TCON drive circuit applied to notebook computer

Abstract

According to a TCON drive circuit applied to a notebook computer, a power supply module, a main control module, a storage module, a brightness adjusting module and an output module are arranged. In the actual application process, due to the fact that the output module comprises the multiple output units, the output units can input processed LVDS signals to the display screen, the display screen can receive more image information, the imaging definition of the display screen is improved, and the resolution of the display screen is guaranteed; besides, the main control module comprises an anti-surge unit, and the anti-surge unit can absorb surge current, so that the circuit is effectively prevented from being damaged by overlarge surge current, and the circuit cannot work normally. Furthermore, due to the arrangement of the brightness adjusting module, when the display screen needs brightness adjustment, the brightness adjusting module outputs related signals to the display screen. The display screen automatically adjusts the brightness.

Description

technical field [0001] The invention relates to the technical field of drive circuits, in particular to a TCON drive circuit applied to notebooks. Background technique [0002] At present, a notebook computer, also known as a notebook, portable or laptop, is a small, portable personal computer. Laptops usually weigh 1-3 kg. Its development trend is that the volume is getting smaller and smaller, the weight is getting lighter and lighter, and the function is more and more powerful. Like a Netbook, which is commonly known as a netbook. The main difference between a laptop and a PC is its portability. Compared with desktop computers, notebook computers have similar structural components, but the advantages of notebook computers are still very obvious, and its main advantages are small size, light weight, and easy to carry. Generally speaking, portability is the biggest advantage of notebooks over desktop computers. The weight of a general notebook computer is only about 2 k...

Problems solved by technology

First, the existing TCON drive circuit generally has three output modules, which leads to insufficient LVDS signals input to the display screen, which in turn leads to low resolution of the display screen and cannot meet the high-definition requirements; second, the current Some TCON drive circuits do not have related modules inside to absorb the surge current. As a result, the existing TCON drive circuit may not work properly due to excessive surge current, and thus cannot output the processed LVDS stably. The signal is sent to the display screen to make the display screen image stable; thirdly, the existing TCON drive circuit, when the display screen needs to be adjusted in brightness, the TCON drive circuit has no way to output the corresponding brightness adjustment signal to the display screen, so that the display The brightness of the screen is adjusted and changed, resulting in the poor functionality of the existing TCON drive circuit, which has certain limitations.
