Low-power consumption touch display module, touch electronic device with same and software system thereof

Abstract

The invention relates to a low-power consumption touch display module, a touch electronic device with the same and a software system thereof. An MCU (microprogrammed control unit) is arranged in a touch display module and used for running a sub-system; a CPU (central processing unit) of a host is used for running a main system; in a standby state, the host gives the display control right to the MCU, the CPU of the host mainly keeps the detection on the functions of the network and communication part, the MCU enters a standby state, and the standby information and the application selection are both realized by the MCU directly driving a display screen; and once a specific application (such as making a call, browsing a webpage and the like) is selected, the display drive control right is handed over to the CPU, and the CPU of the host stays in a sleep state in the standby state, thus more energy is saved, the standby information can be displayed, and simple touch operation can be performed.

Description

technical field [0001] The invention relates to the fields of displays and touch screens, in particular to a low-power consumption touch display module, a touch electronic device with the module and a software system thereof. Background technique [0002] The projected capacitive touch screen has many advantages such as high transparency, no need to apply force when touching, and can resist harsh external environments. Control display components have been applied in portable smart electronic products such as mobile phones, tablet computers, and notebook computers. [0003] At present, the structure of such intelligent electronic products is generally as follows figure 1 As shown, among them, the central processing unit (CPU) is not only used to process various application programs, but also directly used to control equipment including communication systems, audio systems, various sensors, display screens, touch screens, etc. Therefore, even if there is no When the program ...

AI Technical Summary

Problems solved by technology

[0003] At present, the structure of such intelligent electronic products is generally as follows figure 1 As shown, the central processing unit (CPU) is not only used to process various application programs, but also directly used to control equipment including communication systems, audio systems, various sensors, display screens, touch screens, etc. Therefore, even if there is no When the program is running, in order to maintain the operation of various sensors, the CPU also needs to work continuously. Generally speaking, the continuous work of the CPU will lead to an increase in power consumption, which makes the battery life of this portable smart electronic product insufficient.

[0004] In addition, since the display screen is directly controlled by the CPU, its output screen also needs to be generated by the operation of the CPU. Therefore, in order to reduce the power consumption of the CPU, when this electronic product is in standby, its display screen is generally It is in the closed state and cannot display images such as time and weather in real time. Users need to wake up the device by pressing the button to turn on the display, which is generally inconvenient

[0005] The same is true for the touch screen. In the standby state, the touch screen is generally turned off, and the user cannot wake up the device through the touch screen or cooperate with the display to perform some simple operations.

It will also bring some inconvenience to the operation
