    Abstract: The present disclosure relates to a backlight source, a display device, and a driving method thereof, in the field of field of displays. The backlight source includes a Passive Matrix Organic Light Emitting Diode (PMOLED) display device, wherein the PMOLED display device includes a transparent substrate. A transparent wiring layer, an anode layer, a light emitting layer, a transparent cathode layer, and a transparent pixel definition layer are arranged on the transparent substrate subsequently. The light emitting layer includes a plurality of light emitting units for emitting white light, and the plurality of light emitting units are arranged in an array. The anode layer includes a plurality of anodes, the plurality of anodes are arranged below the corresponding plurality of light emitting units respectively, and can reflect light emitted from the corresponding light emitting units. The backlight source in the present application is implemented with PMOLED display device. The substrate, wiring layer, cathode layer and pixel definition layer of the PMOLED display device can use transparent materials, resulting in high transmittance of the backlight sources in the areas excluding the anodes, such that the transparent display device can have high transmittance.

    Abstract: A 3D display device is provided. The 3D display device includes a display panel and a light source, the display panel including a first substrate and a second substrate, wherein, the light source is disposed on a side surface of the first substrate, and configured to emit light into the first substrate, wherein, light is propagated in the first substrate in a total reflection manner; the 3D display device further includes a light adjustment structure disposed on a surface of the first substrate facing the second substrate; the light adjustment structure is configured to adjust an emergent direction of light incident into the light adjustment structure from the first substrate, such that a first part of light emerging from the light adjustment structure is propagated in a left eye direction through a first display unit of the display panel, and a second part of light emerging from the light adjustment structure is propagated in a right eye direction through a second display unit of the display panel. Thus, a utilization rate and brightness of light can be improved, and a thickness of the display device is reduced.
