Abstract: The present disclosure is related to a touch technology field and provides a backlight module and a touch display device using the backlight module. The backlight module includes a substrate, plural driving electrode lines, plural receiving electrode lines, and plural light sources. The driving electrode lines are disposed on the substrate. The receiving electrode lines are disposed on the substrate, in which the receiving electrode lines and the driving electrode lines define plural light source regions on the substrate. The lights sources are disposed in the light source regions, in which each of the light source regions includes at least one of the light sources. The touch display device includes the backlight module and a display panel. The backlight module is configured to provide backlight light. The display panel is disposed on the backlight module to use the backlight light to display images.

Abstract: A system and a method for compensating uniformity of brightness are provided. The system includes an edge-type backlight assembly, a display panel, a brightness sensor, a compensating calculator, and a local dimming controller. The display panel is disposed above the edge-type backlight assembly. The display panel includes plural regions for local dimming. The brightness sensor is configured to measure whether the brightness distribution of the display panel is uniform. When the brightness distribution of the display panel is not uniform, the compensating calculator calculates a brightness compensation value corresponding to each of the regions of the display panel. The local dimming controller is configured to drive the edge-type backlight assembly according to the brightness compensation value corresponding to each of the regions of the display panel.
