Abstract: The present application provides a display panel and a brightness compensation method thereof. Multiple sub-pixel units in each pixel unit share the same sensing unit, and the normal display process and optical inspection process of each pixel unit are carried out separately, so as to make each sub-pixel unit reach the target brightness. As a result, the number of sensing units in the optical compensation system could be reduced; the manufacturing process of the display panel could be simplified, and the manufacturing cost of the display panel could be reduced.
