Display and electronic device including the display

Abstract

A novel display is provided. A display having a small change in chromaticity of a micro light-emitting diode in proportion to current density is provided. A display capable of reducing power consumption in the driver circuit when displaying a still image is provided. The display includes a plurality of pixels each including a display element and a microcontroller. The microcontroller includes a first transistor, a triangular wave generator circuit, a comparator, a switch, and a constant current circuit. The first transistor has a function of retaining a potential corresponding to data written to the pixel by being switched off. The triangular wave generator circuit has a function of generating a triangular wave signal. The comparator has a function of generating an output signal corresponding to the potential and the triangular wave signal. The switch has a function of controlling whether or not to make a current flowing in the constant current circuit flow to the display element in accordance with the output signal.
