Abstract

The invention relates to an organic light emitting display device and a manufacture method thereof. The method includes providing an LTPS substrate; forming an anode layer on the substrate; forming an organic light emitting layer on the anode layer and forming a cathode layer on the organic light emitting layer, wherein the organic light emitting layer is used for emitting blue light; forming a quantum dot layer including red sub pixels, green sub pixels and blank sub pixels on the cathode layer; and forming a packaging layer on the quantum dot layer. Through forming the quantum dot layer on the cathode layer directly, through exciting the red sub pixels and the green sub pixels of the quantum dot layer with the blue light emitted by the organic light emitting layer and through penetration of the blue light by the blank sub pixels, light of different colors is emitted. Color saturation and color gamut are improved effectively. Besides, cost is reduced effectively and production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of organic light emitting technology, in particular to an organic light emitting display device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) is a promising flat-panel display technology with excellent display performance, such as active light emission, high luminance, high color purity, wide color gamut, and fast response speed. , low energy consumption and flexibility. [0003] In order to achieve full-color OLED display, the production of OLED devices currently uses Fine Metal Mask (FMM) technology, but the production cost of FMM is very high, and its life is short. damage. In addition, the alignment accuracy of the FMM and the backplane glass is very high, so as to ensure that the RGB pixels will not mix colors. However, the sagging of the FMM and the glass substrate is different, which leads to the inability of the FMM and the glass substrate to f...
