Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terminal according to the present invention may include a handheld device, a vehicle mounted device, a wearable device, a computing device or other processing device connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Station (MS), terminal device (Terminal Equipment), etc. For convenience of description, the present invention is simply referred to as a terminal.
The infrared touch layer detects and locates the touch of the user by using infrared wire nets densely distributed in the X-axis and Y-axis directions. The infrared touch layer is characterized in that a circuit board outer frame is arranged around an LCD (liquid crystal display), infrared transmitting tubes and infrared receiving tubes are arranged on four sides of the circuit board outer frame, infrared rays emitted by the infrared transmitting tubes are received by opposite side infrared receiving tubes, and therefore a plurality of infrared rays are mutually intersected to correspondingly form an infrared wire network.
The infrared pair tubes are respectively arranged on the left side, the right side, the upper side and the lower side of the outer frame of the circuit board, as shown in fig. 1, wherein a plurality of infrared emission tubes are arranged on the left side and the upper side, and a plurality of infrared receiving tubes are symmetrically arranged on the right side and the lower side. The infrared rays emitted by each infrared emitting tube are received by at least one infrared receiving tube, and the infrared rays form a crossed infrared wire network in a touch detection area on the surface of the LCD.
In addition, the infrared pair of tubes of the infrared touch layer shown in fig. 1 may be arranged in such a way that each side is provided with both an infrared emitting tube and an infrared receiving tube, and the infrared pair of tubes may be arranged in such a way that the infrared rays emitted by each infrared emitting tube are received by at least one infrared receiving tube, and each infrared ray forms a crossed infrared wire network in the touch detection area on the surface of the LCD.
Besides the infrared touch layer structure shown in fig. 1, the circuit board outer frame can be arranged on the upper side, the lower side or the left side and the right side of the surface of the LCD, as shown in fig. 2, N infrared emitting tubes are uniformly arranged on the upper side, the lower side or the left side and the right side, an infrared receiving tube is arranged between 2 infrared emitting tubes at intervals of 3 infrared emitting tubes, infrared light emitted by each infrared emitting tube is received by at least one infrared receiving tube, and the infrared light emitted and received by each infrared emitting tube forms a crossed infrared network in a touch detection area, and N is a positive integer.
The principle adopted by the infrared touch layer is that when a user touches the screen, the finger can block two infrared rays passing through the position, as shown in fig. 3, when the user touches and presses the touch screen, the touch upper surface is slightly deformed, and the transmission of infrared rays is blocked, so that the infrared ray sent by the generating tube cannot be received by the infrared receiving tube. It should be noted that any object touching the screen can change the infrared ray on the contact, so the screen with the infrared touch layer has the advantage of not being interfered by current, voltage and static electricity, and is suitable for severe environmental conditions.
Based on the above-mentioned structure of the infrared touch display screen, the embodiment of the invention provides a flow diagram of a touch method of a terminal with a pressure sensing layer, as shown in fig. 4, and the specific implementation method includes:
step S101, obtaining a detection result of an infrared wire network on an infrared touch layer of a terminal, wherein the infrared wire network is formed by transmitting infrared rays to an infrared receiving tube by an infrared transmitting tube on the infrared touch layer, and the terminal at least comprises the infrared touch layer and a pressure sensing layer formed by a pressure sensor.
Step S102, determining the coordinate center of the touch area of the user according to the detection result.
Step S103, adjusting the state of the pressure sensor in the target area including the coordinate center from the off state to the on state.
As shown in fig. 5, the upper layer of the screen of the terminal is an infrared touch layer, and infrared pair tubes are arranged in the transverse and longitudinal directions of the infrared touch layer, wherein each infrared pair tube consists of an infrared transmitting tube and an infrared receiving tube, and infrared rays emitted by one infrared transmitting tube are received by the opposite infrared receiving tube. Thus, an infrared wire mesh is formed on the surface of the infrared touch layer. And a pressure sensing layer is symmetrically arranged below the infrared touch layer, wherein the pressure sensing layer is provided with pressure sensors in the transverse and longitudinal directions, each row and each column of pressure sensors are connected with a row CS signal and a column CS signal, and the pressure sensors are arranged in the cross connection of the rows and the columns. By utilizing the principle of the infrared touch layer, when a user touches the screen, part of infrared rays are blocked, as shown in fig. 5, and the processor determines the coordinate positions (X, Y) when the finger touches the touch screen according to the coordinates of the infrared receiving tube and the infrared emitting tube corresponding to the blocked infrared rays in the detection result. At this time, a circular region is drawn with a certain radius value r (r > thumb width) centered on the touch center coordinates (X, Y). The processor turns on the pressure sensors in the circular area while the pressure sensors in the other areas remain off by default.
The stacked structure of the screen with the terminal of the pressure sensing layer is mainly characterized in that a layer of pressure sensing layer is additionally arranged below the infrared touch layer, and a plurality of pressure sensors are arranged on the pressure sensing layer and are used for collecting pressure values when a user presses the screen. For example, fig. 6 shows a stacked structure of a screen of a terminal currently provided with a pressure sensing layer, mainly a circuit board outer Frame with infrared pair tubes, a Force Sensor layer, an LCD (Liquid Crystal Display) layer, a Metal Frame (substrate) layer, from top to bottom. As can be seen from the figure, the LCD layer and Force Sensor layer in the stacked structure are arranged symmetrically up and down, so the target area in step S103 is on the Force Sensor layer, and the area where the user touches the LCD layer is projected down to the Force Sensor layer is generally the target area.
In addition, as shown in fig. 7, the pressure sensors on the pressure sensing layer are arranged in a matrix form, and as can be seen from fig. 7, each row shares a row CS (chip select) signal, and then each column shares a column CS signal. A processor determines a row number and a column number of the pressure sensor array within a target area containing the coordinate center; and setting a row chip selection signal of the pressure sensor corresponding to the row number as a first level, and setting a column chip selection signal of the pressure sensor corresponding to the column number as a second level, so that the state of the pressure sensor in the target area is adjusted from a default closed state to an open state, wherein the first level is unequal to the second level. That is, the processor determines a corresponding target area on the pressure sensing layer according to the user touch signal acquired by the touch screen, and then outputs a control signal corresponding to the target area to the pressure sensing screen to drive, and then outputs a pressure sensor of a corresponding area selected by the line CS signal, so that the pressure sensor works normally, as shown in fig. 8. At the moment, the selected sensor is driven to acquire pressure data once, and finally the acquired data is sent to the processor through the data transmission bus. The processor receives the relevant pressure data and then performs the corresponding operation. For example, in the matrix corresponding to the target area, the signals CS1 and CS2, and the columns CS3 and CS4 are input by the processor to the signals CS1 and CS2, and the signals CS3 and CS4 are input to the column at a high level, so that the pressure sensors directly crossing the signals CS1 and CS2, and the columns CS3 and CS4 are turned on, thereby realizing the adjustment of the pressure sensors from the off state to the on state.
When the pressure sensor is started, the processor acquires a pressing pressure value acquired by the pressure sensor and generates an execution result related to the touch area and the pressing pressure value. Specifically, the pressure sensor starts to collect the pressure value accumulated in the touch duration of the user, the processor acquires the pressure value, and then the processor processes the pressure value correspondingly according to the statistics result of the pressure value. For example, the user is currently reading an electronic document, and the user presses any position in the screen for a certain period of time due to the small font, after the touch screen of the terminal transmits a touch signal to the processor, the processor calculates a touch area of the user, and opens a pressure sensor corresponding to the touch area, and the processing speed of the processor is in millisecond level, so that the touch area is almost equal to the touch area of the user, and the pressure sensor is opened. Further, the pressure sensor collects the pressing pressure of the user, then judges whether the accumulated pressure value exceeds a set threshold value, and if so, enlarges the font of the document. Therefore, by the method, the pressure sensor can be set to be in the off state by default at first, and then the pressure sensor of the corresponding area is opened dynamically according to the touch condition of the user, so that the power consumption is effectively reduced.
Further, the state of the pressure sensor in the target area including the coordinate center may also be adjusted from the on state to the off state. That is, when the processor of the terminal responds to the pressing action of the user, the pressure sensor of the punch card is restored to the default off state immediately, which is to further reduce the power consumption.
In addition, if the processor acquires a standby signal generated by triggering a standby key by a user, each pressure sensor on the pressure sensing layer of the terminal is adjusted to be in a closed state. For example, after the user presses the POWER key of the terminal after the use, the backlight is turned off immediately, and meanwhile, the embodiment of the invention further adjusts all the turned-on pressure sensors to be in a turned-off state, so as to avoid the waste of POWER consumption caused by the fact that the pressure sensors are in the turned-on state when the terminal is dormant.
Based on the same technical concept, the embodiment of the invention also provides a touch device, which can execute the method embodiment. The device provided by the embodiment of the invention is shown in fig. 9, and comprises: an acquisition unit 401, a determination unit 402, an adjustment unit 403, wherein:
