A color and infrared image sensor includes a silicon substrate, MOS transistors formed in the substrate and on the substrate, first photodiodes at least partly formed in the substrate, a photosensitive layer covering the substrate, and color filters, the photosensitive layer being interposed between the substrate and the color filters. The image sensor further includes first and second electrodes on either side of the photosensitive layer and delimiting second photodiodes in the photosensitive layer, the first photodiodes being configured to absorb the electromagnetic waves of the visible spectrum and of a first portion of the infrared spectrum and the photosensitive layer being configured to absorb the electromagnetic waves of the visible spectrum and to give way to the electromagnetic waves of said first portion of the infrared spectrum.

Color and infrared image sensor

An image acquisition device includes a single sensor having organic photodetectors, an angular filter, and a color filter. The color filter has one or a plurality of first portions adapted to give way to at least one wavelength in the visible range, and one or a plurality of second portions filtering wavelengths outside of red and/or near infrared. The second portion has a surface area approximately equal to a surface area of one of the photodetectors or a surface area greater than or equal to the surface area of four of the photodetectors.

Image acquisition device

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.

Device integrating an image sensor and a display screen

An image sensor includes organic photodetectors and an angular filter less than 20 &#x3bc;m away from the photodetectors. Further, a method of manufacturing an image sensor includes the forming of organic photodetectors and of an angular filter less than 20 &#x3bc;m away from the photodetectors.

Image sensor comprising an angular filter

An image sensor includes an array of readout circuits in non-organic technology and photodiodes made of organic materials.

Image sensor

A color and infrared image sensor includes a silicon substrate, MOS transistors formed in the substrate, a stack covering the substrate and including a first photosensitive layer, an electrically-insulating layer, a second photosensitive layer, and color filters. The image sensor further includes electrodes on either side of the first photosensitive layer and delimiting first photodiodes, and electrodes on either side of the second photosensitive layer and delimiting second photodiodes. The first photosensitive layer absorbs the electromagnetic waves of the visible spectrum and of a portion of the infrared spectrum and the second photosensitive layer absorbs the electromagnetic waves of the visible spectrum and gives way to the electromagnetic waves of the portion of the infrared spectrum.

A device for detecting an electromagnetic radiation has at least one photodetector including an organic diode and an organic photodiode formed in a same stack of semiconductor layers, the organic photodiode receiving the radiation. The photodetector further includes at least one screen which is opaque to the radiation and screens the portion of the stack corresponding to the diode.

Radiation detection device comprising organic photodiodes

A display system including a display screen having first and second display sub-pixels where each first display sub-pixel includes a first light-emitting component emitting a first radiation and covered with a first colored filter and first conductive tracks and where each second display sub-pixel includes a second light-emitting component emitting a second radiation and covered with a second colored filter and second conductive tracks. The display system further includes an image sensor detecting the first or second radiation or a third radiation. The first display sub-pixels include first elements absorbing the first radiation and the second radiation and covering the first conductive tracks. The first absorbing elements and/or the first colored filter delimit a first passageway along the stacking direction for the first, second, or third radiation.

Display system comprising an image sensor

An image acquisition system includes a source of a radiation, an image sensor including an array of photodetectors capable of detecting the radiation and including a surface, and an angular filter, covering the sensor, and capable of blocking the rays of the radiation having an incidence relative to a direction orthogonal to the surface greater than a threshold and of giving way to at least certain rays of the radiation having an incidence relative to a direction orthogonal to the surface smaller than the threshold.

Image acquisition system

A display and detection system including an image sensor, a display screen and an antireflection system covering the display screen and the image sensor, such an antireflection system including an electrically-controllable rectilinear polarizer.
