1. Technical Field
The present disclosure relates to a system and a method for adjusting a view angle of a display.
2. Description of Related Art
Currently, various display devices, such as television displays, computer displays, etc., mostly provide flat surfaces. When a user is viewing images on a flat display device, surrounding lights may reflect on the display device and cause uncomfort to the user's eyes. Moreover, most display devices only focus on appearance of having an appealing visual effect but lack view angle adjustment. Therefore, the user may need to manually adjust the view angle of the display device to reduce the reflective lights, thereby causing inconvenience for the user.
Referring to
The adjustment device 30 includes a processor 302 and a memory 306. The processor 302 is connected to the memory 306. The memory 306 includes a calculation module 308, a comparison module 310, and a control module 312, each of which stores one or more computerized instructions to be executed by the processor 302.
The plurality of sensors 20 detect light intensities of a plurality of directions (e.g., a top right direction, a top left direction, a bottom left direction, and a bottom right direction of the display 10 or a middle of each edge of the display 10) around the display 10 at an interval, such as every 30 minutes, and send the detected light intensities to the calculation module 308.
The calculation module 308 calculates the light intensities to get a sum and an average of the light intensities.
The comparison module 310 determines whether the light intensities of the plurality of directions are greater than the average of the light intensities and a preset value, for example, stored in the memory 306. If the light intensities of some directions are greater than the average and the preset value, the comparison module 310 calculates how many degrees (e.g., 7 degrees) of view angles of the display 10 need to be turned towards the directions. In this embodiment, a method to calculate how many degrees of view angles of the display 10 need to be turned towards the directions is as follows. For example, if the light intensity of one direction is greater than the average (e.g., n) and the preset value, the display 10 needs to turn towards the direction 2n degrees. If the light intensities of two opposite directions, such as left and right of the display 10 are greater than the average and the preset value, for example, the light intensity of the left of the display 10 is three degrees greater than the average, indicating that the left of the display 10 needs to turn six degrees, the light intensity of the right of the display 10 is five degrees greater than the average, indicating that the right of the display 10 needs to turn ten degrees. A degree difference of turned view angles between the left and the right of the display 10 is 4 degrees, which means the display 10 needs to turn 4 degrees towards right. The maximum degrees of view angles which the display 10 can turn are preset at a certain value, e.g., 25 degrees, from an initial degree of a view angle of the display 10.
The control module 312 controls the display 10 to turn a corresponding view angle.
In step S100, the plurality of sensors 20 detect light intensities of a plurality of directions (e.g., a top right direction, a top left direction, a bottom left direction, and a bottom right direction of the display 10 or a middle of each edge of the display 10) around the display 10, and send the detected light intensities to the calculation module 308.
In step S102, the calculation module 308 calculates the light intensities to get a sum and an average of the light intensities.
In step S104, the comparison module 310 determines whether the light intensities of the plurality of directions are greater than the average and a preset value. If the light intensities of some directions are greater than the average and the preset value, the procedure goes to step S106. If the light intensities of all directions are not greater than the average and the preset value, the procedure goes to step S108.
In step S106, the comparison module 310 calculates how many degrees of the view angles of the display 10 need to be turned towards the directions. The control module 312 controls the display 10 to turn a corresponding degree. If light intensities of a first direction and a second direction opposite to the first direction of the display 10 are greater than the average and the preset value, and a first degree of the view angle towards the first direction needing to be turned is greater than a second degree of the view angle towards the second direction of the display 10 needing to be turned, the display 10 needs to turn a degree difference towards the first direction. If the first degree of the view angle towards the first direction of the display 10 needing to turn is equal to the second degree of the view angle towards the second direction of the display 10 needing to be turned, the display 10 remain unturned.
In step S108, the procedure returns to step S100 after a period of time, such as 30 minutes.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
