The development trend of the application of touch screen technology

<p>The maturation of <a href="https://www.toponetechdisplay.com/industrial-monitor" target="_blank">touch screens</a> presents a trend of specialty, multimedia, stereo and big screen. Together with the development of the information society, individuals need to acquire a number of general information. The general public information transmission system that uses touch screen technology as an interactive window employs advanced computer technology and utilizes text, pictures, music, comment, cartoon, video and other forms to and vividly introduce various info to people and bring them to people. Comes great advantage.</p><p><br></p><p>Projected capacitors support , while surface-type capacitors only encourage single-point touch; projected capacitors make it possible for gloves to be entered and can be controlled through a coating of cover glass, neither of which can be achieved with surface-mounted capacitors.</p><p><br></p><p>The dimensions of the touch panel is critical</p><p>From the touch panel market, the bigger the size, the more often the cost will not increase proportionally, but depends on the execution of this technical basis and related component costs, but the size remains a significant step to go over this technology. Especially for different application environments and practical goods, their panel requirements are somewhat different, and the precision requirements for their touch technology will also be different.</p><p><br></p><p><img src="https://img80003129.weyesimg.com/uploads/p5ok8zti.allweyes.com/images/15686820962751.jpg?imageView2/2/w/931/q/90/format/webp"></p><p><br></p><p><strong>●Little size touch panel (4 inches or less)</strong></p><p>The generally small size, generally identifies products under 4 inches, most commonly utilized in consumer electronics products like digital cameras, cellular telephones, personal digital assistants, PND... The program products within this marketplace are extremely broad, and also the technical maturity of products and components is high, Relative to the product's gross profit performance is the most subtle.</p><p><strong>●Medium and small size signature panels (5-9 inches)</strong></p><p>The signature panel dimensions of 5-9 inches are largely utilized. Presently, advanced products are the most widely utilized, for example as higher-end PNDs, digital photo frames, ATMs, or outside KIOSK. . .etc., capacitive panels are for the most part used for demand Outdoor KIOSK apparatus with higher durability requirements are mainly utilized, whilst customer PNDs and electronic photo frames are still controlled by low-cost resistive touch panel software.</p><p><strong>●Medium and large size touch panels (10-21 inches)</strong></p><p>Refers to the 10 to 21 inch size panel. This part is largely used in industrial computers and commercial touch screens. The main technologies is capacitive touch, even though there are different touch layout products such as acoustic wave induction and resistive touch.</p><p><strong>●Enormous size touch panel (22 inches or longer )</strong></p><p>It is a touch product of 22 inches or even more, and the debut of large-size touch screen technology is significantly more diverse, because the performance of resistive and capacitive types on large-size screens has its own physical constraints, although large-scale technologies have been implemented in series. , However, the technologies used within this market is relatively varied. It's more commonly used overseas for self-service systems, such as processing lottery (Lottery), bingo (Bingo) only device, or gambling machine (Gaming Machine)... and other software.</p><p>With the growth in size of the signature panel, the machine must be incorporated with the built machine. In the event the inherent constraints of this signature technology (such as larger size and heavier weight) affect the integrated product, it is not a system operator. The results that I am happy to see, consequently, the sonic and infrared touch control technology which might raise the volume of the item, the marketplace functional program is limited, but the resistive and capacitive touch are far more readily favored by associated businesses.</p><p><br></p><p>Capacitive touch is catching up</p><p>Currently, the apparatus integrating touch technology are rather varied, mainly including cellular phones, PNDs, game consoles, PMP... along with other multimedia or communication peripherals. At this stage, the program remains dominated by small dimensions, and large touch panels are relatively popular in market applications. . Particularly for iPhone smart phones, the attractive control experience is the trick to the touch technology merchandise impulse, as well as the large-size products in Windows 7 and also Microsoft's previously declared Surface computer technology may also stimulate the gain in the market for moderate and large-size touch software. temperature. Because the growth of resistive touch technology is much more mature, however, the benefit of relative products can also be lower, and its own multi-finger signature technology execution has its own Limitations, although some manufacturers have developed resistive touch technology comparable to capacitive multi-touch for the requirements of multi-finger signature, the implementation complexity of this technology is comparatively high, and also the program market also requires some time to test.</p><p><br></p><p><a href="https://www.toponetechdisplay.com/introduction-to-the-capacitive-touch-screen-option" rel="noopener noreferrer" target="_blank"><strong>Capacitive touch technologies</strong></a>, resulting from the massive use of the iPhone, has generated global attention and madness. The iPhone is the best promotional sample of capacitive touch technologies. Its multi-finger signature and smooth functioning experience have brought many touch tech producers. They have invested in budgets to create similar multi-finger touch engineering and key components.</p><p>Diversified touch technologies</p><p>The principle of resistive touch is the upper/lower two sets of ITO conductive films are superimposed, and the pressure causes the electrodes to appear conductive, and the voltage change is detected by the controller to figure the contact place to complete the whole contact detection procedure. The trick to use The material is a conductive film, and the transparency of the movie will impact the display effect, but the benefit is that the technology is mature, there is no patent burden, and the cost is obviously significantly reduced.</p><p><br></p><p>Looking at the current touch technology marketplace, though resistive touch technology is the most frequently utilized, the remainder is your popular capacitive touch technologies, and now there are multiple technology practice models such as infrared and infrared... But infrared and infrared technology are equally compared. Suitable for large-screen programs, such as electronic billboards or electronic whiteboards... and other touch methods. Formerly, I also mentioned Surface technology a little bit. This is a large rear projection screen to earn a multi-finger touch effect very similar to this iPhone. Its signature area is often as big as a desktop computer, and the maturation of touch software is more interesting. So long as the latest, fastest, biggest... and other merchandise performances, they can achieve certain marketplace recognition and market share. However, touch technology is rather different. If the technology can't meet user customs, it will also have an effect on the success or failure of the technology.</p><p><br></p><p><img src="https://img80003129.weyesimg.com/uploads/p5ok8zti.allweyes.com/images/15713924156014.jpg?imageView2/2/w/1000/q/90/format/webp"></p><p><br></p><p>For example, the iPhone touch technologies, which is famous for multi-finger signature, may possess its application value for cellular phones, but if it's applied to products with a moderate screen size in laptop computers, the operational requirements of multi-finger touch goods may become comparatively low, even The cost of components in reaction to multi-fingerprinting may also alter the acceptance of products into the industry.</p><p><br></p><p>In order to snatch the touch market cake, for the touch panel, the resistive touch technologies which still accounts for the majority of the current market, even if it has a home advantage, it doesn't dare to ignore it. Nonetheless, in order to continue to keep market benefits, related companies have also developed non-PE movies. The resistive touch module in glass (glass) greatly enhances the original technical limitations due to little material improvements in light transmittance, durability and accuracy.</p><p><br></p><p>Additionally, in the layout demands of multi-touch, some companies have introduced a resistive touch structure, but at exactly the same time can achieve multi-finger signature, identification of new technologies, has overturned"multi-finger touch" ="capacitive touch Technological advantages. By comparison, capacitive touch technology, because of the technical principles of electric field evaluation and detection of current touch coordinates, has resulted in the touch panel in order to effectively increase in manufacturing size, which comparatively limits its market advertising. At the moment, the mainstream size of capacitive touch panels remains confined to 15 inches or less. But under the repeated technical improvements of the industry, the current cost size has reached about 32 inches. The related technologies have already achieved mass manufacturing strength. The following step is the way to efficiently reduce manufacturing costs.</p><p><br></p><p>How to solve the patent spell, the key to capacitive touch Marketplace</p><p>In present, most of the patents associated with capacitive touch technology have been mastered by several major manufacturers, notably the quality of key touch ICs, which impacts the performance of the true touch encounter. When the user rolls using a finger, then the capacitance value changes. At this time, the touch IC converts the precise touch coordinates, and the whole procedure panel It may get noise in the exact same time, and its own motion sensing operation method is complex. One of them, you will find a bunch of patented technical limitations that prevent other manufacturers from easily entering the marketplace. Manufacturers may also hinder the acquisition expense of signature ICs, which will boost product costs.</p><p><br></p><p>It's generally believed that capacitive touch technology is more difficult to divide the size limitation, and also the size of this evolution might be smaller than that of resistive touch. In fact, capacitive touch isn't impossible in larger-size panels, also its cost structure cannot Compete together with the resistive touch panel technologies of the exact same dimension has led to a lack of interest in mass production by applicable manufacturers.</p><p><br></p>
