Abstract
A backlight module of a display panel includes a first light source, a second light source, a first inverter, and a second inverter. The first light source is disposed on a first side of the display panel and includes a first light-emitting device and a second light-emitting device. The second light source is disposed on a second side of the display panel and includes a third light-emitting device and a fourth light-emitting device. The first inverter is coupled to the first and third light-emitting devices, and the second inverter is coupled to the second and fourth light-emitting devices.
Claims16
A backlight module used for display panels comprising:
- a first light source disposed on a first side of a display panel, the first light source comprising a first light-generating device and a second light-generating device;
- a second light source disposed on a second side of the display panel, the second light source comprising a third light-generating device and a fourth light-generating device;
- a first inverter coupled to the first and second light-generating devices;
- and
- a second inverter coupled to the third and fourth light-generating devices.
A backlight module used for display panels comprising:
- a first light source disposed on a first side of a display panel, the first light source comprising a plurality of first light-generating devices and a plurality of second light-generating devices, wherein the first and second light-generating devices are disposed in parallel with each other in an alternating manner;
- a second light source disposed on a second side of the display panel, the second light source comprising a plurality of third light-generating devices and a plurality of fourth light-generating devices, wherein the third and fourth light-generating devices are disposed in parallel with each other in an alternating manner;
- a first inverter coupled to the first light-generating devices of the first light source and the third light-generating devices of the second light source;
- and
- a second inverter coupled to the second light-generating devices of the first light source and the fourth light-generating devices of the second light source.
A method for driving a backlight module of a display panel comprising:
- detecting the brightness of images to be displayed by a display panel;
- and
- when the brightness of images to be displayed by the display panel is smaller than a predetermined value, turning on light-generating devices of a first light source disposed at a first side of the display panel and turning off light-generating devices of a first light source disposed at a second side of the display panel using a first control unit.
