Embodiment 1

[0041] figure 1 Schematic diagram of the structure of the module provided for the embodiment of this application Figure 1 . Such as figure 1 As shown, the module 100 provided by the embodiment of the present application includes: a first sub-module (B1 in the figure), a second sub-module (B2 in the figure), and a third sub-module (B3 in the figure).

[0042] Wherein, the second sub-module and the third sub-module are respectively located on both sides of the first sub-module; the film layer in the first sub-module, the film layer in the second sub-module, the film layer in the third sub-module The film layers of the second sub-module and the third sub-module are set in parallel to each other; the composition parameters of the second sub-module and the third sub-module are used to make the stress neutral layer of the module 100 and the stress neutral layer of the first sub-module meet the position coincidence condition.

[0043] In the embodiment of this application, please...

Embodiment 2

[0075] The embodiment of the present application also provides a module, which may include at least five sub-modules, the first sub-module, the second sub-module, the third sub-module, the fourth sub-module, and the fifth sub-module group, wherein each submodule may include at least one film layer. The composition parameters of the outermost submodule can be used to make the stress neutral layer of the whole module combined with the submodules of other submodules except the outermost submodule The position coincidence condition is reached.

[0076] In the embodiment of the present application, each film layer may be bonded by an adhesive layer. When the composition parameters of the film layer in the outermost submodule have been determined, the composition parameters of the adhesive layer in the outermost submodule can be set so that the stress neutral layer of the entire module is consistent with The stress-neutral layers of the sub-module combinations of the other sub-mod...

Embodiment 3

[0082] The embodiment of the present application also provides a module, which may include at least three sub-modules, for example, a first sub-module, a second sub-module and a third sub-module located on both sides of the first sub-module . Each sub-module respectively includes at least one film layer. The various film layers in the module can be bonded by an adhesive layer. Wherein, the number of stress-neutral layers of the module can be multiple.

[0083] In the embodiment of the present application, the number of stress-neutral layers of the module may be the same as the number of sub-modules in the module, or may be different from the number of sub-modules. When the number is the same, the stress-neutral layer of the module corresponds to the sub-module; when the number of the stress-neutral layer of the module is different from the number of sub-modules in the module, each stress neutral layer The neutral layer is respectively corresponding to at least one sub-modul...

Abstract

The invention provides a display module and an electronic terminal. The display module comprises a first sub-module, a second sub-module and a third sub-module, and the second sub-module and the third sub-module are bonded to the first sub-module. The film layers in the first sub-module, the second sub-module and the third sub-module are parallel to one another; and the composition parameters of the second sub-module and the third sub-module are used for enabling the stress neutral layer of the module and the stress neutral layer of the first sub-module to reach a position coincidence condition. According to the technical scheme provided by the invention, the testability of the bending performance of the display module can be improved.

Description

technical field [0001] This application relates to the field of modules, in particular to display modules and electronic terminals. Background technique [0002] With the continuous development of material technology, the application of modules is becoming more and more extensive. In order to meet the needs of various practical applications, the structure of the module is becoming more and more complex, and the reliability of the module has gradually become a key issue that needs to be considered in the application of the module. [0003] The module usually includes multiple film layers with multiple functions, and the film layers are bonded by adhesive layers. When the module is subjected to a bending test, the film layers in the module may break and other problems. [0004] At present, in order to meet the bending performance target of the module, it is necessary to conduct bending tests on modules with various components to determine the appropriate composition, which re...
