus, an opposite substrate on which a conductive pattern is formed is coupled with a display substrate to face the display substrate, and the opposite substrate is cut to partially expose the display substrate. Since the conductive pattern is cut with the opposite substrate during the cutting of the opposite substrate, an electric resistance of the conductive pattern is changed. The change in electric resistance of the conductive pattern is detected to determine whether the opposite substrate is cut or not.

Display device, and methods for manufacturing and controlling the display device

A display device corrects uneven luminance due to uneven element characteristics by simple measurement and correction with a low cost. The display device includes pixels that each include a light emitter and a driver. Data lines supply a voltage signal to the driver of each pixel. A data line driver supplies the voltage signal to each data line. A first memory stores, for each pixel, a luminance gain for adjusting a luminance corresponding to a video signal to a standard luminance. A second memory stores conversion curve information representing a representative conversion curve common to the pixels. A corrector converts, for each pixel, the luminance into a corresponding standard luminance value based on a corresponding luminance gain stored in the first memory, while a converter converts, for each pixel, the corresponding standard luminance into a corresponding voltage signal based on the conversion information stored in the second memory.
