Embodiment 1

[0034] see figure 1 , figure 1 It is a schematic diagram of a first structure of a display panel 100 provided in an embodiment of the present application.

[0035] The embodiment of the present application provides a display panel 100. The display panel 100 includes an array substrate 11, a light-emitting device layer 12, and a color-resist layer 13. The light-emitting device layer 12 is disposed on the array substrate 11. The light-emitting device layer 12 includes a red light-emitting device 1052 , the first blue light emitting device 1051, the second blue light emitting device 1053; the color resistance layer 13 is disposed on the light emitting device layer 12, and the color resistance layer 13 includes a red color resistance 132, a blue color resistance 131, and a green color conversion unit 133; Wherein, the red color resistance 132 is set corresponding to the red light emitting device 1052, the blue color resistance 131 is set corresponding to the first blue light emit...

Embodiment 2

[0056] This embodiment is the same or similar to the above embodiments, except that the structure of the display panel 100 is further described.

[0057] In some embodiments, the color resistance layer 13 further includes a spacer layer 134 , the spacer layer 134 includes a plurality of openings 1341 , and the red color resistance 132 , the blue color resistance 131 and the green color conversion unit 133 are disposed between the spacer layers 134 .

[0058] Specifically, such as figure 1 As shown, the spacer layer 134 includes a plurality of openings 1341 , and the red color resist 132 , the blue color resister 131 and the green color conversion unit 133 are disposed on the openings 1341 of the spacer layer 134 .

[0059] Specifically, the opening of the spacer layer 134 is used to accommodate the red color resistance 132, the blue color resistance 131 and the green color conversion unit 133, and the spacer layer 134 separates the red color resistance 132, the blue color resi...

Embodiment 3

[0065] This embodiment is the same or similar to the above embodiments, except that the structure of the display panel 100 is further described.

[0066] In some embodiments, the display panel 100 further includes a first encapsulation layer 110 , and the first encapsulation layer 110 is disposed on a side of the color resist layer 13 away from the light emitting device layer 12 .

[0067] Specifically, the first encapsulation layer 110 is arranged on the surface of the color-resist layer 13, which can protect the color-resist layer 13, and can also prevent water vapor and oxygen from entering the light-emitting device layer 12 of the display panel 100, so as to avoid the life of the display panel 100. decline.

[0068] Specifically, the first encapsulation layer 110 may include an inorganic material layer, an organic material layer, or a multi-layer laminated structure of an inorganic material layer and an organic material layer.

[0069] In some embodiments, the display pan...

Abstract

The embodiment of the invention provides a display panel, a manufacturing method thereof and a display terminal, a light-emitting device layer comprises a red light-emitting device, a first blue light-emitting device and a second blue light-emitting device, a red color resistor is arranged corresponding to the red light-emitting device, a blue color resistor is arranged corresponding to the first blue light-emitting device, and a second color resistor is arranged corresponding to the second blue light-emitting device. The green color conversion unit is arranged corresponding to the second blue light-emitting device, the green color conversion unit is used for converting light emitted by the second blue light-emitting device into green light, the blue light component in the green light generated by the green color conversion unit is reduced, the half-peak width of the green light is reduced, the color gamut of the organic light-emitting display panel can be improved, and the display effect of the organic light-emitting display panel is improved. Therefore, the organic light-emitting display panel with the ultra-high color gamut is realized.

Description

technical field [0001] The present application relates to the display field, and in particular to a display panel, a manufacturing method thereof, and a display terminal. Background technique [0002] Organic light-emitting display panels (OLEDs) do not require a backlight source. The organic light-emitting display panels include a light-emitting device layer, and light-emitting materials are arranged in the light-emitting device layer. When a current passes through, these light-emitting materials will emit light, thereby achieving a display effect. Compared with liquid crystal display panels (LCDs), organic light-emitting display panels can be made lighter and thinner, have a larger viewing angle, and can significantly save power consumption. In recent years, with the maturity of OLED technology, the penetration rate of OLED on the market has increased year by year. [0003] However, OLEDs are limited by the characteristics of fluorescent and phosphorescent materials thems...
