摘要： An object is to provide a photoelectric conversion device which can correct a difference between a measured light intensity and an actual light intensity, which occurs when output current decreases due to the fact that a strong light is received, and outputs the corrected current. The photoelectric conversion device includes a photoelectric conversion element; a photocurrent output circuit for providing a first current corresponding to the amount of incident light on the photoelectric conversion element; a photocurrent correcting circuit which includes a corrective photoelectric conversion element for providing a second current, the corrective photoelectric conversion element including a light shield film for blocking part of light; a photocurrent adder circuit which includes a circuit for providing a fourth current; and an amplifier circuit including a circuit which amplifies a current corresponding to the sum of the first current and the fourth current and outputs the amplified current.

摘要： Outside light is received using a light sensor, and in accordance with the outside light intensity, each of a first display mode which expresses multiple gray scales and a second display-y mode which expresses a gray scale smaller in number than that in the first display mode is switched and used. The switching is controlled by a display controller based on data of the outside light intensity. Accordingly, the visibility can be ensured in a wide range of situations, from under a fluorescent lamp in a dark place or inside, to under sunlight outside. In the second display mode, frequencies of a start pulse and a clock pulse to be inputted to a source signal line driver circuit are reduced and a driving voltage is decreased by the display controller; accordingly, a frame period can be longer than that in the first display mode and power consumption can be reduced.
