a modular tv

Abstract

The invention relates to a modularization television, comprising a television mainboard and a backlight drive module, a power module, screen external peripherals and a display screen that are electrically connected with the television mainboard. The television mainboard is divided into a functional application module and a screen end drive module that are in communicated connection. The functional application module receives and processes audio and video signals of the television. The screen end drive module receives an audio signal and a video signal that are processed by the functional application module and respectively outputs the processed audio signal and the video signal to the screen external peripherals to output audio and to the display screen to display the video. The screen end part with small operation amount is separated from an original television mainboard. As for the functional application part, the television main CPU and IC can be designed separately or upgraded according to user demand. Generally, the screen end is not replaced during the service life of the television. The display drive circuit is not redeveloped and redesigned. Major function upgrading can be realized only by upgrading the functional application module. The modularization television facilitates upgrading of the television, and lowers the upgrading cost.

Description

technical field [0001] The invention relates to a television, in particular to a modular television. Background technique [0002] With the development of large-scale integrated circuits, televisions have also developed from the structure of single-chip microcomputers plus discrete devices to the structure of large-scale integrated ICs, and the degree of integration is getting higher and higher. With the introduction of 2-core, 4-core, 8-core CPU integrated with multiple GPU TV processing chips, the processing IC function of the TV is getting stronger and stronger. At present, it is basically a processing IC that can manage the corresponding applications and peripheral equipment of the TV. drive. The circuit structure built by the TV processing IC is located on the main board of the TV, and is responsible for driving, scheduling, and managing all peripheral devices around the TV. However, as far as TV peripherals are concerned, different peripherals have different needs fo...

AI Technical Summary

Problems solved by technology

Upgrading the TV with this structure requires replacing the main board of the TV. If the main board of the TV is not replaced, the newly added peripherals cannot be adapted, so that the function of the TV will soon fail to meet the needs of users during its relatively long life cycle.

For research and development work, upgrading means that the research and development related to display and drive needs to be upgraded according to the TV application and TV processing IC. needs to be redone, thus creating a lot of unnecessary waste

Moreover, for users, it is very inconvenient to upgrade the TV motherboard because of some external devices, and it is impossible to carry out customized development and upgrade
