Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
it should be noted that, if not conflicted, the various features of the embodiments of the invention may be combined with each other within the scope of protection of the invention. Additionally, while functional block divisions are performed in apparatus schematics, with logical sequences shown in flowcharts, in some cases, steps shown or described may be performed in sequences other than block divisions in apparatus or flowcharts.
in the embodiment of the invention, tests show that the intensity of the electromagnetic radiation generated by the touch screen is related to the driving voltage of the touch screen, and the reduction of the driving voltage of the touch screen can effectively inhibit the intensity of the electromagnetic radiation. For example: the working voltage range of a touch screen of a certain type is 5V-10V, the touch screen is subjected to full-band (10 kHz-18 GHz) radiation test (test distance is 1m) in an electric wave darkroom, when the driving voltage is 10V, the maximum electromagnetic radiation value generated by the touch screen reaches 70dB (mu V/m), and when the driving voltage is reduced to 5V, the radiation intensity value of the whole frequency band is reduced to different degrees, and the maximum value is reduced to 50dB (mu V/m), so that the electromagnetic radiation generated by the touch screen can be effectively reduced by reducing the driving voltage of the touch screen, and the harm to a human body is reduced.
Based on this, the embodiment of the invention provides a driving method and device of a touch screen and an intelligent terminal. The driving method and device of the touch screen can be suitable for any type of intelligent terminal with the touch screen, such as: the touch screen control system comprises a smart phone, a smart television, a smart refrigerator, a robot, a tablet computer and the like, and is particularly suitable for smart terminals with touch screens in idle states for a long time, such as smart televisions. For example, a system setting option (or an application program) may be developed based on the inventive concept of the driving method of the touch screen provided by the embodiment of the present invention, a user may select to turn on or turn off the system setting option (or the application program) by himself, and when the user selects to turn on the system setting option (or the application program), the driving device of the touch screen provided by the embodiment of the present invention is started to regulate and control the driving voltage of the touch screen.
The driving method of the touch screen provided by the embodiment of the invention is a method for reducing the intensity of electromagnetic radiation generated by the touch screen by adjusting the driving voltage of the touch screen based on the use state of the touch screen. The touch signal detection is carried out by driving the touch screen by the first driving voltage V1 in the preset time period after the touch signal is received, if the next touch signal is not received in the preset time period, the user does not need to use the touch screen at the moment, the touch screen is driven by the second driving voltage V2 smaller than the first driving voltage V1 to carry out the touch signal detection, the electromagnetic radiation intensity of the touch screen can be reduced when the user does not need to carry out touch operation, therefore, the harm of the touch screen to the human health can be reduced under the condition that the normal use of the touch screen is not influenced, and meanwhile, the energy consumption is saved.
specifically, the embodiments of the present application will be further explained below with reference to the drawings.
Example one
Fig. 1 is a flowchart illustrating a driving method of a touch screen according to an embodiment of the present invention, where the driving method can be executed by an intelligent terminal having a touch screen.
specifically, referring to fig. 1, the driving method may include, but is not limited to, the following steps:
110. When the touch signal is received, the touch screen is driven by the first driving voltage V1 for the touch signal detection within a preset time period.
in this embodiment, the "touch signal" refers to a touch signal generated when a user performs a touch operation on a touch screen of the smart terminal, and the touch signal may be detected by the touch screen of the smart terminal. Specifically, when a user touches the touch screen, the touch screen detects a position where a voltage difference is generated, and feeds back position information of the generated voltage difference to the intelligent terminal, where the position information of the generated voltage difference is the "touch signal".
in this embodiment, the "preset time period" may be any time period, for example, it may be 1 second, 5 seconds, 10 seconds, or 1 minute, and the time period may be set by a technical developer, or may be personalized and adjusted by a user according to a personal requirement, or may be adjusted by an intelligent terminal according to an actual application scenario of the intelligent terminal, which is not specifically limited in this embodiment of the present invention. It should be noted that the starting time node of the "preset time period" is the time when the intelligent terminal receives the touch signal most recently. For example, if the preset time period is 5 seconds, if the intelligent terminal receives a touch signal at 10:00:00, the "preset time period" is 10:00: 00-10: 00: 05; if the intelligent terminal receives a touch signal again at 10:00:03, the preset time period is 10:00: 03-10: 00: 08.
In practical applications, the touch screen has a fixed working voltage range, and when the touch screen is driven by a voltage value outside the working voltage range, the touch screen may be damaged or the touch signal detection may not be performed. In this embodiment, the operating voltage range of the touch panel is represented by [ Vlow, Vhigh ], where Vlow represents the minimum driving voltage value and Vhigh represents the maximum driving voltage value. In order to ensure that the touch screen can normally operate, the "first driving voltage V1" in this embodiment is any one of voltage values greater than Vlow and less than or equal to Vhigh, that is, Vlow < V1 ≦ Vhigh.
in this embodiment, when the intelligent terminal is in a used state (that is, when the intelligent terminal is not powered off or locked), any one voltage value of [ Vlow, Vhigh ] may be used to drive the touch screen for touch signal detection, and when the intelligent terminal receives the touch signal, the touch screen is driven by the first driving voltage V1 for touch signal detection within a preset time period. That is, if the smart terminal receives a touch signal (where the touch signal may be a touch signal detected when the touch screen is driven by any one of [ Vlow, Vhigh ] driving voltages to detect the touch signal) at a certain time, the driving voltage of the touch screen is adjusted to the first driving voltage V1 when the touch signal is received, and the touch screen is driven by the first driving voltage V1 for detecting the touch signal within a preset time period from the time when the touch signal is received.
120. And judging whether the next touch signal is received within the preset time period.
in this embodiment, a preset time period is used as a boundary for determining whether a user has an intention to continue a touch operation, if a next touch signal is received within the preset time period, it is determined that the user currently needs to frequently perform the touch operation, and if the next touch signal is not received within the preset time period, it is determined that the user may not need to perform the touch operation on the touch screen within the current time period.
Research shows that, in the working voltage range of the touch screen, the larger the driving voltage of the touch screen is, the stronger the anti-interference capability of the touch screen during touch detection is, and the better the touch experience of a user is, but at the same time, the greater the intensity of electromagnetic radiation generated by the touch screen is, that is, the greater the harm to human health is. The anti-interference capability refers to the capability of the touch screen to accurately detect a touch signal in an environment with large electromagnetic interference, when the touch screen is driven by a large voltage, a large voltage difference can be generated at a touch point when a user touches the touch screen, and even if interference of an external electromagnetic field exists, the touch screen can still accurately transmit the touch signal to a processor of the intelligent terminal.
therefore, in order to ensure that the user can obtain a better touch experience when performing the touch operation, in this embodiment, the touch screen is driven by a larger driving voltage (i.e., the first driving voltage) for performing the touch signal detection in a time period (i.e., a preset time period) in which the user may need to frequently perform the touch operation, and if the next touch signal is received in the preset time period, the step 110 is returned to. Among them, in order to enable the user to obtain the best touch experience when performing a touch operation, the first driving voltage V1 may be set to the maximum driving voltage of the touch screen, that is, V1 ═ Vhigh. If the next touch signal is not received within the preset time period, it indicates that the user may not need to perform the touch operation within the latest time period, for example, the user is watching a video or reading a novel, and at this time, the following step 130 may be performed.
130. And driving the touch screen to detect the touch signal by using a second driving voltage V2.
In this embodiment, if the intelligent terminal does not receive the next touch signal within the preset time period, it indicates that the user may not need to perform the touch operation in the recent time period, and at this time, the driving voltage of the touch screen may be reduced to reduce the electromagnetic radiation generated by the touch screen, thereby reducing the harm of the intelligent terminal to the human health. Therefore, in the present embodiment, Vlow ≦ V2 < V1 ≦ Vhigh. And, preferably, in order to reduce the harm of electromagnetic radiation generated by the touch screen to human health to the maximum extent, the second driving voltage V2 may be set to be the minimum driving voltage of the touch screen, that is, V2 ═ Vlow.
Further, if the touch screen detects that there is a touch signal and sends the touch signal to the processing unit of the intelligent terminal at a certain time in the process of driving the touch screen to detect the touch signal with the second driving voltage V2 (i.e., the intelligent terminal receives the next touch signal), the process returns to the step 110.
According to the technical scheme, the embodiment of the invention has the beneficial effects that: the touch signal detection is carried out by driving the touch screen with the first driving voltage V1 within the preset time period after the touch signal is received, if the next touch signal is not received within the preset time period, the user does not need to use the touch screen at the moment, and the touch screen is driven with the second driving voltage V2 smaller than the first driving voltage V1 to carry out the touch signal detection, so that the electromagnetic radiation intensity of the touch screen can be reduced when the user does not need to carry out touch operation, the harm of the touch screen to the human health can be reduced under the condition that the normal use of the touch screen is not influenced, and meanwhile, the energy consumption is saved.
Example two
Further, in order to improve the user experience of the user when using the touch screen, the second embodiment of the present invention further provides another driving method for the touch screen. The difference between the present embodiment and the first embodiment is: in this embodiment, a time period for driving the touch screen with the second driving voltage V2 for touch signal detection is further determined, and when the time period is reached or exceeded for driving the touch screen with the second driving voltage V2 for touch signal detection, the touch screen is driven with the third driving voltage V3 greater than the second driving voltage V2 for touch signal detection. That is to say, in this embodiment, the time when the user performs the touch operation next time is also predicted, and the driving voltage of the touch screen is adjusted up according to the predicted time, so that the intelligent terminal can make corresponding feedback in time according to the touch operation of the user.
specifically, referring to fig. 2, the driving method includes, but is not limited to, the following steps:
210. When the touch signal is received, the touch screen is driven by the first driving voltage V1 for the touch signal detection within a preset time period.
220. And judging whether the next touch signal is received within the preset time period.
In this embodiment, if the next touch signal is received within the preset time period, the step 210 is returned to when the next touch signal is received; if the next touch signal is not received within the preset time period, the following steps 230 and 240 are performed simultaneously.
230. And driving the touch screen to detect the touch signal by using a second driving voltage V2.
In this embodiment, steps 210, 220 and 230 have the same or similar technical features as steps 110, 120 and 130 in the first embodiment, and the detailed implementation of the steps can refer to the description of the corresponding steps in the first embodiment, and detailed description thereof is omitted in this embodiment.
240. and determining the duration of the touch signal detection when the touch screen is driven by the second driving voltage V2.
In this embodiment, the "duration of driving the touch screen to perform the touch signal detection by the second driving voltage V2" refers to the longest time of driving the touch screen to perform the touch signal detection by the second driving voltage V2, where the duration is a predicted value of the time of the next touch operation performed by the user, and when the duration is reached or exceeded, the user may perform the touch operation.
The duration may be a fixed value, which is pre-configured on the smart terminal by a technical developer, and may be, for example, 30 seconds, 5 minutes, 10 minutes, or 30 minutes. Alternatively, in some embodiments, in order to improve the intelligence of the intelligent terminal, the duration may also be determined according to the content currently processed by the intelligent terminal.
The method specifically comprises the following steps: firstly, acquiring the content currently processed by the intelligent terminal; then, the duration of driving the touch screen to detect the touch signal by the second driving voltage V2 is determined according to the content. The content may be any data that can be processed by the intelligent terminal, and may include but is not limited to: video content, music content, text, novel content, and the like. For example, if the user is currently watching a video, the video that the user is watching is the video content currently processed by the intelligent terminal. The duration of driving the touch screen to detect the touch signal by the second driving voltage V2 is actually determined according to the content, and the time of the next touch operation performed by the user is pre-determined according to the content currently processed by the intelligent terminal, so that when the user performs the touch operation, the intelligent terminal can timely give feedback to the touch operation of the user even in an environment with large electromagnetic interference, and the touch experience of the user is guaranteed.
for example, when the content currently processed by the intelligent terminal is a video content, the specific implementation of determining, according to the content, the duration for driving the touch screen to detect the touch signal by using the second driving voltage V2 may be: acquiring the residual duration of the video content; and taking the remaining time length as the time length for driving the touch screen to detect the touch signal by using the second driving voltage V2. For example, when the user is currently watching a certain video content (that is, the intelligent terminal is currently in a certain video content), the intelligent terminal does not detect a touch signal within a preset time period, for example, within 30 seconds, at this time, the intelligent terminal drives the touch screen with the second driving voltage V2 to perform touch signal detection, and meanwhile, obtains the remaining time of the video content, for example, the remaining time of the video is 5 minutes, it may be determined that the duration of driving the touch screen with the second driving voltage V2 to perform touch signal detection is 5 minutes.
for another example, when the content currently processed by the intelligent terminal is novel content, the specific implementation of determining, according to the content, the duration for driving the touch screen to perform the touch signal detection by using the second driving voltage V2 may be: acquiring the frequency of receiving a touch signal when the story content is processed historically; and determining the duration of the touch signal detection by driving the touch screen with the second driving voltage V2 according to the frequency. For example, after statistics of the historical data, it is found that when a user watches a novel before, the user generally clicks the touch screen once every 20 seconds to turn pages (that is, the frequency of receiving the touch signal when the intelligent terminal processes the novel content historically is every 20 seconds/time), and when the content currently processed by the intelligent terminal is obtained as the novel content, the sum of the frequency of receiving the touch signal when the novel content is processed historically, that is, a preset time period (assumed to be 5 seconds), and the duration of driving the touch screen by the second driving voltage V2 to perform touch signal detection may be determined, so that the duration of driving the touch screen by the second driving voltage V2 to perform touch signal detection may be determined to be 15 seconds.
250. and judging whether the time for driving the touch screen to detect the touch signal by the second driving voltage V2 reaches or exceeds the time length.
in this embodiment, if the smart terminal receives the next touch signal during the touch signal detection period when the touch screen is driven by the second driving voltage V2, the process returns to step 210; if the time for driving the touch screen to perform touch signal detection by using the second driving voltage V2 does not reach or exceed the duration determined in step 240, and the smart terminal does not receive the next touch signal, continuing to perform step 230; if the time for driving the touch screen to perform touch signal detection with the second driving voltage V2 reaches or exceeds the time duration determined in step 240, the following step 260 is performed.
260. And driving the touch screen to detect a touch signal by using a third driving voltage V3.
When the time for driving the touch screen to perform the touch signal detection by the second driving voltage V2 reaches or exceeds the time duration determined in step 240, it indicates that the user may perform the touch operation in the next time, and therefore, in order to ensure the touch experience of the user, in this embodiment, when the time for driving the touch screen to perform the touch signal detection by the second driving voltage V2 reaches or exceeds the time duration, the driving voltage of the touch screen is adjusted in advance (i.e., the touch screen is driven by the third driving voltage V3 to perform the touch signal detection), so as to prepare for performing the touch signal detection with better interference resistance.
