Miniaturized T-CON board

Abstract

The invention discloses a miniaturized T-CON board which comprises a main chip, a chip module, a bus switching module, a storage module, a signal terminal and an output module. The signal terminal isrespectively and electrically connected with the bus switching module, the main chip and the chip module. The output end of the bus switching module is further respectively electrically connected to the output end of the storage module and the input end of the chip module, the main chip is also respectively connected to the output end of the storage module, the chip module and the output module electrically, and the chip module is further electrically connected to the output module. The board can avoid the occurrence of a large amount of address data resulting in address conflict situation, and can also simplify the connection relationship of electronic circuits, reduce the labor cost and improve the production efficiency. At the same time, the board can reduce the loss caused by the complex circuits, make products miniaturized and modularized and save the cost of PCB substrates.

Description

technical field [0001] The invention relates to the field of T-CON board structure, in particular to a miniaturized T-CON board. Background technique [0002] T-CON is also called logic board, screen driver board, and central control board. At present, the main general-purpose TCON board brand in China is Video Display Optoelectronics. The role of the TCON board is to convert the LVDS image data input signal sent by the digital board (the input signal includes RGB data signal, clock signal, and control signal) through the logic board, and convert it into an LVDS signal that can drive the LCD screen. Directly sent to the LVDS receiving chip of the LCD screen. By processing the shift register to store the image data signal, the clock signal is converted into a control signal that the screen can recognize, and the row and column signal RSDS controls the work of the MOSFET tube in the screen to control the twist of the liquid crystal molecules. Drive the LCD to display images...

Problems solved by technology

[0003] However, the existing T-CON board needs to connect multiple chips, so that the value of the register will be reset every time the power is turned on. Therefore, a large amount of address data will be stored on the bus, which may interfere with The addresses of other chips on the entire system conflict or have the risk of being incorrectly modified, resulting in abnormal screens or black screens on the TV; moreover, there are three main chips on the existing T-CON board, making these several The circuit connection of the main chip is relatively complicated, and each chip must be programmed during the production process, which increases labor costs and reduces production efficiency; at the same time, due to the complexity of electronic circuits, not only the degree of integration is low, but also increases A certain loss also makes the structure of the entire T-CON board larger, increasing the occupied space
