BACK LIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A back light module and a liquid crystal display device are provided. The back light module, which is used in the liquid crystal display device, has a backboard (10) and multiple light emitting diodes; the liquid crystal display device has a display area (12) overlapping with and corresponding to the backboard (10), wherein the display area (12) has a display area center line (14) which has a position center (14-1) relative to the multiple light emitting diodes; the multiple light emitting diodes belong to multiple forward voltage bins (L1-L4), and the light emitting diode belonging to a lower forward voltage bin is set in the position nearer to the position center (14-1), while the light emitting diode belonging to a higher forward voltage bin is set in the position further from the position center (14-1). The back light module can raise the utilization rate of the light emitting diodes, improve the temperature distribution luminance of the light emitting diodes, and further improve the luminance and chrominance uniformity of the light emitting diode back light module.
