Embodiment Construction

[0020] see image 3 According to one embodiment of the present invention, the TV set includes a signal demodulation module, a video decoding module, a video image scaling module, a video display module, a display mode control module and a preset image providing module. The signal demodulation module, the video decoding module, the video image scaling module and the video display module are connected in sequence. The signal demodulation module is used for demodulating the television signal received by the television. The video decoding module is used for decoding the demodulated TV program video signal. The video image scaling module is used to scale the decoded video signal so that the size of the processed video signal matches the size of the TV screen. The video image scaling module has two working modes: image full screen mode and image filling mode . The video display module is used to display the scaled video image, which can be one of LCD display, PDP display, CRT dis...

Abstract

The invention provides a television, which comprises a signal demodulation module, a video decoding module, a video image scaling module, a display mode control module, a preset image providing module and a video display module, the signal demodulation module is used for receiving and demodulating television signals, the video decoding module is used for decoding television program video signals received by the television, the video image scaling module is used for scaling decoded video signals, so that the size of the processed video signal is matched with the size of the display area of the television screen, the video image scaling module includes two operating modes, i.e. an image full screen mode and an image filling mode, the display mode control module is used for selecting the operating mode of the video image scaling module, the preset image providing module is used for providing a preset filling image for the video image scaling module under the image filling mode, and the video display module is used for displaying scaled video images. The television can provide good visual experience for users and prevent the occurrence of the image persistence phenomenon. The invention also provides an image display method of the television.

Description

technical field [0001] The invention relates to a television set, and also relates to an image display method of the television set. Background technique [0002] The aspect ratio of the video image of the traditional TV signal is generally 4:3. With the development of TV technology, digital TV standards in many countries stipulate that the aspect ratio of high-definition digital TV is 16:9. Therefore, many TV manufacturers have begun to change their main products from TVs with an aspect ratio of 4:3 to TVs with an aspect ratio of 16:9 to conform to the trend of the times. However, the replacement of TV sets is a lengthy process. Therefore, for a long period of time, there will be a TV with an aspect ratio of 4:3 and a TV set with an aspect ratio of 16:9. The coexistence of TV signals with a ratio of 4:3 and TV signals with an aspect ratio of 16:9 often leads to the situation that the aspect ratio of the TV screen is inconsistent with the aspect ratio of the TV signal. ...
