Abstract
The embodiment of the invention discloses an organic light-emitting display device and a manufacturing method thereof and organic light-emitting display equipment. The organic light-emitting display device comprises a first electrode and a second electrode which are oppositely arranged; and a first light-emitting layer and a second light-emitting layer which are arranged between the first electrode and the second electrode, wherein the first light-emitting layer is close to the first electrode and the component material of the first light-emitting layer includes a first primary material and a first secondary dopant, the second light-emitting layer is close to the second electrode and the component material of the second light-emitting layer includes a second primary material and a second secondary dopant, the first secondary dopant and the second secondary dopant are different in component, the thickness of the first light-emitting layer is greater than that of the second light-emitting layer, or the thickness of the second light-emitting layer is greater than that of the first light-emitting layer. The position of the light-emitting center can be flexibly adjusted by controlling the thickness of the first light-emitting layer and the second light-emitting layer so as to control the efficiency and the life of the device and avoid the change of light color, brightness and color cast.
Description
technical field [0001] The present invention relates to organic light-emitting display technology, in particular to an organic light-emitting display device, a manufacturing method thereof, and an organic light-emitting display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device is a self-luminous display device with an organic light-emitting layer located between the cathode and the anode as the illuminant. It has ultra-thin, high brightness, high luminous efficiency and good shock resistance. Advantage. The constituent materials of the organic light-emitting layer usually include a host material and a guest material. After a voltage is applied to the cathode and anode, the triplet exciton energy of the host material is transferred to the triplet exciton energy of the guest material, thereby realizing electroluminescence. [0003] In the organic light-emitting layer of the existing organic light-emitting di...
