Title:
DISPLAY APPARATUS HAVING A SELF-LUMINOUS PIXEL MODULE AND A FIRST NON-SELF-LUMINOUS PIXEL MODULE DRIVEN BY A PULSE WIDTH MODULATION DRIVING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/227592
Kind Code:
A1
Abstract:
A display apparatus (10A,10B) has a self-luminous pixel module (20), a first non-self-luminous pixel module (30), and a pulse width modulation (PWM) driving circuit (70). The self-luminous pixel module (20) has a plurality of self-luminous pixels (200). The first non-self-luminous pixel module (30) is disposed on the self-luminous pixel module (20) and has a plurality of first non-self-luminous pixels (300). The self-luminous pixel module (20) of the display apparatus (10A,10B) is used as a backlight for the non-self-luminous pixel module (30). The PWM driving circuit (70) provides first PWM signals (C1) to the self-luminous pixel module (20) to control values of brightness of the self-luminous pixels (200) and provides second PWM signals (C2) to the first non-self-luminous pixel module (30) to control values of transmittance of the first non-self-luminous pixels(300).
