- Touchscreen & HMI -

A touchscreen is one of Human-Machine Interface. It is an input device and normally layered on the top of an electronic visual display of an information processing system.

A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.

The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, keyboard, or other such.

人机界面是机器人和人类之间的接口界面,是基于计算机和人工智能技术。
触摸屏和液晶显示是最基本的人机界面。
当您触摸屏幕时,您向机器人传递了信息;当屏幕显示时,机器人向您表达了他的内心。

- Resistive Touchscreen -

A resistive touchscreen panel comprises two transparent electrically resistive layers facing each other with a thin gap between.

The bottom is the LCD screen.

One layer has conductive connections along its sides, the other along top and bottom. Thus, edge electrodes of the upper layer are rotated 90° with respect to those of the lower layer.

If a DC voltage is applied between the two electrodes of the lower layer, while the upper layer floats, the touch brings the upper layer to the same voltage as the touch point.

The touch coordinate in the direction of the lower layer is identified by measuring the voltage on the upper layer to determine the ratio of the resistance at the touch point to the total resistance. Then, electrical connections for the layers are swapped, and the coordinate of the touch point on the other axis is obtained.

- Capacitive Touchscreen -

A capacitive touchscreen panel consists of an insulator coated with a transparent conductor.

As the human body is also an electrical conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. 

In one basic technology, a small voltage is applied to the layer, resulting in a uniform electrostatic field. When a conductor, such as a human finger, touches the uncoated surface, a capacitor is dynamically formed.

The sensor's controller can determine the location of the touch indirectly from the change in the capacitance as measured from the four corners of the panel. The larger the change in capacitance, the closer the touch is to that corner.

    自带电池?还是外接的?ipad看视频不舒服,到时开电脑看看。另外不用这么客气,我又不是大佬,就是个小学生。。另外,虽然我看得懂英文,但是后两段没有中文翻译?

    想知道怎么用乐高封装内部电子元件的?胶?定制的转接件?

    楼主的帖都挺有意思啊
