TDM full fit content and precautions

A high-tech company engaged in the research and development of full-fit materials in the optoelectronic industry, with its own core technology patents of polymer organic nano-silicon materials (including formulations and production processes) and automated full-fit equipment, has researched and developed a series of AB two-component organic silicone and supporting full-fit equipment, it is a solution for photoelectric manufacturing enterprises, especially touch module full-fit enterprises, TP/LCM module full-fit enterprises and protective cover plate (AG/AR) full-fit enterprises.

From the structure of the screen, we can roughly divide the screen into three parts, namely, the protective glass, the touch screen and the display screen. However, these three parts need to be bonded. According to the bonding method, they can be divided into three types: full bonding, frame bonding and 0 bonding.

The bonding process refers to a bonding manner between the cover plate and the liquid crystal display module, and full bonding has been basically adopted in the industry at present. According to different positions and different sizes, there will be some different choices.

With the increasingly fierce competition in the mobile phone screen manufacturing industry, if you want to occupy a position in the market, you must continue to improve the process to increase the yield and reduce costs. As the mainstream process of mobile phone screen assembly, "full fit technology" needs continuous improvement. In the mobile phone screen assembly process, the full bonding process has become the mainstream technology, and combined with In-Cell, On-Cell, OGS and other technologies, the display effect of the produced touch display screen is significantly improved. Since it is only necessary to use the liquid glue to bond with the single glass once, the material cost is saved, the production process is simplified, the product is significantly thinner and lighter, the transmittance is enhanced, and the display effect is significantly improved. The smart phone produced by the full fit technology brings users a better use experience.

There are generally two types of touch bonding methods: full bonding and frame bonding. Full bonding is performed by water glue bonding with a fully automated machine. Its advantages are better display effect and dustproof, while frame bonding is stronger and each has its own advantages. Use different industries, so pay attention to the bonding method.

For non-touch screens, the increase in cost of choosing full fit is obvious, and only Apple has insisted on using full fit. In addition to cost and yield, the reason is probably related to the selling point that the combination of full-fit screens will not increase the parameters. I believe that users who have come into contact with full-fit screens will find the advantages of full-fit screens in terms of beauty (integrity), durability (scratch resistance), etc.

The bonding is carried out by using OCA optical transparent adhesive tape or substrate-free optical transparent adhesive tape. Simply put, it is carried out by using transparent adhesive tape with high permeability. At present, it is widely used in touch screens of consumer electronic products such as smart phones and tablets, so as to realize the bonding of the three parts of the touch screen, the protective glass, the touch screen and the display screen.

What's more, the full-fit technology is basically the same as that of bare metal. In terms of display, both color and brightness are not affected at all, and there is no problem with touch control. The touch screen is very sensitive.

The joint innovation 27P1U has several points that I like, especially for several parameters used by designers. Compared with the ordinary display frame pasting process, the joint innovation 27P1U display adopts a full-fit manufacturing process. The full-fit technology enables the integrated screen to display the same transparent effect whether it is a front visual effect or a side view. At the same time, it has anti-scratch and anti-collision features, dustproof and other advantages.

The film sticking tool sent to you is in place. The film sticking positioning artifact (positioning film sticking angle) scraper (removing air bubbles from sticking to the edge) is baked with a light box (the reflected light of the light box makes the edge of the film fully covered and baked), so that the crystallized film is firmly welded to the screen without slipping off.

As all the old fans know, the previous M-series tablets used non-full-fit screens. Only the T-series tablets used full-fit screens. This M40Air is an M-series tablet computer with full-fit screens.

Adhesive film: The traditional UV full adhesive film requires glue to be dropped on the screen and then cured by a baking lamp to make the toughened film completely fit. However, the amount and uniformity of glue are not well controlled during the film sticking process, and most people will block the receiver and affect the sound outside the mobile phone. Moreover, glue residue will also appear on the screen when the full adhesive film is torn off later.

The full-fit OCA can fill the gap between the touch display components and reduce double reflection, thereby enhancing brightness, improving contrast, improving outdoor readability, bringing clearer images, thinner screen size, and blocking water mist and dust.

In terms of elasticity and wrapping, it is also very thoughtful. The whole adopts the full-wrap compression design, which can bring the dynamic core compression experience of seamless fit. After wearing, it closely fits the skin, and the body can still fully stretch. Coupled with the special zonal tailoring, you can freely master the leg muscles, will not affect the leg and hip movement range, water movement unrestrained.

Recommended reasons: designed for small apartment research and development, smaller size does not occupy space, more comfortable and intimate. With ergonomic SL type guide rail, all aspects of your curve, give you the comfort of the whole body.

The main advantages of the film are reflected in the film sticking operation and the film sticking tools are in place, the film sticking positioning artifact (positioning film sticking angle) scraper (removing air bubbles from sticking to the edge), and the self-brought light box baking (the reflected light of the light box makes the edge of the film fully covered and baked), so that the crystallized film is firmly welded to the screen and the service life is much higher than that of the ordinary mobile phone film.

The bonding method is between full bonding and frame bonding, mainly filling a non-adhesive transparent medium with a refractive index equivalent to glass between the touch panel and the LCD screen. On the one hand, there is no gap between the touch panel and the LCD screen, which improves the display effect; on the other hand, because it has no viscosity, it is very simple to assemble and maintain, and the overall cost is low.

The pillow uses a full surface shape, arc design, can be a good fit to the shoulder and neck, to ensure sufficient support. 95% of the openings are very breathable in the memory pillow.

At the same time, there is another well-known change in mobile phone screens-full-fit screens have gradually replaced non-full-fit screen technologies, and the effect achieved is that the distance from the screen is visually reduced, and the middle is no longer felt. There is a protective layer. And the full fit screen, in the market at that time has also become a necessary purchase standard for many people.

At present, touch screens are very common in the market, but in actual use, some consumers say that touch screens are not sensitive, and situations such as Caton occur frequently. This is because some manufacturers' touch screen full-fit technology is not mature. So in the choice of manufacturers, we must consider this problem, so as to avoid some unnecessary losses.

The most surprising thing is its balance. Needless to say, the display effect is MacBook. The screen quality of the shoulder-to-shoulder screen makes me feel that there is no sense of fragmentation. Although it is not 4k, it does have a feeling. I guess it is also because the full-fit glass technology makes its display effect better.

Due to the use of a full-fit screen, the front is printed directly on the CoverGlass, and the visual perception is still good. However, the full fit also makes the 27P1U's border wider, which is wider than the current mainstream ultra-narrow border. The upper right corner of the front is an opening for the photosensitive sensor, which can turn on the light sensing function in the OSD, and the display will adjust the screen brightness according to the ambient light. However, my personal habit is to adjust the brightness slightly lower. If the official can upgrade the firmware later, it would be better to support the customization of automatic brightness adjustment.

Bailing series box-type, back-of-the-ear and standard ear canal-type standard silicone earplugs fit the ear canal, are skin-friendly and comfortable, and provide full-frequency amplification effect. Even if it is severe hearing loss, it can also meet the needs of hearing compensation.

However, the iPadAir5 is used with the second generation pen, which has a small voice and no sense of spacing when writing. The other second generation pen also solves the problems of inconvenient charging and storage of the first generation pen. The protective film on the full-fit screen will not affect its advantages.

The combination is a concept that began to rise in 2018 and has been successfully applied in some manufacturers. The bonding method is between full bonding and frame bonding, mainly filling non-adhesive transparent medium with refractive index equivalent to glass between TP and display screen. On the one hand, there is no gap between the glass and the display screen, which reduces diffuse reflection and improves the display effect; on the other hand, because it has no viscosity, it is very simple to assemble and maintain, and the overall cost is low. At present, the cost of 0 bonding on the market is less than 500 yuan (86 inches, for example, the maintenance cost is lower).

The difference in price will generally be reflected in the full water washing or fitting the face and the electricity quantity display. The others are usually bragging and don't use tubes very much. There is no full water washing around 59, usually around 99. Other brands are not necessarily. I have seen one that costs hundreds of dollars, and the more expensive one will be equipped with the electricity quantity display, more than 200 more than one point to more than 300 will generally be equipped with face fitting, in fact, there is a compressible glue or plastic under the cutter head to adapt it to your face.

On the 8th, we reached a strategic cooperation with the principle of complementarity, coordination and win-win, and strengthened the integration of supply chain resources, project development and development layout. The deputy general manager, general manager and Mr. chairman formally signed an optical full fit strategic cooperation agreement. Both leaders attended the signing ceremony.
