touch screen board classroom
Touch all-in-one PC hardware mainly divided into three parts, namely, LCD screen, touch screen and host computer. In these aspects, the LCD panel to determine whether the picture display resolution of the machine high-definition clear, not vague; Computer host decided to machine the overall performance of high and low, data processing speed and unhappy; Touch screen, as the main medium of users use machine operation, affect the user experience to the operation of the machine. Touch all-in-one PC is the advantage of operating it is very simple, convenient, do not need to use the traditional mouse and keyboard, touch screen board classroom users only need through the touch screen to complete the operation. So the touch screen selection is very important, is directly related to the stand or fall of user experience.
Touch screen in the market now is a lot of more phyletic, the main has a resistance capacitance screen, screen, infrared screen, acoustic screen, etc., the four kinds of touch screen is the mainstream of the touch-screen market application. Next, and the four kinds of touch screen to give you a simple introduction.
Resistive touch screens: excellent sensitivity and penetrability, 65 inch smart board longer service life and is not afraid of dirt, grease and jamming, suitable for all kinds of public places, especially need precision industry control. Mainly used in industrial control field, office, family and other fixed users of public places.
Sense of capacitive touch 65 inch touch screen screen: because the capacitance with temperature, humidity, ground conditions vary, so its stability is poor, prone to drift. Fear of the electromagnetic field can interfere with or drift, it is not easy to use in industrial control place and interference places. It doesn't need to have accurate public information can be used to query; Requires constant calibration, positioning.
Infrared sensor touch screen: low resolution, touch screen whiteboard but from the current, voltage, electrostatic interference, suitable for bad environment under the conditions of use; Suitable for all kinds of public places, offices, and asked not to high precision requirements of industrial control. And is suitable for large size touch screen equipment requirements, practical is the touch screen.
Acoustic screen touch screen: smart board touch screen pure glass material, excellent pervious to light, long life, good scratch resistant, suitable for unknown users of all kinds of public places. But afraid of dust dust and oil for a long time, so use in the place where the environment clean is better. In addition, need regular cleaning service.
In more than four touchscreen, suitable for application in touch query all-in-one product has two kinds of infrared screen and capacitive screen. Because the infrared touch screen technology is relatively mature and perfect, غير مجاز مي باشدt is low, so can be applied to any size of touch all-in-one PC products, while the capacitance screen can only apply to small products, big size product, the غير مجاز مي باشدt is too high, the price also is not غير مجاز مي باشدt-effective.
