BACKLIGHT SOURCE, DISPLAY DEVICE, AND PARTITION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/093222
Kind Code:
A1
Abstract:
The present application relates to a backlight source, a display device, and a partition control method. The backlight source (10) comprises multiple light-emitting elements (12), a lamp panel (14), and a transmission member (16). The multiple light-emitting members (12) are arranged on the lamp panel (14) and electrically connected to the lamp panel (14). The transmission member (16) rotates to drive the lamp panel (14) to rotate at a preset rotation rate, and the lamp panel (14) drives the multiple light-emitting elements (12) to rotate at the preset rotation rate, so as to form an area light source comprising multiple partitions, wherein the multiple partitions can emit light simultaneously or individually. According to the backlight source (10), the light-emitting elements (12) are driven to rotate at a high speed, and the on/off or the brightness of the light-emitting elements (12) is adjusted according to different positions of different light-emitting elements (12), so that large-area backlight is achieved using fewer light-emitting elements, and there is no need to use a large number of light-emitting elements, thereby effectively reducing the costs and power consumption of manufacturing a backlight module.
