Pixel isolation bank and method of manufacturing the same

A pixel isolation bank, comprising:

• a first lyophobic layer located at a predetermined height of the pixel isolation bank;
• a lyophilic layer at a bottom of the pixel isolation bank,
• wherein the pixel isolation bank is an isolation structure,
• the pixel isolation bank is formed by a mixture of different polymers having different properties comprising lyophilic, lyophobic and magnetic properties;
• the polymers are configured to form different layers of the pixel isolation bank due to their different surface energy;
• a second polymer of the polymers having the lyophilic property is configured to gather at the bottom of the pixel isolation bank to form the lyophilic layer, and
• a first polymer of the polymers having the magnetic and lyophobic properties is configured to gather above the lyophilic layer under an action of a magnetic field to form the first lyophobic layer.
