[0047] Please refer to Figure 1 and Figure 2 as shown, which are respectively a schematic diagram of an anti-display stamping processing system of an embodiment and a schematic diagram of system components of an anti-display stamping system of an embodiment. The anti-display stamping processing system (hereinafter simply referred to as the processing system 1000) includes a display screen 100 and a computer main unit 200. The processing system 1000 can be applied to a personal computer, a notebook computer or a mobile communication device, such as: a mobile phone or a tablet computer. The display screen 100 is connected to the computer main unit 200. The display screen 100 is used to play relevant pictures provided by the computer main unit 200.

[0048] The computer main unit 200 has a communication unit 210, a display interface 220, a storage unit 230, and a processing unit 240. The processing unit 240 is connected to the communication unit 210, the display interface 220, and the storage unit 230. The communication unit 210 receives an external connection signal 310. The connection signal 310 can be transmitted to the computer main unit 200 in a wired or wireless manner. The communication unit 210 forwards the connection signal 310 to the processing unit 240. In some embodiments, the types of the communication unit 210 are Bluetooth wireless communication protocol (Bluetooth), ZigBee protocol, wireless network, near field communication protocol (Near Field Communication), or universal serial bus (Universal Serial Bus).

[0049] The display interface 220 is connected to the display screen 100. The types of the display interface 220 can be, but are not limited to, high definition multimedia interface (High Definition Multimedia Interface, HDMI), display port interface (DisplayPort, DP), video graphics array interface (Video Graphics Array, VGA), or digital video interface (Digital Visual Interface, DVI). The processing unit 240 sends a digital signal to the display screen 100 through the display interface 220, so that the display screen 100 plays the relevant screens of the operating system 231 and its application programs 232.

[0050] The storage unit 230 stores an operating system 231, multiple application programs 232, and an anti-burn-in program 233. The processing unit 240 can execute the anti-burn-in program 233 alone, or can execute the application program 232 and the anti-burn-in program 233 at the same time. When the processing unit 240 executes the application program 232, the processing unit 240 drives the display screen 100 to play the corresponding working window. Hereinafter, the desktop screen 111 of the running application program 232 is collectively referred to as the program screen 112. The screen of the preset desktop of the operating system 231 is called the desktop screen 111. For reference, see Figure 6 .

[0051] Taking the Windows operating system (Windows OS) of Microsoft Corporation as an example. After the user starts the computer main unit 200, the computer main unit 200 will enable the Windows operating system 231. The preset working area of the Windows operating system 231 is played on the display screen 100, and this preset working area is the desktop screen 111. Similarly, for other windowed operating systems 231 or command line operating systems 231, the preset working area belonging to them is also called the desktop screen 111.

[0052] When the anti-burn-in program 233 is started, the anti-burn-in program 233 reads the panel properties of the display screen 100. In some embodiments, the panel properties include the current resolution, maximum resolution, panel size, refresh rate, response time, or color gamut range. The panel properties can be stored in the read only memory (ROM) or programmable read-only memory (PROM) of the display screen 100, or stored in the storage unit 230. To further illustrate the operation process of the anti-burn-in program 233, please refer to Figure 3 :

[0053] Step S210: The computer host executes the anti-burn-in program;

[0054] Step S220: The anti-burn-in program detects whether the connection signal is interrupted;

[0055] Step S230: When the computer host receives that the connection signal is interrupted, the computer host switches the screen of the display screen to the desktop screen;

[0056] Step S240: The computer host obtains the desktop screen as the protection screen;

[0057] Step S240: The computer host sets a playback path in the display screen according to the panel properties of the display screen; and

[0058] Step S260: The computer host displays the protection screen along the playback path.

[0059] First, the processing unit 240 executes the anti-burn-in program 233. The anti-burn-in program 233 determines whether the connection signal 310 has been received. If the anti-burn-in program 233 has not received the connection signal 310, the computer host 200 waits for the connection of the connection signal 310. If the computer host 200 has received the connection signal 310, the anti-burn-in program 233 determines whether the connection signal 310 is interrupted.

[0060] In one embodiment, the communication unit 210 is signal-connected to the peripheral device 300. The peripheral device 300 can be, but is not limited to, a mobile phone, or can also be a USB device. The communication unit 210 can receive the connection signal 310 of the peripheral device 300 by means of cable connection or interface connection, or can also receive the connection signal 310 through a wireless communication protocol. The communication protocol of the peripheral device 300 matches that of the communication unit 210. The computer host 200 can send a communication request to the peripheral device 300. The peripheral device 300 generates a corresponding response signal to the computer host 200 according to the communication request, and the foregoing response signal is the connection signal 310.

[0061] After the anti-stamping program 233 is executed, the anti-stamping program 233 starts to determine whether the connection signal 310 is interrupted. When a signal interruption occurs between the computer host 200 and the peripheral device 300, it is called that the computer host 200 receives an interruption of the connection signal 310. If the computer host 200 interrupts receiving the connection signal 310, the anti-stamping program 233 switches the program screen 112 to the desktop screen 111. The anti-stamping program 233 can switch (or scale) the screen of the running application 232 to the desktop screen 111 through functions such as the window scaling function. In some embodiments, when the anti-stamping program 233 receives an interruption of the connection signal 310, after the anti-stamping program 233 times through a preset time, the anti-stamping program 233 switches from the program screen 112 to the preset desktop and obtains the desktop screen 111.

[0062] After switching to the desktop screen 111, the anti-stamping program 233 obtains the desktop screen 111 and records the obtained screen as the protection screen 130. The anti-stamping program 233 is based on the panel information of the display screen 100. The anti-stamping program 233 generates a playback path 420 according to the panel attributes. Among them, the playback path 420 includes horizontal movement, vertical movement, diagonal movement or a combination thereof, so that the playback path 420 forms a closed path. The display screen can move cyclically along the playback path 420. The anti-stamping program 233 can read the panel information when it is initially executed, or read the panel information when the connection signal is interrupted.

[0063] In some embodiments, the anti-stamping program 233 selects one of the current resolution or the maximum resolution. In addition to selecting at least one pixel as the unit movement distance 410, the anti-stamping program 233 can calculate a unit movement distance 410 according to the selected resolution. The anti-stamping program 233 calculates the pixels per inch (Pixels Per Inch, PPI) of the corresponding display screen 100 with the selected resolution. The overall length of the playback path 420 can also be determined according to one of the current resolution or the maximum resolution.

[0064] The anti-stamping program 233 looks up a scale table (not shown), and the scale table records multiple PPIs and their corresponding pixel quantities. The anti-stamping program 233 selects the corresponding pixel quantity as the unit movement distance 410 according to the PPI and the scale table. The unit movement distance 410 is the movement distance between two consecutive protection screens 130. Please refer to Figure 4 . Figure 4 It is a schematic diagram after the protection screen 130 moves horizontally by one unit movement distance 410.

[0065] Next, the anti-burn-in program 233 selects multiple directional movements from horizontal movement, vertical movement, or diagonal movement. The anti-burn-in program 233 can form a closed path with the selected directional movements, or the user can arrange the selected directional movements by themselves. To further illustrate the playback path 420, please refer to Figure 5 and Figure 6 . Figure 5 Select any area and one of the pixels (i.e., the gray square in Figure 5 ) in the protection screen 130 as the starting point of the playback path 420, thereby serving as the movement of the entire protection screen 130. The arrow of the playback path 420 indicates different directional movements.

[0066] In Figure 5 , the playback path 420 is a 4*4 pixel closed path, which means two sets of horizontal movements and two sets of vertical movements. And the anti-burn-in program 233 selects "1" pixel as the unit movement distance 410. After each specified time, the anti-burn-in program 233 moves the protection screen 130 by "1" unit movement distance 410 and plays it on the display screen 100. The described movement is the playback of the protection screen 130 at different positions at different times, as shown in Figure 6 . Figure 6 Taking the desktop screen 111 of the Microsoft Windows operating system 231 as the default desktop and using the default desktop as the protection screen 130 as an example. The protection screen 130 will be displayed on the playback path 420 on the display screen 100 in a time-sharing manner. When viewed microscopically by the viewer, the protection screen 130 will move. Macroscopically speaking, since the protection screen 130 moves in units of pixels for the movement distance 410, it is not easy for the viewer to notice the change. In addition, the anti-burn-in program 233 can also determine the number of frames when the protection screen 130 moves according to the refresh rate or response time.

[0067] In some embodiments, when one side edge of the protection screen 130 moves out of the side edge of the display screen 100, the anti-burn-in program 233 can play the edge of the protection screen 130 that has moved out from the other side edge of the display screen 100. For example, when a part of the protection screen 130 moves out from the right side edge of the display screen 100, the moved-out protection screen 130 will be displayed on the left side edge of the display screen 100.

[0068] In some embodiments, when the anti-burn-in program 233 executes step S260, the anti-burn-in program 233 still detects whether the communication unit 210 re-receives the connection signal 310. Please refer to Figure 7When the communication unit 210 re-receives the connection signal 310, the anti-burn-in program 233 aborts the display screen 100 from playing the protection screen 130. The anti-burn-in program 233 calls the application program executed before playing the protection screen 130, so as to restore the working environment on the display screen 100 (corresponding to step S261). If there is no such executed application program, the anti-burn-in program 233 will display the preset desktop.

[0069] In some embodiments, when the anti-burn-in program 233 initially obtains the protection screen 130, the anti-burn-in program 233 records the overall brightness value of this protection screen 130. When the protection screen 130 moves along the playback path 420, the anti-burn-in program 233 obtains the current brightness value of the protection screen 130 at the new position. The anti-burn-in program 233 compares whether the overall brightness value is consistent with the current brightness value. If the overall brightness value is not consistent with the current brightness value, the anti-burn-in program 233 adjusts the current brightness value to be consistent with the overall brightness value.

[0070] The anti-display burn-in processing system 1000 and its method provide a computer host 200 and a method for detecting a connection signal 310 to prevent screen burn-in. The computer host 200 can trigger the anti-burn-in program 233 in real time when the user leaves, and generate a playback path 420 according to the panel attributes of the display screen 100. The computer host 200 obtains the preset desktop of the operating system 231, and plays the obtained desktop screen 111 along the playback path 420. Since the desktop screen 111 is played by moving at pixel interval distances, it can ensure that each pixel on the liquid crystal panel has a change in operation. And playing the desktop screen 111 can also ensure that other users cannot view the application program 232 operated by the user.
