What does it mean on a TCON board CPV CKV CKVB STV STVP OE XAO RL UD VGH VGL

In this presentation several electronic concepts are developed in connection with the TCON board in a TFT LCD TV and the operation of the gate driver. The electronic content of this chip is detailed. Thus we find a bi-directional shift register, a level shifter, a voltage follower and logic gates including NAND. The operation of this assembly requires various voltages either in logic form such as the CPV, CKV, CKVB, STV, STVP, OE, XAO, R/L, U/D signal, or in analog voltage form such as VGH and VGL.
