The substrate exposed suitable for the frame glue layer of narrow frame product
Technical field
It the utility model is related to display technology field, more particularly to field of display, and in particular to produce suitable for narrow frame
The substrate of the frame glue layer exposure of product.
Background technology
After 2014, narrow frame display is propagated its belief on a large scale, and nowadays this trend can be described as throughout each display field.
Mobile phone also popular narrow frame, TV also popular narrow frame, even lagging the notebook computer of development always, also occurs
The product of narrow frame.
For narrow frame for the quality-improving of product, it is also obviously that it, which is acted on,.When narrow frame can allow product more
Still, this is most intuitively to act on.Using the display product of narrow frame design, the utilization for size advantageously, same chi
Very little (including outer rim), the product screen display area of narrow frame is bigger, for notebook and mobile phone, it is meant that smaller
Fuselage, bigger size.
For the display of giant-screen, the makings lifting of product, have for the user to follow the fashion and very
Meaning.
The narrow frame design of currently available technology is that frame glue (Sealant) is designed on light shield layer (BM), due to BM sheets
Body is light tight, and this can cause the adhesive force of frame glue or intensity deficiency, therefore use in the prior art in TFT glass (also known as T sides
Glass) correspond on the position of frame glue, metal level is changed to slit design by whole maskings of script, and by script by CF glass
(also known as C sides glass) side Exposure mode is changed to T sides glass exposure mode, to ensure the design of frame glue by above-mentioned design method
Intensity can be identical with expection.However, this design method need by C sides glass turning could by T sides glass to be exposed,
It is unfavorable for the raising of production efficiency.
Utility model content
