Since Apple launched the first "alternative" smartphone in 2007, the large touch screen and high resolution have become the basic configuration pursued by major mobile phone manufacturers. Especially with the help of the Android system, smartphones have entered the era of configuration. As for the specific screen, due to the problem of the combination of the touch screen and the display screen, it will cause troubles in the mobile phone. I believe that early users of HTC G3 or MOTO Milestone 1 have a deep experience. In solving the above problems and in pursuit of a thinner mobile phone experience. As a result, touch solutions such as OGS, On-cell, In-cell, etc. have been launched one after another.
DisplaySearch analyst Yu Ningning believes that due to the huge influence of Apple and Samsung in the field of smart phones, In-Cell and On-Cell account for a relatively high proportion of mobile phone touch screens. However, due to the diversified needs of mobile phones, OGS touch screens with stable yields and reasonable costs still have a lot of room. Moreover, emerging touch notebook computers also mainly use OGS screens. So manufacturers like Skyworth and other LCM modules have accelerated the layout of OGS touch. Face the competition with panel makers involved in related fields, and strive to get a share of this big market.
Skyworth products
At the "Mobile Terminal New Technology and Supply Chain Exhibition 2013" held at the Shenzhen Convention and Exhibition Center early in the month, electronic enthusiasts had the opportunity to communicate with Song Xiang, director of the small and medium-sized business unit of Skyworth LCD (Shenzhen) Co., Ltd. Share some views on the industry.
OGS and On-Cell are the key
We know that in the production process of the initial mobile phone screen, the protective glass, touch screen and display screen were laminated twice. Among them, the use of frame stickers or full stickers will more or less affect the yield of the product. Therefore, the OGS full-fitting technology was launched with the touch panel manufacturer as the lead. The full-fit technology eliminates the air between the screens, which helps reduce the reflection between the display panel and the glass, which can make the screen look more transparent and enhance the display effect of the screen. At present, some mobile phones such as iPhone 4S, Mi 2, Nexus 7, Ascend D1 quad-core also use full-fit technology.
Comparison of ordinary fitting and full fitting
On Cell refers to the technical method of embedding the touch screen between the color filter substrate and the polarizer of the display screen, that is, adding a touch sensor to the LCD panel, there is no gap between the display screen and the touch screen, and it has ultra-high contrast , Has the advantage of a large viewing angle, the disadvantage is that the screen color display is too rich, the eyes may be a little tired for a long time.

Skyworth LCD, as a LCM module manufacturer specializing in 3.5-4.0 inches, also had OEM experience for Samsung and other large international companies. Now is involved in the field of touch control. Currently Skyworth has invested a lot of manpower and material resources in research and development. Engage the elites in the industry, and strive to develop better products.
According to Director Song, Skyworth LCD is currently doing better at OGS and is also specializing in on-cell modules. And there are currently two manufacturers applying their solutions. Considering that Skyworth LCM modules have been working with manufacturers such as Konka, Sang Fei and TECNO, if they can improve the yield. I believe that the follow-up plan is not a problem for Skyworth.
I asked whether there is cooperation with the four major domestic manufacturers such as "China Cool League". Director Song regretted to tell us that Skyworth has not directly cooperated with these four manufacturers. Instead, they have cooperation with their ODM vendors. Follow-up Skyworth hopes to cooperate with first-line manufacturers such as China Cool Alliance to improve their technological competitiveness and market competitiveness.
Talking about the current market turnover of Skyworth LCD, Director Song told us that the annual revenue of the Skyworth LCD department is about 100 million to 200 million, and the total revenue is expected to exceed 200 million by the end of this year. But relative to the revenue of LCD panel factories, this turnover is relatively small. When asked if Skyworth would be involved in the panel production business. Director Song's answer to us is that Skyworth will not invest in this industry at present.
Although the share is small, the experience has grown from scratch, relying solely on its own department to develop the market, rather than relying on the power of Skyworth Group. Skyworth LCD has taken its first successful step, hoping that domestic manufacturers can deepen their technology and bring better products to the industry chain. Thereby pushing the entire industry forward.
In-Cell is always a difficult point
Compared with On-Cell and OGS, the current application of In-Cell on Apple iPhone 5 is always a difficult point, which is a challenge for domestic manufacturers. In-Cell refers to the method of embedding the touch panel function in the liquid crystal pixels, that is, embedding the touch sensor function inside the display screen, which can make the screen thinner and lighter. At the same time, the In-Cell screen should also be embedded with the supporting touch IC, otherwise it will easily lead to erroneous touch sensing signals or excessive noise.
Comparison of In-Cell and ordinary touch
In-Cell, as the leading solution of panel manufacturers. For panel manufacturers, the technical demand is quite high, and it is also a big challenge in terms of product yield. As an LCM module manufacturer, Director Song introduced that Skyworth will cooperate with LGD in the near future to promote in-cell technology solutions. I believe that through cooperation with foreign high-tech manufacturers, Skyworth can benefit a lot from it.
Through cooperation with upstream panel manufacturers, open cell is introduced for packaging and reprocessing. Skyworth has cut into the small and medium-sized consumer market. Currently, it has launched 5.5-inch FHD and HD LCD screens. At this exhibition, we even saw more than 400ppi solutions launched by Skyworth. Although the current panel factory has also entered the field of touch, the touch industry and the panel industry are not exactly the same. Panel factories will only focus on large customers, while TP factories can target different customers, which is also a big market in China. Compared with manufacturers such as Skyworth, there is still great potential. Hope to see Skyworth and so on go further.
·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
