Detailed description of the invention
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
In conjunction with Fig. 1, the present invention provides a kind of method by handwriting equipment to display device entering handwritten information, comprises the following steps:
Step 1, display device includes display screen and display control unit；Handwriting equipment includes handwriting pad and hand-written control unit；Display control unit sets up communication connection with hand-written control unit, for instance, display control unit sets up communication connection by bluetooth, WIFI or USB and hand-written control unit；After setting up communication connection, display control unit obtains shape and the size in the hand-written district of connected described handwriting pad by the 1st preset rules；
The display device that the present invention relates to, for arbitrarily having the equipment of display screen, for instance, it is possible to for the smart machine such as mobile phone, panel computer.
In practical application, display control unit can adopt shape and the size in the hand-written district of the following two method connected described handwriting pad of acquisition:
Method one:
Display control unit pre-stored following handwriting equipment parameter information: the shape in the hand-written district of many group handwriting equipment models and correspondence and size；After described display control unit sets up communication connection with hand-written control unit, display control unit, by this communication connection, reads described handwriting equipment model；Then, described handwriting equipment parameter information is searched, it is thus achieved that the shape in the hand-written district of the described handwriting pad being connected with described display control unit and size；
Method two:
Display control unit is after setting up communication connection with described hand-written control unit, and described display control unit sends the request message obtaining hand-written district shape and size to described hand-written control unit；Described hand-written control unit, after receiving this request message, sends described hand-written district shape and size to described display control unit.
Step 2, described display control unit generates handwriting input display box by the 2nd preset rules；User operation display control unit drives display screen, and at least one input frame activates mark to make display screen show；
The handwriting input display box that this step generates, the actual handwriting input display box for being initially generated.
In practical application, display control unit generates handwriting input display box by following rule: described display control unit reads shape and the size of display screen viewing area, then, generate, girth identical with the described display screen viewing area shape handwriting input display box less than or equal to described display screen viewing area, that is, display control unit generates a handwriting input display box after the scaled down of display screen viewing area, specifically reduce ratio, setting flexibly according to the actual requirements, this is not limiting as by the present invention.
Step 3, described display control unit judges whether be currently real-time Transmission pattern, if real-time Transmission pattern, then performs step 4-step 8；If not real-time Transmission pattern, then it is off-line transmission mode, performs step 9；
For convenience of the understanding to subsequent step, carry out the real-time Transmission pattern that the present invention relates to and off-line transmission mode simply introducing herein:
Under real-time Transmission pattern and off-line transmission mode, all need to detect whether in real time end of input event, end of input event refers to: when generation end of input event being detected, namely the end of input to current handwriting input display box is thought, such as, one student is answered the handwriting input display box of paper, when there is end of input event, namely it is believed that student is complete to current question answer.Concrete end of input event can set according to the actual requirements, there are several end of input event in the step 4 below.
In the present invention, the main distinction of real-time Transmission pattern and off-line transmission mode is: under real-time Transmission pattern, handwriting pad passes through writing pencil in real time at the person's handwriting coordinate of handwriting pad institute written handwriting to what display panel transmitted for user, and, under real-time Transmission pattern, display panel end is configured with handwriting input display box and input-buffer frame simultaneously, handwriting input display box is all identical with hand-written district shape with the shape of input-buffer frame, but, handwriting input display box is the display box after hand-written district scaled down, show after the new person's handwriting point scaled down that in real time hand-written district can be produced, for a kind of preview pane；And input-buffer frame is display panel running background input-buffer frame, it is possible to for the buffer memory frame after hand-written district scaled down, it is also possible to the buffer memory frame after amplifying for hand-written district equal proportion, it is also possible to identical with the size in hand-written district.As a kind of optimal way, input-buffer frame is the buffer memory frame after hand-written district equal proportion is amplified, when the buffer memory frame that employing input-buffer frame is after hand-written district equal proportion is amplified, its principle is: the new person's handwriting point equal proportion produced in hand-written district in real time is shown to input-buffer frame after amplifying, once after there is end of input event, after the handwriting image that input-buffer frame stores is carried out picture cutting, then zoom to the person's handwriting picture that applicable display screen shows, and finally show.Adopt this kind of mode, the precision of the final person's handwriting picture that display screen shows can be improved, improve the effect of the final person's handwriting picture that display screen shows.
And under off-line transmission mode, when user is write by handwriting pad, in writing process, display panel one end does not show written handwriting, and only when there is end of input event, hand-written control unit generates handwriting pad person's handwriting picture, and handwriting pad person's handwriting picture is sent to display control unit, after handwriting pad person's handwriting picture is carried out picture cutting by display control unit, then zoom to the person's handwriting picture that applicable display screen shows, and finally show.
The strengths and weaknesses analysis of real-time Transmission pattern and off-line transmission mode is as follows:
The transmission of off-line transmission mode is picture, only the transmission primaries when there is end of input event, if the user writing time is longer, the more power saving of off-line transmission mode, off-line transmission simultaneously can also carry out when closing display panel.And the transmission of real-time Transmission pattern is person's handwriting coordinate, transmitting data to display panel in whole writing process, display panel necessarily be in open state always.
On the other hand, the picture owing to transmitting under off-line transmission mode is the solid-color image generated by handwriting pad, malfunction.And under real-time Transmission pattern, owing to being transmission of coordinate, and draw on the display panel, so relatively flexible, such as can change the color that coordinate is drawn, thus drawing the image of colour.It addition, under off-line transmission mode, it is necessary to transitive graph picture, consuming time longer.And under real-time Transmission pattern, it is only necessary to preserve the image drawn, consuming time shorter, it is possible to reduce the time exited, promote Consumer's Experience.
