In addition, after the user changes the display screen subassembly or changes other operations that need carry out touch display screen calibration according to the demand, need recalibrate touch display screen after the change, complex operation.
The replacing method and the electronic device 100 according to the embodiment of the invention are described in detail below with reference to fig. 1 to 9.
The electronic device 10 may be a mobile phone, a tablet computer, a laptop computer, a game machine, a head-up display device, etc. The electronic device according to the embodiment of the present invention is described by taking a mobile phone as an example, and it is understood that the specific form of the electronic device may be other, and is not limited herein.
Referring to fig. 1 to 3, an embodiment of the invention provides a replacing method for an electronic device 100. The electronic device 100 comprises a touch display screen module 11 to be replaced, and the replacing method comprises the following steps:
s10: providing a standby touch display screen module 10, wherein the standby touch display screen module 10 comprises a standby frame 102 and a standby touch display screen 101 fixedly connected with the standby frame 102, and the standby touch display screen 101 completes the capacitance calibration of a touch point after being fixedly connected with the standby frame 102;
s20: and disassembling the touch display screen module 11 to be replaced. And
s30: the standby touch display screen module 10 is mounted to the electronic device 100 to replace the touch display screen module 11 to be replaced.
In the replacement method according to the embodiment of the present invention, after the standby touch display screen 101 is mounted to the standby touch display screen module 10, the capacitance value of the standby touch display screen 101 is calibrated, so that the influence of the standby frame 102 on the capacitance value of the standby touch display screen 101 is reduced, and the calibration data is recorded in the standby touch display screen module 10, so that the whole standby touch display screen module 10 is calibrated to the standby touch display screen 101 when leaving a factory. In addition, in the using process, when a user needs to replace the touch display screen module in the electronic device 100, the standby touch display screen module 10 with the calibrated capacitance value can be directly used to replace the touch display screen module 11 to be replaced. Therefore, the capacitance value of the standby touch display screen 101 does not need to be calibrated again after the standby touch display screen module 10 is replaced, and the operation is convenient.
Referring to fig. 3 and 4, in some embodiments, the step S10 of providing a standby touch display module 10 includes:
s111: a standby touch screen display 101 is provided.
S121: and providing a standby middle frame 102, and connecting the standby touch display screen 101 and the standby middle frame 102 in a pressing mode. And
s131: after the standby touch display screen 101 is in press-fit connection with the standby middle frame 102, capacitance calibration is performed on the touch points of the standby touch display screen 10.
Specifically, after the standby touch display screen 101 is in press-fit connection with the standby middle frame 102, capacitance values of touch points of a portion, pressed with the standby middle frame 102, of the standby touch display screen 101 may change, and in order to reduce the influence of the standby middle frame 102 on the standby touch display screen 101, capacitance value calibration needs to be performed on the touch points of the standby touch display screen 101. The spare housing 102 may be a spare middle housing 102.
Referring to fig. 5, in some embodiments, the step S131 of calibrating the capacitance value of the touch point of the standby touch screen 101 after the standby touch screen 101 is press-connected to the standby middle frame 102 includes:
s1311: and detecting the capacitance value of the touch point after the standby touch display screen 101 and the standby middle frame 102 are connected in a pressing mode to be used as a reference capacitance value so as to finish calibration.
Specifically, the capacitance value of the touch point after the standby touch display screen 101 and the standby middle frame 102 are connected in a pressing manner may be directly set as the reference capacitance value. For example, the initial capacitance value of each touch point of the standby touch screen 101 before the standby touch screen 101 is press-connected to the standby middle frame 102 is 1 Picofarads (pF), and when the change of the capacitance value reaches 10pF, the standby touch screen 101 transmits the data of the change of the touch point to the processor to execute a corresponding instruction or more. After standby touch screen 101 is connected with standby center 102 pressfitting, the capacitance value of the touch point of (x1, y1) department in standby touch screen 101 becomes 6pF (increases 5pF than initial capacitance value), the capacitance value of other touch points is 1pF (increases 0pF than initial capacitance value), at this moment, the benchmark capacitance value of the touch point of (x1, y1) department sets up to 6pF, the benchmark capacitance value of other touch points all sets up to 1 pF. That is, when the change of the capacitance value of the touch point at (x1, y1) in the standby touch screen 101 reaches 15pF (15pF is 10pF +5pF) or more, the standby touch screen 101 transmits the data of the touch point change to the processor to execute the corresponding instruction. When the capacitance value of the touch points other than the touch point at (x1, y1) in the standby touch screen 101 changes by more than 10pF (10 pF-10 pF +0pF), the standby touch screen 101 transmits the data of the touch point change to the processor to execute a corresponding instruction.
It can be understood that the calibration method may also be to readjust the touch points of the standby touch display screen 101, which generate the capacitance value change after being pressed and connected to the standby middle frame 102, to the initial values. For example, when the change of the capacitance value reaches 10pF or more, the standby touch screen 101 transmits the data of the touch point change to the processor to execute the corresponding instruction. The initial capacitance value of each touch point of the standby touch display screen 101 before the standby touch display screen is connected with the standby middle frame 102 in a pressing manner is 1 Picofarads (pF); after the standby touch screen 101 is connected to the standby middle frame 102 in a pressing manner, the capacitance value of the touch point at (x2, y2) in the standby touch screen 101 becomes 4pF, and the capacitance values of other touch points are all 1 pF. At this time, the capacitance value of the touch point at (x2, y2) is calibrated to an initial value, that is, the capacitance value of the touch point at (x2, y2) after calibration is 1 pF. That is, when the change of the capacitance value of the touch point at (x2, y2) in the standby touch screen 101 reaches 10pF or more, the standby touch screen 101 transmits the data of the touch point change to the processor to execute the corresponding instruction.
It should be noted that the data of these capacitance values are merely exemplary, and the embodiments of the present invention are not limited thereto.
Referring to fig. 6, in some embodiments, the step S10 of providing a standby touch screen 101 module includes:
s112: a standby touch screen display 101 is provided.
S122: the capacitance value of the touch point of the standby touch display screen 101 is detected as a first reference capacitance value.
S132: a spare middle frame 102 is provided, and the spare touch display screen 101 is fixedly connected with the spare middle frame 102. And
s142: detecting a capacitance value of a touch point of the standby touch display screen 101 after the standby touch display screen is fixedly connected with the standby middle frame 102 as a second reference capacitance value;
s152: and calibrating the standby touch display screen 101 according to the first reference capacitance value and the second reference capacitance value.
Specifically, for example, the capacitance value of each touch point of the standby touch screen 101 is 1pF, that is, the capacitance value of each touch point is 1pF as the first reference capacitance value. After the standby touch screen 101 is connected to the standby middle frame 102 in a pressing manner, the capacitance value of the touch point at (x3, y3) in the standby touch screen 101 becomes 3pF (increased by 2pF compared with the initial capacitance value), the capacitance value of the touch point at (x4, y4) becomes 5pF (increased by 4pF compared with the initial capacitance value), the capacitance values of the other touch points are all 1pF, that is, the capacitance value of the touch point at (x3, y3) is 3pF, (x4, y4) is 5pF, and the capacitance values of the other touch points are all 1pF as the second reference capacitance value. The standby touch display screen 101 can be calibrated according to the first reference capacitance value and the second reference capacitance value, and thus, the influence of the standby middle frame 102 on the capacitance value of the standby touch display screen 101 is favorably reduced. It should be noted that the data of these capacitance values are merely exemplary, and the embodiments of the present invention are not limited thereto.
Referring to fig. 7, in some embodiments, the step S152 of calibrating the standby touch screen 101 according to the first reference capacitance value and the second reference capacitance value includes:
s1521: and judging whether the first reference capacitance value and the second reference capacitance value are equal or not.
S1522: when the first reference capacitance value is equal to the second reference capacitance value, the standby touch display screen 101 is calibrated by using the first reference capacitance value or the second reference capacitance as the reference capacitance value. And
s1523: and when the first reference capacitance value is not equal to the second reference capacitance value, calibrating the capacitance value of the touch point with the changed capacitance value.
Specifically, the capacitance values of the touch points before and after the standby touch display screen 101 and the standby middle frame 102 are connected in a press fit manner are equal, and a first reference capacitance value detected before the standby touch display screen 101 and the standby middle frame 102 are connected in the press fit manner or a second reference capacitance value detected after the standby touch display screen 101 and the standby middle frame 102 are connected in the press fit manner can be directly used as the reference capacitance value of the standby touch display screen 101. When the first reference capacitance value is not equal to the second reference capacitance value, the capacitance value of the touch point with the changed capacitance value is calibrated, for example, the capacitance value of the touch point with the changed capacitance value can be set as the reference capacitance value, and touch detection is performed on the reference capacitance value, while the reference capacitance values of other touch points without the changed capacitance value remain unchanged. That is, when the change of the capacitance value reaches 10pF or more, the standby touch screen 101 transmits the data of the touch point change to the processor to execute the corresponding instruction. When the capacitance value of the touch point at (x3, y3) in the standby touch screen 101 changes to be greater than 12pF (12pF is 10pF +2pF), the touch screen transmits the data of the touch point change to the processor to execute a corresponding instruction. When the change of the capacitance value of the touch point other than the touch point at (x4, y4) in the standby touch screen 101 reaches 14pF (14pF is 10pF +4pF) or more, the standby touch screen 101 transmits the data of the touch point change to the processor to execute a corresponding instruction. When the capacitance value of the touch points other than the touch point at (x3, y3) and the touch point at (x4, y4) in the standby touch screen 101 changes by more than 10pF (10pF is 10pF +0pF), the standby touch screen 101 transmits the data of the touch point change to the processor to execute a corresponding command.

Specifically, in the case that only the touch display screen 111 to be replaced in the electronic device 100 needs to be replaced, after the standby touch display screen 101 is replaced with the touch display screen 111 to be replaced, since the capacitance value of the touch point of the standby touch display screen 101 after the standby touch display screen 101 is in press-fit connection with the middle frame 112 to be replaced may change, the capacitance value of the touch point of the standby touch display screen 101 needs to be recalibrated. Or in the case that only the middle frame 112 to be replaced in the electronic device 100 needs to be replaced, after the middle frame 112 to be replaced is replaced by the spare middle frame 102, since the capacitance of the touch point of the touch display screen 111 to be replaced and the touch point of the spare middle frame 102 after press-fit connection may change, the capacitance of the touch point of the touch display screen 111 to be replaced needs to be recalibrated.
