[0002] When a user is playing a shooting game and is hit by a flashbang, the screen will instantly turn completely white, causing discomfort to the user's eyes. Moreover, after the screen turns completely white, it will first display a whitening process before gradually returning to the original normal game screen. This will cause the user's reaction to the game to slow down. Summary of the invention

[0003] The invention provides a display device capable of adjusting grayscale value and a display method thereof, which can provide good display effect.

[0004] The display device with adjustable grayscale value of the present invention includes a display panel, a communication interface and a controller. The communication interface is used to receive display data of a display screen. The controller is electrically connected to the display panel and the communication interface, and is used to drive the display panel to display the display screen according to the display data. In response to the controller executing the flash bomb auxiliary function, the controller analyzes the display data to detect multiple grayscale values ​​of multiple pixels in the display screen. In response to the controller detecting that multiple grayscale values ​​of multiple pixels in the display screen are all higher than or equal to a first threshold, the controller adjusts the display data to reduce at least a portion of the multiple grayscale values.

[0005] In one embodiment of the present invention, in response to the controller detecting that the grayscale values ​​of the pixels in the display frame are all the first grayscale values, the controller adjusts the display data to reduce the grayscale values ​​of the pixels to the second grayscale values. The first grayscale value is greater than the second grayscale value.

[0006] In an embodiment of the present invention, the first grayscale value is 255, and the second grayscale value is 125.

[0007] In one embodiment of the present invention, in response to the controller detecting that the grayscale values ​​of the pixels in the display frame are all higher than or equal to the first threshold, the controller adjusts the display data to roll off the grayscale values.

[0008] In an embodiment of the present invention, the first threshold is 180.

[0009] In one embodiment of the present invention, in response to the controller detecting that the grayscale difference between any two adjacent pixels of the multiple pixels in the display image is greater than the second threshold, the controller adjusts the display data to reduce the grayscale value of one of any two adjacent pixels of the multiple pixels so that the grayscale difference between any two adjacent pixels of the multiple pixels is less than the third threshold.

[0010] In an embodiment of the present invention, the first threshold is greater than the second threshold and the third threshold, and the second threshold is greater than the third threshold.

[0011] In an embodiment of the present invention, the second threshold is 125, and the third threshold is 50.

[0012] In one embodiment of the present invention, the display device further comprises a five-way key. The five-way key is electrically connected to the controller. In response to the five-way key being triggered, the controller executes the flash bomb auxiliary function.

[0013] The display method with adjustable grayscale values ​​of the present invention includes the following steps: receiving display data of a display screen through a communication interface; in response to the controller executing a flash bomb auxiliary function, analyzing the display data through the controller to detect multiple grayscale values ​​of multiple pixels in the display screen; in response to the controller detecting that multiple grayscale values ​​of multiple pixels in the display screen are all higher than or equal to a first threshold, adjusting the display data through the controller to reduce at least a portion of the multiple grayscale values; and driving the display panel through the controller to display the adjusted display screen according to the adjusted display data.

[0014] Based on the above, the display device and display method capable of adjusting grayscale values ​​of the present invention can automatically detect pixel changes of the display image through the display device, and automatically adjust the display data to provide a good display effect.

[0029] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0030] Figure 1 FIG. 1 is a schematic diagram of a display device capable of adjusting grayscale values ​​according to an embodiment of the present invention. Figure 1 , the display device 100 includes a controller 110, a communication interface 120 and a display panel 130. The controller 110 is electrically connected to the communication interface 120 and the display panel 130. The display device 100 can be connected to the computer host 200 through the communication interface 120. In this embodiment, the computer host 200 can execute a game program and provide display data of a game screen to the display device 100, so that the display device 100 can display a corresponding display screen through the display panel 130 according to the display data, but the present invention is not limited to the game screen. In this embodiment, the display device 100 has a function of adjusting the grayscale value.

[0031] In this embodiment, the controller 110 may include a display driver, a memory, and related control logic chips. The controller 110 may obtain display data (display signal) from the computer host 200 through the communication interface 120, and may adjust the display data to drive the display panel 130. In this embodiment, the display panel 130 may be, for example, a liquid crystal display panel, a light-emitting diode (LED) display panel, an organic light-emitting diode (OLED) display panel, or a quantum dot display panel, but the present invention is not limited thereto.

[0032] Figure 2 FIG. 1 is a flow chart of a display method capable of adjusting grayscale values ​​according to an embodiment of the present invention. Figure 1 as well as Figure 2, the display device 100 may perform the following steps S210 to S240. In step S210, the display device 100 may receive display data of a display screen provided by the computer host 200 through the communication interface 120. In the present embodiment, the display data is display data of a shooting game screen, but the present invention is not limited thereto. In step S220, in response to the controller 110 executing the flash bomb auxiliary function, the controller 110 may detect multiple grayscale values ​​of multiple pixels in the display screen. In the present embodiment, the display device 100 may further include a five-way key. The five-way key is electrically connected to the controller 110. In this regard, when the five-way key is triggered, the controller 110 may execute the flash bomb auxiliary function to automatically detect the display screen. The flash bomb auxiliary function means that the controller 110 can instantly detect the grayscale value of each pixel in the current display screen displayed by the display panel 130. In one embodiment, the five-way key may also be set on other input devices (such as a keyboard or a mouse) electrically connected to the display device 100 or the computer host 200. Furthermore, in another embodiment, the controller 110 may detect the grayscale values ​​of a plurality of pixels in a partial area of ​​the current display image displayed by the display panel 130 in real time.

[0033] In step S230, in response to the controller 110 detecting that the grayscale values ​​of the plurality of pixels in the display screen to be displayed by the display panel 130 are all higher than or equal to the first threshold value, the controller 110 may adjust the display data to reduce at least a portion of the plurality of grayscale values. In step S240, the controller 110 may drive the display panel 130 to display the adjusted display screen according to the adjusted display data. It should be noted that the grayscale value described in the present invention refers to the brightness level displayed by the pixel. In this embodiment, when the grayscale values ​​of the plurality of pixels of the current display screen to be displayed by the display panel 130 suddenly increase (i.e., the brightness of the screen increases, the screen is too bright, or the whole screen is reversed due to the influence of the flash bomb in the game), the controller 110 may automatically adjust the display data of the current (i.e., current frame) or next display screen (i.e., next frame) so that the brightness of the current (i.e., current frame) or next display screen (i.e., next frame) can be reduced immediately instead of waiting for the game program to reduce it. Therefore, the display device 100 of this embodiment can automatically detect whether the current display screen is too bright, and automatically adjust the display data of the next display screen received from the computer host 200 through the controller 110. The brightness adjustment operation of the display device 100 to adjust the screen will not notify the computer host 200, that is, the display device 100 does not affect or change the data output by the game program itself.

[0034] Figure 3 is a flow chart of a display method according to another embodiment of the present invention. Figure 1 as well as Figure 2, the display device 100 may perform the following steps S310 to S370. As mentioned above, steps S320, S340, and S360 may be performed simultaneously or sequentially.

[0035] In step S310, the controller 110 may execute the flash bomb auxiliary function to detect multiple grayscale values ​​of multiple pixels in the display image displayed by the display panel 130. In step S320, the controller 110 may detect whether the multiple grayscale values ​​are first grayscale values. If not, step S310 is re-executed. If so, in step S330, the controller 110 may reduce the multiple grayscale values ​​to second grayscale values.

[0036] Specifically, in this embodiment, when the controller 110 detects that the grayscale values ​​of the plurality of pixels in the display image are all the first grayscale values, the controller 110 may adjust the display data to reduce the grayscale values ​​of the plurality of pixels to the second grayscale value, wherein the first grayscale value is greater than the second grayscale value. In one embodiment, the first grayscale value may be 255, and the second grayscale value may be 125. Figure 4 , Figure 4 1 is a schematic diagram of the change of the display screen of an embodiment of the present invention. The display panel 130 may display the display screen 401 in the previous frame. When the display panel 130 is affected by the flash bomb in the game and may display the display screen 402 in the current frame, that is, the screen is white (completely white), the controller 110 can detect that the grayscale value of each pixel of the display screen 402 displayed by the display panel 130 is 255. Therefore, the display panel 130 can automatically reduce the grayscale values ​​of multiple pixels of the display screen 402 or the next display screen to immediately or quickly reduce the brightness of the display screen.

[0037] In step S340, the controller 110 may detect whether multiple grayscale values ​​are all higher than or equal to a first threshold value. If not, step S310 is re-executed. If so, in step S350, the controller 110 may roll down multiple grayscale values. Specifically, in the present embodiment, the first threshold value may be 180, but the present invention is not limited to this. When the controller 110 detects that multiple grayscale values ​​of multiple pixels in the display screen are all higher than or equal to 180, the controller 110 may adjust the display data to roll down multiple grayscale values. The controller 110 may reduce the value proportionally according to the size of the grayscale value, or reduce it by looking up a table, but the present invention is not limited to this. In this regard, reference is made to Figure 5 , Figure 51 is a schematic diagram of the change of the display screen of an embodiment of the present invention. The display panel 130 can display the display screen 402 in the previous frame. When the display panel 130 is affected by the flash bomb in the game and may display the display screen 403 in the current frame, that is, when the screen brightness is too high (or when the normal screen is not restored after the above step S330 is reduced), the controller 110 can detect that the grayscale value of each pixel of the display screen 402 displayed by the display panel 130 is greater than or equal to 180. The controller 110 can adjust the display data to scroll down multiple grayscale values. In this way, the controller 110 can quickly and effectively reduce or avoid the display screen displayed by the display panel 130 from being in a whitened state.

[0038] In step S360, the controller 110 may detect whether the grayscale difference between any two adjacent pixels of a plurality of pixels in the display screen is greater than a second threshold value. If not, step S310 is re-executed. If so, in step S370, the controller 110 may adjust the display data to reduce one of any two adjacent pixels of the plurality of pixels to have a higher grayscale value, so that the grayscale difference between any two adjacent pixels of the plurality of pixels is less than a third threshold value. Specifically, in the present embodiment, the first threshold value is greater than the second threshold value and the third threshold value, and the second threshold value is greater than the third threshold value. The second threshold value is 125, and the third threshold value is 50, but the present invention is not limited to this. The controller 110 may reduce the grayscale difference of the overall display screen. In this regard, the reference Figure 5 , the display panel 130 may display the display screen 402 in the previous frame. When the display panel 130 is affected by the flash bomb in the game and may display the display screen 403 in the current frame, that is, when the screen brightness of the entire display screen is still slightly bright (or when the normal screen is not restored after the above-mentioned step S330 or step S350 is reduced), the controller 110 may detect that the grayscale difference between any two adjacent pixels of the display screen 402 displayed by the display panel 130 is greater than 125 (the screen has not yet been restored to normal brightness). The controller 110 may further adjust the display data to reduce the grayscale value of any two adjacent pixels of the multiple pixels, so that the grayscale difference between any two adjacent pixels of the multiple pixels can be less than 50. In this way, the controller 110 can quickly and effectively restore the display panel 130 to display a display screen with normal brightness.

[0039] In summary, the display device and display method of the present invention can effectively reduce the discomfort caused to the user's eyes when the screen presents a completely white screen due to the explosion of a flash bomb in the game screen. In addition, the display device and display method of the present invention can automatically optimize the whitening effect presented by the display screen when the subsequent display screen has not yet recovered and presents a whitening screen, so that the user can react quickly and can quickly and normally perform subsequent game operations. In this regard, the display device and display method of the present invention can detect the grayscale value of the entire display screen and adjust the grayscale value according to different conditions to minimize the discomfort caused to the user's eyes by the flash bomb.
