Abstract

The embodiment of the present invention discloses an OLED display panel, which includes a plurality of pixel structures arranged in an array, each pixel structure includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, wherein the blue sub-pixel is A laminated device structure, which sequentially includes 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 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 a driving device. Implementing the embodiments of the present invention can reduce the content of short-wave blue light wavelengths in the display device, realize low blue light display of the OLED display device, and ensure that the display device has a higher color gamut.

Description

technical field [0001] The present 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 ...
