A wide variety of lcd screen arduino options are available to you, such as original manufacturer, odm.You can also choose from lcm, tft and standard lcd screen arduino,

What I understood was - ignoring the SD card module, they are using an LED driver IC to control the backlight, and a voltage regulator(with some auto reset IC) to feed the correct voltage to the LCD. Apart from that there"s some bypass caps on VCC and, some diodes on the LED driver IC.

I don"t know where the term "PLJ-6LED 2004A" came from since the first half (PLJ-6LED) seems to refer to a 6-digit, 7-segment display that does not show up on the Sainsmart website. The second half (2004A) comes up often since it refers to the 20x4 display size. It doesn"t much matter which one you are using since they are all more or less the same as long as the row of pins is at the upper left (and not the lower left) corner of the pc board.

I assume you mean the "New Liquidcrystal library" which is a replacement for, not an accessory to, the library that comes with the Arduino IDE. You must follow the installation instructions for this library which you can get here. I believe they also come packaged with the library. Basically you have to remove all traces of any other LiquidCrystal libraries for this one to compile.

I assume that you are referring to this ArduinoInfo page, and to the device he calls "I2C LCD DISPLAY VERSION 1:" That tutorial is actually the one I used when I was tinkering with my adapter which looks like that one and also came on a slow boat from the far east, Banggood in my case.

You also have to deal with the connections between the chip on the IC and the pins that go to the LCD module. These are specific to each pc board and the tutorial gives you the constructor that goes with each of the boards pictured. There is a "guesser" sketch available here if you want to go that route.

Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.

This is a powerful 3.5"" HMI, which is member of Nextion family. Features include: a 3.5" TFT 480 x320 resistive touch screen display, 4M Flash, 2KByte RAM, 65k colors.
