Embodiment 1

[0066] refer to figure 1 , figure 1 The flow chart of the method for adjusting the LCD display viewing angle provided in this embodiment may specifically include:

[0067] Step 101: Obtain a picture including the position information of the user's pupil;

[0068]In this embodiment, before adjusting the viewing angle of the LCD display, a picture including the position information of the user's pupil is acquired first. Specifically, this embodiment may firstly identify the user's pupil, secondly, locate the user's pupil, and finally acquire a picture including the position information of the user's pupil.

[0069] In practical applications, a smart phone or a tablet computer equipped with an LCD has a front-facing camera. In this embodiment, the user's pupil can be identified by using the front-facing camera of the smart phone or tablet computer, and then positioned, and finally information including the position of the user's pupil is obtained. picture of.

Embodiment 2

[0087] In this embodiment, a smart phone using an LCD as a screen is taken as an example to introduce how to adjust the display viewing angle of the screen of the mobile phone. refer to image 3 , image 3 The flow chart of the method for adjusting the display angle of view of the mobile phone screen provided by this embodiment, wherein the smart phone has its own gravity sensor and front camera, and the method may specifically include:

[0088] Step 301: The front camera of the smart phone obtains a picture including the position information of the user's pupil;

[0089] In this embodiment, since the smart phone has a front camera, the front camera can be used to obtain a picture including the user's pupil position information, that is, to take a photo for the user who is currently using the smart phone, and save the photo in the smart phone Inside.

[0090] Step 302: The processor of the smart phone obtains the offset information of the user's pupil from the center of the...

Embodiment 3

[0098] refer to Figure 4 , Figure 4 The structural diagram of the device for adjusting the LCD display viewing angle provided in this embodiment, the device may include:

[0099] The first obtaining module 401 is used to obtain a picture including user pupil position information;

[0100] The second acquiring module 402 is configured to acquire the offset information of the user's pupil from the center of the LCD according to the picture;

[0101] The third obtaining module 403 is used to obtain the current inclination angle information of the LCD;

[0102] The adjusting module 404 is configured to adjust the display viewing angle of the LCD according to the current tilt angle information of the LCD and the offset information of the user's pupil from the center of the LCD.

[0103] Wherein, the device may also include:

[0104] An identification module, configured to identify the user's pupils;

[0105] A positioning module, configured to locate the pupil of the user. ...

Abstract

The embodiment of the invention discloses an LCD display angle adjusting method, device and system. The method comprises obtaining an image containing the pupil position information of a user, and then obtaining the pupil position offset information of the user according to the image; obtaining the current angle information of an LCD; adjusting the display angle of the LCD according to the current angle information of the LCD and the pupil position offset information of the user. The LCD display angle adjusting method, device and system can achieve automatic LCD display angle adjustment according to use pupil position information and data which are obtained or identified by a gravity sensor of an LCD smartphone or an LCD tablet computer, thereby enabling the user to experience the best visual perception; due to the fact that the LCD display angle can be adjusted automatically according to the pupil position change of the user, for the user, the current LCD is a wide-angle LCD, and for people around the user, the current LCD is a narrow-angle LCD, so that the people around the user cannot see the content on the display clearly due to the narrow angle, further user privacy can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device and system for adjusting an LCD display viewing angle. Background technique [0002] LCD (Liquid Crystal Display) liquid crystal displays are widely used in people's daily life. Today's smartphones and tablet computers mostly use LCDs with wide viewing angles as display devices. Among them, the viewing angle of the wide viewing angle LCD is fixed. If the user uses a mobile phone or a tablet computer in a public place, people around can see the LCD screen of the mobile phone or tablet computer that the user is using, which makes the privacy of the user's open screen leaked. Danger. [0003] In order to solve the problem of leaking user privacy, narrow viewing angle LCDs are directly used as display devices for smart phones and tablet computers in the prior art. The content on the screen can only be seen clearly within a narrow viewing angle, which makes ...
