A light beam from a to-be-tested display panel is split by a beam-splitting assembly into at least two testing light beams. A voltage value corresponding to a first testing light beam is measured by a trans-impedance amplification circuit corresponding to a first optical sensor. Next, an integration time period is determined by a control circuit according to voltage values from the trans-impedance amplification circuit and a predetermined relational model between voltage values corresponding to the light intensities and integration time periods. A voltage value corresponding to a second testing light beam is finely measured by the integration circuit corresponding to a second optical sensor within the integration time period. Finally, the display brightness value of the to-be-tested display panel is determined by the control circuit according to a voltage value from the integration circuit within the integration time period.

Abstract: One embodiment of the disclosure includes an A-D conversion circuit connected to a photodiode for providing a silicon photomultiplier that with enhanced detection accuracy and a time resolution. A current generated upon photon detection by the photodiode partially flows into another photodiode adjacent to the photodiode arranged in parallel via a resistor. At this time, the current is charged into a parasitic capacitance adjacent to the photodiode, and thereafter is discharged. However, the discharged current cannot flow toward an output terminal by the A-D conversion circuit, and also cannot switch the A-D conversion circuit. Consequently, the construction of the disclosure can detect light with no influence of the current discharged from the parasitic capacitance. As a result, the disclosure achieves a silicon photomultiplier with high detection accuracy and a satisfactory time resolution.

Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference. Thus, these measurements can be performed substantially simultaneously with minimal interference from each other. The pulse oximetry measurement system correlates the measured light intensities using pseudo-random noise generation and phase division multiplexing, and computes the measured and correlated peak-to-peak detected light amplitudes to obtain a ratio between these light amplitudes for determining oxygen saturation in the blood, and may also be used for heart rate monitoring.
