Description
Technical field
LCDs technical field is the utility model is related to, particularly relates to a kind of the whole of hand-written LCDs
Machine structure.
Background technology
With developing rapidly for image display technology, education, business meetings or training field pass through frequently with electronic whiteboard, thrown
The instruments such as shadow display image on wall, not only show that person clear but also easy to operation neatly realizes page turning, mark as needed
The functions such as knowledge, editor and animation, have very strong visual performance effect.
Hand-writing liquid crystal screen (numerical digit screen) is a kind of high-end devices to be extended out in traditional hand design plate (Digitizing plate) product, main
If hand drawing board (Digitizing plate) and display are integrated, pressure sensi-tive pen can be used directly to be painted on LCD screen,
It is hand-written, because Freehandhand-drawing is felt close to being painted in common paper, than traditional Digitizing plate input more intuitively, efficiently, and therefore, liquid crystal
Numerical digit screen is more and more wide in sector applications such as animation drawing, writing signings, including as government, bank, communication, finance, medical treatment,
Animation video display, Architectural Graphing, design publication etc..Pressure sensi-tive pen is the image marking tools for coordinating hand-writing liquid crystal screen to use,
This electronic pen can not only write out word as handwriting pad, and nib has pressure sensitive, can be exerted oneself according to you big
It is small, imitate out the image write and drawn with different pressures.
Picture freeze phenomenon occurs in hand-written LCDs when using sometimes, caused by this is due to short circuit, therefore, such as
It is scheme to be solved in the utility model that what, which avoids short circuit, and traditional hand-writing liquid crystal screen is complicated in addition, and cost of manufacture is high.
