It is usually input using a touch screen. Due to the inconvenience of its input, it is basically not capable of office work. This is the biggest problem facing tablet PCs at present.
为了解决上述问题，目前市面上有蓝牙外挂式键盘，通过此种键盘可以克服平板电脑的输入瓶颈，但现有技术中的蓝牙键盘都是采用传统剪刀脚式键帽结构，剪刀脚式键盘其因结构原因整体厚度降不下来，所以整个成品较厚，携带不够方便，这样就不能突显平板电脑最初设计时的 “轻、薄、携带方便” 等优势。In order to solve the above problems, there is a Bluetooth external keyboard on the market, and the input bottleneck of the tablet computer can be overcome by the keyboard, but the Bluetooth keyboard in the prior art adopts the traditional scissors-foot type keycap structure, and the scissors-foot type keyboard Due to the structural reasons, the overall thickness cannot be lowered, so the whole finished product is thick and not easy to carry, so that it cannot highlight the original design of the tablet. "Light, thin, easy to carry" and other advantages.
同时，市场上也推出了触摸式键盘，这种键盘虽然可以做到轻薄，但其是采用触摸式输入方式，在操作时完全没有输入手感，输入时感觉就像在一个平板上打字，当按下按键时有没有功能输入操作者完全不清楚，而且因为键盘面积小，按键排布紧凑，输入时手指很容易误打。At the same time, the touch-sensitive keyboard has also been introduced on the market. Although this keyboard can be made thin and light, it adopts the touch input method, and there is no input feeling during operation. It feels like typing on a tablet when inputting. It is completely unclear whether there is a function input operator when the button is pressed, and because the keyboard area is small, the button arrangement is compact, and the finger is easily mistakenly hit when input.
