Embodiment 1

[0022] figure 1 This is a schematic flow chart of a method for controlling a TV screen provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the TV screen when switching channels. The method can be executed by a TV screen control, and the device can It is implemented by software and / or hardware. Such as figure 1 As shown, the method includes:

[0023] S110. Obtain a channel switching request of the TV screen, where the channel switching request includes information of the target channel;

[0024] The channel switching request may be an infrared signal, and the channel switching request is usually sent by a user-controlled remote control transmitter through an infrared transmitting tube, and received by an infrared receiving head at the TV end.

[0025] Before obtaining the channel switching request of the TV screen, the TV terminal will receive the signals of all channels; when one of the TV channels is selected for playback...

Embodiment 2

[0037] figure 2 It is a schematic flow chart of a control method for a TV screen in the second embodiment of the present invention. On the basis of the first embodiment, this embodiment further explains the specific operation of display parameter switching, such as figure 2 As shown, the method includes:

[0038] S210: Obtain a channel switching request of the TV screen, where the channel switching request includes information of the target channel;

[0039] Further, the target channel information includes target channel frequency points, the screen display parameter set includes multiple sets of screen display parameters, and the screen display parameters include pixel clock signals.

[0040] The frequency of the target channel is used to mark the frequency of the signal of the target channel, and the frequency value of the signal marked by the frequency of different target channels is different.

[0041] The pixel clock signal is a very important clock signal, and the clock signal ...

Embodiment 3

[0058] image 3 Shown is a schematic structural diagram of a television screen control device provided in the third embodiment of the present invention, such as image 3 As shown, the control device for a TV screen includes: a switching request acquiring module 310, a target screen display parameter determining module 320, a display parameter switching module 330, and a channel switching module 340.

[0059] Wherein, the switching request obtaining module 310 is configured to obtain a channel switching request of the TV screen, and the channel switching request includes information of the target channel;

[0060] The target screen display parameter determination module 320 is configured to search for a preset screen display parameter set according to the information of the target channel, and determine the corresponding target screen display parameter;

[0061] The display parameter switching module 330 is configured to switch the current screen display parameters of the TV screen t...

Abstract

The invention discloses a control method and a control device for a television screen. The control method for the television screen comprises the steps of acquiring a channel switching request of the television screen, wherein the channel switching request comprises information of an objective channel; searching a screen display parameter set according to the information of the objective channel, and determining a corresponding objective screen display parameter; switching a current screen display parameter of the television screen to the objective screen display parameter according to the channel switching request; and switching the television screen to the objective channel. The control method and the control device settle a problem of noise points on a picture caused by tuner signal interference by the display parameter of the television screen. Through searching from the preset screen display parameter set and switching to the objective screen display parameter which matches the objective channel information, the television screen parameter can be automatically switched in a channel switching process, thereby preventing definition reduction of the television picture caused by noise points in the picture, improving program display quality and improving user experience.

Description

Technical field [0001] The embodiments of the present invention relate to the field of display devices, and in particular to a control method and device for a television screen. Background technique [0002] The advancement of multimedia technology has made modern people increasingly demanding high-quality images. The quality of the image is greatly related to the amount of noise that is accompanied by the image capture, signal conversion, and transmission process. [0003] In order to effectively remove noise and improve image quality, research on noise removal in the field of image processing has also received more and more attention. [0004] At present, our whole machine (TV) is prone to the problem of noise in the picture due to the mismatch between the display parameters of the TV screen and the tuner (tuner) signal. Summary of the invention [0005] The present invention provides a method and device for controlling a TV screen to solve the problem that the display parameters ...
