Abstract
A display and a sub-pixel driving method therein are provided. The display includes a data line and a sub-pixel. The data line is configured to provide a data voltage signal. The sub-pixel includes a driving unit, a first light-emitting unit and a second light-emitting unit. The driving unit is configured to generate a driving current according to the data voltage signal. The first light-emitting unit is configured to emit light by the driving current and generate an operating voltage according to the driving current. The second light-emitting unit is selectively substituted for the first light-emitting unit to emit light according to a variation of the operating voltage.
