Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] In the embodiment of the present invention, the remote controller matched with the TV is different from the existing remote controller of the TV. The remote controller provided by the embodiment of the present invention is provided with an ultrasonic generator on the existing remote controller. The existing infrared emitters are connected, and when the infrared emitter emits a remote control signal, the ultrasonic generator is triggered at the same time, and the ultrasonic generator simultaneously emits ultrasonic waves with a frequency of 38kHz.

Abstract

The invention is applicable to the technical field of televisions and provides a television with the viewing distance warning function and a realizing method thereof, and the method comprises the following steps: a) calculating the transmission time of an ultrasonic signal sent by a remote controller of the television; and b) calculating the current viewing distance according to the transmission time of the ultrasonic signal and the transmission speed, comparing the current viewing distance with the preset normal viewing distance, and calling warning information for display if the current viewing distance exceeds the range of the normal viewing distance. The technical scheme can carry out real-time monitoring on the current viewing distance of a user, emit the warning information when the viewing distance exceeds the preset range and further remind the user of protecting eyesight.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to a television with a viewing distance warning function and a realization method thereof. Background technique [0002] As TV program information becomes more and more abundant, existing TV sets have become one of the main tools for people’s recreation and entertainment, and users spend more and more time watching TV programs every day, and the impact of watching TV for a long time on eyesight has also become a Many users are concerned about the problem. [0003] The factor that has the greatest impact on the user's vision is that the TV viewing distance (referred to as the viewing distance in the present invention) is too short, especially for minors, the viewing distance is too short, which will greatly damage their vision. [0004] Therefore, a technical solution is needed, which can monitor the viewing distance in real time when the user is watching a TV progra...
