The mirror surface OLED display screen 2 can be used as a cosmetic mirror in a screen-off state; under the power-on state, the high-definition display screen is used, and because the placed position is just a bit above the sight line of the user, the user can lie on the seat comfortably without lowering the head to watch the screen, and the sight line is just raised to the position of the display screen, so that the user experience is greatly optimized.
Furthermore, the invention designs the OLED display screen into a structure which can be folded left and right or can be folded up and down by utilizing the characteristic that the OLED display screen is flexible and foldable; accordingly, the position of the display drive IC 3 changes with the position of the fixed end. The mirror surface OLED display screen 2 is installed on the sun shield body 1, and under the folding state, movable one end is folded to fixed one end, and display drive IC 3 and display switch 4 are located fixed one end for provide stable electrical signal and control signal.
Referring to fig. 1 (a), 2 (a), the mirror OLED display 2 may be used together with a sun visor body (back panel) to block sunlight when in a folded state. Referring to fig. 1 (b) and fig. 2 (b), when the mirror surface OLED display screen 2 is in an unfolded state, the screen can be used as a mirror; when the power-on signal is on, the display can be used as a display.
In the invention, the mirror OLED film structure is an improvement on the basis of a common OLED structure.
See fig. 3 (a) and 3 (b), wherein the TFT backplane 6, i.e. the driving circuit part of the OLED, is the "switch" that controls the light emission of the OLED; the anode 7 provides positive charge to the light emitting device; the pixel definition layer PDL (8) is an organic matter and defines a luminous pixel area, so that the anode of the area is exposed and is respectively connected with the R luminous layer 9,G luminous layer 10 and the B luminous layer 11; a cathode film layer 12 is arranged on the light-emitting layer to provide negative charge for the light-emitting device; the first encapsulation layer 13 is composed of a three-layer structure of CVD1 (typically SiOx) +IJP (leveling layer) +CVD2 (typically SiNx), and plays a role in preventing invasion of water and oxygen and protecting the light-emitting device; POL (polarizer) 14 is used to prevent the reflective layer. The reflected light A0 cannot be emitted due to the mismatch of the polarization directions.
As shown in fig. 4 (a), in the present invention, on the basis of the above prior art, POL (polarizer) 14 is first removed from the mirror OLED film; secondly, a mirror metal layer 15 is added, so that the OLED has a mirror effect when the OLED is in a screen-off state. As shown in fig. 4 (b), both the anode reflected light A1 and the mirror metal layer reflected light A2 can be reflected, so that the face can be cleared. Thirdly, the mirror metal layer 15 is designed to be opened at the position of the RGB sub-pixel, so that the RGB luminescence emission is not affected, and the mirror metal layer 15 is positioned on the first packaging layer 13 and separated from the cathode through the first packaging layer made of non-metal materials, so that the normal conduction of the cathode is not affected, the cathode is not etched by an etching process, the integrity of the cathode film layer can be ensured, and the lighting effect of the OLED is not affected. Finally, a second encapsulation layer 16 is added, and the second encapsulation layer is also formed by a three-layer structure of CVD1, IJP and CVD2, so that the mirror metal layer 15 is protected, and meanwhile, the reliability of the whole OLED device is improved.
As shown in fig. 4 (b), compared with fig. 3 (b), the mirror metal layer 15 is designed more, and compared with the common OLED structure, the light emitting angle of the mirror OLED is smaller than that of the common OLED, so that the mirror OLED has the peep-proof effect, and the secondary driving screen does not influence the primary driving when the mirror OLED is used for entertainment operation.
As shown in fig. 5 (a), in order to avoid diffraction of light from the opening of the mirror metal layer, the opening of the mirror metal layer of the present invention needs to be not less than 100 times of the wavelength of RGB, and since the wavelength of R > the wavelength of G > the wavelength of B, the metal opening corresponding to R > the metal opening corresponding to G > the metal opening corresponding to B. The wavelength of R light is 600-630 nm, the wavelength of G light is 520-550 nm, and the wavelength of B light is 430-460 nm, so that the metal opening corresponding to R is 60-63, the metal opening corresponding to G is 52-55, and the metal opening corresponding to B is 43-46. Since the limiting resolution of human eyes is 100 and the RGB metal openings are smaller than 100, when the user uses the mirror surface OLED mirror, the user cannot see the metal openings, that is, the user can obtain a good mirror effect experience by using the mirror surface OLED planar structure. The minimum line width of the mirror metal layer can reach 5, and the requirement that the pixel spacing is smaller than 20 can be met, so that the PPI of the mirror OLED display can be larger than 400, and the display of high-definition pictures and videos is supported.
As shown in fig. 5 (b), the metal opening according to the present invention is not limited to a rectangular opening, and may be changed according to the shape of the pixel, or may be designed as an arc-shaped or circular opening, which is less likely to diffract due to the absence of straight lines or right angles.
