CROSS REFERENCE OF RELATED APPLICATIONS

The present application claims priority to the Chinese Patent Application No. CN201811579696.2, filed with the National Intellectual Property Administration, PRC on Dec. 24, 2018 and entitled “METHOD FOR DISPLAY CONTROL AND DISPLAY DEVICE”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates to the field of display technologies, and particularly to a method for display control and a display device.

BACKGROUND

The statements herein merely provide background information related to the present application and do not necessarily constitute the conventional art.

Display panels have many advantages such as thin body, power saving, and absence of radiation, and are widely used. The rationale of display panels is to provide liquid crystal molecules in two parallel glass substrates and apply a driving voltage on the two glass substrates to control the orientation of the liquid crystal molecules, so as to refract the light of backlight modules to generate an image. With the development of display panels, displayed images are brighter and clearer, and a long term of watching may cause visual fatigue.

Currently, children usually spend more time on watching TV. However, lack of self-control and abstinence always poses a long term of watching, which greatly compromises the vision, resulting in an increasing proportion of myopia in children. In addition to the artificial restriction of parents, some televisions may also provide timed turn-off functions. Such functions always lacks flexibility, and the television will also be turned off when an adult is watching. Children will suffer from reduced vision due to long-term watching, while adults may be bothered by tuned turn-off functions.

SUMMARY

The present application provides a method for display control and a display device, which can intelligently protect the vision of children without compromising the watching experience of adults.

For the above purpose, the present application provides a method for display control, including:

detecting program information: acquiring information of a currently displayed program;

determining a children's program: identifying the children's program based on the program information; and

controlling the displaying: if the program is not a children's program, displaying the program normally on a television, and if the program is a children's program, starting a preset protection mechanism.

The present application further discloses a method for display control, including:

detecting program information: acquiring information of a currently displayed program;

determining a channel: identifying whether the channel is a children's channel based on channel information, if not, displaying the program normally on a television, and if yes, determining a color saturation;

determining the color saturation: determining whether the color saturation is greater than 80, if not, displaying the program normally on the television, and if yes, determining a displaying time;

determining the displaying time: determining whether the displaying time is greater than the preset time, if not, displaying the program normally on the television, and if yes, starting a protection mechanism; and

starting the protection mechanism: popping up a prompt message and a password input box, if a password is input, displaying the program normally on the television, and if not, turning off the television.

The present application further discloses a display device, including: a television;

a detection component configured to acquire information of a currently displayed program;

a determining component configured to determine whether the program is a children's program; and

a control component configured to control whether to turn off a television, if the program is not a children's program, displaying the program normally on the television, and if the program is a children's program, starting a protection mechanism.

Compared with the scheme of adding a child lock to the television, the present application acquires the program information of the currently displayed content, and determines whether the currently displayed content is a children's program according to the program information. Whether the program is a children's program is intelligently identified. If the program is a children's program, a corresponding protection mechanism is started to effectively limit children from watching the television and to protect their vision. On the contrast, the watching experience of adults is not influenced.
