Program burning device for liquid crystal display screen T-CON logic board
Technical Field
The utility model relates to a liquid crystal display technical field, in particular to program burning device for liquid crystal display T-CON logical board.
Background
It is known that the lcd works in matrix display mode, and processes parallel signals, that is, if the tv signals decoded by the main board are directly sent to the lcd for display, the lcd cannot display. A device for converting serial signals into parallel signals is required, the liquid crystal display can display television signals, and therefore, a T-CON logic board is provided, and the T-CON logic board is a device for converting serial signals into parallel signals. The T-CON logic board has the same function as a video board in a CRT (cathode ray tube) in a liquid crystal television, but has the essential difference that the logic board is not a pure signal amplifier, and the input of the logic board is LVDS format signals instead of RGB. The logic board is used for processing LVDS or TTL image data signals sent by the digital board and clock signals by the shift register to store the image data signals, and the clock signals are converted into control signals capable of being recognized by the screen, namely row and column signals RSDS, so that MOSFET tubes in the screen are controlled to work to control the torsion degree of liquid crystal molecules.
