The future pixel is deactivated if pen input information is not received on the activated pixel for a predetermined amount of time.
Description
Technical field
The disclosure relates generally to the field of electric paper display.More specifically, the present invention relates to pen tracking and low latency (latency) display update on the electric paper display.
Background technology
Recently, some provide the characteristic of some paper in the display that can the electronics mode upgrades technology has been proposed.The characteristic of the paper of some expectations that the display of this type is attempted to realize comprises: low-power consumption, flexibility, wide visual angle, low cost, light weight, high resolving power, high-contrast and indoor and outdoors are readable.Because these displays attempt to imitate the characteristic of paper, so, in this application, these displays are called electric paper display (EPD).Other title for the display of this type comprises: type master mode (paper-like) display, zero energy (power) display, Electronic Paper (e-paper), bistable and electrophoretic display device (EPD) (bi-stable and electrophoretic display).
EPD anticathode ray tube (CRT) display or LCD (LCD) have relatively disclosed: usually, EPD needs less power, and has higher spatial resolution; But it has the shortcoming of slower renewal rate, gray level control not too accurately and lower color-resolution.Many electric paper displays are current only to be GTG (grayscale) equipment.It is available that color devices is just becoming, yet, frequent additive color filter, this is tending towards reducing spatial resolution and contrast.
Electric paper display is reflection-type but not transmission-type normally.Therefore, they can environment for use light, and in equipment, do not need light source.This allows EPD to keep image and does not use power.Sometimes claim that they are " bistable ", this is because can continue to show black or white pixel, and power only need change from a kind of state to another state.Yet some equipment are stable under a plurality of states, and, thereby support multi-grey level and do not have power consumption.
Though electric paper display has many benefits,, problem is: when with traditional CRT or LCD display relatively the time, the update image for a long time that most of EPD Technology Need is relative.Typical LCD adopts about 5 milliseconds to change to right value, thereby supports the frame rate (usually, the ability by all pixels in the display drive electronics change display limits attainable frame rate) until 200 frame per seconds.On the contrary, for example the magnitude of many electric paper display cost 300-1000 milliseconds of electric ink (E Ink) display changes to black with pixel value from white.Though this update time is usually for being enough by the required conversion of page of e-book,, it is problematic for the interactive application like pen tracking, user interface and video displaying.
(microencapsulated electrophoretic, MEP) a kind of EPD of display moves up to a hundred particles (particle) to upgrade single pixel in viscous fluid (viscous fluid) to be known as the microcapsules electrophoresis.When not applying electric field, the motion of viscous fluid restriction particle, and viscous fluid is given EPD can keep image and the characteristic of non-required power.When applying electric field, this fluid also limits the example motion, and, make this display in comparison upgrade very slow in the display of other type.
When display video or animation, in the duration of frame of video (that is, till receiving next reflectivity of being asked), ideally, each pixel should be in the reflectivity of expectation.Yet each display demonstrates to the request of specific reflectivity and reach some stand-by period between moment of this reflectivity.If video is 10 milliseconds with operation of per second 10 frames and change required time of pixel, then pixel will use 90 milliseconds to show correct reflectivity, and effect will be as desired.If used 100 milliseconds to change pixel, then lucky when pixel reaches the correct reflectivity of previous frame, arrive the moment that changes pixel to another reflectivity.At last, used 200 milliseconds if pixel changes, then except outside the situation of the very approaching correct reflectivity (that is, slowly changing image) of pixel, pixel will no longer have correct reflectivity.
In some electric paper displays, through on display or below interpolation input pickup layer, note is possible.The electric paper display of these types is worked as board.Use pen or contact pilotage to come the lip-deep pixel of writing of active electron paper display, thereby on a piece of paper, write or explain action as pen or pencil.Yet because finite speed that can update image, EPD be not very effective showing aspect the real-time pen tracking.The key request of pen tracking is renewal speed and contrast, their conflicts each other on electric paper display usually.For example, it is shorter than generating the black line time spent on some EPD, to generate light grey line.
Therefore, high expectations is: on current electric paper display, realize high-speed and high-contrast, thereby allow real-time pen tracking.
Summary of the invention
The present invention overcomes the not enough and restriction of prior art through being provided for quick pen tracking and the system and method for low latency display updates on the electric paper display.

System survey
Fig. 2 illustrates the block diagram according to the control system 200 of the electric paper display 100 of some embodiment.Said system comprises electric paper display 100, input pickup panel 212, pen tracking driver 204, display controller 208 and waveform module 210.In certain embodiments, display 100 comprises input pickup panel 212.In certain embodiments, input pickup panel 212 is the touch panel sensors that are deployed in the top of display 100.In other embodiments, input pickup panel 212 is deployed under the display 100, the same as Wacom EMR sensor.
For illustrated purpose, Fig. 2 shows the pen tracking driver 204 and display controller 208 as separation module.Yet, in various embodiments, can merge in pen tracking driver 204 and the display controller 208 any one or all.This allows individual module to carry out the one or more function in the above-mentioned module.
When pen or contact pilotage contacted with input pickup panel 212, pen tracking driver 204 received pen tracking data 202.Pen tracking driver 204 is followed the tracks of active pixel, and keeps frame counter to each pixel.Functional more information about pen tracking driver 204 is provided in the description of Fig. 3-5 below.
Active pixel impact damper (not shown in this figure) reception information, and storage control information.The active pixel impact damper comprises the pixel data that is directly used by display controller 208.More details about the active pixel impact damper are provided below.
The waveform that waveform module 210 storages will be used during the pen tracking on the electric paper display.In certain embodiments, each waveform comprises 256 frames, and wherein, each frame adopts 20 milliseconds of (ms) timeslices, and for all frames, voltage amplitude is a constant.Voltage amplitude be 15 volts (V), 0V or-15V.In certain embodiments, for specific display controller, 256 frames are maximum quantities of the frame in the active pixel impact damper 304 (Fig. 3) that can be stored in.In certain embodiments, use the frame of maximum quantity to make the possible expense of the time slot between the display command during the long stroke pen tracking, repeated call minimum.
During display update, three waveforms are carried out index (index) as follows by controller.In certain embodiments, each pixel has 8 bits; 4 bits are the pixel value of current state, and 4 other bits are the pixel value of next state.In certain embodiments, only two values are used to each state of each pixel: the 0x0 of sexadecimal mode and 0xF, it represents black state and white states respectively.Provide below the sexadecimal mode current and next pixel status value the waveform index to and the tabulation of the state-transition of corresponding pulse (impulse) voltage and representative:
● current=0x0, the next one=0xF, 15V, black is to white;
● current=0xF, the next one=0x0 ,-15V, white is to black;
● current=0x0, the next one=0x0,0V, pixel color is constant; And
● current=0xF, the next one=0xF, 0V, pixel color is constant.
When activating white pixel through pen tracking, its next state in the frame buffer becomes black.Therefore, on pixel, apply-waveform of 15V.On the other hand, if do not activate pixel, so, on this pixel, apply 0V.Confirm duration of voltage-addressed the description to it to be provided below through the frame counter that is used for that pixel.
Fig. 3 illustrates the software architecture according to the pen tracking driver 204 in the control system 200 of some embodiment.Software architecture comprises main routine 302, active pixel impact damper 304, three 306,308 and 310 and two data impact dampers 312 and 314 of module.
Three modules comprise input pickup module 306, setting-out module 308 and frame counter module 310.These modules are three threads of executed in parallel.Said thread utilizes two main data buffers: sampling tabulation 312 and display list 314.Sampling tabulation 312 storages are by the input pickup sampling and screen touch point that do not handled by setting-out module 308 as yet.Display list 314 is followed the tracks of and is upgraded the active pixel of (making its blackening) by display controller 208.Display list 314 is also kept the frame counter that is used for each pixel, and it confirms the duration for the voltage-addressed of each pixel.
Setting-out module 308 reads pen tracking data 202 from sampling tabulation 312.Setting-out module 308 uses pen tracking data 202 between adjacent sampled point, to generate straight line or curve.In certain embodiments, use the line algorithm of Bresenham to come setting-out between per two neighbouring sample points.Technician in the field of Computer Graphics understands the algorithm that is used for setting-out between 2 o'clock well, and, said algorithm will be described no longer in more detail here.
During the setting-out process, in active pixel impact damper 304, upgrade each activated pixels immediately, wherein, for example, write current state value " white (0xF) " and next state value " black (0) ".Setting-out module 308 starts the display update of pixel through this state of pixel is set in active pixel impact damper 304, thereby utilizes desired status information to upgrade the information of pixel.Setting-out module 308 sends which pixel will be updated the information that is associated with.Active pixel impact damper 304 these information of storage, it comprises the information of the directional correlation couplet that should advance with image.In other words, 304 storages of active pixel impact damper are based in part on from the data of setting-out module 308 receptions to upgrade by pixel so that allow in order to help to confirm to activate the information of which pixel.
During setting-out, in active pixel impact damper 304, upgrade the pixel that each is drawn immediately.Simultaneously, setting-out module 308 also is added into display list 314 with each pixel on the line, and uses predetermined number to be provided for the frame counter of said pixel.For example, in certain embodiments, setting-out module 308 also is added into display list 314 with each pixel on the line, and frame counter is set to the value of 15 frames.Subsequently, the sampled data points after handling is removed from sampling tabulation 312.
Fig. 5 illustrates the process flow diagram according to the frame counter module 310 of the pen tracking driver 204 in the Electronic Paper display system of some embodiment.Frame counter module 310 scanning (502) display lists 314, and inspection is used for the frame counter of each pixel of display list 314.Confirm whether (504) scanning has arrived the end of display list 314.If arrived the end (504-is) of display list 314, then frame counter module 310 is waited for preset time at interval, and continues scanning (502) display list 314.In certain embodiments, frame counter module 310 is waited for 20ms, till it continues scanning display list 314.This allows display update after reducing frame counter, to carry out portion of time.
If also whether the end of no show display list 314 (504-is not) then equals zero about frame counter and makes definite (506).If frame counter is not equal to zero (506-is not), then frame counter is subtracted 1 (512).If frame counter equals zero, this means that then this pixel accomplished it from a state to the transformation of next state.Subsequently, index is added 1 (510), and frame counter module 310 continues to confirm (504), and whether it has arrived the end of display list.
If frame counter equals zero (506-is), the pixel value in (514) the active pixel impact damper 304 that then resets, this is because pixel has been accomplished its transformation from a state to next state (for example, from white to black).As an example, current pixel value 0 and next pixel value 0 are write to active pixel impact damper 304.Apply voltage 0 to pixel and upgrade, till the next one changes generation.Remove (516) by the pixel of deactivation from display list 314.
In certain embodiments, depend on application demand (usually, contrast and renewal speed), can select the predefined time interval and frame counter initial value, with the state of the expectation of realization pen tracking pixel.In the given time interval, the frame counter initial value is big more, and the duration of then upgrading is just long more.Yet when the frame counter initial value was enough big, the pixel of renewal finished as saturated black.If saturated is not desired, then should be set to less by the frame counter initial value.
Refer back to Fig. 3, main routine 302 is repeatedly checked display list 314, and, if display list 314 is not empty, then send display command to display controller 208.Fig. 4 illustrates the process flow diagram according to the main routine 302 of the pen tracking driver 204 in the Electronic Paper display system of some embodiment.Main routine 302 is repeatedly checked display list 314, and, if display list 314 is not empty, then send display command to display controller 208.
The main routine 302 of initialization (402), and main routine 302 confirms whether (404) display list 314 is empty.If display list 314 is empty (404-is), then main routine 302 continues inspection (315) display list 314.If display list 314 is not empty (404-is not), then send (406) display command to display controller 208.In other words, because main routine 302 constantly provides this information to display controller 208 when receiving information, main routine 302 keeps display controller 208 activities.
Fig. 6 shows the pen tracking diagram regularly according to the electric paper display 100 of some embodiment.In certain embodiments, each waveform comprises 256 frames, and, take place for the display update 602 of said 256 voltage frames renewal rate with 20ms.Carry out input pickup sampling 604 with the sampling rate of 20ms.Setting-out and active pixel impact damper more NAB also take place with the renewal rate of 20ms.In other words, shown in line pixel display update 608, initial pixel L1 renewal when starting, and line pixel L2 renewal took place in 20ms after online pixel L1 upgraded and starts.Subsequently, line pixel L3 renewal took place in 20ms after online pixel L2 upgraded and starts, or the like.This upgrades the quick pen tracking that allows on the electric paper display by pixel.Can with upgrade whole display irrespectively, upgrade pixel individually with very high speed.
In optional embodiment, can use the pixel in the future that motion prediction confirms to upgrade, upgrade both so that realize high-contrast and pen tracking fast.Can activate each of these pixels in the future, be used for early than being upgraded some frames by the time that style of writing bumps when said pixel reality.After a while,, then immediately turn-off pixel and upgrade if in fact activated pixels is not bumped by style of writing, or with its deactivation.The reflectivity that this thought is based on some electric paper displays has the fact of height nonlinear characteristic time response.
The non-linear indication of reflectivity-time response: when gray states was saturated on arbitrary direction of black or white, display brightness diminished.This hint: after the specific time cycle, human eye can not notice that begin the morning of upgrading.Therefore, for whole state-transition, can use motion prediction to save some times.Non-linear more near the saturation region, just can save more time through using motion prediction.
Can during the setting-out process, carry out motion prediction.Line algorithm prediction is for the moving direction of several steps down, and the pixel in the zone of the given shape on the moving direction of predicting for being arranged in and activate display update.Depend on concrete application, prediction can be based on line or curvature.
Fig. 7 illustrates the diagram according to the method that is used for motion prediction of some embodiment.As shown in Figure 7, line 702 line that is illustrated on the electric paper display to be generated.In Fig. 7, line 702 is in the current point 704 that input pickup is being touched display.When pen tracking when in the future point 706 moves, the pixel in predetermined periods in the active region 708.For example, in certain embodiments, the pixel in the zone 708 is activated 60ms.If preset time in fact un-activation pixel after the cycle (in fact not touched), then with said pixel deactivation or shutoff by the pen tracking motion.The speed of this generation allows the performance of the quick pen tracking when on electric paper display, carrying out pen tracking.The pixel deactivation is meaned:, make it restore to virgin state through using opposite voltage in its identical time quantum of original at that time driving and anti-phase drives it when activating.
When reading this when open, those skilled in the art will still understand: through principle disclosed herein, design with system and 26S Proteasome Structure and Function process, other optional that low latency upgrades for the pen tracking that is used on the electric paper display.Therefore,, should be understood that the disclosed embodiments are not limited to accurate structure disclosed herein and assembly though illustrated and described certain embodiments and application.Here the layout of the methods and apparatus disclosed, operation and details aspect can be made the conspicuous various modifications of those skilled in the art, variation and modification, and do not deviate from spirit and the scope that defines in the accompanying claims.
