Abstract

The invention discloses a screen end control method and device of a module television. The screen end control method comprises following steps of A, initializing settings of the module television when the module television is turned on; B, detecting the state of an intelligent card; judging the permission of the intelligent card according to the state of the intelligent card; selecting to display the HDMI signals of a card end or the Test Pattern of the screen end; controlling the menu display of the screen end; storing related function parameters; and C, repeating the step B every other preset time until the module television is turned off. According to the method and the device, the HDM signals can be displayed better; and through entering into a factory pattern by the menu display of the screen end, leave factory debugging and after sale maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of modular televisions, in particular to a method and device for controlling screens of modular televisions. Background technique [0002] The modular TV divides the TV into the screen terminal belonging to the display part and the card terminal belonging to the intelligent function module. The card terminal and the screen terminal are connected through a specific connector for information interaction. The screen terminal can identify the smart card on the card terminal through the connector, then manage the power of the smart card and run different functional tasks according to the type of smart card, and display the corresponding video content on the screen terminal. The screen end of the modular TV and the card end cooperate with each other to realize functions such as TV, Internet access, and games. [0003] However, when the existing module TV is not inserted with a smart card, the screen terminal cann...
