  • Publication number: 20220130318
    Abstract: A display device includes a plurality of segmented display units arranged in a matrix, and a front display unit disposed on the plurality of segmented display units. The front display unit includes a plurality of transmission areas corresponding to main display areas of the plurality of segmented display units, and a supplementation display area corresponding to a separation area between the main display areas of adjacent segmented display units among the plurality of segmented display units. Due to the supplementation display area of the front display unit, the separation area between the main display areas of adjacent segmented display units may be prevented from being visible to a user. Therefore, the display device may realize both a large size screen and a high resolution.
