| description | Aspects of the subject technology relate to an electronic device with a display. The display includes a plurality of light-emitting diodes and first and second driver circuits coupled to the plurality of light-emitting diodes. The first driver circuit is configured to receive a first pulse-width modulated (PWM) signal to control a first current mirror branch and the second driver circuit to receive a second PWM signal to control a second current mirror branch to provide an extra N bits of resolution for controlling the plurality of the light-emitting diodes. |
