The detailed description of example embodiment

Provide the embodiment of the one or more electronic writings/drawing panel computer having in desired feature discussed above. Term " drawing " and " writing " are used as synonym in the whole disclosure. What term was both interchangeably used to mean the drawing of image, lines etc. and word, letter etc. writes both, and using the place of only one term, is of equal value with also using another term.

Electronic writing panel computer as disclosed herein is a kind of design, and it can based on such as in U.S. Patent number 6,104,448 and in U.S. Patent Application Serial Number; 12/152,729, now it is issued as United States Patent (USP) 8,228,301; With 12/220,805, now it is issued as the KentDisplays' disclosed in United States Patent (USP) 8,139,039Technology, all above United States Patent (USP) and U.S. Patent application are incorporated herein by, and it may be used for the various embodiments writing/draw panel computer drawing surface that are modified to have data capture feature. Disclosed in these referencesTechnology is by being converted to visible track over the display utilize the specific pressure-sensitivity (particularly in cholesteric polymer hybrid system) of some material by pressure of writing over the display. Additionally, disclose the relevant device with data capture ability in the PCT application that PCT application number is PCT/US10/36175 being incorporated herein by submitted on May 26th, 2010. The various example embodiment of this panel computer disclose storage function and/or data capture function are integrated into such some modes write/draw in panel computer.

A kind of mode is to use state-of-the-art data capture device (such as touch screen) to catch the information just drawn on this panel computer drawing surface simultaneously. Such as, simple, the low cost touch screen being arranged on the back side writing/draw surface can be used to, by utilizing the feature of catching of touch screen to catch the movement of stylus, as illustrated in fig. 1, be explained in more detail below.

Existence can with such as in this paper write/draw panel computer together with use to provide a lot of touch inputting methods (such as, by electric capacity, inductance, resistance, optics, acoustics and other touch input technology provide) of data capture feature. For many application, this touch screen can utilize the comparatively low resolution technology of such as low cost electric resistance touch screen, and such screen even can avoid the use of traditional transparent conductor indium tin oxide (ITO) because it can due to writing surface can be made into flexibility and be arranged on after writing surface (below). Such touch screen can use passive type stylus. Similarly, after writing surface (below) touch screen be also possible to utilize other touch screen technologies such of all sensing (electromagnetic induction (EMR)) methods of at least one preferred embodiment as discussed in this article, because sensing stylus is transparent by writing surface, it can be used to desired pressure is applied to writing surface. Resistance and inductive methods are the examples of the touch screen technology of the expection operation being not disturbed this panel computer. These technology also provide for benefit, it may be assumed that their stylus need not arrive the frenulum writing/draw panel computer.

For most of such application, the panel computer of writing/draw with integrated touch screen would be less than being likely to need to be integrated into the large-scale disposal ability that this equipment itself is interior. Panel computer drawing surface is write/is drawn in combination and touch screen will be preferably adapted to be connected to external equipment (such as computer or cell phone, for instance, then it can provide the disposal ability of any necessity, is such as used for image procossing etc.). Alternatively, some minimum treat abilities can also be arranged in this panel computer itself, to perform some basic process functions, such as A/D conversion, tiny image process, memory management functions, communication function and/or display process function, for example, therein any one or all can be arranged on desired place. The transmission controlling stored image to external equipment or the feature for displaying on integrated review display (display as additional) can also be supported. Certainly, if necessary, by adding more powerful processor (multiple) and more complicated software, it is provided that any treating capacity.

Connection between this panel computer and external equipment can be wired or wireless, as desired for intended application. Accordingly, as example, it is possible to use wired connection, direct wired connection or USB or other serial port connect, or even connect for the Ethernet of some embodiments. For wireless connections, it is possible to use WiFi, bluetooth, NFC, infrared, 3G or other connection mechanism. In certain embodiments, can be provided with line to connect and wireless connections, although it is contemplated that keep that the cost of this panel computer is low, keep it little, thin and light, and expectation reduces power consumption as far as possible, it is possible to the quantity of the feature that restriction people provide in some embodiments of this panel computer. Have that therefore operate this equipment and storage inside and/or transmission image to the minimum panel computer of only these features needed for external equipment can be preferred illustrative embodiment.

The interface that this panel computer is connected to external equipment can be set on this panel computer. Such interface can use custom protocol, or utilizes any commercially available standard in some commercial standard. Such as, realizing USB massive store classification will allow the image preserved on this panel computer to occur in the file system of host computer, and USB human interface devices classification can be used to external host computer or miscellaneous equipment show as this panel computer digitized input equipment or mouse. It addition, Wintab driver can be encoded for this panel computer so that any application being programmed into Wintab specification can use this panel computer as input equipment. Similar standard about bluetooth there is also, such as file transmission specification and human interface devices specification. Therefore, the processor of this panel computer may be adapted to management file system in the memorizer of this panel computer to support such function.

For many applications, it is desirable to, whenever possible, by utilizing the disposal ability of external equipment to significantly reduce the recordable cost writing/draw panel computer. Certainly, when needed, this disposal ability can be integrated in this panel computer itself for each application, its peripheral equipment is not expected to can use, or not there is enough disposal abilities for intended application (multiple), or provide the more self-contained panel computer more like computer.

Therefore, this panel computer can have the processor (such as microcontroller, CPU or other type of processor) of the process being incorporated in providing in the device enough. Application specific processor for realizing desired interface (such as, USB, Ethernet, WiFi, bluetooth, near field etc.) can be utilized, and can be readily available (having commercially available or customization software/firmware). Atom processor family from Intel is an example of the low power processor that can be used.

Alternately, or additionally, application specific processor, controller, A/D equipment or other electronic device can be provided with digitized, filtering or otherwise to revise the image drawn on this panel computer, and such equipment is known as together with some touch-screen applications to use and some are commercially available.

In addition, this panel computer can comprise memory devices (such as RAM, flash memory, EEPROM, hard disk drive or other data storage mechanism), and the image that display is drawn is stored in this equipment for downloading to computer or miscellaneous equipment later by it. Such memorizer can enable this equipment store hundreds and thousands of or even thousands of or more image in this memorizer. Such memory devices can be removable, such as such as digital photography and music is stored to conventional usb driver or flash card. The preferred embodiment of the example of this panel computer includes the slit of the access for commercially available removable flash memory. Therefore, in certain embodiments, removable memorizer can avoid the demand of the connection for panel computer to external equipment, because memorizer can be removed to use in miscellaneous equipment on the contrary.

As discussed above, there are many data capture options, it includes many touch inputting methods, it can use to obtain data capture function together with writing panel computer, such as pressure-sensitive touch screen, inductive touch (such as electromagnetic induction (EMR) touch screen), optical touch screen, acoustic touch screen, capacitive touch screen and other touch screen.

One preferred illustrative embodiment utilizes inductance type (EMR) touch screen of stylus with specialization (such as electronically with the active stylus of this touch screen interaction). Can being utilized and be provided in U.S. Patent number 5,136,125 for such touch panel device of such embodiment and an example of stylus, it is incorporated herein by. Two different EMR technology are available, one of them uses the stylus of the specialization comprising battery and another EMR technology uses and does not have the stylus of battery. Both technology are suitable for together with writing/draw panel computer to use. In such embodiments, touch screen is placed in below drawing surface, and does not therefore disturb drawing and display process and from without expensive transparent components. Inductive touch carrys out inductively, with any of which in operable some different modes, the existence that (electromagnetically) detect the specialized stylus of sufficiently close together touch screen. A kind of mode of detection is, the stylus of specialization is equipped with the tuning circuit carrying out vibrating and thus communicate with " detector " that detect this vibration on touch screen with electromagnetic mode. Stylus is used internal cell to power, or preferably it is powered with electromagnetic mode by receiving electrical power (such as with electromagnetic mode (such as inductively)) from touch screen itself. According to stylus how near touch screen, or the tip of stylus is to what extent pressed in this screen (such as having the stylus of adjustable tip) by user, and the lines of wider or narrower width can move through this drawing surface along with stylus and be detected electronically. Such as, wider lines can be pressed against in this screen in adjustable tip, be determined when making tuning circuit closer to touch screen detector and therefore show the connection of more powerful (or more coupling).

But, as discussed in more detail below, in the embodiment that inductance type touches, the electronic version of this image is detected (to be carried out electronically storing and/or transmitting) independent of the image drawn, because the former detection electromagnetic coupled between tuning circuit and detector, and the latter uses and shows image from stylus pressure on a writing surface. While it is true, when appropriate balance, both of which catches very similar or consistent image, and therefore user gets nowhere.

In at least some embodiments, the stylus of inductive touch can be detected, even if when it does not touch this drawing surface completely, the movement of stylus is likely to be caught electronically but does not draw any image on pressure display unit in this case. When using stylus to control the cursor on the equipment of attachment for when realizing specific function, this can be useful, and it is also likely to be needs in other cases. It is pressed in this drawing surface by stylus is more exerted oneself (deeper), thicker lines can two be plotted on this drawing surface (pressure of increase due to this stylus), and thicker lines can also be detected by this touch screen closer to this touch screen or via stylus tip relative position (such as, it may result in the adjustment that can be detected of the variable L C circuit in stylus) in stylus due to the tip (or electromagnetic assembly) of this stylus. Therefore, the width of lines can be similarly or identically adjusted in shown image and the image caught electronically.

Noting, in using the above embodiment of stylus of inductive touch and specialization (such as, active), when using the stylus of specialization, data are only caught by this touch screen. Therefore, if someone uses finger or unspecialized stylus (its can clearly purpose for not catching this image provide) or pen or pencil to draw on the drawing surface of this panel computer, so, such as, result is, image can be carried out drawing for viewing on this drawing surface, but does not have data to be collected by inductive touch, and it is captured to so there is no corresponding electronic image. This can be used to allow user to carry out drawing on this drawing surface and do not use stylus, but user can not catch this drawing in such a case electronically. This is probably needs in some cases. However, if it is desired to catch this drawing electronically, then in this case, it should always use the stylus of specialization. Therefore, when original when being likely to lose or damage, it is provided that replace the stylus of specialization.

Fig. 2 shows the schematic diagram of each layer of the drawing panel computer of the integrated inductive touch with data capture device. Inductive touch 60 is data-dapture layer, and it is placed in below drawing surface 10 to provide integrated writing and recording surface 55. Fig. 2 A shows the specific example of such touch screen 60 ', such touch screen 60 ' has to face up and has the surface mesh 63 of adapter 66 ', adapter 66 ' is used for being connected to data capture controller electronic device 201 ', and its connected device 211 is connected further to inner plate computer electronic device.

Referring again to Fig. 2, the plastic septum sheet material 42 of flat material is arranged between touch screen 60 and drawing surface 10 with the surface of " planarization " touch screen 60, it is not exclusively smooth in a lot of examples, due to the surface decussation of touch screen 60 for sensing the existence of inductive stylus (such as, as detector, and in some cases, for providing electrical power to stylus with electromagnetic mode) the existence of wiregrating 62. This plastic septum sheet material 42 is positioned at the layer between data capture (touch screen 60) layer and drawing layer (drawing surface 10), it is upper (namely that it is used for stoping the image of the wiregrating 62 of touch screen to occur in display (drawing layer) during use, stop because of " releasing by (bleedthrough) " to the pressure-sensitivity of pressure of drawing pad display), when being likely to such as such as be touched by hands or covering and slightly advanced particularly in most of wherein screen.

The alternative stoping " release and pass through " can use the coating in touch screen surface rather than plastic sheet. Such as, coating can be used as such: is coated with by blade type or is then followed by curing or hardening to smooth surface by being otherwise coated with as liquid. The sprayable material (such as coating, binding agent, Embedding Material etc.) maybe can smeared of gelation or hardening can also be used, and also be may be used for the function (being such as bonded together by each layer) added. Alternately, it is possible to use there is the sheet material of the groove mating and accepting wiregrating 62.

Typically, it is desirable to the whole thickness making this equipment is thin as much as possible, particularly, thick less than 1cm in a preferred embodiment. Obviously, drawing surface 10 is more thin, and touch screen detects pen more easy (because tuning circuit can closer to detector). It addition, relatively thin separator sheets sheet material layers is desired, its thickness is from the 2.35mm for injection mo(u)lding ABS to the acrylic good 1.4mm of work, although the thickness on the order of magnitude of the some thousandths of of an inch is probably desired (as long as feasible).

The drawing surface 10 of this example embodiment has outer writing surface 15 and includes two flexible base boards 11, and each is with the transparency conductive electrode 12 being positioned on inner surface. Pressure-sensitive liquid crystal layer 13 including the cholesteric liquid crystal material disperseed in the polymer is shelved between electrode 12. Data capture device includes the stylus 22 of specialization. Pressure from stylus 22 creates the less clearance distance 18 compared to loose distance 17 on drawing surface 10, it causes liquid crystal flowing and cholesteric tissue basically burnt wimble structure transparent, stable state is changed into planar structure reflection, stable state, when with such as by light absorbing zone 30 (such as, black layer 30) provide dark (usually black) background contrast time, it becomes the image visual for eyes. Therefore, this image is carried out drawing and being displayed to user without consumption of electric power on drawing surface 10, is formed because of the deformation of the liquid crystal that this image is caused by the pressure of stylus, and this image because of the bi-stable character of liquid crystal but lasting. Therefore, when pressure is removed, this image retains.

When the inductive touch of this example embodiment, user utilizes the pressure of the tip of the stylus 22 from specialization to draw on outside writing surface 15, to create image (without being stayed on outer writing surface 15 by material) on this drawing surface. Simultaneously, by by stylus (or the tuning circuit being located therein, or the antenna being located therein) position or place be defined as locality data, mutual by the electromagnetism of the stylus 22 of customizations and the wiregrating 62 of this touch screen, the positional information of stylus is transferred to touch screen 60 by drawing surface 10. In inductance type mode, it is not necessary to use stylus pressure information in this touch screen to carry out point data definitely. This locality data from this touch screen is transferred to touch pads electronic device (not shown) via electrode 66. Type according to the inductive touch utilized, it is possible to have multiple electrode 66.

As mentioned, for instance, at the U.S. Patent number 4 being incorporated herein by, 786,765 and 5,135, in 125, inductive touch utilizes special stylus (such as including the special stylus of the tuning circuit of inducer and the capacitor being connected in series). This stylus is generally positioned without connected to power supply or miscellaneous equipment, but has the resonant frequency of the frequency of the ripple that the coil arrangement being approximately equal to from panel computer derives from. By the electrode grid that the energy of sensing in this stylus is coupled back on this panel computer is detected stylus position on this panel computer. In commercially available Waltop equipment, it is possible to use sensor board, panel and UART connect to come and panel computer MCU device communicates.

Another example embodiment utilizes pressure-sensitive touch screen for data capture feature, thus the place of this stylus is recorded the place made on its resistance-type pad on the back side being arranged on the drawing surface 10 writing panel computer, as shown in Fig. 1. In Fig. 1, stylus 20 provides pressure to electronic writing panel computer drawing surface 10 to be similar to above with respect to Fig. 2 mode in the way of discussed.

For this optional embodiment, pressure-sensitive touch screen 40 is disposed adjacent to drawing surface 10 to provide integrated writing and recording surface 50. Drawing surface 10 is similar to above for the drawing surface described by Fig. 2, and it uses the transparency electrode 12 on flexible base board 11 (wherein liquid crystal material 13 is arranged between). When the pressure-sensitive touch screen of such as resistive touch screen, the pressure from stylus 20 is transferred to the touch screen 40 at 18 places by drawing pad 10, and it indicates its position on this touch screen or place. The state loosened is illustrated at 17 places. Resistance data from this touch screen is transferred to digital record electronic device via electrode 44. Type according to the resistive touch screen utilized, it is possible to have multiple electrode 44. This specific embodiment can be provided with relatively low cost, is relatively simple, and can be done very thin and very light in weight. Commercial touch screen can be used in this embodiment or it can be custom-designed to better with to write panel computer integrated. Optional embodiment can utilize other type of touch screen technology.

Certainly, in some alternative embodiments, by providing the luminous reflectance light background becoming transparent in response to the stylus pressure under the voltage applied exposing dark light absorption background, this image may be provided in the egative film of process described above. Due to the contrast between the part that deforms in this background and being stressed of liquid crystal, it is possible to use any embodiment shows image, thus producing desired image.

In other other embodiments, it is possible to use digital camera or other optical acquisition equipment are caught image rather than utilizes touch screen. Camera or imageing sensor can be such as have disposal ability with only identify and catch comprise this image then show on the indicator screen of Portable phone this image and store it in memory for check later panel computer writing surface Portable phone in one. This camera image can also be used to sharpen this image or otherwise such as purifies this image by removing artifact or inverted image.

For any embodiment in above-described embodiment, whole image can by being wiped from pressure-sensitive sketch surface 10 to electrode 12 via interconnection 14 applying potential pulse, such as it is being incorporated herein by United States Patent (USP) 6 herein, 104,448 and United States Patent (USP) 8,228,301 and 8, disclosed in 139,039. In the exemplary embodiment, these pulses are applied when passing through and pressing " erasing " button or receive erasing order from the equipment connected or activate erasing function by some other method. In a preferred embodiment, drawing surface 10 needs electrical power, is used only for erasing image and is put back under neutral state by liquid crystal for receiving next Drawing image. Power consumption seldom it is with or without during using the drawing stage of above-described embodiment. But, when this function is activated, electrical power catches view data electronically by being generally required for touch sensor.

Alternate embodiment can utilize some electrical power for drawing course, the function such as improved for various contrasts, there is provided inverse pattern (such as, Mode A discussed below), or part (optionally) erasing, as discussed below, but generally it due to for the bi-stable character of the liquid crystal of this equipment without any power to maintain display steady state picture picture with this.

In the additional example embodiment with data capture feature, use any method disclosed above and design, panel computer apparatus senses mapping operation during drawing course is (via data capture method, such as touch screen) and temporarily these data are stored in memory devices (it can be preferably integrated in this equipment itself, or alternately can be arranged in external equipment). (or continuously, or with the interval specified, if needing automatically to catch) activate when catching switch (such as advancing button), the data being stored in memorizer are converted to the file being also stored in memorizer with " catching " present image by equipment or external equipment. Use this acquisition procedure catching switch just as the snapshot of shooting present image is for storing. Then, user can continue to carry out drawing to revise on equipment present image, and, if necessary, catch additional image by activating to catch to switch. By this way, user can catch the progressive change to image. Certainly, at any time, user can wipe present image, and restarts the process.

In additional embodiment, it is also possible to capture time information during image capturing. Therefore, the time of each image capturing can be stored together with image, or the time can be associated with the independent data element from data capture device. For example, it is possible to catch, (x, y, t) data, wherein x is a linear dimension coordinate, and y is vertical linearity latitude coordinates, and t is the time drawing or catching this coordinate. By storing temporal information, perhaps, image or a series of images can little by little be carried out repainting in an appropriate order (and is mapped to audio recording, to re-create demonstration or lecture, for example), or by the animation that image drawing course creates, or for some other purpose. When demonstration or lecture are Tong Bu with audio recording, when beholder is writing each word, each symbol in drafting mathematical formulae, or during each lines in drawing image, they can hear what speaker saying.

Usually, when there being people, (using suitable stylus, when drawing on drawing surface if necessary), touch screen interface follows the tracks of this drawing and by draw data crossfire to processor, and wherein data are converted and are stored in memorizer. For bitmap file format, such as BMP, PNG or TIFF, the data of crossfire will be generally presented to the frame buffer in RAM. When this image is " trapped ", data can be formatted and compressed and be submitted to flash memory as specified by file format. For vector file format, such as PDF, WMF, EMF, SVG or CGM, the data of crossfire can be submitted directly to flash memory or compressed alternatively and be stored in RAM, to be transferred to flash memory when this image is " trapped " subsequently. A kind of method for such storage is to utilizeExtracting Shape as the compressed format being stored in RAM.

Note, for using the embodiment (such as shown in Fig. 2 and the embodiment of inductive touch discussed above) of the stylus of specialization, only when this stylus is used for creating this drawing, data (such as, about the information of stylus movement on pressure-sensitive sketch surface) are just caught electronically. If not use certain alternate manner of the stylus of specialization to carry out drawing image, then acquisition procedure will fail to catch this image. If additionally, use the stylus of this specialization to complete a part for this drawing, but depicting another part in some other manner, then this part only drawn by the stylus of specialization will be caught electronically. This feature may be used for special purpose, is such as used for catching the image being substantially different from this screen the image illustrated, for any amount of reason, in order to do not catch the sketch of the initial raw of drawing, for example. By providing the device being temporarily disabled touch sensor, it is also possible to realize similar functions so that some things can be drawn on screen and it is not captured memorizer, even if when using the stylus of specialization, if necessary. By closing the power supply of touch sensor or touch sensor being placed in low-power mode, this can allow to operate without image capturing when drawing with the power level that greatly reduces.

In a preferred embodiment, the image caught is stored as in the memorizer of this equipment(pdf) file. This is by the finalization Acrobat file when switch is caught in activation (adding the expense (overhead) of any needs to this document) and is then used for after by user to watch or transmitted in a flash memory by this document preservation. In at least some preferred embodiment, this image caught cannot reappear after being wiped free of continue original image on the drawing surface of this equipment, and therefore must be transmitted to another equipment for viewing. Such equipment without re-production capabilities is greatly simplified, because this drawing surface need not merge the display re-production capabilities by adding cost, complexity and quality. In this, the conductive layer in any surface of liquid crystal layer is off-patent (that is, extending continuously through the whole viewing areas of liquid crystal display).

But, in other embodiments, this equipment (such as is used for changing the technology of the state of liquid crystal layer by lifting up the device of supplied for electronic mode drawing image on drawing surface by use, such as at U.S. Patent number 5,889, disclosed in 566 or 5,644,330) ability showing image on drawing surface is provided. Alternately, this image can pass through to use the technology of the pressure-sensitivity utilizing drawing surface (such as by utilizing piezoelectric effect, for example) and by " drafting " over the display.

The drawing (image) caught can be sent to Desktop PC, notebook computer, PDA or cell phone (Fig. 7 and the Figure 10 seen below) via wirelessly or non-wirelessly link. Flash memory storage on this equipment can on a remote device in the way of similar with how processing the flash memories being inserted in such equipment accessed (such as, it can be shown as storage device) and stored Acrobat file can will be accessed for usual manner with such file and be conducted interviews. It is being described in more detail herein below with several different design performing this function for present device.

Considering the convenience of compact integrated, ruggedness, low-power consumption and use, any embodiment in the following examples of this panel computer especially can be provided to catch the image drawn on this panel computer on external equipment:

Being typically designed of compact and economic example embodiment is illustrated with block diagram in the diagram. It includes writing/draw surface 10, data capture device (such as pressure (such as, resistance-type) touch screen 40 or inductive touch 60). The circuit 300 being associated include from touch screen 40 or 60 receive data for provide (such as, by the data of crossfire) to the data capture controller 201 of general purpose microcontroller unit, have RAM general MCU205, for wiping the panel computer drive circuit 202 of the image (as described above in greater detail) on drawing surface 10, be used for rechargeable battery 203, flash memories 204 or other memorizer powered to electronic device and erasing function and for being connected to external equipment and the USB port 206 for rechargeable battery 203 is charged.

Flash memories 204 can be removable, such as by using normally used other kinds of removable flash memories (such as compact flash, memory stick, MicroSD, MMC etc.) or built-in hard disk drive in USB flash drive or computer industry (such as can be used in notebook computer, for example). Alternately, memorizer 204 can be omitted, and wherein this panel computer depends on the memorizer via the USB external equipment connected, for instance, to save quality, power and cost, in this case, image can by crossfire to this external equipment. But, this is it would be possible to it is required that this panel computer equipment is bound to this external equipment for most mapping operation to save drawing iteration, this is probably worthless in many cases.

Touch screen 40,60 with write/draw surface 10 integrate to be formed this panel computer combination write/recording surface 50,55, as being shown respectively in Fig. 1 and Fig. 2. These assemblies be then integrated in the housing to be formed this panel computer (see, for instance, the item 500 in Fig. 7). What carry out on drawing surface 10 writing or drawing by resistance-type data capture device 40 or inductance type data capture device 60 (but only when the stylus using specialization is drawn, sense if applicable) or alternatively by certain other catching method, and the data caught are converted to coordinate data by touch screen controller 201, it is by crossfire to MCU205 and is caught by MCU205. Typically, this view data is caught and is stored in by dynamically (onthefly) in RAM, until this user activates switch and catches at the image (such as pdf file, as described above in greater detail) for storing in the local flash memory memorizer 204 of image. Then each image file can be transferred to external equipment via USB port 206, such as PC, notebook computer, PDA, projector or cell phone (discussing in more detail below). If appropriate, flash memories 204 (such as SD card) can be removed to transfer data to external equipment.

Another example embodiment be figure 3 illustrates, and which are added wireless capability (such as blue tooth interface 207 or near-field communication (NFC) interface for very short-range communication) to arrive cell phone or PDA. It includes the data capture device writing/draw surface 10, such as pressure-sensitive touch screen 40 or vicarious touch screen 60 and the electronic circuit 200 being associated. Bluetooth port 207 may be used for being connected to external equipment, such as PC, notebook computer, PDA or cell phone (not shown). Alternately, NFC interface can be used to be connected to external equipment. NFC interface can substitute for bluetooth and uses, or is used for by making the step automatization enabling, match and setting up bluetooth connection that bluetooth to be supplemented. Latter event make use of the bluetooth higher message transmission rate relative to NFC, simplifies bluetooth for many users simultaneously and arranges. The alternative circuit 200 as shown in Figure 4 without external wireless ability can be provided to further simplify this equipment.

Additionally, the image being stored in memorizer can be replayed by external display (such as projector) or additional review/previewing display of integrating with this panel computer by this panel computer. For example, it is possible to arrange scroll button, it will roll through stored image and repaint them on outside or previewing display, without downloading entire set of image.

In order to reduce cost further and improve reliability, MCU205, USB port 206, touch screen controller 201 and drive circuit 202 can be replaced with a custom integrated circuit 400 (ASIC), as shown in Figure 5.

Such as small-format display (such as 2.5 " TFT, display 220 for example) can be added to any embodiment in each embodiment of this equipment for page review/preview, such as figure 6 illustrates for the ASIC embodiment of Fig. 5. Such display can also be used to roll through the image being stored in this panel computer. Other display option includes the TFT display size of bigger form, active display and electric paper display, and it includes but not limited to electrophoresis, electrowetting, microfluid and bistable liquid crystal (such as cholesteric). When can when being made into transparent drawing surface 10 except carrying out, by stylus, the occasion write, drawing surface 10 can be directly located on the top of display 220 and be optically coupled to display 220 so that watch display 220 by drawing surface 10. This provides compact devices, and wherein looking back display 220 can be equally big with drawing surface 10. Look back display 220 and be not limited to the content that display records from drawing surface 10, but be displayed for other content, such as photo, books, video etc. Look back display 220 to can also be used to provide the template (such as lined paper, form, test or basketball court) after drawing surface 10. In such a system, it would be possible to can preserve by produced composograph that template is combined with the data caught on drawing surface. Including cholesteric LCD without back paint drawing surface 10 be suitable for such application. Therefore, the more multi-functional panel computer with display 220 can be provided in an alternate embodiment of the invention.

Battery 203 in Fig. 3, Fig. 4, Fig. 5 and Fig. 6 can utilize rechargeable lithium polymer battery (or other rechargeable technology) and/or solaode in this design, and it may be used for additional rechargeable battery is charged. Lithium polymer battery can charge by solaode or by USB port, for example. The ready-made IC of the example for being charged from USB port originates from the bq24050 of Texas Instrument, and it is described as " 800mA, SingleCellLi-IonandLi-PolBatteryChargerWithAutomaticAdap torandUSBDetection ". Such design is likely to last for several years without any change or change parts.

The embodiment of additional display capabilities is provided

There is the panel computer of dual imaging display

For such feature, a kind of option is the technology (as looked back in " CholestericLiquidCrystalsforFlexibleDisplays " the 17th chapter of Ed.G.Crawford (john wiley & sons 2005) J.W.Doane and A.Khan) using the state for changing liquid crystal layer electronically. This example apparatus has dual-use function, one, as providing the electronically addressing display of digital picture and another is as writing panel computer, can use such as the pressure-sensitivity on the drawing surface 615 with substrate 611 described by other place in the disclosure and drawing image over the display wherein. The image write also is digitized for memorizer and further uses. This be figure 13 illustrates, and in fig. 13, dual-use function display 670 is used as pressure-sensitive to write panel computer and by being attached to the character display that the drive circuit 674 of electrode interconnection 673 addresses by what address with the pressure of the stylus 622 of tip. Two electrodes 671 and 672 or only in these electrodes will be patterned, wherein pressure-sensitive cholesteryl liquid crystal dispersion 613 is arranged on therebetween. When passive addressing display, by the form patterning with such as row, electrode 672 is patterned (as in the United States Patent (USP) 5,889,566 and 5 being incorporated herein by by the form with orthogonally oriented row electrode 671, described in 644,330). The driving voltage with bi-polar waveform (as described in United States Patent (USP) 5,644,330) or monopole wave (as described in United States Patent (USP) 5,889,566) is placed on electrode 671 and 672. Additionally, drive circuit 674 can be used to the image that erasing is created by the pressure of stylus 622. In fully-integrated equipment 655, dual-use function display 670 combines for catching the image write on equipment by stylus 622 with touch screen 660. Optional complanation layer 642 occupies the space between display and touch screen. In order to provide and the contrast of the image on display 670, between display 670 and following touch panel unit, there is opaque layer or semitransparent layer 630. Next assembly when using inductance type touch sensor is optional planarization layer 642. But, alternative embodiment can use other type of touch sensor, and it can as described previously for as described in similar assembly.

Alternately, electrode 671 can not be patterned, and electrode 672 can be (or vice versa) of being patterned and carried out processing (described in the United States Patent (USP) 6,819,310 being such as incorporated herein by) with the form of active matrix. In this case, drive circuit 674 is by voltage waveform (such as described in 6,819,310 patents) offer to electrode interconnection 673. Dual-use function electronic displays is mutually integrated with the touch screen 660 with wiregrating 662, electrode 666, dividing plate sheet material 642 and light absorbing zone 630 with pressure-sensitive display of writing, as mentioned above.

This template can be a kind of form, and user is with its hand-written answer of blank space in the form caught and result. It can be the diagram of football pitch or basketball court, and wherein user (coach) competes for athlete's Freehandhand-drawing in template. Alternately, this template can be that simple thing (such as parallel lines) is to help user to carry out text writing (such as lined panel computer). The image of this template can be stored with in final composograph with the hand-written image caught. Another potential application of dual-use function equipment can be interactive reader, and the key concept in text is underlined or adds figure by student's download text electronically or figure and student accordingly. Then hand-written change can be caught by student and be reserved for further research. Other application many can come from this dual-use function equipment.

There is the panel computer of independent electronic displays

In relevant embodiment, it is stored in the digital picture in memorizer or the digital picture from other source can be shown by external display or the display integrated with panel computer, image can be shown, for example by drawing/writing surface. Figure 14 illustrates and is write panel computer 710, substrate 711, pressure-sensitive cholesteryl liquid crystal dispersion 713 and the equipment 755 that forms of the electrode 712 integrated with the character display 780 addressed electronically by what have a writing surface 715. Display 780 preferably reflective display, preferred technology is that electrophoretic display is (such as in the United States Patent (USP) 5 being incorporated herein by, described in 930,026) or cholesteric display (such as described in the book " CholestericLiquidCrystalsforFlexibleDisplays " of the Ed.G.Crawford (john wiley & sons 2005) being incorporated herein by). Other reflective display technology as known in the art can also be used, as luminescence or backlit display can be used. Character display 780 is driven electronically by the drive circuit 782 of the electrode with the display being coupled to interconnection 781. Display 780 is touch screen 760 and the electrode 766 with wiregrating 762 below, all as described above, it is preferred that technology is inductive touch or resistive touch screen. Cholesteric is write panel computer 710 and is addressed with the pressure of the stylus 722 with tip and carried out electronically wiping (such as in United States Patent (USP) 5 with the erasing circuit 783 (with interconnection 714) using the waveform that this planar structure is driven into burnt wimble structure, 889,566 or 5, described in 644,330). Writing the interface 784 between panel computer 710 and electronic displays 780 is mate the material of refractive index of two equipment in their interface or it can be translucent optical filter, with the contrast (such as in the patent application serial numbers in submission on May 22nd, 2012 being incorporated herein by for described in the U.S. Patent application of 13/477,638) strengthening the image write on this panel computer. In the present embodiment, advantage is similar to embodiment above, and wherein display can serve as template for this panel computer that the wherein image write on panel computer is captured. The image write can pass through itself be saved to file or be saved as the composograph combined with this template by the image write. This image or previous image from memorizer can be replayed on panel computer.

Note, for any example in these examples, any assembly being similar in the assembly of above-mentioned (panel computer for not having electronical display ability designs) those assemblies can use the design similar or identical with those assemblies described in upper part. The image drawn electronically over the display can obtain in the image from following item: previously caught and be stored in the image of inside (or being stored in outside) by panel computer, or the image otherwise provided for display (such as passing through external equipment), for example, or the image in supporting the system of networking of multiple panel computers, for instance be described below.

Example apparatus is applied

Fig. 7 shows the example plots equipment panel computer 500 with capture ability being connected to computer 600 via USB interface 510. User uses the stylus 22 of specialization to draw on the outer writing surface 15 of panel computer 500, and it is likely to just use inductive touch capture ability. This example plots panel computer 500 has two interface button, erasing button 501 and catches/wake up button 502. Indicator 503 lets the user know that both: when this equipment is actively (such as by stable luminescence), and when this equipment is catching image (such as by glimmering, for example). In order to save electric energy, this equipment has sleep pattern, and wherein it by closedown touch screen and catches electronic device, in order to reduce power consumption. User can catch/wake up button 502 by pressing and wake this equipment up. Additionally, when user wants to catch the present image on this equipment, user can advance and catch/wake up button 502 to trigger this acquisition procedure. Can also arranging locking switch, it is by the image on locking drawing surface so that it can not be wiped free of until locking switch is released. Certainly, independent button may be used for catching and arousal function, if necessary. Noting, variable line width is illustrated on both panel computer 500 and virtual monitor 515, and they are configured in mode as herein above discussed in detail.

On computer 600, application can be set, it allows user in real time (or close in real time on virtual screen 15', it is unconspicuous or negligible for making time delay) see the identical image (as long as this image is drawn by the stylus 22 using specialization) just drawn on plotting equipment 500, as represented shown in 515 by the figure of equipment 500. By using cursor of mouse to activate virtual push button, for example, virtual erasure button 501 ' wakes up with virtual/and catching press-button 502 ' can be made into and operate in the way of identical with the corresponding physical button on equipment 500. Therefore, the application that computer 600 runs can control the function of actual plotting equipment 500, such as orders it to wipe drawing surface 15 while virtual screen 15' is wiped free of. Visual indicators 503' can to the instruction of this equipment of user operation in the way of being similar to indicator 503.

Alternately, it not drawing image in real time on computer 600, but panel computer 500 only can make computer 600 draw this image on the contrary after catching press-button 502 is pushed into catch this image. It is selectable on panel computer 500 or computer 600 that such function can be made into user.

The additional feature that can be arranged on computer interface includes allowing the view adjusting virtual unit 515 and other to arrange (such as by using pop-up window). Computer interface can also be used to configuration plotting equipment 500. For example, it is possible to be arranged on the clock that this equipment file system uses so that new image file can have the establishment timestamp being associated. It addition, plotting equipment 500 may be configured to directly preserve image with preferred form (such as PDF, WMF, TIFF, BMP, SVG, cgm, PNG or JPG). Whether whether another interfaces windows may be used for user and chooses whether to preserve this image in virtual screen in this locality, or use e-mail applications Email to send this image, or utilize this image to perform certain other function. Other function such can include uploading to this image social network sites (such as Facebook or Twitter). It can also include uploading to this image the service (it can automatically synchronize your notes at your computer equipments (such as smart mobile phone, personal computer, panel computer etc.) all) of such as Evernote or it imports to MicrosoftOneNote (similar function is supplied to Evernote by it). Be stored in the image file in the flash memories of panel computer equipment 500 can be accessed for replicating, open, deletion etc. (as the file on any removable disk).

The application (such as can be provided for installing plotting equipment 500, or be available for being downloaded) run on computer can provide system tray for the various functions (including battery capacity indicator and the appliance icon of the active volume of rechargeable battery for display device 500) of this equipment easily accessed. The display indicator when this equipment is not connected can also be set.

It is further noted that the color drawing feature described in cited application can be also used for the drawing panel computer with data capture. It addition, the selective erasing of each several part of this also described in this application drawing can be also used for the panel computer with data capture feature.

Therefore this panel computer equipment be made into useful (plotting equipment as on PC), is easier to than drawing on panel computer equipment when upwards look at PC monitor because drawing with stylus when look at pressure sensitive display. Therefore, lift up the image for localization on drawing surface and provide the obvious advantage exceeding the equipment that can not so do.

Additionally, this connection may be adapted to use stylus for general mouse function, such as drag and fall rather than draw, in this case, it is possible to it would not be desirable that, it is seen that the such action drawn on drawing pad. Therefore, this equipment can have more than one operator scheme. In the first mode of operation, the image such as drawn with the stylus of specialization on drawing surface is shown on a surface. In another operation mode, in order to stop such action to be drawn on drawing pad, first this drawing surface can be wiped free of and then selective erasing function (being described in more detail below) will by enable state maintenance. Can switch on use equipment or activate such function by entering the operator scheme on menucommand. Under such operator scheme, therefore each thing drawn by stylus by coupling background color and is sightless (namely it is wiped continuously when drawing). According to this operator scheme, when enabling selective erasing function, it is likely to need voltage at drawing pad electrode two ends. Alternately, higher voltage waveform can be successively applied to drawing pad electrode, whole drawing surface is erased into burnt cone (dark color) state by it, or can use the another higher voltage waveform of the liquid crystal keeping the whole drawing surface with plumbness.

Therefore this panel computer equipment can have double duty. It can play the effect of input equipment for when being connected to computer (in this case, for showing on drawing surface, image can maybe can be not needed) to draw or control cursor or this panel computer and may work as note taking/plotting equipment when being not linked to computer, it stores the image in onboard memorizer. This equipment with the single purposes of such as figure input panel computer is contrasted, its input equipment only serving computer or record notes but not effect to the useful electronic notebook record system based on pen and paper of computer entry device.

It addition, for additional example embodiment, the low-cost equipment being always bound to PC can omit battery and flash memory.

Selective erasing ability

In on May 26th, 2010 submit to and the patent application serial numbers that is incorporated herein by be 12/787,843 U.S. patent applications disclose a kind of for allowing the selective erasing of the image drawn without the design of the double mode drawing pad 10 of the broken colour wiping whole image as discussed above. In this design, provide " Mode A ", the wherein pressure of the use stylus with tip, via the liquid crystal with burnt planar state facing to the BACKGROUNDLiquid crystal with flat state on this pad drawing image, and provide " Mode B ", wherein use pressure, on this pad, draw coloured image via the liquid crystal with flat state facing to the BACKGROUNDLiquid crystal with burnt planar state. Mode B is considered the negative-appearing image of Mode A. Above-mentioned without in the embodiment of selective erasing, principal mode is Mode B.

By only using, two kinds of colors (foreground and background colour) are with drawing image on drawing pad and erasing image, and this multi-mode mode can be used in another example embodiment of this instant equipment. In such devices, by this operator scheme being changed into another kind of pattern and then can write each several part that background colour wipes the drawing shown on drawing pad of use a kind of pattern drafting in this drawing, thus substantially erasing the image drawn, such as United States Patent (USP) 8, in 139,039 in greater detail.

Therefore; such as; the equipment using dual-mode operation can operate the normal drawing for B in mode, and it need not at the voltage of drawing pad two ends (that is: via the electrode 12 writing panel computer 10 of Fig. 1 and Fig. 2 at liquid crystal two ends) during using the mapping operation of pressure (such as via the pressure of the tip of stylus). Because it reducing the power consumption during drawing course, so it is usually preferred operator scheme.

But, if the user desired that a part for the image shown by erasing, this drawing pad can be switched to Mode A for selective erasing, and wherein, voltage is applied to the electrode 12 writing panel computer 10 during erase process. This can be completed by following item: by activating the push-on switch or other actuator being arranged on equipment, or by certain menu item on the activation connected remote equipment of this panel computer or actuator, or by sensing certain change of stylus, or by activating the switch on stylus, any mode in these modes can cause the change detected in the resonance circuit of this stylus, thus causing this panel computer that from Mode B, its operator scheme is changed into Mode A.

Then, user can pass through to apply pressure to this part of this image and (such as by using the eraser tip of stylus, or the finger of even user, for example) wipes the desired part of shown image. Substantially, user is rewriteeing the part drawn of this image with background colour, thus erasing this part of this image. Then this panel computer can be set to and return to Mode B for further drawing. This can such as by using manual actuator or having been returned to this drawing tip orientation complete by sensing this stylus.

Such equipment will still have the erasing ability for wiping whole image, as mentioned above. Usually, do not provide voltage for the drawing during Mode B at the two ends of liquid crystal, but, when A draws in mode, voltage must be applied in the two ends of liquid crystal, and therefore, for most mapping operation, by Land use models B, power can be saved, it does not consume power completely, and (compared to Mode A, it is being write or is really consuming power during erase process. But, once A writes or wipes image in mode, it is not necessary to the voltage of electrode 12 of Fig. 1 and Fig. 2 to show the image of gained. It is placed in liquid crystal two ends and is substantially below voltage for fully wiping this image (such as ,��5V right��20V) for the voltage of selective erasing.

Fig. 8 shows the example embodiment of the panel computer 520 realizing this aforementioned capabilities. In image 101, normal mode B is provided for using the stylus being placed in such orientation 121 to draw on panel computer 100: the drawing tip of stylus contacts with panel computer drawing surface. Image 102 display is switched to the Mode A erasing end for the stylus being used in orientation 122 to wipe the panel computer of the part of this image, and image 103 returns to the normal Graphics Mode of the drawing tip using the stylus returning to orientation 121.

As an alternative, drawing can be used Mode A to complete and be wiped and Mode B can be used to complete. Fig. 9 shows the such alternate embodiment for panel computer 540. In image 151, normal mode A is provided for using the stylus being placed in such orientation 161 to draw on panel computer 150: the drawing tip of stylus contacts with panel computer drawing surface. Image 152 display panel computer is switched to the Mode B erasing end for the stylus being used in orientation 162 to wipe the part of this image, and image 153 returns to the normal Graphics Mode of the drawing tip using the stylus returning to orientation 161.

Such selective erasing can be caught by coming in a similar fashion electronics. Once panel computer knows that it is in erasing mode, then on panel computer by the touchscreen senses below drawing pad to the image drawn have some modes to carry out electronics to catch this erasing. Such as, can be used to rewrite the original image with background colour with the part wiped of " new " image of background colour, thus erasing the desired part of this original image. If image is used vectogram to store, then this is useful especially. Alternately, if this original image is stored as bitmap, then the bitmap of new rewriting can be used or this original bitmap can be modified to show this erasing.

Concept above can be modified so that panel computer can use multilayer liquid crystal to show the image of colour, such as what discuss in applying for 12/787,843. In such embodiments, any layer in each layer can independently in mode A or Mode B be operated, cause some patterns be arranged to allow for color drawing and erasing ability extremely complex setting.

Input equipment is applied:

The alternate embodiment of panel computer equipment specifically described herein can be utilized so that the operation of panel computer equipment is that input equipment is to support various products & services.

For an example, drawing panel computer equipment is used as input equipment and uses in various computer utilitys for being connected to computer. Such as, cursor operations can be mouse, digital converter or trackball interface by this equipment so that this plotting equipment can be used to select various computer function, such as selects menu and activator button, for example. Further, this equipment can combine with mapping software so that is not use trace ball or mouse, and this user (such as uses cursor, for example) can use the drawing should for drawing. This user can select current color in the application, and then uses this cursor to carry out drawing image to utilize the drawing function of the mapping software being installed on computer.

This drawing panel computer equipment even may be adapted to the drawing lines allowing rugosity to differ. Such as, by more forcibly pressing on drawing surface, stylus is closer to the inductance type touch pads of panel computer plotting equipment, and, should closer to position can be the information relevant with the pressure being applied to drawing surface by electrode grid detection, and, therefore, it is converted into thicker lines. Another replacement scheme includes use variable L C circuit in stylus, make the resonance that advancing in the moveable tip on stylus changes lc circuit (such as by changing the setting on variable condenser, variable inductor or rheostat, for example), it can also be interpreted the information relevant from the pressure being applied to drawing surface and therefore different line thickness. Such variable L C can also be used to the function on amendment computer, the such as propelling when operating as click and the lighter propelling when having difference in functionality, for example. Alternately, multiple stylus with different resonant frequencies may be used for different functions, is such as used for activating particular color, line roughness, filling shape, etc.

Alternatively, or in addition, the velocity solution on stylus traverse drawing surface can be interpreted as the intended line roughness of instruction by this equipment so that plotting speed causes thinner lines faster, and slower plotting speed causes thicker lines, for example.

The line roughness recorded can be tuned to mate the rugosity of the lines drawn over the display based on one or more in pressure, speed or temperature, as discussed in detail above. Such as, Fig. 7 is shown in the thicker lines 521 and thinner lines 522 drawn in panel computer 500. In this example embodiment, the difference of line roughness is also reflected on telecreen 600 further, although this is all this situation without need for whole embodiments. Similar rugosity difference also figure 10 illustrates, and wherein three lines of different rugosity are displayed in both panel computer 550 and external screen 555.

As another replacement scheme, drawing panel computer equipment can serve as input equipment for providing demonstration on computer screen, projecting apparatus screen, panel computer, electronic whiteboard etc., make lecturer or other spokesman that this equipment can be used for real-time or close to real-time communication, can be used for writing mathematical formulae by teacher like blank or blackboard, for example. It is similarly to shown in Fig. 7 and application recited above, simply panel computer will need not write the virtual version of panel computer, but write big display watch being used for for by spectators, as shown in Figure 10, wherein panel computer 550 is shown as wirelessly connecting 559 to projector 552 for projecting image on screen 555 for the image (by user directly on screen 555) shown on be plotted in panel computer 550. The bluetooth wireless connections 559 that such system can be used between the computer of panel computer 550 and (being interiorly or exteriorly linked to) projector 552 realize, wherein, computer uses the data from this equipment to generate the image shown on screen 555 by projector 552.

In such embodiments, it is desirable to the image drawn on panel computer 550 is in real time or close to being displayed on screen 555 in real time so that there is only small delay when showing image on screen 555. Such in real time or close to real-time display in order to adapt to, it is to be expected that, directly by from the draw data crossfire of panel computer 550 to projector 552, as any intermediate steps, such as first storage image in the memorizer on panel computer, it is possible to the real-time rendering of interference screen 555 epigraph. Noting, variable line width is illustrated on both panel computer 550 and screen 555, and they are all configured in mode as herein above discussed in detail.

Therefore, memorizer storage function can be completely eliminated in this embodiment or memorizer store before or can complete draw data crossfire to projector 552 concurrently so that in the crossfire of data, there is not obvious delay.

In alternate embodiment shown in fig. 11, panel computer 560 has an operator scheme, and wherein image is not plotted on panel computer, as discussed in detail above. In this example embodiment, panel computer 560 does not show by stylus just at the image drawn with panel computer basis, draws although this image is displayed on screen 555. This pattern can be activated by the switch that user activates on panel computer 560, for example.

Figure 12 shows that example is applied, and plurality of panel computer equipment 565a, 565b and 565c can be simultaneously used for drawing image on screen 555, wherein a part for the shown composograph on the home screen of each panel computer contribution. This allows the cooperation between many different users. Wherein user can be supported similarly by the application using a panel computer equipment part as conferencing technology ability to carry out long range positioning, and wherein each user can have themselves the external screen showing this composograph. Certainly, panel computer has in the application of integrated electronic display (as described in chapters and sections above) wherein, the image drawn by other user can also be displayed in each in the platform of networking, or alternatively, show this composograph basic display unit (or long-distance user see other display) is upper.

The such demonstration form using above example or its replacement scheme can include showing such image on electronic whiteboard, television set or other type of display. It is possible to further utilize the computer of networking or the projector of long range positioning so that the people at remote site place can watch result in the local monitor such as supporting video conference or screen, for example. For spokesman, the advantage with local screen is in that, at image just when drawn, spokesman can see this image on input equipment (this panel computer), and therefore, it is easier to continue when they interrupt (shortcomings of many existing products). In video conference, if more than one user is equipped with drawing panel computer equipment, then they can draw with themselves ink color on blank with each user collaboration, for example. The amendment of such panel computer it may be that change over the ratio of width to height more mating display screen by the ratio of width to height of panel computer, or allows to change the orientation of panel computer based on display screen.
