Abstract
A brightness compensation circuitry includes a data-setting switch unit receiving a data-setting signal, a pixel unit including a pixel driving circuit that receives the data-setting signal during a data-input period to generate a driving current, and a compensation circuit receiving the driving current generated by the pixel driving circuit. The compensation circuit controls the data-setting switch unit to conduct or not conduct by determining whether or not a magnitude of the driving current conforms with a criterion that is associated with target brightness of the pixel unit.
