Description

显示器亮度调整方法Display Brightness Adjustment Method

技术领域technical field

本发明是关于一种显示器亮度调整方法，且特别是关于可借由改变显示器亮度调整曲线以提供使用者所需显示器亮度的显示器亮度调整方法。The present invention relates to a display brightness adjustment method, and in particular to the display brightness adjustment method which can provide the display brightness required by the user by changing the display brightness adjustment curve.

背景技术Background technique

一般显示器具有光感测组件，用以自动调整显示屏幕与周遭环境的亮度差异，其目的是为了避免因两者明暗差异过大，而造成使用者的眼睛疲累不适。A general display has a light-sensing component to automatically adjust the brightness difference between the display screen and the surrounding environment. The purpose is to avoid eye fatigue and discomfort caused by the excessive difference between the brightness and darkness of the two.

请参照图1，其所示为传统显示器光感测组件的亮度调整曲线图。传统的显示器是根据显示器亮度调整曲线S提供使用者选用数种预设的显示器亮度变化范围，例如是低亮度工作区(暗)、中亮度工作区(中)以及高亮度工作区(亮)三种亮度显示区域。在低亮度工作区操作下，当环境亮度超过极限值Le1时，显示器亮度即固定在Lm1值，在中亮度工作区操作下，当环境亮度超过极限值Le2时，显示器亮度即固定在Lm2值，而在高亮度工作区操作下，当环境亮度超过极限值Le3时，显示器亮度即固定在Lm3值，其中环境亮度极限值Le1＜Le2＜Le3，且显示器亮度值Lm1＜Lm2＜Lm3。Please refer to FIG. 1 , which shows a brightness adjustment curve of a conventional display light sensing component. The traditional display is based on the display brightness adjustment curve S to provide users with several preset display brightness change ranges, such as low-brightness work area (dark), medium-brightness work area (medium) and high-brightness work area (bright). A brightness display area. In the low-brightness working area, when the ambient brightness exceeds the limit value Le1, the display brightness is fixed at the Lm1 value; in the medium-brightness working area, when the ambient brightness exceeds the limit value Le2, the display brightness is fixed at the Lm2 value, In the high-brightness working area, when the ambient brightness exceeds the limit value Le3, the display brightness is fixed at the value of Lm3, where the ambient brightness limit value Le1<Le2<Le3, and the display brightness value Lm1<Lm2<Lm3.

然而，传统的显示器仅能提供几种预设的亮度显示区域以及亮度极限值，而无法依照当时环境明暗及使用者的需求来分别调整亮度显示区域及定义显示器亮度调整曲线，大大降低使用者对显示器亮度的选择性。However, traditional displays can only provide several preset brightness display areas and brightness limit values, and cannot separately adjust the brightness display area and define the display brightness adjustment curve according to the current environment and user needs, which greatly reduces the user's confidence in the brightness. Selectivity of display brightness.

具体实施方式Detailed ways

请同时参照图2及图4。图2示出依照本发明一优选实施例的一种显示器亮度调整方法流程图。图4示出依照本发明一优选实施例的显示器亮度调整曲线的调整示意图。首先，在步骤210中，显示器会利用光感测组件，例如是光敏电阻传感器，检测当时的环境亮度Le0，例如是100流明，并根据预设显示器亮度调整曲线S1，以决定显示器的亮度Lm0，例如是90流明。预设显示器亮度调整曲线S1例如是记录于控制器的查阅表(Lookup Table)中。接着，在步骤220中，以屏幕直接显示(On-screen Display，OSD)方式显示一调整选单，提供使用者决定是否调整显示器的亮度。若使用者选择不调整显示器亮度，则显示器即利用预设显示器亮度调整曲线S1，并根据光感测组件所检测到当时的环境亮度来提供其显示亮度。若使用者选择调整显示器亮度，例如将显示器亮度调低至Lm1，例如80流明，则显示器会根据使用者所需的显示器亮度(80流明)，及当时光感测组件检测到的环境亮度，例如还是原先的环境亮度Le0，来得出自订显示器亮度调整曲线S2。最后，显示器利用光感测组件检测环境亮度，并根据自订显示器亮度调整曲线S2，以决定显示器的亮度。因此，显示器可依照使用者所需的显示器亮度，提供自订的显示器亮度调整曲线，提高使用者调整显示器亮度的便利性及多样性。Please refer to Figure 2 and Figure 4 at the same time. Fig. 2 shows a flowchart of a method for adjusting brightness of a display according to a preferred embodiment of the present invention. FIG. 4 shows a schematic diagram of adjusting the brightness adjustment curve of a display according to a preferred embodiment of the present invention. First, in step 210, the display will use a light sensing component, such as a photoresistor sensor, to detect the ambient brightness Le0 at that time, such as 100 lumens, and adjust the curve S1 according to the preset display brightness to determine the brightness Lm0 of the display. For example 90 lumens. The preset display brightness adjustment curve S1 is, for example, recorded in a lookup table (Lookup Table) of the controller. Next, in step 220, an adjustment menu is displayed in an On-screen Display (OSD) manner, allowing the user to decide whether to adjust the brightness of the display. If the user chooses not to adjust the display brightness, the display uses the preset display brightness adjustment curve S1 to provide display brightness according to the current ambient brightness detected by the light sensing component. If the user chooses to adjust the brightness of the display, such as lowering the brightness of the display to Lm1, such as 80 lumens, the display will be based on the user's desired display brightness (80 lumens) and the ambient brightness detected by the light sensing component, such as Still the original ambient brightness Le0 is used to derive the custom display brightness adjustment curve S2. Finally, the display uses the light sensing component to detect the ambient brightness, and adjusts the curve S2 according to the customized display brightness to determine the brightness of the display. Therefore, the display can provide a self-defined display brightness adjustment curve according to the display brightness required by the user, thereby improving the convenience and diversity of the user's adjustment of the display brightness.

请同时参照图3及图4。图3示出依照本发明一优选实施例的一种显示器亮度调整方法详细流程图。在步骤210之前，显示器亮度调整方法还包括判断显示器的亮度调整功能是否被启动(如步骤200所示)，若否，则结束本方法。若是，则进行上述的步骤210以及步骤220。另外，步骤220还包括步骤230、232、234及236。在步骤230中，以屏幕直接显示(On-screenDisplay，OSD)方式显示一调整选单，提供使用者决定是否调整显示器的亮度。若否，则回到步骤210。若是，则继续步骤232，当使用者选择将显示器亮度调低至Lm1，例如是80流明时，显示器会判断显示器亮度调整比率Rm(＝(Lm0-Lm1)/Lm0)是否超过光传感器的亮度误差范围，例如是±5％。若显示器亮度调整比率Rm在亮度误差范围内，则表示显示器无法分辨Lm1与原先显示器亮度值Lm0与光传感器的亮度误差对外界环境变化的差异，因此，回到步骤210，利用预设显示器亮度调整曲线S1，并根据当时环境亮度来提供显示器亮度。若显示器亮度调整比率Rm超过亮度误差范围，例如Rm＝(Lm0-Lm1)/Lm0＝(90-80)/90＝11％，已超过误差范围的5％。因此，继续步骤234，利用光感测组件检测得到稳定的环境亮度Le0。此时，显示器会再利用光感测组件检测当时的环境亮度，一直到得到稳定的环境亮度为止，例如是100流明的环境亮度Le0。Please refer to Figure 3 and Figure 4 at the same time. Fig. 3 shows a detailed flowchart of a method for adjusting brightness of a display according to a preferred embodiment of the present invention. Before step 210, the display brightness adjustment method further includes judging whether the brightness adjustment function of the display is activated (as shown in step 200), if not, the method ends. If yes, proceed to the above step 210 and step 220 . In addition, step 220 further includes steps 230 , 232 , 234 and 236 . In step 230 , an adjustment menu is displayed in an On-screen Display (OSD) manner for the user to decide whether to adjust the brightness of the display. If not, go back to step 210 . If so, continue to step 232. When the user chooses to lower the brightness of the display to Lm1, for example, 80 lumens, the display will determine whether the display brightness adjustment ratio Rm (=(Lm0-Lm1)/Lm0) exceeds the brightness error of the light sensor The range is, for example, ±5%. If the brightness adjustment ratio Rm of the display is within the brightness error range, it means that the display cannot distinguish the difference between Lm1, the original brightness value Lm0 of the display, and the brightness error of the light sensor due to changes in the external environment. Therefore, go back to step 210 and use the preset display brightness adjustment Curve S1, and provide display brightness according to the ambient brightness at that time. If the display brightness adjustment ratio Rm exceeds the brightness error range, for example, Rm=(Lm0-Lm1)/Lm0=(90-80)/90=11%, it has exceeded 5% of the error range. Therefore, continue to step 234, using the light sensing component to detect and obtain a stable ambient brightness Le0. At this time, the display will use the light sensing component to detect the current ambient brightness until a stable ambient brightness is obtained, for example, the ambient brightness Le0 of 100 lumens.

接着，在步骤236中，显示器根据使用者选择的显示器亮度(Lm1)及当时稳定的环境亮度(Le0)，以得出自订显示器亮度调整曲线。例如是图4所示，利用(Le0，Lm1)以及亮度调整曲线S1的坐标原点(0，0)来计算产生自订显示器亮度调整曲线S2。本发明亦可以曲线补给(curve feeding)的方式来产生上述的自订显示器亮度调整曲线。Next, in step 236, the display obtains a custom display brightness adjustment curve according to the display brightness (Lm1) selected by the user and the current stable ambient brightness (Le0). For example, as shown in FIG. 4 , (Le0, Lm1) and the coordinate origin (0, 0) of the brightness adjustment curve S1 are used to calculate and generate a custom display brightness adjustment curve S2. The present invention can also generate the above-mentioned customized display brightness adjustment curve by means of curve feeding.

再者，在步骤242中，当显示器依使用者所需得出自订显示器亮度调整曲线S2时，显示器可将此亮度调整曲线S2的数据记录于显示器内控制器的查阅表中，以更新预设显示器亮度调整曲线S1。最后，在步骤244中，显示器利用光感测组件检测环境亮度，并根据控制器记录的自订显示器亮度调整曲线S2，以决定显示器的亮度，并继续步骤200，判断显示器的亮度调整功能是否依然启动。若是，则重复步骤210；若亮度调整功能被关闭，则结束本方法，而记录于查阅表的显示器亮度调整曲线S2为下次显示器亮度调整功能启动后的预设显示器亮度调整曲线。Furthermore, in step 242, when the display obtains the custom display brightness adjustment curve S2 according to the user's needs, the display can record the data of the brightness adjustment curve S2 in the look-up table of the controller in the display to update the default Display brightness adjustment curve S1. Finally, in step 244, the display uses the light sensing component to detect the ambient brightness, and determines the brightness of the display according to the custom display brightness adjustment curve S2 recorded by the controller, and proceeds to step 200 to determine whether the brightness adjustment function of the display is still active. start up. If yes, repeat step 210; if the brightness adjustment function is disabled, the method ends, and the display brightness adjustment curve S2 recorded in the look-up table is the default display brightness adjustment curve after the display brightness adjustment function is activated next time.

本发明上述实施例所公开的一种显示器亮度调整方法，可根据使用者所需的显示器亮度，及当时光感测组件检测到的环境亮度，来得出自订显示器亮度调整曲线。因此，本发明可让使用者自订显示器亮度，并不受限于传统预设的几个亮度显示区域以及对应的显示器亮度极限值。可完全依照当时环境明暗及使用者本身的喜好及需求来做最适当的设定，提高显示器亮度的动态调整及多样性。The display brightness adjustment method disclosed in the above-mentioned embodiments of the present invention can obtain a customized display brightness adjustment curve according to the display brightness required by the user and the ambient brightness detected by the light sensing component at the time. Therefore, the present invention allows the user to customize the brightness of the display, and is not limited to several traditionally preset brightness display areas and the corresponding limit values of the brightness of the display. The most appropriate setting can be made completely according to the light and shade of the environment at that time and the user's own preferences and needs, and the dynamic adjustment and diversity of the brightness of the display can be improved.

综上所述，虽然本发明已以一优选实施例公开如上，然其并非用以限定本发明，任何业内人士，在不脱离本发明的精神和范围内，当可作各种的更动与润饰，因此本发明的保护范围当视后附的权利要求书所界定者为准。In summary, although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention.
