The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] First, see Figure 1 , Figure 1 A schematic diagram of a screen correction system provided in an embodiment of the present application.

[0061] Exemplarily, the screen correction system may include a touch device, a correction device and a database. Among them, the touch device may be a vehicle-mounted central control, a smart phone (such as an Android phone, an iOS phone, a Windows Phone phone, etc.), a tablet computer, a PDA, a laptop computer, a mobile Internet device MID (Mobile Internet Devices, referred to as: MID), a robot or a wearable device and other operable devices with touch functions, and this application does not make specific restrictions on this. The correction device may be a server, for example, it may be an independent server, or it may be a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content distribution networks (Content Delivery Network, CDN), and basic cloud computing services such as big data and artificial intelligence platforms, and this application does not make specific restrictions on this. The database may also be a server, or a memory that provides data storage services, such as: read-only memory (ROM) or other types of static storage devices that can store static information and instructions, random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, and the present application does not make specific limitations on this.

[0062] Specifically, the screen of the touch device is a touch screen, which can be any type of touch screen, such as: vector pressure sensing touch screen, resistive touch screen, capacitive sensing touch screen, infrared touch screen, optical imaging touch screen, surface acoustic wave touch screen, etc. This application does not impose any restrictions on this.

[0063] In this embodiment, when the user touches the touch screen of the touch device, the touch screen acquires characteristic parameters and detection parameters according to its own characteristics for realizing touch recognition and the environment in which the current device is located. The characteristic parameters refer to parameters for realizing touch recognition based on the touch principle of the touch screen. The detection parameters refer to parameters that assist the touch screen in recognizing whether the touch is valid, or other parameters that affect the touch recognition of the touch screen, such as environmental parameters of the screen operating environment: any one of temperature parameters, humidity parameters and light sensitivity parameters. At the same time, the characteristic parameters and the detection parameters can be parameters of the same category or different categories. Exemplarily, for a vector pressure sensing touch screen, its characteristic parameter is a pressure parameter, and the detection parameters may include at least one of the following: a pressure parameter, a temperature parameter, and a humidity parameter; for a resistive touch screen, its characteristic parameter is a resistance parameter, and the detection parameters may include at least one of the following: a pressure parameter, a resistance parameter, a temperature parameter, and a humidity parameter; for a capacitive sensing touch screen, its characteristic parameter is a capacitance parameter, and the detection parameters may include at least one of the following: a pressure parameter, a capacitance parameter, a temperature parameter, and a humidity parameter; for an infrared touch screen, its characteristic parameter is a temperature parameter and / or an infrared parameter, and the detection parameters may include at least one of the following: a pressure parameter, an infrared parameter, a temperature parameter, and a humidity parameter; for an optical imaging touch screen, its characteristic parameter is a light sensitivity parameter, and the detection parameters may include at least one of the following: a light sensitivity parameter, a brightness parameter, a wavelength parameter, a temperature parameter, and a humidity parameter; for a surface acoustic wave touch screen, its characteristic parameter is an acoustic wave parameter, and the detection parameters may include at least one of the following: a pressure parameter, an acoustic wave parameter, a temperature parameter, and a humidity parameter.

[0064] The following will take a capacitive touch screen as an example to explain in detail the screen calibration method provided by the present application. Based on this, the "touch screen" below defaults to "capacitive touch screen" unless otherwise specified. The calibration methods for other types of screens are similar to those for capacitive touch screens and will not be described in detail here.

[0065] In this embodiment, due to the user's touch, the touch screen generates capacitance parameters and pressure parameters, wherein the capacitance parameters are characteristic parameters of the touch screen, and the capacitance parameters and pressure parameters are detection parameters of the touch screen. The touch device obtains the capacitance parameters and voltage parameters, and determines the effective preset range of the capacitance parameters based on the capacitance parameters and voltage parameters, and calibrates the touch screen.

[0066] In this embodiment, the detection parameters may also include temperature parameters and humidity parameters, which are obtained by the temperature sensor and the humidity sensor respectively. When calibrating the screen, the touch device may also determine the offset of the touch screen under the current temperature and humidity according to the temperature parameters and the humidity parameters, and then offset the effective preset range in the same manner, and then calibrate the touch screen through the offset effective preset range.

[0067] Therefore, by obtaining the characteristic parameters and detection parameters generated when the screen is touched, the effective threshold range in which the screen can correctly identify the touch under the touch condition is determined, and the screen is calibrated. Therefore, the screen can be automatically calibrated by the characteristic parameters and detection parameters generated when touched. Compared with the calibration method in the prior art that requires the user to click multiple times for multiple data collection, the method provided by this application is simpler and does not require the user to devote energy to cooperate. It can then achieve fast and accurate calibration of the touch screen, greatly improving the user experience.

[0068] Secondly, it should be noted that the screen calibration method provided in the embodiment of the present application can be applied to the touch calibration scenarios of in-vehicle central control, smart phones, numerical control equipment, tablet computers and other devices. Below, the touch calibration scenario of the in-vehicle central control device is taken as an example to illustrate a touch calibration method proposed in the present application. The touch calibration methods in other scenarios are similar to the methods in the touch calibration scenario of the in-vehicle central control device, and will not be repeated here.

[0069] See also Figure 2 , Figure 2 A schematic diagram of a touch screen of a vehicle-mounted central control device provided in an embodiment of the present application. In this embodiment, the touch screen may include a display screen, a cover plate, and a pressure sensor. The pressure sensor is at least partially overlapped with the display screen. Specifically, Figure 2 In the example shown, the pressure sensor can be arranged around the display screen and completely surround the display screen. The cover plate is arranged above the display screen and the pressure sensor, and covers the display screen and the pressure sensor. Therefore, when the user touches the touch screen, it first contacts the cover plate, and then the pressure display arranged under the cover plate can sense the pressure change on the cover plate, and then generate the pressure parameters. At the same time, since the pressure sensor is arranged around the display screen, the pressure sensor can sense the pressure at any position in the display area. Therefore, when calibrating, the user can complete the calibration of the touch screen at any position in the display area corresponding to the touch screen display, which simplifies the operation and improves the user experience.

[0070] In an optional implementation, the pressure sensor may not completely surround the display screen, for example, it may be disposed on one side of the display screen. Figure 3 As shown, Figure 3A schematic diagram of a touch screen of another vehicle-mounted central control device provided for an embodiment of the present application, in this embodiment, the pressure sensor is arranged on the upper side of the display screen. At this time, the part where the effective detection range of the pressure sensor overlaps with the display area of ​​the display screen is the touch calibration area. When the touch screen needs to be calibrated, the user needs to touch any position in the touch calibration area to complete the collection of pressure parameters and capacitance parameters. In this embodiment, although the touch calibration area has become smaller, the number of pressure sensors used has also been reduced, and the impact is only to reduce the touch calibration area. Therefore, the cost of the equipment is reduced without causing particularly complicated operations.

[0071] Specifically, the pressure sensor can use a micro-pressure strain gauge to sense the touch force by sensing the deformation of the surface of the pressure-sensitive material. When the pressure sensor is subjected to elastic deformation or tensile deformation, its body resistance value will change significantly. When the user touches the cover, the pressure sensor attached to the bottom of the cover will deform with the cover due to the touch action, causing the resistance value of the pressure sensor to change. The pressure sensor converts the physical deformation generated when touching the cover into an electrical signal that can be collected and processed and transmitted to the calibration device by detecting the change in resistance value.

[0072] The following will take the touch correction scenario of the capacitive touch screen of the vehicle-mounted central control device as an example to explain in detail a screen correction method proposed in this application.

[0073] See also Figure 4 , Figure 4 A flowchart of a screen correction method provided in an embodiment of the present application is provided. The method is applied to the screen correction system in the above embodiment. The correction method may include the following steps:

[0074] 401: Get feature parameters and detection parameters.

[0075] In this embodiment, the characteristic parameters and detection parameters are parameters when the screen is touched, wherein the characteristic parameters refer to parameters for realizing touch recognition based on the touch principle of the touch screen. The detection parameters refer to parameters that assist the touch screen in recognizing whether the touch is valid, or other parameters that affect the touch recognition of the touch screen. At the same time, the characteristic parameters and the detection parameters can be parameters of the same category or different categories. For a capacitive inductive touch screen, the principle of its touch recognition is that the touching object forms a coupling capacitor with the working surface of the screen, resulting in a change in the capacitance value of the screen to be corrected. Therefore, its characteristic parameters are capacitance parameters, and the detection parameters may include at least one of the following: pressure parameters, capacitance parameters, temperature parameters, and humidity parameters. Among them, the pressure parameters and capacitance parameters are generated when the touch screen is touched, and the temperature parameters and humidity parameters can be obtained by the temperature sensor and the humidity sensor, and can also be obtained when the touch screen is not touched.

[0076] In this embodiment, since a touch can be regarded as an event occurring within a time period, the pressure parameter can refer to the pressure value received by the touch screen during the time period of the touch. Similarly, the capacitance parameter can refer to the capacitance value of the touch screen during the time period of the touch.

[0077] 402: Determine a valid threshold range of the characteristic parameter according to the characteristic parameter and the detection parameter.

[0078] In this embodiment, the method of determining the effective threshold range of the characteristic parameter is different according to the different detection parameters. As described above, the detection parameter of the capacitive touch screen can be at least one of a pressure parameter, a capacitance parameter, a temperature parameter, and a humidity parameter. Below, the method for determining the effective threshold range of the characteristic parameter will be described with specific examples of some detection parameters. It should be understood that the following examples are only examples provided to assist in understanding step 402, and do not limit step 402 to the following range.

[0079] (1) The detection parameters are pressure parameters and capacitance parameters:

[0080] like Figure 5 As shown, in this embodiment, when the detection parameters are pressure parameters and capacitance parameters, it means that the touch screen has detected a touch event. Touch events can be divided into valid touches and invalid touches, wherein a valid touch refers to a touch event that is an intentional subjective touch by the user, a touch with a clear purpose of use, and needs to be recognized as valid by the touch screen. An invalid touch refers to a touch event that is an unintentional false touch by the user, or a touch caused by other factors other than the user, such as the touch of flying insects, objects, etc. with the screen to be corrected, and the touch screen does not need to make an effective recognition response to it. From this, it can be seen that an invalid touch is not a touch event that the user intends to use the screen to be corrected, and therefore, an invalid touch has no reference significance for the correction of the screen. Then, before determining the effective threshold range of the characteristic parameter, it is necessary to determine whether the touch event is a valid touch or an invalid touch.

[0081] In this embodiment, it can be determined whether the current touch is a valid touch based on the characteristic parameters and the detection parameters. Specifically, when the touch screen is being touched, the characteristic parameters and the detection parameters will change accordingly with the degree of touch. At this time, the first capacitance parameter value and the first pressure parameter value of the touched area on the touch screen at the first moment are obtained; as well as the second capacitance parameter value and the second pressure parameter value at the second moment. Exemplarily, the first moment is before the second moment, for example: the first moment may be the moment when the touch starts, and the second moment may be the moment when the touch ends. Then, based on the first capacitance parameter value and the second capacitance parameter value, the changing trend of the capacitance parameter can be determined. Similarly, based on the first pressure parameter value and the second pressure parameter value, the changing trend of the pressure parameter can be determined.

[0082] In an optional implementation, the pressure parameter value and the capacitance parameter value in the time period between the first moment and the second moment may be obtained, and then the change trend of the capacitance parameter and the change trend of the pressure parameter may be determined according to the pressure parameter value and the capacitance parameter value in the time period.

[0083] In this embodiment, after obtaining the change trend of the capacitance parameter and the change trend of the pressure parameter, the change trend of the capacitance parameter and the change trend of the pressure parameter are compared. When the change trend of the capacitance parameter and the change trend of the pressure parameter are consistent, the touch event that generates the current pressure parameter and capacitance parameter is considered to be a valid touch. Exemplarily, if the first moment is the start moment of the touch event and the second moment is the end moment of the touch event, then for a normal valid touch event, after contacting the cover of the touch screen, an inward pressing pressure will be generated, and the pressure will be continuously pressed down first, and then gradually reduced until it leaves the screen. Thus, during the touch process, the contact surface between the touch object and the cover will first increase and then decrease, so that the capacitance value of the screen will show a trend of first increasing and then decreasing, and the pressure will first show a trend of first increasing and then decreasing. Therefore, when the change trend of the capacitance parameter and the change trend of the pressure parameter are consistent, both of them will first increase and then decrease, and when the changes of the two are also consistent with each other, the touch event can be determined to be a valid touch.

[0084] In this embodiment, since some false touches may also have similar characteristics as described above, the touch events with the same change trend of capacitance parameters and pressure parameters can be further screened. Exemplarily, the above touch events with capacitance parameters within the effective range of capacitance values ​​or pressure parameters within the effective range of pressure values ​​can be determined as valid touch events. Specifically, if the capacitance parameter is within the effective range of capacitance values, it means that the capacitance value change generated by the current touch event is within the capacitance value change range of the previous effective touch event. It is highly likely that the touch object that triggers the touch event is the same touch object as the touch object that triggers the effective touch event in history, and it can be determined that this touch event is caused by the same touch object touching the screen, and the possibility that this touch event is a valid touch is also high, and the current touch event can be determined to be a valid touch. Similarly, if the pressure parameter is within the effective range of pressure values, it means that the pressure value change caused by this touch event is within the pressure value change range of the previous effective touch event, and the similarity between the touch event and the effective touch event is high, and it can be considered that the same touch event as the effective touch event in history has occurred, and the current touch event can be determined to be a valid touch. Therefore, as long as either the capacitance value change parameter or the pressure change parameter satisfies the corresponding condition, the touch event detected by the capacitance parameter and the pressure parameter change trend can be determined as a valid touch.

[0085] In this embodiment, when the touch event is determined to be a valid touch, it means that the touch event is a conscious and purposeful touch by the user, and the capacitance value change of the screen caused by the touch, that is, the capacitance parameter should be identified. Then, the effective base value can be determined based on the capacitance parameter, and the effective base value can be expanded to obtain the effective threshold range of the capacitance parameter.

[0086] Exemplarily, a value can be randomly selected within the range of the capacitance parameter as the effective base value r, or the median of the range of the capacitance parameter can be used as the effective base value r. Then, according to the device parameters of the touch screen, the parameter extension range is determined as the tolerance t. Then, with the effective base value r as the center, according to the parameter extension range, the effective base value r is extended forward and backward to obtain the effective threshold range of the capacitance parameter [rt, r+t]. It should be noted that other methods for determining and extending the effective base value are also applicable to the present application, and the present application does not limit this.

[0087] (2) The detection parameters are temperature parameters and humidity parameters:

[0088] like Figure 6As shown, in this embodiment, when the detection parameters are temperature parameters and humidity parameters, the offset characteristics of the characteristic parameters of the touch screen in the environment corresponding to the temperature parameters and humidity parameters can be determined according to the historical data, temperature parameters and humidity parameters, and then the adjustment rules for correcting the offset can be determined according to the offset characteristics. The adjustment rules can be determined in advance and associated with the corresponding temperature parameters and humidity parameters, and then the effective base value can be directly called according to the temperature parameters and humidity parameters when used.

[0089] Then, the effective threshold range of the capacitance parameter determined in the last effective touch can be obtained, and the effective threshold range can be adjusted according to the adjustment rule to obtain the effective threshold range of the capacitance parameter that can normally trigger the touch screen to effectively identify under the environment corresponding to the adjustment rule.

[0090] (3) The detection parameters are pressure parameter, capacitance parameter, temperature parameter and humidity parameter:

[0091] like Figure 7 As shown, in this embodiment, when the detection parameters are pressure parameters, capacitance parameters, temperature parameters and humidity parameters, it is firstly determined whether the touch event generating the pressure parameters and capacitance parameters is a valid touch. The determination method is the same as the valid touch determination method in Example (1), and will not be repeated here.

[0092] In this embodiment, when determining that the touch event is a valid touch, a first valid threshold range of the capacitance parameter is determined based on the capacitance parameter. The first valid threshold range is determined in the same manner as the valid threshold range in description (1), and will not be described in detail here. Then, an adjustment rule is determined based on the temperature parameter and the humidity parameter. The adjustment rule is determined in the same manner as the adjustment rule in description (2), and will not be described in detail here.

[0093] Finally, the first effective threshold range is adjusted according to the adjustment rule to obtain an effective threshold range of the capacitance parameter that can normally trigger effective recognition of the touch screen under the environment corresponding to the adjustment rule.

[0094] 403: Correct the screen according to the effective threshold.

[0095] In this implementation, the capacitance value range that the touch screen recognizes as a valid touch can be updated to a capacitance parameter valid threshold range, thereby completing the calibration of the touch screen.

[0096] In summary, in the screen correction method provided by the present invention, by acquiring the characteristic parameters and detection parameters generated when the screen is touched, the characteristic parameters and detection parameters can reflect the impact of the current touch conditions on the screen. Then, based on the characteristic parameters and detection parameters, the effective threshold range in which the screen can correctly identify the touch under the touch condition can be determined. Finally, the screen is corrected according to the effective threshold range. Thus, the screen can be automatically corrected through the characteristic parameters and detection parameters generated when touched, which is simpler than the correction method in the prior art that requires the user to click multiple times for multiple data collections, thereby achieving fast and accurate correction of the screen to enhance the user experience.
