摘要： The invention provides a driving method and a driving system for a display panel. The driving method comprises: partitioning the display panel into N display sub-areas, each of which is used for displaying the 1/N sub-picture of the whole frame of picture to be displayed and correspondingly controlled by one timing controller, wherein N≧2 and N is an integer, and the data signal of the whole frame of picture to be displayed is allocated to each of the timing controllers. According to the driving method and the driving system, by allocating the data signal of the whole frame of picture to be displayed to each of timing controllers, the backlight brightness provided by the different backlight sub-areas is the same, and then a joint or boundary phenomenon occurring among the different backlight sub-areas is avoided.

摘要： A double-sided display device includes: a first display layer, configured to implement output of a display signal of a first side; and a second display layer, configured to implement output of a display signal of a second side; a conversion layer positioned between the first display layer and the second display layer, which switches between a light-transmitting state and an opaque light-shielding state. The conversion layer is in the light-shielding state during a display phase, and in the light-transmitting state during an interfering phase which follows the display phase. During the interfering phase, the first display layer is further configured to output a first interfering signal to interfere with the image displayed by the second side, and the second display layer is further configured to output a second interfering signal to interfere with the image displayed by the first side.
