Abstract: Disclosed includes an apparatus, a drive method, a display panel, and a display device. The apparatus may comprise a drive transistor, a light emitting device driven by the drive transistor and a comparator. The comparator may have a first input coupled to a pixel voltage, a second input coupled to a reference voltage, a first control terminal coupled to a first control voltage, a second control terminal coupled to a second control voltage, and an output coupled to a gate of the drive transistor. The comparator may be configured to output the first control voltage to the output during a first time period in which the pixel voltage is not smaller than the reference voltage and output the second control voltage to the output during a second time period in which the pixel voltage is smaller than the reference voltage.
