On cell touch technology is gaining market power in the smart phone market.
with the yield increasing and the price becoming more competitive.

On cell touch is booming: touch market pattern changes

bridge on cell and single-layer multi-point on cell touch solutions have won the favor of high-level and low-level smart phone manufacturers respectively, and expanded the introduction of their products, It is expected to further promote the penetration of on cell touch solutions in the mobile phone market.
bridge on cell (Figure 1) and single layer multi-point on cell touch solutions (Figure 2) are rapidly emerging.
panel suppliers rely on the technical support of touch chip manufacturers.
they have gradually overcome the obstacles of yield and cost development of bridge on cell and single layer multi-point on cell touch solutions, As a result, it has attracted the attention of medium and high-level, white brand and medium and low-level smart phone brands respectively, and is ready to greatly increase the proportion of adoption in the product line.

Samsung display, Youda, Qun Chuang, Huayin, Shenghua and other panel factories,We have actively developed a more cost competitive bridge on cell touch solution, and are expected to officially mass produce it in the second half of the year, It is hoped to reduce the development space of OGS in the middle and high-level smart phone market.
said Wang Jiayu, project manager of St analog and sensor technology marketing department.
thin film transistor liquid crystal display (TFTLCD) panel manufacturers are leading the development of touch panel industry of middle and high-level smart phones, making greater profits from it, and are joining hands with touch chip manufacturers to speed up the development of bridge The on cell touch solution has been put into production.
compared with OGS, which develops external touch panel architecture.
TFT LCD panel factory has invested in the manufacture of embedded bridge on cell panel module, which can be produced in one stop from indium tin oxide (ITO) glass, cover glass to touch panel module, fully mastering the yield, capacity and production efficiency of the production line, while reducing the manufacturing cost, Even in the future, the price is expected to be more competitive than OGS panel modules, which attracts many panel manufacturers to compete for layout.
with TFT LCD panel suppliers competing to join the bridge on cell touch market.
the market living space of OGS touch panel industry will also be seriously compressed.
Wang Jiayu pointed out.
at present, OGS is the mainstream of the touch screen market of medium and high-level smart phones, In order to avoid falling into the mire of price competition and gain industrial dominance, panel factories are speeding up mass production of bridge on cell touch solutions by the end of the year, and the terminal products will be available as soon as 2015, The bridge on cell touch solution will start to carve up the market of OGS in the medium and high-level smart phones.
the market of OGS in the medium and high-level smart phones will be dividedIn view of this,.
OGS and Chinese mainland OGS panel factories are working hard to prevent the TFT LCD panel from being powerful by the product strategy of high integration. If Ou Feiguang is to integrate OGS module with camera module, it will try to win the middle and high class mobile phone customers. As for the touch chip business,.
has a high threshold for BridgeOn-cell technology. The main business is dominated by Synaptics, Italian semiconductor, Art Mel and Atmel. However, the Chinese mainland touch chip manufacturers including Suzhou Hanrui microelectronics have been catching up with the future. Whether the future will crush the troops and squeeze the penetration rate of foreign touch chip manufacturers. The proportion of white card and medium and low-level smart phones equipped with on cell touch solutions will continue to rise, Especially mobile phone mobile phone with mobile On-cell is more popular..
white mobile phone factory supports single layer multi point On-cell flaming with the cost of single layer multi touch On-cell touch up..
Chinese mainland white card and low and middle order mobile brand factory plan to expand import in the new generation product line in 2014, thus developing a smart and cheap smartphone. Accelerating the penetration of the market is expected to boost the demand for single-layer multi-point on-cell touch solutions.
said Jimmy Lin, senior product marketing manager of Xinsi international.
compared with the bridge on cell touch solutions, which are rapidly emerging in the middle and high-level smartphone market, the single-layer multi-point on-cell touch solutions only need a single-layer mask, so the production cost can be lower, .
mobile phone mobile phone is more suitable for the low and middle level Smartphone Application. According to the understanding of.
2013 single layer multi touch On-cell touch scheme, many Chinese mainland white and medium low level mobile phones are adopted.Even Google and Motorola introduced single-layer multi-point on cell touch solutions to their smart phones nexus 5 and moto g respectively in 2013 with the help of touch chip technology of Xinsi international.
NPD DisplaySearch analysis, a market research organization.
after the failure of production, panel manufacturers have gradually realized that, When developing on cell touch solutions, LCD noise processing and gesture judgment algorithms are not their expertise, so they have stepped up cooperation with touch chip manufacturers to break through the technical shackles, improve yield and reduce costs.
therefore, after preliminary preparation, panel manufacturers have planned to expand the mass production of single-layer multi-point on cell touch solutions in 2014, For example, Tianma microelectronics's 4.5-inch fwvga and 5-inch 720HD products, BOE's 4.5-inch QHD and 5-inch 720HD products all adopt the single-layer multi-point on cell touch scheme design.
the single-layer multi-point on cell touch scheme was proposed by the touch chip supplier in 2012.
compared with the bridge on cell touch scheme, the electrode pitch cannot be very fine, Lin pointed out that in the architecture of single-layer multi-point on cell touch scheme, indium tin oxide (ITO) conductive film and optical film are all single-layer, which can reduce the overall bill of materials (BOM) cost, However, it needs exclusive patterns and firmware.
in general.
the single-layer multi-point on cell touch scheme relies on the price advantage,It has gained the favor of Chinese mainland white label and low and middle tier mobile phone brands. And more and more panel factories are stepping up their product layout and production, which is expected to accelerate market penetration. In the future, it will gradually erode the market share of GFF touch scheme in the middle and low-level smart phones.
although OGS and GFF are still in the middle of the mainstream touch panel technology of high-level and middle and low-level smart phones at the present stage (Figure 3).
however, under the strength of panel manufacturers, the penetration rate of bridge on cell and single-layer multi-point on cell touch scheme in the smart phone market will rise rapidly, In the future, the trend of competing for the mainstream market is expected to rise.

after panel manufacturers speed up the production of on cell touch solutions, it will gradually impact the market share of existing touch panel manufacturers,
