Embodiment 1

[0047] This embodiment provides a cover plate of a display device, the cover plate is arranged on the display side of the display module for protecting the display device of the display module, the cover plate includes a substrate and an ink layer on the surface of the substrate, The frame area on the side of the substrate facing the display module is a concave portion relative to the visible area on the side of the substrate facing the display module; the ink layer completely covers the concave portion facing the display module The surface on one side of the group.

[0048] The specific shape of the cover plate is not limited in this embodiment, and the cover plate can be divided into a double-plane cover plate, a single arc-surface cover plate and a double-arc-surface cover plate according to whether its surface is a plane or an arc surface. It should be noted that the cover plate has relatively high transmittance, and can protect and support the internal structure of the di...

Embodiment 2

[0066] The general production method of the cover glass in the prior art includes: cutting / cutting-edge / forming-beveling-polishing-surface tempering-screen printing-coating-inspection-packaging and other steps, specifically:

[0067] Cutting / cutting: Cut the whole piece of glass into glass blocks larger than the product required by the customer, and then transfer to the next process for production;

[0068] Edge turning / forming: shape the material from the cutting process, and process it into a shape consistent with the drawing provided by the customer;

[0069] Edge chamfering: edge grinding is carried out on the products completed by the edge turning process, and meet the requirements of appearance and performance according to customer requirements;

[0070] Polishing: to meet the surface finish requirements of the finished product, and to control the thickness requirements of the glass;

[0071] Surface toughening: strengthen the polished products to improve the surface ha...

Embodiment 3

[0082] This embodiment provides a display device, such as Figure 9 As shown, it includes a cover plate 91, an adhesive layer 92 and a display module 93. The cover plate 91 is located on the display side of the display module 93, and the cover plate 91 and the display module 93 are bonded through the adhesive layer 92, that is, glued together. The adhesive layer 92 is located between the bonding surface 91A of the cover plate 91 and the display surface 93A of the display module 93 , and bonds the cover plate 91 and the display module 93 correspondingly. The cover plate 91 in this embodiment can be any one of the cover plates in the previous embodiment.

[0083] It should be noted that the preferred cover plate in this embodiment is the one in the previous embodiment Figure 4 cover plate shown, Figure 4 In the cover plate shown, the height of the ink step is 0, so that the adhesive layer can be fully bonded to the cover plate during the lamination process of the cover plate...

Abstract

The invention provides a cover plate, which is arranged on the display side of a display module and comprises a substrate and an ink layer, wherein the ink layer is positioned on the surface of the substrate; a frame region of the substrate facing one side of the display module is a concave part opposite to a visible region of the substrate facing one side of the display module; and the ink layer is formed on one side of the concave part facing the display module and fully covers the surface of the concave part facing one side of the display module. Since the substrate of the frame region on the substrate is the concave part opposite to the substrate of the visible region, a formed ink step has smaller height than the ink step in the prior art or the formed ink step moves to the frame region after the ink layer with the same thickness as that in the prior art is formed on the concave part; and thus, the influence on the display quality of the visible region of a product is smaller, and further the yield of the product is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of flat panel display, and more specifically, to a display device and a cover plate thereof. Background technique [0002] With the development of science and technology, more and more electronic products appear in people's lives, from small products such as mobile phones, personal digital assistants (Personal Digital Assistant, PDA), digital cameras, e-books, to large products such as POS (point of sale Sales terminal) systems, public inquiry systems, portable computers and other electronic products have gradually become necessities in people's lives. In the above electronic products, regardless of the touch device or the non-touch device, there is a cover on the outside. [0003] Usually the cover material is glass, so the cover is also called cover glass. Cover glass is protective glass, usually called coverglass, or coverlens. Cover glass is an important component of the display device. Its mai...
