摘要： Methods and systems to provide baseline measurements for aging compensation for a display device are disclosed. An example display system has a plurality of active pixels and a reference pixel. Common input signals are provided to the reference pixel and the plurality of active pixels. The outputs of the reference pixel is measured and compared to the output of the active pixels to determine aging effects. The display system may also be tested applying a first known reference current to a current comparator with a second variable reference current and the output of a device under test such as one of the pixels. The variable reference current is adjusted until the second current and the output of the device under test is equivalent of the first current. The resulting current of the device under test is stored in a look up table for a baseline for aging measurements during the display system operation. The display system may also be tested to determine production flaws by determining anomalies such as short circuits in pixel components such as OLEDs and drive transistors.

摘要： A method of determining the position of an array of sensors, an array of solid-state lamps, or other devices which sense or emit electromagnetic waves includes first determining a sensing or emitting distribution for one of the devices, then integrating that distribution over the area to be covered by the sensors or emitters. In response to the integrated distribution, the sensors or emitters may be repositioned, reconfigured, or reoriented to provide desired coverage. Wireless access points that communicate to wireless end points associated with the lights and/or sensors are designed and positioned to provide adequate signal strength. All elements, light distribution, sensor range, and wireless signal strength may be plotted in contour plots within the same user interface that enables users to place the devices in a specified area.

摘要： A method of detecting a flickering frequency of an ambient light source includes the following steps. First, a light intensity of the light source is sensed in a predetermined time period according to a sampling frequency to obtain a plurality of sample values. Then, the sample values are calculated to obtain a median value. Next, the sample values are binarized according to a result of a comparison between the sample values and the median value to obtain a first sequence. The first sequence is differentiated to obtain a second sequence, and the second sequence includes numbers −1, 0, and 1. Then, a distance between the same numbers in the second sequence is calculated, and the sampling frequency is divided by the distance to obtain the flickering frequency of the ambient light source. A system of detecting a flickering frequency of an ambient light source is also disclosed herein.

摘要： A light emitting element circuit includes a light emitting element (1), a current supply path to the light emitting element (1), a constant current circuit (2) that supplies a current to the light emitting element (1) via the current supply path, and an electric discharge path that discharges an electric charge accumulated at the light emitting element (1) and at a region connected between the both electrodes when the constant current circuit (2) stops a current supply to the light emitting element (1). A light emitting element failure detector (4) that detects a short-circuit of the light emitting element (1) in a light emitting element circuit includes a current instantaneous interruption circuit (5), a voltage detector (60), and a determiner (62). The current instantaneous interruption circuit (5) is arranged on the current supply path different from the electric discharge path and instantaneously interrupts an electric current that the constant current circuit (2) supplies to the light emitting element (1). The voltage detector (60) obtains an output of a voltage Vf between the anode and cathode of the light emitting element (1) during a period of the instantaneous interruption as a measuring object. The determiner (62) determines the existence of a short-circuit from the output.
