Abstract: A display panel and an electronic device are provided. The display panel includes a plurality of pixels, a plurality of pixel driving circuits, a gate on array (GOA) circuit, and an IC chip. A corresponding number of display pulses is provided to the corresponding pixel driving circuit for different refresh frequencies in each display driving cycle so that display durations can be same or similar when displaying at different refresh frequencies. This reduces or eliminates brightness difference or flicker that occurs when refresh frequencies are switched.

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.
