lcd screen bubbles in stock
I was able to plug this old LCD into a TV, which I think it"s 720p only because it worked with the 1366x768, and when changed to 1920 the image was worse. At 1366 all icons filled the screen, so a better TV would be suitable for Windows 10. The image doesn"t present any sign of bubbles, so it"s OK.
I think there are bubbles under my screen, i just got it (monday) and im really frightend, is it dangerous? is it bad for the monitor? i tried pushing around them but it wont work, i think its bubbles because when i try to wipe them they come back after 5-10 seconds. it doesent make any picture/game/video look blurry or anything like that. the monitor is a LG 34UC88-B. appreciate any help!!
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.
I have taken off the film over the front of the LCD. I have checked behind the LCD to see if any dirt or anything is stuck behind it, and also the metal plate also, but nothing is there.
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.
