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 white, causing discomfort to the user's eyes. Further, after the screen is displayed 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 is delayed.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The present invention provides a display device having adjustable gray scale values capable of providing an excellent display effect and a display method thereof.

Means for Solving the Problems

[0004] The display device having adjustable gray scale values of 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 assist 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 multiple grayscale values ​​of multiple pixels in the display screen are all first grayscale values, the controller reacts by adjusting the display data to lower the multiple grayscale values ​​of the multiple pixels to second grayscale values. The first grayscale value is greater than the second grayscale value.

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

[0007] In one embodiment of the present invention, when the controller detects that multiple grayscale values ​​of multiple pixels in the display screen are all greater than or equal to a first threshold, the controller reacts by adjusting the display data and dynamically lowering the multiple grayscale values.

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

[0009] In one embodiment of the present invention, when the controller detects that the grayscale difference between any two adjacent pixels in a display screen is greater than a second threshold, the controller reacts by adjusting the display data to lower the relatively larger of the two adjacent grayscale values ​​of the pixels so that the grayscale difference between any two adjacent pixels becomes less than a third threshold.

[0010] In one embodiment of the present invention, the first threshold described above is greater than the second and third thresholds, and the second threshold is greater than the third threshold.

[0011] In one embodiment of the present invention, the second threshold value described above 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 a controller. When the five-way key is triggered, the controller responds by performing a flashbang assist function.

[Effects of the Invention]

[0014] As described above, the display device and display method having adjustable grayscale values ​​of the present invention can automatically detect pixel changes on the display screen via the display device and automatically adjust the display data to provide an excellent display effect.

[0015] To make the above-mentioned features and advantages of the present invention easier to understand, embodiments are described below in detail in conjunction with the accompanying drawings. [Brief explanation of the drawing]

[0016] [Figure 1] This is a schematic diagram of a display device having an adjustable grayscale value according to one embodiment of the present invention. [Figure 2] This is a flowchart of a display method having an adjustable grayscale value according to one embodiment of the present invention. [Figure 3]This is a flowchart of a display method for another embodiment of the present invention. [Figure 4] This is a schematic diagram showing the changes in the display screen of one embodiment of the present invention. [Figure 5] This is a schematic diagram showing the changes in the display screen of one embodiment of the present invention. [Modes for carrying out the invention]

[0017] Herein, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numerals will be used in the drawings and the description to indicate the same or similar parts.

[0018] Figure 1 is a schematic diagram of a display device having an adjustable grayscale value in one embodiment of the present invention. Referring to 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 a computer host 200 via the communication interface 120. In this embodiment, the computer host 200 can execute a game program and provide the display device 100 with display data for the game screen, so that 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 game screens. In this embodiment, the display device 100 has a function that allows adjustment of the grayscale value.

[0019] In this embodiment, the controller 110 may include a display driver, memory, and associated control logic chips. The controller 110 can acquire display data (display signals) from the computer host 200 via the communication interface 120 and 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 to these.

[0020] Figure 2 is a flowchart of a display method having adjustable grayscale values ​​according to one embodiment of the present invention. Referring to Figures 1 and 2, the display device 100 can perform the following steps S210 to S240. In step S210, the display device 100 can receive display data of a display screen provided from the computer host 200 via the communication interface 120. In this embodiment, the above-mentioned display data is display data of a shooting game screen, but the present invention is not limited thereto. In step S220, when the controller 110 performs the flashbang assist function, the controller 110 can, in response, detect multiple grayscale values ​​of multiple pixels in the display screen. In this 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 can perform the flashbang assist function and automatically detect the display screen. The flashbang assist function refers to a function that enables the controller 110 to instantly detect the grayscale value of each pixel in the current display screen shown by the display panel 130. In one embodiment, the five-way key may be located on another input device (e.g., a keyboard or mouse) electrically connected to the display device 100 or the computer host 200. Furthermore, in another embodiment, the controller 110 can instantly detect the grayscale values ​​of multiple pixels in a portion of the current display screen shown by the display panel 130.

[0021] In step S230, when the controller 110 detects that all of the gray scale 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 a part of the plurality of gray scale 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 gray scale value referred to in the present invention refers to the luminance level displayed by a pixel. In the present embodiment, when the gray scale 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 grenade in the game, the controller 110 can automatically adjust the display data of the current (that is, the current frame) or the next display screen (that is, the next frame) to immediately lower the luminance of the current (that is, the current frame) or the next display screen (that is, the next frame). Therefore, it is not necessary 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 assist 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, in this 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. In this regard, 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 display like 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 any of the multiple grayscale values ​​are greater than or equal to a first threshold. If not, step S310 is executed again. If so, in step S350, the controller 110 can dynamically lower the multiple grayscale values. Specifically, in this embodiment, the first threshold may be 180, but the present invention is not limited thereto. When the controller 110 detects that any of the multiple grayscale values ​​of multiple pixels in the display screen are greater than or equal to 180, the controller 110 can adjust the display data to dynamically lower the multiple grayscale values. The controller 110 may lower them proportionally based on the magnitude of the grayscale values, or it may lower them using a lookup table, but the present invention is not limited thereto. Referring to Figure 5, which is a schematic diagram showing the changes in the display screen in one embodiment of the present invention. The display panel 130 can display the display screen 402 in the previous frame. If the display panel 130 is affected by a flash grenade in the game and may display as shown in the display screen 403 in the current frame, that is, if the screen brightness is too high (or if the screen has not yet returned to normal after the brightness has been reduced in step S330 above), 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 and dynamically lower multiple grayscale values. In this way, the controller 110 can quickly and effectively reduce or avoid situations where the display screen shown by the display panel 130 appears washed out.

[0026] In step S360, the controller 110 can detect whether the grayscale difference between any two adjacent pixels in the display screen is greater than the second threshold. If not, step S310 is performed again. If so, in step S370, the controller 110 can adjust the display data to lower the relatively larger of any two adjacent grayscale values ​​of the multiple pixels so that the grayscale difference between any two adjacent pixels is less than the third threshold. Specifically, in this embodiment, the first threshold is greater than the second and third thresholds, 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 grayscale difference across the entire display screen. Referring to Figure 5 in conjunction with this, the display panel 130 can display the display screen 402 in the previous frame. If the display panel 130 is affected by a flash grenade in the game and may display as shown in the display screen 403 in the current frame, that is, when the overall brightness of the display screen is still somewhat bright (or when the screen has not yet returned to normal after the brightness has been reduced in step S330 or step S350), the controller 110 can 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 returned to normal brightness). The controller 110 can further adjust the display data and lower the relatively larger 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 becomes 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.

[0027] As described above, the display device and display method of the present invention can effectively reduce the discomfort to the user's eyes when the screen turns completely white due to the explosion of a flashbang in the game screen. Furthermore, the display device and display method of the present invention can automatically optimize the whitish effect that appears on the display screen even when the display screen does not recover 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 display method of the present invention can minimize the discomfort to the user's eyes caused by a flashbang by detecting the grayscale value of the entire display screen and adjusting the grayscale value according to different conditions.
