-## Thread-safe I2C with I2C Manager
-
-LVGL can use I2C to read from a touch sensor or write to a display, possibly
-many times a second. Meanwhile, other tasks may also want to read from i2c
-devices on the same bus. I2C using the ESP-IDF is not thread-safe.
-
-I2C Manager (`i2c_manager`) is a component that will let code in multiple threads
-talk to devices on the I2C ports without getting in each other's way. These drivers
-use a built-in copy of I2C Manager to talk to the I2C port, but you can also use 
-the I2C Manager component itself and have others play nice with LVGL and vice-versa.
-[Click here](i2c_manager/README.md) for details.
-
-
-## Backlight control
-
-Control of LCD's backlight is provided by separate module that is independent from the display driver.
-Configuration of the backlight controller can be found in menuconfig `LVGL ESP Drivers -> LVGL TFT Display controller`.
-
-There are three modes of operation:
-1. Off - No backlight control
-2. Switch - Allows ON/OFF control
-3. PWM - Allows brightness control (by Pulse-Width-Modulated signal)
