Backlight assembly, driving method and display device

Abstract

The embodiment of the invention belongs to the technical field of electronics. The invention provides a backlight assembly, a driving method and a display device. The backlight assembly comprises a light source group and a driving module for driving the light source group, wherein the light source group comprises at least one light source pair; the colors of light emitted by two light sources in the light source pair are consistent; a driving module is arranged on a connecting line between two light sources in at least one light source pair, the two light sources are connected with the signaloutput end of the driving module; when the backlight assembly is lightened; the two light sources in at least one light source pair are lightened at the same time, the brightness difference of all areas of the light-emitting surface of the backlight assembly is reduced, and therefore the problem that the brightness difference of the area corresponding to the driving element and the brightness of other areas is large due to the fact that the light sources and the driving element need to be placed in one light-emitting unit at the same time is solved.

Description

technical field [0001] The embodiments of the present invention belong to the field of electronic technology, and in particular relate to a backlight assembly, a driving method and a display device. Background technique [0002] At present, LCD screens usually use a constant-on backlight source, and its black field performance is restricted by the light leakage of the liquid crystal unit, thus limiting the contrast between brightness and darkness. Dynamic backlight technology uses a point light source array as the backlight source of the LCD panel, which can significantly improve the performance of the LCD panel. brightness contrast. Moreover, the scheme of using a TFT (Thin Film Transistor, thin film transistor) backplane to drive the point light source array in an active matrix manner can achieve the advantages of low cost and high reliability. [0003] However, due to the characteristics of the TFT backplane, it is necessary to place circuit components on the front of th...
