Infrared touch screen development
For a long time, the touch screen market has been in a colorful situation. Touch screens with different technologies adapt to different application environments. Infrared touch technology is just one of them, with its own advantages and disadvantages. People in the industry are extremely fond of the advantages of infrared touch technology, are also very aware of its shortcomings, and have made unremitting efforts to improve. So far, infrared touch technology has entered the fifth generation. Judging from some of its characteristics, it is very likely to stand out from various touch technologies and become the trendy player in the touch screen market.
The early infrared touch screen appeared in 1992, with a resolution of only 3232. The first generation of infrared touch technology has low resolution, is susceptible to environmental interference and malfunctions, and it is required to be used in a certain shaded environment. Due to these limitations, the infrared touch screen once faded out of the market.
The second-generation infrared touch screen was launched in 1994, with a resolution of 6464, improved anti-light interference performance, and can adapt to most indoor environments. The third-generation infrared touch screen was launched in 1997 with a resolution of 320240, which can be used in outdoor environments that are not exposed to direct sunlight; the main contribution of the fourth-generation infrared touch screen is to increase the resolution, reaching 800600, in 1998 roll out. From the perspective of the development history of infrared touch screens, the main progress is to improve the resolution and adapt to the environment of strong light interference, but basically did not overcome the short product life and easy drift of device characteristic parameters.
La technologie tactile infrarouge de cinquième-génération récemment lancée augmente non seulement la résolution à 1000720, mais améliore également les performances d'interférence anti-éblouissantes à utiliser dans les environnements à lumière directe du soleil. Plus important encore, il possède des fonctionnalités essentielles en termes de durée de vie du produit et-de performances sans maintenance. saut. La touche infrarouge de cinquième-génération adopte l'idéologie directrice de la distribution redondante des appareils à fonction de probabilité, et la durée de vie est supérieure à 7 ans dans un environnement de travail. C'est-à-dire que lorsque l'écran de support atteint la fin de sa durée de vie, l'écran tactile lui-même fonctionne toujours normalement.
The improvement in the performance indicators of the fifth generation infrared touch screen is enough to push the application of touch screen to a new level. What could not be used in some occasions can now be used. For example, in the past, the touch screen had many broken pens when tracking the movement of the finger, which could not be used for Chinese character recognition. The accuracy, smoothness and tracking speed of the fifth-generation touch screen can meet the requirements when tracking the trajectory of the finger. The user's writing can be converted into an image trajectory very smoothly, fully supporting handwriting recognition input.
The sixth-generation touch screen has supported multi-touch in order to meet the requirements of the windows7 system.
Infrared touch screen trend
In fact, a single device like the fifth-generation touch screen can already be used as a complete human-machine interface platform, replacing the mouse, writing pad and even the keyboard.
From the application level, the touch screen should not only be a simple device that converts the touch position into coordinate information, but should be designed as a complete human-machine interface system. The fifth-generation infrared touch screen is based on such a standard, and realizes the improvement of the product concept through the built-in processor and perfect driver software.
Therefore, the new infrared touch technology will have a very significant impact on the domestic and foreign markets.
First, the fifth-generation infrared touch screen is very likely to stand out, breaking the world pattern of acoustic wave screen, resistive screen, capacitive screen, and infrared screen. The most likely situation is that infrared screens occupy more than 80 percent of the mainstream market, resistive screens and capacitive screens are locked in applications below 4 inches, and acoustic wave screens will be gradually eliminated.
Second, the fifth-generation infrared touch screen is expected to break the long-term occupation of the domestic market by foreign manufacturers, and remove American and Japanese touch screen products from the Chinese market with better quality and lower prices. However, some manufacturers in Taiwan Province of my country will occupy an important position in the mobile product market with five-wire resistive touch screens.
Third, by making full use of product advantages and increasing international market operations, the fifth-generation infrared touch screen can compete with foreign products in the international market. However, it should be noted that the product advantages of the fifth-generation infrared touch screen can be maintained for a limited time. The research and development efforts of foreign manufacturers cannot be ignored, and the technical advantages of a single product may soon disappear.
Quatrièmement, grâce à l'amélioration des fonctions et des performances, la cinquième génération d'écrans tactiles infrarouges ouvrira de nouveaux domaines d'application. Par exemple, les écrans tactiles infrarouges peuvent fréquemment apparaître dans des industries telles que le contrôle industriel et les appareils ménagers, et constituent un substitut aux périphériques d'entrée tels que les souris et les tableaux d'écriture manuscrite. La relation avec la concurrence a un impact sur le marché des produits connexes.
Frequently Asked Questions about Infrared Touch Screen
How to solve the problem that double-click is not very sensitive?
·Open the mouse item of the control panel and lower the sensitivity.
Under what circumstances need to calibrate the touch screen?
·No need to calibrate, automatic detection.
Why is there no right-click function?
·Open the touch screen control panel, tick the right-click function option, and hold on the touch screen for about 2 seconds.
Why does the touch screen drift when clicking?
·The finger must be straight in the touch area, and no more than one touch body enters the touch area.
