The computer-readable storage medium may include, but is not limited to, any type of disk including floppy disks, optical disks, DVD, CD-ROMs, microdrive, and magneto-optical disks, ROMs, RAMs, EPROMs, EEPROMs, DRAMs, VRAMs, flash memory devices, magnetic or optical cards, nanosystems (including molecular memory ICs), or any type of media or device suitable for storing instructions and/or data.
Referring to fig. 6, a schematic structural diagram of an electronic device according to an embodiment of the present invention is shown, where the electronic device may be used to implement the control method of the large-screen display device provided in the above-described embodiment.
Specifically, the method comprises the following steps:
the memory 1020 may be used to store software programs and modules, and the processor 1080 executes various functional applications and data processing by operating the software programs and modules stored in the memory 1020. The memory 1020 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the terminal device, and the like. Further, the memory 1020 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. Accordingly, memory 1020 may also include a memory controller to provide access to memory 1020 by processor 1080 and input unit 1030.
The input unit 1030 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 1030 may include a touch-sensitive surface 1031 (e.g., a touch screen, a touchpad, or a touch frame). The touch-sensitive surface 1031, also referred to as a touch display screen or a touch pad, may collect touch operations by a user (such as operations by a user on or near the touch-sensitive surface 1031 using any suitable object or attachment, such as a finger, a stylus, etc.) on or near the touch-sensitive surface 1031 and drive the corresponding connection device according to a preset program. Optionally, the touch sensitive surface 1031 may comprise two parts, a touch detection means 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, sends the touch point coordinates to the processor 1080, and can receive and execute commands sent by the processor 1080. In addition, the touch-sensitive surface 1031 may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves.
The display unit 1040 may be used to display information input by or provided to a user and various graphical user interfaces of the terminal device, which may be made up of graphics, text, icons, video, and any combination thereof. The Display unit 1040 may include a Display panel 1041, and optionally, the Display panel 1041 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 1031 may overlay the display panel 1041, and when a touch operation is detected on or near the touch-sensitive surface 1031, the touch operation is transmitted to the processor 1080 for determining the type of the touch event, and the processor 1080 then provides a corresponding visual output on the display panel 1041 according to the type of the touch event. Although the touch-sensitive surface 1031 and the display panel 1041 may be two separate components that implement input and output functions, in some embodiments, the touch-sensitive surface 1031 may be integrated with the display panel 1041 that implements input and output functions.
The processor 1080 is a control center of the terminal device, connects various parts of the whole terminal device by using various interfaces and lines, and executes various functions of the terminal device and processes data by operating or executing software programs and/or modules stored in the memory 1020 and calling data stored in the memory 1020, thereby monitoring the whole terminal device. Optionally, processor 1080 may include one or more processing cores; processor 1080 may integrate an application processor that handles operating system, user interfaces, applications, etc. and a modem processor that handles wireless communications. It is to be appreciated that the modem processor described above may not be integrated into processor 1080.
Specifically, in this embodiment, the display unit of the terminal device is a touch screen display, the terminal device further includes a memory, and one or more programs, where the one or more programs are stored in the memory, and the one or more programs are configured to be executed by the one or more processors, and the method for controlling the large-screen display device includes the steps of implementing the method for controlling the large-screen display device.
In the several embodiments provided in the present application, it should be understood that the disclosed apparatus and method may be implemented in other ways. The above-described device embodiments are merely illustrative, for example, the division of the unit is only a logical functional division, and there may be other division ways in actual implementation, such as: multiple units or components may be combined, or may be integrated into another system, or some features may be omitted, or not implemented. In addition, the coupling, direct coupling or communication connection between the components shown or discussed may be through some interfaces, and the indirect coupling or communication connection between the devices or units may be electrical, mechanical or other forms.
All functional units in the embodiments of the present invention may be integrated into one processing unit, or each unit may be separately used as one unit, or two or more units may be integrated into one unit; the integrated unit can be realized in a form of hardware, or in a form of hardware plus a software functional unit.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
