摘要： To provide a light emitting device without nonuniformity of luminance, a correcting circuit for correcting a video signal supplied to each pixel to a light emitting device. The correcting circuit is stored with data of a dispersion of a characteristic of a driving TFT among pixels and data of a change over time of luminance of a light emitting element. Further, by correcting a video signal inputted to the light emitting device in conformity with a characteristic of the driving TFT of each pixel and a degree of a deterioration of the light emitting element based on the over-described two data, nonuniformity of luminance caused by a deterioration of an electroluminescent layer and nonuniformity of luminance caused by dispersion of a characteristic of the driving TFT are restrained.

摘要： The brightness of a light emitting element varies when changes in ambient temperature or changes with time occur. In view of this, the invention provides a display device where the influence of variations in the current value of the light emitting element due to changes in ambient temperature and changes with time can be suppressed. The display device of the invention includes a monitoring element that is driven with a constant current, and a voltage applied to the monitoring element is detected and inputted to a light emitting element. In other words, the monitoring element is driven with a low current, and a voltage applied to the monitoring element is inputted to the light emitting element such that the light emitting element is driven with a constant current.
摘要翻译： 随着环境温度的变化或时间的变化，发光元件的亮度发生变化。 鉴于此，本发明提供了一种显示装置，其中可以抑制由于环境温度的变化和随时间的变化而导致的发光元件的电流值的变化的影响。 本发明的显示装置包括以恒定电流驱动的监视元件，并且检测施加到监视元件的电压并将其输入到发光元件。 换句话说，监视元件以低电流驱动，并且施加到监视元件的电压被输入到发光元件，使得发光元件以恒定电流驱动。
