摘要： A method for managing an image memory in an embedded device is provided. A node is obtained from a linked list of the image memory. It is judged whether valid data is present in a memory block corresponding to the node. When no valid data is present, it is judged whether valid data is present in a memory block corresponding to a previous node of the node. When valid data is present in the previous node, it is further judged whether the valid data is movable. When the valid data is movable, memory block information described in the two nodes is exchanged, and the valid data previously stored in the memory block corresponding to the previous node is moved to the memory block corresponding to the node.

摘要： The present invention relates to an LED backlight module, which includes an LGP, an LED light bar, a backplane, and a heat sink. The LED light bar is mounted on the heat sink at a location close to a light incidence side of the LGP. The heat sink forms upward-extending LGP positioning columns that are fixed with respect thereto. The LGP positioning columns extend upward and through the LGP so as to fix the LGP with respect to the heat sink. The heat sink is arranged on the backplane in a manner of being movable in a light incidence direction. The heat sink is movable with expansion or contraction of the LGP so as to maintain light coupling distance between the LGP and the LED light bar. The LED backlight module prevents the LGP from waving resulting from heat or mechanical interference.

摘要： The present invention provides a light guide plate and a backlight module containing the light guide plate. The light guide plate includes a plate body and a coating layer formed on the plate body. The plate body includes a bottom face, a top face opposite to the bottom face, and a plurality of side faces between the bottom face and the top face. The coating layer is formed on at least one side edge of the top face. The coating layer has a refractive index that is greater than or equal to 1 and less than refractive index of the plate body. The light guide plate uses the coating layer formed on the top face to reflect light back into the light guide plate to confine the light within the light guide plate so as to prevent light leakage and ensure light intensity and homogeneity of the light guide plate.
