Abstract
The present disclosure relates to an organic light-emitting display panel. A dielectric layer having a specific Bragg reflector layer structure is disposed between a polarizer and an organic light-emitting diode device or between a polarizer and a touch control panel. In the first aspect, blue light below 438 nm harmful to human eyes may be greatly reduced. The Bragg reflector layer structure may not only play a role of micro-cavity control, but also form a resonant cavity effect corresponding to organic optical micro-cavities in the device, which achieves effect of controlling spectrum and improving color purity, of the control panel. Different Bragg reflector layer structures may be designed according to different devices and different requirements, to achieve a better effect of protecting human eyes. Besides, the Bragg reflector layer of the dielectric layer may further enhance performance of preventing water and oxygen and improve encapsulation effect.
