In at least one example embodiment, the LED driver circuit includes a first switching element, a second switching element, a sense resistor, a sensing unit, a calculator, and a driver. The plurality of LEDs, the first switching element, the second switching element, and the sense resistor are coupled to each other in series in this order. The sensing unit receives a voltage at a node between the second switching element and the sense resistor, and generates voltage data representing the voltage. The calculator calculates a temporal average of a current flowing through the LEDs based on the voltage data, and generates current data corresponding to the temporal average. The driver drives the first switching element and the second switching element based on the current data.

摘要： An illumination device includes an LED package, an LED driver including an FET, and a thermistor disposed on a substrate. A plurality of such LED packages are disposed on the substrate such that a first area and a second area, each determined by vertices corresponding to LED packages, are defined on the substrate. The thermistor is disposed in the first area, and the FET is disposed in the second area, which is outside of the first area. The thermistor detects a temperature in the first area. Such a configuration allows the thermistor to detect, in accordance with the temperature in the area, the temperature of heat transferred from the LED packages, without being affected by heat generated by the FET. This makes it possible to efficiently make temperature corrections to stabilize color temperature and luminance.

摘要： The present invention relates to a display that uses a polysilicon liquid crystal panel.An object of the present invention is to sufficiently secure a hold period and a setup period upon a rise of a source start pulse signal (SSP) without increasing power consumption or increasing circuit scale.A display control circuit (200) includes a source start pulse signal generating circuit (2311) that generates a source start pulse signal (SSP); and a source shift clock signal generating circuit (2313) that generates a source shift clock signal (SCK). The source shift clock signal generating circuit (2313) shortens a period during which the source shift clock signal (SCK) is maintained at a high level, only during a period of time which is immediately before the source start pulse signal (SSP) rises in each horizontal scanning period, based on a source shift clock modification command signal (K) to be outputted from the source start pulse signal generating circuit (2311).
