Embodiment Construction

[0050] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0051] The present invention is mainly aimed at 4K*2K ultra-high-definition LCD TVs that can realize the TCON main control function by using the main control SOC of the core, and proposes a new circuit system composed of a general core board and a TCON drive module, and adopts a new interface (U-P interface) to realize the connection between modules.

[0052] The specific embodiment of the present invention is:

[0053] as attached Image 6 As shown, the ultra-high-definition LCD TV circuit system includes a TCON drive module. This module integrates the TCON driver part, the upper screen interface and the U-P interface. The functional characteristics of the TCON driver module are matched with the specific TCONless screen, and through the U-P interface, it can be adapted to all general-purpose core boards.

[0054]The ultra-high-definition LCD...

Abstract

The invention discloses a circuit system of an ultra-high definition liquid crystal television. The circuit system comprises a TCON driving module and a universal core panel, wherein the TCON driving module integrates a TCON driving portion, an upper screen interface and a U-P interface; and the universal core panel comprises a master control SOC chip of the core, integrates the U-P interface and comprises a corresponding interface peripheral circuit. The U-P interface is used for connecting the universal core panel and the TCON driving module; and the quantity of PINs of the U-P interface is 60, and a PIN functional region comprises a VIN region, a GND region, an I2C signal region, a P2P region and a GPIO region. The invention also discloses the U-P interface. According to the circuit system disclosed by the invention, the state of the core panel in the liquid crystal television can be remarkably simplified, so that development, production and maintenance and management of an integral liquid crystal television product are simpler, and the operating efficiency of the product is increased.

Description

technical field [0001] The invention relates to a circuit system, in particular to an ultra-high-definition liquid crystal television circuit system and an interface, and belongs to the technical field of liquid crystal television control circuit systems. Background technique [0002] The TCON board is a necessary function module inside the LCD TV. Its function is to convert the data signal format (V-By-One, LVDS, EDP, etc.) sent by the movement board into a data signal format that can be recognized by the Source IC on the LCD screen. (MiniLVDS, USI-T, ISP, EPI and other formats), and provide the timing control signal on the screen to ensure that the image data sent by the core board can be displayed correctly by the LCD screen. The main functional area of ​​the TCON module includes the TCON main control part and the TCON driver part. Traditionally, the TCON main control part is realized by a dedicated TCON main control IC, as shown in the attached figure 1 As shown, the ma...
