Embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, exemplary embodiment cited below particularly, and cooperation accompanying drawing are described in detail below.
Often there is the situation of wrong report point in the liquid crystal indicator of existing integrated touch function when touch control detection.Concrete reason please refer to Fig. 1, and is described below:
As shown in Figure 1, larger change (changing 25V within common 1 μ s) occurs in the rising edge of the scanning gate signal of liquid crystal panel (signal of Gate shown in figure) and negative edge voltage difference within the very short time, impact due to capacitive coupling and panel charging and discharging capabilities, the variation of current potential can cause the change (the particularly current potential of public electrode (Common)) of other current potentials of panel, and causes thus a series of noise (Noise) to disturb.Because touch control detection (touch for capacitance touch screen CTP herein detects) is to judge that by potential difference (PD) the modes such as electric charge discharges and recharges realize, so the wrong report point that the disturbance meeting of public electrode level causes touch-control to survey.
The present invention considers the existence of above problem, for fear of the impact for touch control detection scanning of scanning gate signal rising edge and negative edge, has adopted the scanning detection mode of a kind of minute sequential to solve above technical matters.Specifically please refer to following examples.Need to prove, in following examples, touch control detection scanning all scans as example take the detection of capacitance touch screen (CTP), but the present invention is not limited to this, and the scanning of other touch-screens detects all can use scanning detection method of the present invention.
Embodiment one:
Please refer to Fig. 2, the scanning detection method of a kind of liquid crystal indicator that it provides for the embodiment of the present invention one.Touch control detection scanning (CTP detected) is carried out in its grid scannings (gate scan) at each frame afterwards, namely vacates one section sequential after the grid scanning of each hardwood and carries out touch control detection scanning.
Specifically describe the implementation method of the method in liquid crystal indicator below in conjunction with Fig. 3 and Fig. 4.
Need to prove, for the design requirement of narrow frame, it is important selection that integrated grid drive amorphous silicon circuit (ASG).Usually the ASG circuit is all to utilize rising edge, the negative edge of clock signal C K, counter-rotating clock signal C KB, the level signals such as start trigger signal STV, upper level grid output signal Gaten to modulate high level voltage VGH, low level voltage VGL to make output grid sweep waveform at the corresponding levels.Wherein, STV is the start trigger signal, and it has determined the work of the ASG circuit of the first order, and then hands on by circuit one-level one-level.Because the amorphous silicon electron mobility is lower, therefore need the thin film transistor (TFT) (TFT) of very large breadth length ratio to make the afterbody output circuit, proportion is maximum in the panel area that the ASG circuit takies.
At first, as shown in Figure 3, it is a kind of structural representation of liquid crystal indicator.As shown in the figure, this liquid crystal indicator comprises that multistage grid drive amorphous silicon circuit (ASG) 100, display unit 200 and touch control unit 300.Wherein, multistage grid drive amorphous silicon circuit cascade successively, respond a clock signal CK or counter-rotating clock signal C KB, activate successively its corresponding gate line, wherein first order grid drive amorphous silicon circuit and work under the driving of start trigger signal STV, and other grades grid drive amorphous silicon circuit and work under the upper level grid drive the driving of output signal of amorphous silicon circuit successively; Touch control unit 300 couples start trigger signal STV and the afterbody grid drive amorphous silicon circuit, and with the trigger pip of start trigger signal STV as the touch control detection end of scan, drive the final grid output signal of amorphous silicon circuit as the trigger pip of touch control detection scanning beginning with the afterbody grid.
In addition, display unit 200 often comprises many gate lines, data line and a plurality of pixel, each pixel is made of thin film transistor (TFT) and liquid crystal capacitor, and data drive circuit exports data-signal to data line, and the ASG circuit exports gate drive signal to gate line.Due to this technology that is well known to those skilled in the art, therefore in this not narration in detail.
Below in conjunction with Fig. 4, describe the principle of work of above liquid crystal indicator in detail.When integrated circuit (IC) output start trigger signal STV, touch control unit 300 receives the STV signal, and this STV signal stops the scanning for touch-control when effective, and the ASG circuit is started working, export step by step scanning gate signal, to the last one-level output gate signal is (for example, being high level) effectively.Touch control procedures that this afterbody grid output signal triggers in touch control unit 300 begin to scan, until next hardwood when beginning IC output STV signal effective, and so forth.Thus, just realized the function of minute sequential grid scanning and touch control detection scanning.
Better, the final grid output signal of afterbody ASG circuit is the scanning gate signal of vitual stage (Dummy).This is because the scanning gate signal of Dummy level is not input in liquid crystal panel, so there is not the situation of overlap capacitance coupling level, its rising edge, negative edge can not impact touch control detection scanning yet.Simultaneously, ASG circuit as the Dummy level is inputted owing to not needing to make, only need afterbody ASG circuit design is got final product for output Dummy sweep signal, therefore do not need the TFT circuit of very large breadth length ratio, therefore the ASG as the Dummy level can save a lot of panel areas, can not cause harmful effect to border width.
Embodiment two:
Please refer to Fig. 5, the scanning detection method of a kind of liquid crystal indicator that it provides for the embodiment of the present invention two.It inserts touch control detection scanning (CTP detected) at least one times among the grid scannings (gate scan) of each frame.Usually inserted mode is: after every several rows grid scanning, insert touch control detection scanning, until complete this frame grid scanning.At this, the number of times that inserts touch-control scanning is not limited, those skilled in the art can set as required.Yet through experiment and analysis, better, when the sweep length of several rows grid scanning reaches 5mm, insert touch control detection scanning.For example, corresponding touch-control spacing about the corresponding 30 row grid scannings of general 5mm, is inserted touch-control scanning, carries out grid scanning after completing, and so forth until complete scanning and the detection of whole screen again.Simultaneously, through the inventor repetition test, when finding that sweep length in the scanning of several rows grid is between 3mm-6mm, insert touch control detection scanning and all can realize good touch control detection effect.
Specifically describe the implementation method of the method in liquid crystal indicator below in conjunction with Fig. 3, Fig. 6.
This liquid crystal indicator comprises multistage ASG circuit 100, display unit (not shown) and touch control unit 400.Wherein, the cascade successively of multistage ASG circuit, respond a clock signal CK or counter-rotating clock signal C KB, activate successively its corresponding gate line, wherein first order grid drive amorphous silicon circuit and work under the driving of start trigger signal STV, and other grades grid drive amorphous silicon circuit and work under the upper level grid drive the driving of output signal of amorphous silicon circuit successively.Itself and embodiment one difference are setting and the principle of work of touch control unit 400.As Fig. 6, this touch control unit 400 inserts touch control detection scanning at least one times among the grid scanning of each frame, it is couple to one-level grid corresponding to insertion position and drives amorphous silicon circuit, and drive the initial grid output signal of amorphous silicon circuit with this grade grid as the trigger pip of touch control detection scanning beginning, and when needs finish touch control detection scanning, drive the grid output signal of amorphous silicon circuit as the trigger pip of the touch control detection end of scan with the grid of respective stages.Usually, the corresponding 3-5 level grid of touch control detection scanning drive amorphous silicon circuit.As seen, the present embodiment utilizes the grid output signal of respective stages to realize with the trigger pip that finishes touch-control scanning the purpose that the grid driven sweep separates with the touch-control scanning sequence as the scanning of beginning touch-control.
better, utilize equally the Dummy level scanning gate signal of ASG circuit to realize above function, namely when needs insert touch control detection, this grade ASG circuit design is output Dummy scanning trigger pip, with the trigger pip as touch control detection scanning, in the process of touch control detection, corresponding some grades of ASG circuit are exported several Dummy signals, when needs finish touch control detection, this grade ASG circuit design is output Dummy end of scan signal, to finish touch control detection scanning, and begin grid scanning at next stage ASG circuit, the Dummy of design output herein signal, the advantage of Dummy scanning trigger pip and Dummy end of scan signal is with embodiment one, do not repeat them here.
As can be seen from the figure, touch control unit couples grid every some grades of grid driving amorphous silicon circuit and drives amorphous silicon circuit, and drives the grid output signal trigger pip that scanning begins and finishes as touch control detection of the respective stages of amorphous silicon circuit with its these grid.Better, touch control unit couples a grid driving amorphous silicon circuit every the grid sweep length of 5mm, and preferably, touch control unit is coupled to grid driving amorphous silicon circuit every the grid sweep length of 3mm-6mm.
Embodiment one vacates one section sequential and carries out touch control detection scanning after the grid scanning of each hardwood.This mode is simple easily realizes especially the ASG circuit design not being had extra requirement, can realize reducing costs, and improve the purpose of product yield.Embodiment two inserts touch control detection scanning after the scanning of several rows grid, carry out grid scanning after completing, and so forth until complete scanning and the detection of whole screen again.The method can greatly improve panel touch-control response speed and resolution.
Need to prove, the invention provides two kinds of sequential separation schemes, also can carry out combination for two schemes and design.Simultaneously, this design also can be used in the separation of plug-in capacitor screen sequential, is used in outer hanging panel and is driven situation about having a strong impact on by grid.
In sum, the embodiment of the present invention provides in conjunction with CTP, the ASG fabrication techniques is high-quality has the liquid crystal panel of touch controllable function and drives integration technology.Avoiding liquid crystal panel and contact panel owing to being produced on the particularly noise that is coupled out of grid scanning rising edge, negative edge of mutual interference mutually that in liquid crystal cell, large stray capacitance causes, utilize the existing signal of ASG circuit, under the prerequisite that does not increase the hardware block, the differentiation on the sequential has been carried out in scanning, avoided mutual interference.Design mainly for sequential circuit logic and system combination, optimized Effect on Detecting.
