The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The disclosed embodiment is an accessory for an electronic device. The electronic device is a reading terminal that can operate and read electronic books, and fig. 1 shows a schematic diagram of the reading terminal.

As shown in fig. 1, the reading terminal 100 includes: a processor 101, a communication interface 102, a power component 103, a display 104, an audio component 105, a memory 106, and a key interface 107.

The processor 101 may be a central processing unit CPU or a specific integrated circuit ASIC or an integrated circuit configured to implement embodiments of the present disclosure. Furthermore, the reading terminal 100 can include multiple processors, which can be of the same type or different types of processors, such as multiple CPUs, multiple ASICs, or a CPU plus an ASIC.

The communication interface 102 is configured as a module for wireless communication between the reading terminal 100 and other devices, including bluetooth 112, WiFi antenna 122, 4G/5G antenna communication 132, and the like. In another embodiment, the communication interface 102 further includes a Near Field Communication (NFC) module to facilitate short-range communications.

The power supply component 103 provides power to the various components of the reading terminal 100. The power supply assembly 103 may include an external power interface 113 and a charging interface circuit 123.

The display 104 is an interactive display interface between the reading terminal 100 and the user, and includes an electromagnetic film 114, a capacitive screen 124, an ink screen 134, and the like.

The electromagnetic film 114 is used for receiving signals of an electromagnetic pen, and is distinguished by magnetic field changes generated by inductors under an electromagnetic pen operating process and a panel, the electromagnetic pen is a signal transmitting end, the electromagnetic film 114 is a signal receiving end, magnetic flux changes when the electromagnetic pen is close to induction, and position points are defined through operation.

The capacitive screen 124 is a touch screen for receiving signals from a user's finger input and includes one or more touch sensors to detect gestures on the touch, slide and touch screen panels. The touch sensor may detect not only the boundary of a touch or slide action, but also the duration and pressure associated with the touch or slide operation.

The electromagnetic film 114 and the capacitive screen 124 are collectively referred to as a touch screen 174.

The ink screen 134 is a display screen using electronic ink, also called electronic paper display technology, and has a main structure including a top transparent electrode layer, an electrophoretic layer, and a bottom electrode pixel layer. The electrophoretic layer is internally provided with a plurality of fine microcapsules, the microcapsules are provided with transparent liquid and a plurality of tiny electrophoretic particles, the electrophoretic particles are distributed in the transparent electrophoretic liquid to form a suspension system, the surfaces of the electrophoretic particles are easy to adsorb electric charges, and the particles capable of inducing the electric charges can move under the action of an external electric field.

Specifically, the electrophoretic particles are classified into negatively charged black particles and positively charged white particles. When a positive voltage is applied to the bottom electrode pixel layer, the white particles are repelled to move toward the top transparent electrode layer, and the black particles are attracted to move toward the bottom electrode pixel layer, in which case the pixel appears white. Conversely, when a negative voltage is applied to the bottom electrode pixel layer, the white particles are attracted to move toward the bottom electrode pixel layer, the black particles are repelled to move toward the top transparent electrode layer, and the pixel is displayed as black.

The display 104 also includes a sensing component 144 configured with a plurality of various sensors for providing various aspects of status assessment for the electronic device. For example: the temperature sensor 154 in the sensing assembly 144 can detect the temperature change of the display 104, and the detected temperature is transmitted to the processor 101 and then to the timing controller 108 as a parameter for table lookup.

The display 104 further includes a front light and light guide plate 164 disposed at a side of the display 104 to provide a stable and uniform light source.

The audio component 105 is configured to output and/or input audio signals. For example, the audio component 105 includes a microphone 118, and when the reading terminal 100 needs to receive speech, such as a call mode, a recording mode, and a speech recognition mode, the microphone 118 is configured to receive external audio signals. The audio module 105 further comprises a speaker 128 for outputting audio signals.

The memory 106 is used for storing programs, electronic books and notes, and may be a high-speed RAM memory or a non-volatile memory (non-volatile memory), such as a disk memory.

The key interface 107 is used for controlling the page turning of the user, and is generally physical keys, which are disposed at the side of the reading terminal 100 and include a front page turning key and a back page turning key.

The timing controller 108 is used for finding out the corresponding control parameter, i.e. the driving waveform, through the lookup table. Since the black and white particles in the ink screen 134 are sensitive to temperature, the lower the temperature, the less active the particles, the longer it takes to move to the same position in the microcapsule at room temperature; the particles move faster when the temperature is higher, and the time required to move to the same location in the microcapsule is relatively shorter compared to the time required at normal temperature. The temperature sensor 154 collects temperature data on the display 104, and the timing controller 108 finds corresponding control parameters according to the temperature data to select an appropriate driving waveform.

The display driver 109 converts the driving waveform into a control signal to drive the ink particles on the ink screen 134 to move, so that image data to be displayed can be imaged on the ink screen 134.

In one application scenario of this embodiment, the reading terminal 100 includes an ink screen 134 to display function options to switch functions. When the touch screen 174 receives a touch instruction generated by pressing the function option by the user, and the processor 101 receives the touch instruction, the page turning key or the volume key of the key interface 107 is determined to start the function of the switch key. In other words, as long as the key for switching the function map is set in advance, the designated key can be changed to the switch key by displaying the function option on the ink screen 134 and pressing the function option by the user.

The electronic equipment accessory comprises a control key, a fixing piece and a flexible circuit board. One side of the flexible circuit board is provided with an interface which is electrically connected with the electronic equipment, and the other side of the flexible circuit board is provided with two control components which respectively receive control signals from the control keys and transmit the control signals to the electronic equipment through the interface so as to control the electronic equipment to execute corresponding operations.
