The invention discloses a display device structure and a preparation method thereof. The display device structure comprises a substrate, a TFT driving circuit is arranged on the substrate, and an OLED light-emitting device is arranged on the TFT driving circuit through OLED light-emitting device evaporation; a front camera device reserved module is formed at the upper end of the substrate through a TFT and OLED evaporation process; a first inorganic sealing layer, an organic buffer layer and a second inorganic sealing layer are sequentially arranged on the substrate; a camera opening is etched in the middle of the reserved module of the front-facing camera device, the rest part is a reserved part of the reserved module of the front-facing camera device, and the area of the reserved part accounts for one eighth of the whole reserved module of the front-facing camera device. According to the invention, a camera mounting channel does not need to be formed through a physical hole digging mode, and damage to a pac
