Embodiment 1
[0066] figure 1 An OLED display panel S1 is provided, including the following structure from bottom to top:
[0067] Substrate 1, silver reflective electrode (100nm), ITO electrode 2 (15nm), first hole transport layer 3 (10nm), second hole transport layer 4 (110nm), light emitting layer 6 (30nm), first electron transport layer Layer 7 (30nm), second electron transport layer 8 (5nm), magnesium-silver electrode (magnesium-silver mass ratio 9:1wt) 9 (15nm) and covering layer 10, and described covering layer is passed Obtained by evaporation, the thickness of the covering layer is 70nm, and the refractive index n of the covering layer is 450~650nm >1.76, the refractive index of 450nm, 530nm, 620nm is 1.84, 1.78, 1.76 respectively;
[0068] The first hole transport layer is (P-type dopant material) material and Doping, the mixing ratio is 5:95 (mass ratio); the second hole transport layer is Material; light-emitting layer is BD :BH Materials, 5:95; the first electron t...
Embodiment 2
[0070] The difference from Example 1 is that the material of the covering layer is The thickness of the covering layer is 70nm, and the refractive index n of the covering layer 450~650nm >1.8, the refractive indices of 450nm, 530nm, and 620nm are 1.95, 1.87, and 1.82, respectively.
