Mode for Carrying Out the Invention

[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 130.

[0023] The power unit 110 supplies power for the operations of the processing unit 140, the display device 120, and the storage unit 130.

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

[0025] The type of the 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 region 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 respective operations of the logic unit 121 and the backlight unit 122.

[0030] The detection unit 150 is connected between the power unit 110 and the logic unit 121. The detection unit 150 obtains a logic current value 161 during the operation of the logic unit 121.

[0031] The detection unit 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 look-up table 133.

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

[0034] As shown in FIG. 2, each application scene matches the default scene current value 164 and the target luminance current 165.

[0035] In the case of the game application program 132, the game can provide a plurality of different application scenes, and each application scene has a corresponding display luminance.

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

[0037] Therefore, different scene luminances match different operating currents 162 so as to match each scene luminance. This operating current 162 is referred to as the default scene current value 164.

[0038] Since the luminance differences to be adjusted for each scene are also different, this adjusted luminance difference is referred to as the target luminance, and the luminance adjusted correspondingly is referred to as the target luminance current 165. Please refer to FIG. 2. In other words, each application scene matches its own target luminance current 165.

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

[0040] The processing unit 140 determines whether to adjust the luminance 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 luminance of the display device 120, which includes the following steps.

[0041] Step S310: The computer executes an 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 look-up table based on the current scene or the logic current value and selects a target luminance current. Multiple scene information of the application program is recorded in the look-up table. Each scene information matches the default scene current value and the target luminance current. Step S340: The computer provides the 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 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 via the operating system.

[0044] The monitoring program 131 compares the obtained application program 132 with the look-up table 133.

[0045] When the obtained application program 132 does not exist in the look-up table 133, the monitoring program 131 does not execute the related process of searching and selecting the target luminance current 165.

[0046] When the obtained application program 132 exists in the look-up table 133, the monitoring program 131 can periodically obtain 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 change of the display device 120 becoming uniform, most of the pixel color values also fall within the values of the dark area.

[0049] Taking the 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] Furthermore, the monitoring program 131 can also obtain the execution state of the application program 132 through the operating system and determine the content of the application scene of the application program 132.

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

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

[0053] When the color of the pixels in the application scene conforms to the aforementioned distribution, 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 look-up table 133 based on the current scene or the logic current value 161, and selects the corresponding target luminance current 165.

[0055] The processing unit 140 transmits a new control command 163 to the power unit 110, causes the power unit 110 to change the operating current 162 to the selected target luminance current 165, and supplies it to the backlight unit 122 to increase the luminance of the backlight unit 122.

[0056] In this embodiment, the monitoring program 131 searches the look-up table 133 based on the current scene, and obtains the corresponding application scene and the default scene current value 164 belonging to the look-up 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 the 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 a matching condition corresponding to the logic current value 161 and the default scene current value 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 smaller than the default scene current value 164 and inconsistent.

[0061] The IPS panel, the PLS panel, and the VA panel increase the amount of light passing through the liquid crystal panel of the backlight unit 122 by applying a voltage to increase the luminance of the screen of the display device 120.

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

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

[0064] The monitoring program 131 can further determine the brightness state or the 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 the target brightness current 165, and the power unit 110 provides the target brightness 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 is a curve showing the change in the operating current 162 of the backlight unit 122 over time. The lower part of FIG. 4 shows the curve of the change in the logic current value 161 of the logic unit 121 over time. Assume that the processing unit 140 acquires the current scene at time T1.

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

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

[0071] 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 regarded as inconsistent. Therefore, the processing unit 140 determines that the application scene of the display device 120 is a "dark scene".

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

[0073] When the display device 120 is a TN panel, the logic current value 161 is larger than the default scene current value 164 and is defined as inconsistent.

[0074] After applying a voltage to the TN panel, the logic unit 121 blocks the light passing through the backlight unit 122. As a result, the overall luminance of the display device 120 decreases.

[0075] For this reason, when the logic current value 161 is larger than the default scene current value 164, it is called inconsistent. When 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, when the logic current value 161 does not match the default scene current value 164, the target luminance current 165 is smaller than the logic current value 161.

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

[0078] In this embodiment, the monitoring program 131 periodically acquires the logic current value 161. Therefore, 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 performs a difference operation with the current current value to obtain the current change amount. The monitoring program 131 determines whether the current change amount is greater than the threshold value.

[0080] If the current change amount is greater than the threshold value, 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 search for the corresponding default scene current value 164 and the target luminance current 165 in the look-up table 133.

[0081] The monitoring program 131 drives the power unit 110 based on the searched target luminance current 165, and the power unit 110 is made to supply 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 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 acquire the logic current value 161. The monitoring program 131 determines whether the new application scene has become brighter, darker, or has not changed.

[0084] When a new application scene brightens, the monitoring program 131 can adjust the target luminance current 165 to the original operating current 162.

[0085] The monitoring program 131 reduces the luminance of the backlight unit 122, and as a result, the display luminance of the display device 120 decreases to match 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 related information of the look-up table 133.

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

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

[0089] In this embodiment, the look-up table 133 further records panel attributes. The panel attributes include 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 (registered trademark)) interface series, a DisplayPort interface, or an Embedded DisplayPort (eDP) interface.

[0092] The processing unit 140 executes a table creation program 134 to create in the look-up table 133 current values corresponding to the luminance of each scene.

[0093] Please refer to FIG. 6. The method of creating and adjusting the luminance of a scene in the table creation program 134 includes the following steps.

[0094] Step S610: The computer acquires the panel attributes of the display device; Step S620: The computer acquires the logic current value of the display device in the application scene where the application program operates; Step S630: Adjust the luminance of the display device to the target luminance, and the computer acquires the target luminance current of the target luminance; and Step S640: The computer records the logic current value and the target luminance current in the look-up table based on the application scene.

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

[0096] The table creation program 134 records the panel attributes in the look-up table 133.

[0097] The processing unit 140 executes the application program 132. During the execution of the application program 132, the table creation program 134 acquires the logic current value 161 of the display device 120. At the same time, the table creation program 134 can record the corresponding logic current value 161 based on different application scenes.

[0098] The recorded logic current value 161 is the default scene current value 164. In other words, each application scene correspondingly records the 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 brightness is determined by a tester or a color calibrator.

[0100] Based on the target brightness, the table creation program 134 acquires the drive current value of the backlight unit 122 and records the obtained current value in the column of the target brightness current 165 in the lookup table 133.

[0101] The table creation program 134 records the default brightness current value (corresponding to the aforementioned default scene current value 164) and the target brightness current 165 for different application scenes.

[0102] Taking a notebook PC as an example, for instance, the notebook PC is equipped with an eDP interface, a 15-inch IPS panel, a resolution of 1920×1080, and a refresh rate of 240Hz.

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

[0104] As described above, in the case where the screen of the IPS panel is entirely black, the logic current value 161 for operation, which does not require rotating the liquid crystal, is the lowest. Conversely, when the screen is entirely white, the logic current value 161 for operation is the highest.

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

[0106] For example, a black-and-white checkered pattern (Mosaic Pattern) or a checkered pattern of the three primary colors is used as a reference for the distribution of the logic current value 161.

[0107] The notebook PC executes various application programs 132 such as Diablo (registered trademark) IV and The Witcher 3.

[0108] The table creation program 134 acquires the logic current value 161 according to the day and night scenes of the game, and enumerates the logic current value 161 of the above-mentioned application scenes as follows.

[0109] TIFF2025096101000002.tif59154 Table 1. Comparison table of logic current values by application scene

[0110] The table creation program 134 can record the corresponding current value in the lookup table 133 based on the above-mentioned scenes. In addition, the table creation program 134 can obtain the difference between day and night of the application program 132, and the table creation program 134 records the above difference in the amount of current change in the lookup table 133.

[0111] The computer 100 and the scene brightness adjustment method for adjusting the above-mentioned 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] After the scene of the application program 132 changes, the computer 100 can also adjust the brightness so as to match the brightness of the corresponding application scene. Therefore, the time required for the user to adjust the setting value of the display device 120 is not needed, and the annoyance is reduced.
