The future development of touch display
recently, the "2016 China high tech Industry Conference" jointly hosted by OFweek China high tech industry portal and smart life was held in Shenzhen. At the sub forum of "OFweek China new display technology and application seminar" held at the same time, Gong Zhenbang, director of Duntai technology marketing department, delivered a keynote speech on "the future development of touch display", which analyzed in detail the development process and future trend of touch display
we all know that if the iPhone in 2007 is regarded as the starting point for the combination of intelligence and touch panel, it will be 10 years before 2017, during which the touch industry has experienced many technological changes. The research and development of embedded panels has been carried out since 2007. Finally, although it converges on the projection capacitor technology, there is a bifurcation point that in-c meets the test specifications of ell and on cell. On cell has nothing to do with panel drive technology and TFT process, so it develops rapidly. In the past 10 years, on cell mainly started from the line structure of sito, and then introduced the low-cost scheme of single-layer and multi-point; AMOLED and LCD can be imported. As for in-cell, the more meaningful starting point should be iphone5 in 2012, and time sharing and the patterning of VCOM layer are used as touch electrodes. These two basic features affect almost all subsequent in-cell structures
for the development of display, Gong Zhenbang pointed out: "In 2009, the display adopts the structure of display module and flat cover glass, which is basically a hard screen. In 2013, the flexible display appeared, and in 2017, with the application of AMOLED, the flexible display will appear. The evolution trend of the display is to achieve flexibility, and the evolution result is process integration. In the future, with the growth of vr/ar applications, it will bring new business opportunities to AMOLED panels, in which the grating sensor is easy to realize digitization and high precision (at present, the highest resolution can reach the nanometer level), strong anti-interference ability, no artificial reading error, convenient installation, reliable use and other advantages. " Then, Gong Zhenbang introduced in detail the new requirements of vr/ar for displays, and reviewed the development of vr/ar products in 2016
finally, in view of the future development of touch display, Gong Zhenbang concluded: "3D touch can become one of the differentiation methods of in cell LCD; AMOLED will quickly penetrate the market in the next 3-5 years due to a large amount of capital investment, and vr/ar will be an important indicator of AMOLED specification; flexible AMOLED will use add on TP film as the touch scheme in the initial stage of development."
under the internal economic cycle, China Chengdu Construction Expo in April 2021 will talk with you about opportunities in the process of new experiments in the industry or at the end of the test
in 2020, with the outbreak of the global epidemic and the prevention and control of the domestic epidemic effectively controlled, the global economic pattern has also undergone great changes, and China is moving forward under the strong strategic deployment of national policies [details]
