Description
Technical Field
The present application relates to the field of optoelectronics, and in particular, to an image sensor, an imaging device, and an electronic apparatus.
Background
A common imaging device includes an image sensor and a lens. An image sensor generally includes a pixel array, which is formed by arranging a plurality of pixel units in a matrix array, and is capable of receiving an optical signal and generating an electrical signal. An image sensor converts an optical signal into an electrical signal, which needs to pass through an analog-to-digital conversion module, but due to the limitation of the analog-to-digital conversion precision, a small voltage value cannot be converted, dark details in an image cannot be displayed, and in order to retain the dark details in the image, an image sensor manufacturer adds a fixed offset, namely a black level, to the voltage before the analog-to-digital conversion input. In addition, ideally, the electrical signal generated by the pixel unit can accurately represent the received light signal energy, and actually, due to circuit noise interference, the pixel unit generates a dark current even when the light signal is not received. Dark current is related to exposure time and circuit gain, and the magnitude of dark current varies from pixel cell to pixel cell. Therefore, the black level calibration is performed before the image data is processed. Typically, some of the pixel cells at the periphery of the pixel array will be set as black pixels for providing a black level. However, since these black pixels are not used for actual imaging but occupy the position of the pixel array, the pixel unit of the image sensor has a low utilization rate and the imaging resolution is low.

Fig. 5 is a partial cross-sectional view of the first pixel unit 16. The first pixel unit 16 includes a photosensitive layer 164, a dimming layer 163, a filter layer 162, and a lens layer 161 sequentially arranged from bottom to top. The photosensitive layer 164 may include a photoelectric conversion device, for example, but not limited to, the photosensitive layer 164 may include a photodiode (Photo Diode). The photosensitive layer 164 receives the imaging light beam 101 and converts photons into electrons, thereby generating an electrical image signal.

The filter layer 162 is located below the lens layer 161, and is configured to transmit a light beam in a target wavelength band and filter a light beam outside the target wavelength band, where a wavelength of the imaging light beam 101 is within the target wavelength band. The filter layer 162 illustrated in fig. 5 is located between the lens layer 161 and the light modulation layer 163.

It is to be understood that the first transmittance should be as small as possible, for example, close to or equal to 0.

As such, when the dimming layer 163 has a first transmittance, the first pixel unit 16 may function as a black pixel unit for generating a black level signal; when the dimming layer 163 has the second transmittance, the first pixel unit 16 may serve as an imaging pixel for receiving the imaging light beam 101 and generating an image electric signal.
Fig. 6 is a partial cross-sectional view of the light modulation layer 163 shown in fig. 5. The dimming layer 163 may include a second substrate 1635, a second conductive layer 1634, an electrochromic layer 1633, a first conductive layer 1632, and a first substrate 1631 stacked in sequence from bottom to top. The first substrate 1631 and the second substrate 1635 may be made of glass, a transparent polymer material, or any other suitable transparent material. The first conductive layer 1632 and the second conductive layer 1634 may be Indium Tin Oxide (ITO) semiconductor transparent conductive films. When the first conductive layer 1632 and the second conductive layer 1634 are energized (i.e., under the action of an applied electric field), the electrochromic layer 1633 is electrically colored, and at this time, the transmittance of the electrochromic layer 1633 to the imaging light beam 101 is small. When the first conductive layer 1632 and the second conductive layer 1634 are powered off (i.e., no electric field is applied), the electrochromic layer 1633 is electrically discolored, and at this time, the transmittance of the electrochromic layer 1633 to the imaging light beam 101 is relatively high. Optionally, in some embodiments, when the electrochromic layer 1633 is powered on, the transmittance of the light modulation layer 163 for the imaging light beam 101 is the first transmittance; when the electrochromic layer 1633 is not energized, the transmittance of the light modulation layer 163 for the imaging light beam 101 is the second transmittance.
It is understood that, since the first substrate 1631, the first conductive layer 1632, the second conductive layer 1634 and the second substrate 1635 are made of transparent materials, the first substrate 1631, the first conductive layer 1632, the second conductive layer 1634 and the second substrate 1635 can be considered to have high transmittance (e.g., greater than or equal to 95%) for the imaging light beam 101. Thus, the transmittance of the electrochromic layer 1633 with respect to the imaging light beam 101 determines the transmittance of the dimming layer 163 with respect to the imaging light beam 101.
The electrochromic layer 1633 includes an electrochromic material whose absorption wavelength can produce a reversible change in color under the action of an applied electric field. The electrochromic material may be structurally classified into an inorganic electrochromic material and an organic electrochromic material. The inorganic color-changing material may be, for example, but not limited to: transition metal oxides, such as tungsten oxide, molybdenum oxide, nickel oxide, cobalt oxide, cause the valence state change of metal ions under different voltages due to ion and electron injection, thereby realizing the appearance of a specific color (e.g., black) under the action of an electric field and the restoration of transparency under the action of no electric field. Organic electrochromic materials can be classified into small molecule color-changing materials and high molecule color-changing materials, such as but not limited to conducting polymers, such as polyaniline, polythiophene, polypyrrole, PEDOT, and the like, which can take on red, blue, purple, and the like colors when an electric field is applied. Of course, the embodiment of the present application is not limited to the specific structure and material of the electrochromic layer 1633, and any optical film layer with different transmittance to the imaging light beam 101 when an electric field is applied and not applied is within the scope of the present application.
In summary, the image sensor 11 includes the pixel array 12, the pixel array 12 includes the first pixel unit 16, and the first pixel unit 16 includes a light modulation layer 163, which can be used to adjust the transmittance of the imaging light beam 101, so as to selectively control the first pixel unit to generate a black level signal or receive the imaging light beam and generate an image electrical signal. Accordingly, the first pixel unit 16 of the image sensor 11 of the present application can be multiplexed into a black pixel unit and an imaging unit for generating a black level signal and an image electric signal. Compared with the prior art, the image sensor 11, the imaging device 10 and the electronic device 1 have more pixel units which can be used for generating image electric signals, so that the image sensor has higher pixel utilization rate and higher imaging resolution.
