Embodiment 1

[0030] Such as figure 2 Shown is a schematic structural view of the substrate used to make a flexible display in this embodiment, including a supporting substrate 21 and a flexible substrate 23, and a bonding glue is arranged between the supporting substrate 21 and the flexible substrate 23 Layer 22, the bonding adhesive layer 22 is used to adhere the flexible substrate 23 to the supporting substrate 21, and the adhesive force of the bonding adhesive layer 22 changes with the ambient temperature. The bonding adhesive layer 22 is a temperature-controlling adhesive layer, wherein temperature control means that the adhesive force of the bonding adhesive layer will change when the ambient temperature changes.

[0031] figure 2 The preparation method of the substrate for making a flexible display shown in is as follows: firstly, take glue whose adhesive force changes with the change of ambient temperature; then apply the glue on the supporting substrate 21 to form a bonding glue...

Embodiment 2

[0040] Such as figure 2 Shown is a schematic structural view of the substrate used to make a flexible display in this embodiment, including a supporting substrate 21 and a flexible substrate 23, and a bonding glue is arranged between the supporting substrate 21 and the flexible substrate 23 Layer 22, the bonding adhesive layer 22 is used to adhere the flexible substrate 23 to the supporting substrate 21, and the adhesive force of the bonding adhesive layer 22 changes with the ambient temperature. The bonding adhesive layer 22 is composed of a temperature-controlled adhesive layer, wherein temperature control means that the adhesive force of the bonding adhesive layer will change when the ambient temperature changes.

[0041] Similar to Example 1, such as image 3 As shown, it is a schematic diagram of the method for preparing a flexible display in this embodiment, wherein the support substrate fixing device 31 is used to fix the support substrate 21, and then coat a layer of...

Abstract

The invention discloses a flexible display screen substrate. The substrate comprises a support base and a flexible base. An adhesive gel layer is arranged between the support base and the flexible base. The adhesive gel layer is used for pasting the flexible base on the support base. The adhesive force of the adhesive gel layer changes with the change of the environment. The invention further discloses a preparation method of the flexible display screen substrate. The method comprises the steps of firstly taking glues which have the adhesive force changing with the change of the environment, smearing the glues on the support base to form the adhesive gel layer. The invention further discloses a preparation method of a flexible display screen. According to the flexible display screen substrate and the preparation method thereof and the preparation method of flexible display screen, the environmental temperature is changed to achieve the detachment of the flexible base from the support base, the feature is different from the traditional laser detachment technology, and the damage caused by laser to the flexible base is avoided.

Description

technical field [0001] The invention relates to the field of flexible display preparation, in particular to a flexible display substrate and a preparation method thereof, and a flexible display preparation method. Background technique [0002] Flexible displays are also called bendable displays or soft displays. It is made of soft materials, and its main structure includes a flexible substrate, an intermediate display medium and packaging. [0003] Traditional flexible displays mainly use flexible substrates with a thickness of less than 100 microns, such as ultra-thin glass, stainless steel films, and plastic substrates, as flexible substrates. Due to the problems of fragility, wrinkling and deformation of the flexible substrate, in the actual production process, the flexible substrate is generally attached to the rigid substrate to complete the production of thin film transistor array, OLED production and packaging. The peeling method peels off the rigid substrate to com...
