Why only OLED use direct light emission, and on the other hand we only have LCD-based manipulation of backlight? Why can’t we have small LED blubs for each pixel of screen?

Answer 1

Per-pixel lighting behind an LCD panel is probably technically possible, but the cost and complexity are great enough that it makes more sense to move on to OLED, which uses multiple colored LED sub-pixels rather than light shining _through_ LCD sub-pixels.
