Embodiment Construction

[0013] see figure 2 , is a flowchart of a preferred embodiment of the manufacturing method of the polymer light emitting diode of the present invention. The manufacturing method of polymer light-emitting diodes comprises the following steps: providing a base; forming an anode layer on the base; forming a polymer light-emitting layer on the anode layer; ultrasonically treating the polymer light-emitting layer; baking the polymer light-emitting layer ; Sealing the polymer light-emitting layer. details as follows:

[0014] (1) Provide a base

[0015] The substrate acts as a carrier for other components, and its material is usually glass, organic film or plastic.

[0016] (2) Forming the anode layer

[0017] The anode layer is formed on the substrate. The anode layer may be a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO), or a thin metal conductive film through which light can pass. The anode layer can be formed by sputtering. T...

Abstract

The method for fabricating high molecular light emitting diode (LED) includes steps: providing a base plate; forming an anode layer on the base plate; forming a high molecular luminous layer on the anode layer; using ultrasonic to process the high molecular luminous layer. The method can produce high molecular LED with higher purity of luminescence.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a polymer light-emitting diode. 【Background technique】 [0002] With the rapid development of science and technology, people's requirements for display devices are also increasing day by day, making the display devices develop in a direction of being lighter, thinner, and more power-saving, and thus organic light-emitting diode displays are produced. Compared with liquid crystal displays, organic light-emitting diode displays are self-illuminating displays, and do not require a backlight module with high energy consumption, so they can be lighter, thinner, and more power-saving. [0003] According to the different organic thin film materials used, organic light emitting diodes can be divided into small molecule light emitting diodes and polymer light emitting diodes. [0004] Organic light-emitting diodes usually include a multi-layer film structure such as an electron injection layer, an electron ...
