    Abstract: A pixel circuit, display device, and method of driving a pixel circuit enabling source-follower output with no deterioration of luminance even with a change of the current-voltage characteristic of the light emitting element along with elapse, enabling a source-follower circuit of n-channel transistors, and able to use an n-channel transistor as an EL drive transistor while using current anode-cathode electrodes. The circuit includes a source of a TFT used as a drive transistor that is connected to an anode of a light emitting element, and a drain of the TFT is connected to a power source potential. A capacitor is connected between a gate and source of the TFT, and a source potential of the TFT is connected to a fixed potential through a TFT used as a switching transistor.

    Abstract: An information processing device includes an image acquirer that acquires a shot image of a user, a registered user information holder that holds face identification data of a registered user, and a face authentication section that detects a face image of a registered user existing in the shot image by using face identification data held in the registered user information holder. The information processing device further includes an information processing section that executes information processing based on a detection result by the face authentication section, and a face identification data registration section that updates the face identification data based on a face image extracted from a shot image of a user at predetermined timings. The face identification data registration section determines whether or not to update the face identification data with a condition corresponding to a situation in which the timing is generated.

    Abstract: A pixel circuit able to prevent a spread of the terminal voltages of drive transistors inside a panel and in turn able to reliably prevent deterioration of uniformity, wherein a source of a TFT serving as a drive transistor is connected to an anode of a light emitting element, a drain is connected to a power source potential, a capacitor is connected between a gate and source of the TFT, and a source potential of the TFT is connected to a fixed potential through a TFT serving as a switch transistor and wherein pixel circuit lines are connected by an upper line and bottom line and are arranged in parallel with pixel circuit power source voltage lines so as not to have intersecting parts.
