A problem in that a light emitting element slightly emits light is solved by an off current of a thin film transistor connected in series to the light emitting element, thereby a display device which can perform a clear display by increasing contrast, and a driving method thereof are provided. When the thin film transistor connected in series to the light emitting element is turned off, a charge held in the capacitance of the light emitting element itself is discharged. Even when an off current is generated at the thin film transistor connected in series to the light emitting element, this off current charges this capacitance until the capacitance of the light emitting element itself holds a predetermined voltage again. Accordingly, the off current of the thin film transistor does not contribute to light emission. In this manner, a slight light emission of the light emitting element can be reduced.

A semiconductor element is operated without being affected even when the substrate is largely affected by heat shrink such as a large substrate. Furthermore, a thin film semiconductor circuit and a thin film semiconductor device each having the semiconductor element. Also, a semiconductor element is operated without being affected even if there is slight mask deviation. In view of them, a plurality of gate electrodes formed so as to overlap a lower concentration impurity region of a semiconductor layer than drain regions on a drain region side. Also, source regions and the drain regions corresponding to the respective gate electrodes are formed so that current flows in opposite directions each other through channel regions corresponding to the gate electrodes. Further, the number of the channel regions in which a current flows in a first direction is equal to the number of the channel regions in which a current flows in a direction opposite to the first direction.

A printing apparatus and a print control method which detect a defective printing element in operation failure status while reciprocate-scanning a printhead, and perform appropriate print control such as complementary printing on an unprinted portion by the defective printing element, without reducing the printing speed. An apparatus, to which the method is applied, has a photosensor 8, to detect ink discharge statuses of a plurality of nozzles of a printhead 5, which is provided between a home position of the printhead and the outside of an effective printing area where image printing is to be made. While the printhead 5 is scanned, test ink discharge is performed at the position of the photosensor 8, and the ink discharge statuses of the nozzles are detected by the photosensor 8. A corrector 123 analyzes the operation statuses of the nozzles of the printhead 5 based on the results of detection in a real time manner. A CPU 25 performs print control based on the results of analysis.

The invention provides an image forming method and apparatus capable of forming an image with a desired shape at a correct position on a recording medium having expansion and contraction properties. Boundary lines formed on the recording medium being conveyed are detected by a sensor. Distortion of the recording medium is evaluated on the basis of the detected boundary lines. Image data is corrected in accordance with the result of the evaluation and an image is formed in accordance with the corrected image data. In the above process, image data within the respective areas surrounded by the boundary lines is deformed such that the image is printed at a correct location even when the recording medium has distortion due to expansion/contraction.

An ink jet printing apparatus has a station for dyeing a thread for embroidering by discharging ink onto the thread from an ink jet head. According to one aspect of the invention, a printing controller controls the amount of ink discharged per unit time onto the thread according to the speed of relative movement of the thread and the ink jet head. Another aspect of the invention accounts for the length of non-usable thread per unit time between an ink jet printing unit and the tip of an embroidery needle in an embroidery machine.
