Abstract

See full text

A display apparatus has a self-luminous pixel module, a first non-self-luminous pixel module, and a pulse width modulation (PWM) driving circuit. The self-luminous pixel module has a plurality of self-luminous pixels. The first non-self-luminous pixel module is disposed on the self-luminous pixel module and has a plurality of first non-self-luminous pixels. The self-luminous pixel module of the display apparatus is used as a backlight for the non-self-luminous pixel module. The PWM driving circuit provides first PWM signals to the self-luminous pixel module to control values of brightness of the self-luminous pixels and provides second PWM signals to the first non-self-luminous pixel module to control values of transmittance of the first non-self-luminous pixels.
