Description
Technical field
The utility model relates to a kind of liquid crystal handwriting screen, relates in particular to a kind of liquid crystal handwriting screen structure of improving liquid crystal handwriting screen linearity of ambient antenna.
Background technology
General electromagnetic type handwriting pad is specific or because of the magnetic field of button by the variation frequency of district's generation by writing pencil emission (generations), via the desirable absolute position of writing pencil in the antenna array loop that get of specific antenna loop design, and then make through the design of electronic circuit, software and to form the motion of writing pencil on the antenna array loop, and change in location and to can be used as the function that pointer such as slide-mouse or writing pencil are write input.
General handwriting pad all passes through obtains many strip antennas signal on the matrix (transverse axis X-axis and Z-axis Y-axis), obtain power as three inductions, and then the signal power of calculating and differentiate each strip antenna forms transverse axis, and the fixed position (being commonly called as coordinate points) of Z-axis with respect to the position distance value from the signal of writing pencil at a distance of certain distance and adjacent antenna.
Because the electromagnetic type handwriting pad of selling on the market allows the periphery of that strip antenna of upper and lower, left and right can design the many strip antennas that exceed the workspace in the space that is assigned of antenna plate and shell and perform region, with the accurate signal comparison that obtains four marginal line areas and calculate sideline sense from the signal power of writing pencil, and at a distance of certain distance, no matter be inboard (workspace) or LHA aerial signal power, compare and precisely calculate the position (coordinate) of four each antenna field of edge, promptly each of writing pencil place corresponding with level and Z-axis coordinate points.Yet, because the handwriting pad Antenna Design is put into the LCD module, promptly preceding demonstration liquid crystal display (containing module backlight) interior, and control circuit or brandreth between the time, handwriting pad adds the combination of liquid crystal display, promptly general so-called tablet monitor (handwriting screen-electromagnetic type).This kind design is embedded in the middle of the LCD module because of the antenna plate of handwriting input, all around limit at the LCD module when using by the front writing pencil because of LCD module front chase, make that the electronics field signal of writing pencil can't be as about handwriting pad or the handwriting screen zone line, or about respectively to have three above antennas to do signal strong and weak relatively, go up most and form, down, a left side, the signal of the reception writing pencil of right each strip antenna induction zone is because of the restriction of the chase around the LCD module front end, and the restriction of LCD module overall dimensions can't strengthen antenna size in the LCD module, add and go up most, down, a left side, right antenna.Under aforementioned several restrictions and form that the LCD screen adds electromagnetic type handwriting pad antenna and the handwriting screen that forms can't can lose smooth-going function at the handwriting functions in each strip antenna district of upper and lower, left and right, promptly the linear function of so-called handwriting functions is not normal.
