BACKLIGHT MODULE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/126737
Kind Code:
A1
Abstract:
A backlight module and a display apparatus. The backlight module comprises a first data line (130), a second data line (140) and a light-emitting diode set (120), wherein the light-emitting diode set (120) comprises two or more light-emitting diode units (121) which are connected in parallel, and two ends of each light-emitting diode unit (121) are respectively connected to the first data line (130) and the second data line (140). The voltage at the connection point of the nth light-emitting diode unit (121) and the first data line (130) is defined as Vn, and the voltage at the connection point of the nth light-emitting diode unit (121) and the second data line (140) is defined as Un; and when Vi is larger than Vj, Ui is larger than Uj, so that current flow directions of the first data line (130) and the second data line (140) are the same, and the current flowing into each light-emitting diode unit (121) tends to be consistent.
