>> 1T2R touch panel introduced LCD on-cell is expected to grow 7th,Apr,2017
2015 display panel manufacturers such as the Japanese display, Samsung display, LG display, Tianma, BOE, AU Optronics, Qunchuang photoelectric and other significant increase in the supply of embedded touch panel, such as LCD in-cell, LCD on-cell As well as the AMOLED on-cell type, which has a huge impact on the additional touch panel market.
The penetration rate of the embedded touch panel in 2015 is 40% for Huawei's technology, 40% for Huawei, 17% for LG, 17% for ZTE, 34 for Oppo Mobile for 34 %, Vivo communication technology is 26%
2016 year in addition to Apple and Samsung Electronics after all other brands of embedded touch panel use will increase the proportion of 15-20%.
In 2016 Samsung Electronics and Apple are likely to increase the popularity of AMOLED on-cell and LCD in-cell panels, respectively, which will add add-on types such as GFF, GFM, OGM Touch panel market has become more difficult.
As of 2015, in a variety of embedded panel types, AMOLED on-cell has been Samsung Electronics, Oppo, vivo, Huawei, Jin Li communications, ZTE, Meizu technology, HTC used, at the same time, LCD in-cell Has been used by Apple, and as of 2015, Huawei, LG Electronics, millet, ZTE, Cool Digital, Motorola Mobile, Lenovo and Microsoft have adopted the LCD on-cell.
For LCD on-cell, until the end of 2015, the mainstream is a single-layer sensor with a five-point touch panel, the panel sensor (Tx) and receiver (Rx) on the same side. Is a single-layer model that becomes Caterpillar in the industry, which is more competitive in price than the touch models separated from the sensing layer (Tx) and the receiving layer (Rx), as compared to the two-layer model A single layer requires less than two or three photomasks. However, the number of pins connected to the flexible circuit board (FPC) is increased to 300 to 400 based on the 5-inch module, which results in a decrease in FPC bond yield.
In order to solve these shortcomings, a known as the "1T2R type" of the Caterpillar model was developed. In order to distinguish between old and new versions, the old model is called "1T1R model", and the new model is called "1T2R model".
As shown in the figure above, Tx and Rx have 14 and 26 transmission channels, respectively, with a two-layer projection capacitive touch panel with 40 pin count, and "1T1R model" and "1T2R model" with 378 pin and 210 Contacts. Although the number of stitches of 1T2R is 170 knots compared to the two-layer model, the number of stitches of 168 is less than that of the 1T1R model.
The reduction in the number of channels results in a reduction in the number of needles and a reduction in the size of the FPC, which makes the bonding process much easier. In particular, with the rise in bond yields, price competitiveness has also improved. In addition, the LCD module (LCM) company through the LCD panel manufacturers to buy 1T2R models of LCD semi-finished products, you can not need to invest any additional equipment on the equipment to produce 1T2R model module.
In the LCD panel manufacturers, the group of optical, HannStar Display, BOE is now mass production 1T2R model LCD on-cell, at the same time, CPT, Pegasus Microelectronics is also preparing to produce the model products. HD (HD) or full-width image graphics array resolution silicon thin film transistor (TFT) -LCD panel gradually lost market competitiveness. Recently, the newly developed 1T2R model is being applied to the TFT-LCD panel, which led to TFT-LCD panel market competitiveness has been improved.
Innovative smartphone brands such as Motorola, Microsoft, Cool Digital, Konka, Jin Li, Huawei and ZTE are actively applying the 1T2R model on-cell touch LCD to some low-end smartphone models below $ 100. China's smart phone design and manufacture of self-brand 1T2R models have a great concern.
If the 1T2R model LCD on-cell can achieve the expected price competitiveness, then it will erode the low-end smart phone GFM touch panel market.
