The T-CON board receives raw pixel data from the main board and reformats it into specific control signals needed by the display panel’s column and row drivers. The T-CON is also responsible for generating critical analog reference voltages required by the Thin-Film Transistor (TFT) liquid crystal matrix. These voltages include: VGHcap V sub cap G cap H end-sub (Voltage Gate High): Typically , used to turn on the TFT switches for a specific row. VGLcap V sub cap G cap L end-sub (Voltage Gate Low): Typically
