For making purpose of the present invention, structure, feature and function thereof there are further understanding, cooperate embodiment to be described in detail as follows now.
See also Fig. 1 to Fig. 3, Fig. 1 is the synoptic diagram of optical touch screen 1 according to a preferred embodiment of the present invention, and Fig. 2 is the functional block diagram of optical touch screen 1, and Fig. 3 is the primary structure sectional view of optical touch screen 1.Optical touch screen 1 mainly comprises touch-control and shows module 12, handles module 14, input media 16 and module backlight 18, and other comprises housing 20 with ccontaining aforementioned components.Handle module 14 and show that with touch-control module 12, input media 16 and module backlight 18 are electrically connected respectively.Optical touch screen 1 utilizes touch-control to show that module 12 can produce the corresponding simulating signal based on the intensity that receives light, and then produces digitized video, to realize scan function.It describes in detail as hereinafter.
Touch-control shows that module 12 comprises transparency carrier 122, a plurality of pixel display unit 124 and a plurality of light sensing unit 126, pixel display unit 124 all is arranged under the transparency carrier 122 with light sensing unit 126, and light sensing unit 126 is between pixel display unit 124.In present embodiment, light sensing unit 126 is evenly to distribute, in Fig. 1, with the distribution scenario of the exaggerative remarked pixel display unit 124 of grid of dashed lines with light sensing unit 126 (representing with hachure); But the present invention is not exceeded with this kind distribution.Each light sensing unit 126 can be received from the light injected transparency carrier 122 tops to produce the simulating signal to the intensity of the light that should receive.
Furthermore, in present embodiment, pixel display unit 124 is to be integrated in the same optical element structure with light sensing unit 126.As shown in Figure 3, be formed with optical filter 1242,1262, pixel electrode 1244 and liquid crystal alignment layer 1246 on transparency carrier 122, touch-control shows that module 12 still comprises another transparency carrier 128, is formed with pixel electrode 1248 and liquid crystal alignment layer 1250 on it.These two transparency carriers, 122,128 butt joints, filling liquid crystal is to form liquid crystal layer 1252 therebetween; And corresponding optical filter 1262 forms OPTICAL SENSORS 1264 simultaneously with pixel electrode 1244, for example the CMOS sensor; But the present invention is not as limit.Wherein, transparency carrier 122,128 is in order to carrying, fixing and other members of protection; Optical filter 1242, pixel electrode 1244, liquid crystal alignment layer 1246, liquid crystal layer 1252, liquid crystal alignment layer 1250 and the aforementioned a plurality of pixel display unit 124 of pixel electrode 1248 corresponding compositions; Optical filter 1262 and the aforementioned a plurality of light sensing units 126 of OPTICAL SENSORS 1264 corresponding compositions.Module 18 backlight is arranged at touch-control and shows under the transparency carrier 128 of module 12, in order to provide backlight optionally to pass pixel display unit 124 and transparency carrier 122.
What remark additionally is, in present embodiment, be to be disposed in the structure of pixel display unit 124 on light sensing unit 126 entity structures, so can reduce the viewing area area of this pixel display unit 124, but this area reduction can compensate by the configuration that only enlarges this pixel display unit 124.In practical application, for ease of making, optical filter 1242,1262 is that entity is same; In other words, the optical filter 1242 adjacent to the pixel display unit 124 of light sensing unit 126 is formed by same optical filter with optical filter 1262.But the present invention is not as limit, for example when light sensing unit 126 area occupied are identical with pixel display unit 124 areas occupied, 1262 of the optical filters of light sensing unit 126 need not to use same entity optical filter with the optical filter 1242 of pixel display unit 124, and can form individually; This moment, then aforementioned optical filter 1262 was from omitting if the OPTICAL SENSORS of light sensing unit 126 1264 itself only can be to the coloured light sensing of certain wave band.In addition, in present embodiment, pixel display unit 124 refers to form the display unit of image pixel, and lcd technology is many at present realizes that with RGB three looks present embodiment is also as example, but the present invention is not as limit.Therefore, optical filter 1242 comprises ruddiness optical filter, green glow optical filter and blue filter, that is pixel display unit 124 comprises three kinds of not homochromy pixel display unit.At this moment, the coloured light of 126 sensings of each light sensing unit is not quite similar, thus can be considered the light sensing unit that light sensing unit 126 comprises different color light, and then realize the function of chromoscan; In other words, light sensing unit 126 comprises the light sensing unit of at least one first coloured light and the light sensing unit of at least one second coloured light, this first coloured light is different from this second coloured light, and this first coloured light and this second coloured light system is selected from one of them of the coloured light group that is made up of red light, green light and blue light respectively.Supplementary notes is again, in present embodiment, the size of light sensing unit 126 is significantly less than pixel display unit 124, so the position is set will the influence the contiguous light that passes pixel display unit 124 through reflect into the ratio into light sensing unit 126 from file 2 of light sensing unit 126, only this can being provided with position (for example shown in Figure 4 hereinafter be provided with position) or being improved via compensation operation by adjustment light sensing unit 126.Aforementioned structure can realize based on general liquid crystal touch control screen manufacturing technology, repeat no more.
On using, one file 2 (being illustrated among Fig. 3 with dashed rectangle) is positioned on the transparency carrier 122, utilize light sensing unit 126 to receive the light 22 of files 2 reflections or pass the light 24 (all being shown among Fig. 3) of file 2 with dotted arrow, and then generation is about the digitized video of image on the file 2, as shown in Figure 3.Wherein, the light 22 of file 2 reflections refers to the light from module 18 emissions backlight, pass pixel display unit 124 and, pass transparency carrier 122, optical filter 1262 again for file 2 reflections, and further be that OPTICAL SENSORS 1264 receives; The light 24 that penetrates file 2 refers to that surround lighting passes file 2, passes transparency carrier 122, optical filter 1262 again, further is that OPTICAL SENSORS 1264 receives.Therefore, in present embodiment, light that light sensing unit 126 is received is real to be the light of this filtration, so light sensing unit 126 can carry out sensing at the coloured light composition that optical filter 1262 is leached, and to the simulating signal of the intensity of the light that should receive.The simulating signal that each light sensing unit 126 produces is sent to handles module 14 converting the GTG value to, and then produces the digitized video about image on the file 2.
What remark additionally is, in present embodiment, though light sensing unit 126 is evenly distributed between the pixel display unit 124, but the present invention is not as limit, for example in an embodiment, the light sensing unit of three kinds of coloured light can be assembled setting, can obtain the simulating signal of light component of all kinds at the same area roughly simultaneously, and then obtain more exact figure colors of image, as shown in Figure 4; Wherein among Fig. 4, the English alphabet of pixel display unit 124 marks is in order to indicating its coloured light that can launch, and 126 of light sensing units are represented with the black block of cells.In addition, because of present manufacture of semiconductor technology, light sensing unit 126 still accounts for no small configuration area with respect to pixel display unit 124, so if when not having the display brightness compensatory device to implement, the quantity that light sensing unit 126 is provided with still belongs to limited, therefore when process technique can overcome, do not exceed with embodiment herein in be provided with quantity and the position of light sensing unit of the present invention.
Though aforementioned with touch-control, show the embodiment explanation be integrated in same panel construction, the present invention is not as limit.See also Fig. 5, it is the primary structure sectional view according to the optical touch screen 3 of another preferred embodiment of the present invention.Optical touch screen 3 is that with optical touch screen 1 main difference part the contact panel of optical touch screen 3 is non-to be integrated in same panel construction with display panel.In detail, the touch-control of optical touch screen 3 shows that module 32 comprises three transparency carriers 322,328,330, wherein 322,328 of transparency carriers are formed with optical filter 3242, pixel electrode 3244,3248, liquid crystal alignment layer 3246,3250 and liquid crystal layer 3252, in order to form a display panels, it comprises several pixel display unit 324; Form a plurality of light sensing units 326 on the transparency carrier 330, in order to light 22 that receives file 2 (being illustrated among Fig. 5 with dashed rectangle) reflection or the light 24 (all being shown among Fig. 5 with dotted arrow) that passes file 2, and then generation is about the digitized video of image on the file 2.In other words, transparency carrier 322 is arranged under transparency carrier 330 and the light sensing unit 326 and on pixel display unit 324, this moment, but the black mask 332 of 3242 of optical filters of light sensing unit 326 respective pixel display units 324 was provided with, and this can reduce light sensing unit 326 and hide the area that pixel display unit 324 show.About other explanations of each member in the optical touch screen 3, see also the explanation of the structure of identical name in the optical touch screen 1 in each figure and the preamble, repeat no more.Similarly, optical touch screen 3 also can scan file 2.Supplementary notes is in addition, though optical touch screen 3 is an example with the lcd technology, the present invention is not as limit; For example the present invention also can realize the aforementioned document scan function to attach contact panel on the traditional C RT display.
Because optical touch screen of the present invention itself is the tool Presentation Function, therefore for example in optical touch screen 1, handle module 14 can control pixel display unit 124 with the state that shows this digitized video and respond input media 16 to store or to delete this digitized video.This input media 16 is a button, as shown in Figure 1; But the present invention is not as limit.For example input media 16 is realized with more operating key, or is aided with LCD Panel, or directly realizes input media 16 with a less liquid crystal touch control screen in addition; Again for example, touch-control shows that module 12 had touch-control input function, so can realize the function of aforementioned input media 16, for example shows a block of cells on touch-control shows the screen of module 12, touches affirmation to indicate the user.
Aforementionedly optical touch screen of the present invention is illustrated with embodiment, below will be to file scan method of the present invention explanation.See also Fig. 6, it is the process flow diagram according to a preferred embodiment of file scan method of the present invention.File scan method of the present invention is to use optical touch screen of the present invention to implement, for ease of the flow process of key diagram 6, present embodiment uses aforementioned optics Touch Screen 1, the related elements of quoting in follow-up explanation, see also aforementioned correlative type, do not specialize in the text.This document scan method at first switches to scan pattern with optical touch screen 1, shown in step S100; Then, file to be scanned 2 is positioned on the transparency carrier 122, shown in step S110; It is backlight to drive module 18 emissions backlight, shown in step S120; Open each pixel display unit 124, make and should be backlight to reflect to advance towards transparency carrier 122 again, shown in step S130 by pixel display unit 124 and transparency carrier 122 and by file 2; Drive each light sensing unit 126 and receive the light that passes transparency carrier 122 to produce simulating signal, shown in step S140 to the intensity of the light that should receive.
Supplementary notes be, in step S130, though each pixel display unit 124 is opened, so that backlightly can directly pass liquid crystal layer 1252, to produce white light, this promptly makes pixel display unit 124 original images that show eliminate, the present invention is not as limit.For example, the pixel display unit 124 of adjacent light sensing cell 126 is opened to produce white light in this place, or keep still that image shows and directly with the light of show image source as light sensing unit 126 light sensings, only may examine the color that needs show image light this moment, do the suitable compensation computing.In addition, the light sensing unit 126 of optical touch screen 1 comprises optical filter 1262 and OPTICAL SENSORS 1264, therefore step S140 is implemented by the following step: optical filter 1262 filters the light that passes transparency carrier 122, and drives light that OPTICAL SENSORS 1264 receives these filtrations to produce this simulating signal to the intensity of the light that should receive; But the present invention is not as limit, and the explanation about light sensing unit 126 runnings and distortion thereof sees also aforementioned explanation about optical touch screen of the present invention, repeats no more.
Then, this document scan method drive to be handled module 14 and is received this simulating signal of producing from each light sensing unit 126 to produce the digitized video about image on the file 2, shown in step S150; For example earlier this simulating signal is represented with GTG, and then produced this digitized video, but the present invention is not as limit.For making the user can confirm the scanning situation, this document scan method drives handles module 14 control pixel display unit 124 to show this digitized video, shown in step S160.In like manner, for confirming whether need store this digitized video, the user can confirm by input media 16, at this moment, this document scan method is then utilized and is handled the state that module 14 is responded input media 16, for example pressed state of button, to store or to delete this digitized video, shown in step S170.If the user is dissatisfied when time scanning result, or when desiring overline scanning, the user is from can be by the operation interface of operating optical Touch Screen 1, and for example input media 16, to come into effect scanning operation from step S120, needless to say give unnecessary details.
In previous embodiment, the light source as light sensing unit 126 sensings backlight that this document scan method utilizes module 18 backlight to provide, but the present invention is not as limit.See also Fig. 7, it is the process flow diagram according to another preferred embodiment of file scan method of the present invention.In present embodiment, this document scan method also makes optical touch screen 1 be example.The process flow diagram of Fig. 7 roughly process flow diagram with Fig. 6 is identical, and difference is the light source difference of scanning document 2, and in the process flow diagram of Fig. 7, this document scan method is closed each pixel display unit 124 so that light can't pass through, shown in step S122; And external light source (for example other lighting devices, surround lighting that intensity is enough etc.) is provided, the intensity of this external light source is enough to pass file 2 to produce the light of advancing towards transparency carrier 122, shown in step S132.Therefore, the optical touch screen 1 original image that shows is promptly closed and is made optical touch screen 1 be in the blank screen state, to avoid the sensing of stray light sensing cell 126 backlight.In brief, file scan method of the present invention only needs to produce the light that reflects or penetrate file 2 and advance towards transparency carrier 122 from file 2, promptly can be used as the scanning light source source; But the present invention is not still as limit.
Compared to prior art, the light sensing unit that known optical touch screen uses, only can make binary judges, can't react the GTG of image on the file, and the known scanner photo-sensitive cells that move that use more, collocation travel mechanism is to realize the purpose of flat scanning, and its volume is difficult to reduction, is difficult to especially incorporate in the structure of known optical touch screen.Again, it shows that touch area has been covered with pixel display unit and as the light sensing unit of touch-control known optical touch screen, has not had the sensing element that other spaces can be used for the configuration scanner.On the contrary, the present invention directly utilizes the light sensing unit of optical touch screen, makes it to produce simulating signal, and reacting the GTG of image on the file, and the optical touch screen need not to be provided with other extra Photosensing Units, and overall volume can remain unchanged.By this, the user can directly utilize optical touch screen of the present invention can finish the scan operation of file, need not extra scanner, so the present invention removes the scan function that can increase the optical touch screen, also can simplify user's scan operation, make comprehensive operation be achieved.
The present invention is described by above-mentioned related embodiment, yet the foregoing description is only for implementing example of the present invention.Must be pointed out that the embodiment that has disclosed does not limit the scope of the invention.On the contrary, change of being done and retouching without departing from the spirit and scope of the present invention all belongs to scope of patent protection of the present invention.
