[0037] The preparation method of the OLED device with the optical resonance layer of the present invention comprises:
[0038] Clean the substrate and prepare a TFT array on the substrate;
[0039] Preparation of color filter film;
[0040] Prepare a flat layer on the color filter film;
[0041] preparing an optical resonant layer on the flat layer in the region corresponding to the G sub-pixel;
[0042] preparing a transparent electrode on the optical resonant layer;
[0043] Preparation of white light OLED devices;
[0044] Encapsulating and completing the preparation of the display device.
[0045] Wherein, the step of preparing the optical resonance layer in the region corresponding to the G sub-pixel includes:
[0046] preparing a first dielectric layer with a thickness of 10-150 nm;
[0047] A second dielectric layer is prepared on the first dielectric layer with a thickness of 0-300nm.
no. 1 approach
[0050] like figure 1 As shown, the OLED device with an optical resonant layer in this embodiment includes a substrate, a TFT array (not shown in the figure) is arranged on the substrate, a color filter film 6 is provided on the TFT array, and the color filter film 6 is divided into R , G, B, and W four colors to filter the white light emitted by the white OLED to form R sub-pixels, G sub-pixels, B sub-pixels and W sub-pixels. According to the needs, the R sub-pixel, G sub-pixel, B sub-pixel and W sub-pixel emit light of different intensities, and the light emitted by the R sub-pixel, G sub-pixel, B sub-pixel and W sub-pixel is mixed to obtain the required color. Display in color. After a plurality of OLED devices are arranged according to a certain rule (such as an array), they cooperate with other components such as a casing to form the display of the present invention.
[0051] figure 1In the illustrated embodiment, a planar layer 5 is provided on the color filter film 6 ...
no. 2 approach
[0061] like figure 2 As shown, the difference between this embodiment and the first embodiment is that the optical resonant layer 4 has a double-layer dielectric structure. That is, the optical resonance layer 4 in the second embodiment includes the first dielectric layer 42 and the second dielectric layer 41 . The preparation method of the OLED device of the second embodiment is as follows:
[0062] 1. Clean the substrate and prepare a TFT array on the substrate;
[0063] 2. Prepare color filter film 6;
[0064] 3. Prepare a flat layer 5 on the color filter film 6;
[0065] 4. Prepare the first dielectric layer 42 in the area corresponding to the G sub-pixel on the flat layer 5, and prepare the second dielectric layer 41 on the first dielectric layer 42 to complete the preparation of the optical resonant layer 4 of the double dielectric layer structure; Area preparation filling layer 4';
[0066] 5. Prepare a transparent electrode 3 on the optical resonant layer 4 and t...
