Benefits of technology

This patent describes a solution to protect display screens from damage caused by external forces. The solution involves directly creating a protective film that acts as a buffer and barrier for water and oxygen, and attaching a cover to it to ensure a tight seal on the display module. This approach reduces the risk of screen breaking and improves the overall strength of the display device.

Problems solved by technology

In the conventional methods of manufacturing display screens, two glass substrates are configured to fix and encapsulate display components; since the relative motion of the two glass substrate is limited when the display screen is suffered from the external force caused by falling down and so on, while the glass substrate itself is easy to be broken and has a weak capability to resist against the external force, therefore the entire manufactured display screen is easy to be broken due to inner stress and other factors when operating, even the encapsulation failure or glass breaking may happen, thus it greatly reduces the structural strength of the device as a whole.
Since the above-mentioned glass substrate 11 and the encapsulation glass 14 are fixed and attached through the encapsulation material 13, when the display screen is suffered from the external force caused by falling down and other motion, the display screen is easy to be broken (and even crush) due to the aggregating of inner stress, thus the entire device structure may be damaged.

Abstract

The invention provides a display structure and manufacturing method of a display device, and relates to the field of display device technology. By forming a complex encapsulation film with the function of buffering and water-and-oxygen barrier on a display module directly, and attaching the cover on the complex encapsulation film, so as to ensure the sealing effect of the display module, and to efficiently prevent the display screen from breaking caused by the stress concentration generated by impact of external forces, thus the probability of breaking of display screen can be reduced effectively, and the structural strength of the display device as a whole is greatly improved.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to and the benefit of US Provisional Application No. 62 / 154,866, filed on Apr. 30, 2015, the entire content of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to the field of display device technology, more particularly, to a display structure and manufacturing method of a display device.[0004]2. Description of the Related Art[0005]The display screen is an important element of the display device, the structural strength thereof may directly effect how the entire display device is affected by the external force. Especially, with respect to the current mobile devices (such as smart phone, tablet etc.), the display screen thereof functions as the main interface of users operation, and would directly determine whether the entire device is able to be operated.[0006]In the conventional methods of manufacturing display screens,...
