Claim 4:
5. The transparent display panel according to claim 4, wherein a difference between the first threshold and the second threshold is equal to a difference between the second threshold and the third threshold, and the area of the orthographic projection of the effective modulation area of the liquid crystal layer in the first pixel unit on the light exit surface of the light guide plate, the area of the orthographic projection of the effective modulation area of the liquid crystal layer in the third pixel unit on the light exit surface of the light guide plate, and the area of the orthographic projection of the effective modulation area of the liquid crystal layer in the fourth pixel unit on the light exit surface of the light guide plate decreases successively 5% to 10% of the area of the orthographic projection of the effective modulation area of the liquid crystal layer in the second pixel unit on the light exit surface of the light guide plate.
