The three types of touch screen technologies for LCD advertising machines refer to nano touch screens, infrared touch screens, and capacitive touch screens. LCD advertising machine manufacturers explain from the perspective of industry development that infrared technology is more mature than nano technology, with a response time of a few microseconds. However, the lifespan of nano technology is longer than infrared technology, and the products made with nano technology are waterproof, ash proof, explosion-proof, and more lightweight compared to coffee tables. The touch sensitivity of capacitors is higher than that of nanometers and is not affected by light environment. Moreover, the products made from capacitors have higher sensitivity, stronger explosion-proof performance, and more stable performance than nanometers coffee tables.
Features of Nano Touch Screen for High Brightness Display Screen Advertising Machine:
This product has a very high cost performance ratio because the nano touch film is a transparent film that can accurately sense the touch of the human hand or across the base. It is the core component of precise positioning devices such as touch screens, which is a crucial solution to achieve precise touch positioning. It consists of four parts: PET film, nanowires, control circuit board, and driver software, with the lowest cost among the three.
Features of the infrared touch screen of the high brightness display advertising machine:
Infrared touch screen utilizes a dense infrared matrix in the X and Y directions to detect and locate user touch. The infrared touch screen is equipped with a circuit board outer frame in front of the indicator, and the circuit board is arranged with infrared emission tubes and infrared reception tubes on all sides of the screen, corresponding to a horizontally and vertically crossed infrared matrix. When users touch the screen, their fingers will block the horizontal and vertical infrared rays at that position, so that they can determine the position of the touch point on the screen. The external touch screen is a highly integrated electronic road integration product. The infrared touch screen includes a complete integrated control circuit, a set of high-precision, anti-interference infrared emitting tubes, and a set of infrared receiving tubes, which are cross installed in two opposite directions on a highly integrated circuit board, forming an invisible infrared grating. The intelligent control system embedded in the control circuit continuously emits pulses to the diode, forming an infrared biased beam grid. When touching objects such as fingers entering the grating, the light beam is blocked. The intelligent control system will detect the loss of light and transmit flag and light signals to the control system to confirm the X-axis and Y-axis coordinate values.
Characteristics of High brightness Display Screen Advertising Machine Capacitor Touch Screen
The touch screen is a transparent relative positioning system, and first of all, it must be transparent. Transparency is achieved through the use of advanced material technology. Secondly, it can provide the relative coordinates of the touch points of the fingers, while the mouse belongs to a relative positioning system. The characteristic of a relative coordinate system is that the coordinates of each positioning are not related to the coordinates of the previous positioning. The touch screen is physically an independent coordinate positioning system, and the position of each touch is converted to the coordinates on the screen.
