Played background adjusting and control device for smart TV

Abstract

The invention relates to a played background adjusting and control device for a smart TV. The adjusting and control device comprises a bearing base, a clamping groove, a working head, a ranging device, an environment light sensor, a timing circuit, a control circuit, a wireless data communication device, a series communication device and a communication terminal. At least one clamping groove is formed in the lower end face of the bearing base. The upper surface of the bearing base is connected with the working head in a slide mode through a slide rail. The working head is of a sealed cavity structure and internally evenly provided with a plurality of partition plates. The working head is divided into a detection cavity and a working cavity through a partition plate. The timing circuit, thecontrol circuit, the wireless data communication device and the series communication device are embedded in the working cavity. On one hand, the adjusting and control device can be effectively used in cooperation with various current smart TVs, and the device universality is greatly improved; on the other hand, and the screen display brightness of the smart TV can be automatically adjusted according to the environment illumination conditions during running of the smart TV and the distance between a watcher and a smart point.

Description

technical field [0001] The invention relates to an auxiliary device for a smart TV, in particular to a playback background control device for a smart TV. Background technique [0002] With the promotion and popularization of smart TVs, various types of smart TVs are used in a huge amount, but in the process of using smart TVs, it is found that the brightness of the display screen of the current smart TVs is often in a constant state during operation, so on the one hand, it leads to This shows that the energy consumption of the current smart TV is relatively high during operation. On the other hand, it also causes that the brightness of the TV screen cannot be effectively adjusted when the background lighting conditions of different environments and the distance between the viewer and the TV change. As a result, the brightness of the TV screen is likely to cause visual fatigue of the viewer, and even cause visual impairment in severe cases. To solve this problem, the current ...

[0002] With the promotion and popularization of smart TVs, various types of smart TVs are used in a huge amount. However, in the process of using smart TVs, it is found that the brightness of the display screen of the current smart TVs is often in a constant state during operation. This shows that the energy consumption of the current smart TV is relatively high during the operation process. On the other hand, it also causes the brightness of the TV screen to be unable to be effectively adjusted when the background lighting conditions of different environments and the distance between the viewer and the TV change. As a result, the brightness of the TV screen is likely to cause visual fatigue to the viewer, and even cause visual impairment in severe cases. To solve this problem, the current main method is to integrate the ambient light sensor in the smart TV or set a stepped screen brightness control circuit for the TV. To meet the needs of the screen brightness adjustment operation when the smart TV is running, but this method, on the one hand, has the disadvantages of increasing the cost of the smart TV and poor flexibility of the brightness control operation, and on the other hand, it also leads to the integrated in the smart point room. The detection range and sensitivity of the ambient light sensor are poor, and at the same time, it is impossible to detect the distance between the viewer and the smart TV and adjust the brightness of the TV screen. Therefore, in response to this problem, it is urgent to develop a new background brightness adjustment device for smart TVs , to meet the needs of practical use
