Abstract
(EN)
A display panel (100) and a display apparatus (700), the display panel (100) comprising a first substrate (200), at least one reflective structure (400), a communication line (210), and a control circuit (500). The at least one reflective structure (100) is arranged on the first substrate (200). The at least one reflective structure (400) comprises a reflective layer (410) and an electrochromic layer (420) arranged on the reflective layer (410). The communication line (210) is arranged on the first substrate (200). The projection of the at least one reflective structure (400) on the first substrate (200) along the direction perpendicular to the first substrate (200) and the projection of the communication line (210) on the first substrate (200) along the direction perpendicular to the first substrate (200) at least partially overlap. The control circuit (500) is arranged on the first substrate (200). The control circuit (500) is connected to the electrochromic layer (420). The utilisation rate of the backlighting light source is increased and the display effects are improved.
