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.

Abstract: A display panel and a display device are provided. By means of a shielding structure with a floating potential provided over a projection of a sensing read line, when an electrical signal is transmitted on the sensing read line and a pixel data line, a shielding electric field will be formed between the shielding structure and the sensing read line. The presence of the shielding electric field can reduce capacitance between the sensing read line and adjacent pixel data line and effectively improve a signal-to-noise ratio during signal transmission.
