When the bistable liquid crystal film is in the FC state, the bistable liquid crystal film is in the recording state, and at the same time , the display screen body is energized to emit light, and at this moment, the ...

AI Technical Summary

Problems solved by technology

It mainly uses the touch screen to sense the movement trajectory of the contacts, but this kind of display device is limited by the working principle of the touch screen. When writing, drawing or similar actions, the touch screen cannot completely capture the original handwriting, and its use experience is poor.

[0006] Handwriting tools made of bistable display film can capture and retain the original handwriting, which can greatly enhance the experience of writing, and has many advantages such as convenient operation and paper saving, but the technology of bistable display film is currently Only in the field of making handwriting tools, there is no product and technology that can superimpose bistable display film and display to improve user experience, and this is the main shortcoming of traditional technology
