Welcome to electronicspoint.

What you experience is typical (alas) for cheap hardware from sources without a known reputation.

TX and RX are serial (UART) signal. Caution: these pins are 3.3V logic level only. Do not connect to a standard (PC) serial port. You connect the Rx pin with Tx of the arduino (observe the 3.3V logic level! Use a level shifter if necessary) and vice versa Tx of the LCD to Rx of the arduino.
Then you can control the module by sending commands and data via the serial port (UART).
The websites I found unfortunately do not offer a datasheet, Without such it will be hard to use the LCD. Was there any accompanying literature (datasheet) or software? Or at least a link where to find such?
