Title:
DISPLAY SCREEN AND PREPARATION METHOD THEREFOR, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/178782
Kind Code:
A1
Abstract:
Disclosed by the present application are a display screen and a preparation method therefor, and a mobile terminal, the display screen comprises: a transparent substrate, a thin film transistor layer, a positive pole layer, a luminescent layer, a common layer and an encapsulating film layer that are stacked; the common layer comprises at least one layer of layer structure, and, for each layer structure, includes a first portion and a second portion that are splicing. When preparing the display screen, a first hole or a fourth hole penetrating through the thin film transistor layer, the positive pole layer, the luminescent layer and the common layer is formed, and when the first hole or the fourth hole is formed on the common layer, the first hole or the fourth hole is located at the splice of the first portion and the second portion on each layer structure. The transparent area in the present application comprises layers which are merely the substrate and the encapsulating film layer, which reduces the arrangement of the transparent area layer structure, and thereby improving the light penetration rate, reducing the light loss when the light penetrates the transparent area and enhancing the light transmission effect of the display screen. Moreover, according to the solution, the encapsulating film layer encapsulates the gaps between the layers on the sidewall of the first hole or the fourth hole, and thus improves the anti-water and oxygen erosion effect of the display screen.
