Help my viewpad screen display colour went weird

[ekou]

i had this viewpad for couple months now, it seems to be fine. sometime the playing some games and then went freeze. but thats not what the main problem is. today, again i use a viewpad playing with some apps, next thing i know, the display colour went weird. i tried to go to setting and change the display, but it doesn't have the option for me to do so. i try to uninstalled the app that cause the problem, but it doesn't change anything. restart and turn on again few times, and it still doesn't work. if anyone could help me. that will be great. thanks. i upload a few pics which hopefully give yous a rough idea of what the screen look like.
