Abstract: |
The invention discloses a transparent display able to increase contrast, comprising transparent display and at least a transflective film arranged on one side of the transparent display. And it uses the character that the transflective film only reflects half of the light of partial wavelengths to control wavelengths it can reflect by regulating its spiral intervals, so as to match the wavelengths of the reflected light and the device emitted light, obtaining more reflection; in addition, it still has very high transmission with respect to natural light. And the outgoing light intensity on one side is higher than that on the other side so that the contrast is very high and the display effect is good. |
