These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0024] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0025] In the related art, the display area of a display screen is often smaller than the size of OCA solid optical glue, and the effective area of OCA solid optical glue bonding depends on the size of the upper glass substrate. However, when the upper glass substrate is small and the size of OCA solid optical glue is the same as the size of the upper glass substrate, bubbles at the edge of OCA solid optical glue can be seen from the edge of the ink on the cover plate, thereby affecting the user's viewing experience.
[0026] In view of the above problems, an embodiment of the present application provides an OCA full-fit structure, which can extend the OCA solid optical adhesive and avoid bubbles at the edge of the OCA solid optical adhesive being seen from the edge of the ink, thereby improving the viewing experience.
[0027] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0028] See also Figure 1 and Figure 2 An OCA full-lamination structure includes: a cover plate 100, an adhesive component 200 and a display component 300, the adhesive component 200 includes an OCA colloid 210 and an OCA colloid extension 220, the OCA colloid 210 and the OCA colloid extension 220 are respectively arranged on the cover plate 100, and the OCA colloid 210 is connected to the OCA colloid extension 220; the display component 300 is arranged on the OCA colloid 210.
[0029] It should be noted that the width of the OCA colloid extension 220 is 2 mm, so that the overall length of the OCA colloid 210 is longer than the display area 400 , and the user cannot see the edge bubbles of the OCA colloid extension 220 from the ink edge on the cover plate 100 , thereby improving the viewing experience.
[0030] See also Figure 3 In one embodiment, an ink screen printing area 110 is provided on the cover plate 100. It should be noted that the ink screen printing area 110 is located at the periphery of the cover plate 100, which plays a shielding role.

Specifically, the display assembly 300 includes an upper glass substrate 320, which is disposed on the upper polarizer 310. Specifically, the display assembly 300 also includes a lower glass substrate 330, which is disposed on the upper glass substrate 320.
