<p>A method for driving an edge-lit uneven mark-to-space ratio backlight, comprising: step 1. before actually driving the backlight, simulating a process of driving an edge-lit backlight module according to an even mark-to-space ratio scheme on the basis of a predetermined liquid crystal panel signal and of a backlight scan timing; step 2. analyzing the number of interference signal regions and the interference signal distance that occur when backlight partitions are lit during the simulated process of driving the edge-lit backlight module, sorting the backlight partitions according to the degree of crosstalk caused by the interference signal when the backlight partitions are lit, where the backlight partitions having reduced degree of crosstalk are sorted in the front; step 3. when actually driving the edge-lit backlight module, driving on the basis of the predetermined liquid crystal panel signal and of the backlight scan timing, and allocating increased backlight driving mark-to-space ratio when the backlight partitions sorted at the front are lit. The method for driving the edge-lit uneven mark-to-space ratio backlight, in the backlight module having a scanning feature, utilizes a backlight driving scheme of uneven mark-to-space ratio to improve on crosstalk and to enhance display quality.</p> |
