The touch-sensitive surface 431, also referred to as a touch display screen or a touch pad, may collect touch operations by a user on or near the touch-sensitive surface 431 (e.g., operations by a user on or near the touch-sensitive surface 431 using any suitable object or attachment such as a finger, a stylus, etc.) and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface 431 may comprise both a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 480, and can receive and execute commands sent by the processor 480. In addition, the touch-sensitive surface 431 may be implemented in various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 430 may include other input devices 432 in addition to the touch-sensitive surface 431. In particular, other input devices 432 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit 440 may be used to display information input by or provided to the user and various graphical user interfaces of the mobile terminal 400, which may be made up of graphics, text, icons, video, and any combination thereof. The Display unit 440 may include a Display panel 441, and optionally, the Display panel 441 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch sensitive surface 431 may overlay the display panel 441, and when a touch operation is detected on or near the touch sensitive surface 431, the touch operation is transmitted to the processor 480 to determine the type of the touch event, and then the processor 480 provides a corresponding visual output on the display panel 441 according to the type of the touch event. Although the touch-sensitive surface 431 and the display panel 441 are shown as two separate components to implement input and output functions, in some embodiments, the touch-sensitive surface 431 and the display panel 441 may be integrated to implement input and output functions.
The mobile terminal 400 may also include at least one sensor 450, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 441 according to the brightness of ambient light, and a proximity sensor that may generate an interrupt when the folder is closed or closed. As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when the mobile phone is stationary, and can be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be further configured on the mobile terminal 400, detailed descriptions thereof are omitted.
The audio circuit 460, speaker 461, microphone 462 may provide an audio interface between a user and the mobile terminal 400. The audio circuit 460 may transmit the electrical signal converted from the received audio data to the speaker 461, and convert the electrical signal into a sound signal for output by the speaker 461; on the other hand, the microphone 462 converts the collected sound signal into an electric signal, which is received by the audio circuit 460 and converted into audio data, which is then processed by the audio data output processor 480, and then transmitted to, for example, another terminal via the RF circuit 410, or output to the memory 420 for further processing. The audio circuit 460 may also include an earbud jack to provide communication of peripheral headphones with the mobile terminal 400.
The mobile terminal 400, which may assist the user in receiving requests, sending information, etc., through the transmission module 470 (e.g., a Wi-Fi module), provides the user with wireless broadband internet access. Although the transmission module 470 is shown in the drawing, it is understood that it does not belong to the essential constitution of the mobile terminal 400 and may be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 480 is a control center of the mobile terminal 400, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the mobile terminal 400 and processes data by operating or executing software programs and/or modules stored in the memory 420 and calling data stored in the memory 420, thereby integrally monitoring the mobile terminal. Optionally, processor 480 may include one or more processing cores; in some embodiments, processor 480 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 480.
The mobile terminal 400 may also include a power supply 490 (e.g., a battery) for powering the various components, which in some embodiments may be logically connected to the processor 480 via a power management system that may be configured to manage charging, discharging, and power consumption. The power supply 490 may also include any component including one or more dc or ac power sources, recharging systems, power failure detection circuitry, power converters or inverters, power status indicators, and the like.
Although not shown, the mobile terminal 400 further includes a camera (e.g., a front camera, a rear camera, etc.), a bluetooth module, a flashlight, etc., which are not described in detail herein. Specifically, in the present embodiment, the display unit of the mobile terminal 400 is a touch screen display.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalents or equivalent substitutions fall within the protection scope of the claims of the present invention.
In summary, although the preferred embodiments of the present invention have been described above, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
