  • Publication number: 20210319746
    Abstract: The embodiments of the present disclosure disclose a display screen and a display device. A display screen (10) includes: a display panel (11), a compensation line assembly (12), a signal source circuit (13) and a compensation circuit (14). The display panel (11) includes a display area (111) and a non-display area (112). The compensation line assembly (12) is separately connected to each pixel unit. The signal source circuit (13) is configured to provide a preset driving voltage for each pixel unit. The compensation circuit (14) is configured to detect a real-time driving voltage of each pixel unit, determine a to-be-compensated pixel unit based on the preset driving voltage and the real-time driving voltage, and provide a compensation voltage for the to-be-compensated pixel unit. Therefore, brightness of the different display areas can be uniform, and brightness consistency of the display areas can be further improved.
