Embodiment 1
[0060] Such as figure 1 As shown, this embodiment relates to an OLED display device, which comprises: a substrate 1 and a first display device that emits red light, a second display device that emits green light, and a third display device that emits blue light located on the substrate 1 display device. Wherein, the first display device includes a first anode 21, a red light-emitting layer 31, a first cathode 41, and a first light extraction layer 51 arranged sequentially from bottom to top; the second display device includes a bottom-to-top The second anode 22, the green light emitting layer 32, the second cathode 42, and the second light extraction layer 52 are arranged in sequence; the third display device includes the third anode 23, the blue light emitting layer and the blue light emitting layer arranged in sequence from bottom to top layer 33 , third cathode 43 and third light extraction layer 53 . In a preferred embodiment of the present invention, the first anode 21,...
Embodiment 2
[0066] Such as figure 2 As shown, this embodiment is roughly the same as Embodiment 1, and the only difference is that this embodiment reduces the influence layer of the third resonant cavity by arranging the thickness of the third cathode 43 to be smaller than the thickness of the first cathode 41 and the second cathode 42 thickness, and then independently reduce the strength of the resonant cavity of the third display device emitting blue light, so as to achieve the effect of reducing the viewing angle deviation. The advantage of this embodiment is that the achieved control precision is the most accurate.
[0067] In a preferred embodiment of the present invention, the thickness difference between the third cathode 43 and the first cathode 41 and the second cathode 42 is 3-10 nm (for example, 3 nm, 5 nm, 7 nm or 10 nm, etc.).
[0068] The effect of embodiment is further described with concrete experiment below:
[0069] Experiment 1: Fix the color scale CIEY of the blue l...
Embodiment 3
[0076] Such as Figure 5 As shown, this embodiment is substantially the same as Embodiment 1, and the only difference is that this embodiment reduces the thickness of the third light extraction layer 53 by setting the thickness of the first light extraction layer 51 and the second light extraction layer 52. The third resonant cavity affects the thickness of the layer, and then independently reduces the intensity of the resonant cavity of the third display device emitting blue light, so as to achieve the effect of reducing the viewing angle deviation.
[0077] In a preferred embodiment of the present invention, the thickness difference between the third light extraction layer 53 and the first light extraction layer 51 and the second light extraction layer 52 is 40-60nm (such as 40nm, 50nm, 55nm or 60nm, etc.) .
