Power saving touch e-book

The present invention relates to an electronic book, and more particularly to a power-saving touch electronic book, which determines whether to activate a touch function according to the distance between a stylus and an electronic book.

According to the convenience, the touch panel has been widely used in portable input electronic devices, such as touch electronic books. In order to reduce the weight, the battery of the general touch e-book is very limited. However, when the user does not make any input, the touch sensing module of the general touch e-book still consumes power, which not only reduces the battery life, but also does not meet the requirements of environmental protection.

In view of this, the present invention proposes a novel touch e-book architecture, which can determine whether to activate the touch function according to the distance between a stylus and an e-book to avoid unnecessary power consumption.

The main purpose of the present invention is to disclose a power-saving touch electronic book, which can detect the distance between a stylus and an e-book by a proximity detecting device to determine whether to activate the touch function to avoid unnecessary power consumption. .

Another object of the present invention is to provide a power-saving touch electronic book, which can determine whether to turn off the touch function by using an idle timing function of a control unit, so as to avoid unnecessary interference before the user touch operation, thereby avoiding unnecessary The power consumption.

To achieve the above objectives, a power-saving touch e-book is proposed, which uses a stylus as an input means. The power-saving touch e-book has a proximity detecting unit, a control unit, and a touch. Screen.

The proximity detecting unit is configured to detect a distance between the stylus and the proximity detecting unit to output a starting signal, and the starting signal exhibits a first potential when the distance is less than or equal to a preset distance. For example, a high potential, when the distance is greater than the preset distance, exhibits a second potential, for example, a low potential.

The control unit has a start input, a touch interface, and a timing unit. The activation input is coupled to the activation signal. The touch mask has a supply power output and a sensing signal input, and the timing unit is configured to perform an idle timing operation. The control unit outputs a sensing supply power through the supply power output terminal when the start signal is changed from the second potential to the first potential, and reads a touch sensing signal through the sensing signal input terminal to receive A touch input. After the control unit detects that the start signal changes from the second potential to the first potential, the timing unit starts counting from zero; during the timing, if the control unit receives the touch input, the timing unit will It is zeroed and then re-timed. When the control unit does not detect that the activation signal changes from the second potential to the first potential and the duration of the non-receiving input reaches an idle time setting value, that is, the timing value of the timing unit reaches the When the idle time setting is set, the control unit cuts off the sensing supply power, wherein the idle time setting has a preset value and can be changed by inputting the touch screen to the touch screen.

The touch screen is coupled to the touch interface to provide the touch sensing signal under the power supply of the sensing power supply and the touch operation of the stylus.

The present invention has the following functions due to its novel design:

1. The e-book of the present invention automatically turns on a touch function when the distance between the stylus and the e-book proximity detecting unit is greater than a predetermined distance, and causes a timing unit to start timing from zero.

2. The e-book of the present invention can be used by the user to input an idle time setting value on the touch screen by using the stylus, wherein the idle time setting value has a preset value.

3. The electronic book of the present invention can turn off the touch function when the user reaches the idle time setting value without the duration of any touch input action.

That is, the design of the present invention can be lifted before interfering with the user's touch operation, thereby avoiding unnecessary power consumption of the touch e-book.

The detailed description of the drawings and the preferred embodiments are set forth in the accompanying drawings.

Please refer to FIG. 1 , which is a block diagram of a preferred embodiment of the power-saving touch electronic book of the present invention. As shown in FIG. 1 , the power-saving touch electronic book 100 has a proximity detecting unit 110 , a control unit 120 , and a touch screen 130 .

The proximity detecting unit 110 is configured to generate a start signal having a first potential and a second potential, for example, a high potential and a low potential, respectively. When a distance between a stylus (not shown in FIG. 1) and the proximity detecting unit 110 is less than or equal to a preset value, the activation signal exhibits the first potential; when the stylus is connected to the proximity When the detection unit 110 is separated by a distance greater than the preset value, the activation signal exhibits the second potential. The proximity detecting unit 110 can be a magnetic sensor, or an ultrasonic sensor, or a capacitive proximity sensor. Since these sensors are well known, their working principles are not intended to be repeated here.

The control unit 120 is coupled to the proximity detecting unit 110 and the touch screen 130, and has a start input terminal, a touch interface, and a timing unit. The control unit 120 receives the activation signal by the activation input. When the control unit 120 detects that the activation signal changes from the second potential to the first potential, the timing unit starts timing from zero, outputs a sensing supply power, and supplies the sensing through the touch interface. The power is coupled to the touch screen 130 and the touch sensing signal sent by the touch screen 130 is read by the touch interface to receive a touch input. During the timing, if the control unit 120 receives the touch input, the timing unit will be first reset to zero and then re-timed. When the control unit 120 does not detect that the start signal has changed from the second potential to the first potential and the time when the touch input is not received reaches an idle time setting value, that is, the timing value of the timing unit reaches the time When the idle time setting value is idle, the control unit 120 cuts off the sensing supply power. The control unit 120 is preferably a microcontroller, and the microcontroller has a register for storing the idle time setting value, wherein the register has a preset value, and the The touch screen 130 is input and changed.

The touch screen 130 has an electronic paper panel and a touch module. The electronic paper panel receives a picture information and displays it on a panel according to an electronic paper input, and the touch module is coupled to the sensing supply power source through the touch interface to obtain a touch sense. The touch sensing signal is sent through the touch interface under the touch operation of the stylus. The electronic paper panel can be, for example, but not limited to, an electrophoretic display, a microelectromechanical display, a cholesteric liquid crystal display, an electrowetting display, or a liquid crystal display, and the electronic paper input port is preferably a universal serial bus (USB) port. The touch module can be, for example, but not limited to, a resistive touch module, a capacitive touch module, an optical touch module, an acoustic wave touch module, or a pressure sensing touch module.

Please refer to FIG. 2 , which is a schematic diagram showing the distance d between the stylus pen 200 of the present invention and the proximity detecting unit 110 of the power-saving touch electronic book 100 .

The power-saving touch electronic book of the present invention has the following three states during operation:

State 1: When the distance between the stylus 200 and the proximity detecting unit 110 is changed from greater than d to less than d, the power-saving touch electronic book immediately enters state one. In this state, the timing unit starts counting from zero, and the sensing supply power is turned on.

State 2: When the user makes a touch input to the touch screen 130 by using the stylus 200, the power-saving touch e-book immediately enters state two. After entering this state, the timing unit will be reset to zero before starting timing, and the sensing supply will remain on. This state 2 continues until the timing value of the timing unit touches an idle time setting value.

State 3: When the timing value of the timing unit touches the idle time setting value, the power-saving touch e-book immediately enters state three. After entering this state, the sensing supply power is cut off to save power consumption.

In summary, the power-saving touch electronic book of the present invention can detect the distance between a stylus and an e-book by a proximity detecting device to determine whether to activate the touch function to avoid unnecessary power consumption. The touch function can be turned off by the idle timing function of a control unit to avoid interference with the normal touch operation of the user. Therefore, the present invention has indeed improved the lack of the conventional touch electronic book.
