Abstract
A light source unit in a backlight module able to resist the accumulation of static electricity includes a circuit board, a plurality of lighting elements, a plurality of conductive lines, and at least one connecting line. Each conductive line electrically connects with lighting elements. The conductive line forms a plurality of first sharp portions. A plurality of second sharp portions which are grounded are facing the first sharp portions. The first sharp portions collect static electricity and the second sharp portions cooperate with the first sharp portions to discharge the static electricity.
Claims18
A light source unit in a backlight module, the light source unit comprising:
- a circuit board with a first surface and a second surface facing away from the first surface;
- a plurality of lighting elements located on the first surface and configured to emit light;
- a plurality of conductive lines;
- at least one connecting line parallel with the conductive lines;
- a plurality of first sharp portions located on the conductive lines, and configured to collect static electricity;
- and
- a plurality of second sharp portions located on the at least one connecting line and configured to cooperate with the first sharp portions to discharge the static electricity;
- wherein each of the conductive lines electrically connects with portions of the lighting elements in line;
- the second sharp portions respectively face the first sharp portions.
A backlight module for providing a backlight, the backlight module comprising:
- an optical film layer;
- a light guide plate located on a surface of the optical film layer, and configured to guide light to emit into the optical film layer;
- a reflector layer configured to reflect a leakage light of the light guide plate back into the light guide plate;
- a frame configured to frame the optical film layer, the light guide plate, and the reflector layer;
- and
- a light source unit located on a side of the light guide plate, and configured to generate light, the light source unit comprising:
- a circuit board with a first surface and a second surface parallel with the first surface;
- a plurality of lighting elements located on the first surface, and configured to emit light;
- a plurality of conductive lines parallel with each other;
- at least one connecting line parallel with the conductive lines;
- a plurality of first sharp portions located on the conductive lines, and configured to collect static electricity;
- and
- a plurality of second sharp portions located on the at least one connecting line, and configured to cooperate with the first sharp portions to discharge the static electricity;
- wherein each of the at least one conductive line electrically connects with portions of the lighting elements in line;
- the second sharp portions respectively face the first sharp portions.
