only touch symbol scroll

What have you tried so far?

change the symbol style, but no useful.

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

split your screen into 2 parts by creating two base objects with width = H/2, height = V. these objects will be containers for left and right objects. and put all left objects into left container, right objects - into right container.

do you mean creating two screens and show them at sametime?

No. As I can see your UI can be devided into 2 equal parts. So I suggest

lv_obj_t * obj1 = lv_obj_create(NULL);
lv_obj_set_size(obj1, H/2, V);
lv_obj_align(obj1, LV_ALIGN_TOP_LEFT, 0, 0);

lv_obj_t * obj2 = lv_obj_create(NULL);
lv_obj_set_size(obj2, H/2, V);
lv_obj_align(obj2, LV_ALIGN_TOP_RIGHT, 0, 0);

set up transparent background for those objects, and border width = 0.
and use obj1 as parent when creating left side ui-elements, obj2 as parent when creating right side ui-elements
