Embodiment 1
[0018] A method for preparing an organic electroluminescence display device includes the following steps:
[0019] 1) Print the indium tin oxide ITO anode 2 pattern of the organic electroluminescence display device OLED on the cleaned conductive substrate 1, and the substrate with the printed indium tin oxide ITO anode 2 pattern is ultrasonically cleaned with toluene, ethanol and acetone respectively. Dip and rinse with deionized water. Finally, an ozone ion bombardment treatment was performed in a vacuum chamber, the pressure was controlled at 50 Pa, and the substrate was bombarded for 20 minutes.
[0020] 2) Use vacuum evaporation method to evaporate hole transport layer material N,N'-bis(1-naphthyl)-N,N'-diphenyl- on the substrate with printed indium tin oxide ITO anode 2 pattern. 1,1'-Diphenyl-4,4'-diamine, referred to as NPB, prepares the first hole transport layer 3 of NPB, and the system vacuum is 5×10 -5 Pa, NPB deposition rate is 0.1nm / s, thickness is 80nm.
[0021] 3) On ...
Embodiment 2
[0030] A method for preparing an organic electroluminescence display device includes the following steps:
[0031] 1) Print the indium tin oxide ITO anode 2 pattern of the organic electroluminescence display device OLED on the cleaned conductive substrate 1, and the substrate with the printed indium tin oxide ITO anode 2 pattern is ultrasonically cleaned with toluene, ethanol and acetone respectively. Then immerse and rinse with deionized water, and then rinse with deionized water, then rinse with deionized water, then use toluene, ethanol and acetone for ultrasonic cleaning, and then rinse with deionized water, and finally in the vacuum chamber Carry out ozone ion bombardment treatment, control the pressure between 5 Pa, and bombard the substrate for 5 minutes.
[0032] 2) Use vacuum evaporation method to evaporate hole transport layer material N,N'-bis(1-naphthyl)-N,N'-diphenyl- on the substrate with printed indium tin oxide ITO anode 2 pattern. 1,1'-Diphenyl-4,4'-diamine, refer...
