[0003] Because the picture frame TV has a better display effect when playing pictures, it is loved by users. However, when playing pictures, the picture frame TVs in the prior art still need to switch the playing state manually, such as: waiting to play Some pictures in the pictures are suitable for playing in landscape display mode, and some pictures are suitable for playing in portrait mode. When the user is close to the TV, it is convenient to use the landscape display mode to play pictures or videos. When the user is far away When playing in portrait display mode, better results can be obtained. However, the existing picture frame TVs cannot automatically switch between horizontal and vertical display modes according to the format of the picture to be played or the distance between the user and the TV. When the user needs to change the display mode, it needs to be executed manually, which brings inconvenience to the user, and the intelligence of the picture frame TV cannot meet the needs of the user

Embodiment Construction
[0044] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0045] A microphone array for receiving sound signals is generally installed on the frame of a picture frame TV in the prior art. In order to obtain a better sound collection effect, the general microphone array is set above the TV frame and lined up in the horizontal direction. The microphones in the microphone array are set at equal intervals. When the TV is in the horizontal screen display mode, it can receive short-range voice functions Stronger, and the function of receiving far-field voice is relatively poor, so in the present invention, in order to achieve a better voice signal li...

The invention provides a method for switching between horizontal and vertical screens of a picture frame TV and a picture frame TV. Two sets of microphone arrays arranged relatively vertically are installed on the frame of the picture frame TV, and two sets of microphone arrays are used to collect sound signals. Analyze the sound signal to determine whether the sound signal is a screen switching instruction, if the collected sound signal is a screen switching instruction, then switch the current screen to the display mode corresponding to the screen switching instruction. The method of the present invention can ensure that the normal voice collection function can be realized when the TV is in the horizontal screen or vertical screen mode by setting the vertically distributed horizontal voice collection unit and the vertical voice collection unit, and realizes it based on the analysis of the sound signal The horizontal and vertical screen control of the TV is performed through the received sound signal, which improves the intelligence of the TV and brings convenience to the user at the same time.
Description
technical field [0001] The invention relates to the technical field of televisions, in particular to a method for switching between horizontal and vertical screens of a picture-frame TV and the picture-frame TV. Background technique [0002] Picture frame TV integrates the functions of ordinary TV and electronic photo frame. The user stores pictures in the electronic photo frame, triggers the switch of the electronic photo frame, and the stored pictures can be displayed through the electronic photo frame, which is very simple. [0003] Because the picture frame TV has a better display effect when playing pictures, it is loved by users. However, when playing pictures, the picture frame TVs in the prior art still need to switch the playing state manually, such as: waiting to play Some pictures in the pictures are suitable for playing in landscape display mode, and some pictures are suitable for playing in portrait mode. When the user is close to the TV, it is convenient to us...
