An embodiment of the present invention provides a method for adjusting a screen curvature, and referring to fig. 2, fig. 2 is a flowchart of a first embodiment of the method for adjusting a screen curvature according to the present invention.
In this embodiment, the screen curvature adjustment method includes the steps of:
step S101, distance information between at least one user in front of the display screen and the display screen is acquired.
The user may be a natural person who stays on the display screen and views the display content on the display screen. And the user may be one or a plurality of users. And the distances of the multiple users from the display screen may or may not be consistent. Corresponding distance data exist between each user and the display screen, and the collection of the distance data and other data between all the users and the display screen forms the distance information of the step. It should be noted that, in this step, in order to make the curvature adjustment of the display screen better, the user may be a natural person whose distance from the display screen is smaller than the preset distance, so as to exclude a natural person farther from the display screen, and avoid affecting the curvature adjustment result. And in some embodiments, to avoid that natural persons who cannot actually view the display screen affect the curvature adjustment result, natural persons located outside the viewing angle of the display screen may also be excluded from the user.
Step S102, obtaining the target curvature of the display screen according to the distance information.
In this embodiment, the curved display may calculate, according to the distance information, a suitable curvature of the display screen, and when the screen curvature of the curved display screen is adjusted to the suitable curvature, the display screen may enable the user to have a wider viewing angle, more conform to the structure of the human eye, and have a better stereoscopic impression, and may generate a certain naked eye 3D visual effect. The suitable curvature is the target curvature of the display screen.
Step S103, adjusting curvature parameters of the display screen according to the target curvature.
After the target curvature is calculated, the curved surface display controls the display screen to adjust the curvature parameters, so that the curved surface display automatically adjusts the curvature parameters of the display screen under the condition that the user does not send corresponding adjusting instructions or even feel is not caused, and all users can obtain relatively good viewing experience.
In one embodiment, referring to fig. 3, the distance information includes a maximum value of an angle θ formed between a line between at least one user and a center axis of the display screen and a vertical center line of the display screen. When the curved display is placed vertically, the vertical center line of the display screen is a straight line a which is vertical to the central axis of the display screen in the horizontal plane. When the user views the display screen in front of the display screen, at any moment, the user and the display screen are relatively static, so that an included angle theta is formed between a connecting line between the user and the central axis of the display screen and the vertical central line of the display screen, and the included angle theta can be 0 degree, namely, the user is positioned right in front of the display screen. The maximum of the plurality of angles θ can then be obtained.
At this time, step S102 is: and obtaining the target curvature of the display screen according to the maximum value of the included angle.
The curvature of the display screen is adjusted according to the user with the largest included angle with the central axis of the display screen, namely, the user with the worst viewing angle, so that the user with the worst viewing angle can obtain better viewing experience, partial pictures of the display screen can not be seen by the user, and all users in front of the display screen can obtain better experience.
For example, after obtaining the maximum included angle formed by the vertical midline between the user and the television screen, the maximum included angle can be used as the curvature of the maximum curved surface which can be formed by the corresponding screen in the current state, namely the target curvature.
Further, on the basis of the first embodiment of the method of the present invention, a second embodiment of the method of the present invention is presented. Referring to fig. 4, fig. 4 is a schematic flow chart of a second embodiment of the method of the present invention.
In this embodiment, the distance information includes an average value of horizontal distances of at least one user from a center axis of the display screen. Referring to fig. 3, any user is horizontally spaced from the center axis of the display screen by a distance b. The value of b can be obtained by calculating according to the included angle theta and the distance c between the user and the vertical center line a of the display screen. When there is only one user, the horizontal distance between the user and the central axis of the display screen is the average value.
In this embodiment, after step S103, the method further includes:
step S104, obtaining a correction value of the curvature parameter according to the average value of the horizontal distance.
Step S105, correcting the curvature parameter of the display screen according to the correction value.
In this embodiment, the correction value of the curvature parameter may be obtained according to the average value of the horizontal distance, so that the curvature of the display screen is fine-tuned according to the correction value, so that all users obtain relatively good viewing experience.
As an option of this embodiment, the correction value is positively correlated with the average value. If the average distance is larger, the curvature of the television can be properly amplified, so that all users can see all pictures of the display screen, the structure of human eyes can be more met, and a certain naked eye 3D visual effect can be generated through better stereoscopic impression.
Further, on the basis of the first and second embodiments of the method of the present invention, a third embodiment of the method of the present invention is presented. Referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of the method of the present invention.
