Orange Pi One: why is the I2C device address not detected?

Question

linux

Background: there is an Opi One with Armbian on board, an lcd with an i2c adapter, and a python script that tries to display a single character on the display. I write the script using only
the well-known library https://github.com/duxingkei33/orangepi_PC_gpio_pyH3. The problem, as I think, is the ambiguous definition of the lcd address, because. when trying to determine it, we get the following picture:

and more SDA / SCK are pulled up after 5k, the i2c-dev / i2c-bcm2708 module is connected, smbus as well, the display initialization order according to the datasheet (tested on avr). As you can see, I'm at a dead end)
Perhaps someone has encountered such a problem, tell me a possible solution! Thanks in advance!
