LIQUID CRYSTAL HANDWRITING BOARD, HANDWRITING SYSTEM, AND CONTROL METHOD FOR HANDWRITING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18282985 titled 'LIQUID CRYSTAL HANDWRITING BOARD, HANDWRITING SYSTEM, AND CONTROL METHOD FOR HANDWRITING SYSTEM

Simplified Explanation

The liquid crystal handwriting board described in the patent application includes a liquid crystal panel, a photosensitive assembly, and a control assembly. The liquid crystal panel consists of two substrates, the photosensitive assembly contains multiple photosensitive elements, and the control assembly is responsible for detecting position information of light irradiated to the panel and supplying voltage to erase specific pixel regions.

• Liquid crystal handwriting board components:

   - Liquid crystal panel with two substrates
   - Photosensitive assembly with multiple photosensitive elements
   - Control assembly for position detection and voltage supply for erasure

• The control assembly determines position information of pixel regions for erasure by detecting light irradiated to the liquid crystal panel and supplying voltage to the pixel electrodes in those regions for erasure.

• A voltage difference is created between the pixel electrodes in the region for erasure and the common electrode.

Potential Applications

The technology described in the patent application could be used in: - Electronic writing tablets - Digital signage - Interactive whiteboards

Problems Solved

This technology solves the problem of easily erasing content on a liquid crystal panel without the need for physical erasers or cleaning materials.

Benefits

- Environmentally friendly (reduces paper waste) - Convenient for users (quick and easy erasing) - Cost-effective in the long run (reusable writing surface)

Potential Commercial Applications

Optimizing Liquid Crystal Handwriting Board Technology for Electronic Devices

Possible Prior Art

Prior art may include similar liquid crystal display technologies used in electronic devices for writing and drawing purposes.

How does the control assembly detect the position information of the target light irradiated to the liquid crystal panel?

The control assembly likely uses sensors or detectors to capture the position of the light on the panel.

What is the expected lifespan of the liquid crystal panel in this technology?

The lifespan of the liquid crystal panel may vary depending on usage and quality of materials used. Regular erasing and writing may affect the longevity of the panel.
