    摘要： Provided is an image display device in which deterioration of a self-light-emitting element within a pixel is corrected accurately. A detection unit detects, within a detection period, a difference in characteristics between self-light-emitting elements of adjacent pixels. A first subtraction circuit outputs a differential voltage between a reference voltage and an image voltage to a self-light-emitting element that is determined by the detection unit as a deteriorated element. An amplifier amplifies an output of the first subtraction circuit with a gain [1/{1-(α/100)}]1/2 when a driver transistor is driven in a saturation region. The amplifier amplifies the output of the first subtraction circuit with a gain [1/{1-(α/100)}] when the driver transistor is driven in a linear region. A differential between the reference voltage and an output of the amplifier obtained by a second subtraction circuit is used as a corrected image voltage.

    摘要： An image display device comprises a unit which divides one line into a plurality of blocks (blocks A, B, and C) in a horizontal direction and detects in parallel, a unit which collectively detects a plurality of lines (lines A and B) in a vertical direction in parallel. The unit detects a pixel state of a pixel of the block (for example, block A) and a pixel state of the same pixel as an adjacent block (for example, block B), and corrects a variation between the detection result of the block and the detection result of the adjacent block. The unit detects a pixel state of a pixel through the line (for example, line A) and a pixel state of the same pixel through a different line (for example, line B), and corrects a variation between the detection result of the line and the detection result of the different line.

    摘要： An image display with high brightness where a long time can be secured for light emission of self-luminous elements can be implemented using only line memories.The period for the writing in of a display voltage (period for writing in of data) continues for a number of lines (three lines), and the reset pulse becomes of a “high” state. Subsequently, operation for three lines is carried out collectively during a triangular wave period (period for writing in of a triangular wave voltage), and only the light emission controlling pulse becomes of a “high” state. During the period for the writing in of a triangular wave voltage, the writing in of a triangular wave voltage from the second time onward is rewriting of a triangular wave voltage, and thus, the period for rewriting the display voltage (dotted line portion) becomes unnecessary, and a longer period for light emission, where the light emission controlling pulse becomes of a “high” state, can be secured.
