Controlling LED intensity based on a detected photocurrent value

A method for controlling a plurality of light emitting diodes (LEDs), the method comprising:

• receiving, by processing circuitry from a set of sensing LEDs of the plurality of LEDs, a set of photocurrent value components indicative of a photocurrent value corresponding to an LED of the plurality of LEDs wherein the plurality of LEDs form an LED matrix that includes a number of columns and a number of rows, wherein each sensing LED of the set of sensing LEDs is proximate to the LED in the LED matrix, wherein a switching device is electrically connected to the LED, and wherein the switching device is configured to control whether the LED receives an electrical signal from a power source;
• determining, by the processing circuitry, the photocurrent value based on the set of photocurrent value components;
• comparing, by the processing circuitry, the photocurrent value with a threshold photocurrent value;
• and
• controlling, by the processing circuitry based on the comparison of the photocurrent value with the threshold photocurrent value, an output current of the LED.
