Lady... I don't know what you are smoking there but I definitely want some.
PS forget baidu or other chinese sites, use translate.google.com next time, at least is expected to give a decent translation.
With all due respect...would you be so kind not to mention again this "100 mm XY resolution" printer on this nanodlp forum? AFAIK SparkMaker uses a proprietary software...not nanodlp.
Wrong: nanodlp runs on rpi / non-rpi arm / windows / linux / macosx. and I think it's the only multiplatform free software of this kind. And it has distributed work *slicing on more powerful machines, printer control on rpi).
I don't have this screen (I use iPad screens, Full HD screens and 4K UHD screens) but I guess the following config.txt file will work:
hdmi_pixel_encoding=2
start_x=1
gpu_mem=128
disable_overscan= 1
#overscan_left=-16
#overscan_right=-16
#overscan_top=-16
#overscan_bottom=-16
framebuffer_width=2560
framebuffer_height=1440
max_framebuffer_width=2560
max_framebuffer_height=1440
hdmi_force_hotplug=1
hdmi_cvt= 2560 1440 30 1
hdmi_group=2
hdmi_mode=87
hdmi_drive=2
config_hdmi_boost=4
hdmi_ignore_edid=0xa5000080
Maybe you will need to tune it a little bit (invert the places for "2560" and "1440" stringsboth in framebuffer lines and in hdmi_cvt ...and maybe disable_overscan=0 and put some values in overscan.... for correction).
If you put this in config.txt and reboot the rpi3 you should see the boot screen (maybe the "rainbow" screen, then the 4 raspberries and some very small text...and after a while the clear screen).
Probably nothing wrong with the nanodlp software per se, you have a problem with the LCD configuration. You need to change the /boot/config.txt file. What kind of LCD screen and HDMI controller are you using?
Armbian 5.30/jessie. Three issues so far:
1. when I try do display a the calibration image there is an error / panic (exit to prompt):
2017/08/26 18:07:34.751888 {"Layer":"1","module":"Image","level":"Warning","msg":"Display layer public/plates/dynamic.png"}

Dynamic calibration, boundaries, full white, full HD ...the same result.

3. printing a plate - error but no panic (no exit to prompt):
2017/08/26 18:13:52.197417 {"Layer":"1","module":"Image","level":"Warning","msg":"Display layer public/plates/2/1.png"}

Framebuffer path is set to /dev/fb0.

/dev/fb0 seems to work : I can "fill" the screen with
cat /dev/urandom >/dev/fb0
and I can set a single pixel with
printf "\x00\xFF\xFF\x00" | dd bs=4 seek=$((100 * 1920 + 100)) >/dev/fb0
I've tried different distributions (raspbian from orangepi, armbiaan based ln ubuntu and jessie form armbian.com, both server and destop). I intend to use it with arduino mega/ramps/marlin or arduino uno/cncshield/grbl and I was not interested in pigpio (I commented it ). Tried the latest version (it was supposed to have framebuffer support). it still has an error about libbcm, I guess there is still some code specific to raspberry pi. It's no longer a priority to me (I've bought several Rpi2 second hand) but in case you want to give it another shot to make it non-rpi dependant I can test it (on the latrst armbian / desktop with libGLES2).
