A displayed light-adjustment device includes two light-transmitting layers which are arranged oppositely, a display module, and an adjustable light-shading layer. The display module is stacked between the light-transmitting layers. The adjustable light-shading layer is interposed between the first light-transmitting layer and the display module, and the light transmittance of the adjustable light-shading layer is adjustable. When the adjustable light-shading layer is powered off, the light transmittance of the adjustable light-shading layer is greater than 75%, and when the adjustable light-shading layer is powered on, an ultraviolet resistance value of the adjustable light-shading layer is greater than 99%.

Displayed light-adjustment device

A display device includes a stacked structure and an outer frame fixedly receiving the stacked structure therein. The stacked structure includes an intelligence light adjustment layer, a display module, and a light-transmitting reflective layer interposed between the display module and the intelligence light adjustment layer. The intelligence light adjustment layer is configured to present one of a first state or a second state, which are different from each other, based on whether electrical power is applied to the intelligence light adjustment layer. The display module projects display images through the intelligence light adjustment layer in the first state. When the intelligence light adjustment layer is in the second state, the color of the outer frame is the same as the color of the intelligence light adjustment layer.

Display device

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.

System and method for compensating uniformity of brightness

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.
