The principle of touch display is actually very simple. Simply put, just install a touch screen on the display and become a display with touch function. Currently popular on the market is the liquid crystal touch display. According to the difference of the installation of the touch screen, it is generally divided into four types: resistive, capacitive, sonic, and infrared; currently, the touch display on the market mainly uses a resistive touch screen, because it is relatively simple to install. Beijing Chuangke Hengyuan Technology Development Co., Ltd. based on the needs of market customers, spontaneously opened a model to design an all-in-one touch display, which is not like the other type of display on the market, the modified touch display is easy Quality problems occur, and touch-screen displays that are developed in an integrated design are less prone to touch screen damage.
From the front, the touch display is not significantly different from the ordinary display. From the back, there is one more signal line than the ordinary display, that is, the signal line connecting the touch screen. When a normal display is in use, a special driver is generally not required, and the touch display must have a dedicated touch screen driver when it is used, otherwise the touch operation cannot be performed. Basically, internationally renowned brands include 3M, ELO, GVision, etc. Domestically, there are manufacturers such as Hengyuan, ONETOUCH, ETWO, etc. The domestic market is relatively chaotic, and basically no big brands are formed. Most of them are removed by a general liquid crystal display, and then the touch screen is attached. The Chuangke Hengyuan touch display is made by one-piece mold opening, and its outlet is relatively large.
First of all, as a professional touch display manufacturer, the overall mold and mechanism design, the layout of electronic accessories, and the fixing of the touch screen are all unique methods. In addition to the GVision products, in addition to the self-developed A/D board, the whole The design of the mechanism has also been professionally designed for the fixing of the touch screen. Several unique iron pieces are used as the fixing, instead of simply fixing and pasting with the rubber strip. Secondly, the professional touch display is generally reserved. A certain degree of installation space, can be compatible with the installation of other touch screens. Third, the professional touch display work is relatively stable, not only the contact is accurate, in addition to the touch contact, the display machine will not shake, relatively stable. Fourth, the touch display The quality of the machine is guaranteed. Therefore, the comprehensive performance is more reliable. This type of touch display is generally used in relatively high-end and strict touch display requirements, such as high-end catering POS systems, industrial sites, medical systems, conference rooms, etc.
