Furthermore, for users such as e-sports players, in addition to response speed, display brightness (luminance) and contrast must also be taken into consideration.

[0003] Different LCD devices perform differently in low light, especially in dark scenes in games.

[0020] FIG. 1 is a block diagram of a scene brightness adjustment computer according to the present embodiment. The scene brightness adjustment computer (hereinafter simply referred to as “computer 100 ”) includes a power unit 110 , a display device 120 , a storage unit 130 , a processing unit 140 , and a detection unit 150 .

[0021] The computer 100 may be a desktop PC, a notebook PC, a mobile communication device, a tablet PC, or the like.

[0022] The processing unit 140 is connected to the power unit 110, the display device 120, and the storage unit .

[0023] The power unit 110 provides power for the operation of the processing unit 140, the display device 120, and the storage unit .

[0024] The processing unit 140 can send a control command 163 to the power unit 110 to adjust the operating current 162 of the backlight unit 122 .

[0025] The type of display device 120 may be, but is not limited to, an IPS panel (In-Plane Switching), a PLS panel (Plane-to-Line), a VA panel (Vertical Alignment), or a TN panel (Twisted Nematic).

[0026] The display device 120 further includes a logic unit 121 and a backlight unit 122 .

[0027] The detection unit 150 is connected to the processing unit 140 , the logic unit 121 and the backlight unit 122 .

[0028] The logic unit 121 controls the rotation amount of the liquid crystal to adjust the display color or brightness (transmittance) of each area of ​​the display device 120. The backlight unit 122 is used to provide the overall brightness of the display device 120.

[0029] The power unit 110 is connected to the logic unit 121 and the backlight unit 122, respectively, and supplies power for the operation of the logic unit 121 and the backlight unit 122, respectively.

[0030] The detection unit 150 is connected between the power unit 110 and the logic unit 121. The detection unit 150 acquires a logic current value 161 when the logic unit 121 is operating.

[0031] The detection section 150 outputs the logic current value 161 to the processing unit 140 . The power unit 110 supplies an operating current 162 to the backlight unit 122 .

[0032] The storage unit 130 stores a monitoring program 131 , a plurality of application programs 132 , and a lookup table 133 .

[0033] The lookup table 133 records a number of application scenes for each application program 132 .

[0034] As shown in FIG. 2, each application scene corresponds to a default scene current value 164 and a target brightness current 165 .

[0035] In the case of a game application program 132, the game may provide multiple different application scenes, each with a corresponding display intensity.

[0036] Display device 120 outputs different scene luminances for different application scenes. Therefore, the logic unit 121 needs to control the correction of the liquid crystal.

[0037] Thus, different scene intensities correspond to different actuation currents 162 to match each scene intensity. This operating current 162 is referred to as the default scene current value 164 .

[0038] Since the brightness difference to be adjusted varies for each scene, this adjusted brightness difference is called a target brightness, and the corresponding adjusted brightness is called a target brightness current 165; see FIG. In other words, each application scene corresponds to its own target luminance current 165 .

[0039] When the processing unit 140 executes the application program 132 , the processing unit 140 periodically obtains the logic current value 161 from the detection unit 150 .

[0040] The processing unit 140 determines whether to adjust the brightness of the display device 120 based on the logic current value 161 . FIG. 3 shows a flowchart for the processing unit 140 to determine and adjust the brightness of the display device 120, which includes the following steps:

[0041] Step S310: The computer executes the application program to obtain the current scene. Step S320: The computer obtains the logic current value of the logic unit of the display device. Step S330: The computer searches a lookup table according to the current scene or logic current value to select a target brightness current. The lookup table stores multiple scene information of the application program. Each scene information corresponds to a default scene current value and a target brightness current. Step S340: The computer provides a target luminance current to the backlight unit of the display device.

[0042] First, the processing unit 140 executes the monitoring program 131 . The monitoring program 131 may be an independent application program 132 or may be a system program incorporated into an operating system.

[0043] When the application program 132 is executed, the monitoring program 131 can obtain the application program 132 through the operating system.

[0044] The monitoring program 131 compares the acquired application program 132 with the lookup table 133 .

[0045] If the acquired application program 132 does not exist in the lookup table 133 , the monitoring program 131 does not execute the associated process of searching and selecting the target luminance current 165 .

[0046] When the acquired application program 132 exists in the lookup table 133 , the monitoring program 131 can periodically acquire the application scene and its logic current value 161 from the detection unit 150 .

[0047] The monitoring program 131 can identify the current application scene based on the change in the display color of the application program 132 .

[0048] Generally speaking, when a game program displays a scene in a darker environment, in addition to the overall pixel changes of the display device 120 being uniform, the color values ​​of the pixels also mostly fall within the values ​​of the dark areas.

[0049] Taking a three-primary color system as an example, the distribution of pixels in a dark scene falls between RGB(0,0,0) and RGB(20,20,20).

[0050] In addition, the monitoring program 131 can also obtain the execution status of the application program 132 through the operating system to determine the content of the application scene of the application program 132 .

[0051] Alternatively, the monitoring program 131 determines the application scene through modification of the hardware information, driver, or register of the display card.

[0052] When the processing unit 140 executes the application program 132 , the monitoring program 131 acquires the logic current value 161 of the logic unit 121 during the execution of the application program 132 .

[0053] When the color of the pixels in the application scene fits the distribution described above, the monitoring program 131 determines that the application scene is the current scene. The monitoring program 131 obtains the logic current value 161 of the current scene.

[0054] As shown in FIG. 2, the monitoring program 131 searches the lookup table 133 based on the current scene or logic current value 161 and selects the corresponding target luminance current 165 .

[0055] The processing unit 140 sends a new control command 163 to the power unit 110 to cause the power unit 110 to change the operating current 162 to the selected target brightness current 165 and supply it to the backlight unit 122 to increase the brightness of the backlight unit 122.

[0056] In this embodiment, the monitoring program 131 searches the lookup table 133 based on the current scene, and obtains the corresponding application scene and the associated default scene current value 164 from the lookup table 133 .

[0057] Next, the monitoring program 131 determines whether the logic current value 161 matches the default scene current value 164 .

[0058] When the logic current value 161 does not match the default scene current value 164, the processing unit 140 selects a target luminance current 165 and drives the power unit 110 to provide the selected target luminance current 165 to the backlight unit 122.

[0059] The processing unit 140 provides matching conditions corresponding to the logic current values ​​161 and the default scene current values ​​164 based on different types of display devices 120 .

[0060] When the display device 120 is an IPS panel, a PLS panel, or a VA panel, the logic current value 161 is defined as being less than the default scene current value 164 and thus mismatched.

[0061] When a voltage is applied to an IPS panel, a PLS panel, or a VA panel, the amount of light passing through the liquid crystal panel of the backlight unit 122 is increased, thereby increasing the brightness of the screen of the display device 120.

[0062] Therefore, when no voltage is applied to the IPS panel, PLS panel, or VA panel, the screen of the display device 120 appears completely black.

[0063] Conversely, when the screen of display device 120 is completely white, logic current value 161 of logic unit 121 is at its maximum.

[0064] The monitoring program 131 can further determine the brightness or darkness state of the display device 120 based on the logic current value 161 of the logic unit 121 .

[0065] When the logic current value 161 does not match the default scene current value 164 , the target brightness current 165 is greater than the logic current value 161 .

[0066] The monitoring program 131 selects a target luminance current 165 , and the power unit 110 provides the target luminance current 165 to the backlight unit 122 , thereby increasing the amount of light emitted by the backlight unit 122 .

[0067] As the brightness of the backlight unit 122 increases, the brightness of the entire display device 120 also increases.

[0068] Taking Fig. 4 as an example, the upper part of Fig. 4 shows the curve of the operating current 162 of the backlight unit 122 versus time. The lower part of Fig. 4 shows the curve of the logic current value 161 of the logic unit 121 versus time. Assume that the processing unit 140 acquires a current scene at time T1.

[0069] The processing unit 140 searches the lookup table 133 based on the current scene, and obtains the corresponding default scene current value 164 and target brightness current 165 at time T2.

[0070] At time T1 in FIG. 4, processing unit 140 determines that logic current value 161 is less than default scene current value 164.

[0071] This is because in the case of an IPS panel, a PLS panel, or a VA panel, the logic current value 161 is smaller than the default scene current value 164 and is considered to be inconsistent. Therefore, processing unit 140 determines that the application scene for display device 120 is a "dark scene."

[0072] After the processing unit 140 obtains the target luminance current 165 , the power unit 110 is modified to provide the target luminance current 165 to the backlight unit 122 .

[0073] If the display device 120 is a TN panel, the logic current value 161 is greater than the default scene current value 164, which is defined as a mismatch.

[0074] After applying a voltage to the TN panel, the logic unit 121 blocks the light passing through the backlight unit 122. This reduces the overall brightness of the display device 120.

[0075] Therefore, if the logic current value 161 is greater than the default scene current value 164, it is called a mismatch. If the logic current value 161 does not match the default scene current value 164, the monitoring program 131 obtains the corresponding target luminance current 165 based on the current scene.

[0076] In other words, if the logic current value 161 does not match the default scene current value 164 , the target brightness current 165 will be less than the logic current value 161 .

[0077] The power unit 110 supplies the selected target brightness current 165 to the backlight unit 122 to increase the amount of light emitted by the backlight unit 122 . Therefore, the display device 120 can increase the overall brightness without adjusting the logic unit 121.

[0078] In this embodiment, the monitoring program 131 periodically acquires the logic current value 161 . For this reason, the monitoring program 131 temporarily stores these logic current values ​​161 in the storage unit 130 .

[0079] When the monitoring program 131 acquires the current logic current value 161, it loads the previously acquired logic current value 161 and calculates the difference between the current current value and the previously acquired logic current value 161, thereby obtaining the amount of change in current. The monitoring program 131 determines whether the amount of change in current is greater than a threshold value.

[0080] If the amount of change in current is greater than the threshold, the monitoring program 131 determines that the brightness of the current scene has become a "dark scene." Therefore, the monitoring program 131 uses the current logic current value 161 to look up the corresponding default scene current value 164 and target brightness current 165 in the lookup table 133 .

[0081] The monitoring program 131 drives the power unit 110 based on the retrieved target luminance current 165 , so that the power unit 110 supplies the target luminance current 165 to the backlight unit 122 of the display device 120 .

[0082] Since the new target luminance current 165 is higher than the original current value, the light emission luminance of the backlight unit 122 increases, and the screen luminance of the display device 120 improves.

[0083] When the application scene is changed again, the monitoring program 131 also executes step S320 to obtain the logic current value 161. The monitoring program 131 determines whether the new application scene is brighter, darker, or unchanged.

[0084] When the new application scene becomes brighter, the monitoring program 131 can adjust the target brightness current 165 back to the original operating current 162 .

[0085] The monitoring program 131 reduces the brightness of the backlight unit 122, so that the display brightness of the display device 120 is reduced to suit the new application scene. Therefore, the user does not need to manually adjust the brightness of the display device 120.

[0086] In this embodiment, the computer 100 further includes a processing method for establishing the relevant information in the lookup table 133 .

[0087] As shown in FIG. 5, the computer 100 includes a power unit 110, a display device 120, a storage unit 130, and a processing unit 140.

[0088] The display device 120 further includes a logic unit 121 and a backlight unit 122. The storage unit 130 further includes a look-up table 133, an application program 132, and a table creation program 134.

[0089] In this embodiment, the lookup table 133 further records panel attributes, including panel category, panel size, panel resolution, refresh rate, response time, color gamut range, or connection interface.

[0090] The panel attribute is an IPS panel, a PLS panel, a VA panel, or a TN panel.

[0091] The connection interface may be, but is not limited to, a High Definition Multimedia Interface (HDMI) interface series, a DisplayPort interface, or an embedded DisplayPort (eDP) interface.

[0092] The processing unit 140 executes the table generation program 134 to generate a current value corresponding to the brightness of each scene in the look-up table 133 .

[0093] See Figure 6. The method for creating and adjusting scene luminance with table creation program 134 includes the following steps.

[0094] Step S610: The computer obtains the panel attributes of the display device; Step S620: The computer obtains the logic current value of the display device in the application scene where the application program is running; Step S630: Adjust the brightness of the display device to the target brightness, and the computer obtains the target brightness current of the target brightness; and Step S640: The computer records the logic current value and the target brightness current in a look-up table according to the application scene.

[0095] First, the processing unit 140 executes the table creation program 134 . The table creation program 134 can obtain the panel attributes of the display device 120 via the operating system or the Basic Input / Output System (BIOS).

[0096] The table creation program 134 records the panel attributes in the lookup table 133 .

[0097] The processing unit 140 executes the application program 132 . The table creation program 134 acquires the logic current value 161 of the display device 120 while the application program 132 is running. At the same time, the table creating program 134 can record the corresponding logic current values ​​161 according to different application scenarios.

[0098] The recorded logic current value 161 is the default scene current value 164 . In other words, each application scene has a correspondingly recorded default scene current value 164 .

[0099] Next, the table creation program 134 increases the brightness of the backlight unit 122 until the display device 120 reaches the target brightness. The target luminance is determined by a tester or color calibrator.

[0100] The table creation program 134 obtains the drive current value of the backlight unit 122 based on the target luminance, and records the obtained current value in the target luminance current 165 field of the lookup table 133 .

[0101] The table creation program 134 records the default luminance current values ​​(corresponding to the default scene current values ​​164 described above) and the target luminance currents 165 for different application scenes.

[0102] Take a laptop for example, the laptop has an eDP interface, a 15-inch IPS panel, a resolution of 1920x1080, and a refresh rate of 240Hz.

[0103] In the eDP interface, pins 36 to 39 (BL_PWR) are used to control the brightness of the backlight unit 122, and pins 18 to 21 (LCD_VCC) are used by the logic unit 121 to control the rotation of the liquid crystal.

[0104] As mentioned above, when the screen is completely black, the IPS panel does not need to rotate the LCD, and the logic current value 161 to operate is the lowest. Conversely, when the screen is completely white, the logic current value 161 to be activated is the highest.

[0105] The table creation program 134 can also provide a number of different display screens (corresponding to application scenes).

[0106] For example, a black and white mosaic pattern or a three-color checkerboard pattern is used as a standard for the distribution of the logic current value 161.

[0107] The laptop runs various application programs 132 for games such as Diablo® IV and The Witcher 3.

[0108] The table creation program 134 obtains logic current values ​​161 according to the daytime and nighttime scenes of the game, and lists the logic current values ​​161 of the above-mentioned application scenes as follows:

[0109] TIFF0007763286000001.tif59154Table 1. Comparison of logic current values ​​by application scenario

[0110] The table creation program 134 can record the corresponding current values ​​in the lookup table 133 based on the aforementioned scenes. Furthermore, the table creation program 134 can obtain the difference between the daytime and nighttime of the application program 132, and the table creation program 134 records the difference in the amount of change in current in the lookup table 133.

[0111] The above-described computer 100 for adjusting scene brightness and the method for adjusting scene brightness automatically adjust the brightness of the computer 100 in various application scenes. Therefore, the user does not need to manually set the brightness and contrast of the display device 120 or the driver, respectively.

[0112] Then, after the scene of the application program 132 changes, the computer 100 can also adjust the brightness to match the brightness of the corresponding application scene. Therefore, the user does not need to take time to adjust the settings of the display device 120, reducing the inconvenience. [Explanation of symbols]
