Abstract

A system for adjusting a view angle of a display can automatically adjust a view angle of the display to prevent lights from reflecting on the display. A plurality of sensors detect light intensities of a plurality of directions around the display, and send the detected light intensities to an adjusting device. The adjustment device calculates the light intensities to get a sum and an average of the light intensities, and controls the view angle of the display to be turned a corresponding degree in response to light intensities of some directions being greater than the average and a preset value.

Claims

1. A system for adjusting a view angle of a display, the system comprising:

a plurality of sensors mounted on the display, to detect light intensities of a plurality of directions around the display at an interval, and output the light intensities; and

an adjustment device connected to the plurality of sensors and the display, the adjustment device comprising a processor and a memory connected to the processor, the memory comprising a plurality of modules each of which stores one or more computerized instructions to be executed by the processor, wherein the plurality of modules comprises;

a calculation module to receive the light intensities and calculate the light intensities to get a sum and an average of the light intensities;

a comparison module to determine whether the light intensity of each of the plurality of directions is greater than the average and a preset value, and calculate how many degrees of view angle towards the direction of the display need to be turned according to a difference between the average of the light intensities and the light intensity of the direction in response to the light intensity of the direction being greater than the average and the preset value; and

a control module to control the view angle of the display to be turned a corresponding degree according to the determination of the comparison module.

2. The system of claim 1, wherein each sensor is arranged on a middle of each edge of the display.

3. The system of claim 1, wherein each sensor is arranged on each corner of the display.

4. The system of claim 1, wherein if a first degree of the view angle towards a first direction needing to be turned is greater than a second degree of the view angle towards a second direction opposite to the first direction of the display needing to be turned, the control module controls the view angle towards the first direction of the display to be turned a degree difference between the first and the second directions, in response to light intensities of the first direction and the second direction being greater than the average and the preset value and the light intensity of the first direction is greater than that of the second direction, and vice versa;

wherein the view angles of the display remain unchanged in response to the first degree of the view angle towards the first direction needing to be turned being equal to the second degree of the view angle towards the second direction of the display needing to be turned.

5. A method for adjusting a view angle of a display, the method comprising:

detecting light intensities of a plurality of directions around the display, and outputting the light intensities, by a plurality of sensors mounted on the display;

calculating the light intensities to get a sum and an average of the light intensities; and

determining whether the light intensity of each of the plurality of directions is greater than the average and a preset value, calculating how many degrees of view angle towards the direction of the display need to be turned according to a difference between the average and the light intensity of the direction in response to the light intensity of the direction being greater than the average and the preset value, and controlling the view angle of the display to be turned a corresponding degree.

6. The method of claim 5, wherein each sensor is arranged on a middle of each edge of the display.

7. The method of claim 5, wherein each sensor is arranged on each corner of the display.

8. The method of claim 5, wherein if a first degree of the view angle towards a first direction needing to be turned is greater than a second degree of the view angle towards a second direction opposite to the first direction of the display needing to be turned, the control module controls the view angle towards the first direction of the display to be turned a degree difference between the first and the second directions, in response to light intensities of the first direction and the second direction being greater than the average and the preset value and the light intensity of the first direction is greater than that of the second direction, and vice versa;

wherein the view angles of the display remain unchanged in response to the first degree of the view angle towards the first direction needing to be turned being equal to the second degree of the view angle towards the second direction of the display needing to be turned.
