Hello!
I have an 8-pin LCD jrm-6877
5V, GND, DATA, CLK, CS, LED, GND, PB
How to connect the LCD Display with Arduino UNO?
Can you make me a diagram?
There is a library to be installed?
I can't help you with the library. I think your out of luck on that one but it looks like your display uses SPI protocol.
This is my best guess on the wiring connection.
I think there is probably a better than 90% chance it is correct but I wouldn't use it until you get someone else to
confirm that.
LCD [Function Name] UNO
5V <= +Vcc => +5V
GND => GND => GND
DATA <= MOSI (UNO-PIN-11)
=> MISO (Not used)
CLK <= SCK (UNO-PIN-13)
CS <= SS (UNO-PIN-10)
LED (unknown) Could be backlight Anode (+3.3V to +5V)
GND => GND
PB (unknown, possibly a contrast adjust pin but that's just a wild guess)
SPI stands for Serial Peripheral Interface.
Knowing the wiring connection is not going to be much help without the datasheet for the display
that describes the data transfer format. If I were you I would NOT waste a whole lot of time trying to
get this to work. If you can find the information without too much trouble , great, but with display
prices dirt cheap from China you can get color TFT displays for $15 to $20 and ordinary two color
lcds for under $10. That's about all I can tell you .
It is manufactured by Freeborn Electronics Co, Ltd. Shenzhen http://detail.net114.com/chanpin/1003690432.html
I requested data sheet - I hope I was understandable 
The price of this LCD is 2.5 USD

Well, to me you are more so than that site you linked to.
Unfortunately I did not get any response on the LCD screen.
I do not know how to connect the LCD to the Arduino 
I think you are closer to knowing the connection to the arduino (from what I already gave you) than you are to knowing what code
to run or library to use.
