A display device includes a circuit substrate, a plurality of first pads, a plurality of light-emitting elements, an encapsulation layer and a conductive layer. The plurality of first pads is disposed on the circuit substrate. The plurality of light-emitting elements is disposed above the circuit substrate, and each light-emitting element includes a first electrode, a second electrode, and a light-emitting stack located between the first electrode and the second electrode, wherein the first electrodes of the plurality of light-emitting elements are disposed respectively between the light-emitting stacks of the plurality of light-emitting elements and the circuit substrate and electrically connected to the plurality of first pads respectively. The encapsulation layer is disposed on the circuit substrate and between the light-emitting elements. The conductive layer is disposed at an upper surface of the encapsulation layer and electrically connected to the second electrode.

A nested chopper circuit includes a first chopper section, which is coupled to input terminals and is controlled by a pair of non-overlapping clocks, and a second chopper section, which is coupled to the first chopper section and is controlled by a pair of chopper clocks. The pair of non-overlapping clocks is a multiple of the pair of chopper clocks, and the non-overlapping clocks are configured to invert on a period continuously. When the pair of chopper clocks (&phgr; and &phgr; ) controls switches S , S , S , and S of the second section, these switches follow the following logic when operated in conjunction with the pair of non-overlapping clocks (&phgr;A and &phgr;B): switches S & S : &phgr;A&middot;&phgr; &plus;&phgr;B&middot;&phgr; ; and switches S & S : &phgr;A&middot;&phgr; &plus;&phgr;B&middot;&phgr; . A method for chopping an analog input signal for sampling also is described.
