Array substrate, manufacturing method thereof, and display device

Abstract

The invention discloses an array substrate, which comprises a plurality of pixel units located on the substrate. The pixel units include: 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 on the pixel unit. In the pixel area, the organic light-emitting diode includes a transparent first electrode, a light-emitting layer, and a second electrode that reflects light in sequence in a direction away from the substrate; a semi-reflective and semi-transparent layer is located between the organic light-emitting diode and the thin film transistor structure; the color filter, It is located between the second electrode of the organic light-emitting diode and the semi-reflective layer; the second electrode of the organic light-emitting diode and the semi-reflective layer form a microcavity structure. Also disclosed are a manufacturing method of the above-mentioned array substrate and a display device comprising the above-mentioned array substrate. The invention realizes the structure on the array substrate, and the microcavity structure with simple manufacturing process.

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 emission color in the visible light region, and easy large-area and flexible bending. 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] Such as 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 betwe...

Problems solved by technology

[0005] Depend on figure 2 and image 3 It can be seen that although the existing microcavity structure increases the light transmittance, the hierarchical structure of the existing microcavity structure is relatively complicated, and the corresponding regions of the filters of each color are made of microcavity structures with different thicknesses. , the production process is more complex
