Analysis Of Three Touch Screen Technologies Of LCD Advertising Machine
Aug 28, 2018
LCD touch screen technology refers to nano touch screen, infrared touch screen, capacitive touch screen. When the user first knows the price, the LCD advertising machine chooses different touch screens to have different price differences, which will bother users to purchase. The LCD player cannot be selected correctly. As for saying that is the best? Can only say that there is no best, only more appropriate, one point price and one quality. LCD advertising machine manufacturers can talk about the development of infrared technology than the nano technology, the response time is a few microseconds, but the life of nanometer is longer than that of infrared, and the nano-made products are waterproof compared to the coffee table. Anti-grey and explosion-proof! And it's lighter. The touch sensitivity of the capacitor is higher than that of the nanometer, and is not affected by the light environment, and the product of the capacitor is higher in sensitivity than the nano-coffee table, the explosion-proof property is stronger, and the performance is more stable.
LCD advertising machine nano touch screen features:
This model is the most cost-effective, because the nano-touch film is a transparent film, which can accurately sense the touch of the human hand through the base. It is the core component of the precise positioning device such as the touch screen, and it is the solution to the precise touch positioning achievement. It consists of four parts, PET film, nanowire, control board and driver software, and the cost is the lowest among the three.
LCD advertising machine infrared touch screen features:
The infrared touch screen uses an infrared matrix densely packed in the X and Y directions to detect and locate the user's touch. The infrared touch screen is provided with a circuit board outer frame on the front side of the display device, and the circuit board arranges the infrared emitting tube and the infrared receiving tube on the four sides of the screen, one by one corresponding to the infrared matrix which is horizontally and vertically crossed. When the user touches the screen, the finger will block the two infrared rays in the horizontal and vertical positions at the position, so that the position of the touch point on the screen can be determined or determined. The external touch screen is a highly integrated electronic road integration product. The infrared touch screen includes a complete integrated control circuit, and a set of high-precision, anti-jamming infrared emission tubes and a set of infrared receiver tubes. The crossover devices form an invisible infrared light in two opposite directions on a highly integrated circuit board. Grating. An intelligent control system embedded in the control circuit continuously pulses the diode to form an infrared polarization beam grid. When a touch object, such as a finger, enters the grating, the beam is blocked. The intelligent control system detects the loss of light and transmits the flag light to the control system to confirm the X-axis and Y-axis coordinates.
