Display, device and method for accomplishing sight protection

Abstract

The invention provides a display, a device and a method for realizing sight protection for increasing the sight protection function of the display and other devices. The display provided by the invention comprises: a display unit for displaying data; an image collecting unit for collecting the face image of a current user; a sight protection unit for sending an alarming message to the user when a distance between the eyes of the user and the display unit is smaller than a threshold value which is set in advance; wherein, distance between the eyes of the user and the image collecting unit is equal to the distance between the eyes of the user and the display unit, the image collecting unit and the display unit are right opposite to the eyes of the user.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a display, a device and a method for realizing vision protection. Background technique [0002] 80% of people's information comes from eyes. With the popularity of computers and TVs, more and more people need to watch the monitor for a long time. If the distance from the monitor is too close, it will cause damage to vision. Therefore, more and more People are near-sighted due to watching the monitor at close range for a long time. [0003] There are some devices for protecting eyesight in the prior art, including the methods of measuring the distance of objects in a mechanical way and using sensors such as infrared rays to measure the distance between objects. [0004] The method of measuring the distance of objects mechanically requires people to wear some headgear-like devices, and the distance between people and books or displays is limited by the distance of the rod. The...

Problems solved by technology

[0004] The method of measuring the distance of objects mechanically requires people to wear some headgear-like devices, and the distance between people and books or displays is limited by the distance of the rod. These devices will make people feel uncomfortable and affect people's emotions when studying and working. Intrusive and, moreover, limited distance measurement range

[0005] When the sensor is used to measure the distance between objects, the transmitting device is generally used to actively emit infrared rays or ultrasonic waves, etc., and the receiving device is used to receive the infrared rays or ultrasonic waves reflected back from the object, and by measuring the distance between the emitted infrared rays or ultrasonic waves and the receiving infrared rays or ultrasonic waves Time interval or phase difference is used to measure the distance between objects. However, using sensors to measure the distance between objects will cause great interference, whether it is a person in front of the sensor, or a book, chair, small animal, etc. When various objects are in front of the sensor, the sensor will consider it as a person and measure the distance. When the distance is less than the allowable value, a reminder will be issued, resulting in an error message
