Problems solved by technology

However, such a special package will inevitably increase the production cost of the quantum dot film and the corresponding process difficulty
In addition, epitaxial technology generally requires relatively expensive equipment, and the process is relatively complicated, so it is not suitable for large-scale industrial production
To sum up, the processing methods for quantum dot materials in the prior art, on the one hand, are likely to cause degradation phenomena such as agglomeration of quantum dot materials, and on the other hand, they are accompanied by special packaging processes.
These two not only are not conducive to the improvement of the display quality of quantum dot display devices, but also increase the related manufacturing cost and process difficulty

Abstract

The invention relates to the technical field of quantum dot displaying and discloses a method for manufacturing a quantum dot display device. The method comprises: providing an array substrate and a butting substrate facing each other; printing alignment solution containing quantum dot material to one side of the array substrate which faces the butting substrate; removing a solvent in the alignment solution printed to the side of the array substrate which faces the butting substrate; after the solvent is removed, heating the array substrate; providing a backlight module on the side of the array substrate which is opposite to the butting substrate. The invention also discloses a corresponding quantum dot display device. By the aid of such manufacturing method, the display quality of the manufactured quantum dot display device is greatly improved, and related manufacture cost and process difficulty are decreased.

Description

technical field [0001] The present invention relates to the technical field of quantum dot display, and in particular to a method for manufacturing a quantum dot display device and a corresponding quantum dot display device. Background technique [0002] With the rapid development of the display field, quantum dot display technology has attracted more and more attention due to its unique luminous properties, excellent stability, wider color gamut coverage, and relatively low cost. Currently, in display devices using quantum dot display technology, the blue light emitted by the backlight is usually used to excite the quantum dot material to emit red light and green light, thereby providing color display. In essence, a quantum dot display device is a device that realizes color display by means of the backlight source and the photoluminescence effect of quantum dot materials. [0003] In the existing quantum dot display devices, the quantum dot material is usually made into a ...
