Description

Technical Field

[0001] The present application relates to the field of touch screen interaction technology, and in particular to a method, device, electronic device, medium and display device for determining a touch point. Background Art

[0002] As the demand for 3D display increases, the technical requirements for 3D interaction are also increasing. Currently, touch interaction at a distance of more than 100mm from the display screen can be processed by the camera, but when the distance is less than 100mm, a large area of ​​the lens imaging is blocked and the features cannot be recognized. Other detection methods such as capacitive touch detection are needed to identify interactive actions.

[0003] For touch detection of capacitive touch panels, the conventional detection method is to directly select the point with the largest touch signal as the touch point. However, due to the limitations of the finger touch method, in many cases the signal amount of the point corresponding to the fingertip is not the largest.

[0036] Embodiment 1

[0037] Figure 1 FIG. 1 is a flow chart of a method for determining a touch point according to an embodiment of the present disclosure, comprising:

[0038] Step S110, determining at least one candidate sensing unit according to the touch information fed back by each sensing unit in the display panel; wherein the touch information includes the signal amount and touch depth of the touch signal corresponding to each point in the sensing unit, and each sensing unit corresponds to at least one point;

[0039] Step S120, determining a target sensing unit from at least one candidate sensing unit;

[0040] Step S130, determining the touch point according to the target sensing unit.

[0041] Exemplarily, the method of this embodiment is applicable to a terminal using a capacitive display panel, such as a mobile phone or a tablet computer, etc. The capacitive display panel can be TDDI (Touch and Display Driver Integration), Incell (an embedded touch panel), Oncell (an external touch panel), Hybridincell (another embedded touch panel), GFF (Glass-Film-Film, an external touch panel), GG (Glass-Glass, another external touch panel), etc. Among them, the touch depth represents the distance between the touch object corresponding to the touch signal detected by the capacitive sensor in the sensing unit of the display panel and the display panel, and the signal amount of the touch signal is inversely proportional to the touch depth, that is, the larger the signal amount, the smaller the touch depth.

[0042] In the existing capacitive touch detection technology, the default method of finger touch screen is usually standard touch, that is, the distance between the fingertip performing the floating touch operation and the display panel is the smallest, so the point with the largest signal will be directly determined as the touch point of the fingertip. However, in the actual use process of users, there are many non-standard touch methods, and the position corresponding to the fingertip is not the point with the largest signal. In this case, if the point with the largest signal is still directly used as the touch point, there is a high probability that the touch point identified by the display panel is not the real touch point, which will affect the recognition of subsequent clicks, strokes or rotations.

[0043] Therefore, in order to more accurately identify the actual touch point of the capacitive display panel under different touch modes, the method of this embodiment needs to determine at least one candidate sensing unit where the touch point may exist in each sensing unit based on the touch information fed back by each sensing unit in the display panel, that is, the characteristic distribution of the signal quantity, and further lock the target sensing unit where the touch point is located in the candidate sensing unit, and then determine the touch point in the target sensing unit.

[0044] In one embodiment, in step S110, at least one candidate sensing unit is determined based on touch information fed back by each sensing unit in the display panel, including: determining a first touch depth of a point with a maximum signal amount in the display panel, and determining a first depth interval based on the first touch depth; wherein the value of the first touch depth is a minimum depth value in the first depth interval; determining at least one first sensing unit in each sensing unit based on the first depth interval; wherein there is at least one point in the first sensing unit where the touch depth of the touch signal corresponding to the touch depth is in the first depth interval; and determining at least one candidate sensing unit based on a relationship between the number of first sensing units and a preset first number threshold.

[0045] Exemplarily, assuming that the user's current touch mode is a standard touch mode that can be recognized by conventional capacitance detection methods, the point with the maximum signal amount is the touch point corresponding to the fingertip, and the touch depths corresponding to other fingers on the display panel other than the touching finger can be predicted. For example, if the index finger is used for touch, the touch depths of the curled middle finger and ring finger are predicted, and the first touch depth at the point with the maximum signal amount is used as the minimum depth value, and the first depth interval is constructed with the predicted touch depths corresponding to other fingers on the display panel as the maximum depth value. Then, when the touch mode is the standard touch mode, the touch signal with a touch depth in the first depth interval corresponds to the touching finger and other fingers adjacent to the touching finger. Therefore, based on the size range of normal fingers and the size of the sensing unit, a first quantity threshold can be preset, so that the user's current touch mode can be judged according to the relationship between the number of sensing units corresponding to the touch signal in the first depth interval and the first quantity threshold. The touch mode can include standard touch and non-standard touch, and candidate sensing units are further determined in each sensing unit of the display panel according to the touch mode.

[0046] In one embodiment, Figure 2 The figure shows a hand posture when a user touches a capacitive display panel using a standard touch method (such as a vertical touch method). According to actual statistical measurements, the height difference between the other curled fingers and the touching fingers is generally about 4 mm to 6 mm. Therefore, the difference between the maximum depth value in the first depth interval and the first touch depth is greater than or equal to 4 mm and less than or equal to 6 mm. Preferably, the difference between the maximum depth value in the first depth interval and the first touch depth can be 5 mm, that is, if the first touch depth is h1, the first depth interval is [h1, h1+5mm].

[0047] Figure 3 is with Figure 2 Schematic diagram of signal quantity distribution of touch signals in each sensing unit in the capacitive display panel corresponding to the touch mode, wherein the sensing units in area a and area b both have points where the touch depth is in the first depth interval, there is only one sensing unit in area a and its touch depth is smaller than that of the sensing unit in area b, since the length and width of the sensing unit are generally about 3mm to 4mm, and the diameter of a normal finger does not exceed 9mm, the first quantity threshold can be set accordingly, for example, the first quantity threshold is set to 9, if the number of sensing units corresponding to the touch signal in the first depth interval (the number of sensing units in area a and area b) is not greater than 9, such as Figure 3 If the number of sensing units in area a and area b shown in the figure is 9, it can be determined that the current touch mode is standard touch. Conversely, if the number of sensing units corresponding to the touch signal in the first depth interval is greater than 9, it can be determined that the current touch mode is non-standard touch.

[0048] In one embodiment, when the number of first sensing units is not greater than a first number threshold, that is, when the touch mode is standard touch, determining at least one candidate sensing unit in step S110 includes: determining a sensing unit that meets a first preset condition as a candidate sensing unit, wherein the first preset condition is that there is at least one point in the sensing unit and the touch depth of the touch signal corresponding to the touch depth is the first touch depth.

[0049] Understandably, Figure 3 The situation in which there is only one sensing unit corresponding to the minimum touch depth shown in is an ideal situation. In actual operation, the corresponding position of the fingertip of the touching finger on the display panel may not be in a single sensing unit, for example, it may be at the junction of multiple sensing units. In some individual cases, due to the influence of the touch angle, the touch depth of the fingertips of other fingers may be consistent with the touch depth of the fingertip of the touching finger, resulting in the minimum touch depth (first touch depth) appearing in multiple non-adjacent display units. The touch depth of the touch signal corresponding to at least one point is the first touch depth and can be taken as a candidate sensing unit, and then the target sensing unit where the touch point is located is determined by further identification and judgment among the candidate sensing units.

[0050] In one embodiment, when the touch mode is a standard touch, determining a target sensing unit from at least one candidate sensing unit in step S120 includes: determining the number of first points in each candidate sensing unit, the touch depth of the touch signal corresponding to the first point being the first touch depth; and determining the candidate sensing unit with the largest number of first points as the target sensing unit.

[0051] It can be understood that when there are more than one candidate sensing units, if the touch depth of the touch signal is the first touch depth (minimum touch depth) and the part is concentrated at the junction of adjacent sensing units, if the number of points with the touch depth of the first touch depth in a candidate sensing unit is more, it means that the area of ​​the positive projection of the fingertip of the touching finger on the candidate sensing unit is larger, then the candidate sensing unit is compared with other candidate sensing units. Therefore, the candidate sensing unit can be determined as the target sensing unit, and it is determined that the real touch point exists in the candidate sensing unit.

[0052] In one embodiment, when the number of first sensing units is greater than the first threshold, that is, when the touch mode is non-standard touch, determining at least one candidate sensing unit in step S110 includes: determining a point with a minimum signal amount and a second touch depth thereof in each point corresponding to a valid touch signal in the display panel; wherein the signal amount of the valid touch signal is greater than a preset touch determination threshold; determining a second depth interval according to the second touch depth; wherein the value of the second touch depth is a maximum depth value in the second depth interval; determining at least one candidate sensing unit according to the second depth interval; wherein there is at least one point in the candidate sensing unit where the touch depth of the touch signal corresponding to the touch depth is in the second depth interval.

[0053] It can be understood that in the case of non-standard touch, the touch depth of the touch signal of the fingertip detected by the sensing unit is not the minimum touch depth. Therefore, the minimum signal point and its corresponding second touch depth can be determined first. The second touch depth represents the maximum touch depth among the points where the signal amount detectable by the sensing unit of the capacitive display panel is greater than the preset touch judgment threshold (that is, the maximum distance between the part of the user's hand that may be the touching fingertip and the display panel that the sensing unit can detect), so as to set the second depth interval according to the second touch depth, determine the second touch depth as the maximum depth value in the second depth interval, and reasonably set the minimum depth value in the second depth interval according to the hand size, so that the second depth interval includes the depth value corresponding to the real touching fingertip, and determine the sensing unit with the touch depth of the touch signal corresponding to at least one point in the second depth interval as a candidate sensing unit.

[0054] Figure 4 FIG. 4 shows a hand gesture of a user touching a capacitive display panel by a non-standard touch method (such as finger tilt touch). Figure 4 As shown, the touching finger is the index finger of the user, but the touch depth value corresponding to the index finger is larger, and the touch depth values ​​corresponding to the fingertips of other fingers, such as the curled index finger, ring finger and little finger, are all smaller than the touch depth of the index finger. Therefore, the point with the largest signal amount cannot be directly used as the touch point. In the case of tilted finger touch, according to actual statistical measurements, the height difference between the touch depth of other positions of the hand and the point corresponding to the minimum signal amount is approximately 6mm to 10mm. Therefore, the difference between the second touch depth and the minimum depth value in the second depth interval can be set to be greater than or equal to 6mm and less than or equal to 10mm. Preferably, the difference between the second touch depth and the minimum depth value in the second depth interval can be 8mm, that is, if the second touch depth is h2, the second depth interval is [h2-8mm, h2].

[0055] In one embodiment, when the touch mode is non-standard touch, determining a target sensing unit from at least one candidate sensing unit in step S120 includes: determining the number of second sensing units adjacent to each candidate sensing unit; wherein the second sensing unit is a sensing unit having a valid touch signal; and determining a candidate sensing unit whose number of adjacent second sensing units is not greater than a preset second number threshold as a target sensing unit.

[0056] Figure 5 is with Figure 4 A schematic diagram of the signal quantity distribution of touch signals in each sensing unit in the capacitive display panel corresponding to the touch mode in the middle, wherein the sensing units in the c area and the d area are candidate sensing units, and the sensing units in the e area have valid touch signals but the touch depth is not in the second depth interval. Therefore, it is necessary to determine the target sensing unit in the c area and the d area, and according to the hand structure, there should be more sensing units without valid touch signals around the sensing unit corresponding to the fingertip of the touching finger, and the number of sensing units with valid touch signals around the sensing unit corresponding to the fingertip of the touching finger is generally greater than the number of sensing units with valid touch signals around the sensing unit corresponding to the fingertip, so it is only necessary to reasonably set the second quantity threshold and determine the number of second sensing units (sensing units with valid touch signals) adjacent to each sensing unit in the candidate sensing units, so as to determine the target sensing unit in the candidate sensing units.

[0057] like Figure 5 As shown in , there are 8 sensing units adjacent to each sensing unit. For example, the second quantity threshold is set to 3. Among the sensing units in area c and area d, only one sensing unit in area c has a number of second sensing units adjacent to no more than 3. Therefore, the sensing unit can be determined as the sensing unit corresponding to the fingertip (that is, the target sensing unit), and the candidate sensing unit in area d can be determined as the sensing unit corresponding to the fingertip.

[0058] By adopting the method of this embodiment, when the real touch point is not the point with the maximum signal amount, the area where the real touch point is located (candidate sensing unit) can be preliminarily determined according to the point with the minimum signal amount, and then the target sensing unit where the real touch point is located can be determined according to the number of sensing units with valid touch signals adjacent to each candidate sensing unit. This allows the recognition of the real touch point under different touch modes, thereby improving the accuracy and fluency of touch screen interaction.

[0059] In one embodiment, determining the touch point according to the target sensing unit in step S130 includes: determining at least one third point with the largest signal amount among the points of the target sensing unit, and determining the touch point according to the third point.

[0060] It can be understood that no matter whether the standard touch method or the non-standard touch method is used to touch the capacitive display panel, after determining the target sensing unit where the actual touch point is located, the actual touch point can be considered to be the point with the largest signal in the target sensing unit. If there is only one point with the largest signal, this point can be directly determined as the touch point. If there are multiple maximum signal points with the same signal amount, the center point of these points can be fitted as the touch point. Alternatively, individual points among the multiple maximum signal points that are obviously far away from other maximum signal points can be determined as error points. After the error points are eliminated, the touch point is determined only based on other maximum signal points.

[0061] If the two mutually perpendicular directions of the plane where the capacitive display panel is located are the x-axis and the y-axis, and the direction perpendicular to the plane where the capacitive display panel is located is the z-axis, a three-dimensional coordinate system is established, such as Figure 6 As shown, for any hand point corresponding to the user's hand in the three-dimensional coordinate system, its x-axis coordinate and y-axis coordinate can represent the position of its positive projection on the capacitive display panel, and the z-axis coordinate can represent the distance between the hand point and the capacitive display panel, that is, the touch depth of the touch signal generated by the hand point detected by the sensing unit.

[0062] Figure 7 This is an embodiment of the present disclosure. Figure 6 A flow chart of touch point recognition based on the coordinate system. When the sensing unit of the capacitive display panel detects a touch signal, each point with a valid touch signal and its corresponding signal amount will be reported to the control system in the form of two-dimensional coordinates (including x-axis coordinates and y-axis coordinates). The control system will determine the point with the maximum signal amount, and calculate the first touch depth of the point with the maximum signal amount. According to the first touch depth and the first depth interval [h1, h1+5mm], the number of first sensing units with touch depths of the points in the first depth interval is counted at the same time, and the way in which the finger touches the capacitive display panel is determined according to the relationship between the number of first sensing units and the preset first number threshold, for example Figure 7 The first quantity threshold is set to 9, then when the number of the first sensing units is less than or equal to 9, the touch mode is determined to be standard touch, and the point with the maximum signal amount can be determined as the touch unit.

[0063] When the number of first sensing units is greater than 9, it can be determined that the touch mode is non-standard touch, and the second touch depth of the point with the minimum signal amount can be determined among the points with valid touch signals, and the second depth interval [h2-8mm, h2] is determined according to the second touch depth. At the same time, the sensing units with touch depths of the points in the second depth interval are counted and these sensing units are determined as candidate sensing units, and then the number of second sensing units with valid touch signals adjacent to each candidate sensing unit is counted. If the number of second sensing units adjacent to a candidate sensing unit is less than or equal to 3, the candidate sensing unit is determined to be the target sensing unit corresponding to the fingertip, and the touch point is further determined in the target sensing unit; if the number of second sensing units adjacent to a candidate sensing unit is greater than 3, the candidate sensing unit is determined to correspond to the hand position of the fingertip or other non-touching fingertip.

[0064] It should be noted that the various quantity thresholds and the first depth interval and the second depth interval in the embodiments of the present application need to be determined based on the size of the sensing unit and the size of a normal finger. The specific values ​​mentioned in the embodiments are only for illustration. In actual applications, they can be reasonably set according to the actual size. The present application is not limited to this.

[0065] The method of this embodiment can distinguish different touch methods and adopt different touch point recognition strategies according to the relevant size parameters of the capacitive display panel and the size parameters of a normal finger. It can overcome the problem of poor touch point recognition accuracy caused by non-standard touch methods when the user touches a terminal with a capacitive display panel, thereby ensuring the accuracy and smoothness of touch screen interaction.
