Yep, your posted configuration is a sort of "AP/router" configuration, you want instead a station/router or station/bridge one
For the wireless settings, you need for the moment just (for a station/router):
/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa2-psk mode=dynamic-keys
supplicant-identity=MikroTik
/interface wireless
set [ find default-name=wlan1 ] country=<your_country> disabled=no mode=station ssid=<the_SSID_of_the_LCD> password=<the_password_of_the_LCD_if_any>
But the mAP right now has no ip addresses set, maybe you want to add a DHCP client to the wireless interface (presuming that the LCD screen is also running a DCHCP server:
/ip dhcp-client
add interface=wlan1
or set a suitable IP address in the LCD network:
/ip address
add address=w.x.y.z/24 interface=wlan1 network=w.x.y.0
and set an IP address to ether1 as well:
/ip address
add address=192.168.88.1/24 comment=defconf interface=bridge network=\
192.168.88.0
If you want instead a station/bridge, a bridge is needed, so you want a bridge (since you are running v7.20 in station-psudobridge mode you should have rstp disabled on the bridge):
/interface bridge
add name=bridge
/interface bridge set [find where name=bridge] protocol-mode=none
Later, if needed, we will talk about using a fixed, non-automatic MAC address on the bridge.
Assign (temporarily) an IP address to the bridge (otherwise you will only be able to connect to the device via MAC with Winbox):
/ip address
add address=192.168.88.1/24 comment=defconf interface=bridge network=\
192.168.88.0
(or whatever network the LCD screen is set to)
with both the wlan1 and ether1 interfaces added to it:
/interface bridge port
add bridge=bridge interface=wlan1
add bridge=bridge interface=ether1
Then you might also need a DHCP client on the bridge (that would get the IP address from the LCD screen if it actually runs a DHCP server):
/ip dhcp-client
add interface=bridge
(alternative to the fixed IP address seen before)
Then the wireless settings, you need for the moment just:
/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa2-psk mode=dynamic-keys
supplicant-identity=MikroTik
/interface wireless
set [ find default-name=wlan1 ] country=<your_country> disabled=no mode=station-pseudobridge ssid=<the_SSID_of_the_LCD> wpa2-pre-shared-key=<the_password_of_the_LCD_if_any>
