Light Detection Means (e.g., With Photodetector) Patents (Class 345/207)
  • Patent number: 10319272
    Abstract: A sensor of a brightness limiting system of a vehicle may sense light from light sources around the vehicle and provide a light measurement signal. The light measurement signal may include information about brightness levels and positions of light sources relative to a window of the vehicle. A brightness controller may monitor the light source measurement signal and perform comparisons of brightness levels from the light measurement signal with brightness thresholds. The brightness controller may determine that a brightness level of a light source exceeds a brightness threshold and may provide a brightness control signal to a brightness control layer positioned adjacent to the window of the vehicle. The brightness control layer may receive the brightness control signal and limit the brightness level of light based on the brightness threshold at a brightness control area of the brightness control layer.

  • Patent number: 10319307
    Abstract: A voltage-programmed display system allows measurement of effects on pixels in a panel that includes both active pixels and reference pixels coupled to a supply line and a programming line. The reference pixels are controlled so that they are not subject to substantial changes due to aging and operating conditions over time. A readout circuit is coupled to the active pixels and the reference pixels for reading at least one of current, voltage or charge from the pixels when they are supplied with known input signals. The readout circuit is subject to changes due to aging and operating conditions over time, but the readout values from the reference pixels are used to adjust the readout values from the active pixels to compensate for the unwanted effects.

  • Patent number: 10079986
    Abstract: A high density, high speed ROIC uses in-pixel integration capacitors and comparators to convert each pixel charge to a train of pulse spikes which increment a capacitor to successive, discrete charge values that represent a digital, non-binary count value of an in-pixel multi-value digital counter (MVDC). The MVDC can include a plurality of stages whereby comparators limit the maximum count of each stage and increment subsequent stages. The maximum count can be a power of two for subsequent direct ADC conversion to binary. The count values and the residual integration capacitor charge can be read out by ramping the comparator reference inputs and measuring the comparator output timings, effectively forming partially in-pixel single-slope ADC's. The comparators can include temporary internal positive feedback to maintain consistency of the spike pulses to better than 10%.

  • Patent number: 10031622
    Abstract: A semiconductor device obtains highly accurate image data regardless of the intensity of incident light. The semiconductor device includes a first photo sensor provided in a pixel, a second photo sensor provided around the pixel, and a controller for setting the drive condition of the first photo sensor in accordance with the intensity of outside light obtained by the second photo sensor. An image is taken after the sensitivity of the first photo sensor is changed in accordance with the drive condition set by the controller. Thus, in the semiconductor device, an image can be taken using the first photo sensor whose sensitivity is optimized in accordance with the intensity of incident light.

  • Patent number: 10008159
    Abstract: An organic electroluminescent display panel and a display apparatus are disclosed. At a first detection phase, aging of the light-emitting device in each sub-pixel is detected one by one. At a display phase, an initial grayscale value for a corresponding sub-pixel is compensated in accordance with the aging of the light-emitting device in each sub-pixel. Moreover, in the display panel the plurality of sub-pixels that belong to the same pixel group share a sense line, such that the number of the wirings in the display panel can be reduced and the number of the signal channels of the driving chip can thus be reduced, leading to a reduced area of the driving chip and a reduced manufacture cost.

  • Patent number: 10003720
    Abstract: Based on a histogram of saturation of an input video, a saturation conversion function is determined, and, referring to the determined saturation conversion function, the saturation of each pixel of the input video is converted. Alternatively, a saturation conversion coefficient determination function is generated from the histogram, a saturation conversion coefficient is determined from the saturation conversion coefficient determination function and the saturation, and color differences are multiplied by the determined saturation conversion coefficient. Regardless of what saturation distribution the input video has, the saturation can be properly enhanced, and at the same time a high gradation expression can be obtained.
