Abstract

The present invention provides a method for manufacturing a display panel, comprising: forming a plurality of backlight units on a process substrate; filling partition walls between adjacent backlight units, and the height of the partition walls relative to the process substrate is greater than the The height of the backlight unit relative to the process substrate; a filter layer is prepared on the surface of the backlight unit away from the process substrate to obtain the backlight unit with the filter layer on the surface; wherein the filter The sum of the height of the layer and the backlight unit relative to the process substrate is less than or equal to the height of the partition wall relative to the process substrate; Peel off and transfer to the target substrate; package the target substrate. The invention can effectively improve the display effect of the display panel, reduce material waste and improve production efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a display panel. Background technique [0002] At present, display panels have been widely used in many fields such as portable electronic devices (such as mobile communication terminals, tablet computers, e-books, and navigation equipment) and large-screen electronic devices. Wherein, the display panel can be divided into a photoluminescence display panel and an electroluminescence display panel according to its light emitting principle. In recent years, photoluminescent display panels using quantum dots (Quantumdots, QDs for short) light-emitting materials are more and more widely used. Quantum dot luminescent material is a new technology applied in the field of display panels. The quantum dot luminescent material obeys the quantum size effect, and its properties change with the size of the quantum dot. When stimulated by light or electricity, the quan...
