Abstract

The invention provides an organic light emitting diode device and a manufacturing method thereof. The organic light emitting diode device includes a glass substrate, a glass cover plate and a sealant layer, and the upper surface of the glass substrate includes an array substrate layer, an electroluminescence layer and a first thin film encapsulation layer in turn; the lower surface of the glass cover plate It includes a color filter, a quantum luminescent layer, an optical modulation layer, and an optical isolation layer in sequence; the optical isolation layer is set opposite to the black photoresist layer of the color filter, and is used to block the light emitted by the electroluminescent layer Prevent light leakage. The manufacturing method of the organic light emitting diode device of the present invention comprises the steps of: manufacturing a glass substrate, manufacturing a glass cover plate and packaging into a box. The invention solves the problems of device light leakage caused by the thickness of the box by reducing the box distance between the glass substrate and the glass cover plate and setting an optical isolation layer to block light.

Description

technical field

[0001] The invention relates to the display field, in particular to an organic light emitting diode device and a manufacturing method thereof. Background technique

[0002] An organic light emitting diode device (Organic Light Emitting Diode, OLED) is also called an organic electroluminescent display or an organic light emitting semiconductor. Because of its characteristics such as self-illumination, infinitely high contrast, wide viewing angle, low power consumption, extremely fast response speed, and flexible display, it has been regarded as a new generation of display technology since its discovery.

[0003] QD-OLED takes into account the brightness of quantum dots, OLED's independent light emission and ultra-thin design. The industry is currently in the research and development stage, and its application in the display terminal market in the future may have a chance to emerge. QD-OLED is more like a combination of quantum dots and OLED. Using blue OLED a...

Embodiment Construction

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

[0041] In the present invention, the same or corresponding components are represented by the same reference numerals regardless of the figure number, and throug...
