Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0022] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0023] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of ink screen technology.

[0024] Research has found that the ink screen electronic paper technology can simulate the text and images on paper. Ordinary ink screen electronic paper books do not have the ability to independently judge whether to remind users that they are too close to the screen based on the user's distance. This cannot better protect the user's eyes and is likely to cause myopia and other problems.

[0025] Existing ink screen electronic paper books do not have the function of autonomously judging the distance between the user and the screen, and cannot remind the user if he / she is too close to the screen according to the distance between the user, and cannot better protect the eyes of teachers and students.

[0026] Based on this, an embodiment of the present application provides an e-ink screen electronic paper book, which can be connected to the e-ink screen control circuit through the distance sensor, and the e-ink screen control circuit is connected to the screen controller, so that when the distance between the user and the e-ink screen electronic paper book is too close, a target prompt screen is displayed on the ink screen. The target prompt screen is used to remind the user to protect his eyes, thereby solving the problem in the prior art that the existing e-ink screen electronic paper book does not have the ability to independently judge the distance between the user and the screen, and cannot remind the user that the user is too close to the screen according to the distance of the user, and cannot better protect the eyes of teachers and students, thereby achieving the effect of preventing the user from becoming myopic due to being too close to the ink screen.

[0027] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an ink screen electronic paper book provided in an embodiment of the present application. Figure 1 As shown in , the ink screen electronic paper book provided in the embodiment of the present application includes: an ink screen 101, a sensor area 102, a distance sensor 103 and an ambient light sensor 104.

[0028] A sensor area is formed at a target position of the ink screen, and the distance sensor is arranged in the sensor area to measure the distance between the user and the ink screen electronic paper book.

[0029] The ink screen electronic paper book also includes an ambient light sensor, and the ambient light sensor is arranged in the sensor area.

[0030] Specifically, the distance sensor is connected to the ink screen control circuit, and the ink screen control circuit is connected to the screen controller, so that when the user is too close to the ink screen e-book, a target prompt screen is displayed on the ink screen, and the target prompt screen is used to remind the user to protect his eyes.

[0031] Here, this application modifies the original ink screen head area, increases the sensor area, and ensures that the ink screen e-book can display normally.

[0032] Exemplarily, the present application adds a distance sensor in the sensor area, and obtains the distance between the user and the screen through the distance sensor. An ambient light sensor is added in the sensor area, and obtains the brightness of the surrounding ambient light through the ambient light sensor.

[0033] For example, see Figure 2 , Figure 2 Circuit of the ink screen electronic paper book provided in the embodiment of the present application Figure 1 .like Figure 2 As shown in the figure, the circuit of the ink screen electronic paper book provided in the embodiment of the present application Figure 1 , including: a distance sensor 103, an ink screen control circuit 201, a screen controller 202, and an ink screen 101.

[0034] Among them, the distance sensor is connected to the ink screen control circuit, the ink screen control circuit is connected to the screen controller, and the screen controller is connected to the ink screen, so that when the distance between the user and the ink screen e-book is too close, a target prompt screen is displayed on the ink screen, and the target prompt screen is used to remind the user to protect his eyes.

[0035] Specifically, the distance sensor measures the distance between the user and the ink screen electronic paper reader once every 5 seconds.

[0036] Optionally, the target prompt image is stored in the screen controller.

[0037] Specifically, the screen controller is used to display a target prompt screen on the ink screen according to the target level.

[0038] Specifically, the ambient light sensor is connected to the ink screen control circuit, and the ink screen control circuit is connected to the screen controller, so that the ink screen e-paper book adjusts the brightness of the ink screen according to the brightness of the environment surrounding the ink screen e-paper book measured by the ambient light sensor.

[0039] For example, see Figure 3 , Figure 3 Circuit of the ink screen electronic paper book provided in the embodiment of the present application Figure 2 .like Figure 3 As shown in the figure, the circuit of the ink screen electronic paper book provided in the embodiment of the present application Figure 2 , including: an ambient light sensor 104, an ink screen control circuit 201, a screen controller 202, and an ink screen 101.

[0040] Among them, the ambient light sensor is connected to the ink screen control circuit, the ink screen control circuit is connected to the screen controller, and the screen controller is connected to the ink screen, so that the ink screen e-paper book adjusts the brightness of the ink screen according to the brightness of the environment surrounding the ink screen e-paper book measured by the ambient light sensor.

[0041] Specifically, the ambient light sensor is used to measure the light Lux value of the environment around the ink screen electronic paper book, and the light Lux value is used to indicate the brightness of the environment around the ink screen electronic paper book.

[0042] In this way, the present application can avoid the problem that the existing ink screen e-paper books do not have the ability to self-perceive the brightness of the surrounding environment, and cannot adjust the brightness of the screen according to the brightness of the surrounding environment, and cannot better protect the eyes of teachers and students. It provides the ink screen e-paper books with the ability to perceive the brightness of the surrounding environment, and enables the ink screen e-paper books to self-adjust the screen according to the brightness of the surrounding environment.

[0043] Optionally, the ink screen control circuit is a CPU, and the CPU is used to determine whether the distance between the user and the ink screen e-book is less than a preset distance threshold. If the distance between the user and the ink screen e-book is less than the preset distance threshold, a target level is sent to cause the screen controller to display a target prompt screen.

[0044] Optionally, a plurality of light Lux intervals are pre-set in the CPU.

[0045] The CPU is further used to determine a Lux interval where the light Lux value is located according to the light Lux value and multiple light Lux intervals, and to send an indication value corresponding to a Lux interval where the light Lux value is located, so that the screen controller adjusts the brightness of the ink screen according to the indication value.

[0046] For example, see Figure 4 , Figure 4 Circuit of the ink screen electronic paper book provided in the embodiment of the present application Figure 3 .like Figure 4 As shown in the figure, the circuit of the ink screen electronic paper book provided in the embodiment of the present application Figure 3 , including: a distance sensor 103, an ambient light sensor 104, a CPU 401, a screen controller 202, and an ink screen 101.

[0047] The distance sensor 103 and the ambient light sensor 104 are connected to the CPU 401 respectively, the CPU 401 is connected to the screen controller 202 , and the screen controller 202 is connected to the ink screen 101 .

[0048] Exemplarily, when the CPU determines that the distance between the user and the ink screen e-reader is less than a preset distance threshold, the CPU sends a target level to the screen controller, and the screen controller displays a target prompt screen on the ink screen according to the target level.

[0049] Exemplarily, when the light Lux value falls within the third light Lux interval, the CPU sends a third indication value to the screen controller, and the screen controller adjusts the brightness of the ink screen according to the ink screen brightness corresponding to the third indication value, so that the brightness of the ink screen e-book matches the brightness of the surrounding environment, avoiding damage to the user's eyesight due to the mismatch between the screen brightness and the brightness of the surrounding environment.

[0050] The ink screen e-paper book provided in the embodiment of the present application can be connected to the ink screen control circuit through the distance sensor, and the ink screen control circuit is connected to the screen controller, so that when the distance between the user and the ink screen e-paper book is too close, a target prompt screen is displayed on the ink screen. The target prompt screen is used to remind the user to protect his eyes, thereby solving the problem in the prior art that the existing ink screen e-paper books do not have the ability to independently judge the distance between the user and the screen, cannot remind the user when the user is too close to the screen according to the distance of the user, and cannot better protect the eyes of teachers and students, thereby achieving the effect of preventing the user from becoming myopic due to being too close to the ink screen.
