Description

Electronic book and its power supply controller and its power supply control method

technical field

The invention relates to an electronic book, in particular to an electronic book, a power controller and a control method thereof.

Background technique

Electronic books have been widely accepted as a reading tool nowadays, and the structures of various electronic components inside are similar, and have long been familiar to technicians in the technical field and even consumers. However, in terms of the convenience of e-books in use, all current products are still insufficient. This convenience problem is reflected in the actual use environment of e-books, which means that when using e-books, users usually use them on public transportation, and of course some use them while waiting for traffic signals while driving. However, the problem often encountered when using e-books on public transport vehicles is that people cannot read when entering, leaving or moving in the compartment. Take it out and continue reading after sitting down, but in the above-mentioned situation, the electric power of the e-book is still running continuously, so it will cause a waste of electric power for a long time. Similarly, when the self-driving car user finishes waiting for the traffic signal and begins to drive forward, he cannot use the e-book. However, the power of the e-book continues to operate at this time, which causes power waste.

In order to solve this problem, some e-books have added a standby function, allowing users to operate the standby function, usually by pressing the standby button, to achieve the standby effect, thereby achieving the purpose of power saving. However, such an operation is still troublesome, because the action of pressing the button is not as intuitive as putting away or placing the e-book, which means that the user needs to press the standby button one more time before putting away or putting down the e-book. In addition to wasting time, it is mainly because the user needs to be distracted to operate because of this extra step, which makes the use of the e-book not smooth enough. If the user has to enter, leave or stay in the compartment When moving and operating the standby function of the e-book, some unexpected situations occur, such as the sudden shaking of the carriage or the actions of other passengers, which will make the user unable to respond immediately, causing some inconvenience, more serious and even for the occurrence of accidental damage.

In addition, there is another kind of e-book whose standby or power-off state is operated through a micro switch. Usually, this e-book is also used with an opening and closing folder, that is, the e-book is set in the opening and closing folder. When the folder is closed, the micro switch is touched to activate the standby or shutdown state. However, this still has some disadvantages. One of the problems is the durability of the micro switch. Since the micro switch operates through mechanical force transmission, there will be problems of mechanical friction and elastic fatigue. If you want to achieve extremely high durability , and high-durability microswitches are usually very expensive, so there is a problem of high cost when using microswitches; another problem is the opening and closing clip itself, because when using this e-book, a special opening and closing clip must be used. It is more effective to touch the micro switch. If a non-special opening and closing clip, protective cover and other similar items are used, the micro switch may not be able to operate when the non-special opening and closing clip is closed, so that the saving cannot be achieved. purpose of electricity.

To sum up, in view of the shortcomings of the existing technology, the applicant invented the "Electronic Book and Its Power Supply Controller and Its Power Supply Control Method" in this case to improve the above-mentioned shortcomings of the existing methods.

Detailed ways

The following describes the various embodiments of the "Electronic Book and Its Power Controller and Its Power Control Method" in this case, please refer to the accompanying drawings, but the actual configuration and adopted methods do not necessarily fully comply with the described content. Those skilled in the art can make various changes and modifications without departing from the actual spirit and scope of the present application.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an embodiment of an electronic book of the present invention. It discloses that the electronic book 1 has a display surface 10 , a character keyboard area 11 , and a function key area 12 . In addition, the electronic book 1 also has a light sensor 13 for sensing the presence or absence of light irradiation. In general use, as shown on the left side of Figure 1, the display surface 10 of the front of the electronic book 1 is facing the user, and when the user turns the display surface 10 of the electronic book 1 downward to the right side of Figure 1 The side shape, that is, the back of the e-book 1 is facing upwards, so that the light sensor 13 is facing downwards, because the light generally comes from the top of the e-book 1 when reading the e-book 1, that is, the light irradiates the front of the e-book 1 The display surface 10, therefore, once the back of the electronic book 1 is turned up, it means that the user does not read the electronic book, and the light cannot irradiate the display surface 10 on the front of the electronic book 1, so the present invention uses light irradiation None to activate the standby or shutdown function. Since the display surface 10 can be irradiated by light when facing upwards, and not when facing downwards, the light sensor 13 is mostly arranged on the front of the electronic book 1, as shown in FIG. 1 , when the user puts the electronic book 1 facing down, On the table (not shown in the figure), or on the assistant's seat (not shown in the figure) next to the driver's seat, the light sensor 13 can no longer be irradiated by light, and the light sensor 13 will start standby or shut down function to save power.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram of an embodiment of the electronic book of the present invention. It discloses that the electronic book 1 has a display surface 10 , a character keyboard area 11 , and a function key area 12 . In addition, the electronic book 1 also has a light sensor 13 for sensing the presence or absence of light irradiation. In general use, as shown on the left side of Figure 2, the display surface 10 of the front of the electronic book 1 is facing the user, because light is generally needed to illuminate the display surface of the electronic book 1 when reading the electronic book 1 10, so there is usually a light source 2 located near the top of the front of the e-book 1 . In addition, usually the light source 2 is a lamp. When the user is not reading the e-book 1, the light source 2 is usually turned off. At this time, as shown on the right side of FIG. 2, the light sensor 13 cannot sense the light irradiation. , immediately start the standby or shutdown function, in order to achieve the power saving effect.

Please refer to FIG. 3a and FIG. 3b . FIG. 3a and FIG. 3b are schematic diagrams of other embodiments of the electronic book of the present invention. Figure 3a reveals that the electronic book 1 of the present invention is placed in a container 3, usually a protective cover or a paper bag, where it can be seen that the light sensor 13 on the electronic book 1 is located in the container 3 after being placed. Therefore, it cannot sense the exposure of light, and immediately activates the standby or shutdown function to achieve power saving. Figure 3b reveals that there is a light sensor 13 on the front of the e-book 1. When the user wants to activate the standby or shutdown function, a shield 4 is placed on the light sensor 13 to block the light from shining on the light sensor 13. , the light sensor 13 can start the standby or shutdown function, so as to achieve the effect of power saving. In addition, the light sensor 13 in the above figures can be replaced by a photocell. When the photocell is not in the charging state, the standby or shutdown function is activated.

Please refer to FIG. 4 , which is a schematic diagram of another embodiment of the electronic book of the present invention. It is disclosed that the electronic book 1 has a display surface 10 , and a gravity sensor 14 is also provided on the electronic book 1 . Please refer to the top of FIG. 4 , where the electronic book 1 is positioned with the display surface 10 facing up, which is also the position where the electronic book 1 is usually used. At this time, the gravity direction 14 ′ is directed to the normal direction of the display surface 10 In contrast to ND, it can also be said that the gravity direction 14 ′ is located on the back side of the display surface 10 . At this moment, the electronic book 1 is in the use state and does not enter the standby or shutdown state. In other words, when the angle between the gravity direction 14' and the normal direction ND is greater than 90 degrees, the electronic book 1 can be regarded as being in use. Please refer to the bottom of Fig. 4 again, once the e-book 1 is not used but placed upside down on the desktop (not shown in the figure), or placed on the passenger seat next to the driver's seat (not shown in the figure), the direction of gravity 14' It is the same as or close to the normal direction ND of the display surface 10 , so it can be said that the gravitational direction 14 ′ is located on the same side of the display surface 10 . At this point, the electronic book 1 is in a non-use state and enters a standby or power-off state. In other words, when the angle between the gravity direction 14' and the normal direction ND is less than 90 degrees, it can be considered that the electronic book 1 is in the non-use state, and thus enters the standby or shutdown state to achieve the power saving effect.

Please refer to FIG. 5 , which is a schematic diagram of the architecture of the e-book of the present invention. It is disclosed that the electronic book includes a main controller 100 for controlling the use of the electronic book, and the electronic book also includes a memory module 104 for storing data and is electrically connected with the main controller 100 . An I/O interface 103 is electrically connected to the main controller 100 and indirectly electrically connected to the memory module 104. The I/O interface 103 is used for inputting data into or outputting data from the memory module. An electronic paper module 102 for displaying data is electrically connected to the main controller 100 and indirectly electrically connected to the memory module 104 . The electronic paper module 102 is located on the display surface 10 in FIGS. 1 to 4 . A power supply device, usually a power controller 101, electrically connected to the main controller 100, and indirectly electrically connected to the electronic paper module 102 and the memory module 104; and an environmental sensor 105, electrically connected to the main controller 100 and power controller 101. Generally, the environment sensor 105 can be composed of the light sensor 13 or the gravity sensor 14 alone, or both of them. In addition, the environment sensor 105 can also be directly disposed in the power controller 101 or the main controller 100 . As far as the light sensor is concerned, there is a light sensitivity value inside. If the external light received by the light sensor 13 is lower than the light sensitivity value, the light sensor 13 notifies the power controller 101 to reduce the power output. Of course, the notification from the light sensor can also indirectly control the power controller 101 through the main controller 100 .

In addition, when the environmental sensor 105 includes the light sensor 13 and the gravity sensor 14, the main controller 100 determines which sensor is given priority. Generally speaking, the light sensor 13 can be selected as the priority. This is because if you use an e-book on a vehicle, sometimes you will encounter up and down bumps, so the gravity direction 14' of the gravity sensor 14 will be affected by inertia. And point to the display surface 10, so that will cause wrong judgment and reduce the power output. As for the use in a static environment, the environment sensor 105 can be set to have the same priority level as the two sensors.

From the above drawings and their descriptions, it can be seen that the present invention actually provides a control method for e-books, especially the control method for power supply and power output, through the action of environmental sensors, such as light sensors Whether the sensor is sensitive to light or not, and the direction of the gravity sensor, determine the state of the e-book power control. For the detailed control method, please refer to the above, and will not repeat it here. However, in short, it is to achieve the effect of power control by blocking the light from shining on the light sensor, or changing the direction of the display surface of the e-book, and then achieve the effect of energy saving and power saving.

To sum up, the present invention controls the power supply of the e-book through an environmental sensor to achieve the effect of saving energy and electricity. Through the use of the light sensor or the gravity sensor, the user can reduce the power output of the e-book when the e-book is not in use through a very simple and intuitive method of use, usually to make it Entering the standby or shutdown state is very convenient and can be completed without much brainpower. For example, when the user turns off the desk lamp, or puts the e-book into a protective case, a paper bag, etc., or covers the e-book with a shield. Covering the book, especially the light sensor, enables the e-book to reduce the power output. In addition, there is a similar situation, that is, the user leans the e-book towards himself, as if holding it in front of his chest, close to his chest. This situation often occurs when moving in a crowded environment, such as in a car. In order to reduce collisions, passengers You will bring the item close to you, but you cannot read the e-book when you hold the e-book close to your chest, so the present invention can also achieve energy-saving and power-saving effects in this case . Alternatively, the e-book can be turned upside down, from the original face up to the back face up, so that the gravity sensor can be triggered to reduce the power output of the e-book, or if the light sensor is set on the front of the e-book, When the e-book is facing down, it can also block the light from shining on the light sensor, and trigger the function of reducing the power output, so that the e-book enters a standby or shutdown state, achieving energy-saving and power-saving effects. It can be seen that, through the environmental sensor, the present invention can simply and intuitively achieve energy-saving and power-saving effects, and the present invention has made great contributions to related technologies such as e-books.

The above-mentioned embodiments are only examples for the convenience of description, and although those skilled in the art may make various modifications according to Ren Shijiang's thought, they are all within the scope of protection intended by the appended patent application.
