The various touch screens have been sorted out in a cost-reducing way, and the advantages and disadvantages of various methods have been compared. Individual data varies due to the different test methods of each manufacturer. I will not go into details here, but each manufacturer is constantly trying to improve the various methods. The shortcomings of the display mode, the current touch screen technology has been greatly improved compared with the initial stage of development, so that people suspect that a new touch mode has appeared.
In the past touch screen market, the four-wire type has always led the market due to its own cost advantage. However, judging from the recent requirements for touch screens, for example, capacitive touch screens such as mobile phones cannot meet their performance requirements with the extension of the existing technology, so higher technologies are needed to support them. The following briefly summarizes the recent requirements for touch screens.
①Super high transmittance (>98 protsenti)
Lisaks ekraani pildikvaliteedi parandamisele on vedelkristallkuvari taustvalgustus muudetud CCFL-lt (külmkatoodiga luminofoorlamp) LED-i (valgusdiood), et vähendada energiatarbimist läbilaskvuse osas. Teatud panus on ka.
In addition, terminal displays such as e-books also require ultra-high transmittance. The use of optical functional films, low-reflection glass, and the optical connection of displays will be the direction for improvement in the future:
② Flattening
The mobile phone industry has already used printed decorations to cover part of the side circuit of the touch screen to achieve a flat integrated design of the touch screen and the outer frame, "Tmicli Wimlrnv" flat panel or "Touch Lens" (commonly known as flat touch screen or mirror touch screen) And other words are generalized. This trend is also ushered in medium and large touch screens. The 15hi flat-screen touch display using the "Acoustic Pulse Recognition (APR) Touch Technology" of the curved wave touch screen has been launched on the market.
③ hole space touch screen
The design perforated in a touch screen is unique. For example, with the development of car navigators and other designs toward full flatness, it is necessary to set the audio input and output terminal jacks in the effective touch area. As shown in Figure 3-15, surface capacitive and Inner capacitive touch screens can also be touched after drilling, as shown in Figure 3-16.
④ Flexible touch screen (to go to 〖TO)
The use of printing technology to manufacture electronic parts is attracting attention. Flexible TFT array substrates for electronic paper are under development. Under this trend, the touch screen is not only developing curved panels, but some people are also developing flexible touch screens.
