What Are The Types Of Touch Screens?

<p>The type of <a href="https://www.toponetechdisplay.com/" rel="noopener noreferrer" target="_blank"><strong><a href="https://www.toponetechdisplay.com/" target="_blank">touch screen</a></strong></a> is not limited to ordinary capacitive touch. According to its development process, many different touch types have emerged, and various touch interaction effects are also different, and even the touch method and touch medium are different. This is Because the motion principles of touch screens are different, and different touch screens are used on different devices, which types are included?</p><p><br></p><p><strong>What are the types of touch screens</strong></p><p><br></p><p><img src="https://img80003129.weyesimg.com/uploads/p5ok8zti.allweyes.com/images/15687037246598.jpg?imageView2/2/w/935/q/90/format/webp"></p><p><br></p><p><strong>1. The effect of pressing hard is good-resistive</strong></p><p><br></p><p>According to different principles, touch screens can be divided into resistive, capacitive, and wave (sonic, infrared) types, etc. The substrate of the <a href="https://www.toponetechdisplay.com/touchscreen-monitor" rel="noopener noreferrer" target="_blank"><strong>resistive touch screen</strong></a> is two-layer glass, and the inner side is covered with a conductive layer plated with indium tin oxide. The upper and lower layers are separated by insulating "spacers", and a thin scratch-resistant plate is added on the outside. The user presses on the touch screen to make the upper and lower layers contact and send out signals. Therefore, the upper layer is made of thin glass or plastic with a soft material and small depressions when touched, and the lower layer is thicker, harder glass. not fluent.</p><p><br></p><p><strong>2. The smoother and smoother you are-Capacitive</strong></p><p><br></p><p>In recent years, the touch product trend is the <a href="https://www.toponetechdisplay.com/pcap-touch-screen" rel="noopener noreferrer" target="_blank"><strong>capacitive touch screen</strong></a>, which is composed of multiple layers of materials. The outer layer is a high-hardness scratch-resistant material, and the middle layer is a conductive substrate. The surface capacitive screen is surrounded by four sides or four corners. As an electrode discharge, a uniform electric field is formed on the surface. Capacitance is to describe the "capacity of an object to store electrical charge". When the user touches the touch screen, since the human body conducts electricity, it affects the capacitance of the panel. At this time, the controller in the panel will calculate the position of the finger and the representative Features.</p><p><br></p><p><strong>3. Touch the big screen-wave type</strong></p><p><br></p><p>To make the touch screen bigger, it depends on the third operating principle: the wave touch screen. Generally speaking, it can be divided into surface acoustic wave and infrared. The principle is very similar. Surface acoustic wave screens are equipped with ultrasonic transmitters and receivers at the corners of the glass substrate, and reflective strips are installed on the four sides of the substrate; when a finger or soft material touches the panel, the ultrasonic waves will be blocked, causing signal attenuation. After the attenuation is compared, the position of the touch screen can be calculated.</p><p><br></p><p>Modern touch screens have greatly improved response speed and touch efficiency. After touch, they can respond quickly to improve work efficiency. Therefore, in many government affairs halls or banks and other service institutions, special attention is paid to the choice of touch screens. , It is even related to the user’s experience, and can even reflect the company’s comprehensive strength and service capabilities</p>
