    摘要: The present invention aims to provide a method for driving an electro-optical device, an electro-optical device and electronic equipment that can solve the insufficient supply of the data current and current fluctuation. A data current (Imax) is applied to a plurality of pixels (20) provided to a display panel unit with same value through the data line (Xm) regardless of grayscale data. Upon supply of the data current (Imax), in the pixel (20), a transistor selected in reproduction Trep is turned on such that a drive current (Idr) corresponding to the data current (Imax) output from a driving transistor (Tdr) is supplied to an organic EL element (21), thereby emitting light. A light-off signal (Vsig) is supplied to the pixel (20) at predetermined timing such that the organic EL element (21) emits light only in the light-emitting period computed based on the grayscale data. The pixel (20) to which a constant data current is supplied emits light at a luminance corresponding to the grayscale data by changing the light-emitting period corresponding to the grayscale data.

    摘要: A transistor circuit (100) including a driving transistor (110) where conductance between a source and a drain is controlled in response to voltage, and a compensating transistor (120) where a gate is connected to one of a source and a drain and wherein the compensating transistor is connected so as to supply input signals to the gate of the driving transistor through the source and drain. In a transistor circuit where conductance control in a driving transistor is carried out in response to the voltage of input signals, it is possible to control the conductance by using input signals of a relatively low voltage and a variance in threshold characteristics of driving transistors is compensated. With this transistor circuit, a display panel that can display picture images with reduced uneven brightness is achieved.

    摘要: The invention provides a method and apparatus to obtain accurate gradation by obtaining an accurate ratio of light emitting parts in a display device which implements gradation by forming a plurality of TFTs and a plurality of OELDs in each pixel, interconnecting the TFTs and OELDs, and switching an on and off state of the TFTs, and controlling a light emitting area of the OELDs. A plurality of OELDs have the same shape, and gradation can be implemented by controlling the number of OELDs that emit light at a given time. Preferably a plurality of OELDs have a round shape. Also preferably plurality of OELDs are ranged at the same interval in a vertical and/or horizontal direction. According to this structure, because the light emitting areas of the plurality of OELDs become equal to each other, by controlling the number of OELDs, a ratio of the light emitting areas can be accurately obtained.
