Embodiment Construction

[0042] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0043] see figure 1 and figure 2 , the present invention provides a color OLED device, comprising: an OLED substrate 2, an OLED cover 4 bonded to the OLED substrate 2, and a color conversion layer 6 formed on the OLED cover 4, and an OLED substrate 2 is formed on the OLED substrate 2. Component 22, the color conversion layer 6 includes several quantum dot units, and the light emitted by the OLED component 22 is converted by the quantum dot units of the color conversion layer 6, thereby realizing colorization. High purity, good stability and long life. At least one of the OLED substrate 2 and the OLED cover 4 is made of a transparent material. Preferably, in this embodiment, both the OLED substrate 2 and the OLED cover 4 are glass plates. The...

Abstract

The invention provides a colored OLED device and a manufacturing method thereof. The device comprises an OLED substrate (2), an OLED cover plate (4) attached to the OLED substrate (2), and a color conversion layer (6) formed on the OLED cover plate (4), wherein an OLED element (22) is formed on the OLED substrate (2), the OLED element (22) comprises a light-emitting layer (222), the color conversion layer (6) comprises a plurality of quantum dot units, and light emitted by the light-emitting layer (222) is converted through the quantum dot units of the color conversion layer (6) to achieve colorization. According to the colored OLED device and the manufacturing method, colorization display is achieved through the light-emitting layer and the quantum dot units, the thickness of the light-emitting layer is reduced, and then the thickness of the whole colored OLED device is reduced; besides, quantum dots further have the advantages of being good in stability, long in service life, good in color purity and the like, so the service life of the colored OLED device is prolonged, and color purity is improved; meanwhile, the colored OLED device is simple in manufacturing process and low in cost.

Description

technical field [0001] The invention relates to an OLED device and a manufacturing method thereof, in particular to a color OLED device and a manufacturing method thereof. Background technique [0002] There are several technical routes for the colorization of OLEDs, one is RGB three-color light emission, represented by Samsung. This technology is only suitable for organic small molecule materials that are easy to sublimate. Its advantages are simple and mature process and easy operation. However, due to the need for high-precision masks and precise alignment when preparing high-resolution displays, it leads to low production capacity and high cost. Moreover, due to the large differences in the lifetime, excitation rate, and attenuation of the three primary colors, color casts in color displays are caused. The other is white light + RGB filter technology, represented by LG. Since the mature CF technology of LCD can be used, there is no need for mask alignment, which greatl...
