Fig. 1 is the process flow diagram of a kind of backlight adjusting method according to an exemplary embodiment, and this backlight adjusting method is applied in terminal, and as shown in Figure 1, this backlight adjusting method comprises the following steps.
In a step 101, the backlight that in control screen, each subregion is corresponding sends the light of predetermined light intensity value.
Carry out piecemeal to the screen of liquid crystal display, the every block region obtained is called a subregion of screen.Wherein, each subregion corresponds to a backlight, and each backlight can regulate the light intensity value of its light sent.
In the present embodiment, can control the light that backlight corresponding to each subregion sends predetermined light intensity value, this predetermined light intensity value is the light intensity value according to actual conditions setting, such as, and the largest light intensity value that backlight can send.
In a step 102, actual light intensity values corresponding to each subregion is obtained by light sensor.

In step 103, if each actual light intensity values obtained not etc., does not then determine at least one the actual light intensity values except minimum actual light intensity values.
Minimum actual light intensity values refers to the light intensity value that in each actual light intensity values that light sensor obtains, light intensity value is minimum.
Because screen light leak causes extraneous light to enter screen, this makes the actual light intensity values of the subregion of light leak often be greater than the actual light intensity values of other lighttight subregion, therefore, need the actual light intensity values determining which subregion comparatively large, thus the light intensity value of the light that the backlight of these subregions sends is adjusted.
At step 104, control backlight corresponding at least one actual light intensity values and send the light being less than predetermined light intensity value, each actual light intensity values that light sensor is obtained again is equal.
In order to make the actual light intensity values of each subregion equal, needing to control backlight corresponding at least one actual light intensity values and sending the light being less than predetermined light intensity value.
In sum, the backlight adjusting method that the disclosure provides, sends the light of predetermined light intensity value by the backlight that each subregion in control screen is corresponding; Actual light intensity values corresponding to each subregion is obtained by light sensor; If each actual light intensity values obtained not etc., does not then determine at least one the actual light intensity values except minimum actual light intensity values; Control backlight corresponding at least one actual light intensity values and send the light being less than predetermined light intensity value, each actual light intensity values that light sensor is obtained again is equal, can when screen light leak causes the actual light intensity values of subregion larger, reduce the light intensity value of the light that backlight sends, thus reduce the actual light intensity values of subregion, make the actual light intensity values of each subregion equal, solve the problem because screen light leak causes liquid crystal display display effect not good, reach the object improving liquid crystal display display effect.
Fig. 2 is the process flow diagram of a kind of backlight adjusting method according to another exemplary embodiment, and this backlight adjusting method is applied in terminal, and as shown in Figure 2, this backlight adjusting method comprises the steps.
In step 201, when startup screen, screen shows pure color picture, the backlight that in control screen, each subregion is corresponding sends the light of largest light intensity value, and the largest light intensity value that each backlight is corresponding is identical.
Carry out piecemeal to the screen of liquid crystal display, the every block region obtained is called a subregion of screen.Such as, screen can be carried out piecemeal according to 4 × 4, obtain 16 subregions; Or, screen is carried out piecemeal according to 5 × 5, obtains 25 subregions.It should be noted that, when subregion is more, the light intensity value recorded each subregion is more accurate.
Wherein, the corresponding backlight of each subregion, and each backlight can regulate the light intensity value of its light sent.When screen light leak, extraneous light can enter screen, and cause the light intensity value of the subregion of light leak to increase, therefore, terminal can determine the subregion of light leak according to light intensity value.When determining the subregion of light leak, need to ensure that the light intensity value that each backlight sends is identical, that is, terminal needs to control the light that each subregion is corresponding in screen backlight sends predetermined light intensity value.
Wherein, the backlight that in control screen, each subregion is corresponding sends the light of predetermined light intensity value, comprising: when startup screen, screen shows pure color picture; The backlight that in control screen, each subregion is corresponding sends the light of largest light intensity value, and the largest light intensity value that each backlight is corresponding is identical.
In order to accurately determine the subregion of light leak, when startup screen, can show a pure color picture on screen, this pure color picture is the picture that color is single, makes the impact of this picture on the light intensity value of all subregions identical.In actual applications, pure color picture can be set to black picture.
Predetermined light intensity value is the light intensity value arranged according to actual conditions, such as, and the largest light intensity value that backlight can send.Certainly, predetermined light intensity value can be also other light intensity value, and the present embodiment is not construed as limiting.When predetermined light intensity value being set to the largest light intensity value that backlight can send, terminal can control the light that backlight corresponding to each subregion sends largest light intensity value, and each backlight corresponding largest light intensity value identical.
It should be noted that, backlight can adjust light intensity value by level.Such as, in terminal, be previously stored with the mapping table of light intensity progression and light intensity value, when backlight is adjusted to largest light intensity value by needs, only need backlight to adjust to maximum series.The quantity of the light intensity progression of backlight can set according to actual conditions, such as, the range of light intensity of the light sent of backlight can be divided into 4095 grades, the corresponding light intensity value of every one-level.
In step 202., actual light intensity values corresponding to each subregion is obtained by light sensor.
When show in screen be black picture and screen not light leak time, the light intensity value of the light that the backlight that the actual light intensity values of each subregion equals this subregion sends, namely actual light intensity values is predetermined light intensity value.When screen light leak, extraneous light can enter screen, and the light intensity value of the light that the backlight that the actual light intensity values of the subregion of light leak is not equal to this subregion sends, therefore, terminal also needs to obtain the actual light intensity values of each subregion.In the present embodiment, terminal can obtain the actual light intensity values of each subregion by light sensor.
Wherein, terminal can install a light sensor to subregion each in screen, or terminal can install a light sensor to each subregion of fringe region in screen, now, light sensor is positioned on the limit of the subregion corresponding with this light sensor and screen coincident.When some subregions and screen exist a limit overlap time, light sensor can be set on the limit of this coincidence; When some subregions and screen exist two limits overlap time, a limit can be selected arbitrarily in two limits overlapped, the limit selected arranges light sensor, also on two limits overlapped, all light sensor can be set, to improve the detection sensitivity to light intensity value.
The present embodiment, for the distribution of Mingguang City's line sensor on screen 4 × 4 subregions, please refer to the distribution schematic diagram of the light sensor shown in Fig. 3.In Fig. 3, screen divider is become 16 subregions by 4 × 4 subregions, these 16 subregions are numbered according to order from left to right, from top to bottom, then have 12 subregions to there is at least one limit to overlap with the limit of screen, the numbering of these 12 subregions is respectively 1,2,3,4,5,8,9,12,13,14,15,16.Because light sensor is positioned on the limit of subregion and screen coincident, and to there is a limit in the subregion being numbered 2,3,5,8,9,12,14,15 overlap respectively with the limit of screen, therefore, be numbered each corresponding light sensor of subregion of 2,3,5,8,9,12,14,15, the numbering of corresponding light sensor is b, c, o, f, n, g, k, j respectively.There are two limits respectively and overlap with the limit of screen in the subregion being numbered 1,4,13,16, now, any limit in the limit that can overlap each subregion two arranges a light sensor, that is, is numbered each corresponding light sensor of subregion of 1,4,13,16; Also a light sensor can be set on two of an each subregion limit overlapped, namely, be numbered each corresponding two light sensors of subregion of 1,4,13,16, the subregion reference numeral being numbered 1 is the light sensor of a and p, the subregion reference numeral being numbered 4 is the light sensor of d and e, the subregion reference numeral being numbered 13 is the light sensor of m and l, and the subregion reference numeral being numbered 16 is the light sensor of h and i.Be numbered the subregion of 6,7,10,11 not overlap with the limit of screen, therefore, the subregion being numbered 6,7,10,11 does not have corresponding light sensor.
In step 203, if each actual light intensity values obtained not etc., does not then determine at least one the actual light intensity values except minimum actual light intensity values.
Terminal can compare the size of actual light intensity values corresponding to each subregion of obtaining, if the equal and opposite in direction of actual light intensity values corresponding to each subregion obtained, then determines screen not light leak, process ends; If each actual light intensity values obtained not etc., does not then determine screen light leak.Because the actual light intensity values of the subregion of light leak is comparatively large, therefore, the subregion light leak corresponding to other actual light intensity values except minimum actual light intensity values can be determined.
In step 204, control backlight corresponding at least one actual light intensity values and send the light being less than predetermined light intensity value, each actual light intensity values that light sensor is obtained again is equal.

When reducing the light intensity value of the light that backlight sends, because the light leak situation of different subregions is different, therefore, need the adjustment light intensity value calculating this subregion according to the actual light intensity values of each subregion, when making backlight send light with this adjustment light intensity value, each actual light intensity values that light sensor obtains again is equal, this adjustment light intensity value be predetermined light intensity value is adjusted after the light intensity value that obtains.
In the present embodiment, control backlight corresponding at least one actual light intensity values and send the light being less than predetermined light intensity value, comprising:
1) for each actual light intensity values, calculate the difference that actual light intensity values deducts minimum actual light intensity values, the numerical value predetermined light intensity value being deducted difference is defined as adjusting light intensity value;
2) control the backlight corresponding with actual light intensity values and send the light adjusting light intensity value.
Due to the actual light intensity values that minimum actual light intensity values is lighttight subregion, therefore, terminal needs the actual light intensity values of each subregion to adjust to this minimum actual light intensity values.Such as, the actual light intensity values determined can be deducted minimum actual light intensity values by terminal, the difference obtained is defined as the light intensity value that backlight needs the light reduced, more predetermined light intensity value is deducted this difference, be adjusted light intensity value.
For the ease of understanding, the present embodiment will with predetermined light intensity value for largest light intensity value, and for 4 × 4 subregions, above-mentioned method of adjustment is described, then suppose that light sensor acquires and be numbered 2, 3, 4, 5, 8, 9, 12, 13, 14, 15, the actual light intensity values of the subregion of 16 is m, m that is to say minimum actual light intensity values, and the actual light intensity values being numbered the subregion of 1 is p (p > m), now can determine the subregion light leak being numbered 1, backlight corresponding to subregion being numbered 1 needs the light intensity value of the light reduced to be p-m, suppose that largest light intensity value is L, the adjustment light intensity value that then can calculate the subregion being numbered 1 is L-(p-m), backlight corresponding to subregion controlling to be numbered 1 sends the light of L-(p-m), the actual light intensity values that light sensor can be made again to obtain the subregion being numbered 1 is m, thus make the actual light intensity values of all subregions equal.Wherein, backlight corresponding to subregion controlling to be numbered 1 sends the light of L-(p-m), can find the light intensity progression corresponding with light intensity value L-(p-m) in the mapping table, adjust backlight and send light corresponding to this progression.
In sum, the backlight adjusting method that the disclosure provides, sends the light of predetermined light intensity value by the backlight that each subregion in control screen is corresponding; Actual light intensity values corresponding to each subregion is obtained by light sensor; If each actual light intensity values obtained not etc., does not then determine at least one the actual light intensity values except minimum actual light intensity values; Control backlight corresponding at least one actual light intensity values and send the light being less than predetermined light intensity value, each actual light intensity values that light sensor is obtained again is equal, can when screen light leak causes the actual light intensity values of subregion larger, reduce the light intensity value of the light that backlight sends, thus reduce the actual light intensity values of subregion, make the actual light intensity values of each subregion equal, solve the problem because screen light leak causes liquid crystal display display effect not good, reach the object improving liquid crystal display display effect.
