Document Type and Number:
WIPO Patent Application WO/2024/016370
Kind Code:
A1
Abstract:
A backlight module (100) and a display apparatus (1000). The backlight module (100) comprises a plurality of light-emitting units (10), at least one driving chip (20) and an adjustment module (30). In the driving chip (20), a control unit (22) is used for controlling, on the basis of a control signal (EM), a corresponding light-emitting unit (10) to emit light; the control unit (22) is provided with a feedback node (Fb); and a signal collection unit (21) is connected to the feedback node (Fb), so as to collect a feedback voltage of the feedback node (Fb). The adjustment module (30) is connected to the driving chip (20) and is used for adjusting the light emission brightness of the plurality of light-emitting units (10) according to the feedback voltage.
