    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a light-to-frequency sensor conversion. In some implementations, a first output waveform is generated from a light signal, a frequency of the first output waveform being based on an intensity of the light signal, including integrating the light signal across multiple clock cycles. In response to receiving a notification, a hold operation is performed to stop integrating the light signal for a period of time. In response to an end of the hold operation, a second output waveform is generated that includes integrating the intensity of the light signal starting from the end of the hold operation over a count of the multiple clock cycles that start after the end of the hold operation by a delay amount. The first output waveform and the second output waveform are summed to determine the intensity of the light signal.

    Abstract: Provided are a display panel and a display apparatus; the display panel comprises at least one sensing module (100) arranged in a peripheral area (B), the sensing module (100) comprises at least one sensing unit, the sensing unit (101, 102, 103) comprises a sensing transistor, a first end of the sensing transistor receives an electrical signal, a gate of the sensing transistor receives a first control signal, and a second end of the sensing transistor outputs a photosensitive signal. When the sensing transistor receives the first control signal, a gate of the sensing transistor is set to be in a closed state; when the sensing transistor is illuminated, the voltage outputted by a drain electrode of the sensing transistor increases, the voltage change amount is read as the photosensitive signal, and ambient light is identified according to the spectral features of common ambient light in combination with the response results of different wavelengths. On the basis of that functionality, the display color temperature can be optimized and display performance is improved.

    Abstract: Aspects of the present disclosure relate generally to night-vision systems and more specifically to an integrated micro-display module with a flex circuit. One example illustrated herein includes a method of upgrading a night-vision system. The method may include attaching a flex circuit to an intensifier module, in which the flex circuit includes one or more light detectors and extending beyond a leading edge of the intensifier module. The method may include inserting the intensifier module into a housing and folding the flex circuit to expose the one or more light detectors. The method may further include optically coupling a display unit to an output side of an intensifier module of the night vision system. The display unit may be configured to display graphical content in a field of view together with night-vision images from an output of the intensifier module of the night-vision system.
