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.

A data line driving circuit for a display device having a plurality of data lines is provided to include a plurality of data line drivers respectively coupled to the data lines. Each data line driver includes a register unit to store video data having a pixel value, a pulse width modulation unit generating a PWM signal having a pulse width positively correlated with the pixel value, and a charge-discharge unit performing charge-discharge operation to generate a data voltage on a respective one of the data lines according to the PWM signal. A magnitude of voltage variation on the respective data line is positively correlated with the pulse width of the PWM signal during the charge-discharge operation.
