Abstract
The present application provides an organic light-emitting diode (OLED) display panel and a laser repair method. The OLED display panel includes color filters with the light transmission rates of greater than 90% for laser light with a wavelength range of 900 nm to 1200 nm, and includes at least one light-emitting pattern containing carbon black. The laser repair method increases the light transmission rates of the filter patterns for the laser light with the wavelength range of 900 nm to 1200 nm, so a laser repair yield is increased.
