Touch screen, also known as "touch screen", "touch panel", is an inductive LCD device that can receive input signals such as touches. As one of the latest computer input devices, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction.   The first characteristic of a touch screen. Transparent, it directly affects the visual effect of the touch screen. Transparent degree of transparency, infrared technology touch screen and table + - surface acoustic wave touch screen is only separated by a layer of pure glass, transparent can be considered the best, other touch screen this point should be well pushed some, "transparent", in the touch screen industry, only a very general concept, many touch screen is a multi-layer composite film The second characteristic of the touch screen. Touch screen is an absolute coordinate system, to choose where to directly point that, and the mouse this type of relative positioning system is the essential difference between the intuitive once in place. The third characteristic of touchscreens. Detection of touch and positioning, a variety of touch screen technology is dependent on their own sensors to work, and even some touch screen itself is a set of sensors. The respective positioning principles and the respective sensors used to determine the speed of response, reliability, stability and life of the touch screen.

  The cover plate is a transparent lens attached to the outside of the electronic display screen and used to protect the touch display module of the touch display screen and the screen of the non-touch display screen. The touch module of the touch screen is a precision-processed sensitive component. If it is exposed to the outside, it will easily affect its use effect and life due to abrasion and scratches from sharp objects. water ripples, etc. Therefore, a cover plate needs to be added outside the display screen to protect the touch module and the display screen from damage. According to the material analysis of the cover plate substrate, the cover plate can be mainly divided into glass cover plate, ceramic cover plate, plastic cover plate and optical composite material cover plate: (1) Glass cover: Glass is a transparent semi-solid material with good light transmittance and special texture. After ion exchange, it can enhance the surface hardness and toughness. It is currently a widely used material in China's cover plate industry. (2) Ceramic cover: The light transmittance of the ceramic cover is poor, and it is mostly used in the rear cover. At the same time, the processing cycle of the ceramic cover plate is long, the process is difficult and the cost of input is high: (3) Plastic cover: Usually, acrylic material, namely polymethyl methacrylate (PMMA), is an early developed thermoplastic with good transparency and chemical stability, and acrylic material is cheap and easy to machine, but it is resistant to heat and acid and alkali resistance are poor. (4) Optical composite material cover: Optical composite materials are cover materials with optical functions based on multi-layer resin materials (PMMA.PC) as the base material. Compared with plastic materials, they have higher light transmittance and overcome the fragile nature of glass and ceramic materials. The shortcomings have become an important development direction of China's cover plate industry.

  Advantages: 1. Novel operation The capacitive touch screen supports multi-touch, making the operation more intuitive and interesting. 2. Not easy to touch by mistake Since the capacitive touch screen needs to sense the current of the human body, only the human body can operate it, and it will not respond when touched with other objects, so the possibility of accidental touch is basically avoided. 3. High durability Compared with resistive touch screen, capacitive touch screen has better performance in dustproof, waterproof and wear-resistant.   Disadvantages: 1. The accuracy is not high For technical reasons, capacitive touchscreens are less accurate than resistive touchscreens. Moreover, only fingers can be used for input, and it is difficult to recognize complex handwriting input on a small screen. 2. Susceptible to environmental impact When environmental factors such as temperature and humidity change, it will also cause instability or even false touch of the capacitive touch screen. For example, when a user moves his body close to the screen while using it, it may cause drifting, and even operating in a crowded crowd may cause false touches. 3. High cost In addition, the current capacitive touch screen still has certain technical difficulties in the step of attaching the touch panel to the LCD panel, and the yield is not high, so the cost of the capacitive touch screen is also increased invisibly.

Optical Bonding has the following advantages compared with the traditional frame sticking (mouth glue sticking) method:   1. Better display effect. Optical Bonding technology eliminates the air between the screens, which can greatly reduce light reflection and reduce the loss of transmitted light, thereby increasing the brightness and enhancing the display effect of the screen. 2. The screen is isolated from dust and water vapor. The air layer of the ordinary bonding method is easily polluted by dust and water vapor in the environment, which affects the use of the machine; while the OCA glue of Optical Bonding fills the gap, the display panel is closely attached to the touch screen, and dust and water vapor have nowhere to enter, maintaining the screen of cleanliness.     3. Reduce noise interference. In addition to improving the strength of the touch screen and the display panel, Optical Bonding can effectively reduce the interference caused by noise to the touch signal, and improve the smoothness of the touch operation. 4. Make the body thinner. The Optical Bonding screen has a thinner body, and the touch screen and the display are bonded with optical glue, which only increases the thickness of 25-50μm; it is 0.1-0.7mm thinner than the ordinary bonding method. The thinner module thickness provides greater flexibility for the structural design of the whole machine, and the thinner body improves the product quality and highlights the technical content.     5. Simplify assembly. The assembly of the Optical Bonding module and the whole machine can be directly fixed by means of snaps or locking screws, which reduces the assembly problems caused by the bonding deviation, and simplifies the assembly process and reduces the assembly cost. The Optical Bonding module does not need to consider the protection of dust and water vapor, and can achieve a narrower frame. At the same time, because it does not need to consider the double-sided bonding strength, it also contributes to the design of a narrow.

  How resistive touch screen works       The part of the screen body is made of a composite film that matches the surface of the display, the base layer is plexiglass or a layer of glass, the outer part has a conductive layer, and there is a hardened rough surface layer on top. When the user's hand touches the screen, there will be a contact at the touch point, which are two conductive layers that are usually insulated from each other. One of the conductive layers is connected to the voltage scene in the y-axis direction. At this time, the voltage of the detection layer changes from zero to non-zero. During this switch-on process, the controller has detected and then switched between them. This can also be said to be the same basic principle of all resistive touch screens.​​​​   How capacitive touch screen works       Usually, there is a sense of electric current in the human body, and it is only by using this point that we can work. It is composed of two double-layer composite glass screens, which are coated with a layer of ITO in the glass layer and in the middle of its interlayer. The outer layer is a protective layer of glass, and the ITO layer in the middle of the interlayer is used as a working surface. When the user's finger touches the metal layer, in the presence of the electric field of the human body, the user and the surface of the touch screen will combine into a capacitor, which is a direct conductor. The capacitive controller can accurately calculate where the touch point is through the ratio of the current.​​   How infrared touch screen works     The principle of the infrared touch screen is to use the infrared matrix in two different directions of y and x to accurately locate and monitor the touch position of the user. The outer frame of the circuit board is installed at the front end of the display, and then the circuit board cannot separate the infrared receiving tank and the transmitting tube around the screen. When the finger touches the screen, the two infrared rays intersecting at the position of the core will be directly blocked by the finger, so any position of the touch point on the screen can be accurately determined.  

  Advantage: 1. There are no physical buttons, and software can also be used to achieve various operations, such as zooming in, moving, etc. 2. Multi-touch (more than two points) can realize various inputs such as zoom in and zoom out. 3. The displayed operation object is consistent with the input object, and has intuitive operability. 4. The integration of input and display can realize the miniaturization of the machine, and the degree of freedom of design is relatively high. 5. There will be no gaps like keyboards, switches, etc., entering garbage, dust, water, etc., not easy to damage, and easy to maintain.   Shortcoming: 1. Not suitable for keyboard, mouse, buttons and other fast input. 2. Direct touch display, the screen is easy to be polluted, and it is difficult to read the information; it is easy to cause misoperation due to scratches and so on. 3. There is no click like a button or a mouse, so the input action will become awkward (there is also a touch screen that can get a click). 4. It is difficult for the blind to use it, so it needs to be used together with voice instructions and buttons, or to specify the touch position.
