Embodiment Construction

[0017] Various embodiments of the present invention are described with reference to the above-mentioned drawings.

[0018] The method for changing the display area of ​​the TV screen comprises the following steps:

[0019] a) Input the coordinates of the set start point and the set end point displayed on the screen for receiving specific information into the TV image controller;

[0020] b) When the scanning signal output by the TV to the screen for each frame of image does not reach the set starting point coordinates, the image controller controls the video signal output unit to output the set fixed signal, and the information sent by the TV itself is displayed on the screen;

[0021] c) When the scanning signal of each frame of image output to the screen reaches the set starting point coordinates, the image controller controls the video signal output unit to output the received specific information, and the screen displays the received specific information;

[0022] d) When...

Abstract

A method for changing the display area of ​​a TV screen includes the following steps: inputting the set start point and set end point coordinates when receiving specific information displayed on the screen to the TV image controller; when the scanning signal does not reach the set start point coordinates, the screen The information sent by the TV itself is displayed on the screen; when the scanning signal reaches the set start point coordinates, the screen displays the received external video information; when the scan signal exceeds the set end point coordinates, the screen displays the information sent by the TV itself again, the specified The information is external video information, especially computer information. The present invention can be used on the existing large-size flat-panel TV without changing the hardware and structure. When displaying video information or computer (PC) information that needs to be narrowed down on a large-screen flat-panel TV, it provides a reduced-screen The viewing method makes it more suitable for the user's usage habits. When the native resolution of the TV is higher, the effect of the reduced display area is better.

Description

technical field [0001] The present invention relates to an image display device, in particular to a television set that can be used as a display screen for a computer. Background technique [0002] At present, large-size TVs, especially large-size and high-resolution flat-panel TVs, are very common. The mainstream size of living room TVs has reached more than 42 inches, and most of the TVs used in bedrooms are 26 or 32-inch flat-screen TVs. . Most of these large-size flat-panel TVs have VGA or DVI interfaces, which can be used as computer monitors. When large-screen TVs were used as PC monitors in the prior art, the display method was traditional full-screen display. Its implementation method is as image 3 As shown in the figure, the screen display and the SCALER output waveform should be one-to-one corresponding waveforms, that is, the waveform in the figure is the output of the scaling engine (SCALER) and the screen display waveform, the top is the clock waveform, and th...
