Abstract

The present application discloses a display panel and a manufacturing method thereof, wherein the thin film encapsulation layer of the display panel is composed of a first structural layer and a second structural layer with a lower refractive index than the first structural layer, the first structural layer and The second structure layer constitutes a plurality of first converging lens structures and first diverging lens structures, and the first converging lens structures are located in the light emitting direction of the third sub-pixel, and the first diverging lens structures are located in the first sub-pixel or the second sub-pixel In the light emitting direction of the pixel; in order to achieve the purpose of converging blue light and diverging red or green light, so as to reduce the amount of blue light emitted by the display panel in the direction of large viewing angle and increase the green light emitted by the display panel in the direction of large viewing angle or the amount of red light, to improve the phenomenon that the display screen appears bluish when the user uses the display panel to browse the screen with a large viewing angle.

Description

technical field [0001] The present application relates to the technical field of display devices, and more specifically, to a display panel and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, the application of display panels is becoming more and more extensive. OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel has become a rising star in the display panel industry due to its advantages of fast response, brilliant color, thinness and convenience. [0003] However, when the user browses the content displayed on the OLED display panel at a large viewing angle (the angle between the line of sight and the vertical line of the light-emitting surface of the display panel), there will be a problem that the display screen is bluish, that is, the brightness of blue light is relatively high, while Display abnormality caused by low brightness of red and green. refer to figure 1 , figu...
