8. A method for manufacturing a display device, comprising:
forming a transparent display panel, wherein the transparent display panel comprises an upper substrate close to a light-emitting side, a lower substrate far away from the light-emitting side and a display unit positioned between the upper substrate and the lower substrate, one side of the lower substrate far away from the display unit comprises a plurality of shading parts, the transparent display panel is a display panel for controlling display pictures in different areas, and the transparent display panel is configured to be transparent or opaque in partial areas;
forming a plurality of juxtaposed particle electrophoresis sections on a converting substrate, each particle electrophoresis section comprising: a plurality of electrodes disposed on a surface of the conversion substrate facing the lower substrate;
the lower substrate and the display conversion substrate are aligned to form a box, and light-tight charged particles are poured into each particle electrophoresis part, the electrodes of the particle electrophoresis parts are configured to enable the light-tight charged particles to block light from passing through or to enable the light-tight charged particles to be arranged in the range of orthographic projection of the light-tight part on the display conversion substrate, and the display conversion unit provides a display background for the transparent display panel;
forming a plurality of juxtaposed lens cells on a collection substrate, the lens cells comprising a focus-adjustable liquid cell comprising a positive electrode and a negative electrode;
aligning the collecting substrate and the display-shooting conversion substrate and filling a first transparent insulating liquid and liquid balls into each focusing liquid box, wherein the liquid balls comprise transparent films, second transparent insulating liquid coated by the transparent films, positive charge particles and negative charge particles, the positive charge particles and the negative charge particles generate movement displacement under the voltage loaded by the positive electrodes and the negative electrodes and form liquid balls with different shapes so as to adjust the focal length of the lens unit, and the refractive index of the first transparent insulating liquid is smaller than that of the second transparent insulating liquid;
the image collector collects images through a particle electrophoresis part configured to be light-transmitting, an area of a transparent display panel configured to be light-transmitting corresponding to the particle electrophoresis part, and a lens unit corresponding to the particle electrophoresis part, and displays the images on the area of the transparent display panel configured to be light-tight.
