Problems solved by technology

Although the thermal properties and barrier properties of glass substrates are relatively excellent, their mechanical properties are poor and are not suitable for flexible displays; although metal foil substrates can be bent, their surface roughness is large, and electronic devices will fall off when mechanically bent; Polymer substrates have good flexibility, but compared with glass substrates and metal foil substrates, there is a problem of poor thermal stability. When making low-temperature polysilicon LTPS, the process temperature is as high as 300-500 ° C, and the resistance to polymer substrates Heat puts higher demands on

Abstract

The invention provides an ultrathin LED flexible display screen which comprises a display module and a drive control device, and the display module is connected with the drive control device through adata line. The display module sequentially comprises a supporting layer, a first energy absorption layer, a driving connection layer, a second energy absorption layer, an LED array layer, a thin filmpackaging layer, a third energy absorption layer, a light polarization layer, a fourth energy absorption layer and a panel protection layer from bottom to top. According to the flexible display screen, the energy absorption layers are arranged, so that the high-elasticity and high-extension energy absorption layers are arranged among all the layers, when the shape of the flexible display screen is changed according to requirements of a user, stress gathered on all the functional layers of the flexible display screen can be effectively released by means of the energy absorption layers, and therefore normal work of the flexible display screen is guaranteed.

Description

【Technical field】 [0001] The present application relates to the technical field of LED display devices, in particular to a flexible LED display screen. 【Background technique】 [0002] Generally, as examples of the display device, an organic light emitting diode LED display, a liquid crystal display LCD, and a plasma display panel PDP are generally included. Wherein, the organic light emitting diode display includes a substrate and an organic light emitting element. [0003] In recent years, the application of rollable organic light-emitting diode displays has become more and more extensive. It is a rollable display (hereinafter referred to as flexible display), including the use of flexible display substrates. However, rollable organic light-emitting diodes The display screen is susceptible to external influences, such as extrusion, impact, friction, etc., and is very easy to damage, which also puts forward higher requirements for flexible display substrates. As the basic ...
