In addition, the reflectivity of each of the light reflecting layers 4 is less than 45%. When the liquid crystal display 12 is activated, some light can still enter the second light transmitting plate 3 through the first light transmitting plate 21, and the touch screen mirror structure 10 is allowed. Has the function of displaying the screen.

As shown in FIG. 4, which is another embodiment of the touch screen mirror structure 10 of the present invention, the embodiment of FIG. 4 is substantially the same as the embodiment of FIG. 3. The embodiment of FIG. 4 differs from the embodiment of FIG. 3 in that An optical interference damage layer b is disposed between the two light reflecting layers 4.

Further explanation is as follows. It is known that the phenomenon of Newton's rings often occurs when the two reflective layers are close together, and the Newton's ring is a texture formed by optical interference phenomena. Directly directing the monochromatic light to the two reflective layers. With proper adjustment, one ring of light and dark circles can be observed. If white light is directly directed to the two reflective layers, rainbow-shaped circular colored stripes can be observed, which in turn affects The light perception of the light-transmissive plate.

Therefore, an optical interference damage layer b is added between the two light reflecting layers 4 on the two adjacent faces a of the embodiment to avoid the occurrence of a Newton ring between the two reflective layers 4, thereby improving the touch screen mirror structure 10. Texture. The optical interference damage layer b may be a surface roughened film layer, such as an anti-Newton ring optical film layer or an optical diffusion film layer, or an optical phase film layer, such as a polarizing film layer or a phase difference film layer. The polarizing film layer may be linear, circular or elliptical, and the retardation film layer may be a quarter phase or a multiple of the phase difference film.
