The present invention teaches a signal processing method and a signal processing device for simplifying TCON. The method includes the steps of: receiving a low voltage differential signaling (LVDS) signal and decoding the LVDS signal to obtain TCON signal width, period, and look-up table. The LVDS signal includes a clock signal and five data signals. TCON parameters are encoded in the empty differential pairs in the first bits of the last two data signals within continuous cycles. The TCON parameters include TCON signal width, period, and look-up table. By the present invention, TCON obtains TCON parameters from LVDS in a same sequence as they are stored in prior art's EEPROM. TCON resource is as such saved, and an external EEPROM may be omitted for lower production cost, under identical operation condition.
