DISPLAY APPARATUS AND SEAM CORRECTION METHOD THEREOF

A display apparatus is provided. The display apparatus includes a display including a plurality of display modules, and a processor configured to measure a first voltage according to a current flowingthrough reference pixels operating in a light reception mode by a light emitted from first adjacent pixels, to measure a second voltage according to a current flowing through reference pixels operating in the light reception mode by a light emitted from second adjacent pixels, and in response to a difference between the measured voltages is larger than or equal to a predetermined threshold value,to adjust a gain with respect to the second adjacent pixels based on amplitudes of the first voltage and the second voltage, and the first adjacent pixels are included in a different display module from the second adjacent pixels. 提供一种显示装置。该显示装置包括：显示器，包括多个显示模块；以及处理器，被配置为根据流过借助从第一相邻像素发射的光而在光接收模式下操作的参考像素的电流来测量第一电压，根据流过借助从第二相邻像素发射的光而在光接收模式下操作的参考像素的电流来测量第二电压，以及响应于所测量的电压之间的差大于或等于预定阈值，基于第一电压和第二电压的幅度来调整关于第二相邻像素的增益，并且第一相邻像素包括在与第二
