Claim Text:
1. A display panel, comprising: a display unit, a plurality of parallax barriers capable of working with natural light, wherein a display surface of the display unit is provided with the parallax barriers, wherein each of the parallax barriers comprising: a transparent barrier provided with at least two sets of patterns which are capable of switching between a light-absorbing state and a light-transmitting state, wherein when one set of the patterns are in the light-absorbing state, a slit grating for 3-dimensional display is formed on the transparent barrier, and the transparent barrier comprises: two transparent substrates that are assembled together to form a cell; liquid medium filled between the two transparent substrates; and transparent electrodes formed on the two transparent substrates respectively, wherein transparent electrodes on at least one of the transparent substrates comprise at least two sets of patterned electrodes which can be energized independently, and each set of patterned electrodes corresponds to one desirable observation point, and the liquid medium in regions corresponding to the patterned electrode can be present in light-absorbing state or the light-transmitting state under different conditions; and a sensor, wherein the sensor is configured to detect a location of a viewer; and according to the location of the viewer the display panel determines which set of patterned electrodes is to be used to provide a parallax barrier so that the desirable observation point of the used patterned electrodes is closest to the location of the viewer.
