摘要： Disclosed are an illuminance sensor which has a spectral-response characteristic approximate to the spectral luminous efficacy and which has a low circuit complexity, and a display device including the illuminance sensor. The illuminance sensor includes (i) a current output circuit which, with use of a bitstream signal of a first analog-digital conversion circuit for carrying out an analog-digital conversion with respect to a first current flowing through a first light receiving element, outputs a current corresponding to the first current and (ii) a second analog-digital conversion circuit which receives a third current obtained by subtracting a current from a second current flowing through a second light receiving element and which thus carries out an analog-digital conversion with respect to the third current.

摘要： A control circuit device 6 is supplied with a buffer circuit 71 that has an input side thereof connected to a PWM input terminal PWN, and the buffer circuit 71 transforms a PWM signal being supplied from the outside to obtain a waveform, whereby an “H” level of a PWM signal that is inputted to an error amplifier 68 by way of an RC filter 8 can be made constant. As a result, it is possible to control an output current to be supplied to the load 7 even when the output current to the load 7 is minimal.
