摘要： An active matrix type EL display device is provided, which is capable of suppressing the unevenness of luminance display due to the unevenness of the characteristics of TFTs which constitute pixels, or due to variations in the environmental temperature at which the display device is used. The active matrix type EL display is driven by a time gray scale method, and is capable of keeping the drain current of each of its EL driving TFTs constant by operating each of the EL driving TFTs in a saturation region in an ON state. Accordingly, constant current can be made to flow in each of the EL elements, whereby it is possible to provide an active matrix type EL display device with accurate gray scale display and high image quality.

摘要： A counter 102 counts the accumulated lighting time or the accumulated lighting time and the intensity of lighting of each pixel by a first image signal 101A and stores them in a volatile memory 103 or a nonvolatile memory 104. A correction circuit 105 corrects the first image signal based on the correction data stored previously in a correction data storage section 106 in accordance with the degree of the degradation of each spontaneous light emitting element by the use of the accumulated lighting time or the accumulated lighting time and the intensity of lighting, and produces a second mage signal 101B. By the second image signal 101B, a display unit 107 can provide a uniform screen having no variation in luminance even if the light emitting elements in a part of the pixels are degraded.

摘要： A voltage equal to the threshold value of a TFT (106) is held in capacitor unit (109). When a video signal is inputted from a source signal line, the voltage held in the capacitor unit is added thereto and a resultant signal is applied to a gate electrode of the TFT (106). Even when a threshold value is varied for each pixel, each threshold value is held in the capacitor unit (109) for each pixel. Thus, the influence of a variation in threshold value can be eliminated. Further, holding of the threshold value is conducted by only the capacitor unit (109) and a charge does not move at writing of a video signal so that a voltage between both electrodes is not changed. Thus, it is not influenced by a variation in capacitance value.
