Embodiment Construction

[0066] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0067] like Figure 5 As shown, the array substrate of this embodiment includes: a plurality of gate lines and data lines formed on the substrate 1 , and pixel units formed by intersections of the gate lines and the data lines. The pixel unit includes: a thin film transistor structure formed on the substrate and an organic light emitting diode driven by the thin film transistor structure. The organic light emitting diode is located in the pixel area of ​​the pixel unit (usually refers to the display area other than the thin film transistor in the pixel unit), namely Figure 5 Middle A area. The pixel unit also includes a color filter 9 . The organic light emitting diode...

Abstract

Embodiments of the invention disclose an array substrate and a fabrication method thereof, and a display device. The array substrate comprises a plurality of pixel units disposed on a base substrate. Each pixel unit comprises a thin-film transistor region and a display region (A) other than the thin-film transistor region. A thin-film transistor structure is formed in the thin-film transistor region, and an organic light-emitting diode driven by the thin-film transistor structure is disposed in the display region. The organic light-emitting diode comprises a transparent first electrode (11), a light-emitting layer (13), and a second electrode (14) for reflecting light that are sequentially formed in a direction away from the base substrate. A transflective layer (8) is formed in the display region. A color filter film (9) is formed in the display region and is disposed between the second electrode (14) of the organic light-emitting diode and the transflective layer (8). The second electrode of the organic light-emitting diode and the transflective layer form a microcavity structure. The color filter films in the pixel units of different colors have different thicknesses.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diodes, OLED) are considered to be one of the most important display technologies in the future due to their advantages such as simple preparation process, low cost, adjustable luminous color in the visible light region, and easy large-area and flexible bending. one. In particular, the power efficiency of white light OLED (WOLED) has exceeded 60lm / W, and the life span has reached more than 20,000 hours, which has greatly promoted the development of WOLED. [0003] like figure 1 As shown in (a), one of the WOLEDs is doped into an organic light-emitting layer 102 with red, green and blue primary colors, so that the organic light-emitting layer 102 emits white light. The organic light-emitting layer 102 is located be...
