It is more extensive.
Fig. 6 is a kind of flow chart of display brightness method of adjustment according to another exemplary embodiment, such as Fig. 6 institutes
Show, optionally, step S12 includes：
In step S61, current environment brightness is detected；
In step S62, when current environment brightness is less than or equal to predetermined luminance value, GTG change is carried out to pixel
Change, obtain grey decision-making after the conversion of pixel.
In alternative, only when ambient brightness is less than to a certain degree, such as when ambient brightness is less than or equal to
During 0.1lux, GTG adjustment just is carried out to display interface, avoids continually adjusting the GTG of display interface, section according to ambient brightness
About terminal processing capacity and power consumption, user experience are preferable.
As shown in figs. 7 a and 7b, the GTG numerical value of highlights substantially reduces, and the transmitance of such backlight will decline, overall
Brightness will substantially reduce, the contrast of picture can also reduce.Among low-light level environment, contrast reduces the shadow to image quality
Ring and little, so being sufficient for the requirement of user.
Among the processor (such as AP video-stream processor or DDIC) of display, a series of look-up table is set, led to
Corresponding look-up table is crossed, realizes and converts original luma data, which is specifically called organize look-up table, can be according to ambient light
Brightness automatically selects, or manually selects.Look-up table is set of number, and content is different and different according to the bit digits of GTG,
Shown if GTG is 8bit, grey decision-making is between 0~255 after the original gray-scale value of look-up table and conversion；If GTG is
10bit is shown, then grey decision-making is between 0~1023 after the original gray-scale value of look-up table and conversion.
As shown in figure 8, such as original gray-scale value is A straight lines, if selected for B curves as look-up table, then data are worked as
In 255 grey decision-makings become 175, now the 256th of look-up table unit should be just (175/255) * 255；150 GTGs become
90, then numeral is exactly (90/150) * 255 corresponding to 150 GTGs among look-up table.Look-up table is all to 28 powers or 2
10 powers do normalized.
Fig. 9 is a kind of flow chart of display brightness method of adjustment according to another exemplary embodiment, such as Fig. 9 institutes
Show, optionally, this method also includes：
In step S91, the brightness value of environment is detected；
In step S92, screen display brightness value is adjusted according to ambient brightness value；
In step S93, the relation of present intensity value and setting value after screen adjustment is judged；
In step S94, when judging present intensity value less than the first setting brightness, first kind grey decision-making is adjusted；
In step S95, when judging present intensity value higher than the second setting brightness, the second class grey decision-making is adjusted.
When ambient brightness is relatively low, terminal can automatically adjust the display brightness of screen first, but the screen after adjusting shows
Show brightness for a user, in this case it is still possible to it is still very bright, also, after user opens some application programs, on screen
Display brightness is still returned to the brightness before brightness regulation, and so, Consumer's Experience is poor.In alternative, in screen
After brightness regulation, the brightness to diverse location on screen judges again, and different ashes is carried out for the part of different brightness
Degree regulation, as shown in Figure 7a, the top half grey decision-making of screen is larger, and brightness is relatively low, it may not be necessary to GTG adjustment is carried out again,
The latter half GTG of screen is smaller, and brightness is higher, can only adjust the latter half of screen.So so that no matter at which kind of
In the case of, the brightness of screen display interface can be effectively reduced, and reach the purpose of protection screen user's eyesight.
Figure 10 is a kind of flow chart of display brightness method of adjustment according to another exemplary embodiment, such as Figure 10 institutes
Show, optionally, described to obtain in display interface before the original gray-scale value of pixel, methods described also includes：
In step S101, the brightness value of the pixel in display interface is detected；
In step s 102, whether the brightness value of pixel exceedes setting brightness value in the interface for judging to detect；
In step s 103, when judging to exceed setting brightness value, it is determined that the institute of the pixel more than setting brightness value
In positional information；
In step S104, adjustment determines the grey decision-making of the pixel of position.
In alternative, the GTG that pixel is carried out according to the brightness of each pixel on screen adjusts, so, can be with
The brightness of screen display interface is more quickly and accurately reduced, reaches the purpose of protection screen user's eyesight.
Figure 11 is a kind of flow chart of display brightness method of adjustment according to another exemplary embodiment, such as Figure 11 institutes
Show, optionally, methods described also includes：
In step S111, the color gamut space value of screen display is obtained；
In step S112, according to the color gamut space value got, the grey decision-making of each pixel in display interface is adjusted.
In alternative, certain table color pattern institute of the color gamut space value, i.e. screen of screen display is also further obtained
Numerical value corresponding to the range areas that the number of colors that can be expressed is formed, for different color gamut spaces, using different GTGs
Adjustment.So so that the adjustment to screen intensity more conforms to the performance of screen, and the effect of brightness adjustment is more preferable, protects user
Eyesight.
Figure 12 is a kind of flow chart of display brightness method of adjustment according to another exemplary embodiment, such as Figure 12 institutes
Show, optionally, this method also includes：
In step S121, establish corresponding each pixel and set pair of different groups of the input grey decision-making with exporting grey decision-making
Should be related to, corresponding relation for input grey decision-making and the output grey decision-making ratio as the size of gray value is into nonlinear change
Or linear change, input grey decision-making are not less than 1 with exporting the ratio of grey decision-making；
In step S122, when getting screen brightness value higher than setting brightness, screen display circle is adjusted according to ratio
The output gray level value of the pixel in face.
In alternative, the corresponding relation of GTG adjustment can be pre-established, the grey decision-making of screen is greater than after adjustment
The grey decision-making of forth screen is adjusted, so so that the luminance-reduction of screen after adjustment, to protect user's eyesight.
The present embodiment, among the environment of extremely low brightness, display system is exported extremely low brightness, reduce to eyes
Injury, suitable for the low-light level environment of no lighting apparatus.
Also, it is all effective to all display contents, without being limited to some application program, so, without answering each
Corresponding Night is all individually developed with degree, reduces the size of resource file, saves memory space, and it is simple to operate,
Better user experience.
