Description

Standard TCONless machine core board system of liquid crystal display television

Technical Field

The utility model relates to a LCD TV technical field, specific saying so, a LCD TV standard TCONless core board system.

Background

TCONless has become the basic technical cost-reducing means of the current lcd tv. The main chip SOC of the machine core integrates the TCON main control function, and integrates the TCON drive circuit and the interface on the core board, thus forming the TCONless core board. Through the FFC screen wire, the TCONless core board can directly send TCON related signals to a screen. Therefore, an independent TCON board is not needed in the liquid crystal television, and the cost of the whole television is reduced.

Different from standard interface protocols and interface definitions such as LVDS and V-By-One which are commonly adopted By a standard core board, the upper screen interface protocol and definition of the TCONless screen are different from screen manufacturers, even for the same screen manufacturer, the upper screen socket definitions adopted By TCONless screens with different sizes/models are different, so that the core board in the same functional state needs to derive different TCONless core boards when being matched with different TCONless screens. When the TCONless technology is applied to the entire lcd tv, the development efficiency of the lcd tv is seriously affected by more core board states, and the production management and the after-sales cost are significantly increased.

Although different TCONless core boards and screen lines are needed for matching different TCONless screens due to different screen interface definitions and signal requirements, the current TCONless technology application can generally share one set of core software by matching different TCONless screens in the aspect of core software. That is, the movement SOC may provide different power/control/data signals matched to a particular screen according to the difference in screen model. If the problem that the core board has a plurality of states and is complicated can be solved, the improvement of the standardized application of the TCONless technology can be facilitated.
