Create an advertising poster for the "OPPO Enco X2" phones, featuring two super tiny argument screens on top of each other in white and silver colors. The background is white with swirling patterns. Include bold text at bottom that reads 'Liken it to liquid crystal sheets' around the screen, and include product details such as model numbers and icons. Emphasize ultra-light theme and a minimalist style. Ensure high resolution and professional photography quality. --ar 9:16 --testp
