Problems solved by technology

Since the source type and signal transmission mode of the input channel are preset at the factory, they must be matched with the management program displayed on the machine and realize the function of the standard interface. As a result, the user cannot adjust and realize multiple channels on the LCD TV by himself. monitors synchronously with each VGA source, thus wasting resources

Embodiment Construction

[0011] The specific embodiment of the present invention includes sending interrupt request to the management pig program and adding VGA and SCART interfaces to the picture-in-picture management subroutine, especially the management program to the SCART interface. In the state where the interrupt program is valid, it is mainly the establishment of the information interaction relationship between the display screen area and the signal source. Drawing the main display area of ​​planting flowers under the corresponding relationship established at random may not meet the wishes of the supporters, so it is necessary to set the continuous start "multi-source synchronous monitoring status" key to forcibly change the display area. It is also possible to realize the random code sequence rotation of each interface by pressing the "multi-source synchronous monitoring state" key multiple times, and realize the rotation of each computer screen display area.

[0012] In this method, setting ...

Abstract

The present invention relates to a method of realizing synchronous monitoring on a plurality of VGA sources of a LCD TV; and resolves the technical problem that the LCD TV designed and produced by the method can be simply operated and set to realize the synchronous block-division display and in-phase monitoring of the VGA signal source outputted by a plurality of computers via a TV set. The technical proposal is realized when the TV set has basic configurations including a liquid crystal display, a VGA port and at least two SCART ports with the support of a TV-set central control unit and a management program. The present invention has the advantages that the TV set, which is designed and produced by using the method, can greatly extend the product functionality and effectively save resources without increasing the production cost.

Description

technical field [0001] The invention relates to a method for adjusting, selecting and switching input source channels of TV sets, especially for liquid crystal TVs with existing standard interface configurations. Specifically, it is a method for realizing synchronous monitoring of multiple VGA sources on a standard-configured LCD TV. Background technique [0002] Existing digital TVs or LCD TVs, the input interface is usually equipped with a traditional configuration of 1-way computer VGA input, 1-2-way HDMI input, and 1-2-way SCART input ports, which basically meet customer needs. However, there are some specific users who have multiple computers at home, and it is very troublesome to take care of and operate multiple monitors at the same time during work. Using the existing multiple input ports, the images displayed or received by multiple computers can be output to one LCD screen at the same time. It can greatly facilitate these special users, and also expands the funct...
