Abstract

The invention provides an OLED display screen and a preparation method thereof and a display device. The OLED display screen comprises a first back plate, a fixing piece, a second back plate, a display panel and a flexible polaroid. The flexible polaroid and the display panel extend from the face, away from the fixing piece, of the first back plate and are bent to the face, away from the fixing piece, of the second back plate, and a gap without filler exists between the display panel and the fixing piece. According to the invention, the existing MLC dispensing process is removed; the flexibility and the ductility of the flexible polaroid are utilized; the length of the flexible polaroid is increased, so that the flexible polaroid is bent from the upper surface of the first back plate and extends to the lower surface of the second back plate, the problems that colloid interferes with other parts in the bending area and wave warping occurs in the bending area can be effectively avoided,and the quality of the OLED display screen is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display screen, a manufacturing method thereof, and a display device. Background technique [0002] With the wide application of OLED technology in the display panel industry, the biggest advantage of OLED products lies in their flexible and foldable characteristics. [0003] At present, the pad bending (panel bending) technology of the display is made into a large R arc, and the bending radius R is between 3mm and 5mm, which cannot increase the screen-to-body ratio of the display. [0004] After the display panel undergoes LLO (Laser Lift Off, laser lift off), the pad bending area relies on MLC dispensing to protect itself. Generally, the dispensing thickness of the pad bending area is generally 50-80 μm, but there will be uneven thickness after the liquid glue is cured, resulting in a gap (Gap) between the glue and the film (Film) layer, so that it is bent ...
