Abstract: The present invention provides a method for modulating backlight sources for flat panel displays (FPD), which comprises: lowing steps: step 31: turning on a display screen; step 32: identifying whether the total number of the BLL groups provided on the backlight module is an odd number or an even number; step 33: turning on the one BLL group located at the center-most region of the backlight module while the total number of the BLL groups is an odd number; step 34: turning on the two BLL groups located at the center-most region of the screen while the total number of the BLL groups is an even number; step 35: turning on the two backlight groups located at the two outer side of the center turned-on backlight groups while turning off the center turned-on backlight groups, and similarly, progressing the turning-on and the turning-off from the center region to the two outer edge of the backlight module and then reverse-progressing respectively from the two edges to the center region, so as to complete a full cycle; step 36: determining whether the display screen is off; if so, the process proceeds to step (37); otherwise, the process goes to step (31); and step 37: ending the process.

Abstract translation: 本发明提供一种用于调制平板显示器（FPD）的背光源的方法，包括：降低步骤：步骤31：打开显示屏幕; 步骤32：识别提供在背光模块上的BLL组的总数是奇数还是偶数; 步骤33：打开位于背光模块的最中心区域的一个BLL组，而BLL组的总数是奇数; 步骤34：打开位于屏幕最中心区域的两个BLL组，而BLL组的总数是偶数; 步骤35：打开位于中心点亮背光组的两个外侧的两个背光组，同时关闭中心开启的背光组，并且类似地，从中心开始打开和关闭 区域到背光模块的两个外边缘，然后分别从两个边缘向中心区域反向进行，以便完成一个完整的周期; 步骤36：确定显示屏是否关闭; 如果是，则处理进行到步骤（37）; 否则，过程进行到步骤（31）; 和步骤37：结束该过程。
