Transparent display device and method for enhancing a displaying effect of a real object

A transparent display device, comprising an array substrate, a color substrate disposed opposite to the array substrate, and a scattering liquid crystal cell disposed between the array substrate and the color substrate, wherein a plurality of pixel structures are disposed on the array substrate;

• wherein a photosensitive sensor is disposed in each of the pixel structures, and the photosensitive sensor is configured to control a transmittance of the pixel structure;
• wherein the photosensitive sensor is configured to compare a light intensity of first one of the pixel structures to a light intensity of a second one or more of the pixel structures adjacent to the first one to identify the light intensity through the first one pixel structure, and to increase a voltage applied to the first one of the pixel structures to raise the transmittance of the first one of the pixel structures when the light intensity of the first one of the pixel structures is comparatively low;
• wherein the pixel structure further comprises data lines, scan lines, a thin film transistor, and a pixel electrode disposed in an intersecting region of the data lines and the scan lines, the scan lines are disposed on two opposite ends of the pixel electrode respectively, and the data lines are perpendicular to the scan lines;
• wherein one of two opposite ends of the photosensitive sensor is directly and electrically connected to the scan line, and the other end of the photosensitive sensor is directly and electrically connected to the pixel electrode.
