US Patent 11678514 Organic light-emitting diode (OLED) display panel and display device

The present disclosure provides an organic light emitting diode (OLED) display panel and a display panel which include a display region, a binding region, and a bending region. A metal trace inside the bending regions generates a tensile stress region and a compressive stress region. A plurality of through holes are disposed on the metal trace. A distribution density of the through holes corresponding to the tensile stress region is different from distribution density of the through holes corresponding to the compressive stress region. It may relieve the stress, reduce the problems such as failure and bad products, reduce the bending angle to be smaller, and achieve narrower borders.
