Referring to fig. 2, an embodiment of a screen brightness adjusting method according to the present invention is provided, where the screen brightness adjusting method includes:
step S10, dividing the screen display area into several subareas;
because there are various directions in the direction of the light of inciding to the screen, consequently can judge more meticulously with the screen subregion that the light is incited from specific which position of screen, from the effect, the screen subregion is more the regulation of luminance more accurate, in addition because current screen all comprises a plurality of accuse light areas, and every accuse light area can both the independent control luminance moreover, consequently is favorable to the luminance of accurate regulation screen with the screen subregion, solves the reflection of light problem.
Specifically, each partition comprises at least one unit light control area, wherein one screen is composed of a plurality of light control areas, and each light control area can be used for independently adjusting the brightness. And the brightness of each subarea is uniformly adjusted by adjusting the brightness of the unit light control area. Referring to fig. 8 and 9, fig. 8 is a schematic diagram of distribution of light control areas of a screen, as can be seen from fig. 8, the screen is composed of 64 light control areas and includes 8 rows and 8 columns of light control areas, fig. 9 is a schematic diagram of partitions of the screen, and the screen is totally divided into 16 partitions, that is, one partition includes 4 light control areas.
Step S20, obtaining the environment brightness of the position of a plurality of subareas, wherein the plurality of subareas at least comprise 4 subareas distributed in different directions of the screen;
because light can be at least from the screen of the southeast northwest incident of screen, consequently a plurality of subregion have 4 at the not equidirectional subregion of screen of distribution at least, then can ensure to obtain the ambient brightness of the not equidirectional position to be favorable to judging the incident direction of light.
In addition, in this embodiment, the ambient brightness of the positions where the plurality of partitions are located may be obtained by the light sensor, and the ambient brightness of the positions where the plurality of partitions are located may also be obtained by the luminance meter.
Step S30, calculating the average value of the environmental brightness of the positions of the plurality of partitions;
the average value of the ambient brightness of the positions of the plurality of partitions is calculated according to the brightness data, for example, if the ambient brightness of the positions of 16 partitions is obtained, the average value of the ambient brightness of the positions of 16 partitions is calculated, and the rest of the partitions without the brightness data are not counted.
Step S40, comparing the ambient brightness of the position of each partition in the plurality of partitions with the average value respectively to obtain the difference value between the ambient brightness of the position of each partition in the plurality of partitions and the average value respectively;
after the average value is calculated, the ambient brightness of the position of each partition in the plurality of partitions is respectively compared with the average value, and because the ambient brightness of the position of the partition on the light incidence side of the screen in a certain direction is the largest in difference value with the average value and the ambient brightness of the position of the partition on the light emission side of the screen in the direction is the smallest in difference value with the average value if light is incident on the screen from the certain direction.
In step S50, the brightness of each of the plurality of partitions is adjusted according to the difference between the ambient brightness of the location of each of the plurality of partitions and the average value.
As can be seen from step S40, if the difference between the ambient brightness at the position of the partition located at the light incident side of the direction of the screen and the average value is the largest, and the difference between the ambient brightness at the position of the partition located at the light emitting side of the direction of the screen and the average value is the smallest, the brightness of the partition located at the light incident side of the direction of the screen and the brightness of the partition located at the light emitting side of the direction of the screen can be adjusted, specifically, if the difference between the ambient brightness at the position of the partition and the average value is large, the brightness of the partition is adjusted to be bright, and if the difference between the ambient brightness at the position of the partition and the average value is small, the brightness of the partition is adjusted to be dark, so that the brightness of the screen corresponds to the ambient brightness, and the technical problem of light reflection of the existing display screen is solved.
Referring to fig. 3, an embodiment of a screen brightness adjusting method according to the present invention is provided, where the screen brightness adjusting method includes:
the plurality of partitions at least comprise all partitions bordering the screen frame in the screen;
step 50 comprises:
and step 52, adjusting the brightness of each partition according to the difference value between the ambient brightness of the position where each partition bordering the screen frame is located and the average value.
Because the subareas bordering the screen frame are respectively distributed in different directions of the screen, the direction of the incident light can be known by acquiring the ambient brightness of the position of the subarea bordering the screen frame and according to the difference between the ambient brightness of the position of each subarea bordering the screen frame and the average value, and the direction of the incident light is the subarea with a large difference between the ambient brightness of the position and the average value and a small difference between the ambient brightness of the position of the subarea and the average value. That is, it is known that the ambient brightness of the screen is weakened from the direction of the incident light, correspondingly, if the difference between the ambient brightness at the location of the partition bordering on the screen frame and the average value is large, the brightness of the partition is lightened, if the difference between the ambient brightness at the location of the partition bordering on the screen frame and the average value is small, the brightness of the partition is lightened, and in addition, the brightness of the partition of the screen along the direction of the incident light is weakened from the strength, so that the brightness of the screen corresponds to the ambient brightness, thereby realizing the precise adjustment of the screen reflection.
Further, based on the above embodiment, please refer to fig. 4, which shows an embodiment of the screen brightness adjusting method of the present invention, wherein step S10 includes:
step S12, the screen display area is divided into a plurality of square partitions with equal area by a plurality of vertical lines and a plurality of horizontal lines interlaced with each other.
The screen display area is divided into a plurality of square partitions in an equal-area mode through the longitudinal lines and the transverse lines, the shape of each partition is regular square, and due to the fact that the partitions are of the square structure in the equal-area mode, when light rays are divided from each partition bordering on a screen frame, the partitions on the screen are divided more, and the incident direction of the light rays is located more accurately.
Referring to fig. 9, specifically, the number of the longitudinal lines and the transverse lines is 4; the number of partitions is 16. The 4 vertical lines and horizontal lines are criss-crossed to divide the screen into 16 partitions.

Specifically, in the embodiment, the light ray sensor is arranged at the intersection angle which is on the partition boundary and intersects with the screen frame. Referring to fig. 9, the screen is divided into 16 partitions by criss-cross of 4 vertical lines and horizontal lines, and 16 points are formed at the intersection angles of the partition lines and the screen frame, so that 16 light sensors are provided. 16 light sensors (S1-S16) are arranged around the frame of the screen to form a sensor array, and the whole screen is divided into 16 (A1-A4, B1-B4, C1-C4 and D1-D4) partitions. For example, the following steps are carried out: if strong outdoor light is irradiated onto the screen from the right side of the screen, a user sitting in front of the left side of the screen will be obviously subject to a light reflection problem caused by the reflected light of the screen. At this time, the 16 light sensors collect respective brightness data (see the data in attached table 1), and then transmit the data to the chip module for relevant operation processing. Attached table 1:
after the chip module receives the ambient brightness of 16 groups of positions, firstly calculating to obtain an average value Dav of the ambient brightness of the positions of 16 light sensors, namely 92.25, then comparing the difference between each brightness data and Dav, and finally positioning the partition of A4-D4 to have the maximum intensity influenced by outdoor illumination, wherein the reflection problem caused by the partition is most obvious, and the outdoor illumination intensity of the partitions of A3-D3 and A2-D2 is reduced in sequence. Based on the operation comparison result, the chip module sends a related instruction to the partitioned light control modules, and the partitioned light control modules respectively adjust different backlight brightness of the partitions A4-D4, A3-D3 and A2-D2 after receiving the instruction, so that the effect of eliminating the light reflection problem is achieved.
Further, based on the above embodiments, please refer to fig. 6, which shows an embodiment of the screen brightness adjusting method of the present invention, wherein step S52 includes:
s522, obtaining a partition with the largest difference and a partition with the smallest difference according to the difference between the ambient brightness of the position where each partition bordering on the screen frame is located and the average value;

and S526, adjusting the brightness of each partition to gradually weaken the brightness of the screen along the incident direction of the light.
In the process of adjusting the brightness of each partition according to the difference between the ambient brightness of the position of each partition bordering on the screen frame and the average value, the partition with the largest difference and the partition with the smallest difference are obtained, and then the light incidence direction is obtained by utilizing the connecting line direction between the partition with the largest difference and the partition with the smallest difference.
Further, based on the above-mentioned embodiment, please refer to fig. 7, which proposes an embodiment of the screen brightness adjusting method of the present invention, and step S526 includes:
s5262, dividing the screen into a plurality of equal light areas along the light incidence direction by taking a single partition as a unit;
s5264, adjusting the brightness of each subarea to enable the brightness of the equal light areas to gradually weaken from strong to weak along the light incidence direction, and the brightness of the subareas in the same equal light area is the same.
In this embodiment, the partition of the screen is divided into a plurality of equal light areas along the light incidence direction, and then the brightness of each partition is adjusted so that the brightness of the plurality of equal light areas gradually weakens from strong to weak along the light incidence direction, and the brightness of the partitions in the same equal light area is kept the same, which is beneficial to improving the adjustment efficiency. Because the brightness of a plurality of light areas along the incident direction of light rays is gradually weakened by the intensity under the irradiation of the light rays, when the brightness of the subareas is adjusted, the opposite operation is carried out, the brightness of each subarea is adjusted to ensure that the brightness of the light areas is gradually weakened by the intensity along the incident direction of the light rays, so that the problem of screen light reflection can be solved, and the adjustment by taking one light area as a unit is favorable for improving the adjustment efficiency.

Specifically, each partition comprises at least one unit light control area, wherein one screen is composed of a plurality of light control areas, and each light control area can be used for independently adjusting the brightness. And the brightness of each subarea is uniformly adjusted by adjusting the brightness of the unit light control area. Referring to fig. 8 and 9, fig. 8 is a schematic diagram of distribution of light control areas of a screen, as can be seen from fig. 8, the screen is composed of 64 light control areas and includes 8 rows and 8 columns of light control areas, fig. 9 is a schematic diagram of partitions of the screen, and the screen is totally divided into 16 partitions, that is, one partition includes 4 light control areas.
The acquisition module is used for acquiring the ambient brightness of the positions of the plurality of partitions, and the plurality of partitions at least comprise 4 partitions distributed in different directions of a screen;
because light can be at least from the screen of the incident screen of southeast northwest direction of screen, consequently a plurality of subregion have 4 at least and distribute at the subregion of screen equidirectional, then can ensure to obtain the ambient brightness of the position that equidirectional place is located to be favorable to judging the incident direction of light.
