Method for manufacturing a display device with low temperature diamond coatings

A method for fabricating an OLED device with multiple low temperature diamond coatings, comprising the steps of:

• a) preparing a backplane for subsequent build up of the OLED device;
• b) depositing a diamond substrate as a base upon the backplane;
• c) depositing an anode layer on the diamond substrate for emitting holes;
• d) depositing a hole transport layer that includes a doped diamond coating residing on the anode layer;
• e) depositing an emissive layer residing on the hole transport layer;
• f) depositing an electron transport layer upon the emissive layer;
• g) depositing a cathode layer upon the electron transport layer for emitting electrons that will drift towards the light-emitting layer;
• h) depositing a diamond coated encapsulation layer for sealing the OLED device from atmospheric moisture;
• wherein the multiple low temperature diamond coatings are all formed on the OLED device, below 750° C., during a single continuous process.
