How to make Local Dimming mini LED TV Backlight

DIY Full array local dimming TV LED backlight
NOTE-1: It is OK to use hot glue, because melting point of hot glue is 100C, These LEDs got only 32C when i leaved them running for a while (not even close to 100C), For higher power LEDs different story !
NOTE-2: Cheapest OLED TV in my country when i shared this video was $443, I bought this TV for $66 only and modification is so cheap if you buy the components from Aliexpress.
NOTE-3: I didn't used multiplexing for LEDs because multiplexing needs Microcontroller, this is why i wired every single LED separately.
NOTE-4: I said in the video "They Invented", because this method already used in some luxury TVs but they are so expensive, so this is a cheap hack !
