Embodiment
In order to explain technology contents of the present utility model in more detail; illustrate as follows appended by also coordinating especially exemplified by specific embodiment; but the following drawings and embodiment are not to restriction of the present utility model; have in any art and usually know the knowledgeable; not departing from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is when being as the criterion depending on those as defined in claim.
With reference to the schematic top plan view of a kind of touch-screen that figure 1, Fig. 1 provides for the utility model embodiment, as shown in Figure 1, the touch-screen 100 that the utility model provides comprises: be multiplely arranged in array and the touch control electrode 10 insulated each other; Many touch-control lead-in wires 20, each touch-control lead-in wire 20 is electrically connected with a touch control electrode 10.Touch-screen 100 is self-capacitance touch screen, carry touching signals to touch control electrode 10 by touch-control lead-in wire 20, when the touching object such as finger are close to touch control electrode 10, due to human body electric field, a coupling capacitance is formed between finger and touch control electrode 10, the coupling capacitance formed can cause the change of touch control electrode 10 electric capacity over the ground itself, just can determine that finger is close to which or which touch control electrode 10, thus determine the touch location of finger by the changing value detecting this electric capacity.
Be described for finger as touching object, because the whether close of finger is determined by the changing value of the electric capacity in detection touch control electrode, therefore, the size of the changing value of electric capacity must have enough large value and just can accurately identify.Finger under normal circumstances with the contact area of the touch-screen area close to the circle of a diameter 5mm, therefore, the touch face of finger can be simplified to the circle (as shown in Fig. 2 upper left corner) of a diameter 5mm, data comparatively are intuitively obtained for the ease of simulation, touch control electrode can be simplified to square, Fig. 2 is that the touch face of the finger of diameter 5mm causes the changing value of electric capacity with the change curve schematic diagram of touch control electrode size, when other conditions are constant, artificial hand makes a comment or criticism face close to touch control electrode, obtain the variation tendency of changing value along with the size of touch control electrode of the electric capacity in touch control electrode (pad), as shown in Figure 2, the changing value of electric capacity is substantially large with the change of touch control electrode and present the trend of increase.Remove the impact of noise simultaneously, according to identification requirement, 50fF can be at least by the changing value of the electric capacity accurately detected, corresponding touch control electrode is at least the square of length of side 1.6mm thus, now, the touch area of finger is greater than touch control electrode, and finger can cover touch control electrode completely, that is, finger can not be less than 2.56mm with the contact area of touch control electrode
2.The shape of touch control electrode can be diversified, can be square, rectangle, circle or arbitrary polygon, and finger touch face is normally circular or oval, therefore under finger can cover the limiting case of whole touch control electrode, the size of touch control electrode must not be less than 2.56mm
2if the shape length in one direction of touch control electrode exceedes the coverage of finger, then the area of this touch control electrode must need more than 2.56mm
2the contact area pointed with touch control electrode just can be made can to reach at least 2.56mm
2.Certainly, the shape of touch control electrode can be rectangle, in order to ensure that finger and touch control electrode are just to when touching, touching area and necessarily can reach 2.56mm
2, the length of rectangle can be got and be widely all not less than 1.6mm, to reach accurate touch-control effect.
In addition, in order to improve touch precision, for the determination of touch location, not only to be judged by the variable quantity of electric capacity in the touch control electrode that is touched, also to consider that touching object is when touching a certain touch control electrode simultaneously, touching object is on the impact of the electric capacity of the touch control electrode around it, when touching object just carries out touch action to a certain touch control electrode, the capacitive effect of touching object to this touch control electrode four touch control electrode is up and down minimum, considers the relation between the size of touching object and touch control electrode for this situation.
The partial schematic diagram of the touch-screen that Fig. 3 provides for the utility model, as shown in Figure 3, nine touch control electrode 310 be arranged in array, 1-9 numbering is carried out to these 9 touch control electrode 310, when touching object just carries out touch action to touch control electrode 5, in figure, dash area is the region that touch action occurs, at this moment because the close of touching object can to touch control electrode 5 four touch control electrode 2 up and down, 4, 6 and 8 electric capacitys have an impact, and be basically identical on the impact of these four touch control electrode, therefore, one of choosing in these four touch control electrode is only needed to carry out the change of the electric capacity measured on it.Analogue simulation is carried out to touch situation as described in Figure 3, and the electric capacity measured respectively in the touch control electrode 4 after touching front and touch, the variable quantity of the electric capacity touched in the touch control electrode 4 of front and back is obtained as difference, the number percent of the electric capacity after the variable quantity that finally can obtain electric capacity accounts for and touches in touch control electrode 4, is referred to as electric capacitance change number percent.For different touch areas, the size of adjustment touch control electrode, obtains one group of data as following table 1.As in table 1, d is the diameter of touch area, and D is the length of side of square touch electrode, unit is mm, because computational accuracy is 0.50%, be then less than 0.50% for error, simultaneously, when touching object is close to touch control electrode, the electric capacity in touch control electrode should be improved, therefore, the variable quantity of electric capacity should be on the occasion of, namely final electric capacitance change number percent also should be on the occasion of, negative electricity volume change number percent is noise phenomena.
Table 1
Can see from table 1, when the length of side of touch control electrode exceedes the diameter of touch area, the electric capacitance change number percent in touch control electrode 4 substantially or be below accuracy value, or is negative value, present irregular change, electric capacitance change number percent is had no way of with reference to the determination carrying out position of touch; And when the length of side of touch control electrode is less than the diameter of touch area, electric capacitance change number percent be higher than precision on the occasion of, and under the size of same touch control electrode, along with the increase of touch area, electric capacitance change number percent is the trend increased substantially.Therefore, in order to utilize this capacitance change accurately to determine position of touch, the length of side of touch control electrode needs the diameter being less than touch area.Can also find out from table 1, when the length of side of touch control electrode equals the diameter of touch area, the electric capacity in touch control electrode 4 also has comparatively considerable variable quantity, but the value of electric capacitance change number percent is not highly stable, sometimes be higher than precision on the occasion of, be sometimes a little less than precision on the occasion of.
More than in emulation, the shape of touch control electrode is square, the shape of touch area is circular, touch area is just to touch control electrode 5, the result obtained in simulation result is, accurately position of touch is determined in order to utilize this capacitance change, the length of side of touch control electrode needs the diameter being less than touch area, in this case, touch area can touch four touch control electrode 2 around touch control electrode 5, 4, 6 and 8, therefore in touch control electrode 4, produce the change of comparatively objectively electric capacity, therefore, that is, no matter which type of shape is touch control electrode be, ensure that touch area is when just to touch a certain touch control electrode, other touch control electrode around this touch control electrode can be touched, then can improve the precision of touch-control location.Thus, make the area of touch control electrode be less than the area of touch area, then can ensure once to touch and can touch multiple touch control electrode, improve the precision of touch-control location.The situation of the diameter of touch area is equaled for the length of side of touch control electrode in simulation result, that is, touch area is just in the scope of touch control electrode 5, and touch control electrode 4 also presents the variable quantity of comparatively considerable electric capacity, although situation is not highly stable, but consider in actual touch action, the situation that touch area overlaps just with touch control electrode is there will be in few situation, therefore, the situation that the length of side of touch control electrode equals the diameter of touch area is also desirable, that is, the situation of the area of touch control electrode and the area equation of touch area is also desirable.And the area of touch area is relevant with touching object, under normal circumstances, all adopt finger to realize touch, and the size of the touch area of finger also can vary with each individual, also produce difference because of the difference of touching intensity simultaneously, the forefinger mean breadth of most of adult is 16 to 20 millimeters, when touching touch-screen, the half of about forefinger width can touch on touch-screen, touch area is approximately a diameter is the circle of 8mm, therefore, have to make touch-screen and touch experience preferably, only need by touching of finger and realize accurate touch-control, the length of side of touch control electrode is preferably not more than 8mm, from the area of touch control electrode, its area is preferably not more than 64mm
2.For the usual situation adopting the touch-screen of other touching object, the area of the touch area that usually can realize according to this touching object determines the size of touch control electrode, such as, under certain situation, expect to realize high-precision touch-control by the pointer that contact cotrol head is less, in this case just need touch control electrode to do very little, preferably do not exceed the touch area of pointer.Therefore, the area of touch area can be understood as the size of the touch area formed on the touchscreen when carrying out usual touch operation to touch-screen.
Another embodiment of the present utility model also provides a kind of touch-control display panel, the schematic cross-section of a kind of touch-control display panel that Fig. 4 a provides for the utility model, Fig. 4 a essentially describes the Presentation Function part in touch-control display panel, as shown in fig. 4 a, this touch-control display panel is display panels, this touch-control display panel comprises array base palte and color membrane substrates 102, be filled with liquid crystal (not illustrating in the drawings) between array base palte and color membrane substrates 102, liquid crystal molecule deflects and realizes display under the effect of electric field.

The schematic top plan view of a kind of touch-control display panel that Fig. 4 b provides for the utility model, Fig. 4 b essentially describes touch controllable function part in touch-control display panel, as shown in Figure 4 b, touch-control display panel 200 comprises: be multiplely arranged in array and the touch control electrode 210 insulated each other; Many touch-control lead-in wires 220, each touch-control lead-in wire 220 is electrically connected with a touch control electrode 210.Touch-control display panel 200 is self-capacitance touch display panel, carry touching signals to touch control electrode 210 by touch-control lead-in wire 220, when pointing close to touch control electrode 210, due to human body electric field, a coupling capacitance is formed between finger and touch control electrode 210, the coupling capacitance formed can cause the change of touch control electrode 210 electric capacity over the ground itself, just can determine that finger is close to which or which touch control electrode 210 by the changing value that detects aforementioned electric capacity, thus determine the touch location pointed.
The touch controllable function part of the touch-control display panel that Presentation Function part and Fig. 4 b illustrated embodiment of the touch-control display panel that Fig. 4 a illustrated embodiment can be provided provide is combined, substrate 191 in fig .4 can make touch control electrode and touch-control lead-in wire simultaneously, form touch-control display panel, but the Presentation Function part do not limited in touch-control display panel, such as, liquid crystal display (LiquidCrystalDisplay can be adopted, LCD), organic light-emitting diode display (OrganicLight-EmittingDiode, or Electronic Paper (E-paper) etc. OLED).When the Presentation Function part in touch-control display panel adopts liquid crystal display, in order to the height realizing showing with touch-control is integrated, touch control electrode can also be multiplexed with the public electrode in liquid crystal display, that is, an electrod assembly in touch-control display panel makes touch control electrode and public electrode two kinds of functions, such as, the public electrode 103 in the touch-control display panel shown in Fig. 4 a is used as touch control electrode simultaneously.In order to realize an electrod assembly two kinds of functions, the form that timesharing drives can be adopted, in the touch-control stage, to electrode input and output touching signals, to realize the function of touch control electrode; In the display stage to electrode input display common signal, to realize the function of public electrode, form electric field with the pixel electrode in touch-control display panel, thus the deflection of control liquid crystal molecule is to realize display.
It is similar that size setting principle and the size of touch control electrode in the touch-screen that the utility model provides for touch control electrode in touch-control display panel set principle, with reference to previous embodiment, can not repeat them here.According to the size setting principle of touch control electrode in previous embodiment, simultaneously according to the size of touch-control display panel, the applicable scope of the touch control electrode number that touch-control display panel can be arranged can be calculated.
Certainly, do not limit the shape of effective touch display area of touch-control display panel, the shape of effective touch display area of touch-control display panel comparatively conventional is at present rectangle, and the length ratio of the long limit of rectangle and broadside is generally 16:9 and 16:10.
For the rectangular touch display panel that length breadth ratio is 16:9, when being of a size of a inch (catercorner length of rectangular touch viewing area, wherein a is positive number), the long length of side of rectangular touch display panel is
millimeter (mm), is about 22.14a millimeter, and on long side direction, arrange at most the round values touch control electrode being not more than 13.84a, minimum setting is not less than a round values touch control electrode of 2.77a; The broadside length of rectangular touch display panel is
millimeter, is about 12.45a millimeter, and in broadside, arrange at most the round values touch control electrode being not more than 7.78a, minimum setting is not less than a round values touch control electrode of 1.56a.Therefore, touch control electrode is arranged in array along the long limit of rectangular touch display panel and broadside, length breadth ratio be a inch of 16:9 rectangular touch display panel on can arrange at most and be not more than 107.67a
2a round values touch control electrode, minimum needs arrange and are not less than 4.32a
2a round values touch control electrode, the number due to touch control electrode can only be positive integer, therefore for extreme situation, can get 107.67a
2integral part and 4.32a
2the integral part of+1.
Equally, be the rectangular touch display panel of 16:10 for length breadth ratio, when being of a size of b inch (catercorner length of rectangular touch viewing area, wherein b is positive number), the long length of side of rectangular touch display panel is
millimeter (mm), is about 21.54b millimeter.According to the requirement of above-mentioned accurate identification touch-control, on long side direction, arrange at most the round values touch control electrode being not more than 13.46b, minimum setting is not less than a round values touch control electrode of 2.69bb; The broadside length of rectangular touch display panel is
millimeter, is about 13.46b millimeter, and in broadside, arrange at most the round values touch control electrode being not more than 8.41b, minimum setting is not less than a round values touch control electrode of 1.68b.Therefore, touch control electrode is arranged in array along the long limit of rectangular touch display panel and broadside, length breadth ratio be the b inch of 16:10 rectangular touch display panel on can arrange at most and be not more than 113.24b
2a round values touch control electrode, minimum needs arrange and are not less than 4.52b
2a round values touch control electrode, the number due to touch control electrode can only be positive integer, therefore for extreme situation, can get 113.24b
2integral part and 4.52b
2the integral part of+1.
Above-mentioned is that the touch-control display panel being rectangle with the shape of effective touch display area is illustrated, but nowadays the application of irregular display is more and more extensive, for the touch-control display panel comprising irregular touch display area, it generally includes rectangular touch viewing area and other erose touch display area, for rectangular touch viewing area, be of a size of the p inch (catercorner length of rectangular touch viewing area, wherein p is positive number) time, the number of it touch control electrode comprised is no less than 3.175p, the no more than 126p of number of described touch control electrode
2.Particularly, for the rectangular touch viewing area being of a size of p inch, when this rectangle for area during square is maximum, in this case, the size of touch control electrode according to minimum value, then the maximal value of the number of the touch control electrode that the rectangular touch viewing area obtaining p inch can be arranged; On the contrary, if the rectangular area that one, the rectangular touch viewing area of p inch is long and narrow, then area is relatively little, in this case, the size of touch control electrode according to maximal value, then the minimum value of the number of the touch control electrode that the rectangular touch viewing area obtaining p inch can be arranged.For long and narrow rectangular touch viewing area, the broadside that rectangle is shorter can only arrange a touch control electrode, the longer long limit approx. dimension of rectangle is p inch, therefore, can obtain the minimum value of the number of touch control electrode for being not less than 3.175p.
Restriction for the number to touch control electrode on touch-control display panel provided in above-described embodiment is equally applicable to the restriction of the touch control electrode number in the utility model on touch-screen.
Changing value except electric capacity in touch control electrode can affect the size and shape of the touch control electrode on touch-control display panel, thus affects the number of the touch control electrode that touch-control display panel is arranged, and the quantity of touch-control lead-in wire also can limit the quantity of touch control electrode.Because each touch control electrode all needs at least to go between with a touch-control to be electrically connected, and each touch-control lead-in wire all needs to be separately connected to integrated circuit portion to obtain touching signals or display common signal, particularly under the demand of the narrow frame of touch-control display panel, the installation space of touch-control lead-in wire is limited, the number limit value of the touch-control lead-in wire that simultaneously can arrange under process conditions, the live width that all can affect touch-control lead-in wire on the requirement of the resistance sizes of touch-control lead-in wire and the set-up mode etc. of touch-control lead-in wire and the finite space.Touch-control lead-in wire is electrically connected to the situation of the electrode of multiple separate, mutually insulated simultaneously, because the touching signals of multiple electrode input and output is here all identical, therefore can regards this multiple electrode integral as a touch control electrode.
