Below in conjunction with accompanying drawing, the embodiment of the present application technical scheme is described in detail.
A kind of method that regulates display unit backlight illumination is provided in the application's embodiment, be applied in an electronic equipment, as shown in Figure 1, this electronic equipment comprises first main body 10 with first surface 101 and second 102, the second main body 20 of the 3rd 201 and fourth face 202, wherein, this first main body 10 is rotatably connected with this second main body 20, has display unit 30 at this second 102 Shang She Ge.
As shown in Figure 2, the method comprises:
S10, in the time that the backlight brightness values of described display unit 30 is the first value, the angle detecting between obtaining described second 102 and described the 3rd 201 is the first angle;
S20, at least based on described the first angle, adjusts to second value different from described the first value by described backlight brightness values from described the first value.
Wherein, in S10, in the time that the backlight brightness values of display unit 30 is the first value, the angle detecting between obtaining described second 102 and described the 3rd 201 is the first angle, specifically comprises: the angle detecting between described second 102 and described the 3rd 201 by the angular transducer in described electronic equipment is the first angle.
In concrete implementation process, this electronic equipment is specifically as follows notebook computer or other electronic equipment, as moving DVD player etc., in the embodiment of the present application, by taking notebook computer as example, the concrete technical scheme to this programme realizes and being described in detail.
In the time that electronic equipment is notebook computer, this notebook computer comprises first main body 10 with first surface 101 and second 102, the second main body 20 of the 3rd 201 and fourth face 202, wherein, this first main body 10 is rotatably connected with this second main body 20, there is display unit 30 at this second 102 Shang She Ge, and at the 3rd 201 Shang She Ge keyboards, the Shu Ru Zhuan Ge such as Trackpad, Hui She Ge notebook computer mainboard in the second main body 20, on mainboard, Hui She Ge realizes the various hardware of notebook computer function including CPU, and between the first main body 10 and the second main body 20, to realize connection by rotating shaft, and then realization between the first main body 10 and the second main body 20 is rotatably connected.
This angular transducer Ke Yi She Ge is in the rotating shaft of this notebook.By this angular transducer, just can calculate now this one side and this angulation of keyboard of notebook computer display screen.
Angle between the angular transducer by this electronic equipment detects second 102 and the 3rd 201 is the first angle, specifically comprises:
Step 1, when described the first main body 10 is during with the relative rotation of described the second main body 20, generates one and detects instruction;
Step 2, passes to described angular transducer by described detection instruction;
Step 3, described angular transducer detects with described the 3rd 201 angulations described second 102 based on described detection instruction, obtains described the first angle.
In concrete implementation process, the display screen of notebook computer can rotate to form different angles by rotating shaft relatively with the keyboard face of notebook, first, when the display screen of this notebook is in the time that this keyboard face rotates relatively, just function that can open detection angle, thereby generate the instruction of a detection angles, this notebook computer can pass to the angular transducer being positioned on rotating shaft by the instruction of this detection angles, this angular transducer just can start to detect the display screen of this notebook computer and keyboard face angulation in the time of steady state (SS), angulation.For example, when this one side of the display screen of notebook computer and keyboard are 90 while spending for this angulation knocking, what this angular transducer just became with keyboard based on this display screen 90 spends, and obtains this angle information.
After obtaining angle information, carry out S20, at least based on described the first angle, described backlight brightness values is adjusted to second value different from described the first value from described the first value.
Wherein, in this step, can adjust the backlight brightness values of electronic equipment according to two kinds of situations.
In the first situation, only need to adjust the backlight brightness values of electronic equipment according to angle information.
In the second situation, need to adjust the backlight brightness values of electronic equipment according to angle and the light intensity of injecting electronic equipment.
In the first situation, first to judge that described the first angle is whether within the scope of first threshold; In the time that described the first angle is within the scope of described first threshold, based on described the first angle, described backlight illumination is adjusted to described the second value from described the first value.
In concrete embodiment, still be described in detail as an example of notebook computer example, due in the first situation, the angle of notebook display screen and keyboard face is within the scope of this first threshold, within the scope of this first threshold time, the photosensitive sensor being positioned on notebook display screen is difficult to the illumination that senses that external environment is stronger, therefore, only need to adjust the backlight intensity of display screen according to the angle information of notebook display screen and keyboard face.
This first threshold scope can be for the face that the knocks angulation of this note-book computer display screen and keyboard be within the scope of one that is less than 90 degree.Because the angle of the face that knocks of notebook display screen and keyboard is less than 90 while spending, ambient light is injected the photosensitive sensor that the light of display screen is difficult to be positioned on display screen and is detected, and, when this angle is little cannot watch display screen to user time, can directly computer display screen curtain backlight illumination be now transferred to the most weak state, so, within the angle of notebook display screen and keyboard is less than the certain limit of 90 degree, only need to adjust the backlight intensity of display screen according to the size of angle.
For example, when the display screen of notebook computer and keyboard face angulation are 45 while spending, now, user has been difficult to watch the display screen of computer, the backlight intensity of display screen need to be adjusted; When the display screen of notebook computer and keyboard face angulation are 70 while spending, now, although can see the display screen of computer, but, due to the photosensitive sensor on notebook display screen to external world surround lighting inject the light of display screen insensitive, now, just according to note-book computer display screen and keyboard face angulation information, the backlight illumination of the display screen of notebook is now regulated.
In the time that backlight intensity is adjusted, described backlight brightness values is adjusted to described the second value from described the first value, specifically comprise: described backlight brightness values is adjusted to described second value lower than described the first value from described the first value, or described backlight brightness values is adjusted to described second value higher than described the first value from described the first value.
The mode of this adjusting has multiple.
Regulative mode one, if current notebook backlight brightness values is brill at 20L(L), the angle information now detecting is 70 degree, so, notebook backlight brightness values is now carried out to 120% compensation, and the notebook backlight illumination after regulating is so 24L; If current notebook backlight brightness values is 14L, the angle information now detecting is 45 degree, so notebook backlight brightness values is now carried out to 50% weakening, notebook backlight brightness values after regulating is so 7L, now this notebook computer display screen is in dormant state, user also, without watching screen, has reached the object of power saving.
Regulative mode two, if current notebook backlight brightness values at 30L, now detects that notebook display screen and keyboard face angulation information are 70 degree, so, brings up to 36L to notebook backlight brightness values now; If current notebook backlight brightness values is 12L, now detect that notebook display screen and the keyboard face angulation value of information are 30 degree, so, notebook backlight brightness values is now impaired to 6L or notebook backlight illumination is now shown as to blank screen state, like this, more save electricity.
In the second situation, first, judge that the first angle is whether within the scope of Second Threshold; In the time that described the first angle is within the scope of described Second Threshold, based on described the first angle, the brightness value that obtains the external environment light of described display unit under described the first angle is the 3rd value; Then,, based on described the first angle and described the 3rd value, described backlight illumination is adjusted to described the second value from described the first value.
In concrete embodiment, this second situation, namely the angle of this notebook display screen and keyboard face is in Second Threshold scope, and now, the photosensitive sensor being arranged on this display screen can sense the illumination that external environment is stronger.For example, Second Threshold scope can be for the face that the knocks angulation of this note-book computer display screen and keyboard in the scope of 90-180 degree time, because the angle of the face that knocks of notebook display screen and keyboard is after being greater than 90 degree, along with the increase of angle; establish the photosensitive sensor of Ge on display screen in the situation that extraneous surround lighting is certain, the external environment light sensing can strengthen gradually.
Again such as, the current notebook display screen being detected by angular transducer and keyboard face angulation are 90 degree, according to this angle information, the intensity of illumination that the external environment light obtaining is injected computer display screen is 40L, and detect that external environment light intensity is 60L, need the illumination brightness value of the computer display screen to injecting to adjust, now, in order to adapt to the demand of user with eye, just intensity of illumination now need to be improved.
If the notebook display screen being detected by angular transducer current and keyboard face angulation are 120 degree, according to angle information, the intensity of illumination that the external environment light obtaining is injected computer display screen is 50L, and external environment light intensity is 60L, at this moment, also need the illumination intensity value of the computer display screen to injecting to adjust, specifically in order to adapt to external environment light intensity, need now computer backlight brightness values to improve.
Wherein, backlight brightness values is adjusted to described the second value from described the first value, this adjustment specifically comprises:
When described the 3rd value is when lower than default external environment brightness values, described the first value is strengthened, and described backlight brightness values is adjusted to second value higher than described the first value from described the first value.
When described external environment brightness values, weakens described the first value, and described backlight brightness values is adjusted to second value lower than described the first value from described the first value when low than described the first value.
This adjustment can or weaken for compensation adjustment to be adjusted.
One, compensation adjustment, as described in above-mentioned example, when the angle of notebook display screen and keyboard face is 90 degree, and when the intensity of illumination that external environment light is injected notebook display screen is 40L, and the intensity of illumination of external environment is 60L, the intensity of illumination 40L that surround lighting is injected notebook display screen to external world compensates, for example, can compensate 120% light,, after compensation, the backlight illumination of notebook display screen is adjusted into 48L.
If the angle of current notebook display screen and keyboard is 100 degree, the intensity of illumination that external environment light is injected notebook display screen is 45L, now the intensity of illumination of external environment is 60L, the intensity of illumination 45L that surround lighting is injected notebook display screen to external world compensates, for example, can compensate 110% light,, after compensation, the backlight illumination of notebook display screen is adjusted into 49.5L.
Two, weaken and adjust, if when the residing external environment of current notebook is darker environment, for example, it is around unglazed environment, and notebook now residing backlight brightness values be 40L, and detect that notebook display screen and keyboard face angulation information are 90 degree, in order to alleviate because surrounding environment is darker, and notebook display screen is brighter, there is the defect that user's eyes is caused to damage, be original 50% by the brightness adjustment of notebook display screen now, the backlight brightness values obtaining after adjusting is 20L, to adapt to user's viewing effect.
If when the residing external environment of current notebook is darker environment, and notebook now residing backlight brightness values be 40L, and detect that notebook display screen and keyboard face angulation information are 100 degree, in order to alleviate because surrounding environment is darker, and notebook display screen is brighter, under this darker environment, user's eyes are had to damage, now, be the information of 100 degree according to this angle, be original backlight illumination by the brightness adjustment of notebook display screen 30%, the backlight brightness values obtaining after adjusting is 12L, thereby adapts to user's best viewing effect.
According to above-mentioned adjustment, in the time that the display screen of notebook and keyboard face angulation are within the scope of first threshold, the backlight brightness values of this notebook display screen can be heightened also and can be turned down; When the display screen of notebook and keyboard face angulation are during in Second Threshold scope, the backlight brightness values of notebook display screen both can be heightened also and can be turned down, because notebook display screen and keyboard face angulation value are when the Second Threshold scope, when external environment is high light environment simultaneously, the illumination brightness meeting of injecting this notebook display screen strengthens along with the increase of angle, under the environment strengthening gradually in brightness, the backlight illumination of notebook display screen is also needed to strengthen gradually, to adapt to extraneous high light environment; In the time that external environment is low light environment, because this notebook display screen can only sense that environment is now low light environment, so, now just need to adjust the backlight illumination of display screen according to the angle of notebook display screen and keyboard face.
Obtaining angle information, or the backlight intensity of the display screen to notebook after acquisition angle information and external environment optical information is adjusted, first be that brightness value to adjusting to first calculates, thereby obtain the brightness value after calculating, then, system can be based on after calculating brightness value, by this brightness value from described the first value the second value described in adjusting to.
