Abstract

The invention discloses a foldable OLED display panel. The display panel comprises a bending region and a non-bending region, and comprises multiple sub-pixels formed in the bending region and the non-bending region, wherein all or partial sub-pixels have self-luminous characteristics; and a first spacer for providing support and forming gaps, wherein the first spacer is arranged at the bending region and is in a netty distribution to surround multiple sub-pixels. The display panel can enhance the entire capacity of bearing the stress by the sub-pixels in the bending region in the bending process, thereby ensuring the reliability of the display panel.

Description

technical field [0001] The present application relates to a display technology, in particular to a foldable organic light emitting diode (organic light emitting diode, OLED) display panel. Background technique [0002] With the characteristics of being able to bend, fold and stretch at will, and having the advantages of thinness, lightness, small size, low power consumption and high portability, flexible display screens have broad application prospects. For the field of display technology, whether it is foldable, stretchable, or arbitrarily curved, flexible display technology is a technological innovation. [0003] In current dynamic folding display products, the bending axis is fixed. Such as Figure 1A As shown, the bending axis A1 of the half-folded display product is the middle area of ​​the display screen. Such as Figure 1B As shown, the bending axes B1 and B2 of the three-fold display product are respectively 1 / 3 and 2 / 3 of the display screen. The bending radius i...
