What Are the Technical Difficulties in the Production of Cob Packaged Display

Because the manufacturing of cob packaging display screen is different from SMD packaging display screen, it realizes the smaller dot spacing of LED display screen, so cob packaging display screen is more popular in some cases. Therefore, due to the market demand, cob packaging display manufacturers also came into being.

The conditions for producing cob display screen are harsh. The packaging methods are different, and the production process of conventional SMD packaging cannot be directly applied. For LED display manufacturers, if they want to transition to the production of cob display, the cost is very high, and the technology also needs to be developed and improved.

Secondly, although the cob display has been improved for several rounds and the ink consistency has been improved, the technology also has requirements. In addition, the technology of cob display manufacturers has not been well communicated and popularized, which is very difficult. Most cob display screen projects are mainly bidding, which is about differentiation. Even the small spacing of conventional SMD requires bid control conditions in bidding, not to mention the closed cob display screen.

Moreover, at present, the number of manufacturers of cob packaged display screen is very small, and it is not easy for LED display screen manufacturers without certain scale and conditions to transform. At present, the domestic well-known manufacturers of cob packaged display screen should be HIDA and Lehman. Of course, in addition to cob display screen, there are other types of LED display screen that can be made with ultra-small dot spacing, such as mini and micro.

The mini LED display screen is OK, and the original packaging method is retained. In this way, the LED display screen manufacturers do not need to transform and can produce directly; Micro focuses on the field of wearable and home TV; Cob large screen focuses on various indoor use environments: conference room, energy, regulation, security and other field centers. Of course, cob TV is also available.

Although these products are different, when necessary, these displays can collude in various fields, but specific ones are more suitable. Dayuan intelligent cob display has various models and perfect qualifications. It can assist in cob all-in-one TV or cob large screen bidding projects.

What Are Some Ways to Keep My Hair Really Healthy?
Use professional shampoo & conditioner. I know it may seem like a rip-off, however all the shampoos like Pantene, Garnier, etc. have a high alcohol content....since the normal pH of your hair is 4.5-5.5, things containing high amounts of alcohol throw your hair all out of whack and cause breakage, split-ends, fly-aways, etc. The reason these shampoos make your hair feel soft is because they contain high amounts of humectants, which are just a cover for how damaging they really are! Another tip is ALWAYS use a thermal protector while applying heat. Heat appliances cause tons of damage to your hair. Usually this is a cream/clear gel you apply before blow drying. Never use a flat iron on hair that is not completely dry!1. Split End Help. ( 10 Points) !!!!!!!!!!!!!!!!!!!!!!?For sure you should get a trim and maybe even cut your hair as short as you are comfortable doing it. You should for no reason straighten or dye your hair. Look for some Garnier Fructis or Pantene shampoos and conditioner for curly hair so that it extra moisturizes it and helps the split ends repair themselves. I say from experience that ppl with curly hair have really bad split ends, which is why we have special stuff in our hair products. The split ends wont magically go away in like a month or a few weeks, but you will see improvement after a while. Oh, and for sure DO NOT PICK THEM OFF!! It will just make it worse. Every two months until your hair is healthy get a trim. just maybe half an inch or an inch will be just fine. Eventually your hair will go back to normal. Good luck with that!.2. Whats the best shampoo conditioner for cheap?clever or V05 are solid inexpensive ($a million) shampoos, yet whilst it is composed of conditioner i could bypass Tresemme ($6) it does an somewhat solid interest. i take advantage of salon shampoo because of the fact i am form of a hair snob, yet I nonetheless use the cheap conditioner. Pantene is undesirable on your hair (too plenty protein and reasons alot of greater build up on the hair) so i does not bypass there. desire this permits! My hair is oily, superb, and colour-taken care of if that helps you any!3. How can I get my curly hair to be nice like Taylor Swift?Haha i have the same hair long and curly..but not pretty curly! im completely obsessed with taylor and her hair so i did so playing with it and what you really NEED to get is the conair hot sticks!! they are these little flexible curlers and they are not very expensive and i would look like a frizz ball without them!! you can like get them at walmart. anyways what i do when iwear my hair curly is like i get up and get in the shower and wash it and condition it and this may sound weird but dont use a whole lot of conditioner just enough to get it done cause it will help your hair hold the curl the just get out and towel dry your hair till it is just damp and then put a curling mouse in it and frizz serum then finish blow drying it straight! and you know have the curlers on like when your gettin in the shower and then just make sure the little light is on meaning that they are hot enough and then seperate your hair into pretty small peices (if you have really thick hair then you might need to buy two sets cause they only have 14 in them and you use small sections) and then start from the botom of your hair and role it through your hair and pin it together youll see the instructions on how to pin them together and make sure you wrap it all the way to the top of your head and leave them for like 15 or 20 minutes while your finishin gettin ready and then use like a light hairspray about 5 minutes before you take them out then your done. i know this thing was really long but its not that hard lol!!!! hope i helped good luck!!!!!!!!
