摘要： An electronic paper having a display unit formed of a flexible sheet. The electronic paper comprises the display unit composed of a light-emitting device and a switching device and a drive unit composed of a drive circuit disposed at one edge of the display unit. The light-emitting device and the switching device both operate at low operating frequencies and are made of a flexible organic semiconductor. Since the hardness of the drive unit can be high, a semiconductor device having a high operating frequency such as a C-MOS is provided to the drive unit. Though the switching time is relatively long, the data setting time can be short. As a result, a sharp image can be produced.

摘要： An organic semiconductor film that can be used for an electron device, for example, particularly can be used for organic TFTs so as to allow the TFTs to have advanced performance, is provided and a manufacturing method therefor is provided. For instance, the organic semiconductor film contains the organic conductive high polymer compound such as polythiophene represented by the below formula (I). The organic semiconductor film is formed by forming a solution in a thin film form, the solution showing two or more spectral peaks (spectral state B) in a wavelength region of 300 to 800 nm by measurement using a visible and ultraviolet absorption spectral method; and drying the solution formed in the thin film form. Alternatively, the organic semiconductor film can be formed by the method in which the organic conductive high polymer compound has a molecular weight distribution range Mw/Mn from 1.00 to 1.85, obtained by dividing a weight-average molecular weight Mw by a number-average molecular weight Mn. With these methods, principal chains of the organic conductive high polymer compound molecules are arranged substantially in parallel, thus enhancing carrier mobility.

摘要： A method of manufacturing an organic electroluminescence display includes preparing a substrate including pixels. The pixels each include a drive transistor and a capacitor. The capacitor of a subject pixel is caused to hold a voltage which corresponds to a threshold voltage of the drive transistor, and the voltage is read. A first signal voltage is obtained by adding a first correction parameter of the subject pixel to a second signal voltage corresponding to a single gradation level belonging to an intermediate gradation region or a high gradation region of representative voltage-luminance characteristics. The first signal voltage is applied to the driver of the subject pixel, and a luminance emitted by the subject pixel is measured. A second correction parameter with which the luminance emitted by the subject pixel becomes a standard luminance is calculated.

摘要： A display device includes a luminescence element. A power line provides the luminescence element with an electric current. A capacitor accumulates a driving voltage corresponding to a data voltage. A driver flows the electric current according to the driving voltage accumulated in the capacitor through the luminescence element via the power line. A controller is configured to set a reverse bias voltage and an application time period according to an amount of luminescence produced by the luminescence element, and to determine luminance levels in luminescence periods. The controller sets the reverse bias voltage and the application time period according to a peak luminance of the luminance levels when a difference between the peak luminance and an average luminance of the luminance levels exceeds a predetermined threshold, and applies the reverse bias voltage for the application time period within an OFF period of the data voltage for removing an electric charge accumulated in the luminescence element. The OFF period is within one of the luminescence periods.
