lcd screen bubbles factory

LOCA, used during the building of LCD displays, are the industry standards for assembling displays within certain size ranges and for particular end uses. They are commonly used in high-demand, mid-sized monitors in automotive and aerospace applications, among others.

For each of the causes noted for bubbles in LOCA, there exists a corresponding set of solutions or proper behaviors that can minimize or eliminate it.

Choice of a low-shrinkage material -- High shrinkage of the adhesive layer after application can result in the development of voids, which can appear as bubbles.

The big bubble is adjacent to the edge and might indicate air leaking in, but not the small bubbles. An autoclave will not help with the small bubbles, and the big bubble will need re-gluing, which is rather complicated

Pressing will not help, as at least one upper layer glued to the LCD is hard. Repairing is a time-consuming job that requires separating and replacing however many layers are glued to the LCD screen, and damage can easily happen.

Most repairmen will prefer just replacing the screen, as the above can take hours and a mistake may be fatal to the LCD. You might be able to find a cheap replacement screen on Alibaba or similar.

What your picture looks like is that something has gotten in between the glass and the LCD. You could probably fix it by opening the device and cleaning/re-seating the LCD against the glass.

As to how did it happen, difficult to say. Possibly what ever glue or mechanism that holds the bottom of the LCD to the glass has come loose. Maybe from impact/shocks or just age. If it"s fairly new, then I would start thinking about manufacturing errors.

There’re more than 300 procedures to produce TFT LCD. The most advanced LCD, in which the array and cell process are highly automatic. Technically, every step in the process can lead to defects, and most of the defects have been eliminated through the development of TFT LCD technology.

In the LC filling process, if the quantity of LC injected is not enough, the spare space will form bubbles. And loose LC containing sealant will result in LC leakage.

Point defect is a kind of defect that some point on your screen don’t display correctly. There are mainly three situations: the point keeps displaying black or whitewhen the screen is working or the point can only display a single color.

In LCD, newton’s rings may occur on screen when two glass substrate haven’t been sealed well, so that one of the glass may form a convex lens and lead to light interference.

You may notice there are some screens have uneven display, which means some white area appears in dark picture or vice versa. We call this ‘mura’, a word originated from Japanese.

Mura is very common but it doesn’t affect the screen function severely, however it still bring bad look. Hence, many high end display manufacturers have their own standards of mura, and the displays without mura are of the best quality.

But now after using it 5 weeks without moving the laptop today a new tiny bubble appeared in the left top corner again. So I do not if to call them right away or waiting a little bit until a second one will appear. But I had the same problem as you when I found the bubbles the first time. Found nothing on the web. And sorry for my english, because i am from Germany and by the way I used the German support Team. And do not forget to tell them that you have a XPS laptop. Then this Supportteam can help you with your Adamo. They are also responsible for Adamo laptops.

(One Drop Filling) high quality displays can be produced. However micro bubbles can arise during this procedure. The micro bubbles are not visible directly after the ODF process,

but visible bubbles can be formed after some time. Using an autoclave can ensure, that no visible bubbles will be formed later and therefore quality and lifespan of the LCDs is increased noticeably.

In Union Repair store, we grade our iPhone screen into 5 different types of quality on the basis of different material assembled. The following is the full details of each condition.

It is with widely accept major complaint replacements for original parts, which keeps a right balance between price and quality.

By comparing the brightness and sharpness of the LCD, we found JK is the best quality among them and the second best is AUO. No doubt, the other components on the screen are all copy.

It is better than After Market Basic cause it comes with original laminated flexes and the LCD panel. Other components like touch panel, frame(hot pressed), backlight, polarize lens, and OCA is all copy from different factories.

The core components (like LCD and flexes) is 100% original pulled from used iPhone while the frame and touch panel is copy. The touch panel and frame come together with cold pressed glue and assembled together with the LCD by the capable third-party factory which keeps its excellent quality.

No doubt, it is tear down from used iPhone with all the parts 100% original and working perfectly just like an original new screen, it has whatever the original new screen has. The only complaint about this quality is that some of the displays are with 1 or 2 scratches but still be welcome by our critical customers who are requiring good quality.
