Technical Field

[0001] The present invention relates to display technology, and more particularly, to a display device and a display method having adjustable gray-scale values.

Background Art

[0002] When a user is hit by a flashbang during a shooting game, the screen instantly turns completely white, causing discomfort to the user's eyes. Further, after the screen is displayed completely white, the screen becomes slightly whitish for a certain period of time and then gradually returns to the original normal game screen. Therefore, the user's reaction to the game becomes slower.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The present invention provides a display device having adjustable gray-scale values that can provide an excellent display effect and a display method thereof.

Means for Solving the Problems

[0004] The display device having adjustable gray-scale values according to the present invention includes a display panel, a communication interface, and a controller. The communication interface is used to receive display data of the 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 based on the display data. When the controller executes the flashbang assistance function, in response thereto, the controller analyzes the display data and detects a plurality of gray-scale values of a plurality of pixels in the display screen. When the controller detects that all of the plurality of gray-scale values of the plurality of pixels in the display screen are greater than or equal to a first threshold value, in response thereto, the controller adjusts the display data and lowers at least a part of the plurality of gray-scale values.

[0005] In one embodiment of the present invention, when the controller detects that all of the grayscale values of a plurality of pixels in the display screen are the first grayscale value, in response, the controller adjusts the display data and reduces the grayscale values of the plurality of pixels to a second grayscale value. The first grayscale value is greater than the second grayscale value.

[0006] In one embodiment of the present invention, the above-described first grayscale value is 255, and the second grayscale value is 125.

[0007] In one embodiment of the present invention, when the controller detects that all of the grayscale values of a plurality of pixels in the display screen are greater than or equal to a first threshold value, in response, the controller adjusts the display data and dynamically reduces the plurality of grayscale values.

[0008] In one embodiment of the present invention, the above-described first threshold value is 180.

[0009] In one embodiment of the present invention, when the controller detects that the difference between any two adjacent grayscale values of a plurality of pixels in the display screen is greater than a second threshold value, in response, the controller adjusts the display data and reduces the relatively larger of any two adjacent grayscale values of the plurality of pixels so that the difference between any two adjacent grayscale values of the plurality of pixels is less than a third threshold value.

[0010] In one embodiment of the present invention, the above-described 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.

[0011] In one embodiment of the present invention, the above-described second threshold value is 125, and the third threshold value is 50.

[0012] In one embodiment of the present invention, the above-described display device further includes a five-way key. The five-way key is electrically connected to the controller. When the five-way key is triggered, in response thereto, the controller executes a flash bomb assistance function.

[0013] The display method having an adjustable gray scale value of the present invention includes the steps of receiving display data of a display screen via a communication interface, and when the controller executes a flash bomb assistance function, in response thereto, analyzing the display data via the controller and detecting a plurality of gray scale values of a plurality of pixels in the display screen, and when the controller detects that all of the plurality of gray scale values of the plurality of pixels in the display screen are equal to or greater than a first threshold value, in response thereto, adjusting the display data via the controller and lowering at least a part of the plurality of gray scale values, and driving a display panel to display an adjusted display screen based on the adjusted display data via the controller.

Embodiments for Carrying Out the Invention

[0017] Here, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. As much as possible, the same component reference numerals are used in the drawings and the description to indicate the same or similar parts.

[0018] FIG. 1 is a schematic diagram of a display device having adjustable grayscale values in one embodiment of the present invention. Referring to FIG. 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 a computer host 200 via the communication interface 120. In this embodiment, since the computer host 200 can execute a game program and provide display data of a game screen to the display device 100, the display device 100 can display a corresponding display screen via the display panel 130 based on the display data. However, the present invention is not limited to a game screen. In this embodiment, the display device 100 has a function of adjusting grayscale values.

[0019] In this embodiment, the controller 110 can include a display driver, a memory, and related control logic chips. The controller 110 can obtain display data (display signals) from the computer host 200 via the communication interface 120, adjust the display data, and 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, etc., but the present invention is not limited thereto.

[0020] FIG. 2 is a flowchart of a display method having adjustable grayscale values according to an embodiment of the present invention. Referring to FIGS. 1 and 2, the display device 100 can execute the following steps S210 to S240. In step S210, the display device 100 can receive the display data of the display screen provided from the computer host 200 via the communication interface 120. In this embodiment, the above-described display data is the display data of the shooting game screen, but the present invention is not limited thereto. In step S220, when the controller 110 executes the flash bomb assistance function, in response thereto, the controller 110 can detect the grayscale values of a plurality of pixels in the display screen. In this embodiment, the display device 100 can 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 can execute the flash bomb assistance function and automatically detect the display screen. The flash bomb assistance function refers to a function in which the controller 110 can instantaneously 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 be installed on the display device 100 or another input device (for example, a keyboard or a mouse) electrically connected to the computer host 200. Further, in another embodiment, the controller 110 can instantaneously detect the grayscale values of a plurality of pixels in a part of the region in the current display screen displayed by the display panel 130.

[0021] In step S230, when the controller 110 detects that all of the grayscale values of a plurality of pixels within the display screen that the display panel 130 is about to display are greater than or equal to a first threshold value, in response, the controller 110 can adjust the display data to lower at least some of the plurality of grayscale values. In step S240, the controller 110 can drive the display panel 130 to display an adjusted display screen based on the adjusted display data. It should be noted that the grayscale value referred to in the present invention refers to the luminance level displayed by a pixel. In the present embodiment, when the grayscale values of a plurality of pixels of the current display screen that the display panel 130 is about to display suddenly increase (that is, when the luminance of the screen becomes high, the screen is too bright, or the entire screen becomes white) due to the influence of a flash bomb in the game, the controller 110 can automatically adjust the display data of the current (i.e., the current frame) or the next display screen (i.e., the next frame) to immediately lower the luminance of the current (i.e., the current frame) or the next display screen (i.e., the next frame). Therefore, there is no need for the game program to wait until the luminance is lowered. Thus, the display device 100 of the present 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 via the controller 110. The luminance adjustment operation of the screen adjusted by the display device 100 is not notified to the computer host 200. That is, the display device 100 does not affect or change the data output by the game program itself.

[0022] FIG. 3 is a flowchart of a display method according to another embodiment of the present invention. Referring to FIGS. 1 and 2, the display device 100 can execute the following steps S310 to S370. Note that steps S320, S340, and S360 can be executed simultaneously or in order.

[0023] In step S310, the controller 110 can execute the flashbang assistance function and detect the grayscale values of a plurality of pixels in the display screen displayed by the display panel 130. In step S320, the controller 110 can detect whether the plurality of grayscale values are the first grayscale value. If not, step S310 is executed again. If so, in step S330, the controller 110 can lower the plurality of grayscale values to a second grayscale value.

[0024] Specifically described, in the present embodiment, when the controller 110 detects that all of the grayscale values of a plurality of pixels in the display screen are the first grayscale value, the controller 110 can adjust the display data and lower the grayscale values of the plurality of pixels to a second grayscale value. Here, 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. Regarding this, referring to FIG. 4, FIG. 4 is a schematic diagram showing a change in the display screen of one embodiment of the present invention. The display panel 130 can display the display screen 401 in the previous frame. When the display panel 130 may be displayed as the display screen 402 in the current frame under the influence of a flashbang in the game, that is, when the screen becomes whitish (pure 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 lower the grayscale values of a plurality of pixels of the display screen 402 or the next display screen, and quickly or rapidly lower the brightness of the display screen.

[0025] In step S340, the controller 110 can detect whether all of the plurality of grayscale values are greater than or equal to the first threshold value. If not, step S310 is executed again. If so, in step S350, the controller 110 can dynamically lower the plurality of grayscale values. Specifically described, in the present embodiment, the first threshold value may be 180, but the present invention is not limited thereto. When the controller 110 detects that all of the grayscale values of the plurality of pixels in the display screen are greater than or equal to 180, the controller 110 can adjust the display data and dynamically lower the plurality of grayscale values. The controller 110 may lower it proportionally based on the magnitude of the grayscale value, or may lower it using a look-up table, but the present invention is not limited thereto. In this regard, referring to FIG. 5, FIG. 5 is a schematic diagram showing a change in the display screen of one embodiment of the present invention. The display panel 130 can display the display screen 402 in the previous frame. When the display panel 130 may be displayed like the display screen 403 in the current frame under the influence of a flash grenade in the game, that is, when the brightness of the screen is too high (or when it has not yet returned to a normal screen even after the brightness is lowered in step S330 above), the controller 110 can detect that all of the grayscale values of the pixels of the display screen 402 displayed by the display panel 130 are greater than or equal to 180. The controller 110 can adjust the display data and dynamically lower the plurality of grayscale values. In this way, the controller 110 can quickly and effectively reduce or avoid the situation where the display screen displayed by the display panel 130 becomes whitish.

[0026] In step S360, the controller 110 can detect whether the gray-scale difference between any two adjacent pixels among a plurality of pixels within the display screen is greater than a second threshold. If not, step S310 is executed again. If so, in step S370, the controller 110 can adjust the display data to lower the gray-scale value of the relatively larger one of any two adjacent pixels among the plurality of pixels, so that the gray-scale difference between any two adjacent pixels among the plurality of pixels is smaller than a third threshold. Specifically described, in the present embodiment, the first threshold is greater than the second threshold and the third threshold, and the second threshold is greater than the third threshold. The second threshold is 125, and the third threshold is 50, but the present invention is not limited thereto. The controller 110 can reduce the gray-scale difference across the entire display screen. In this regard, referring also to FIG. 5, the display panel 130 can display the display screen 402 in the previous frame. When the display panel 130 may be displayed like the display screen 403 in the current frame under the influence of a flash grenade in the game, that is, when the overall brightness of the display screen is still slightly bright (or in a situation where the brightness has not yet returned to a normal screen even after the brightness is reduced in step S330 or step S35 above), the controller 110 can detect that the gray-scale difference between any two adjacent pixels among the plurality of pixels of the display screen 402 displayed by the display panel 130 is greater than 125 (the screen has not yet returned to normal brightness). The controller 110 can further adjust the display data to lower the gray-scale value of the relatively larger one of any two adjacent pixels among the plurality of pixels, so that the gray-scale difference between any two adjacent pixels among the plurality of pixels is smaller than 50. In this way, the controller 110 can quickly and effectively restore the display panel 130 and display a display screen with normal brightness.

[0027] As described above, the display device and the display method of the present invention can effectively reduce the discomfort given to the user's eyes when the screen turns completely white due to the explosion of a flash bomb within the game screen. Furthermore, the display device and the display method of the present invention can automatically optimize the whitish effect that appears on the display screen in a situation where the display screen does not recover afterwards and remains whitish, so that the user can react quickly and perform subsequent game operations quickly and normally. In this regard, the display device and the 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, thereby minimizing the discomfort given to the user's eyes by the flash bomb.
