systems like Raspbian, Ubuntu Mate and so on. Herein we take Raspbain as example.
Raspberry Pi cannot recognized and adapted to resolution of LCD plugged,
therefore, we need to set the resolution of Raspbian manually.
1. Download Raspbian image from Raspberry Pi website
2. Write the image to your TF card. (TF card need to be formatted)
3. Open config.txt file which located in root directory of SD card and add the
statements below to end of the file
max_framebuffer_height=1920
max_usb_current=1
config_hdmi_boost=10
hdmi_group=2
hdmi_force_hotplug=1
hdmi_mode=87
hdmi_timings=1080 1 26 4 50 1920 1 8 2 6 0 0 0 60 0 135580000 3
4. Save and eject the SD card. Plug the card to your Raspberry Pi

SCREEN SAVER
AMOLED screen has advantages of high contrast, wide color range, wide view angle
and so on. However, it is easy to face burn-in problem if displaying same content for
long time. As we test, the AMOLED cannot be restored if it display same static
image for 168 hours because of burn-in problem. In this case, we recommend you
to set screen saver and do not let the AMOLED display same static image for long time
（cannot longer than 1h）.
You can install screen saver with command below:
sudo apt-get install xscreensaver
ORIENTATION SETTING
DISP L AY ROTATING
1. To rotating the display, you can append this statement to the config file
display_rotate=1 #1: 90; 2: 180; 3: 270
2. Reboot the Raspberry Pi
sudo reboot
TOUCH ROTATING
1. Install libinput
sudo apt-get install xserver-xorg-input-libinput

For Ubuntu-Mate OS, you need to install xserver-xorg-input-libinput-hwe-16.04
instead.
2. create an xorg.conf.d folder
sudo mkdir /etc/X11/xorg.conf.d
3. copy file 40-libinput-conf to the folder which we created
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
4. Append a statement to touchscreen part of the file as below:
