Problems solved by technology

[0014] However, currently, in terms of the development level of three-color OLED light-emitting materials, the light quantum efficiency of blue OLED light-emitting materials can only reach the level of 6-8%, and the lifespan is only about 20,000 hours when driven for a long time, which is far behind. The light quantum efficiency of green and red materials is more than 20%, and the service life of hundreds of thousands of hours is the development level
Therefore, in a sense, the relatively backward reality of blue-light OLED materials constitutes a technical bottleneck for the OLED display industry itself, and at the same time, it also hinders the development of large-screen display applications.
It is precisely because of the huge difference in the characteristics of diff...

Embodiment 1

[0105] figure 2 Shown is the first structure of the large-size full-color OLED display of the present invention, which includes a complete color conversion substrate and a display module composed of a plurality of display units. The color conversion substrate includes a transparent substrate 1, and the transparent substrate One surface of 1 is covered with a red filter film layer 5, a green filter film layer 4 and a blue filter film layer 2, and a black matrix net is arranged between the filter film layers of various colors grid film layer 3; its innovative point is: the green filter film layer 4, the red filter film layer 5 and the black matrix grid film layer 3 between them are fully covered with the same green color transformation The green color conversion film layer 6 made of material; the display module is composed of a plurality of display units spliced ​​together, and each display unit includes a light-transmitting substrate 9, a plurality of OLED light-emitting devic...

Embodiment 2

[0160] image 3 Shown is the second structural form of the large-size full-color OLED display of the present invention, which is the same as figure 2 The structural form shown in the difference is that the green color conversion film layer 6 does not continuously cover the red filter film layer 5, the green filter film layer 4 and the black matrix grid film layer 3 between them , but only covers the green filter film layer 4. This composition feature is only a difference in the selectivity of the process of the color change film layer, and does not affect the performance of the large-size full-color OLED display.

[0162] Manufacturing steps process:

[0163] 1. Production of color changing substrate:

[0164] (1) In the form of entrusted processing, the black matrix grid film layer 3, the red filter film layer 5, the green filter film layer 4 and the blue The filter glass of the filter film layer 2 has a specification size of 2.4 inches QVGA, in which the thickness of the red filter film layer 5 is 3 microns, the thickness of the green filter film layer 4 is 3 microns, and the blue film layer 4 has a thickness of 3 microns. The thickness of the filter film layer 2 is 6 microns, and the transmittances of the above-mentioned different color filter film layers are as follows: Figure 6 shown.

[0165] (2) According to figure 2 In the shown structure, the green color conversion film layer 6 is continued to be made on the above-mentioned light filter film glass. In the manufacturing example 1, the green color-changing film layer 6 is in the form of photoresist, specifically, the green c...

Abstract

The invention relates to a large-size full-color OLED (Organic Light-Emitting Diode) display, which comprises a complete color converting base plate and a display module. The large-size full-color OLED display is characterized in that a green color converting film is covered on a green filter plate film; the display module is formed by assembling a plurality of display units; each display unit comprises a transparent base plate, a plurality of OLED luminescent devices and a control loop for driving the OLED luminescent devices to radiate light; the transparent base plates are seamlessly adhered onto a red filter plate film, a green filter plate film, a blue filter plate film, a black matrix grid film and a green color converting film on the color converting base plate through colloidal packing material; and each OLED luminescent device in the display unit has a filter plate film on the color converting base plate corresponding to the OLED luminescent device independently. The large-size full-color OLED display has the advantages of being good in visual effect, high in yield and the like, is capable of being convenient to realize size dimension, and is beneficial for improving the performance price ratio for manufacturing the display.
