Claim 12:
13. A method for manufacturing a transparent display panel, comprising:
providing a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate;
providing a light guide plate on a side of the first substrate away from the second substrate, wherein the light guide plate has a light incident surface on an outer peripheral side of the light guide plate;
providing a light source assembly, wherein the light source assembly is configured to emit a light beam toward the light incident surface of the light guide plate; and
providing a plurality of pixel units on the transparent display panel, wherein the plurality of pixel units comprises a first pixel unit and a second pixel unit,
wherein a distance from a center of an orthographic projection of the first pixel unit on a light exit surface of the light guide plate to the light incident surface of the light guide plate is less than a distance from a center of an orthographic projection of the second pixel unit on the light exit surface of the light guide plate to the light incident surface of the light guide plate, and
wherein an area of an orthographic projection of an effective modulation area of the liquid crystal layer in the first pixel unit on the light exit surface of the light guide plate is less than an area of an orthographic projection of an effective modulation area of the liquid crystal layer in the second pixel unit on the light exit surface of the light guide plate;
wherein providing a plurality of pixel units on the transparent display panel comprises:
patterning one or both of a first transparent electrode and a second transparent electrode in the first pixel unit, so that an overlapping area of an orthographic projection of the first transparent electrode in the first pixel unit on the light exit surface of the light guide plate and an orthographic projection of the second transparent electrode in the first pixel unit on the light exit surface of the light guide plate is less than an overlapping area of an orthographic projection of a first transparent electrode in the second pixel unit on the light exit surface of the light guide plate and an orthographic projection of a second transparent electrode in the second pixel unit on the light exit surface of the light guide plate; and
wherein the first pixel unit further comprises a dummy electrode, and the dummy electrode is not electrically connected to the first transparent electrode and the second transparent electrode, and the orthographic projection of the first transparent electrode or the second transparent electrode on the light exit surface of the light guide plate has a hollow area, and an orthographic projection of the dummy electrode on the light exit surface of the light guide plate is located in the hollow area.
