BACKLIGHT MODULE AND DISPLAY APPARATUS

摘要

A backlight module including a light guide plate, light source sets, and controlling circuits is provided. The light guide plate has a plurality of regions, and each region of the light guide plate has a light incident surface correspondingly. Each light source set is disposed at the light incident surface of one of the regions of the light guide plate, and each light source set has at least one middle light source and at least one edge light source. The middle light source is disposed in a middle region of the light source set and the edge light source is disposed at an edge of the light source set. Each controlling circuit is electrically connected to the middle light source of one of the light source sets, and the edge light source of each light source set is electrically connected to the controlling circuit of the adjacent light source set.

主权项

1. A backlight module, comprising:
a light guide plate, having a first region and a second region, wherein the first region and the second region of the light guide plate have a light incident surface respectively, and a boundary between the first region and the second region; a first light source set, having a plurality of first middle light sources and at least one first edge light source, wherein the plurality of the first middle light sources are disposed corresponding to the first region of the light guide plate, and the first edge light source is disposed corresponding to the second region of the light guide plate and is disposed adjacent to an edge of the first region of the light guide plate; a second light source set, having a plurality of second middle light sources and at least one second edge light source, wherein the plurality of the second middle light sources are disposed corresponding to the second region of the light guide plate, and the second edge light source is disposed corresponding to the first region of the light guide plate, the second edge light source is disposed adjacent to the plurality of the first middle light sources and is disposed adjacent to an edge of the second region of the light guide plate, the first edge light source is disposed adjacent to the plurality of the second middle light sources, wherein the first region is adjacent to the second region and do not overlap with the second region; a first controlling circuit, electrically connected to the plurality of the first middle light sources of the first light source set, and a second controlling circuit, electrically connected to the plurality of the second middle light sources of the second light source set, wherein the first controlling circuit controls the first middle light source and the first edge light source of the first light source set to light up or not simultaneously, and the second controlling circuit controls the second middle light source and the second edge light source of the second light source set to light up or not simultaneously.
