Patent ID: 10636343

Abstract:
An embodiment of the present invention discloses an OLED display panel, including a plurality of pixel structures arranged in an array, each pixel structure including a red sub-pixel, a green sub-pixel and blue sub-pixels, wherein the blue sub-pixel is a stacked device structure sequentially including a substrate layer, an anode layer, a first electroluminescent layer, a charge generating layer, a second electroluminescent layer and a cathode layer, wherein the first electroluminescent layer has a first blue light peak wavelength, the second electroluminescent layer has a second blue light peak wavelength, and the first blue light peak wavelength is greater than the second blue light peak wavelength. The invention also provides a corresponding driving method and driving device. By implementing the embodiments of the present invention, it is possible to reduce the content of the blue wavelength of the short wavelength in the display device.
