Referring to fig. 1, the invention provides a multifunctional sun visor for a vehicle, which comprises a sun visor body 1, wherein a mirror surface OLED display screen 2 is arranged on the sun visor body 1; the mirror surface OLED display screen 2 is electrically connected with a display drive IC 3 through a display switch 4. The mirror surface OLED display screen 2 can be used as a cosmetic mirror in a breath screen state; under the on-state, use as high definition display screen, owing to the position of placing just in time just in a bit above user's sight, so the user need not to lower the head again and see the screen, can comfortably lie in the seat, and the sight just in time raises to the display screen position, has greatly optimized user experience.
Furthermore, the OLED display screen is designed into a structure which can be folded left and right or up and down by utilizing the characteristic of flexible folding of the OLED display screen; accordingly, the position of the display drive IC 3 changes as the position of the fixed end changes. Mirror surface OLED display screen 2 installs on sunshading board body 1, and under fold condition, mobilizable one end is folded to fixed one end, shows that driver IC 3 and display switch 4 are located fixed one end for provide stable signal of telecommunication and control signal.
Referring to fig. 1 (a) and 2 (a), when the mirror OLED display 2 is in a folded state, it can be used together with a sun visor body (back panel) to block sunlight. Referring to fig. 1 (b) and 2 (b), when the mirror OLED display screen 2 is in the unfolded state, the screen can be used as a mirror; when the power is on and the signal is input to lighten the screen, the display can be used.
In the invention, the mirror surface OLED film layer structure is an improvement on the basis of a common OLED structure.
Referring to fig. 3 (a) and 3 (b), the TFT backplane 6, i.e. the driving circuit portion of the OLED, is a "switch" for controlling 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 layer, defines a light-emitting pixel area, exposes the anode of the area and is respectively connected with the R light-emitting layer 9,G light-emitting layer 10 and the B light-emitting layer 11; the cathode film layer 12 is arranged on the luminescent layer and provides negative charges for the luminescent device; the first packaging layer 13 is composed of three layers of structures of CVD1 (generally SiONx) + IJP (leveling layer) + CVD2 (generally SiNx), and plays roles of preventing water and oxygen from invading and protecting a light-emitting device; the POL (polarizer) 14 is used to prevent the reflection layer. The reflected light A0 cannot exit due to the mismatch of polarization directions.
As shown in fig. 4 (a), in the present invention, based on the above prior art, POL (polarizer) 14 is first removed from the mirror OLED film; and secondly, the mirror surface metal layer 15 is added, so that the OLED has the mirror surface effect when the OLED is turned on. As shown in fig. 4 (b), both the anode reflected light A1 and the specular metal layer reflected light A2 can be reflected, so that a human face can be clearly illuminated. Thirdly, the mirror metal layer 15 is provided with an opening at the RGB sub-pixel position, so that the RGB light emission is not affected, and since the mirror metal layer 15 is located on the first packaging layer 13 and is separated from the cathode by the first packaging layer made of non-metallic material, the normal conduction of the cathode is not affected, the cathode is not over etched by the etching process, the integrity of the cathode film layer can be ensured, and thus the lighting effect of the OLED is not affected. Finally, a second packaging layer 16 is added, and is also composed of a CVD1+ IJP + CVD2 three-layer structure, so that the mirror surface metal layer 15 is protected, and meanwhile, the reliability of the whole OLED device is improved.

As shown in fig. 5 (a), in order to avoid the light diffraction caused by the mirror metal layer opening, the mirror metal layer opening of the present invention is not less than 100 times of the RGB wavelength, 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 of an OLED product is 600 to 630nm, the wavelength of G light is 520 to 550nm, the wavelength of B light is 430 to 460nm, so that the metal opening corresponding to R is 60 to 63, the metal opening corresponding to G is 52 to 55, and the metal opening corresponding to B is 43 to 46. Since the limit resolution of human eyes is 100 and the RGB metal openings are all less than 100, when a user looks into a mirror with a mirror OLED, the user cannot see the metal openings, i.e., the mirror OLED planar structure can obtain a good mirror effect experience. The minimum line width of the mirror surface metal layer can reach 5, the requirement that the pixel distance is less than 20 can be met, the PPI of the mirror surface OLED display can be larger than 400, and high-definition picture and video playing 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, and may be designed to be an arc-shaped or circular opening, which is less likely to cause diffraction because there is no straight line or right angle.

(3) A Pixel Definition Layer (PDL) 8, which is an organic compound and may be a transparent or black organic material, is formed by coating, exposure, and development.
(4) Then, by an evaporation process, RGB organic light emitting materials are evaporated by using an FMM Mask (high precision metal Mask), and a cathode layer 12 is evaporated by using an Open Mask, wherein the cathode is generally Mg/Ag or other semitransparent metal film layer.
(5) The first package layer 13 is formed by CVD (Chemical Vapor Deposition) and IJP (Ink Jet Printing) devices, and a CVD1 film (generally, siONx) is deposited by CVD, a leveling layer (generally, a transparent organic material) is printed by IJP, and a CVD2 film (generally, siNx) is deposited by CVD.
(6) The mirror metal layer 15 is formed on the first package layer by processes of sputtering, coating photoresist, exposing, developing, etching, and stripping the photoresist, and the like, and the material is generally a highly reflective metal such as Ag, al, and the like.
(7) Finally, the manufacturing method of the second packaging layer 16 is the same as that in step 5.
