Application Case

"Preparation of flexible display by evaporating polymer"

Evaporating polymers to prepare flexible displays is a complex and precise process that requires special techniques and materials to ensure the quality and performance of the final product. Here is an overview of the process for preparing a flexible display in a glove box using evaporation technology:

Materials and equipment preparation

Polymer materials:

1. Choose polymers with good optical, electrical, and mechanical properties, such as polyimide (PI), polyester (PET), or organic semiconductor polymers.

Glove box and evaporation coater:

1. The glove box must be kept in an oxygen-free and water-free environment.

2. Evaporation coating instrument should be equipped with high-precision temperature control system and thickness monitoring system.

Substrate material:

1. Flexible transparent substrates are usually used, such as polyimide film or mylar film.

2. Clean and dry the substrate in advance.

Preparation procedure

Substrate treatment:

1. Clean the substrate, remove surface impurities, and plasma treatment if necessary to improve adhesion.

2. Deposit a conductive layer on the substrate, such as indium tin oxide (ITO) or other transparent conductive film.

Evaporation process:

1. Place the polymer material in the evaporation source.

2. Use a high vacuum pump to vacuum to 10^-6 Torr or lower to ensure a good coating environment.

3. Slowly heat the polymer and control the evaporation rate to obtain a uniform film.

4. Control patterned deposition by rotating substrate or using mask.

Multi-layer structure:

1. If a multi-layer structure is required, such as an organic light-emitting diode (OLED) or organic photovoltaic (OPV), repeat the evaporation process to deposit multiple functional layers.

2. After each layer is deposited, annealing or other heat treatment may be required to improve interlayer adhesion and performance.

Package:

1. After the deposition of all layers, the packaging process is carried out to protect the active layer of the flexible display, usually using flexible transparent packaging materials.

Post-processing and testing

Performance test:

1. Test the optical, electrical and mechanical properties of flexible displays, including transparency, electrical conductivity, bending durability, etc.

2. Perform reliability tests, such as temperature, humidity, bending cycle, etc.

Defect detection and repair:

3. Use microscopy or other detection methods to find defects in the membrane layer.

4. If necessary, local repair by laser repair or other processes.

Matters needing attention

Uniformity and repeatability: strictly control the process parameters to ensure the uniformity of the film and the consistency of production.

Material selection: Select the right polymer and conductive material for the application to achieve the desired properties.

Environmental control: Keep the glove box clean and oxygen-free to avoid contamination and oxidation.
