Embodiment Construction

[0036] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [up], [down], [front], [rear], [left], [right], [inner], [outer], [side], etc., are only for reference Additional schema orientation. Therefore, the directional terms used are for describing and understanding the present invention, not for limiting the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0037] Embodiments of the present invention provide a quantum dot ink, a method for fabricating a display panel using the quantum dot ink, and a display panel fabricated using the quantum dot ink. By adding blocking quantum dots to the quantum dot ink, the diffusion of the quantum dot ink in the inkjet printing process is suppressed, thereby eliminating the coffee ring effect of the f...

Abstract

The invention provides quantum dot ink, a display panel manufacturing method and a display panel. The quantum dot ink comprises an organic solvent and quantum dots dispersed in the organic solvent, and the quantum dots comprise light-emitting quantum dots and blocking quantum dots. According to the quantum dot ink, the blocking quantum dots are added into the quantum dot ink, so that the diffusioneffect of the quantum dot ink in the ink-jet printing process is inhibited, the coffee ring effect is prevented, the flatness and uniformity of a quantum dot film surface are improved, and the display panel shows excellent display quality.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a quantum dot ink, a method for manufacturing a display panel and a display panel. Background technique [0002] The quantum dot light-emitting diode display device is a self-luminous display technology that does not require a backlight. It not only has low energy consumption, ultra-thinness, wide viewing angle, strong color expression, wide operating temperature range, and easy implementation of organic light-emitting diode display devices. It has the advantages of flexible display and other advantages, and also has the advantages of narrower luminescence peak and higher color saturation, so it has a wide range of application prospects. [0003] Inkjet printing technology is a key technology in the manufacturing process of quantum dot light-emitting diode display devices. The uniformity of the quantum dot layers formed by inkjet printing technology directly affects the ...
