The control method provided by the embodiment of the present application is explained by a specific scenario in the embodiment of the present application.
In the related art, a power supply circuit of a Touch screen adopting a Touch and Display Driver Integration (TDDI) scheme adopts a power supply circuit including a voltage boosting circuit.
The boost circuit will convert to 3 voltages, including: a Positive power supply Voltage (VSP) of +5.5V, a Negative power supply Voltage (VSN) of 5.5V, and an interface Voltage (Input/Output Collector Voltage, IOVCC) of 1.8V; here, the relationship of voltage, current, and power consumption of VSP, VSN, and IOVCC is shown in table 1.
TABLE 1 Voltage, Current, and Power consumption relationship for VSP, VSN, and IOVCC
Item VSP VSN IOVCC
Voltage (volt) +5.5 -5.5 +1.8
Current (milliampere) 1.25 0.25 3.02
Power consumption (milliwatt) 6.875 1.375 5.436
Under the condition that the electronic equipment adopting the TDDI scheme is in a standby mode and scans a touch sensor on a touch screen of the electronic equipment, the power consumption of the electronic equipment adopting the TDDI scheme is larger than that of the electronic equipment not adopting the TDDI scheme and is also larger than that of the electronic equipment adopting a voltage stabilizing circuit for supplying power. Fig. 5 is a graph showing power efficiency versus output current, wherein the X-coordinate represents the output current and the Y-coordinate represents the power efficiency. The power efficiency of an electronic device powered with a voltage regulator circuit is characterized by 51, the power efficiency of an electronic device not employing the TDDI scheme is characterized by 52, and the power efficiency of an electronic device employing the TDDI scheme is characterized by 53.
Here, the reasons why the power consumption of the electronic device adopting the TDDI scheme increases include:
1) the electronic equipment adopting the TDDI scheme needs 2 touch chips when the WU is high in resolution, needs 1 touch chip when the WX is low in resolution, and needs 1 touch chip when both the WU and the WX are powered by the scheme including the voltage stabilizing circuit.
2) The power supply circuit of the touch screen of the electronic equipment adopting the TDDI scheme comprises the following steps: the device comprises a power supply, a boost circuit, a touch chip and a touch screen; among them, the boost circuit needs to convert into 3 voltages of VSP, VSN and IOVCC, and the power consumption of these 3 voltages is large.
The power supply circuit of the touch screen of the electronic equipment powered by the voltage stabilizing circuit is as follows: the touch control circuit comprises a power supply, a voltage-stabilizing LDO circuit, a touch control chip and a touch control screen, wherein the LDO circuit only needs to be converted into power supply VDD voltage, and the power consumption is low.
The boost circuit of the electronic device adopting the TDDI scheme has low efficiency under the condition of low load, increases power consumption and has the power conversion efficiency of 50%.
According to the embodiment of the application, when the electronic equipment is in a standby mode, an original TDDI framework is changed, a VSP or VSN framework is not used, and a power supply is directly connected with a touch screen; or the LDO circuit power supply scheme is adopted, the problem of low load efficiency of the boost circuit is optimized, the power efficiency can be improved from 50% to 90%, and the power consumption is reduced.
Further, when the electronic device is in a standby mode and scans a touch sensor on a touch screen of the electronic device, the existing technical scheme is as follows: the touch sensors (1, 1) and (1, 2) are scanned through the touch chip A, the touch sensors (1, 3) and (1, 4) are scanned through the touch chip B, the touch sensors (2, 1) and (2, 2) are scanned through the touch chip A, and the touch sensors (2, 3) and (2, 4) are scanned through the touch chip B until the scanning of the touch sensors on the touch screen is completed.
As shown in fig. 6, the scanning scheme of the embodiment of the present application is: the touch screen 60 of the electronic device is divided into a first area 61 and a second area 62, wherein the first area 61 corresponds to a first touch chip 63, and the second area 62 corresponds to a second touch chip 64. The touch sensors in the first area 61 are scanned by the first touch chip 63, and the touch sensors in the second area 62 are scanned by the second touch chip 64, wherein the scanning time sequence is as follows: scanning touch sensors with coordinates of (1, 1), (1, 2), (2, 1) and (2, 2) through a first touch chip 63, and scanning touch sensors with coordinates of (1, 3), (1, 4), (2, 3) and (2, 4) through a second touch chip 64; ..., the touch sensors of coordinates (6, 1), (6, 2), (7, 1), (7, 2) are scanned by the first touch chip 63, and the touch sensors of coordinates (6, 3), (6, 4), (7, 3), (7, 4) are scanned by the second touch chip 64.
According to the embodiment of the application, when the electronic equipment is in a standby mode, an original TDDI framework is changed, a VSP or VSN framework is not used, and a power supply is directly connected with a touch screen; or the problem of low load efficiency of the boost circuit is optimized by adopting the LDO circuit power supply scheme, so that the power supply efficiency is improved; meanwhile, the touch sensor is scanned by the touch chip in a left-right cross scanning mode, so that the power consumption is reduced.
The embodiment of the application also provides a control device, and each module included in the control device and each unit included in each module can be realized by a processor of the control device; of course, the implementation can also be realized through a specific logic circuit; in implementation, the processor may be a Central Processing Unit (CPU), a Microprocessor (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.
As shown in fig. 7, the control device 70 includes:
the control module 701 is configured to control a power supply circuit of the touch screen to switch from a first path to a second path if it is detected that the electronic device enters a standby mode from a working mode; wherein the power consumption of the second path is less than the power consumption of the first path; the second path includes: the power supply is directly connected with a channel of the touch screen or comprises a power supply channel of the voltage stabilizing circuit;
