  • Patent number: 8702262
    Abstract: The light sourcing module of a backlit LCD display apparatus includes a light sources and power sources supporting substrate. The supporting substrate supports plural light sources on a top major surface thereof and at least one heat generating and power supplying circuit element that protrudes from a bottom major surface of the supporting substrate. The supporting substrate integrally includes wiring that couples driving power output by power supplying circuit element to the plural light sources. A rear receiving frame includes an integral heat-sinking and dissipating recess or groove that is positioned and dimensioned to receive the power supplying circuit element when the supporting substrate is received by the rear receiving frame. The integral heat-sinking and dissipating recess or groove removes heat from the heat generating and power supplying circuit element so that such heat does not adversely affect performance of the light sources.
