A backlight module comprising a light source and a diffusion plate disposed immediately opposite a light exiting surface of the light source.

Backlight module and display device

Disclosed are a backlight module and a display device and method using the same, the backlight module comprises light-guide plate (), an optical film () attaching to a side of a light emitting face of the light-guide plate (), and a strip-like assembly () of point light source disposed at the side of the light incident face of the light-guide plate (), the strip-like assembly () of point light source comprises point light sources toward the light incident face of the light-guide plate () thereon, an edge of one side of the optical film () corresponding to the light incident face of the light-guide plate () is provided with indents ().

Backlight module, display device and method for eliminating hotspot effect

Embodiments of the present invention disclose a backlight and a display device, to reduce the number of LEDs in a backlight, save costs, while avoiding dark areas appearing on the screen, so as to ensure display effect. The backlight comprises a first light guide plate and at least one light-emitting diode assembly, and the light-emitting diode assembly is located on one side of the first light guide plate. The light-emitting diode assembly comprises a second light guide plate, at least one light-emitting diode and a reflective film, wherein the at least one light-emitting diode is located on at least one side of the second light guide plate, and the reflective film is located on at least one side of the second light guide plate.

Backlight and display device

The handling of occlusions in stereo imaging is disclosed. In one implementation, an association between a discontinuity in one stereo image and an occlusion in a second stereo image is utilized. In such an implementation, the first and second stereo images are segmented. A mapping of a discontinuity within the second stereo image is used to form at least part of a boundary of an occlusion in the first stereo image. The mapped discontinuity is found at a boundary between two segments in the second stereo image, and once mapped, divides a segment in the first stereo image into two patches. An energy calculation is made in an iterative manner, alternating with changes to a solution with the disparities and occlusions of the patches. Upon minimization, disparities and occlusions at the patch and pixel level are available.
