Abstract

The invention discloses an OLED display panel comprising a plurality of pixel structures arranged in an array, and each pixel structure comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel, and is characterized in that the blue sub-pixel is of a laminated device structure and comprises a substrate layer, an anode layer, a first electroluminescent layer, a charge generation 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 peakwavelength, wherein the first blue light peak wavelength is greater than the second blue light peak wavelength. The invention further provides a corresponding driving method and driving device. According to the embodiment of the invention, the content of short wave blue light wavelength in the display device can be reduced, the low-blue light display of the OLED display device is realized, and meanwhile, the high color gamut of the display device can be ensured.

Description

technical field [0001] The invention relates to the display field, in particular to an OLED display panel, a corresponding driving method and a driving device. Background technique [0002] Organic light emitting diodes (Organic Light Emitting Diode, OLED) have the characteristics of self-illumination, using a very thin organic material coating and glass substrate, when the current passes through, the organic material will emit light, and the organic light emitting diode display screen has a large viewing angle , and can significantly save power, so organic light-emitting diodes are now more and more widely used; [0003] With the increasing popularity of portable terminal display devices such as mobile phones and tablets, people spend more and more time in contact with such terminal display products every day, and the blue light radiation received by human eyes is also increasing, causing more and more damage to human eyes. big damage. At present, the development of panel...
