Abstract

The invention relates to a television terminal with an improved power supply and a signal connection structure. The television terminal comprises a power board, an auxiliary control circuit board, a main control circuit board, a driving circuit board and a sequential control circuit board, wherein the auxiliary control circuit board is electrically connected with the power board, the main control circuit board, the driving circuit board and the sequential control circuit board, the power board provides a power signal to the driving circuit board through the auxiliary control circuit board, the main control circuit board provides an image signal to the sequential control circuit board through the auxiliary control circuit board, and the auxiliary control circuit board is used for providing a backlight control signal to the driving circuit board. The television terminal is simpler and more reasonable in internal wiring, and the thickness of the television terminal can be further decreased.

Description

technical field [0001] The invention relates to a television terminal, in particular to a television terminal with an improved power supply and signal connection structure. Background technique [0002] In today's daily life, television has become an indispensable product. With the improvement of people's audio-visual effects and aesthetic requirements for appearance, TVs are required to have characteristics such as large size, thinness, and high image quality. [0003] The overall thickness of the LCD TV mainly depends on the LCD module, so thinning the thickness of the TV mainly starts with thinning the thickness of the LCD module, including the backlight, liquid crystal layer, optical film and circuit board. As for the improvement of image quality, it is mainly optimized from two aspects: image and backlight. In terms of image, various algorithms are mainly used to optimize the picture effect, such as improving the picture contrast, increasing the image layering, and ad...
