Banner & Witcoff, Ltd.
Light intensity detection circuit, light intensity detector, detection method thereof and display device
A light intensity detection circuit, a light intensity detector, a detection method thereof and a display device are provided. The light intensity detection circuit includes a first reverser, a second reverser, a third reverser, a photosensor and an energy storage element. The first reverser respectively outputs a voltage of the first voltage terminal or the second voltage terminal to the energy storage element under the control of the signal input terminal of the light intensity detection circuit. The second reverser and the third reverser are configured to control transmission of photocurrent generated by the photosensor along a first direction or a second direction. The energy storage element controls a voltage of the signal output terminal of the light intensity detection circuit through voltage storage or voltage release.
