Screen to use for a children's alarm clock setup

[kenneho]

Hi.


we have a children's alarm clock similar to http://amzn.to/2aj137P, which is broken. I'm thinking about connecting my Raspberry Pi 3 model B to a screen, and set up my own similar type of alarm clock.
I basically only need to display a image during night time, and switch to another image during daytime, so the screen won't need to be touchscreen or anything. Only requirements is that it's fairly large (maybe 8 inches or thereabouts) and won't get ruined by having the same two images on hours at the time.

Any tips on specific screens that fit my needs would be greatly appreciated.

Best regards,
Kenneth

Well... I haven't set up the "video" version yet, but I've tested it. (I need to build a shelf for it.) I have a Pi2B attached to an RPF 7" touch screen. The key things I'm doing are:
Start "dclock" from the lxsession autostart to display the time.
Use crontab to to change the screen backlight from 225 for daytime to 15 for nighttime...just bright enough to see easily in a dark room.

We stream our local classical music station with mplayer for the alarm function, using crontab and manually kill the process, though a killall job would also work.

Excellent, thanks for the info on your hardware and software setup. I'll look into dclock and backlight. When it comes to the screen I'm hoping to find something cheaper that the RPF 7" screen.
