Embodiment 1

[0022] figure 1 It is a schematic flow chart of a TV screen control method 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 controlling a TV screen. The device can Realized by means of software and / or hardware. Such as figure 1 As shown, the method includes:

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

[0024] The channel switching request can be an infrared signal, and the channel switching request is usually sent by the remote control transmitter controlled by the user through the infrared emitting tube, and received by the 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 to pl...

Embodiment 2

[0037] figure 2 It is a schematic flowchart of a control method for a TV screen in Embodiment 2 of the present invention. On the basis of Embodiment 1, this embodiment further elaborates on the specific operation of display parameter switching, as shown in figure 2 As shown, the method includes:

[0038] S210. Obtain a channel switching request on the TV screen, where the channel switching request includes information about the target channel;

[0039] Further, the information of the target channel includes the frequency point of the target channel, the set of screen display parameters includes multiple sets of screen display parameters, and the screen display parameters include a pixel clock signal.

[0040] The frequency point 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 point of different target channels is different.

[0041] The pixel clock signal is a very import...

Embodiment 3

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

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

[0060] The target screen display parameter determination module 320 is used 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 scree...

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 improvement of multimedia technology has made modern people's requirements for high-quality images increasingly higher. The image quality is closely related to the amount of noise generated during image capture, signal conversion, and transmission. [0003] In order to effectively remove noise and improve image quality, more and more attention has been paid to the research on noise removal in the field of image processing. [0004] At present, our whole 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. Contents of the invention [0005] The invention provides a TV screen control method and device to solve the problem that the display parameters of the TV screen inte...
