    摘要: The present invention discloses a light emitting diode (LED) lens, a back light module and a liquid crystal display (LCD) device. A LED lens is of a direct type back light module; the dispersion index of said LED lens is less than 0.1; said dispersion index is: k dispersion = ∫ A ⁢ ∑ i ⁢ ⁢ d i d total ⁢ ⁢ ⅆ A ; dA is a microfacet of the main luminous surface of the LED blue chip; di is a solid angle of the incident angle which is just in the critical area when dA light is reflected to the lens; the critical area refers to an area in which light with different wavelengths emitted by the LED is dispersed in the lens; the total solid angle of color separation corresponding to microfacet dA is: ∑ i ⁢ ⁢ d i ; dtotal is the solid angle of the lens light emergent surface corresponding to any microfacet. The present invention can avoid dispersion phenomenon under the condition of guaranteeing wide luminance.

    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.
