With an image sensor in which the amplifier circuit is disposed at each pixel, there is such an issue that the threshold voltage of the transistor fluctuates so that the signal voltage fluctuates because a voltage is continuously applied between the source and the gate of the transistor at all times when using the amorphous thin film semiconductor as the transistor that constitutes an amplifier circuit. The gate-source potential of the TFT that constitutes the amplifier circuit is controlled so that the gate terminal voltage becomes smaller than the source terminal voltage in an integrating period where the pixels accumulate the signals, and controlled so that the gate terminal voltage becomes larger than the source terminal voltage in a readout period where the pixels output the signals.


An example of display apparatus includes: a display panel in which unit pixels each constituted by at least a first subpixel displaying a first pattern and a second subpixel displaying a second pattern are alternately arranged in a row or column direction; and a signal processing unit modulating, for image data including the first pattern and image data including the second pattern, a difference in maximum gradation values in the image data, and controlling synchronization or non-synchronization of a rise or fall between bit signals of a coupled image signal input to the display panel.

A liquid crystal display apparatus comprises a planar first electrode, multiple second electrodes and third electrodes that overlap with the first electrode and are alternately arranged, in correspondence to one subpixel. The second electrode and the third electrode are independently driven. A voltage for driving the liquid crystal is individually applied between the second electrode and the first electrode and between the third electrode and the first electrode.

A TFT biosensor includes a gate electrode (silicon substrate), a reference electrode, and enzyme that is fixed to an insulating substrate spatially separated from the gate electrode and the reference electrode. A pH variation in the vicinity of an ion-sensitive insulating film is induced by a reaction between the enzyme and a sensing object material. The TFT biosensor can detect a concentration of the sensing object material with high sensitivity by detecting the pH variation as a threshold voltage shift of characteristics of a gate-source voltage to a source-drain current.
