Embodiment Construction

[0047] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0048] Due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility, OLED display devices have gradually become the mainstream in the display field and are widely used in terminal products such as smartphones, tablet computers, and TVs. Among them, flexible OLED products are the most prominent, because they can meet various special structures and become the mainstream of OLED display.

[0049] With the development of flexible display technology, OLED products have gradually transitioned from bending and bending to elastic flexibility. Flexible and stretchable OLED display substrates have attracted extensive attention in the market due to their broad application space. Such as figure 1 A...

Abstract

The invention provides a stretchable display substrate and a manufacturing method thereof, a display device and a working method, and belongs to the field of display technology. Wherein, the stretchable display substrate includes a plurality of islands distributed in an array on the base substrate and separated from each other, and a plurality of connecting bridges connecting each of the plurality of islands, so An electrical detection structure is provided at the junction of the island and its adjacent connecting bridge, and when the stretchable display substrate is stretched, the electrical parameters of the electrical detection structure change. The technical solution of the present invention can improve the display effect of the stretchable display substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stretchable display substrate and a manufacturing method thereof, a display device and a working method. Background technique [0002] Organic Light-Emitting Diode (OLED) has gradually become the mainstream in the field of display due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. Terminal products such as smartphones, tablets, and TVs. Among them, flexible OLED products are the most prominent, because they can meet various special structures and become the mainstream of OLED display. [0003] With the development of flexible display technology, OLED products are gradually transitioning from Bendable, Foldable, and Stretchable. Flexible and stretchable OLED display substrates have attracted widespread attention in the market due to their broad application space, but there are still many technical problems to be solve...
