Fig. 7 is applicable to when display element of the present utility model is LCD that light source is positioned at the structure in general displayed map of TFT substrate side surfaces.Fig. 8 is that light source is positioned at the promptly straight structure in general displayed map of mode down of TFT substrate rear side, and Fig. 9 is that light source is positioned at the structure in general displayed map of TFT substrate bottom surface with optical sensor.

In addition, Figure 10 is the overview expansion plane displayed map according to optical sensor of the present utility model, Figure 11 is that the state profile of light source enlarges the plane displayed map on the face identical with optical sensor among Figure 10, Figure 12 is applicable to Figure 10 to Figure 11, it is the state profile decomposition profile diagram of each comfortable glass bottom surface of light source and optical sensor, Figure 13 is the state profile decomposition profile diagram of each comfortable TFT substrate bottom surface of light source and optical sensor applicable to Figure 10 to Figure 11.

And, Figure 14 is, in the utility model in order to differentiate the validity of induction, set separately from effective territory of the light of light source irradiation with from the effective range of the light of backlight assembly light source irradiation, so that distinguish perform region separately, be to summarize the process flow diagram that shows the perform region of the frame in the frequency field.Figure 15 is that the overview that is presented at the optical sensor of panel pixel identical faces enlarges planimetric map.

Figure 16 is after affiliated pixel activates startup successively in addition, forward the state profile displayed map that initial pixel refreshes to from last pixel, Figure 17 person of being to use is close to display panel side with human body or things and when being touched, the moment of refreshing, panel is in the situation displayed map of one of them pixel in each pixel, in display device panel, be in any one position even mean user's human body or things, always have the more than one expansion displayed map that refreshes pixel in its field.

And, the effective value of Figure 18 light that to be decision returned by human body or things and set the displayed map of threshold values input value, Figure 19 is a light source with characteristic frequency when being identified as effective value, as the wrong minimizing scheme that peripheral light source is caused, light source is carried out the method displayed map of encode.

As shown in the figure, the utility model carries out the printing opacity matrix possessing optical sensor 113 on the numerous point of crossing between matrix pattern 112 grid of patterned process with lattice shape on TFT substrate 100 bottom surfaces that constitute TFT-LCD panel 100 or glass 111 surfaces that possess above it.

So optical sensor 113 is to form with the translucent body or the transparent body, and does not hinder the image quality of the portrait that shows by TFT-LCD panel 100.

So, the optical sensor 113 that is possessed be from the identification of the light of light source 300 transmissions described later near a certain position of the things of TFT-LCD panel 100 state of the light of secondary reflection again, apply its signal value to induction test section 120 sides.

In addition, light source 300 has the light of certain frequency with irradiation so that make its transmissive TFT-LCD panel 100.

Show as Fig. 7, so light source 300 is formed on the side surface part of the TFT substrate 110 that constitutes the TFT-LCD panel, after reflecting plate 101 reflections that are configured in its underpart, shine or light source 300 be configured in the straight below of above-mentioned TFT substrate 110 to above-mentioned TFT substrate 110 sides, according to straight radiation modality down, make light see through above-mentioned TFT-LCD panel 100.

So light source 300 is TFT substrate 110 or glass 111 surfaces that semiconductors such as light emitting diode or transistor are formed on TFT-LCD panel 100 by processes such as semiconducter engineerings, be used in the wave band of the light source 300 of light output, the wave band of all spectra can be used, and the infrared ray beyond the general near infrared ray frequency can certainly be used.

So light source or optical sensor are in the pixel forming process in the TFT-LCD panel manufacturing process, and the step through same can be formed on the same face.

At this, the configuration structure of light source 300 is different with said structure, show as Fig. 9, in side with each optical sensor 113 of a plurality of quantity alignment arrangements, each self-configuring light source 300, the light that makes light source 300 irradiation is by behind the TFT substrate 110 transmission TFT-LCD panels 100, may be positioned at the things in the place ahead or human body secondary reflection again, by the optical sensor 113 side joints receipts of above-mentioned light source 300 sides configuration.

In addition, show, make light source 300 and optical sensor 113 respectively form 1 group, can constitute the bottom surface of doing pattern processing or TFT pole plate 110 in the bottom surface of glass 111 and do the pattern processing as Fig. 9 and Figure 11.

The Ref. No. L of Figure 10 to Figure 11 is meant connecting line, and F is meant the socket head that respectively connects each connecting line.

Because the configuration structure of above-mentioned light source 300, light sees through TVT-LCD panel 100 after light source 300 irradiations, by in-plant human body or things secondary reflection again, light such as Fig. 7 to Fig. 9 of returning.

For example, from the light of light source 300 irradiation after human body or things reflect once more, guide TFT pole plate 110 sides into, at it again in the light of secondary reflection, as shown in the figure, near things, that is, claimed " a ", in the remote various things that exist by the light of the finger of human body reflection, promptly from each TFT-LCD panel (100) gradually away from the position again the light of secondary reflection claim " b ", " c ".

As shown in the figure, TFT-LCD panel 100 is again in the light of secondary reflection, as above-mentioned situation, reflection position once more separately, that is, the intensity of the light " a " that returns of secondary reflection and the amount light " b " that compares again from human body (finger on the figure) position of TFT-LCD panel 100 closest approaches, " c " is big, therefore in the effective sunlight detection-phase described later, only above-mentioned light " a " is identified as effective sunlight.

So, the light of the light source that embodies in each example 300 irradiations is for implementation procedure and is presented at the front face side of TFT-LCD panel 100, human body or the pen etc. near the time, through human body or things reflection, as mentioned above, receive the light that reflexes to belonging positions once more with countless optical sensor 113, in its data, as above-mentioned example, after induction test section 120 is identified as light " a " effective light and detects, follow the trail of the position coordinates of its effective light.，

So, load the effective procedure on the position coordinates that above-mentioned induction test section 120 followed the trail of, information shows by TFT-LCD panel 100 under making.

In addition, owing to be equipped with the light source that backlight assembly possessed of 100 configurations on the TFT-LCD panel and the light source 300 that embodies according to the present invention simultaneously, therefore the light from two light source irradiation needs to distinguish, thereby, the light source that backlight assembly is possessed has the visible rays field, and shows on picture by TFT-LCD panel 100 and colorized optical filtering.The light source 300 that is suitable in the utility model is the touch test light source, and can embody its touch function.The light source of above-mentioned backlight assembly will be with different frequency field band irradiations with touch test light source 300, so that get rid of the mutual interference of touch function and picture demonstration referential function, what embody more correct action is feature.

In addition, the light source of the visible rays that shows for picture, that is, the fluorescent lifetime the when touch of backlight group of light source luminescent time and picture is started otherwise same is done usefulness so that get rid of the mutual interference of each light source, the action correctness on raising TFT-LCD panel 100 pictures.

For example, shown in Figure 14, when the frequency of the frame of TFT-LCD face 100 pictures is per second 60Hz, 1 or do not influence the action the field whether light source 300 of touch sensible is arranged as the affirmation in the utility model with a plurality of frames in the scope that picture constitutes therein, in its scope, as in the purposes of the various information of screen displayed, the light source with backlight assembly visible rays field is closed, and the unlatching light source irradiation is approaching and touch TFT-LCD panel 100 things, so that induction.

Thereupon, as Figure 14, (V-Sync) is decided to be 60Hz vertical synchronization, and the entire frame benchmark of picture per second is 60 o'clock, and the action of light source 300 is: its 59 frame is that the backlight assembly light source shines, and makes light source 300 irradiations in the interval of 1 frame of residue.The light source of backlight assembly is just opened in 59 frames in the above-mentioned explanation, remains when closing in 1 frame, and the light source 300 of touch sensitive is opened in the interval of its 1 frame.Be to carry out the On/Off action,, be not subjected to the limitation of this language so it uses the term of selecting for use for explanation the utility model with small time difference.

For example, the backlight assembly light source is always to keep opening, and as Figure 13, by the driving time schedule controller chip of each pixel and TFT-LCD panel 100, successively to outside show image information.This difference only is atomic little time difference, therefore is identified as simultaneously by the user to show.

Just, after opening in 59 frame intervals, as shown in figure 12, the moment that flushes to initial pixel is to belong to residue 1 frame (1/60 second).

By 1 frame of this moment, in optical sensor, discern from the light of the touch discerned of light source 300 irradiations, and be judged to effective light.

That is, Figure 16 is, panel enlarges to the utmost when refreshing and shows each pixel just like the figure of Kai Qiing successively.For example, user's part health is near TFT-LCD panel 100 and when touching, always there is refresh point in each pixel on the figure under the touch point 400, the light of the light source 300 by the irradiation of its refresh point, when the user also will touch near TFT-LCD panel side, by part health secondary reflection again, and be identified as effective light by optical sensor 113.

Thereupon, even the user is near any point of TFT-LCD panel 100, and formation touch point 400, because there is numerous pixel in this point, exist in the pixel simultaneously and refresh the pixel of moment, therefore its moment light source 300 light by user's health (for example finger) again secondary reflection turn back to optical sensor 300, discerning its signal is effective light.

Therefore, control program is opened the light source of backlight assembly during affiliated frame (59 frames), the light of radiation source 300 on the residue frame, or during the pixel show image information that forms by R, G, B, after show image information during the affiliated frame (59 frame), the light source 300 of moment transmission when refreshing the once more light intensity and the light quantity of secondary reflection again can become big relatively, therefore is identified as effective light, and can carries out touch sensible.

Mode so, the light source that light source and the utility model embodied 300 of backlight assembly are when moving separately one or more image durations, and as shown in figure 15, each pixel of TFT-LCD panel 100 starts successively from first pixel of upper end, right side, to constitute a frame.

Thereupon, behind the panel refresh, one pixel is when starting state, the most optical sensors 113 that are formed on periphery are from the light of light source 300 irradiations, can monitor part objects such as the health that whether detects near TFT-LCD panel 100 and effective light of secondary reflection again, therefore can grasp correct sensed position, can repel the peripheral interference of light of irradiations such as sunshine or indoor illumination, and part touches beyond the pixel of the starting state that is progressively refreshed, during error-detecting such as induction input, also can bring into play remarkable effect.

This can bring into play its excellent performance in single touch sensible.

In addition,, can set, near the human body of TFT-LCD panel and other display panels or things and the threshold values input value of sensed optical sensor according to user or program as Figure 18.This point is to mean the touch distance that can regulate TFT-LCD panel and other display panels arbitrarily

So, as Figure 18, with each self-induced light " a ", " b ", the influence value of " c " set threshold values input value Vi, can set for and only discern effective value " a " in Fig. 7 to Fig. 9.

In addition, as Figure 19, be positioned at or be formed on that TFT-LCD panel and other display panels shine, have and load certain code in the light source of appropriate frequency and shine, distinguish mutually with sunshine with similar frequency or room light, thus the induction mistake of fundamentally distinguishing and preventing to take place.

In addition, as Figure 20, form in the panel of optical sensor with matrix on whole TFT-LCD panel and other display surfaces, as A, can be identified on position 1 and the position 2 the induction input that touches simultaneously simultaneously, this type of multiplex induction input with each independently optical sensor can carry out fully, and as B, can be arbitrary shape (palm) object identification similar shape,, then can only discern certain field if only form optical sensor in the field of phone shape.Therefore be not only the induction (iconifying) of area, and can be used in the purposes of getting rid of unnecessary touch field.

And, when waiting touch with finger, after the fingerprint ridge that the light source of irradiation is pointed is reflected as C, according to light intensity and the light quantity of returning the optical sensor that forms with matrix, will identical or similar influence value connect each other each in program, obtain the fingerprint image, therefore can be used in the fingerprint recognition induction.

In addition,, appended aiding sensors, so that improve and use its function in order to discern the moment that directly touches in TFT-LCD panel and other display panels.Can adopt a kind of in all possible sensors such as resistance mode sensor, capacitive way sensor, piezoelectricity mode sensor, ultrasound sensors, infrared ray sensor, shock sensor, nano-sensor, position-detection sensor, acceleration sensor, peri position sensor, temperature sensor, imageing sensor as aiding sensors.

Utilization has TFT-LCD panel 100 and other display panels of said structure, and the touch sensible method in the display device that utilizes light source is described.

At first, in the LCD type display device of utilizing light source that above-mentioned formation of the present utility model possessed, the side of TFT substrate 110 or directly descend mode, or the light output stage of output in the light source 300 that is equipped with on each optical sensor 113 that is steaming on above-mentioned TFT substrate 110 bottom surfaces or its glass surface that possesses above; Light input phase of sensitization and effective light detection-phase; Through detecting the position data detection-phase of above-mentioned effective optical position; Data and demonstration stage etc. under the output, need through a series of processes.

As mentioned above, above-mentioned smooth output stage is to possess in the side of TFT substrate 110 or directly, or at above-mentioned TFT substrate 110 or glass 111 back sides that possess above it each side with the countless optical sensor 113 of lattice shape arranged possesses light source 300, with this irradiation light.

So light is the light with appropriate frequency, and will be set in certainly in above-mentioned each optical sensor 113 decipherable frequency field.

Above-mentioned light input phase of sensitization is meant: from the light source irradiation of above-mentioned smooth output stage, after having the rayed of certain frequency, be positioned at the object of TFT-LCD panel 100 front face side, promptly directly touch or do not touch TFT-LCD panel 100, but be close to certain field or closely the time, in order to give the effect that touches above-mentioned TFT-LCD panel 100, to from the light source of above-mentioned light source irradiation by approaching human body or things reflection, and the light that turns back to TFT-LCD panel volume is responded to the stage of processing.

Be to have utilized photoelectric sensor in the utility model so, but also can use the sensor that can substitute with it certainly at the light input optical sensor 113 that phase of sensitization adopted.

In addition, optical sensors such as above-mentioned photoelectric sensor 113 are on TFT substrate 110 or glass 111 surfaces, and through processes such as semiconducter engineerings, even distribution process is so that induction is by the light with appropriate frequency of secondary reflection again such as above-mentioned human body or object.

So, returning light intensity or light quantity may be different, for example by the most near TFT-LCD panel 100, and require the human body of touch sensible action or light intensity and the light quantity that things is reflected, and require to break away from the things of above-mentioned touch action, contiguous or near, the remote multiple things that exists is by the light intensity and the light quantity of secondary reflection can only be different again.

That is, as accompanying drawing 7 to Fig. 9, bigger relative of the light intensity that light intensity that infrared ray " a " shows and light amount ratio infrared ray " b " reach " c " with light quantity.

To Fig. 9, process is responded to the multiple light that together returns thereupon, and is converted to electric signal inequality, to a series of processes such as data processing division 130 reception and registration as accompanying drawing 7.

As mentioned above, above-mentioned effective light detection-phase is meant; The light that returns to TFT-LCD panel 100 is handled in induction, is converted to different electrical signals, handles the signal value to data processing division 130 communications, detects the stage of effective light in signal value.

At this, light by near and be positioned at the human body of TFT-LCD panel front face side or things reflection and return, and the signal value that above-mentioned optical sensor 113 receives is converted to electrical signal to be meant, near the TFT-LCD panel and by the human body of contact or the things light intensity and the light quantity of the light of secondary reflection again, in contrast, with above-mentioned TFT-LCD panel 100 gradually away from and the light intensity of the light of secondary reflection and light quantity again, naturally can be variant.In the utility model, turn back to the light intensity of each field light of TFT-LCD panel and the difference of light quantity, distinguish electrical signal and conversion by the field according to secondary reflection more like this.

So, light intensity and light quantity according to each light that returns, after being transformed into electric signal separately, as mentioned above, the signal value of its conversion after data processing division 130 data communications inputs, processings that perform calculations, tracking (for example: in the signal value of reception has top condition, size with conditioned disjunction signal of mxm.) signal value detects effective light.

Therefore, effectively only " a " of accompanying drawing 7 to Fig. 9

Above-mentioned stage position detection is meant, the detection-phase of effective light (that is the light on the drawing " a ") receiving position that detects according to above-mentioned effective light detection-phase.

Through the detection-phase of above-mentioned effective light detect be identified as effective range light after, the signal of its detection is in data processing division 130 comparative analysiss, the induction interface of the optical sensor 113 that constitutes with equally distributed photoelectric sensor calculates accurate coordinate position.
