Abstract: A matrix-array detector having: an array of pixels arranged in a matrix along rows and down columns, each pixel for generating a signal according to a physical effect; a signal generator for generating two clock signals that are phase-shifted relative to one another; and a row-addressing device including a shift register, the shift register including a plurality of stages arranged in a cascade, each stage for receiving, in alternation from one stage to another, one clock signal from the two clock signals, and delivering an intermediate output signal that takes a high value and a low value allowing the pixels of the row to be activated and to be deactivated, respectively. The signal generator is also for generating a third clock signal.

Abstract: A device includes a display screen and an image sensor. A first electromagnetic shielding layer permeable to light is arranged between active portions of the display screen and active portions of the image sensor.

Abstract: An electro-optical device for a matrix image sensor, has thin-film transistors and organic detectors, which integrates a line driver circuit, with thin-film transistors in a peripheral area. A light screen is provided on a topological level supported by a dielectric layer above the thin-film transistors, which are individual screens, for each pixel in a matrix area, and a general screen for all the transistors of the driver circuit. The general screen in the peripheral area is further used as an interconnection structure to bias an upper electrode of the organic photodiodes of an active area to a bias voltage, by an overlapping in direct contact. In the active area, a topological level of the upper electrode is separated from the topological level of a pixel electrode by an active organic structure. In the peripheral area, these two topological levels are present and formed directly on each other, with no interposition.

Abstract: Testing of control wires of a pixel array of an image sensor is performed by applying a signal transition to a control wire and detecting, based on a voltage signal detected on the control wire, the duration of at least part of the signal transition on the control wire. An electrical fault in the control wire is indicated based on a comparison of the detected duration to a threshold.
